Qlikview Macro VBScript to print pdf and email will not run consistently - Fails in email
|
<p>I have been tearing my hair out over the last few days in trying to get this macro to work consistantly on the Windows scheduler.</p>
<p>Basically the workflow is as follows:</p>
<p>1) Windows Scheduler - Daily, uses Admin user credentials</p>
<p>2) Batch file - Reloads using /l</p>
<p>3) Reloads Qlikview application, which has triggers on post reload to save a pdf and email it using PDF Xchange and an html formatted e-mail to cover mobile.</p>
<p>I am getting such inconsistent behaviour that I cannot isolate the problem to any particular one thing. Sometimes it works, sometimes it doesn't. More often than not it fails on the Windows scheduler. There is no error since QV has just thrown up the VBScript window in the hidden process.</p>
<p>I've been changing permissions, which helped me reach a level of inconsistent performance as opposed to no performance.</p>
<p>In addition, it appears that you cannot pass variables to the PDF Xchange printer.</p>
<p>The code in the macro is as follows:</p>
<pre><code>sub ExportPDF
printReportPDF "\\SGH-SRV-FPS1\S-Drive\eCommerce\Data Analyst\Reporting\Daily E-Commerce Report\E-Commerce Daily Report.pdf"

ActiveDocument.GetApplication.Sleep 8000
end sub

Set WSHShell = CreateObject("WScript.Shell")
WSHShell.RegWrite "HKCU\Software\Tracker Software\PDF-XChange 3.0\OutputFile", pdfOutputFile, "REG_SZ"

<p>I've seen similar stuff in many other questions and usually there's some more or less clear message from which the problem cause can be deduced.</p>
<p>In my case there's just <code>Exception of type 'System.Web.HttpUnhandledException' was thrown.</code></p>
<p>How do I extract additional information from that <code>HttpUnhandledException</code> to try find why it was thrown?</p>

How to set plot size in ggplot or ggarrange?
|
<p>I work with Rmarkdown and I am creating many figures composed of different ggplot2 charts, using ggarrange. The problem is that I am not able to set different sizes for figures inside a single chunk. The only way I managed to set figure size is within chunk options, like:</p>
<p>{r Figure1, fig.height = 4, fig.width = 7}</p>
<p>Is there a way of setting the plot/grid size within each ggplot() or within ggarrange() function?</p>
<p><strong>Details, data & code:</strong></p>
<p>All my primary plots have the same size of the grid area, but the size of the final figures changes depending on the number of primary plots they contain. In addition, for annotation purposes (e.g. with annotation_figures() function), charts in the first row must have a larger top margin (for the title), while charts in the last row must have a larger bottom margin (for captions). The extra margins, to make room for title and captions (e.g. text grobs) should not alter the plot grid size, which I want to be the same for all plots inside a figure.</p>
<p>One example of a dataframe called "A1" that I have:</p>
<pre><code>library("pacman")
p_load(ggplot2, ggpubr, hrbrthemes, tidyverse)
year <- rep(seq(2010,2019, 1), each=3)
name <- rep(c("A", "B", "C"), times=10)
n1 <- c(0,0,1,0,2,1,1,1,1,2,0,2,0,2,1,3,2,0,1,4,2,2,9,4,8,11,8,7,9,8)
n2 <- c(7,3,1,14,1,1, 15,4,4,19,9,4,26,9,4,46,4,3,52,12,3,37,12,5,45,10,5,47,18,4)
name2 <- name
A1 <-data.frame(year,name,n1,n2,name2)
</code></pre>
<p>With this data frame, I build the first row of plots inside a chunk with specifications {fig.height = 4.3, fig.width = 7}. This plot row has three plots (made with facet_wrap) and a top margin of 0.3 inches to make room for title annotation in the final figure, and no bottom margin. This plot row also has its own title, which will function like a subtitle or a tag in the final figure.</p>
<pre><code>AA.1 <- A1 %>%
ggplot( aes(x=year, y=n1)) +
geom_line( data=A1 %>% dplyr::select(-name), aes(group=name2), color="grey", size=1.0, alpha=0.6) +
geom_line( aes(color=name), color="black", size=1.5 ) +
theme_ipsum() +
theme(
axis.text.x = element_text(size=12, angle=45),
axis.text.y = element_text(size=12),
legend.position="none",
plot.title = element_text(size=16),
panel.grid = element_blank(),
plot.margin = unit(c(0.3, 0.2, 0, 0.2), "in")) + #Top row charts have a 0.3 top margin
labs(title="A. TAK") +
scale_x_continuous(name ="",
limits=c(2010,2019),
breaks=c(seq(2010,2019,2)))+
scale_y_continuous(name ="",
limits=c(0,12),
breaks=c(seq(0,12,3)))+
facet_wrap(~name) +
theme(strip.text = element_text(size=13))
AA.1
</code></pre>
<p>Then I create the bottom row plots, inside another chunk, with a different figure height specification: {fig.height = 4.1, fig.width = 7}. This row is also made of three plots, which should be similar in all aesthetics aspects to the first row, although I am plotting a different variable, with different values (ref). This row has no top margins and a 0.1 inches bottom margin, to make room for captions.</p>
<pre><code>AA.2 <- A1 %>%
ggplot( aes(x=year, y=n2)) +
geom_line( data=A1 %>% dplyr::select(-name), aes(group=name2), color="grey", size=1.0, alpha=0.6) +
geom_line( aes(color=name), color="black", size=1.5 )+
theme_ipsum() +
theme(
axis.text.x = element_text(size=12, angle=45),
axis.text.y = element_text(size=12),
legend.position="none",
plot.title = element_text(size=16),
panel.grid = element_blank(),
plot.margin = unit(c(0, 0.2, 0.1, 0.2), "in")) + #Margins are different
ggtitle("B. REF") +
scale_x_continuous(name ="",
limits=c(2010,2019),
breaks=c(seq(2010,2019,2)))+
scale_y_continuous(name ="",
limits=c(0,60),
breaks=c(seq(0,60,10)))+
facet_wrap(~name) +
theme(strip.text = element_text(size=13))
AA.2
</code></pre>
<p>Finally, I arrange both sets of plots within a figure using ggarange(), and write the final title and captions with annotate_figure(). In this chunk, I set the total fig.height to 8.4 (the sum of two previous chunks).</p>
<pre><code>
figureA1 <- ggarrange(AA.1, AA.2,
ncol=1, nrow=2,
heights=c(1,1))
annotate_figure(
figureA1,
top = text_grob("Figura A.1 - TAK & REF",
color = "black", face = "bold", size = 18),
bottom = text_grob("Source: My.Data (2020)", face="italic", color = "black",
hjust = 1, x = 1, size = 12),)
</code></pre>
<p><strong>Possible solutions:</strong></p>
<ol>
<li><p>I would like that each plot had a total plot grid area of 4 inches. As the first plot has a top margin of 0.3 and a bottom margin of 0, I set fig.height to 4.3. As the second plot has a top margin of 0 and a bottom margin of 0.1, I set fig.height to 0.1. However, the plot grid area does not seem to be of the same size in both plots. Any ideas on how to fix this?</p>
</li>
<li><p>As the fig.height parameters are different for each plot, I need to split the code to build a figure into different chunks. I have many figures that are made in a similar fashion, and therefore, I would like to write a function to build and arrange plots within figures. However, I cannot write a function across different chunks.</p>
</li>
</ol>
<p>I think of two possible solutions for this second problem:</p>
<ol>
<li>Some way of setting the grid plot size within ggplot function (or the total plot area); or</li>
<li>Some way of setting each of the grid plots sizes within the ggarrange function;</li>
</ol>
<p>Anyone has an idea of how can I do that?</p>
<p>Perhaps the second would be even better. I tried to set the heights of the rows in ggarrange to be the same with the same, with heights argument ("heights=c(1,1)"). Also tried to make them proportional to each fig.height ("heights=c(5.3/5.1,1)"), but the second plot row grid still looks taller than the first one.</p>

Cant get value of hidden field after ajax Jquery
|
<p>I have a page that when a link is clicked it opens a pop up box to insert new charges. When this pop up box opens I use jquery load() function to insert a table with all the current charges (loaded from mysql) from a script on another page called load_charges.php. </p>
<p>The problem I am having is I can not access any of the hidden values from the content I just loaded I use: </p>
<pre><code>var charge_id = $(':hidden:first', $(this)).val();
</code></pre>
<p>this normally gets me the value of the first hidden element but it does not work if I am trying get the info from the page load from load_charges.php. I will list my code below:</p>

How to do instancing the right way in OpenGL.
|
<p>I am trying to use VBO and Instancing mechanism the most efficent way. I have a world based on voxels and I would like to draw them using least possible number of draw-calls. The code below prepares VBO with a quad: </p>
<pre><code>void VoxelView::initVBOs() {
/*--------------------- Main OpenGL Program ---------------------*/
/* Vertices of a triangle (counter-clockwise winding) */
float data[6][3] = {
// Left bottom triangle
{ -0.5f, 0.5f, 0.0f },
{ -0.5f, -0.5f, 0.0f },
{ 0.5f, -0.5f, 0.0f },
// Right top triangle
{ 0.5f, -0.5f, 0.0f },
{ 0.5f, 0.5f, 0.0f },
{ -0.5f, 0.5f, 0.0f }
};
/*---------------------- Initialise VBO - (Note: do only once, at start of program) ---------------------*/
/* Create a new VBO and use the variable "triangleVBO" to store the VBO id */
glGenBuffers(1, &triangleVBO);
/* Make the new VBO active */
glBindBuffer(GL_ARRAY_BUFFER, triangleVBO);
/* Upload vertex data to the video device */
glBufferData(GL_ARRAY_BUFFER, 6 * 3 * sizeof(float), data, GL_STATIC_DRAW);
/* Specify that our coordinate data is going into attribute index 0(shaderAttribute), and contains three floats per vertex */
glVertexAttribPointer(shaderAttribute, 3, GL_FLOAT, GL_FALSE, 0, 0);
/* Enable attribute index 0(shaderAttribute) as being used */
glEnableVertexAttribArray(shaderAttribute);
/* Make the new VBO active. */
glBindBuffer(GL_ARRAY_BUFFER, triangleVBO);
/*-------------------------------------------------------------------------------------------------------*/
/*--------------------- Load Vertex and Fragment shaders from files and compile them --------------------*/
/* Read our shaders into the appropriate buffers */
vertexSource = filetobuf("Shaders/exampleVertexShader1.vert");
fragmentSource = filetobuf("Shaders/exampleFragmentShader1.frag");
/* Assign our handles a "name" to new shader objects */
vertexShader = glCreateShader(GL_VERTEX_SHADER);
fragmentShader = glCreateShader(GL_FRAGMENT_SHADER);
/* Associate the source code buffers with each handle */
glShaderSource(vertexShader, 1, (const GLchar**)&vertexSource, 0);
glShaderSource(fragmentShader, 1, (const GLchar**)&fragmentSource, 0);
/* Free the temporary allocated memory */
free(vertexSource);
free(fragmentSource);
/* Compile our shader objects */
glCompileShader(vertexShader);
glCompileShader(fragmentShader);
/*-------------------------------------------------------------------------------------------------------*/
/*-------------------- Create shader program, attach shaders to it and then link it ---------------------*/
/* Assign our program handle a "name" */
shaderProgram = glCreateProgram();
/* Attach our shaders to our program */
glAttachShader(shaderProgram, vertexShader);
glAttachShader(shaderProgram, fragmentShader);
/* Bind attribute index 0 (shaderAttribute) to in_Position*/
/* "in_Position" will represent "data" array's contents in the vertex shader */
glBindAttribLocation(shaderProgram, shaderAttribute, "in_Position");
/* Link shader program*/
glLinkProgram(shaderProgram);
</code></pre>
<p>I am rendering the quad the following way: </p>
<pre><code>void VoxelView::renderVBO()
{
/* Set shader program as being actively used */
glUseProgram(shaderProgram);
/* Set background colour to BLACK */
glClearColor(0.0, 0.0, 0.0, 1.0);
/* Clear background with BLACK colour */
glClear(GL_COLOR_BUFFER_BIT);
/* Actually draw the triangle, giving the number of vertices provided by invoke glDrawArrays
while telling that our data is a triangle and we want to draw 0-3 vertexes
*/
glDrawArrays(GL_TRIANGLES, 0, 6);
}
</code></pre>
<p>I would like to draw this quad (which uses VBO) multiple times using the instancing mechanizm. I would like it to fe fairly simple as I want to implement it for more sophisticated code. I know that I should use <strong>glDrawElementsInstanced</strong> method to use instancing but I don't know how to do it. Does anybody know how to do it?</p>

Is it intended by the C++ standards committee that in C++11 unordered_map destroys what it inserts?
|
<p>I've just lost three days of my life tracking down a very strange bug where unordered_map::insert() destroys the variable you insert. This highly non-obvious behaviour occurs in very recent compilers only: I found that clang 3.2-3.4 and GCC 4.8 are the <strong>only</strong> compilers to demonstrate this "feature".</p>
<p>Here's some reduced code from my main code base which demonstrates the issue:</p>
<pre class="lang-cpp prettyprint-override"><code>#include <memory>
#include <unordered_map>
#include <iostream>
int main(void)
{
std::unordered_map<int, std::shared_ptr<int>> map;
auto a(std::make_pair(5, std::make_shared<int>(5)));
std::cout << "a.second is " << a.second.get() << std::endl;
map.insert(a); // Note we are NOT doing insert(std::move(a))
std::cout << "a.second is now " << a.second.get() << std::endl;
return 0;
}
</code></pre>
<p>I, like probably most C++ programmers, would expect output to look something like this:</p>
<pre><code>a.second is 0x8c14048
a.second is now 0x8c14048
</code></pre>
<p>But with clang 3.2-3.4 and GCC 4.8 I get this instead:</p>
<pre><code>a.second is 0xe03088
a.second is now 0
</code></pre>
<p>Which might make no sense, until you examine closely the docs for unordered_map::insert() at <a href="http://www.cplusplus.com/reference/unordered_map/unordered_map/insert/" rel="noreferrer">http://www.cplusplus.com/reference/unordered_map/unordered_map/insert/</a> where overload no 2 is:</p>
<pre class="lang-cpp prettyprint-override"><code>template <class P> pair<iterator,bool> insert ( P&& val );
</code></pre>
<p>Which is a greedy universal reference move overload, consuming anything not matching any of the other overloads, and <em>move constructing</em> it into a value_type. So why did our code above choose this overload, and not the unordered_map::value_type overload as probably most would expect?</p>
<p>The answer stares you in the face: unordered_map::value_type is a pair<<em>const</em> int, std::shared_ptr> and the compiler would correctly think that a pair<<em>int</em>, std::shared_ptr> isn't convertible. Therefore the compiler chooses the move universal reference overload, and that destroys the original, <strong>despite</strong> the programmer not using std::move() which is the typical convention for indicating you are okay with a variable getting destroyed. Therefore the insert destroying behaviour is in fact <em>correct</em> as per the C++11 standard, and older compilers were <em>incorrect</em>.</p>
<p>You can probably see now why I took three days to diagnose this bug. It was not at all obvious in a large code base where the type being inserted into unordered_map was a typedef defined far away in source code terms, and it never occurred to anyone to check if the typedef was identical to value_type.</p>
<p>So my questions to Stack Overflow:</p>
<ol>
<li><p>Why do older compilers not destroy variables inserted like newer compilers? I mean, even GCC 4.7 doesn't do this, and it's pretty standards conforming.</p></li>
<li><p>Is this problem widely known, because surely upgrading compilers will cause code which used to work to suddenly stop working?</p></li>
<li><p>Did the C++ standards committee intend this behaviour?</p></li>
<li><p>How would you suggest that unordered_map::insert() be modified to give better behaviour? I ask this because if there is support here, I intend to submit this behaviour as a N note to WG21 and ask them to implement a better behaviour.</p></li>
</ol>

How To Use List Adapter
|
<p>My app displays information from a database in a ListView. </p>
<p>In the ListView, there is also a VideoView which is supposed to load and play a video from my website.</p>
<p>In a separate app with only this function, I got it to work. The difference is that in the working app the videoview is located IN the <em>activity_main.xml</em> file, whereas in my new app, the videoview is located in a separate list_item.xml file which is loaded into activity_main.xml as a ListView.</p>
<p>I was told by another stack overflow user that because the VideoView is not in activity_main.xml, I'd have to create a ListAdapter and have the getView() method of the list adapter reference my list_item.xml layout file.</p>
<p>I found a tutorial on ListAdapters but it seemed that the context was too different from what I'm trying to achieve for me to be able to adapt it to my use.</p>
<p>Can someone help me understand how I might go about implementing a ListAdapter that would work with my current code?</p>
<p>Thanks in advance, I really appreciate the help.</p>

Trying to return the value from std::variant using std::visit and a lambda expression
|
<p>Suppose there exists a variant v defined as follows:</p>
<pre><code>std::variant<int,char,double,bool,std::string> v;
</code></pre>
<p>I am trying to get the underlying value from a std::variant using std::visit or std::get.</p>
<p>I tried doing this naively:</p>
<pre><code>constexpr size_t idx = v.index();
auto k = std::get<idx>(v);
</code></pre>
<p>But then learned that this will fail if the variant v is not a constexpr itself. And even then there may be problems with using std::string (due to the definition of the destructor for std::string).</p>
<p>My 2nd attempt was to try and do the following:</p>
<pre><code>auto k = std::visit([](auto arg){return arg;}, v);
</code></pre>
<p>But received this:</p>

<p>I'm stuck as to why the std::visit call does not work. I thought I supplied a trivial lambda expression which takes all possible types for the variant and returns the underlying value but it appears I am misunderstanding something.</p>
<p>I want to use std::variant now (after initially considering std::any (see <a href="https://stackoverflow.com/questions/52085547/avoid-writing-the-same-repetitive-type-checking-code-with-stdany">avoid writing the same repetitive type-checking code with std::any</a>) but I need a way to return the contained value. Any help would be greatly appreciated. Thank you very much.</p>

recording and saving audio on Android

<p>I'm developing an android (2.2) app to record audio. The code seems to run fine and even saves the files on the SD Card, but when I try and play the audio files on my Mac nothing happens. Almost like the files are empty. I've tried saving them as .mp3 and .wav but no luck. My code is below:</p>
<pre><code>import java.io.File;

private File outfile = null;
public AudioRecorder(){}
public void startRecording(String audioFile) throws IOException {
String state = android.os.Environment.getExternalStorageState();
if(!state.equals(android.os.Environment.MEDIA_MOUNTED)) {
throw new IOException("SD Card is not mounted. It is " + state + ".");
}
// make sure the directory we plan to store the recording in exists
File directory = new File(path).getParentFile();
if (!directory.exists() && !directory.mkdirs()) {
throw new IOException("Path to file could not be created.");
}
try{
File storageDir = new File(Environment
.getExternalStorageDirectory(), "/audio/");
storageDir.mkdir();
outfile=File.createTempFile(audioFile, ".wav",storageDir);
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(outfile.getAbsolutePath());
}catch(IOException e){
e.printStackTrace();

how to use enum with DescriptionAttribute in asp.net mvc
|
<p>I am new to asp.net MVC. I am trying to use dropdown control on my view page, which populates from enum. I also want to add custom descriptions to dropdown values. I searched so many examples, but no one posted how to populated description on view page. Here is my code:</p>
<p>ViewModel:</p>
<pre><code>public enum SearchBy
{
[Description("SID/PID")]
SID = 1,
[Description("Name")]
Name,
[Description("Birth Date")]
DOB,
[Description("Cause#")]
Cause
}

Please help me, where I am making mistake. Thank you</p>
<p><strong>UPDATE:</strong>
I got solution for this from Nico. And I researched little bit on this. I am updating this post with solution because it may useful to others, who are new to MVC

Stacking multiple plots, vertically with the same x axis but different Y axes in R

<p>I have a data.frame with multiple time series vectors against a date:time vector. I would like to plot all of the relevant vectors, vertically stacked on separate graphs with the same X axis but unique Y axes.

BroadcastReceiver for ACTION_MEDIA_BUTTON not working
|
<p>I am writing an Android application for version 4.0.3 (ICS) of the Android OS. The issue is that I am not getting the output from my Log.d() in the onReceive() method of the BroadcastReceiver which means my application is not properly handling the broadcast.</p>
<p>I have read countless questions about how to run code upon a ACTION_MEDIA_BUTTON being clicked. I have even copy + pasted code when mine did not work, just to see if it would work.</p>
<p>The ACTION_MEDIA_BUTTON I want to handle is the <strong>single</strong> button on earphones that allow a user to pickup / end calls, play / pause music. <strong>Instead of my application handling this button, when I click it, the stock music player on my Nexus S Android starts playing a song</strong>.</p>
<p>I have not placed my code in another class, maybe this is why it's not working?</p>
<p>Here's the code found on the onCreate() method (this specific code I copied off a website after the code I wrote didn't work):</p>
<pre><code>IntentFilter mediaButtonFilter = new IntentFilter(
Intent.ACTION_MEDIA_BUTTON);
mediaButtonFilter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
BroadcastReceiver brMediaButton = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
Log.d("Event", "Media button!");
this.abortBroadcast();
KeyEvent key = (KeyEvent) intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
if(key.getAction() == KeyEvent.ACTION_UP) {
int keycode = key.getKeyCode();
if(keycode == KeyEvent.KEYCODE_MEDIA_NEXT) {
Log.d("TestApp", "Next Pressed");
} else if(keycode == KeyEvent.KEYCODE_MEDIA_PREVIOUS) {
Log.d("TestApp", "Previous pressed");
} else if(keycode == KeyEvent.KEYCODE_HEADSETHOOK) {
Log.d("TestApp", "Head Set Hook pressed");
}
}
}
};
registerReceiver(brMediaButton, mediaButtonFilter);
</code></pre>
<p>All I really need to test for is the KEYCODE_HEADSETHOOK but it doesn't hurt to have the other code there for testing, I'll fix it up once I can get everything working correctly.</p>
<p>In my manifest:</p>
<pre><code><intent-filter android:priority="2147483647" >
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</code></pre>
<p>I originally thought this may be a permissions issue since I didn't specify any permissions for this however I didn't receive any error message.</p>
<p>Like I said earlier, I have tried many variations of this. One example was the use of the code at this link <a href="https://stackoverflow.com/questions/6603170/broadcastreceiver-onreceive-problem-action-media-button-android">broadcastreceiver onReceive problem ACTION_MEDIA_BUTTON Android</a> with CommonsWare's corrections. Again, however, I modified it so it wasn't in a seperate class.</p>
<p>Thank you in advance for your help.</p>

Can someone explain the Spring web.xml file?
|
<p>I'm new to Java Enterprise and to Spring but I have a strong grasp of standard Java. I am looking through an existing web application project. The project uses Tomcat/Spring/Hibernate which I understand is fairly common. It also uses DWR for remote method invocations. I'm finding it somewhat difficult to separate responsibilities: what Tomcat is responsible for, what Spring is responsible for, how a request gets from one to the other, and how the major pieces of Spring fit together. I've read a great deal of documentation on Spring, particularly about beans and bean factory and am still in process of reading more. Any advice you guys have would be welcome, but I'll provide some specific questions.</p>
<p>Question 1: Where does the web.xml fit into things (when is it used/called, and where is it called from)? </p>
<p>Code sample 1:</p>
<pre><code> <servlet>
<servlet-name>qrst</servlet-name>
<display-name>qrst Servlet</display-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
</code></pre>
<p>What does the above snippet do (or, what does it cause to happen)? At some point in my web app qrst.jsp gets used; is it the DispatcherServlet that calls qrst.jsp using the servlet name? Else what is the significance of the servlet name? What is load on startup?</p>
<p>Code sample 2:</p>
<pre><code><context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/someLocation/some-servlet.xml
</param-value>
</context-param>
</code></pre>
<p>Links or explanation of what the above does? I can see from looking at the XML file that it contains bean definitions and I do understand what beans are and how they are used, but I don't know any other details about this and would like to.</p>
<p>Code sample 3:</p>
<pre><code><servlet>
<servlet-name>dwr-invoker</servlet-name>
<display-name>DWR</display-name>
<servlet-class>
org.directwebremoting.servlet.DwrServlet
</servlet-class>
<init-param>
<param-name>classes</param-name>
<param-value>
somepackage.someclass
</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
</code></pre>
<p>From what I read about beans, I believe those init-param elements are just parameters that get set in the servlet's java class. What's the significance of the servlet name, and what about the load on startup? The web app somehow "knows" when an AJAX (dwr) call is happening versus when the web app is being loaded for the first time (when its loading for the first time it should use qrst.jsp). How does it know this? How does it decide to route the request to DWR instead of to qrst.jsp? Where does it do this?</p>
<p>Thanks. </p>

Cannot create PoolableConnectionFactory (Access denied for user ''@'localhost'
|
<p>I have been trying to set up a DatabaseConnectionPool for a web app for the last couple of days with no success. I have read the relevant sections of the Tomcat docs and a great deal around the subject and think I'm doing everything right, but obviously not because I keep on getting the following error:</p>
<pre><code>Cannot create PoolableConnectionFactory (Access denied for user ''@'localhost' (using password: YES))
</code></pre>
<p>I'm not getting the error when I start Tomcat running, but when I try to run the following servlet:</p>
<pre><code>package twittersearch.web;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import twittersearch.model.*;
public class ConPoolTest extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
Context ctx = null;
DataSource ds = null;
Connection conn = null;
try {
ctx = new InitialContext();
ds = (DataSource)ctx.lookup("java:comp/env/jdbc/twittersearchdb");
conn = ds.getConnection();
if(conn != null) {
System.out.println("have a connection from the pool");
}
} catch(SQLException e) {
e.printStackTrace();
} catch(NamingException e) {
e.printStackTrace();
} finally {
try {
if(conn!=null) {
conn.close();
}
} catch(SQLException e) {
e.printStackTrace();
}
}
}
}
</code></pre>
<p>The context for the webapp is:</p>
<pre><code><?xml version='1.0' encoding='utf-8'?>
<Context>
<!-- Configure a JDBC DataSource for the user database -->
<Resource name="jdbc/twittersearchdb"
type="javax.sql.DataSource"
auth="Container"
user="root"
password="mypwd"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/twitter"
maxActive="8"
maxIdle="4"/>
</Context>
</code></pre>
<p>What I really don't understand is why the error isn't saying that the access is denied to 'root'@'localhost' when I've specified that that's the user.</p>
<p>What I've tried:</p>
<p>Do I have a duplicate context.xml? No. I deleted the default on in Tomcat 6.0/conf. I tried putting a context.xml in [mywebappname]/META-INF/context.xml but not only did this not work, but resulted in the creation of a file named TwitterSearch.xml which was autogenerated and put in the Tomcat 6.0/conf/Catalina/localhost directory. So now I'm just editing that one and thats the only one I have.</p>
<p>Is it the version of Tomcat? Well, I completely reinstalled the latest version of Tomcat 6.0 so I don't think it's that.</p>
<p>Are we missing some jars? I have the tomcat-dbcp.jar, jconnector.jar and all the other ones that I think I'm meant to have in the Tomcat 6.0/lib directory.</p>
<p>When I look at the passwords in the MySQL database they seem to have been coded for security purposes into a long alpha-numeric string. Is this normal? Should I have this in my context.xml or just the normal password?</p>
<p>I really don't know how I can sort this out and would really appreciate some expert advice.</p>
<p>Many thanks in advance.</p>

No service for type 'Microsoft.AspNetCore.Identity.RoleManager error

<p>I'm setting up user roles on a ASP.NET CORE 2.1 application. But when I try to use the RoleManager it shoots into error. The error I get is: </p>
<pre><code>No service for type 'Microsoft.AspNetCore.Identity.RoleManager`1[Microsoft.AspNetCore.Identity.IdentityRole]' has been registered.)'

<p>I've looked through the whole application to see if <code>IdentityUser</code> is still anywhere, since I've created a class that inherits from it ( ApplicationUser ), but everything else seems correct. Adding <code>services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();</code>
gives a runtime error stating: <code>NotSupportedException: Store does not implement IUserRoleStore<TUser>.</code> Adding <code>Service.AddDefaultIdentity()</code>instead of <code>AddIdentity()</code>doesn't work either.</p>

Running powershell script within python script, how to make python print the powershell output while it is running
|
<p>I am writing a python script which checks various conditions and runs a powershell script accordingly to help me automate migration from windows XP to windows 7. The powershell script gives its own output giving the user updates as to what is happening. I would like to take the output of the powershell script and print it as output of the python script. I have looked around at some questions which seem to want to do the same thing but they don't seem to be working for me. Initially I tried using</p>
<pre><code>import subprocess
subprocess.call(["C:\Users\gu2124\Desktop\helloworld.ps1"])
</code></pre>
<p>As was suggested here <a href="https://stackoverflow.com/questions/14508809/run-powershell-function-from-python-script">Run PowerShell function from Python script</a> but I found out that this waits for the program to execute first and does not give output so I found out I need to use <code>subprocess.Popen()</code> as was suggusted here <a href="https://stackoverflow.com/questions/4668610/use-popen-to-execute-a-powershell-script-in-python-how-can-i-get-the-powershell">Use Popen to execute a Powershell script in Python, how can I get the Powershell script's output and update it to web page?</a> so I tried this</p>

AttributeError: DebugOutput instance has no attribute 'fileno'
</code></pre>
<p>I'm not completely sure what this means but from what I think I understand after reading this <a href="https://stackoverflow.com/questions/5903501/attributeerror-stringio-instance-has-no-attribute-fileno">AttributeError: StringIO instance has no attribute 'fileno'</a> is that it is because I am messing with the stdout incorrectly. I looked a around more and I found this <a href="https://stackoverflow.com/questions/16544362/why-wont-my-python-subprocess-code-work">Why won't my python subprocess code work?</a> where the answers said to use <code>stdout=subprocess.PIPE</code> so I tried this </p>
<pre><code>import subprocess
subprocess.Popen(["C:\Users\gu2124\Desktop\helloworld.ps1"], stdout=subprocess.PIPE)
</code></pre>
<p>which also does not give me output
Finally I saw this <a href="http://www.pythonforbeginners.com/os/subprocess-for-system-administrators" rel="noreferrer">http://www.pythonforbeginners.com/os/subprocess-for-system-administrators</a> and changed my code to this </p>
<pre><code>import subprocess
p = subprocess.Popen(["powershell","C:\Users\gu2124\Desktop\helloworld.ps1"], stdout=subprocess.PIPE)
print p.communicate
</code></pre>
<p>I thought that it may because I am initially trying to run a powershell script from the command line so I have to open powershell first. When I type these commands directly into the command line it works the way it should but when I run it through the python script it gives this </p>
<pre><code><bound method Popen.communicate of <subprocess.Popen object at 0x00000000026E4A90>>
</code></pre>
<p>which is an improvement I guess but not the "Hello world" I was expecting.
I have no idea what I should try to do next to get this to work. Any help would be greatly appreciated</p>
<p>Also if the powershell script I am using is needed here it is </p>
<pre><code>$strString = "Hello World"
write-host $strString
function ftest{
$test = "Test"
write-host $test
}
</code></pre>
<p>EDIT: I tried upgrading to python 3.3 like was suggested in the first answer but I still can't get it to work. I used the command <code>p = subprocess.Popen(['powershell.exe', "C:\\Users\\gu2124\\Desktop\\helloworld.ps1"], stdout=sys.stdout)</code> and am sure the file is there but am getting this error:</p>
<pre><code>Traceback (most recent call last):

JavaScript with Spring MVC doesn't work
|
<p>I downloaded login template which uses css and JavaScript. When I start it in default html format it displays ok, but when I put the same code to my Spring MVC 3 app and change format to jsp, javascript part is disabled. I can access external js files through my web browser, so I don't know where may be the problem.</p>
<p>This is the right look:
<img src="https://i.stack.imgur.com/l94Le.jpg" alt="right"></p>
<p>but this is what i get:

<pre><code><script language="javascript" type="text/javascript" src="js/niceforms.js"></script>
<link rel="stylesheet" type="text/css" media="all" href="css/niceforms-default.css" />
</code></pre>
<p>I only changed the location of external js and css resources but these files are accessable as I said.</p>
<p>This is my structure:</p>

<p>Thanks.</p>
<p>Edit:</p>
<p>I know where is the problem now, but still don't know how to solve it... Problem is in paths in external css files. I have something like this: <code>body {background-image:url('images/bg.jpg');}</code> but I get not found error in firebug because it tries to find the resource in <em>localhost:8080/sheedo/css/images/bg.jpg</em> and when I set absolute path of resource like <code>body {background-image:url('/images/bg.jpg');}</code> I get the same error too but it tries to find it in <em>localhost:8080/images/bg.jpg</em>. When I use <code>./images/bg.jpg</code> it's ok, but does exist any other solution instead of rewrite all paths in css files? I mean something like <code><mvc:resources ... ></code> is it possible ?</p>

"Dead letters encountered" as soon as actors are placed into router
|
<p>Here's what I'm finding, and for the life of me I can't navigate to the reason. I'm creating "printer" actors that basically either do nothing, or print a message based on the type of message they receive.</p>
<pre><code>class Printer extends Actor {
def receive = {
case m: SomeMessage => println( m.text )
case _ =>
}
}
</code></pre>
<p>I'm creating several of these actors:</p>
<pre><code>val actor4 = system.actorOf(Props[Printer], "t-4")
val actor5 = system.actorOf(Props[Printer], "t-5")
val actor6 = system.actorOf(Props[Printer], "t-6")
</code></pre>
<p>and throwing them into a vector:</p>
<pre><code>val routees2 = Vector[ActorRef](actor4, actor5, actor6)
</code></pre>
<p>I'm doing the above so that I can throw them into a router (and they will be under the router's control). When I run the spec up to this point I'm not having any issues. As soon as I place them in a router and run the spec I'm having problems. Here's the router:</p>
<pre><code>val router = system.actorOf(Props[Printer].withRouter(
BroadcastRouter(routees = routees2)), "router-to-transformers")
</code></pre>
<p>Now when I run the spec I have all sorts of dead letters...</p>
<pre><code>[INFO] [09/23/2013 17:10:21.468] [spider-akka.actor.default-dispatcher-6] [akka://spider/user/router-to-transformers] Message [akka.dispatch.sysmsg.DeathWatchNotification] from Actor[akka://spider/user/router-to-transformers#-1845250548] to Actor[akka://spider/user/rout

</code></pre>
<p>For the life of me I can't figure out what is going on here. I've added a link to a snippet of the test. The numbering, in the snippet, is weird because I've cut a bunch of different attempts that were commented out so as to not clutter the snippet. I'm focused on this dead-letters issue because I feel like when I added a more actors and actually started passing messages around, things weren't getting delivered...
<a href="http://snipt.org/AhVf0" rel="nofollow noreferrer">http://snipt.org/AhVf0</a></p>
<p>It's worth calling out that these actors are local. I've read something about actorFor being depreciated and I'm wondering if that is being used and is partly what is causing my issues? There are so many moving parts here though and not a lot of stable, COMPREHENSIVE, documentation. Any help would be greatly appreciated.</p>

Using a QThread in PyQT for serial communication (w. pyserial)
|
<p>I am pretty much a beginner when it comes to GUI programming.
I am using QT in combination with python bindings (PyQT4).</p>
<p><strong>What I am trying to do:</strong></p>
<ul>
<li>Setting up a <code>QThread</code> to read from & write to a Serial Port with
pyserial.</li>
<li>The main application should be able to emit new serial data via a
signal to the running <code>QThread</code>. and receive serial data from the
<code>QThread</code> with a signal.</li>
</ul>
<p>I started my own test implementation based on this code (<a href="https://stackoverflow.com/a/6789205/2706668" title="Link">Link</a>).
Prior to this I read the basics about <code>QThread</code>s and tried to understand how they are intended to be used.
The following test code is what I have come up with. I m sorry, I tried to keep it minmal,
but it is still 75 lines of code:</p>
<pre><code>from PyQt4 import QtCore, QtGui
import time
import sys
class SerialData(QtCore.QObject):
def __init__(self, message):
super(SerialData, self).__init__()
self.__m = message
def getMsg(self):
return self.__m
class SerialCon(QtCore.QObject):
finished = QtCore.pyqtSignal()
received = QtCore.pyqtSignal(SerialData)
def init(self):
super(SerialCon, self).__init__()
# TODO setup serial connection:
# setting up a timer to check periodically for new received serial data
self.timer = QtCore.QTimer()
self.timer.setInterval(400)
self.timer.timeout.connect(self.readData)
self.timer.start(200)
# self.finished.emit()
def readData(self):
self.received.emit(SerialData("New serial data!"))
print "-> serial.readLine() ..."
@QtCore.pyqtSlot(SerialData)
def writeData(self, data):
print "-> serial.write(), ", data.getMsg()
class MyGui(QtGui.QWidget):
serialWrite = QtCore.pyqtSignal(SerialData)
def __init__(self):
super(MyGui, self).__init__()
self.initUI()
def initUI(self):
bSend = QtGui.QPushButton("Send",self)
bSend.clicked.connect(self.sendData)
self.show()
@QtCore.pyqtSlot(SerialData)
def updateData(self, data):
print "Gui:", data.getMsg()
def sendData(self, pressed):
data = SerialData("Send me!")
self.serialWrite.emit(data)
def usingMoveToThread():
app = QtGui.QApplication(sys.argv)
guui = MyGui()
thread = QtCore.QThread()
serialc = SerialCon()
serialc.moveToThread(thread)
# connecting signals to slots
serialc.finished.connect(thread.quit)
guui.serialWrite.connect(serialc.writeData)
serialc.received.connect(guui.updateData)
thread.started.connect(serialc.init)
thread.finished.connect(app.exit)
thread.start()
sys.exit(app.exec_())
if __name__ == "__main__":
usingMoveToThread()
</code></pre>
<p><strong>My Problems:</strong></p>
<ul>
<li><p>In test code the signal emitted from the <code>SerialCon</code> object (which has
been moved to the <code>QThread</code>) seems to be not received by the
corresponding slot (in <code>MyGui</code>, <code>updateData</code>)</p></li>
<li><p>Sooner or later the running test code always causes a <code>Segmentation
fault (core dumped)</code>. Which makes me believe that I missed some
important bits.</p></li>
</ul>
<p>What could cause this?</p>
<p>Maybe I m taking a completely wrong approach? -
so if you have a better idea how to achieve this, I d be very grateful to hear about it!</p>
<p>Thanks a lot!</p>

Is still GWT pertinent for new projects?
|
<p>The question <a href="https://stackoverflow.com/questions/1205278">Why should I use jQuery instead of GWT?</a> may be outdated (as its answers). And <a href="https://stackoverflow.com/questions/812401">most</a> <a href="https://stackoverflow.com/questions/4673612">of</a> <a href="https://stackoverflow.com/questions/4886397">the</a> other SO related questions may also be outdated nowadays. So, let's update the <a href="http://en.wikipedia.org/wiki/State_of_the_art" rel="noreferrer">state of the art</a> about GWT relevance for new projects.</p>
<p><strong>GWT is more mature nowadays</strong></p>
<p>Since 2009 questions/answers, GWT has evolved and some JS frameworks are available in Java:</p>
<ul>
<li><a href="http://code.google.com/p/gwtquery/" rel="noreferrer">GwtQuery</a> for jQuery (gQuery)</li>
<li><a href="http://www.sencha.com/products/gxt/" rel="noreferrer">GXT</a> for ExtJS (former ExtGWT)</li>
<li><a href="http://code.google.com/p/smartgwt/" rel="noreferrer">Smart GWT</a> has superseded <a href="http://gwt-ext.com/" rel="noreferrer">GWT-ext</a></li>
<li>... and surely more ... (please feel free to append)</li>
</ul>
<p>And even more, Java code can be converted to standalone JS libraries: <a href="http://code.google.com/p/gwt-exporter/" rel="noreferrer">gwt-exporter</a></p>
<p><strong>But low-level JS frameworks may be enough</strong></p>
<p>But more I read, more I see web developers advising to turn his back on GWT and use directly JS frameworks (<a href="https://getfirebug.com/" rel="noreferrer">Firebug</a>, IDE plugins for JS frameworks...).</p>
<p><strong>Productivity</strong></p>
<p>However I like the idea of developing and debugging using the same IDE (Eclipse, Netbeans, IntelliJ IDEA...). I <em>think</em> I will be more productive... I should also think about Documentation and Community (forum reactivity as for this SO question)...</p>
<p><strong>Questions</strong></p>
<ol>
<li>For what kind of new 2014 project GWT should be (or not) considered?</li>
<li>Are there <em>pertinent</em> alternatives to GWT for easy AJAX web application development & deployment?</li>
<li>What are the current mode and trend?</li>
</ol>
<p><strong>My specific case</strong></p>
<p>I have just completed a POC (of an intranet web app) based on Python3 (<code>http.server.HTTPServer</code>) calling (POST) <code>bash</code> scripts (some processing in C++) and retrieving JSON data. Some JS (no framework) in the web page for rendering. So I am wondering the best option for next iteration.</p>
<p>But please answer this question about other cases too. I would prefer a general question/answer to be useful to many more people.</p>
<hr />
<p><strong>UPDATE October 2015</strong></p>
<p>GWT looks less active because no new release since 11 month. But in the past until <a href="https://en.wikipedia.org/wiki/Google_Web_Toolkit#History" rel="noreferrer">13 months between versions 2.4 and 2.5</a>. The <a href="https://github.com/gwtproject/gwt" rel="noreferrer">Git repo mirror</a> is still very active. Moreover GWT is extensible, and new features can come from GWT libraries without requiring new GWT framework release. See for example the <a href="https://en.wikipedia.org/wiki/Google_Web_Toolkit#Mobile" rel="noreferrer">most common mobile GWT libraries</a> and there corresponding release cycles. In the mean time the trend is to use Node.js everywhere! Adoption of GWT for new projects really depends on developers skills/motivation and project lifetime (turnover/training/maintenance). Some other criteria as reuse of available source code and time-to-market may also be taken into account... See excellent below answers.</p>

Spring annotation @Retryable - how to set an interceptor
|
<p>I am using a <code>@Retryable</code> annotation on a method in a <code>@Service</code>class</p>
<pre><code>@Service
@EnableRetry
public class PushService {
@Retryable(maxAttempts=5)
public Result pushIt(myMessage messageIn) {
...
}
}
</code></pre>
<p>and it works like a charme: I am getting a message directly from RabbitMQ, it is not acknowledged until either there is no error, or the number of attempts reach 5, and at that time the messages goes straight to the DLQ, right as I wanted.</p>
<p>My only problem is that I need to set the maxAttempts dynamically, from a property file. The solution should be setting an interceptor, but the only fact of having one causes an error, for example when I have :</p>
<pre><code>@Service
@EnableRetry
public class PushService {
@Retryable(interceptor="myInterceptor")
public Result pushIt(myMessage messageIn) {
...
}
}
</code></pre>
<p>where myInterceptor is defined as :</p>
<pre><code>@Bean
public StatefulRetryOperationsInterceptor myInterceptor() {
return RetryInterceptorBuilder.stateful().maxAttempts(5).build();
}
</code></pre>
<p>I get an infinite loop with the following exception:</p>

<li>Trac instance, accesible via <code>https://beta.mydomain.tld/trac</code></li>
<li>My own java web application, accessible via <code>http://beta.mydomain.tld/</code>, using a Proxy for the local Apache Tomcat on port 8080</li>
</ul>
<p>Please note that the first two are available via SSL, the third is not (yet). Now I need to make my web app available via https, but I want Trac and SVN Browser still to be accessible in their current location.</p>
<p>I.e. I am trying to configure apache2 to proxy all requests not starting with <code>svn</code> or <code>trac</code> to Tomcat.</p>
<p>For the existing SSL web apps, there's the following configuration</p>
<pre><code> <Location /svn/repos>
DAV svn
SVNParentPath /home/myuser/svn
SVNListParentPath on
AuthType Basic
AuthName "Subversion repository"
AuthUserFile /home/myuser/.htpasswd

<Location /trac>
SetHandler mod_python

PythonOption TracUriRoot /trac
AuthType Basic
AuthName "Trac"
AuthUserFile /home/myuser/.htpasswd

</Location>
</code></pre>
<p>I tried to add the following location, but it did not help anything...</p>
<pre><code> <Location />
ProxyPass http://localhost:8080
ProxyPassReverse http://localhost:8080/
</Location>
</code></pre>
<p>For further information, here is the complete apache2 configuration regarding the SSL part (without any of my failed trials in it - I think it is default trac configuration):</p>

throw exception without breaking loop in java
|
<p>I need to handle custom exception in java inside loop so i am throwing new custom exception but it breaks the loop. How we can manage to throw loop without breaking loop. Here is my code</p>
<pre><code> for (int i = 0; i < j; i++) {
File currFile = arrayOfFile1[i];
if (currFile.isFile()) {
if (currFile.exists()) {
try {
String fileName = currFile.getName();
if (fileName.startsWith("~$")) {
continue;
} else {
if ((fileName.endsWith(".xlsx")) || (fileName.endsWith(".xls"))) {
if (fileName.endsWith("_arch.xlsx") || fileName.endsWith("_arch.xls")) {
continue;
}
try {
IDSOutputGenerator.generateOutput(currFile.getAbsolutePath(), "", outputType,
false);
} catch (CheckErrorHandle e) {
throw new CheckErrorHandle();
}
}
else if (fileName.endsWith(".xml")) {
try {
IDSOutputGenerator.generateOutput(currFile.getAbsolutePath(), "", outputType,
false);
} catch (CheckErrorHandle e) {
throw new CheckErrorHandle();
}
} else {
throw new CheckErrorHandle(currFile.getAbsolutePath(), "File type not supported");
}
}

throw new CheckErrorHandle();

throw new CheckErrorHandle("", e.getMessage());

Ternary operator in LINQ where clause
|
<p>I am using linq for join multiple tables and write complex query. Here when i will have '0' as any parameter i.e. <code>CategoryId</code>, <code>GameId</code>, <code>LimitVariantId</code>, that means user has selected "All" from interface.</p>
<p>My Sql query, when I will pass parameter values greater than '0' is : </p>
<pre><code>select * from dbo.GameCombinations gc
inner join dbo.StakeBuyInByStakeCategories sbsc
on sbsc.StakeBuyInByStakeCategoryId = gc.StakeBuyInByStakeCategoryId
inner join dbo.GameTables gt
on gc.GameCombinationId = gt.GameCombinationId
where gc.CurrencyId=1 and gc.GameTypeId=2
and sbsc.StakeBuyInId=gt.BuyIn
and gc.CategoryId=4
and gc.GameId=7
and gc.LimitVariantId=23
and gc.StakeCategoryId in (3,5,6)
</code></pre>
<p>When I will pass CategoryId as <code>0</code> then My Sql query will be : </p>
<pre><code>select * from dbo.GameCombinations gc
inner join dbo.StakeBuyInByStakeCategories sbsc
on sbsc.StakeBuyInByStakeCategoryId = gc.StakeBuyInByStakeCategoryId
inner join dbo.GameTables gt
on gc.GameCombinationId = gt.GameCombinationId
where gc.CurrencyId=1 and gc.GameTypeId=2
and sbsc.StakeBuyInId=gt.BuyIn
--and gc.CategoryId=4
and gc.GameId=7
and gc.LimitVariantId=23
and gc.StakeCategoryId in (3,5,6)
</code></pre>
<p>So I don't need to include that fields in where clause. For that I had written the following LINQ:</p>
<pre><code>ProviderDB db = new ProviderDB();
try
{
IQueryable<dynamic> query;
if (StakeCategoryIdsByStakeBuyIn != null)
{
query = (from gc in db.GameCombinations.Where(x => x.CurrencyId == CurrencyId && x.GameTypeId == GameTypeId
&& CategoryId <= 0 ? true : x.CategoryId == CategoryId
&& GameId <= 0 ? true : x.GameId == GameId
&& LimitVariantId <= 0 ? true : x.LimitVariantId == LimitVariantId
&& StakeCategoryIdsByStakeBuyIn.Contains(x.StakeCategoryId)
)
join sbsc in db.StakeBuyInByStakeCategories
on gc.StakeBuyInByStakeCategoryId equals sbsc.StakeBuyInByStakeCategoryId
join gt in db.GameTables
on gc.GameCombinationId equals gt.GameCombinationId
join gx in db.Games
on gc.GameId equals gx.GameId into joined
from gx in joined.DefaultIfEmpty()
where gt.BuyIn == sbsc.StakeBuyInId
select new
{
GameTableId = gt.GameTableId,
Description = gt.Description,
BuyIn = gt.BuyIn,
Table = gx.GameName,
MaxAllowPlayer = gt.MaxAllowPlayer
}).Distinct();
}
else
{
query = (from gc in db.GameCombinations.Where(x => x.CurrencyId == CurrencyId && x.GameTypeId == GameTypeId
&& CategoryId == 0 ? true : x.CategoryId == CategoryId
&& GameId == 0 ? true : x.GameId == GameId
&& LimitVariantId == 0 ? true : x.LimitVariantId == LimitVariantId
&& StakeCategoryIdsByStakeBuyIn == null
)
join sbsc in db.StakeBuyInByStakeCategories
on gc.StakeBuyInByStakeCategoryId equals sbsc.StakeBuyInByStakeCategoryId
join gt in db.GameTables
on gc.GameCombinationId equals gt.GameCombinationId
join sb in db.StakeBuyIns
on gt.BuyIn equals sb.StakeBuyInId
join gx in db.Games
on gc.GameId equals gx.GameId into joined
from gx in joined.DefaultIfEmpty()
where gt.BuyIn == sbsc.StakeBuyInId
select new
{
GameTableId = gt.GameTableId,
Description = gt.Description,
BuyIn = sb.StakeBuyInValue,
Table = gx.GameName,
MaxAllowPlayer = gt.MaxAllowPlayer
}).Distinct();
}
</code></pre>
<p>But this will return all fields from my database. So Can any one help me to write these queries in LINQ with ternary condition that will return my filtered fields' records?</p>

Avoid using document.write() occurs when trying to load a dashboard page in Chrome
|
<p>So I have been stuck on this problem for longer than i'd care to admit but as a Angular newbie I am completely baffled.</p>
<p>So I am following some online tutorials in order to implement Gulp into an application I am working on and whenever I run the Gulp tasks I get an error in Chrome which states: </p>
<blockquote>
<p><strong>"[Violation] Avoid using document.write().(anonymous) @ (index):13"</strong></p>
</blockquote>
<p>and: </p>
<blockquote>
<p><strong>//\/script>".replace("HOST",
location.hostname)); //]]></strong></p>
</blockquote>
<p>I am even more confused as the index.html doesn't actually contain a document.write reference before execution. Also despite mostly following a tutorial when integrating Gulp I cannot seem to have the CSS background changes reflected on screen, could this be related to the previously mentioned error?</p>

Spring / Hibernate / JUnit - No Hibernate Session bound to Thread
|
<p>I'm trying to access the current hibernate session in a test case, and getting the following error:</p>
<blockquote>
<p>org.hibernate.HibernateException: No
Hibernate Session bound to thread, and

<p>I've clearly missed some sort of setup, but not sure what.</p>

How to execute a long dynamic query (greater than 4000) characters - again
|
<p>Note: I'm running under SQL Server 2008 R2...</p>
<p>I've taken the time to read dozens of posts on this site and other sites on how to execute dynamic SQL where the query is more than 4000 characters. I've tried more than a dozen solutions proposed. The consensus seems to be to split the query into 4000-character variables and then do:</p>
<pre><code>EXEC (@SQLQuery1 + @SQLQuery2)
</code></pre>
<p>This doesn't work for me - the query is truncated at the end of @SQLQuery1.</p>
<p>Now, I've seen samples how people "force" a long query by using REPLICATE a bunch of spaces, etc., but this is a real query - but it gets a little more sophisticated than that.</p>
<p>I have SQL View with a name of "Company_A_ItemView".</p>
<p>I have 10 companies that I want to create the same exact view, with different names, e.g.
"Company_B_ItemView"
"Company_C_ItemView"
..etc.</p>
<p>If you offer help, please don't ask why there are multiple views - just accept that I need to do it this way, OK?</p>
<p>Each company has its own set of tables, and the CREATE VIEW statement references several tables by name. Here's BRIEF sample, but remember, the total length of the query is around 6000 characters:</p>
<pre><code>CREATE view [dbo].[Company_A_ItemView] as
select
WE.[Item No_],
WE.[Location Code],
LOC.[Bin Number],
[..more fields, etc.]
from
[Company_A_Warehouse_Entry] WE
left join
[Company_A_Location] LOC
</code></pre>
<p>...you get the idea</p>
<p>So, what I am currently doing is:</p>
<p>a. Pulling the contents of the CREATE VIEW statement into 2 Declared Variables, e.g.</p>
<pre><code>Set @SQLQuery1 = (select text
from syscomments
where ID = 1382894081 and colid = 1)
Set @SQLQuery2 = (select
from syscomments
where ID = 1382894081 and colid = 2)
</code></pre>
<p>Note that this is how SQL stores long definitions - when you create the view, it stores the text into multiple syscomments records. In my case, the view is split into a text chunk of 3591 characters into the first syscomment record and the rest of the text is in the second record. I have no idea why SQL doesn't use all 4000 characters in the syscomment field. And the statement is broken in the middle of a word.</p>
<p>Please note in all my examples, all @SQLQueryxxx variables are declared as varchar(max). I've also tried declaring them as nvarchar(max) and varchar(8000) and nvarchar(8000) with the same results.</p>
<p>b. I then do a "Search and Replace" for "Company_A" and replace it with "Company_B". In the code below, the variable "@CompanyID" is first set to "Company_B":</p>
<pre><code>SET @SQLQueryNew1 = @SQLQuery1
SET @SQLQueryNew1 = REPLACE(@SQLQueryNew1, 'Company_A', @CompanyID)
SET @SQLQueryNew2 = @SQLQuery2
SET @SQLQueryNew2 = REPLACE(@SQLQueryNew2, 'Company_A',@CompanyID)
</code></pre>
<p>c. I then try:</p>
<pre><code>EXEC (@SQLQueryNew1 + @SQLQueryNew2)
</code></pre>
<p>The message returned indicates that it's trying to execute the statement truncated at the end of @SQLQueryNew1, e.g. 80% (approx) of the query's text.</p>
<p>I've tried CAST'ing the final result into a new varchar(max) and nvarchar(max) - no luck
I've tried CAST'ing the original query a new varchar(max) and nvarchar(max)- no luck</p>
<p>I've looked at the result of retrieving the original CREATE VIEW statement, and it's fine.</p>
<p>I've tried various other ways of retrieving the original CREATE VIEW statement, such as:</p>
<pre><code>Set @SQLQuery1 = (select VIEW_DEFINITION)
FROM [MY_DATABASE].[INFORMATION_SCHEMA].[VIEWS]
where TABLE_NAME = 'Company_A_ItemView')`
</code></pre>
<p>This one returns only the first 4000 characters of the CREATE VIEW </p>
<pre><code>Set @SQLQuery1 = (SELECT (OBJECT_DEFINITION(@ObjectID))
</code></pre>
<p>If I do a </p>
<pre><code>SELECT LEN(OBJECT_DEFINITION(@ObjectID))
</code></pre>
<p>it returns the correct length of the query (e.g. 5191), but if I look at @SQLQuery1, or try to </p>
<pre><code>EXEC(@SQLQuery1), the statement is still truncated.
</code></pre>
<p>c. There are some references that state that since I'm manipulating the text of the query after retrieving it, the resulting variables are then truncated to 4000 characters. I've tried CAST'ing the result as I do the REPLACE, e.g.</p>
<pre><code>SET @SQLQueryNew1 = SELECT (CAST(REPLACE(@SQLQueryNew1,
'Company_A',
@CompanyID) AS varchar(max))
</code></pre>
<p>Same result.</p>
<p>I know there are other methods, such as creating stored procedures for creating the views. But the views are being developed and are somewhat "in flux", so placing the text of the CREATE VIEW inside a stored proc is cumbersome. My goal is to be able to take Company_A's view and replicate it exactly - multiple times, except reference Company_B's view name and table names, Company_C's view name and table names, etc.</p>
<p>I'm wondering if there is anyone out there who has done this type of manipulation of a long SQL "CREATE VIEW" statement and try to execute it.</p>

How can I make viewpager loop?
|
<p>I want my ViewPager implementation to cycle between views instead of stopping at the last view. For example, if I have 3 views to display via a ViewPager, it should return back to the first View after the third View on fling instead of stopping at that third view. I want it to return to the first page/view when the user flings forward on the last page</p>

<p>I've read through multiple articles regarding this issue however they have all ended up with it not working, or are in vb.net. </p>
<p><strong>What I currently have:</strong></p>
<p>The reports are accessed via a URL which renders them as a PDF and saves them in the downloads folder when the user clicks on a button, these are given generic names such as OrderReport, OrderReport(1)... and so on.</p>

<ul>
<li>I would like to use C# to fetch this report if possible, and then specify a name for the PDF file and save it in the correct location. </li>
</ul>
<p>so for example I would like to save this report in a temporary folder for now "<strong>C:\temp</strong>" with the name <strong>OrderID-1</strong>. I am using C#</p>

How to add Custom Column in sales/order grid in Magento?
|
<p>I am trying to add custom columns to my sales/order grid. My columns will be the tracking number and the tile. The title is basically the courier code which shows you through which courier you have send you product.
So i have done some following things for this.</p>
<ol>
<li>I have copied the file from <code>magento/app/code/core/Mage/Adminhtml/Block/Sales/Order/Grid.php</code> to</li>
</ol>
<p>magento/app/code/local/Mage/Adminhtml/Block/Sales/Order/Grid.php</p>
<p>so that i can add columns and customize my sales/order grid.</p>
<ol start="2">
<li>In the file Grid.php, There is _prepareCollections() functions.</li>
</ol>
<p>Here the code goes into it. </p>
<pre><code>protected function _prepareCollection()
{
$collection = Mage::getResourceModel($this->_getCollectionClass());
$this->setCollection($collection);
$collection->getSelect();
$collection->getSelect()->join('sales_flat_shipment_track', 'main_table.entity_id =sales_flat_shipment_track.order_id',array('track_number'=> new Zend_Db_Expr('group_concat(sales_flat_shipment_track.track_number SEPARATOR ",")'),'title' => new Zend_Db_Expr('group_concat(sales_flat_shipment_track.title SEPARATOR ",")')));
return parent::_prepareCollection();
}
</code></pre>
<p>And Now i will add my columns here in my _prepareColumns() function. Code for that is</p>
<pre><code>protected function _prepareColumns()
{
$this->addColumn('track_number', array(
'header'=> Mage::helper('sales')->__(' Track Number'),
'width' => '80px',
'type' => 'text',
'index' => 'track_number',
));
$this->addColumn('title', array(
'header'=> Mage::helper('sales')->__('Title'),
'width' => '80px',
'index' => 'title',
));

<p>Now I am getting the columns Tracking Number and Title on my Grid. But in my tracking number ,its showing me the duplicate entries.
For example, If my tracking number is 12345678, It shows me two values which are same, Like this. 12345678,12345678. </p>
<p>Also in my title, It shows Federal Express,Federal express for two times. </p>
<p>What i want is two things, </p>
<p>a. First There can be 2 tracking nos, or more than that. But it should be shown like this. ex. 12345678,12345678900. It should be distinct. </p>
<p>For some of my order no it shows distinct. But most of them have duplicate entries.</p>
<p>b. Secondly if the courier is send by federal express and then if the product returns and we send by bluedart
then it should show federal express, bluedart .
But what i am getting is federal express,federal express, blue dart,blue dart. </p>
<p>It is showing me 4 times. </p>
<p>I don't know what exactly problem i am facing. Is der any database problem or the query i have written. </p>
<p>Please let me know whether </p>

}
</code></pre>
<p>This function is correct and also the query written in it. </p>
<p><strong>Edited PArt</strong></p>
<p>I also want to filter the track_number and title in my grid.php. I have tried some of the things. </p>
<p>This code goes in grid.php, </p>
<pre><code>protected function spaceSeparatedFilter($collection, $column)
{
$value = $column->getFilter()->getValue();
if (!$value) {
return $this;
}
//if there was a space input
else if(preg_match('/s+/', $value))
{
//explode by space, getting array of IDs
$val = explode(" ", $value);
//filter the collection, where collection index (order_id) is present in $val array
$this->getCollection()->addAttributeToFilter($column->getData('index'), array('in'=>$val));
}
else
{
//else use default grid filter functionality (like $value input)
$this->getCollection()->addAttributeToFilter($column->getData('index'), array('like' => '%'.$value.'%'));
}
return $this;
}
</code></pre>
<p>Now i have added filter condition to my addcolumn,</p>
<pre><code>$this->addColumn('track_number', array(
'header'=> Mage::helper('sales')->__(' Track Number'),
'width' => '80px',
'type' => 'text',
'index' => 'track_number',
'filter_condition_callback' => array($this, 'spaceSeparatedFilter'),
));
$this->addColumn('title', array(
'header'=> Mage::helper('sales')->__('Title'),
'width' => '80px',
'index' => 'title',
'filter_condition_callback' => array($this, 'spaceSeparatedFilter'),
));
</code></pre>
<p>But i am not able to filter in my sales/order grid. Please let me know the solution for this.</p>
<p>Thanks and Regards.</p>

<p>I have been beating my head against the wall and I cannot understand why this is happening. I am working with the new Architectural Components for Android and I am having problems updating a LiveData with a List of Objects.
I have two spinners. When i change the option in the first one, The second one must have its content changed. But this last part is not happening.
Can anyone help me?</p>

Calling a function without clicking anything
|
<p>I'm new in programming and I'm trying to call a function without any button or click event. I'm doing a table within a table using javascript function. Here's my code so far: <br><br></p>
<pre><code><html>
<head> <title> Hello </title> </head>
<body>
<table border=1>
<tr>
<td> Hello! <input type='hidden' value='0' id='theValue' /> <script> add(); </script> <div id='myDiv'> </div> </td>
</tr>
<script>
$ctra = 1;
$ctr1a = 1;
function add() {
var ni = document.getElementById('myDiv');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value -1)+ 2;
numi.value = num;
var newdiv = document.createElement('div');
var divIdName = 'my'+num+'Div';
newdiv.setAttribute('id',divIdName);
newdiv.innerHTML = "<table border=1>"+
"<tr>"+
"<td> Hello! <input type='hidden' value='0' id='theValue' /> <script> add(); </script> <div id=('" + divIdName + "')> </div> </td>"+
"</tr>"+
"</table>";
if($ctra<100){
ni.appendChild(newdiv);
$ctra++;
}
}
</script>
</table>
</body>
</html>
</code></pre>
<p><br>
When I run it, it displays<br></p>
<pre><code>"+ ""+ "
Hello!
"; if($ctra<100){ ni.appendChild(newdiv); $ctra++; } }
</code></pre>
<p><br>
in the browser. What could the problem be? Thank you in advance!<br><br>
<strong>EDIT</strong><br></p>
<pre><code>function add() {
var ni = document.getElementById('myDiv');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value -1)+ 2;
numi.value = num;
var newdiv = document.createElement('div');
var divIdName = 'my'+num+'Div';
newdiv.setAttribute('id',divIdName);

C++: get Boost working; questions on include path and linking library
|
<p>I was trying to use Boost.Tokenizer library. In my <code>PROG.cpp</code>, I have the following:</p>
<pre><code>#include <boost/tokenizer.hpp>
</code></pre>
<p>And my <code>Makefile</code> was initially something like</p>
<pre><code>CXX = g++-4.8
CXXFLAGS = ## some irrelevant flags
LDFLAGS = ## some irrelevant flags
SOURCES = PROG.cpp
OBJECTS = $(SOURCES:.cpp=.o)
TARGETS = PROG
$(TARGETS) : $(OBJECTS)
$(CXX) $(CXXFLAGS) -o $@ $^ $(LDFLAGS)
## other targets
</code></pre>
<p>It won't compile, since <code>boost/tokenizer.hpp</code> cannot be found:</p>
<pre><code>fatal error: boost/tokenizer.hpp: No such file or directory
</code></pre>
<p>Then I manually added the boost include path to <code>CXXFLAGS</code>:</p>
<pre><code>-I/opt/local/include/
</code></pre>
<p>(which is the path from MacPorts.)</p>
<p>Then I tried to include the Tokenizer library, but in <code>/opt/local/lib/</code> I have <code>libboost_atomic-mt.dylib</code>, <code>libboost_chrono-mt.dylib</code>, etc., but nothing like <code>tokenizer</code>. I was rather confused at the time. I supposed that still wouldn't work since the library was not linked against. Surprisingly, the program built, linked, and ran perfectly.</p>
<p>So I'm really confused now. Here are some questions:</p>
<p>(1) I did not link against boost explicitly, so boost is treated like standard library by the linker?</p>
<p>(2) If boost is treated like standard, why the headers are not standard?</p>
<p>(3) Why there are <code>libboost_atomic-mt.dylib</code>, <code>libboost_chrono-mt.dylib</code>, etc. but not <code>tokenizer</code>? Which dynamic library does <code>tokenizer</code> belong to?</p>
<p>I'm not very familiar with <code>g++</code> linking mechanism; speaking of boost, this is my very first program with boost. <strong>So I'd really appreciate detailed explanation.</strong> Thanks in advance!</p>
<p>For reference, this is what I extracted by <code>gcc -print-search-dirs</code>:</p>

How to clear v-model used with a select when options change
|
<p>I have a cascading select (two part select) where the options in the second dropdown are determined by the value of the first dropdown. I do this by having a computed property which is based off of the first select. This then feeds the options into the second select. This mostly works fine.</p>
<p>The problem I'm having is if I have selected an option in the second select (which through v-model sets the value of the bound variable in Vue), and then I change the value of the first select. The options for the second select then update, and in that second select I appear to be selected to the empty option. However, the bound variable still has the previously selected value. I'm assuming this is because updating the option values for the second select doesn't actually trigger an input or change event so v-model doesn't respond to anything. I suppose I could fix this with a watcher, but I was hoping for a more elegant solution.</p>
<p>Coded example is here: <a href="https://codepen.io/Slotheroo/pen/ajwNKO/" rel="noreferrer">https://codepen.io/Slotheroo/pen/ajwNKO/</a></p>
<p><strong>JS/Vue:</strong></p>
<pre><code>new Vue({
el: '#app',
data: {
selectedFruit: null,
selectedVariety: null,
fruits: {
"apples": [
{
name: "honeycrisp",
madeBy: "applebees",
},
{
name: "macintosh",
madeBy: "the steves",
},
{
name: "gala",
madeBy: "ac/dc",
},
{
name: "pink lady",
madeBy: "Alecia Beth Moore",
},
],
"pears": [
{
name: "d'anjou",
madeBy: "Maya D'Anjoulou",
},
{
name: "bartlett",
madeBy: "Anton Yelchin",
}
],
},
},
computed: {
fruitVarieties: function() {
return this.fruits[this.selectedFruit]
}
},
});
</code></pre>
<p><strong>HTML:</strong></p>
<pre><code><div id="app">
<div>
<select v-model="selectedFruit">
<option value=""></option>
<option v-for="fruitName in Object.keys(fruits)" :value ="fruitName">{{fruitName}}</option>
</select>
</div>
<select v-model="selectedVariety">
<option value=""></option>
<option v-for="fruitVariety in fruitVarieties" :value="fruitVariety">{{ fruitVariety.name }}</option>
</select>
<div>
</div>
<p>Selected variety: {{ selectedVariety }}</p>
</div>
</code></pre>
<p><strong>Steps to reproduce:</strong></p>
<ol>
<li>Select 'apples' in the first select</li>
<li>Select 'honeycrisp' in the second select</li>
<li>Select 'pears' or 'blank' in the first select</li>
</ol>
<p><strong>Hoped for result</strong></p>
<p>selectedVariety returns to null</p>
<p><strong>Actual result</strong></p>
<p>selectedVariety still equals honeycrisp</p>

spring Kafka integration testing with embedded Kafka
|
<p>I have spring boot application that had a consumer consumes from topic in one cluster and produces to another topic in different cluster.</p>
<p>Now I'm trying to write integration test case using spring embedded Kafka but having an issue <code>KafkaTemplate could not be registered. A bean with that name has already been defined in class path resource</code></p>
<p><strong>Consumer Class</strong></p>
<pre><code>@Service

}
}
</code></pre>
<p>In my Test cases I want to override <code>KafkaTemplate</code> so that when i call <code>kafkaConsumerService.professor</code> method in <code>Test</code> it should produce the data into embedded Kafka and i should validate it.</p>
<p><strong>Test config</strong></p>

<hr />
<p>And also can some one help me how to validate messages sent into embedded Kafka server?</p>

WPF ToggleButton IsChecked Trigger
|
<p>This is driving me batty. I have a simple WPF toggle button, with two triggers for IsChecked. One for the value being true, and the other for the value being false. It works fine when the button is not checked, my style for false is applied; however, the system never applies the style for when IsChecked is true. It always just uses the default blue chrome windows style. Any ideas?</p>
<pre><code><ToggleButton Content="Control 1" Width="200" Margin="0,0,0,10" Focusable="False">

Install OpenGL ES and compile code for android
|
<p>I've just started learning OpenGL ES on android (using <a href="https://rads.stackoverflow.com/amzn/click/com/1430226471" rel="noreferrer" rel="nofollow noreferrer">this book</a>) and came across an issue of adopting <a href="http://apress.com/book/view/9781430226475" rel="noreferrer">source</a> code from chapter 5 to existing methods of using jni in android (actually, it also concerns simply running a native GL app). I'm trying to compile the native code to get the .so lib and use it further in .apk archive. But compilation is not possible if certain libs are not present (which are GLES/gl.h, EGL/egl.h, GLES/gl.h, GLES/glext.h). </p>
<p>So the question is how do I install those libs (AFAIU, OpenGL ES and EGL installation) and compile the most trivial native code? (tutorials are highly admired).</p>
<p>Thanks in advance.</p>
<p>EDIT: I've tried the <a href="https://github.com/richq/glbuffer" rel="noreferrer">glbuffer</a> example as was suggested (slightly changed .mk file), but still no success. Compiler gives me the same result as before: </p>
<blockquote>
<p>ndk-build</p>
<p>Compile thumb: egl <= cube.c</p>
<p>/path/jni/cube.c:5:21: error: GLES/gl.h: No such file or directory // same message for glbuffer when gl.h is being included</p>
</blockquote>
<p>Here is the cube.c code:</p>
<pre><code>#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>
#include <GLES/gl.h>
#define FIXED_ONE 0x10000
#define one 1.0f
typedef unsigned char byte;
extern void jni_printf(char *format, ...);
// Cube static
GLfloat vertices[24] = { -one, -one, -one, one, -one,
-one, one, one, -one, -one, one, -one, -one, -one, one, one, -one, one, one, one, one, -one, one, one, };
static GLfloat colors[] = { 0, 0, 0, one, one, 0, 0, one, one, one, 0, one, 0, one, 0> , one, 0, 0, one, one, one, 0, one, one, one, one, one, one, 0, one, one, one, };
static byte indices[] = { 0, 4, 5, 0, 5, 1, 1, 5, 6, 1, 6, 2, 2, 6, 7, 2, 7, 3, 3, 7, 4, 3, 4, 0, 4, 7, 6, 4, 6, 5, 3, 0, 1, 3, 1, 2 };
void Cube_draw() {
glFrontFace(GL_CW);
glVertexPointer(3, GL_FLOAT, 0, vertices);
glColorPointer(4, GL_FLOAT, 0 , colors);
glDrawElements(GL_TRIANGLES, 36, GL_UNSIGNED_BYTE, indices); }
</code></pre>
<p>It's awfully trivial and not working, yet.</p>
<p>Android.mk:</p>
<pre><code>LOCAL_PATH := $(call my-dir)

Updating ModelState with model object
|
<p>The problem: How to update ModelState in posting+validation scenario.</p>
<p>I've got a simple form:</p>
<pre><code><%= Html.ValidationSummary() %>
<% using(Html.BeginForm())%>
<%{ %>
<%=Html.TextBox("m.Value") %>
<input type="submit" />
<%} %>
</code></pre>
<p>When user submits I want to validate input and in some circumstances I want to fix the error for user, letting him know that he made an error that is already fixed:</p>
<pre><code>[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(M m)
{
if (m.Value != "a")
{
ModelState.AddModelError("m.Value", "should be \"a\"");
m.Value = "a";
return View(m);
}
return View("About");
}
</code></pre>
<p>Well the problem is, MVC will simply ignore the model passed to the view and will re-render whatever the user typed -- and not my value ("a").
This happens, because the TextBox renderer checkes if there is a ModelState and if it's not null - ModelState's value is used. That value is of course the one user typed before posting.</p>
<p>Since I can't change the behaviour of TextBox renderer the only solution I found would be to update the ModelState by myself. The quick'n'dirty way is to (ab)use the DefaultModelBinder and override the method that assigns the values from forms to model by simply changing the assignment direction ;). Using DefaultModelBinder I don't have to parse the ids.
The following code (based on original implementation of DefaultModelBinder) is my solution to this:</p>
<pre><code>/// <summary>
/// Updates ModelState using values from <paramref name="order"/>
/// </summary>
/// <param name="order">Source</param>
/// <param name="prefix">Prefix used by Binder. Argument name in Action (if not explicitly specified).</param>
protected void UpdateModelState(object model, string prefix)
{
new ReversedBinder().BindModel(this.ControllerContext,
new ModelBindingContext()
{
Model = model,
ModelName = prefix,
ModelState = ModelState,
ModelType = model.GetType(),
ValueProvider = ValueProvider
});
}
private class ReversedBinder : DefaultModelBinder
{
protected override void BindProperty(ControllerContext controllerContext, ModelBindingContext bindingContext, System.ComponentModel.PropertyDescriptor propertyDescriptor)
{
string prefix = CreateSubPropertyName(bindingContext.ModelName, propertyDescriptor.Name);
object val = typeof(Controller)
.Assembly.GetType("System.Web.Mvc.DictionaryHelpers")
.GetMethod("DoesAnyKeyHavePrefix")
.MakeGenericMethod(typeof(ValueProviderResult))
.Invoke(null, new object[] { bindingContext.ValueProvider, prefix });
bool res = (bool)val;
if (res)
{
IModelBinder binder = new ReversedBinder();//this.Binders.GetBinder(propertyDescriptor.PropertyType);
object obj2 = propertyDescriptor.GetValue(bindingContext.Model);
ModelBindingContext context2 = new ModelBindingContext();
context2.Model = obj2;
context2.ModelName = prefix;
context2.ModelState = bindingContext.ModelState;
context2.ModelType = propertyDescriptor.PropertyType;
context2.ValueProvider = bindingContext.ValueProvider;
ModelBindingContext context = context2;
object obj3 = binder.BindModel(controllerContext, context);
if (bindingContext.ModelState.Keys.Contains<string>(prefix))
{
var prefixKey = bindingContext.ModelState.Keys.First<string>(x => x == prefix);
bindingContext.ModelState[prefixKey].Value
= new ValueProviderResult(obj2, obj2.ToString(),
bindingContext.ModelState[prefixKey].Value.Culture);
}
}
}
}
</code></pre>
<p>So the question remains: am I doing something extremely uncommon or am I missing something? If the former, then how could I implement such functionality in a better way (using existing MVC infrastructure)?</p>

How to subtract one dataframe from another?
|
<p>First, let me set the stage.</p>
<p>I start with a <code>pandas</code> dataframe <code>klmn</code>, that looks like this:</p>
<pre><code>In [15]: klmn
Out[15]:
K L M N
0 0 a -1.374201 35
1 0 b 1.415697 29
2 0 a 0.233841 18
3 0 b 1.550599 30
4 0 a -0.178370 63
5 0 b -1.235956 42
6 0 a 0.088046 2
7 0 b 0.074238 84
8 1 a 0.469924 44
9 1 b 1.231064 68
10 2 a -0.979462 73
11 2 b 0.322454 97
</code></pre>
<p>Next I split <code>klmn</code> into two dataframes, <code>klmn0</code> and <code>klmn1</code>, according to the value in the 'K' column:</p>
<pre><code>In [16]: k0 = klmn.groupby(klmn['K'] == 0)
In [17]: klmn0, klmn1 = [klmn.ix[k0.indices[tf]] for tf in (True, False)]
In [18]: klmn0, klmn1
Out[18]:
( K L M N
0 0 a -1.374201 35
1 0 b 1.415697 29
2 0 a 0.233841 18
3 0 b 1.550599 30
4 0 a -0.178370 63
5 0 b -1.235956 42
6 0 a 0.088046 2
7 0 b 0.074238 84,
K L M N
8 1 a 0.469924 44
9 1 b 1.231064 68
10 2 a -0.979462 73
11 2 b 0.322454 97)
</code></pre>
<p>Finally, I compute the mean of the <code>M</code> column in <code>klmn0</code>, grouped by the value in the <code>L</code> column:</p>
<pre><code>In [19]: m0 = klmn0.groupby('L')['M'].mean(); m0
Out[19]:
L
a -0.307671
b 0.451144
Name: M
</code></pre>
<p>Now, my question is, <strong><em>how can I subtract <code>m0</code> from the <code>M</code> column of the <code>klmn1</code> sub-dataframe, respecting the value in the <code>L</code> column?</em></strong> (By this I mean that <code>m0['a']</code> gets subtracted from the <code>M</code> column of each row in <code>klmn1</code> that has <code>'a'</code> in the <code>L</code> column, and likewise for <code>m0['b']</code>.)</p>
<p>One could imagine doing this in a way that replaces the the values in the <code>M</code> column of <code>klmn1</code> with the new values (after subtracting the value from <code>m0</code>). Alternatively, one could imagine doing this in a way that leaves <code>klmn1</code> unchanged, and instead produces a new dataframe <code>klmn11</code> with an updated <code>M</code> column. <em>I'm interested in both approaches.</em></p>

How to download a video while playing it, using ExoPlayer?

<h2>What I've tried</h2>
<p>I've tried reading on the docs, and got those links (by asking about it <a href="https://github.com/google/ExoPlayer/issues/4650" rel="noreferrer"><strong>here</strong></a> ) :</p>
<p><a href="https://medium.com/google-exoplayer/downloading-streams-6d259eec7f95" rel="noreferrer">https://medium.com/google-exoplayer/downloading-streams-6d259eec7f95</a>
<a href="https://medium.com/google-exoplayer/downloading-adaptive-streams-37191f9776e" rel="noreferrer">https://medium.com/google-exoplayer/downloading-adaptive-streams-37191f9776e</a></p>
<p>So sadly, currently the only solution I can come up with, is to download the file on another thread, which will cause the device to have 2 connections to it, thus using twice the bandwidth.</p>
<h2>The questions</h2>
<ol>
<li>How can I use ExoPlayer to play a video file, while also downloading it to some filepath ?</li>
<li>Is there a way to enable a caching mechanism (which uses the disk) on ExoPlayer to be activated for the exact same purpose?</li>
</ol>
<p>Note: To make it clear. I do not want to download the file and only then play it. </p>
<hr>
<p>EDIT: I've found a way to get&use the file from the API's cache (wrote about it <a href="https://stackoverflow.com/a/53704530/878126"><strong>here</strong></a>), but it appears that this is considered as unsafe (written <a href="https://github.com/google/ExoPlayer/issues/5569#issuecomment-470081053" rel="noreferrer"><strong>here</strong></a>). </p>
<p>So, given the simple cache mechanism that the API of ExoPlayer supports, my current questions are: </p>
<ol>
<li>If a file was cached, how can I use it in a safe manner?</li>
<li>If a file was partially cached (meaning we've downloaded a part of it), how can I continue preparing it (without actually playing it or waiting for the whole playback to finish) till I can use it (in a safe manner of course) ? </li>
</ol>
<p>I've made a Github repository for this <a href="https://github.com/AndroidDeveloperLB/ExoPlayerCacheSample" rel="noreferrer"><strong>here</strong></a>. You can try it out.</p>

Using GraphServiceClient to get refresh tokens when authenticating using UserPasswordCredential in AuthenticationContext
|
<p>Sincere apologies if I miss something from this post, as I'm at my wits end after reading around for hours.</p>
<p>I'm attempting to write a back-end service (Windows) which will connect to the MS Graph API via Azure AD. I'm using C# to knock up a proof-of-concept but have run into numerous issues with the MS docs, blogs etc. being fairly convoluted and poor quality. They all seem to assume that the consumers of their API are front-end desktop or browser based apps.</p>
<p>Anyway, having managed to get connected to the Graph using the UserPasswordCredential for the service account, I receive a token in the AuthenticationContext response, but no refresh token information. MSDN suggests that the method <em>may</em> return refresh info, but hey ho, it may not. </p>
<p>Furthermore, reading (or attempting to read) this blog post on ADAL 3 (from 2015): </p>
<p><a href="http://www.cloudidentity.com/blog/2015/08/13/adal-3-didnt-return-refresh-tokens-for-5-months-and-nobody-noticed/" rel="noreferrer">http://www.cloudidentity.com/blog/2015/08/13/adal-3-didnt-return-refresh-tokens-for-5-months-and-nobody-noticed/</a></p>
<p>Left me confused in terms of how the refresh now works. The article seems to be suggesting that almost magically the tokens are refreshed in the cache for you, but after testing with my POC this is not the case.</p>
<p>I also came across this article from MS which seemed to nail it in the title:</p>
<p><a href="https://msdn.microsoft.com/en-us/office/office365/howto/building-service-apps-in-office-365" rel="noreferrer">https://msdn.microsoft.com/en-us/office/office365/howto/building-service-apps-in-office-365</a></p>
<p>However, goes off on a bit of a tangent requiring you to register apps, jump through pop-up hoops permitting access etc. etc.</p>
<p>Since I have my sample running, I've tried scheduling a re-auth to hopefully get a new token 50mins after getting the initial token (which lasts 60mins) however I just get the same token. This means at 60mins 1sec any calls via the client throw an exception (ServiceException where I have to examine the text inside to see the token expiry related info). It doesn't make sense to me to not be able to re-auth and refresh the token to carry on with a more "seamless" use of the client. </p>
<p>Here's a stripped down sample version of my code:</p>
<pre><code>namespace O365GraphTest
{
using Microsoft.Graph;
using Microsoft.IdentityModel.Clients.ActiveDirectory;

{
var tenant = "mytenant.onmicrosoft.com";
var username = $"test.user@{tenant}";
var password = "fooooooo";
var token = await GetAccessToken(username, password, tenant);
var client = GetClient(token)
// Example of graph call
var skusResult = await client.SubscribedSkus.Request().GetAsync();
}
private static async Task<string> GetAccessToken(string username, string password, string tenant = null)
{

var authContext = new AuthenticationContext(authString);
var creds = new UserPasswordCredential(username, password);
// Generic client ID
var clientId = "1950a258-227b-4e31-a9cf-717495945fc2";
var resource = "https://graph.microsoft.com";
// NOTE: There's no refresh information here, and re-authing for a token pre-expiry doesn't give a new token.
var authenticationResult = await authContext.AcquireTokenAsync(resource, clientId, creds);
return authenticationResult.AccessToken;
}
private static GraphServiceClient GetClient(string accessToken, IHttpProvider provider = null)
{
var delegateAuthProvider = new DelegateAuthenticationProvider((requestMessage) =>
{
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
return Task.FromResult(0);
});
var graphClient = new GraphServiceClient(delegateAuthProvider, provider ?? HttpProvider);
return graphClient;
}
}
}
</code></pre>
<p>If anyone can help me with this, without just saying "do it a different way" I'd be most grateful as there seems to be little discussion about this online (Freenode, IRC) and the blogs are old, the docs on MSDN terse and for specific previous versions of the library etc. e.g. </p>
<p><code>Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext.AcquireTokenAsync</code> </p>
<p>the refresh method for the AuthenticationContext class has now been removed.</p>
<p>Thanks for any advice.</p>
<p>Peter</p>
<p><strong>UPDATE</strong></p>
<p>Firstly apologies an thanks to @Fei Xue who answered my question, but I couldn't get the gist of what they were saying to begin with.</p>
<p>After chatting with Fei Xue, it does seem that if you keep the auth context around you can use the AcquireTokenSilentAsync to get new tokens going forward, you don't need to handle scheduling any refresh/reauth etc. Just bake in a check in the delegate handler (as to which method you're calling) that is part of getting the client.</p>
<p>Here's the updated version of my sample code that I've tested and it seems to work.</p>

Accessing Coordinates in a nested geojson file to draw polygons with Google Maps API v3
|
<p>I am having a real pain of trying to draw multiple polygons from a geojson file. Below I have pasted a sample of the geojson file and the javascript used to access it. It seems the main problem I am running into is that I cannot get into that array of coordinates nested in each record as it either returns the error that "coordinates" is undefined or that there is no method "setMap" for undefined. I have been able to return other nested aspects of a similar JSON file (this is a test file, the real one actually has data, just trying to get the polygon drawing here), but getting those coordinates is not working. I am not a javascript master so I can't tell where the code is failing to make the proper access.</p>
<p>thanks in advance.</p>
<p>the json data looks like this:</p>

Angular 6 StaticInjectorError (Platform: core) No provider for
|
<p>I have a project with a angular version of 4. *. \ *.
I tried to update the project to 6 angular versions.
I fixed all the errors that the compiler told me when I build a prod. There were a lot of them.
Now the project compiles without errors, but it does not work in the browser.
And now I'm stuck. Can someone help me with this problem?<br>
I think this is somehow connected with lazy loading, but I have not been able to find a solution for a long time.<br>
Added a code that can help in the answer. If you need something else, tell me.

how to code json array without array name?
|
<p>I'm new to JSON android java eclipse. I am doing a listview with images and parsing json array. I followed this tutorial: <a href="http://www.wingnity.com/blog/android-json-parsing-and-image-loading-tutorial/" rel="nofollow">http://www.wingnity.com/blog/android-json-parsing-and-image-loading-tutorial/</a> . In that tutorial, their JSON array contains the array name.However, mine doesn't contain the array name. So my question is how to code JSON Array without the array name? </p>
<p>Below is my JSON code. </p>
<pre><code>[
{ "event_id": "EV00000001",
"event_title": "Movie 1",
},
{
"event_id": "EV00000002",
"event_title": "Movie2",
}
]
</code></pre>
<p>Below is my JSON coding for parsing the JSON.</p>
<pre><code> protected Boolean doInBackground(String... urls) {
try {
HttpGet httppost = new HttpGet(urls[0]);
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(httppost);
// StatusLine stat = response.getStatusLine();
int status = response.getStatusLine().getStatusCode();
if (status == 200) {
HttpEntity entity = response.getEntity();
String data = EntityUtils.toString(entity);
JSONObject jsono = new JSONObject(data);
JSONArray jarray = jsono.getJSONArray("actors");
for (int i = 0; i < jarray.length(); i++) {
JSONObject object = jarray.getJSONObject(i);
Events event = new Events();
event.setevent_title(object.getString("event_title"));
eventList.add(event);
}
return true;
}
//------------------>>
} catch (ParseException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return false;
}
</code></pre>
<p>What am i suppose to do?</p>
<p>This problem is solved. Thus, i will be posting the correct code. </p>
<pre><code>protected Boolean doInBackground(String... urls) {

Could we destroy/invalidate JWT token in Asp.NET Core?
|
<p>I use ASP.NET Core & ASP.NET core Identity to generate a JWT token.</p>
<p>On the client-side, my React (SPA) app calls API to create the token then include <code>Authorization: Bearer</code> <code>token from API</code> in subrequests.</p>
<p>When I want to logout, how can I immediately invalidate the token on the server-side?</p>
<p>Currently, I just delete the <code>bear</code> token on the client-side and not included in the next request?</p>

c# - How to use DateTimeOffset in MongoDB

<pre><code>public class ScheduledEvent : Event
{
public DateTimeOffset StartDateTime { get; set; }
}
</code></pre>
<p>StartDateTime = 5/27/2013 2:09:00 AM +00:00 representing 05/26/2013 07:09 PM PST</p>
<p>What's recorded in MongoDB:</p>
<pre><code>db.ScheduledEvent.find().toArray()[
{
"_id": BinData(3, "ZE2p31dh00qb6kglsgHgAA=="),

],
"StartDateTime": [
NumberLong("635052173400000000"),
0
]
}
]
</code></pre>
<hr />
<p>I realize that StartDateTime is stored as Ticks in MongoDB.</p>
<pre><code>var dateMarker = DateTimeOffset.UtcNow;
var nextDay = dateMarker.AddDays(1);
</code></pre>
<p>This query does not work:</p>
<pre><code>var today = EventRepoistory
.All()
.Where(z => z.StartDateTime >= dateMarker
&& z.StartDateTime < nextDay)
.OrderByDescending(z => z.StartDateTime)
.ToList();
</code></pre>
<p>I have added a query display to the Mongo C# driver which shows the following query:</p>
<pre><code>{ "$query" : { "StartDateTime" : { "$gte" : [NumberLong("635052168609734070"), 0], "$lt" : [NumberLong("635053032609734070"), 0] } }, "$orderby" : { "StartDateTime" : -1 } }
</code></pre>
<blockquote>
<p><code>Lower bound = 6350521 68609734070</code></p>
</blockquote>
<blockquote>
<p><code>Server = 6350521 73400000000</code></p>
</blockquote>
<blockquote>
<p><code>Upper bound = 6350530 32609734070</code></p>
</blockquote>
<p><strong>Question: Why this MongoDB query doesn't return anything?</strong></p>
<pre><code>db.ScheduledEvent.find({
"$query": {
"StartDateTime": {
"$gte": [NumberLong("635052168609734070"), 0],
"$lt": [NumberLong("635053032609734070"), 0]
}
},
"$orderby": {
"StartDateTime": -1
}
})
</code></pre>
<p>I have researched about this topic and I found this solution :
<a href="https://stackoverflow.com/questions/10480127/mongodb-and-datetimeoffset-type">MongoDB and DateTimeOffset type</a></p>
<p>But it seams that LINQ provider is doing what it's supposed to?</p>
<hr />
<p>I have also tried code:</p>
<pre><code>db.ScheduledEvent.find({
"StartDateTime": {
"$gte": [NumberLong("1"), 0]
}
})
</code></pre>
<p>But it doesn't return any result.</p>

JNDI Name binding in JBOSS 5.1.0 Beta

<p>I am following the MasteringEJB4thEdition book, which I downloaded from The Server Site website.</p>
<p>There is a simple example of HelloBean, which works perfectly with GlassFish V3 app server. The same example when deployed on JBOSS fails because of JNDI name lookup.</p>
<p>Is there any rule how the JNDI lookup names in JBOSS are decided if we don't provide any ? I found while googling that it is "ear-file-name/Bean-class-name/remote" but it doesn't work for me.</p>

Can't Build NetBeans/Ant Project
|
<p>I have inherited a project originally written in NetBeans using Ant to build. I am an Eclipse user and have used Ant but do not completely understand the NetBeans specific way of using Ant. I know it uses a <code>build-impl.xml</code> file (imported into the <code>build.xml</code>), but am at a loss as to how that file is <code>generated/updated</code> by the IDE.</p>
<p>I made some minor changes to a couple of classes and want to build a jar. I tried running the <code>"clean"</code> and <code>"jar"</code> targets in Eclipse from both the <code>build.xml</code> and <code>build-impl.xml</code> but get the following errors:</p>
<pre><code>BUILD FAILED
C:\Devel\Projects\MyProject\nbproject\build-impl.xml:661: The following error occurred while executing this line:

<p>I have no idea what these two targets are about and why they're failing. I downloaded NetBeans7 hoping that building it there would succeed, but get the same errors.</p>
<p>Can I safely remove these targets from my build? Do I need to update the project.properties file?</p>
<p>Any help getting this to build is appreciated.</p>

Accessing class variables
|
<p>It's the first time I use OOP with PHP 5.. so this is my problem..</p>
<p>I have a file <code>disp.php</code> that contains a class named class disp (model in MVC)</p>
<pre><code><?php
class disp{
public $n_pages;
public $current_page;
private $cmd2;
/***************SQL command generator*******************/
private function getCmd2($cmd1,$id,$first_entry,$perpage,$tri){
$cmd2=str_replace('COUNT(*)','*',$cmd1);
$cmd2=$cmd2.' ORDER BY '.$id.' '.$tri.' LIMIT '.$first_entry.','.$perpage;
return $cmd2;
}
/********************Items display******************/
function dispItems($cmd1,$id,$perpage,$tri){
require('global/connection.inc.php');
try{
foreach($pdo->query($cmd1)as $r){
$n_pages=ceil($r[0]/$perpage);
if (isset ($_GET['pg'])){
$current_page=intval($_GET['pg']);
if ($current_page>$n_pages){
$current_page=$n_pages;
}
if ($current_page<=0){
$current_page=1;
}
}
else{
$current_page=1;
$_GET['pg']=1;
}
}
$i=1;
$first_entry=($current_page-1)*$perpage;
$objet=new disp();
$cmd2=$objet->getCmd2($cmd1,$id,$first_entry,$perpage,$tri);
$data=array();
$i=0;
foreach($pdo->query($cmd2) as $r){
$data[$i]=$r;
$i++;
}
return $data;
}catch(PDOException $e){}
}
}
</code></pre>
<p>this is the file <code>news.php</code> (controller in MVC):</p>
<pre><code>require MODELS_DIR.'disp.php';
$objet=new disp();
$news=$objet->dispItems('SELECT COUNT(*) FROM tbl_nouveautes','ID_EVENT',10,'DESC');
$c_page=$objet->$current_page;
$n_pages= $objet->$n_pages;
require VIEWS_DIR.'disp-news.php';
</code></pre>
<p>in this code, I created an object (objet) of the type disp... I want to use the variables declared in the function <code>dispItems</code>, (<code>$n_pages</code> and <code>$current_page</code>) in the view (<code>disp-news.php</code>)</p>
<p>so I think that the class variables are the same variables in the function <code>dispItems()</code>... but when trying to access them from the controller ...using object. it shows me a error :</p>
<p>See:</p>
<pre><code>Notice: Undefined variable: n_pages in C:\Program Files\EasyPHP-5.3.6.1\www\example\admin\global\news.php on line 14
Fatal error: Cannot access empty property in C:\Program Files\EasyPHP-5.3.6.1\www\example\admin\global\news.php on line 14
</code></pre>
<p>Inspite of <code>$n_pages</code> and <code>$current_pages</code> being public in the class disp</p>
<p>thank you in advance</p>

unable to download artifact from nexus repo
|
<p>I am using a nexus repo in a linux system which downloads missing artifacts for me in my windows system when i build my project, by using:</p>
<pre><code>mvn install command
</code></pre>
<p>The artifacts are downloaded by my nexus repo from a remote repo which is mapped to the nexus repo.</p>
<p>This connection between the nexus repo set up in linux system and the remote repo used to work earlier and thus I used to get all the required artifacts for my maven build automatically when i used to build my project using maven.</p>
<p>But due to some reasons the nexus repo in linux is not downloading artifacts from the remote repo.I want this connection to happen so that i could get the required artifact say, tomcat-catalina-7.0.16.jar,downloaded from the remote repo.</p>
<p>I am new to nexus..so may be I would not have been able to explain my problem properly or would have been technically unsound in my question.But I eagerly want to solve my problem.So please if any one could help, please do.</p>
<p>hi, i checked nexus.log and found the following exception while mvn install command was running and when nexus was trying to download the missing tomcat-catalina-7.0.16.jar artifact from the remote repo:</p>

How to merge multiple datatables (every datatable return one row) in one row
|
<p>I have multiple data tables : i want to merge them (My <strong>P.K : emp_num</strong>)</p>
<pre><code>var tblEmp_data = new DataTable();//one row
var tblEmp_time = new DataTable();//one row
var tbl_emp_mission = new DataTable();//one row
tblEmp_data = GetEmpInfo(empNum);
tblEmp_time = GetEmpTime(empNum, start_period, end_period);
tbl_emp_mission = GetEmpMission(empNum, start_period, end_period);
tblEmp_data.Merge(tblEmp_time, false, MissingSchemaAction.Add);
tblEmp_data.AcceptChanges();
tblEmp_data.Merge(tbl_emp_mission, false, MissingSchemaAction.Add);
tblEmp_data.AcceptChanges();
</code></pre>
<hr />
<p>Now i get the data on multiple rows rather than one row !
I want the data on one row ? how to do this ?</p>
<hr />
<p>Note: i want all the columns allow null except the primary key so i avoid this exception :</p>
<pre><code>failed to enable constraints. one or more rows contain values violating non-null, unique, or foreign-key constraints
</code></pre>
<hr />
<h1>Edited:</h1>
<p>The third table which cause the problem:</p>

Core Data nested managed object contexts and frequent deadlocks / freezes
|
<p><strong>I have a problem that is almost identical to the problem described by this person here, but it hasn't get answered:</strong></p>
<p><a href="http://www.cocoabuilder.com/archive/cocoa/312683-core-data-nested-managed-object-contexts-and-frequent-deadlocks.html#312683" rel="noreferrer">http://www.cocoabuilder.com/archive/cocoa/312683-core-data-nested-managed-object-contexts-and-frequent-deadlocks.html#312683</a></p>
<p><strong>Here is the problem:</strong></p>
<p>I have a parent MOC setup with NSPrivateQueueConcurrencyType and a persistent store coordinator set, it has a child MOC setup with NSMainQueueConcurrencyType. The idea being most of the long hard work and saves can be done on the private MOC freeing the main thread from blocking the UI. Unfortunately I seem to be running into a couple of situations that cause deadlocks.</p>
<p>If the child MOC (on the main thread) is performing a fetch with NSFetchedResultsController the parent context is sent an -executeFetchRequest: it can create a deadlock. Both operations are done within the context of a performBlock: for their respective MOCs although the docs seem to indicate that using a main thread concurrency type MOC on the main thread without performBlock: is fine.</p>
<p>It appears that the private queue is waiting on the PSCs lock which the child context on the main thread has already locked. It appears that the child context (while holding the PSCs lock) is trying to dispatch_sync to the parent context and thus they are both waiting for each other.</p>
<p>Is PriveQueue -> MainQueue a supported configuration? It seems most people still have the parent context on the main thread.</p>
<p>The main thread looks like this:</p>

<p><strong>He also writes this:</strong></p>
<p>I'm starting to think the problem is with NSFetchedResultsController which is always stuck at performFetch: when these deadlocks occur. Most of the time it will be stuck trying to fault in an object as a result of asking for it's section name. As a test I tried to reproduce what the FRC does and performed the executeFetchRequest: and then iterated through the results asking each object for it's section name. And this doesn't cause a deadlock. If I leave the FRC to do performFetch: after I do my test it will still deadlock there. I'm 99% sure that the FRC has a synchronization problem with nested contexts.</p>
<p><strong>Question: Does anybody know why this problem occurs? Do you know how to solve it? Is this a bug?</strong></p>

How do I get didReadData within GCDAsyncSocket execute within the current RunLoop?
|
<p>I'm trying to get a simple example working with GCDAsyncSocket, and am discovering that I'm missing certain bits of understanding and hope you fine people can help explain this.</p>
<p>I've setup the GCDAsyncSocket stuff below:</p>
<pre><code>dispatch_queue_t mainQueue = dispatch_get_main_queue();
asyncSocket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:mainQueue];
NSString *host = @"192.168.169.132";
uint16_t port = 2112;
DDLogInfo(@"Connecting to \"%@\" on port %hu...", host, port);
self.viewController.label.text = @"Connecting...";
NSError *error = nil;
if (![asyncSocket connectToHost:host onPort:port withTimeout:5.0 error:&error])
{
DDLogError(@"Error connecting: %@", error);
self.viewController.label.text = @"Oops";
}
else
{
DDLogVerbose(@"Connecting...");
}
- (void)socket:(GCDAsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port
{
DDLogInfo(@"socket:%p didConnectToHost:%@ port:%hu", sock, host, port);
self.viewController.label.text = @"Connected";
// We're just going to send a test string to the server.
NSString *myStr = @"testing...123...\r\n";
NSData *myData = [myStr dataUsingEncoding:NSUTF8StringEncoding];
[asyncSocket writeData:myData withTimeout:5.0 tag:0];
}
</code></pre>
<p>And can see my socket test server app receive the string </p>
<blockquote>
<p>"testing...123...\r\n"</p>
</blockquote>
<p>But when I then have my socket test server send a string back, I naively expected the <strong><em>didReadData</em></strong> delegate to execute</p>
<pre><code>- (void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag
</code></pre>
<p>Yet the cold hard reality forced me learn that until I call</p>
<pre><code>[asyncSocket readDataWithTimeout:5.0 tag:0];
</code></pre>
<p>... the <strong><em>didReadData</em></strong> delegate will not get called.</p>
<p>OK, that's fine. I get it.</p>
<p>Reading up on <a href="http://code.google.com/p/cocoaasyncsocket/wiki/Reference_AsyncSocket#RunLoop_Configuration" rel="noreferrer">the documentation</a> some more it clearly states that </p>
<blockquote>
<p>AsyncSocket is a RunLoop based TCP socket library.</p>
</blockquote>
<p>So now I'm looking at this <strong><em>RunLoop</em></strong> thing, which in my view is like the <a href="http://en.wikipedia.org/wiki/Message_loop_in_Microsoft_Windows" rel="noreferrer">Message loop in Microsoft Windows</a>. Being that iOS is an event/msg driven architecture (just like Win32), then the default main thread I'm currently in obviously has it's own msg loop to handle events.</p>
<p>My confusion is now having iOS RunLoop seem like some separate entity to have to work with in getting GCDAsyncSocket to work properly.</p>
<p>When it states that its default set of run loop mode is NSDefaultRunLoopMode, which is in the main thread.</p>
<p>Confused yet?</p>
<p>So under Win32 my comm event handling code would look like this:</p>
<pre><code>while( sCOMport.hCOMport != INVALID_HANDLE_VALUE ) // ...while the COM port is open...
{
// Wait for an event to occur on the port.
WaitCommEvent( sCOMport.hCOMport, &dwCommStatus, NULL );
</code></pre>
<p>It would of course be in its own thread (haven't gotten there yet using GCDAsyncSocket), but that would be its own "RunLoop" in a way.</p>
<p>How do I do the same using <strong>GCDAsyncSocket</strong> so that I'm not stuck in some polling loop filling the queue with <strong>[asyncSocket readDataWithTimeout]</strong> calls?</p>
<p>I feel we need better examples in using this library.</p>

jQuery mobile data-rel="back" link causing wrong events to be fired
|
<p>Have a look at the <a href="http://dl.dropbox.com/u/16705233/data-rel-back.html" rel="nofollow">test-case</a></p>
<p>When you open the link, <code>pagebeforeshow</code> for <em>page 1</em> is fired. When you click the link to go to <em>page 2</em>, <code>pagebeforeshow</code> for <em>page 2</em> is fired. So far, so good.</p>
<p>If you then use the left button (<code>data-rel="back"</code>) to go back, excess events are fired. Using the right button instead (direct link to <em>page 1</em>) does what I'd expect, namely, only <code>pagebeforeshow</code> for <em>page 1</em> gets fired.</p>
<p><code>pagebeforeshow</code> can also be replaced with <code>pageshow</code>, doesn't matter. What's happening here?</p>
<p>(Tested in up-2-date Chrome)</p>

How to wait for subscriptions inside a for loop to complete before proceeding
|
<p>I have a subscription inside of a for loop that fetches JSON data as a series of "category data" from an external source, then filters that data based on the users current location. What I need is to wait for all of the subscriptions to complete, and then and only then can my app proceed. Right now, it does not wait for all of the subscriptions to complete, it only completes a few, and then proceeds, while the other subscriptions continue in the background.</p>
<p>I've tried the following "brute force" method, where i know a certain number of categories will be added to the filtered array, and it works, but I don't know how to make it work for any situation.</p>
<p>Here's my code:</p>
<pre><code>getMultipleCategoryData(categoryIds: string[]) {
for (let i = 0; i < this.waypointIds.length; i++) {
//after user selects their categories, its added to waypointNames, and occurences() gets the # of occurences of each waypoint name
let occurences = this.occurences(this.waypointNames[i], this.waypointNames);
this.categoryApi.getCategoryData(this.waypointIds[i]).toPromise().then(data => {
let filteredLocs = data.locations.filter(loc => this.distanceTo(loc, this.hbLoc) < MAX_RADIUS);
let foundLocs = [];
//fill filteredLocs with first n, n = occurences, entries of data
for (let n = 0; n < occurences; n++) {
if (filteredLocs[n] != undefined) {
foundLocs[n] = filteredLocs[n];
}
}
//find locations closest to hbLoc (users current location), and add them to waypoints array
for (let j = 0; j < foundLocs.length; j++) {
for (let k = 0; k < filteredLocs.length; k++) {
if (this.distanceTo(this.hbLoc, filteredLocs[k]) < this.distanceTo(this.hbLoc, foundLocs[j]) && foundLocs.indexOf(filteredLocs[k]) < 0) {
foundLocs[j] = filteredLocs[k];
}
}
}
if (foundLocs.length > 0 && foundLocs.indexOf(undefined) < 0) {
for (let m = 0; m < foundLocs.length; m++) {
this.waypointLocs.push(foundLocs[m]);
}
}
}).then(() => {
//this hardcoded, brute force method works, but i'd need it to be more elegant and dynamic
if (this.waypointLocs.length >= 5) {
let params = { waypointLocs: this.waypointLocs, hbLoc: this.hbLoc };
this.navCtrl.push(MapPage, params);
}
});
}
}
</code></pre>
<p>And the categoryApi.getCategoryData method:</p>
<pre><code>getCategoryData(categoryId): Observable<any> {
// don't have data yet
return this.http.get(`${this.baseUrl}/category-data/${categoryId}.json`)
.map(response => {
this.categoryData[categoryId] = response.json();
this.currentCategory = this.categoryData[categoryId];
return this.currentCategory;
});
}
</code></pre>
<p>Everything is working fine except waiting for the subscriptions to complete, I'd really like a way to determine when all of the subscriptions have completed. Any help is appreciated!</p>

Why doesn't blur(0) remove all text blur in Webkit/Chrome on retina screens?
|
<p>I recently came across an odd behaviour in Webkit browsers (under OSX at least) which took far longer to resolve than I would like!</p>
<p>Essentially: setting <code>filter: blur(0)</code> (or the vendor-specific <code>-webkit-filter</code>) on an element should mean that no form of blur is applied to the element.</p>
<p>However Webkit still blurs the element when either <code>blur(0)</code> or zeroing with a unit specified (ie: <code>blur(0px)</code>) is assigned to it.</p>
<p>I've knocked together a quick Fiddle here to demonstrate: <a href="http://jsfiddle.net/f9rBE/" rel="nofollow noreferrer">http://jsfiddle.net/f9rBE/</a></p>
<p>This shows three identical divs containing text (no custom fonts):</p>
<pre class="lang-html prettyprint-override"><code><div class="no-blur">
<p><strong>This has absolutely nothing assigned</strong></p>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam facilisis orci in quam venenatis, in tempus ipsum sagittis. Suspendisse potenti. Donec ullamcorper lacus vel odio accumsan, vel aliquam libero tempor. Praesent nec libero venenatis, ultrices arcu non, luctus quam. Morbi scelerisque sit amet turpis sit amet tincidunt. Praesent semper erat non purus pretium consequat. Aenean et iaculis turpis. Curabitur diam tellus, consectetur non massa et, commodo venenatis metus.</p>
</div>
</code></pre>
<p>One has no style at all assigned to it whilst the other two have <code>blur(0)</code> and <code>blur(0px)</code>:</p>
<pre class="lang-css prettyprint-override"><code>.no-blur{}
.zero-px-blur{
-webkit-filter: blur(0px);
-moz-filter: blur(0px);
-o-filter: blur(0px);
-ms-filter: blur(0px);
filter: blur(0px);
}
.zero-blur{
-webkit-filter: blur(0);
-moz-filter: blur(0);
-o-filter: blur(0);
-ms-filter: blur(0);
filter: blur(0);
}
</code></pre>
<p>If you take a look in Safari or Chrome, the bottom two are blurred:</p>
<p><img src="https://i.stack.imgur.com/Yh58U.png" alt="enter image description here"></p>
<p>A few things worth noting:</p>
<ul>
<li>This unintentional blurring also occurs in Safari on iOS7 devices (both iPhones and iPads);</li>
<li>It also occurs on Chrome and Safari under OSX;</li>
<li>It doesn't appear to occur under Chrome and Safari on non-retina Apple hardware;</li>
<li>It doesn't happen under FireFox in OSX.</li>
</ul>
<p>Of course, <code>filter: blur</code> isn't supported at all in Firefox just yet so it's hard to tell whether the behaviour I'm seeing is intentional/expected behaviour, or whether this is a bug in Webkit?</p>
<p>I eventually came to the conclusion that using <code>blur(none)</code> instead had the desired effect (ie: removed all blur effects), but I'm confused as to why using zero doesn't have the same effect given that in other filter examples (eg: <code>filter: grayscale</code>) can be reset simply using zero rather than the none keyword.</p>
<p>Why is this?</p>

<p>I need something like that :</p>
<p><img src="https://i.stack.imgur.com/zy8Aa.jpg" alt="enter image description here"></p>
<p>======================UPDATE=========================</p>
<p>I have add the click event as a result of domi27 recomendation.
Kindly review the freemarker updates.
I have added a java script method that uses :<a href="http://arshaw.com/fullcalendar/docs/event_data/removeEvents/" rel="nofollow noreferrer">http://arshaw.com/fullcalendar/docs/event_data/removeEvents/</a></p>
<p>The new JS method : </p>
<pre><code> $('#calendar').fullCalendar('removeEvents', 1);
</code></pre>
<p>This method works perfectly with the events that was initially loaded from the controller.
However,whenever I try to use the same method to remove the new events I have just added,Nothing happens.
When I fire the "select event" for the new event I created ,I get for its id"undefined".</p>
<p>As I've mentiond on my freemarker,that are the lines I use to build the new event object that I aappend to the list.</p>
<pre><code>var newVacation = {id:'133',title:'title',start:start,url: 'title'};
resourceVacation.push(newVacation);
</code></pre>
<p>When I debug my script,I observe a difference among the objects loaded from the controller and the new object I created when the user adds a new event.</p>
<p>Here is the old object I got from the controller when I initiated the calendar:
<img src="https://i.stack.imgur.com/8pjIG.jpg" alt="enter image description here"></p>
<p>Here is the new Object I got after I insert the new event:</p>

<p>I'm using MySqlDB</p>
<h2>Note:-</h2>
<p>All migrations are applied and Db is in right state</p>
<p><strong>Update</strong></p>
<p>Issue is related to MYSQL madating columns to be available in select statements when its creating a Having clause . Refer to -
<a href="https://stackoverflow.com/questions/36105812/unknown-column-in-having-clause">Unknown column in 'having clause'</a>.
Django in this instance is not adding as the column to be selected. hence the error.
I need to some how find a way to add this in the select clause with other params.</p>

List of objects not binding to the model on post back in asp.net mvc 4
|
<p>In my my MVC 4 application, I have a Customer which can have multiple sites and can subscribe to multiple service packages. A short version of my view model looks like below </p>
<pre><code>public class SubscriptionModel
{
public int MemberId { get; set; }
public List<SitePackage> SitePackges { get; set; }
public SubscriptionModel()
{
SitePackges=new List<SitePackage>();
}
}
public class SitePackage
{
public int SiteId { get; set; }
public List<PackageDisplayItem> LstPackageDisplayItems { get; set; }
public SitePackage()
{
LstPackageDisplayItems=new List<PackageDisplayItem>();
}
}
public class PackageDisplayItem
{
public int PackageId { get; set; }
[Display(Name = "Package")]
public string Name { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Start Date")]
public DateTime? StartDate { get; set; }
}
</code></pre>
<p>In my controller I fill in the model and then pass to View Model for rendering</p>
<pre><code> @using (@Html.BeginForm("CalculateCost", "HelpDesk", FormMethod.Post, new { @class = "form", id = "PackageSubscription", name = "PackageSubscription" }))
{
@Html.HiddenFor(x=>x.MemberId)
<table class="table">
@foreach (var site in Model.SitePackges)
{
<input name="SiteId" id="SiteId" type="hidden" value=@site.SiteId.ToString() />
<tr><td class="col-sm-3">@site.SiteId</td></tr>
<tr>
<th class="col-sm-3">
Name
</th>
<th class="col-sm-2">
Start Date
</th>
</tr>
@Html.Partial("_Packages",site.LstPackageDisplayItems)
}
</code></pre>
<p>My partial view is like</p>
<pre><code>@model List<PackageDisplayItem>
@for (int i = 0; i < Model.Count; i++)
{
@Html.HiddenFor(x => x[i].PackageId)
<tr id="@Model[i].PackageId">
<td>
@Html.DisplayFor(x => x[i].Name)
</td>
<td>
@Html.TextBoxFor(x => x[i].StartDate, "{0:d MMM yyyy}", new { @class = "jquery_datepicker form-control", autocomplete = "off" })
</td>
</tr>
}
</code></pre>
<p>Every thing renders fine but on the form post the model binder is not binding <code>SitePackges</code> list and its count is always 0. My controller has the following signatures.</p>
<pre><code>[HttpPost]
public ActionResult CalculateCost(SubscriptionModel subscriptionModel )
{
var receivedModel = subscriptionModel;
}
</code></pre>
<p>Not sure if the model I have designed is the best approach to handle this requirement (The requirement is to show a single site and just below it show the packages and then 2nd site and packages and so on). The controls seems to have unique indexes generated.</p>
<p>Jquery Post</p>
<pre><code>function SubmitForm() {
console.log($("#PackageSubscription").serialize());
$.ajax({
url: '/HelpDesk/CalculateCost',
cache: false,
dataType: 'json',
data: $("#PackageSubscription").serialize(),
type: 'POST',
success: function (data) {
}
});
</code></pre>
<p>}</p>
<p>I will appreciate any help. thanks</p>

Stop form refreshing page on submit

<p>How would I go about preventing the page from refreshing when pressing the send button without any data in the fields?</p>
<p>The validation is setup working fine, all fields go red but then the page is immediately refreshed. My knowledge of JS is relatively basic.</p>
<p>In particular I think the <code>processForm()</code> function at the bottom is 'bad'.</p>
<p><strong>HTML</strong></p>

Angular: focusout event not working with div tag

<p>I have a div tag which works as select box with multi select feature.</p>

<p></p>
<p>It looks like this <a href="https://i.stack.imgur.com/c55k2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/c55k2.png" alt="Multiselect"></a>What I'm trying is, when I click outside the div it should get disabled, so I'm trying with focusout event and in disableSelect() method I'm just making a value false. But focusout event is not working. Does div doesn't support focusout? Or is there any other way to disable?</p>

Get the list of items in Venn diagram

<p>It is easy to the draw a Venn diagram with the following code:</p>
<pre><code>library(VennDiagram)

How to fix 'SQLRecoverableException: Closed Connection' in Java
|
<p>We are working for an ecommerce built with Hybris framework and currently we have an issue with database connection (I suppose) and no idea on how to solve it. It happens only on production environment and only on servers that are used by ESB (2 servers in a total of 40).</p>
<p>Basically, sometimes (1-3/day), we discover sessions waiting for some idle session (SEL*NET message from client). We can only manually kill the holder in order to free these sessions.</p>
<p>All the servers share the same application code and the main difference between ESB and Frontend servers is in the controllers that are called and in the requests count.</p>
<p>ESB Server: 10 requests per minute
Frontend Server: 300 requests per minute</p>
<p>In the application log I found a lot of Closed Connection errors on these 2 servers and I think that this is related to our problem but actually I don't know why.
In access.log I have this request:</p>
<pre><code>[26/Mar/2019:09:04:39 +0100] "GET /blockorder?orderCode=XXXX&access_token=XXXX HTTP/1.1" 400 122 "-" "AHC/1.0"
</code></pre>
<p>and in the console.log I have this:</p>

<pre><code> @Override
public boolean requestForcedOrderCancellation(final OrderModel order) {
Transaction.current().begin();
try {
modelService.lock(order.getPk());
modelService.refresh(order);
order.setForcedCancelled(true);
modelService.save(order);
Transaction.current().commit();
return true;
catch (Exception e) {
LOG.error(e.getMessage(), e);
Transaction.current().rollback();
return false;
}
}
</code></pre>
<p>We tried also without explicit locking and the problem is exactly the same.
It seems like the connection is already closed and we cannot rollback (or commit) the transactions that are still waiting in DB.</p>
<p>I expect to avoid this lock and these closed connection errors.</p>

JTable row color depending on Value in model?
|
<p>I have this code in my Table model:</p>
<pre><code>public class DocumentProjectTableModel extends AbstractTableModel{
private List<MyDocument> myDocuments;
public String getValueAt(int row, int column) {
String toReturn = null;
MyDocument myDocument = myDocuments.get(row);
SimpleDateFormat format = new SimpleDateFormat("dd.MM.yyyy");
switch (column) {
case 0:
if(myDocument.getProject().getRegDate()!=null) toReturn = format.format(myDocument.getProject().getRegDate());
break;
case 1:
toReturn = myDocument.getProject().getRegNum();
break;
case 2:
toReturn = myDocument.getProject().getDescription();
break;
case 3:
toReturn = myDocument.getProject().getShortName();
break;
case 4:
toReturn = myDocument.getProject().getSecondName()+myDocument.getProject().getFirstName()+myDocument.getProject().getMiddleName();
break;
}
return toReturn;
}
// some other stuff is not shown
</code></pre>
<p>I want to change background color of each row, for example if <code>myDocument.getIsRegistered() == true</code>, I want this row to have yellow background, if <code>myDocument.getIsValid == false</code> row is blue and so on.</p>
<p>I've found examples that recolor rows depending on values in JTable. But getIsValid and getIsRegistered() aren't actually displayed, they exist only in model. Any advice or example would really help. thanks in advance.</p>
<p>update. my TableCellRenderer:</p>
<pre><code>public class MyTableCellRenderer extends JLabel implements TableCellRenderer {
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int rowIndex, int vColIndex) {
String actualValue = (String) value;
// Set the colors as per the value in the cell...
if(actualValue.equals("lifesucks") ){
setBackground(Color.YELLOW);
}
return this;
}
}
</code></pre>
<p>using renderer:</p>
<pre><code> int vColIndex = 0;
TableColumn col = resultTable.getColumnModel().getColumn(vColIndex);
col.setCellRenderer(new MyTableCellRenderer());
resultTable.setModel(new DocumentProjectTableModel(docs));
</code></pre>
<p>table is shown as usual no yellow color. why?</p>
<p>update2.</p>
<pre><code>resultTable=new JTable(new DocumentProjectTableModel(docs)){
public Component prepareRenderer(TableCellRenderer renderer, int row, int column)
{
Component c = super.prepareRenderer(renderer, row, column);
// Color row based on a cell value
if (!isRowSelected(row)) {
c.setBackground(getBackground());
int modelRow = convertRowIndexToModel(row);
String type = (String) getModel().getValueAt(modelRow, 0);
c.setBackground(Color.GREEN);
}
return c;

How to send POST request to Phil Sturgeon's CodeIgniter RestServer
|
<p>I'm new to CodeIgniter. I'm using Phil Sturgeon's RestServer and RestClient. I've been trying to make a POST request in my CodeIgniter RestClient controller to update data in my CodeIgniter RestServer, but it never updates data in my database. I think my POST request is not right.</p>
<p>Here is my RestClient POST request in controller:</p>
<pre><code>$result = $this->rest->post('newscontroller/news/format/json',
array('news_id' => $news_id,
'news_title' => $news_title,
'news_category' => $news_category ),
'json');
if(isset($result->status) && $result->status == 'success')
{
$data['message'] ='News has been updated.';
$this->load->view('otherpageview',$data);
}
else
{
$data['message'] ='Something has gone wrong';
$this->load->view('otherpageview',$data);
}
</code></pre>
<p>It seems that <strong>$result</strong> doesn't get any value, because I did echo the <strong>$result->status</strong> and it has nothing to display. And I've also have this in this controller's constructor :</p>
<pre><code>// Load the rest client spark
$this->load->spark('restclient/2.1.0');
// Load the library
$this->load->library('rest');
// Run some setup
$this->rest->initialize(array('server' => 'http://api.therestserver.com/index.php/'));
</code></pre>
<p>And in the RestServer's controller, which is <strong>newscontroller</strong>, has this method :</p>
<pre><code>function news_post()
{
$news=array(
'news_id' => $this->post('news_id'),
'news_title' => $this->post('news_title'),
'news_category' => $this->post('news_category') );
$result = $this->News_model->UpdateNews($news);
if($result === FALSE)
{
$this->response(array('status' => 'failed'));
}
else
{
$this->response(array('status' => 'success'));
}
}
</code></pre>
<p>With the <strong>News_model</strong> :</p>
<pre><code>public function UpdateNews($news)
{
$this->db->where('news_id',$news->news_id);
$this->db->update('news',$news);
}
</code></pre>
<p>I just don't know where I'm doing wrong, because I still don't understand how the POST request and method work. I've read through the tutorial in Nettuts and search about this, but still.. maybe because of my bad English reading-writing. I hope someone can help me out, any help would be appreciated. Thanks a TON! :)</p>

How do you REALLY remove Copy from UIMenuController
|
<p>There apparently used to be an <a href="https://stackoverflow.com/questions/4311009/uimenucontroller-in-uiwebview-with-custom-menu-items-without-more-menu/4413464#4413464">easy way</a> to prevent the "More..." label from appearing in UIMenuController when you added more than one custom menu item. You just had to remove all of the system menu items. There was even a <a href="https://stackoverflow.com/questions/3255070/problems-adding-more-than-one-uimenuitem-to-uimenucontroller">workaround here</a> for still having copy work. You just had to implement a custom copy command using a different selector and then override canPerformAction:withSender: to not show the system copy:</p>
<pre><code>-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == @selector(copy:))
return NO;
else
// logic to show or hide other things
}
</code></pre>
<p>Unfortunately this method no longer works (at least in a UIWebView subclass). canPerformAction:withSender: is called for every system menu item except copy: so the result is that the system copy menu item is always displayed. This means that if you have more than one custom menu item, they are always hidden behind "More..."</p>
<p>So, is there a way to really remove the system's copy item or some alternate way to prevent menu items from hiding behind "More..."?</p>
<p><strong>Update</strong></p>
<p>This is the output I get when I override canPerformAction:withSender: notice that the method is never called for the "copy:" action:</p>
<pre><code>cannot perform action cut: with sender <UIMenuController: 0x7227d30>.

</code></pre>
<p>Here I have used below code:</p>
<pre><code>String[] stockArrVideo = new String[Appscontent.Sub_arraylistvideo.size()];
stockArrVideo = Appscontent.Sub_arraylistvideo.toArray(stockArrVideo);
for (String s : stockArrVideo) {
if (s.startsWith(number)) {
String _Substring;
_Substring = s.substring(1);
if(_Substring.equals("")||_Substring == null) {
_Substring = "No Records";
}
Appscontent.Sub_arraylistvideosub.add(_Substring);
}
h++;
}
</code></pre>
<p>If the data is empty, it means I have to display the "No Records" message. Otherwise display the correct data.</p>
<pre><code>TextView mVideo = new TextView(this);
System.out.println(Appscontent.Sub_arraylistvideosub.get(j));
mVideo.setText(Appscontent.Sub_arraylistvideosub.get(j));
mVideo.setLayoutParams(textLayoutParams);
mVideo.setBackgroundColor(Color.BLACK);
</code></pre>
<p>Here I have wrote the code for checking the empty data.</p>
<p>What is causing this exception?</p>
