position of UITabbar
|
<p>I try to place UITabbar on iPhone window using CGRectMake.
But I found that the Y position is different from the display in Interface Builder.</p>
<p>Is there anyone met the same problem?</p>
<p>Using CGRectMake to locate the x,y position, is it possible cause the refusing from App stoe due to compatible reason?</p>
<p>Thanks</p>

The equals() method in Java works unexpectedly on Long data type
|
<p>Let's first consider the following expressions in Java.</p>
<pre><code>Integer temp = new Integer(1);
System.out.println(temp.equals(1));
if(temp.equals(1))
{
System.out.println("The if block executed.");
}
</code></pre>
<p>These all statements work just fine. There is no question about it. The expression <code>temp.equals(1)</code> is evaluated to <code>true</code> as expected and the only statement within the <code>if</code> block is executed consequently.</p>
<hr>
<p>Now, when I change the data type from <code>Integer</code> to <code>Long</code>, the statement <code>temp1.equals(1)</code> is unexpectedly evaluated to <code>false</code> as follows.</p>
<pre><code>Long temp1 = new Long(1);
System.out.println(temp1.equals(1));
if(temp1.equals(1))
{
System.out.println("The if block executed.");
}
</code></pre>
<p>These are the equivalent statements to those mentioned in the preceding snippet just the data type has been changed and they behave exactly opposite. </p>
<p>The expression <code>temp1.equals(1)</code> is evaluated to <code>false</code> and consequently, the only statement within the <code>if</code> block is not executed which the reverse of the preceding statements. How?</p>

Passing intent to another android app
|
<p>I know that another application accepts intent type: vnd.android.cursor.item/postal-address</p>
<p>I can make it show by calling:</p>
<pre><code>Uri dataUri = Uri.parse("test");
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(dataUri, "vnd.android.cursor.item/postal-address");
</code></pre>
<p>Question is, how to pass well formated address?</p>
<p>E.g. i I pass
Uri dataUri = Uri.parse("content://com.android.contacts/data/2057");
it works, but I want to pass new address (not from Contacts).</p>
<p><strong>UPDATE</strong>: This external application has two intent-filters:</p>
<p>intent-filter:
action: 'android.intent.action.MAIN'
category: 'android.intent.category.DEFAULT'
data:
mimeType: 'vnd.android.cursor.item/postal-address'</p>
<p>intent-filter:
action: 'android.intent.action.MAIN'
category: 'android.intent.category.DEFAULT'
data:
mimeType: 'vnd.android.cursor.item/postal-address_V2'
scheme: 'content'
host: 'com.android.contacts'</p>
<p>Thank you.</p>

Need a scenario where would fail Array.ConstrainedCopy()
|
<p>Just playing around with some of the APIs in .NET and I can't seem to find a way to cause Array.ConstrainedCopy() fail.</p>
<p>According to MSDN, it's treated as an atomic operation. If it fails during the copy, the entire call fails resulting in no elements being copied as opposed to its Array.Copy() counterpart.</p>
<p>Can someone demonstrate this or tell me how to do this?</p>
<p>This code fails in both types of copy. I'd like to see an example of Array.Copy() only copying some elements to get a better understanding of where I might use either forms of copy.</p>
<pre><code>object[] yer = new object[] { "as", "qwe", "re", 1 };
string[] copy = new string[yer.Length];
Array.ConstrainedCopy(yer, 0, copy, 0, yer.Length); // runtime error
Array.Copy(yer, 0, copy, 0, yer.Length); //runtime error

{
sw.WriteLine(lockedFilePath);

{
using (System.IO.StreamWriter sw = new StreamWriter(fs))
{
sw.WriteLine(lockedFilePath);
}
}
}
}
</code></pre>
<p>but If I call it in a Console App like this </p>
<pre><code>foreach (string f in System.IO.Directory.GetFiles(@"C:\AASource"))
{
Console.WriteLine("Logging : " + f);
LogFile(f);
}
Console.ReadLine();
</code></pre>
<p>The only file that is listed in the resulting text file is the last file in the dir.

Jquery remove table element
|
<p>I have some jquery code that removes a table row. The problem is when I remove it, it forces my page to goto the top.
The table row has a remove link that removes itself. I am assuming this is the issue that makes it scroll back to the top. I have tried setting the focus of another element outside to be focused after the removal but no joy.
I have now used the offset and scrolled to it, but it looks awful.
Anybody know how to stop the repositioning.</p>
<p>Thanks</p>

FInvoke(function () { echo "Direct Invoke Worked\n"; });

<p>However, If I slightly modify it to add another level of indirection, it fails:</p>
<pre><code>function FInvoke($func) {
$func();
}
function FIndirectInvoke($func) {
FInvoke(function () {
$func();
});
}
FIndirectInvoke(function () { echo "Never makes it here"; });

Will setting a file's modification time to the future with touch() work accross the board?
|
<p>I have a caching class that has a flat file driver, meaning you can cache arbitrary data to a flat file using a key and expiration time, then retrieve this data using the same key.</p>
<p>Expire duration must be set with the setCache method in order to work with other drivers (as opposed to having an expiration duration argument on the getCache method, even though this would make determining whether the cache has expired much easier, as I could just compare it to the files last modification time).</p>
<p>Currently I prepend a timestamp (+ expire duration) to the beginning of the file. When a user tries to getCache related to that file, the method opens the file and strips off the first line to get this timestamp. It then uses that timestamp to figure out whether or not that cache has expired. This is not very efficient obviously.</p>
<p>I recently came accross a PHP function touch(), which allows me to set a file's last modification time to an arbitrary value. This sounds awesome because it would allow me to (instead of the above mentioned method of figuring out if the cache has expired), set the file's last modification time to some point in the future. I can then check this time to see if the cache has expired yet.</p>
<p>I really REALLY want to be able to use this. My application is distributed however, and since this function works with the environment, I am not sure if I should trust this function to work as expected accross the board on different systems. Does anyone have any information or resources about the compatability of this function?</p>

How can I overlay traffic data on googlemaps
|
<p>I am using Google maps API for android application development. I have traffic data for a certain city in my database, which should be displayed on Google map with different colors. How can I overlay that data on Google maps for specified city/county?
Do I need to use KML or such kind of stuff for coordinates of city/county?
Thanks,

jQuery - How do I test what type of selector is passing the value?
|
<p>I am using the latest and greatest jQuery. I am trying to make my code efficient and reusable throughout a specific site and want consolidate a block.</p>
<p>I have a piece of code that listens for a save button being clicked. When the save button is clicked, it figures out which selector was click and gets its id and value.</p>
<p>This code works perfectly for text boxes. I just want to be able to run select boxes, radio buttons, and check boxes through it too. I need to handle the data differently depending on whether it's a checkbox, radio, or text field.</p>
<p>If I know the id of a selector, how can I easily test which type of selector it is?</p>
<p>In pseudocode:</p>
<pre><code>if (SelectorType == 'radio') {
// do radio stuff
} else if (SelectorType == 'text') {
// do test field stuff
} else if (SelectorType == 'checkbox') {
// do checkbox stuff
}
</code></pre>
<p>ANSWER</p>
<p>This is what I was trying to get at: </p>
<pre><code> var ThisField = $(this).parent().parent().children("td:eq(1)").children(":input").attr("id");
var FieldType = $("#"+ThisField).prop("type");
if (FieldType == "select-one") {
alert("You are trying to save select box info!");
} else if (FieldType == "text") {
alert("You are trying to save text info!");
} else if (FieldType == "checkbox") {
alert("You are trying to save checkbox info!");
} else if (FieldType == "radio") {
alert("You are trying to save radio info!");
}

<p>How would i go aobut setting it up so ## is the value of MyName3D. Again I haven't done anything like this before. Just wanted to give it a try?</p>
<p>Would be really appreciated if I could get some detail onto how it works.</p>

Problem with memory usage measurment
|
<p>I have some C# functions, and I want to measure their memory usage in bytes. I used GC.GetTotalMemory as follows:</p>
<pre><code>long val1 = GC.GetTotalMemory(false);
// my code
long val2 = GC.GetTotalMemory(false);
long result = val2 - val1 ;
</code></pre>
<p>I tried to pass both true and false as argument for GC.GetTotalMemory, but I do not know why I get negative result value, when I subtract val1 from val2 .... Another issue is that GC.GetTotalMemory give different values in each excution, I think it is not accurate </p>
<p>Can anyone know why I get a negative result value ? is it because of the argumenet (true or false), although I tried them both and got negative result value too</p>
<p>Can anyone know why I get different values in each excution of the C# function ?</p>
<p>Please if anyone has a better efficient way to measure memory usage in bytes for C# function in Windows, please tell me and thanks alot </p>

Call a C++ function from a C++ library in Linux

<p>I want to call a function from C++ library on linux. I have a shared object of that library.
I want to call method getAge() that return an int from ydmg library.</p>
<p>Following is the code that I have written:</p>
<p>testydmg.cpp</p>
<pre><code>#include "ydmg/bd.h"
#include "yut/hash.h"
#include "dlfcn.h"
extern "C" int getAge();
class testydmg{
public:
testydmg::testydmg(const yutHash& user){
}
testydmg::testydmg(){
}
testydmg::~testydmg(){
}
int testydmg::getFunction(){
void *handle;
int (*voidfnc)();
handle = dlopen("ydmg.so",RTLD_LAZY);
if(handle == NULL){
printf("error in opening ydmg lib");
} else {
voidfnc = (int (*)())dlsym(handle, "getAge");
(*voidfnc)();
printf("class loaded");
}
ydmgBd obj;
obj.getAge();
printf("Inside getFunction()...");
dlclose(handle);
}
};
</code></pre>
<p>I compile and link the code as below:</p>
<blockquote>
<p>gcc -fPIC -shared -l stdc++ -I/home/y/libexec64/jdk1.6.0/include -I/home/y/libexec64/jdk1.6.0/include/linux -I/home/y/include testydmg.cpp -o libTestYdmg.so libydmg.so</p>
</blockquote>
<p>Then I check for the method in the new shared object i.e. libTestYdmg.so</p>
<blockquote>
<p>nm -C libTestYdmg.so | egrep getAge
I get nothing by running the above command.</p>
</blockquote>
<p>Does it mean that it did not get the method getAge() from the library.
Could you please correct where I am going wrong ?</p>

absolute path source php

<p>This is maybe just a trivial question, but I don't really know what is the best practice to include, says javascript, img, or css using absolute path</p>
<p>What I am really using right now is using the code like this</p>
<pre><code><?php
$prefix = '//';
$rootFolder = $prefix . $_SERVER['HTTP_HOST'];
?>
</code></pre>
<p>so then when i want to include something like jquery, I would just type the code like this</p>
<pre><code><script type="text/javascript" src="<?php echo $rootFolder ?>/jquery-1.7.1.min.js"></script>

<p>is this good enough? Or should I modify the prefix to "http://" or maybe there is some better way using another superglobal variable and such?</p>

Problem in implementing my own switch class

<p>I am trying to implement a custom switch case just for fun..</p>
<p>The approach is that I have created a class that inherits a dictionary object</p>
<pre><code>public class MySwitch<T> : Dictionary<string, Func<T>>
{
public T Execute(string key)
{
if (this.ContainsKey(key)) return this[key]();
else return default(T);
}
}

<pre><code> new MySwitch<int>
{
{ "case 1", ()=> MessageBox.Show("From1") },
{ "case 2..10", ()=>MessageBox.Show("From 2 to 10") },
}.Execute("case 2..10");
</code></pre>
<p>But if I specify <strong>"case 2"</strong> it gives a default value as the key is not in the dictionary.</p>
<p>The whole purpose of making <strong>"case 2..10 "</strong> is that if the user enters anything between <strong>case 2 to case 10</strong>, it will execute the same value.</p>
<p>Could anyone please help me in solving this?</p>

Loop thru a list and stop when the first string is found
|
<p>I have a list and I want to extract to another list the data that exist between top_row and bottom_row.
I know the top_row and also that the bottom_row corresponds to data[0] = last integer data (next row is made of strings, but there are also rows with integers which I'm not interested).</p>
<p>I've tried several things, but w/o success:</p>
<pre><code>for row,data in enumerate(fileData):
if row > row_elements: #top_row
try:
n = int(data[0])
aux = True
except:
n = 0
while aux: #until it finds the bottom_row
elements.append(data)
</code></pre>
<p>The problem is that it never iterates the second row, if I replace while with if I get all rows which the first column is an integer.</p>
<p>fileData is like:</p>
<pre><code>*Element, type=B31H
1, 1, 2
2, 2, 3
.
.
.
359, 374, 375

*Elset, elset=PART-1-1_LEDGER-1-LIN-1-2-RAD-2__PICKEDSET2, generate

Using javascript to check which CDN jQuery is cached from on the client

<p>Can I use JavaScript to check whether JQuery is (already) downloaded (cached) on the target web browser (user) or not? For Example:</p>
<pre><code>If (JQuery-from-Microsoft-CDN-downloaded)
Then use http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.js
Else if (JQuery-from-Google-APIs- downloaded)
Then use http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js
Else if (JQuery-from-code.jquery.com- downloaded)
Then use http://code.jquery.com/jquery-1.4.4.min.js
Else use jQuery from my own website.
</code></pre>
<p>Means that using the ability of javascript to check whether one of them is downloaded on the target User (Web Browser), if not then use jQuery from my own website otherwise if true then use that version of JQuery that is downloaded on the target User.</p>

Spatial Vector, Color Vector
|
<p>Say you have two things (spatial vector, color vector) that are conceptually different (pos in space vs color) yet they actually end up needing the same types of operations - overloaded plus, minus, scalar multiply.</p>
<p>A nice solution in the Cg programming language was they actually aliased member names .xyzw and .rgba. So in Cg you can do</p>
<pre><code>float4 vector = float4( 4, 3, 2, 1 );
float red = vector.r ;
float x = vector.x ;
// both red and x will have the value 4.0.
</code></pre>
<p>So the question is: How do you deal with things that are conceptually different but programmatically the same? I could simply use a class Vector and "remember" that .x = .r, .y = .g and so on, which isn't that hard but appears somehow misleading.</p>
<p>The other option is to totally repeat the code in Vector and Color.</p>
<p>Which is better? <em>Repeating code</em> for readability's sake, or <em>just living with the bad naming</em>?</p>

Unable to build Eclipse library projects after ADT update
|
<p>I have a main project (mainapp) I am developing for Android under Eclipse. It uses the facebook-android-sdk library (fblib) which is a separate Eclipse project with it's project properties checked as "Library". Under the project properties > android section for mainapp, I have fblib added as a library. everything works fine. </p>
<p>I needed to create a new version of mainapp which uses different database files (assets subdirectory). To do this, I created a new Eclipse project (newapp) and setup mainapp as a library under project properties > android. </p>
<p>Everything was working fine until the latest ADT update. I am getting errors trying to build/run newapp (Conversion to Dalvik format failed with error 1). If I go to mainapp and uncheck "Library" from project properties > android, I can build mainapp as a regular application and it seems to work just fine.</p>
<p>I've searched for multiple jar files in project directories, updated proguard to 4.8beta, deleted/added jars to the build path, removed exports, added exports, deleted dependencies, added "lib" directories, cleaned, restarted, rebooted and pretty much anything else google would turn up, but to no avail. </p>
<p>It was all working fine with ADT 16 so I'm really confused here. Has adding a library project to an application, which also incorporates a library project, become somehow deprecated? I just can't seem to get this working.</p>

Assignment to None
|
<p>I have a function which returns 3 numbers, e.g.:</p>
<pre><code>def numbers():
return 1,2,3
</code></pre>
<p>usually I call this function to receive all three returned numbers e.g.:</p>
<pre><code>a, b, c = numbers()
</code></pre>
<p>However, I have one case in which I only need the first returned number.
I tried using:</p>
<pre><code>a, None, None = numbers()
</code></pre>
<p>But I receive "SyntaxError: assignment to None".</p>
<p>I know, of course, that I can use the first option I mentioned and then simply not use the "b" and "c" variables. However, this seems like a "waste" of two vars and feels like wrong programming.</p>

How to create a Very VERY Simple proxy to a specific page/feed
|
<p>I have a simple problem. Living in Ch*na we don't have access to much of the social media sites. So I want to create a php file that fetches the content of a blocked rss file and output's itself as that rss.</p>
<p>unblockedserver.com/twittfeed.php?id=23038034</p>
<pre><code><?php
$id = (int)$_GET['id'];
$url='http://twitter.com/statuses/user_timeline/'.$id .'.rss';
header("Content-Type: application/xml; charset=ISO-8859-1");
$feed = getthecontentfromthe($url);? // what goes here?
echo $feed;
</code></pre>
<p>The main site handles the caching and generally the url/page will be a secret, so i hope this will be simple enough.<br>

jQuery: show() keeps adding display:block
|
<p>I'm having a little issue right now that has turned into a festering wound.</p>
<p>I've recreated Google Business Hours for setting which hours during the week that a company is open, or whether they are closed on that day. Now, if they are closed, the user can select a checkbox and the times DIV hides. Right now I'm using .show() and .hide()</p>
<p>Now, let's say that a user closes the fist day and decides to "apply all" to the rest of the days of the week... I loop through and close the remaining 6 days. However, if a user has modified a day in the middle of the week, the .show() or .hide() functions automatically add "display: block" ... this messes up the loop.</p>
<p>Why is jQuery adding this styling when it was never there originally, and is there a clean way of removing it within a loop before I apply the .show() or .hide()?</p>

HttpRequestValidationException when signing out
|
<p>On my master page I have a LoginStatus control which allows users to sign out of the application. The problem is that if within the page, the user enters invalid data like "<test>" and then, <em>without</em> submitting the form, the user clicks "sign out" a HttpRequestValidationException is raised. When the user clicks "sign out", any pending input is going to be discarded anyway.</p>
<p>What I ended up doing is using javascript to call reset() on the form when the user clicks "sign out." This circumvents the HttpRequestValidationException problem adequately. Does anyone have other suggestions for how to deal with this scenario?</p>

<p>UPDATED Question. I'm trying to achieve the following revision of the answer:</p>
<pre><code>$('.listitem_to_hover').hover(function () {
var senderID = sender.id.replace('listitem-', '');
$('#anotheritem-' + senderID).show();
}, function () {
var senderID = sender.id.replace('listitem-', '');
$('#anotheritem-' + senderID).hide();
});
</code></pre>

JQuery Change Class With Animate
|
<p>I am making a side menu that pops out when you click the tab. I have come to the point where I do not know how to continue on, I need the class on the tab div to change to "sideopen" when it is clicked. I have tried <code>attr();</code> and I also tried <code>removeClass();</code> and <code>addClass();</code> but to no avail.</p>
<p>Here is the code on JSFiddle: <a href="http://jsfiddle.net/bGKvR/" rel="nofollow">http://jsfiddle.net/bGKvR/</a></p>
<p>Also, I am a newbie to JS/JQuery so any advice to cleaning the code up is extremely appreciated.</p>

Why does List<T> implement IList<T>, ICollection<T> and IEnumerable<T>?
|
<p>If you go to definition of <code>List<T></code> you would see the following:</p>
<pre><code>public class List<T> : IList<T>, ICollection<T>, IEnumerable<T>
</code></pre>
<p><code>IList<T></code> already inherits from both <code>ICollection<T></code> and <code>IEnumerable<T></code>.</p>
<p>Wouldn't it have been sufficient if <code>List<T></code> only implemented <code>IList<T></code>?</p>

FileSystemWatcher, unsubscribe from the event
|
<p>I'm fooling around with the FileSystemWatcher in 4.0. I find this very useful but am getting caught in a loop. I'm trying to monitor whenever an ini is changed and change it back to the correct default (long story) however the change event copying over the new file is causing it to drop into a loop ... Any Ideas > ? I played around with the idea of deleting and recreating thefile to avoid triggering the changed event but this leads to another set of issues with the program that I'd rather avoid. Also I'd imagine I could overwrite the text but this also poses the same issue. Thanks in advance for the help</p>
<pre><code> static void Main() { Watch (@"\\NoFault2010\Lexis\Data\Setup\", "tmconfig.ini", true); }
static void Watch (string path, string filter, bool includeSubDirs)
{
using (var watcher = new FileSystemWatcher (path, filter))
{
watcher.Changed += FileChanged;
watcher.EnableRaisingEvents = true;
Console.WriteLine("Do Not Close ... \n\nThis is a Temporary Configuration Manager for Time Matters ... \n\n\nI'm Listening ............");
Console.ReadLine();
}
}
static void FileChanged (object o, FileSystemEventArgs e)
{
string _right_stuff = @"\\NOFAULT2010\Lexis\Data\Templates\Programs\tmconfig.ini";
string _working = @"\\NOFAULT2010\Lexis\Data\Setup\tmconfig.ini";
System.Threading.Thread.Sleep(2000);
File.Copy(_right_stuff, _working, true);
Console.WriteLine("File {0} has been {1}", e.FullPath, e.ChangeType);
MAIL_IT("SQLMail@lcjlawfirm.com", "TM Master.INI has been altered", "Check the Master INI and Yell At Ecopy Guy " + e.ChangeType + e.FullPath);
}
</code></pre>
<p>How would I unsubscribe from the event to avoid entering into this loop.</p>

How to add alert dialog onKeyDown?
|
<p>I have this code on my application </p>
<pre><code>@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
Intent a = new Intent(this,a_stages.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(a);
return true;
}
return super.onKeyDown(keyCode, event);
}
</code></pre>
<p>now I want to add an alert dialog that will ask the user if he/she wants to go, for example on another page, if the user clicks on yes, it will intent to a specific page and if the user clicks on cancel, dialog.cancel();.</p>
<p><strong>EDIT</strong>
I tried this code but I got an error on the line "Intent a = new Intent(this,a_stages.class);" that says "The constructor Intent(new DialogInterface.OnClickListener(){}, Class) is undefined" </p>
<pre><code>@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(bq1.this);
// Setting Dialog Title
alertDialog.setTitle("Go back to home");
// Setting Dialog Message
alertDialog.setMessage("Are you sure you want to go back to home?");
// Setting Positive "Yes" Button
alertDialog.setPositiveButton("YES", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
Intent a = new Intent(this,a_stages.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(a);
}
});
// Setting Negative "NO" Button
alertDialog.setNegativeButton("NO", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Write your code here to invoke NO event
dialog.cancel();
}
});
// Showing Alert Message
alertDialog.show();
}
return super.onKeyDown(keyCode, event);
}

Java Millis to nanoseconds
|
<p>I have just started to learn Java, and I want to make random array and to measure time. I used <code>System.currentTimeMillis();</code> at the beginning of filling my array, and the same at then and. Then I wanted to convert milliseconds to nanoseconds and used <code>long total=TimeUnit.MILLISECONDS.toNanos(time1);</code> but trouble occurred:</p>
<pre><code>import java.util.*;
import java.util.concurrent.TimeUnit;
public class main {
public static void main(String[] args) {
long time1,time2,time3;
int [] array = new int[10];
Random rand =new Random(100);
time1=System.currentTimeMillis();
for(int i=0;i<array.length;i++){
array[i]=rand.nextInt(100);
}
time2=System.currentTimeMillis()-time1;
long total=TimeUnit.MILLISECONDS.toNanos(time1);
System.out.println("Time is:"+time1
);
}
}
</code></pre>
<p>In the end I got 'Time is:1361703051169;' I think that something's wrong with this.</p>
