jQuery SELECT change trigger
|
<p>I use the following jQuery function to perform a slideDown on a DIV, based on the value of a SELECT dropdown:</p>
<pre><code>$(function()
{
$('#show-options').change(function(){
if($(this).val() != '')
{
$('#' + $(this).val()).slideDown();
}
});
});
</code></pre>
<p>HTML:</p>
<pre><code><select id="show-options">
<option value="">Select an Option</option>
<option value="vehicle-type">Vehicle Type</option>
<option value="vehicle-colour">Vehicle Colour</option>
</select>
<div id="vehicle-type" style="display: none;">
<!--form elements in here-->
</div>
<div id="vehicle-colour" style="display: none;">
<!--form elements in here-->
</div>
</code></pre>
<p>Now when the form is submitted, any DIVs that were displayed before submission need to be displayed automatically. I can check for the GET variables in my PHP but I need the jQuery code that will mimic the 'change' function - I think this has something to do with triggers or binds.</p>

How to confirm the insert query is a success?

<p>I am inserting into the database with foll0wing code and it's working fine as I can see the data populates in the db, however I want to capture the result programmatically whether it was a success or failure</p>
<p>1) Here is the code to insert</p>
<pre><code>public void SignUp(String last_name, String first_name, String email,
String password, String confirm_password, String phone) {
Connect connect = new Connect();
Connection conn = connect.Connection();
Statement stmt = conn.createStatement();
String query = "INSERT INTO users VALUES(NULL,('" + last_name + "'),('"

stmt.executeUpdate(query);
conn.close();

ASP.Net Using POST with Server.Execute
|
<p>I'm trying to do something like </p>
<pre><code>Server.Execute("page1.aspx");
</code></pre>
<p>but I need to pass POST data to this page.</p>
<p>Does anyone know how I can achieve this? Since Server.Execute only takes in 3 params, and none of these are anything to do with POST data.</p>
<p><strong>Solution: 7 Hours Later...</strong> </p>
<p>Unfortunately, the only way I was able to do this was to pass the parameters in the query string (using a GET request). I've searched the web for a while now, and finally felt this was good enough for my application. I tested, and somehow the GET URL size limit of 4K chars does not hold good in this context. </p>
<p>I was able to successfully execute a Server.Execute method with 640K+ chars to another page, and it worked beautifully.</p>
<pre><code>Server.Execute("~/pageB.aspx?foo=" + new string('x', 640000));
</code></pre>
<p>In pageB: Page_Load();</p>
<pre><code>Response.Write(Request["foo"].ToString().Length());
</code></pre>
<p>Result: 640000</p>
<p>So I guess this will have to do for now. </p>
<p>I was afraid of having to send large parameters in the query string, but since it works, who am I to complain! :)</p>

Determine if key values in two arrays are equal then update if they are
|
<p>I've taken up PHP programming as a hobby after work and kids. So, my appologies if this code is bogus...but I've been searching for awhile. Anyways, I am trying to compare the values in two arrays and...where each key value equals another I would like to update that value to '1'. So for example, in one array the values are (2, 4, 1) in the second they are (3, 4, 5). Afterwards the the values that would be in my sql column would be updated to (2, 1, 1). Here is my code. Thank you for any help! </p>
<pre><code>$array1 = mysql_fetch_array($x);
$array2 = mysql_fetch_array($x1);
foreach($array1 as $key => $value)
{
if($value == $array2[$key])
{
$v = "UPDATE fXnumber SET xnumber = '1'";
mysql_query($v);
}
}

changing ImageView source
|
<p>I have an ImageView with a source image set in the xml using the following syntax:</p>
<pre><code> <ImageView
android:id="@+id/articleImg"
style="@style/articleImgSmall_2"
android:src="@drawable/default_m" />
</code></pre>
<p>now I need to change this image programmatically. What I need to do is delete the old image and add a new one though. What I have done is this:</p>
<pre><code>myImgView.setBackgroundResource(R.drawable.monkey);
</code></pre>
<p>it works but I noticed android stacks the new image on top of the old one (dont ask me how I found out it's not relevant for the discussion :). I definitely need to get rid of the old one before setting the new image.</p>
<p>how can I achieve that?</p>

php: function breaks when included from different file
|
<p>I'm trying to write a wrapper around Image_Graph bar charts.
I actually wrote the whole thing but in the end didn't work, so now I'm back to the basics.
This code below is taken directly from the ImageGraph website as a bar chart example. I just wrapped it in a function (where $data is ignored for now).</p>
<p>This function works fine if I call it from the same file it's defined in (say, function.php). However, if I make a second file, caller.php where I just include_once or require_once this file function.php and then just call the function, it breaks.</p>
<p>Can anyone help me? I'm probably doing some basic mistake but I just can't figure it out. It might also be something specific to Image_Graph because if I make a simple function that just prints Hello World and call that from another file, it works fine.</p>
<p>Thanks,
Daniel</p>
<pre><code><?php
include_once('Image/Graph.php');
function DrawBarChart($width, $height, $data)
{
// create the graph
$graph = Image_Graph::factory('graph', array($width, $height));
// create the plotarea
$plotArea =& $graph->addNew('plotarea');
// create a dataset
$dataset =& Image_Graph::factory('dataset');
// add points
$dataset->addPoint('Denmark', 10);
$dataset->addPoint('Norway', 3);
$dataset->addPoint('Sweden', 8);
$dataset->addPoint('Finland', 5);
$plot =& $plotArea->addNew('bar', &$dataset);
$graph->done();

jQuery: Select elements that match all of the following classes?
|
<p>I want to select elements that match multiple classes where the classes could be in any order.</p>
<p>I've tried using the <strong>.not()</strong> selector, but it picks all elements that matches <strong>any</strong> of the multiple classes.</p>
<p>What I'm looking for is something so it needs to have <strong>all</strong> of the multiple classes.</p>
<p>Basically <strong>.hasClass()</strong> but for multiple classes and with a return the elements that fits the match.</p>
<p>I've already tried this:</p>
<pre><code>$(".Class1.Class2")
</code></pre>
<p>The problem with that is that is has to be in a certain order which won't work. I need it to work so the classes could be in any order. The element just need to have them, all of them.</p>

Virtual member call in constructor - why is one okay and the other not?

<p>With the code below, Resharper raises a 'virtual member call in constructor' warning:</p>
<pre><code>public class UserDetailViewModel : Screen
{
public UserDetailViewModel()
{
// DisplayName is a virtual member of Screen
DisplayName = "User Details";
}
}
</code></pre>
<p>Whereas if I change the code so it's like this, the warning disappears:</p>
<pre><code>public class UserDetailViewModel : Screen
{
public UserDetailViewModel()
{
SetName();
}
private void SetName()
{
DisplayName = "User Details";
}
}
</code></pre>
<p>Why does one raise a warning and the other not? Is the second way somehow correct, or is it just beyond the limit of what ReSharper can detect as potentially dangerous?</p>

<pre><code>If(image is existing)
- do this
Else
- do others
</code></pre>
<p>Thanks</p>
<p><strong>UPDATE:</strong>

I am trying to write a networking software -firewall in server, proxy?
|
<p>I have question about network programming. My first question was probably about the platform, because the speed and the user friendliness is important. I decided to do it in VC++, not in .net (C#), as I want to use the firewall mechanism, though should find the common way between old windows and after vista, as I was studying about it. Honestly, I have a book titled "Network Programming for Microsoft Windows Second Edition" and another book that is about Active Directory and not an important issue here. I need to use it, too. I don't know how much that book can related to and help my software writing.</p>
<p>My software needs to do the Bandwidth allocation job, it needs to do some packet processing and needs to control the internet usage of all clients in the server that receive internet from server, DHCP maybe or maybe through IP address, I don't know, maybe it is good or needed to write a proxy, as for filtering, too. In fact, I need guidance for writing this software, forgot to say that proxy brings a question about connectionless UDP in my mind, if that's the same way I thought: through sockets make a simple bridge.</p>
<p>Thanks!</p>

<p>The questions:</p>
<p>(a) A final method cannot be overloaded. </p>
<p>(b) A final class cannot be subclassed. (c) A static field is not inherited.</p>
<p>(d) A protected field is only accessible to subclasses.</p>
<p>(e) Every Java class has a unique name.</p>
<p>(f) The import statement is just like C and C++’ s #include statement. </p>
<p>(g) Java always initializes class fields.</p>
<p>(h) Methods in interfaces are always public</p>
<p>(i) abstract classes cannot implement interfaces.</p>
<p>(j) An inner class is a static nested class.</p>

Python Dynamic Class Object Names
|
<p>Just a quick question. I've tried Googling this but every time you add "class" to a Python search it gives you classes on Python. D:</p>
<p>I've found threads like this: <a href="http://stackoverflow.com/questions/5036700/how-can-you-dynamically-create-variables-in-python-via-to-a-while-loop">How can you dynamically create variables in Python via to a while loop?</a></p>
<p>But I don't think that's exactly what I'm looking for since concatenation is also part of the variable.</p>
<p>Here's my while loop:</p>
<pre><code>def main():
counter = 1
while counter <= 3:
print "Name: ",employee[counter].name
print "ID Number: ",employee[counter].id_number
print "Department: ",employee[counter].department
print "Job Title: ",employee[counter].job_title
print #LB
counter = counter + 1
main()
</code></pre>
<p>I have my objects set up as:</p>
<pre><code>employee1 = Employee("Susan Meyers", 47899, "Accounting", "Vice President")
employee2 = Employee("Mark Jones", 39119, "IT", "Programmer")
employee3 = Employee("Joy Rogers", 81774, "Manufacturing", "Engineer")
</code></pre>
<p>This is the error I receive:</p>
<pre><code>print "Name: ",employee[counter].name
NameError: global name 'employee' is not defined
</code></pre>
<p>Obviously I have a class set up as well, but I don't think I need to paste that for this. What I want it to do is go through the loop and change the counter from 1 to 2 to 3. That way it'll loop through all three employees. </p>
<p>Is it possible to do that? I've only ever done this with arrays so I'm not 100% sure I'm on the right track.</p>
<p>Any tips would be great. <3</p>

What's the use of specifying the type of a HashSet when working with the generic Set interface?
|
<p>If you instantiate a new HashSet, you usually use the Set interface to work with it afterwards. Just like</p>
<pre><code>Set<T> set = new HashSet();
</code></pre>
<p>So what is the use of specifying the type of the HashSet explicitly, too? For example:</p>
<pre><code>Set<T> set = new HashSet<T>();
</code></pre>
<p>I've seen it in quite a couple of books, but I can't think of any use at all. If you need access to the set, you'll work with the interface (which is already parameterized) anyway.</p>

Identifying which files to edit when using php based CMS
|
<p>I'm trying to make some edits to a website. The website is based on a CMS and runs on PHP.</p>
<p>I have some html/css experience and have a thick guide to PHP into book to help me. </p>
<p>Among the many edits I'd like to make to the site which are out of the control from the CMS admin area, I'd like to add a Facebook link in the main nav.</p>
<p>Now, I would normally, if inheriting someone else's simpe HTMl/CSS site just use the inspect element feature in Chrome of FF and then see whereabout to edit the code.</p>
<p>Probably a classic rookie question but how does one do that with PHP? If I right click the nav on my site, how do I know which PHP file to edit? Is there a "best way" here?</p>
<p>Here's the site incidentally if it helps at all. I'd like to add (among many other things) a Facebook icon next to the RSS icon in the main nav. I just don't know which file to edit.</p>

Show Add button after Edit button is clicked?
|
<p>I have a view with navigation bar control on the top. The view is in the second level with a "back" button is displayed on the left by default. In my view class, I added a default navigation edit button on the right:</p>
<pre><code>self.navigationbarItem.rightButtonItem = self.editButtonItem;
</code></pre>
<p>with this line of code, an edit button is on the right side, and when it is clicked, the view (table view) becomes editable with delete mark on the left for each row. After that, the edit button's caption becomes "done". All those are done by the default edit button built in the navigation control, I think.</p>
<p>I would like to add an add button the left, or replace "back" button when edit is clicked. I guess I have to implement some kind of delegate in my view class. This would provide a place to plug in my code to add the add button on the left when edit button is clicked, and to restore "back" button back when the done button is clicked. If so, what's the delegate? Or is there any other way to achieve it?</p>

How to reset cursor to the beginning of the same line in Python

<p>Most of questions related to this topics here in SO is as follows:</p>

</blockquote>
<p><a href="http://stackoverflow.com/questions/3249524">Q1</a> <a href="http://stackoverflow.com/questions/493386">Q2</a>.</p>
<p>Instead, my question is as follows:</p>
<p>I expect to see the following effect,</p>
<pre><code>>> You have finished 10%
</code></pre>
<p>where the <code>10</code> keep increasing in the same time. I know how to do this in C++ but cannot
find a good solution in python.</p>
<p>// ================== Updated ==============================================
Based on the helps from aix and petr, here is the solution to this question:</p>
<pre><code># for Python 3
for i in range(0, 101, 10):
print('\r>> You have finished %d%%' % i, end='\r')
sys.stdout.flush()
time.sleep(1)

create an array from a text file or another array that is based on tabbed spaces?
|
<p>What I am ultimately trying to do is take a text file that looks like below and organize them into something I can use like an array based on tabbed spaces. </p>
<p>// Example //</p>
<pre><code>this is no tabbed space
this is a tabbed space
this is 2 tabbed spaces
this is no tabbed space
</code></pre>
<p>I would like to end up with:(using PHP preferably)</p>
<pre><code>$list= array(no \t("string", "string", "string", one \t ("string", "string", "string",
tw0 \t("string", "string", "string", etc..)),
no \t again starts new("string", "string", array());
</code></pre>
<p>I need to keep nesting based on \t spaces and start over when I hit no \t space.
Any suggestions or better ways to do this?</p>
<p>I need to use this list from a text file to insert into database as categories and use for menu items that have sub levels and as many needed depending on the text file.</p>
<p>I figured out how to get them into one array but is there a way to organize them by the tabbed spaces or maybe by if greater than a certain amount of spaces etc..? I am just confused at this piont been trying many different ways but I am truly lost.</p>

What does "new" use when a runtime library is not used?
|
<p>In C for example, there is no malloc() without a runtime library (libc). And I think for example, on Windows malloc just calls HeapAlloc(). But in C++, the way to allocate dynamic memory is actually a keyword of the language; same for "delete". So therefore, how would "new" work if you compiled your code without a runtime library?</p>
<p>Thanks</p>

How to trigger a button inside a listview (Android)?
|
<p>I have an activity that extends ListActivity, now I want to enable the click listener button in each row of the list. I did read some similar questions like this, but most of that extend from BaseAdapter to get the button. Actually, with the code below the button event was fired, however I have to double click on the row to fire the event.</p>
<pre><code> @Override
// How can I trigger a single button instead of firing whole the row
protected void onListItemClick(ListView l, View v,final int position, long id) {
super.onListItemClick(l, v, position, id);
//removeTask(position);
ImageView remove = (ImageView)v.findViewById(R.id.remove_task);
remove.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
removeTask(position);
}
});
}

Is there a way to tell when a python file is loaded using PYTHONSTARTUP vs. being run as a script?
|
<p>All,
I recently discovered the PYTHONSTARTUP environment variable, and am looking forward to setting up several of my utility functions to automatically load into my interpreter. However, one thing I'd like to be able to do is use the same script to setup the environment variable itself. </p>
<p>My issue is determining when the file is run as a script. My thought was to use the <code>if __name__ == "__main__":</code> trick to determine when the file was run as a script, but testing showed that when the file is loaded via PYTHONSTARTUP the name shows as <code>"__main__"</code>.</p>
<p>Does anyone know of a way to identify when a file is run as a script vs. when it is loaded via PYTHONSTARTUP?</p>

BitmapFactory.decodeByteArray doesn't keep color information when pixel is fully transparent
|
<p>I use the BitmapFactory.decodeByteArray to generate a Bitmap from a PNG image. Then I use Bitmap.getPixels to retrive all the pixel data. The problem is that when a pixel is set as fully transparent, all the color data seams to be discarded. 0x0000ff00 is being returned as 0x00000000. If I create an image from code which has transparent pixels I make a copy, render that to a canvas, use Canvas.drawColor(0xff000000, Mode.DST_ATOP) and then get all the correct color values with getPixels and then add that with the alpha values I got from the first getPixels call. I can't do that now since the color information seams to be gone.
Is there any way to make sure that the color information is stored when generating a Bitmap from a PNG file using the BitmapFactory?</p>

DataKeyNames in databound controls must be a property?

<p>I use a ListView along with an ObjectDataSource tied to a business object. This object is defined as follows:</p>
<pre><code>public class Employee

public int Id;
public string Name;

<p>When I try setting the DataKeyNames property of the ListView to Id, ASP.net blows up and says:</p>
<p><strong>DataBinding: 'Employee' does not contain a property with the name 'Id'.</strong></p>
<p>However, when I change the object to that:</p>
<pre><code>public class Employee
{
public int Id {get; set;}
public string Name;
}
</code></pre>
<p>It works!!!</p>
<p>I couldn't find any documentation about this behavior. Why is it not accepting a simple variable for DataKeyNames and instead it insists on a property?</p>

Overriding ctrl-= in javascript
|
<p>I'm building a basic online graphics editor, and I want to override the browser zoom, when the user hits Ctrl-= (that is the ctrl key followed by the = key) I want the canvas to get larger (I'll handle this via an event), but any attempt to capture this key combination causes my event to fire and then the page to resize anyway. How do I avoid the browser continuing to resize my browser?</p>
<p>I tried this with other keycodes, ctrl-s does not fire the browser save if I override it for example.</p>
<p>I realise this isn't an amazing usability idea generally, but in the given context of a design application I believe it to be ok.</p>

'Google Docs like ' functionality in python

<p>What I have is a UI which allows users to enter info about, say toys.<br>
Now the UI is accessible to multiple users at the same time and the info stored by the user gets stored in a file, which may cause accidental overwriting of toy info.<br>
The file will contain info of multiple toys but same toy info can not show up again which is quite possible in multi user environment.<br>
I am fairly new to web dev. and python too.<br>
What should be my first steps to resolve this problem?<br></p>

Counting values in an array w/ PHP

<p>I need to perform a a task when there are some values in my array. So I used <strong>count</strong></p>
<pre><code>count($_SESSION['arrayValues'][$_SESSION['event']]);

<p>And my code acts as if there's something in the array, however when I do print_r I get the following:</p>

Using Helper Classes in PowerMock
|
<p>I am unit testing some code using PowerMock and Mockito. </p>
<p>There are several types of patterns that come up during unit testing of all classes in the project I am working on.</p>
<p>What I would like to do is create a shared Helper class to avoid code duplication. The issue is that when I move the code to the Helper and attempt to call it from my test class, PowerMock's functionality doesn't carry to the Helper and I simply get Mockito errors (cannot mock final classes).</p>
<p>I tried putting the @PrepareForTest attribute at the head of the Helper class and methods but with no luck. Is there any way to make this work (aside from inheriting from the Helper)?</p>

Is it possible to get variable name of a reference type
|
<p>Is it possible to get the name of a variable that points to a reference? Take the example below:</p>
<pre><code>private void FillArray(int[] array, int count)
{
array = new int[count];
for (int i = 0; i < array.Length; i++)
{
array[i] = i;
}
Debug.WriteLine("Array {0} is now filled up with {1} values", array.Name, count);
}
</code></pre>
<p>There is no property <code>Name</code> for the array that is going to be used in the above method. I know that a workaround would be adding another parameter as string and assign the name to it, but how to do this programitically? Also I know I can make my own implementation, but I am interested to know the answer to this particular question!</p>

Wait for two events with jQuery and execute a callback when both are done
|
<p>So I have a .click() event on an element. After it's closed, this mob has a transition that happens and an AJAX call that goes through. That's all that happens.</p>
<p>What I need is a callback to put inside the <code>.click()</code> function to execute when both of those things are done, even if transitions aren't supported. Here's a timeline:</p>
<p>jQueyr needs to wait for the ajax call and the transition, then execute the callback after the ajax call has completed AND the transition has either finished or not happened at all.</p>
<p>How can I do this? Thanks!</p>
<p><em>NOTE: I'm using <code>$.ajax()</code> for the ajax call and a normal CSS3 transition on the element in question. I can detect transitionEnd with javascript event binding, I have a variable setup for that called transitionEnd and another variable that detects if the browser support transitions call supportsTrans.</em></p>

How do I make a python script wait for sometime?
|
<p>I'm relatively new to python and I have written a single python script which does the following:</p>
<ol>
<li>It does some operation and writes the details to a text file(say a.txt)<br/></li>
<li>Once the txt file(a.file) is written, the same file is read to do some operations.</li>
</ol>
<p>The problem I face is once the file(a.txt) is written and same is read, the contents are not read.</p>
<p>I use <code>time.sleep()</code> after the txt file(a.txt) is written and then proceeded with reading the same.</p>
<p>But whats happening is the script is stopping it's execution for the time period mentioned in the sleep method and the txt file is not read.</p>
<p>I need a scenario where the same script must write to a text file and read instantly.</p>
<p>Could someone help me please? Thanks in advance.</p>

How to delete multiple entries from a List without going out of range?

<p>I have a list of integers that contains a number of values (say, 200).</p>
<pre><code>List<int> ExampleList;
</code></pre>
<p>And another list on integers that holds the indexes that need to be deleted from ExampleList. However, this list is not sorted.</p>
<pre><code>List<int> RemoveFromExampleList;
</code></pre>
<p>If it were sorted, I would have run a reverse loop and deleted all the values like this:</p>
<pre><code>for (int i = (RemoveFromExampleList.Count-1); i >=0; i--)
{
ExampleList.RemoveAt(RemoveFromExampleList[i]);
}
</code></pre>
<p>Do I have to sort RemoveFromExampleList, or is there another way to prune the unnecessary values from ExampleList?</p>
<p>If I do have to sort, whats the easiest way to sort? Is there any inbuilt C# library/method to sort? </p>

Module API mismatch between PHP and SSH2 module

Downloading an XML file as string in C# keeps getting me gibberish

The weird thing is that when I open those files with my browser (Firefox) I get the data as I should, and not the gibberish.</p>
<p>This is my code to download the data:</p>
<pre><code>public static string Read(string Address)
{
return new WebClient().DownloadString(Address);
}
</code></pre>
<p>And this is an example of a file I get gibberish when downloading: <a href="http://thetvdb.com/api/C40F55BF6975A295/series/80379/default/5/16/en.xml" rel="nofollow">http://thetvdb.com/api/C40F55BF6975A295/series/80379/default/5/16/en.xml</a></p>
