Switching a Repeater's ItemTemplate at runtime
|
<p>Is it possible to define multiple templates for a Repeater's ItemTemplate and switch between them according to some condition?</p>
<p>I use a repeater to view a list of posts but want to have a different view for rows that belong to the current user (e.g. contains a LinkButton for deleting the post)</p>
<p>If this is not possible, then is it possible to use a Multiview control inside a Repeater's ItemTemplate?</p>

<p>Which of the following will evaluate to true only if boolean expressions <code>A</code>, <code>B</code>, and <code>C</code> are all <code>false</code>?</p>
<blockquote>
<p><em>Answer:</em> <code>!(A || B || C)</code><br>
<em>My answer:</em> <code>!(A && B && C)</code></p>
</blockquote>
<p>Why is my answer incorrect? If <code>A</code>, <code>B</code> and <code>C</code> are all <code>false</code> and the <code>!</code> is distributed, it will make all of them <code>true</code>, thus returning <code>true</code>.</p>
<hr>
<p>Given that <code>a</code>, <code>b</code> and <code>c</code> are integers, consider the boolean expression</p>
<pre><code>(a < b) || !((c == a * b) && (c < a))
</code></pre>
<p>Which of the following will guarantee that the expression is <code>true</code>?</p>
<blockquote>
<p><em>Answer:</em> <code>c < a</code> is <code>false</code></p>
</blockquote>
<p>Doesn't the result rely on <code>(c == a * b)</code> being <code>false</code> also because of the <code>&&</code>? </p>

Encrypting hypelinkfields in gridview
|
<p>I need to encrypt the Url's in my web application. I followed Mads Kristensen's (http://madskristensen.net/post/HttpModule-for-query-string-encryption.aspx) article for encrypting Urls. It is working perfectly. However, I have hyperlinkfield in a gridview for which I am using datanavigateurlformatstring and datanavigateurlfields properties to create the query string e.g</p>
<pre><code> <asp:HyperLinkField Text="Edit" datanavigateurlfields="DocumentId"
datanavigateurlformatstring="~\admin\edit_document.aspx?DocumentId={0}" />
</code></pre>
<p>When the hyperlinks are clicked, the link opens and the urls are encrypted. However, if I hover my mouse over the hyperlinks, I can see data in the query string with no encryption. Any idea how to encrypt the query string when the mouse is hovered over the hyperlink?.</p>
<p>Thanks.</p>

How come some people append f to the end of variables?
|
<p>In the tutorial I'm reading for OGRE3d <a href="http://www.ogre3d.org/tikiwiki/tiki-index.php?page=Intermediate+Tutorial+1" rel="nofollow">here</a> the programmer is constantly adding <code>f</code> at the end of any variable he initializes, like <code>200.00f</code> or <code>0.00f</code> so I decided to erase <code>f</code> and see if it compiles and it compiles just fine, what is the point of adding <code>f</code> at the end of the variable?</p>
<p>EDIT: So you're saying if I initialize a variable with <code>200.03</code> it won't initialize it as a floating point but if I were to do so with <code>200.03f</code> it would? If not where does the f become useful then?</p>

Cannot retrieve Selected option value
|
<p>I can able to get the selected option value in onchange event. But, when clicking the ok button in the same page , I can't get the value selected. Please help me.. </p>
<p>Code is as follows: </p>
<pre><code><select id ="userstoassign">
<option value="s1">S1</option>
<option value="s2" selected="selected">S2</option>
<option value="s3">S3</option>
</select>
<input type="button" name="ok" id="ok" value="ok"/>
$("#ok").live('click', function(){
var username= $("#userstoassign option:selected").val();
alert(username);
});
</code></pre>
<p>Note: In onchange event, I can get the selected value. Temp fix is I'm getting that value in onchange event in a variable and will use it in onclick event. Even in onchange event I'm getting default value if I use the code "$("#userstoassign option:selected").val();"</p>
<pre><code> $('#userstoassign').live('change',function(){ selectedUser=this.value;
alert(selectedUser);

Using a std::vector<char> as a variant

<p>I want a simple variant with </p>
<ul>
<li>minimal overhead</li>
<li>that can be passed to functions written in the C language</li>
</ul>
<p>so I decided to use a std::vector like this<br></p>
<pre><code>typedef std::vector<char> SimpleVariant;
SimpleVariant data;
</code></pre>
<p>(1) store a std::string<br></p>
<pre><code>for(std::string::iterator it = str.begin(); it != str.end(); ++it)
{
data.push_back( *it );
}
data.push_back('\0');
</code></pre>
<p>(2) store a double</p>
<pre><code>data.resize(64);
std::sprintf(&data[0], "%.*g", 20, val);
</code></pre>
<p>(3) get a string<br></p>
<pre><code>std::string str = std::string( m_data.begin(), m_data.end() );
</code></pre>
<p>(4) get a double<br></p>
<pre><code>double dbl = boost::lexical_cast<double>(&data[0]);
</code></pre>
<p>Is this a reasonable approach given my requirements? Is there lightweight variant that I can use instead of trying to reinvent the wheel? <br>
I am aware of boost::variant and boost::any they are too heavyweight for my needs</p>

How can I track the reason why an ASP.NET Session times out?
|
<p>I'm trying to track down an issue on an ASP.NET v3.5 application where the <code>HttpSession</code> times out before its (default) 20 minutes. We're seeing behaviour where the session is lost only a few minutes into a session, at random and with no discernible cause such as unhandled exceptions. As far as I can tell, the ASP.NET worker process is not dying, otherwise that would have explained the dropped session.</p>
<p>What approach should I use to monitor when the session is dropped? Is there some event I can listen to, or some other hook in the <code>System.Web</code> namespace?</p>
<p>Also, can someone confirm that the countdown to expiration is reset by web activity? That is, the session's lifetime gets reset to the (default) 20 minutes each time the web client makes an HTTP GET or POST?</p>

PHP zip_open what temporary directory is it using for the temp files
|
<p>How can I find out the temporary directory that zip_open is using to temporary hold the
extracted files.
Is there a way to extract this from a resource handler getrieved from this:</p>
<pre><code> $zip = zip_open($src_file)
while ($zip_entry = zip_read($zip))
</code></pre>
<p>$zip_entry - being the zip resource handler</p>
<p>I suspect it is not using the php temporary directory, that I can check from </p>
<pre><code>sys_get_temp_dir();
</code></pre>

How To Make A Rounded Segmented Button Group On The iPhone
|
<p>So I'm looking how to make a similar button group for an application on the iPhone that looks like the buttons in the Yelp About Me page or Twitter for Mobile application on the profile pages. Are these just a segmented controller? Or possibly images? I can't really find any resources for this online, so I figured I'd ask here. Let me know! Thanks!</p>

Android onBackPressed/onUserLeaveHint
|
<p>Just a bit of advice needed really. I have an Activity running with my game in it and when the user presses the Back button it will exit back to the Main Menu using the onBackPressed() method, but I am also overriding the onUserLeaveHint() to do the same action if the Home Button is pressed or a phone call is received. However this method is also called when the Back button is pressed, meaning that the Main Menu Intent is called twice with one on top of the other.</p>
<p>If anyone has an idea about how to get around this issue or a better way of handling the two events it would be much appreciated.</p>
<p>Thanks.</p>

PHP get the calling object on a method
|
<p>Is there a way to get the actual calling object from a method?</p>
<p>For example, I have a scenario where I do something like this:</p>
<pre><code>$user = new User;
$user->setName('name');
$user->save($user);
</code></pre>
<p>Instead of passing the $user to the save method, it would be nice to just have it get the calling object information.</p>
<p>I know I can do <code>get_called_class()</code> but that doesn't return the actual object's data. I was also looking at PHP's Reflection classes but didn't see anything exactly right.</p>
<p>Any ideas?</p>
<p>Thanks!</p>

Android Softkeyboard not showing up when form field is focused via JS
|
<p>So I'm using the jQuery plugin, RSV(real simple validation) because the client would like to use alert boxes as opposed to inline alerts for the form validation.
This site is for mobile browsers.
The problem I'm running into is that when there's an error, an alert dialogue comes up to tell the user about their offense. When the alert is closed, the offending field is focused.
The problem with the android is that the soft keyboard doesn't show up.
Here's the code that generates the error handling:</p>
<pre><code>function timsErrorFunction(f, errorInfo)
{
for (var i=0; i<errorInfo.length; i++)
{
// errorInfo[i][1] contains the error string to display for this failed field, e.g.
alert(errorInfo[i][1]);
// errorInfo[i][0] contains the form field node that just failed the validation, e.g.
errorInfo[i][0].focus();
errorInfo[i][0].style.color = "red";
}
return false; // always return false! Otherwise the form will be submitted
}

Best practices for web application workflow?
|
<p>Note: By workflow i'm not referring to workflow technology, such as Workflow foundation. </p>
<p>All too often I find myself being required to design pages that flow through a series of steps. </p>
<p>1) Select from a set of options. Submit.
2) Populate a page with results. Make changes. Submit.
3) Do something based on the previous results. Submit.
4) Confirm previous actions. Submit.
5) Goto 1.</p>
<p>An ecommerce site with shopping cart would be a textbook example of this.</p>
<p>Now, there are any number of ways to deal with this. My question is, what is the recommended way to do it in asp.net? In PHP or ISAPI I would just use standard html controls, get the post data and do stuff with it, each on a different page. </p>
<p>ASP.NET seems to be more oriented towards single page solutions. Do your work, postback to yourself, then display your results in the same page.. moving along until the end, using something like a MultiView or UpdatePanels to do the job. But the key being, you don't postback to another page.</p>
<p>Now I understand that Microsoft has added cross-page postbacks to .NET in recent versions, but this seemss less baked and kind of cumbersome. It's difficult to work with data that was posted back unless you expose it via properties or something from your previous page.</p>
<p>How do you handle the scenario I layed out above? Do you use a multi-view or updatepanel and do it all in one page? Or do you do it in several pages? What is your best practices in this regard? Do you have any specific designs you tend to use? How do you go about structuring the sites workflow?</p>

simple constructor issue
|
<p>Lets say I have this class called class1, class1 contains one default constructor and one that takes one parameter (say a string for example). Inside that constructor I set up a variable, lets call it "string var". I want var to get the value from the string that I passed to the constructor while creating that object, but I want to be able to use var outside of the constructors scope, is that possible? since constructors doesen't return values and whatnot.</p>
<p>To clarify here is a code example of what I want to do:</p>
<pre><code>class class1
{
public class1(string songPath)
{
System.Media.SoundPlayer songPlayer = new System.Media.SoundPlayer(songPath);
}
//here I want to use my songPlayer I created with the passed string as songPath
}

Binary "[" error on structure while using for function

<p>I'm trying to make a Q3BSP map information debugger.</p>

printf( "Texture id %d\n", i );
printf( "\tTexture name %s\n", Texture[i].name );
printf( "\tTexture flags %d\n", Texture[i].flags );
printf( "\tTexture contents %d\n", Texture[i].contents );
}
</code></pre>
<p>But this kind error appears to show up:</p>
<blockquote>
<p>error C2676: binary '[' : 'Q3BSPTexture' does not define this operator or a conversion to a type acceptable to the predefined operator</p>
</blockquote>
<p>Here is the Q3BSPTexture structure:</p>
<pre><code>typedef struct {
char name[64]; // Texture name.
int flags; // Surface flags.
int contents; // Surface contents
} Q3BSPTexture;
</code></pre>
<p>I'm suspecting that the structure hasn't the limit setted like char <strong>[32]</strong></p>

C++ file read fails after 685 successes
|
<p>I'm working on a piece of C++ through which I read a file. Currently there are only two places (inside a function) where the file is being read from using the .get() method.</p>
<p><strong>1)</strong> The first place is rarely used (in all about six times)</p>
<p><strong>2)</strong> The second place is heavily used. I have a for loop with the .get() method called inside, instead of the .ignore() method (with no loop) - I wanted to quantify how many times I could read from the file before the file failed.</p>
<p>I added a variable which incremented every single time the .get() method was called. It always fails on the 685th call for some reason.</p>
<p><strong>Additionally</strong>, if I eliminate the second place, calling the .get() method once I've .ignore()'d past the 684th character will still cause the file to fail. So it isn't the amount of times .get() is called that is causing the fail - its the place in the file being read from.</p>
<p>There is absolutely NO WAY it could have reached the EOF. 685 characters is < 1% of the file.</p>
<p>I checked the 685 character in the file with a hex editor and there didn't seem to be anything special or remarkable about it.</p>
<p>So why is the file failing? I don't want to show you the exact code, but if you need clarification I can try to elaborate a little more, as I realize this is still a little vague.</p>
<p>Thanks in advance.</p>

Android INSTALL_FAILED_UID_CHANGED

<p>I have been doing debugging on Android using my Nexus 4, however I recently encountered this error here. After doing some research on this error, it seems to be an issue with the app not being deleted properly. The app I am debugging runs fine on my other Android devices as well as the emulators, this error is only occuring on my Nexus 4. I plugged my device into computer, and have tried deleting the data/data folders but I am still getting the same issue. I also checked settings-apps to check it was definitely uninstalled. </p>
<p>Does anyone have any idea how to resolve this issue? According to some users, I need root access to properly delete data/data, is this true? Or is there another way around this?</p>

Generate random word ( from two known words )

<p>SO I can do this with numbers:</p>
<pre><code><?=number_format(mt_rand(0,1));?>
</code></pre>
<p>What I want to do is echo instead of 0 or 1</p>
<p>the words <strong>firstclass</strong> or <strong>secondclass</strong></p>
<p>Because I cannot use numbers as class identifiers ( css ) So essetinally, this is just for displaying random stuff within a list and prepending the class identifier with either firstclass or secondclass.</p>
<pre><code>.firstclass {display:none;}
</code></pre>
<p>I am not ace with php, so I guess I need to set up an array, and somehow attribute:</p>
<p>0 = firstclass
1 = secondclass </p>
<p>within the array, so that i can get my little test script working.</p>

How to distinguish Click event from touch event in onTouchEvent method when app is running in device?
|
<p>I override the onTouchEvent method of Activty. In this method i would like to listen to actions: touch and click and give them two different reactions. The problem is when i test my app in emulator, everything works fine. But not in device. As in device, when i just click a button, i don't just get ACTION_DOWN and ACTION_UP but a few ACTION_MOVE signals after ACTION_DOWN.</p>

hiding the tr tags and showing them after the uncheck

<p>I posted <a href="http://stackoverflow.com/questions/3714242/how-do-i-fade-out-all-the-other-tr-tags-with-jquery">this question</a> about 15 minutes ago and I got some good responses. But one thing i forgot is if the user unchecks the checkbox all the others that were hidden need to reappear again.... any ideas</p>
<p>i was using this</p>
<pre><code>$(function() {
$('input:checkbox').click(function() {
$(this).closest('tr').siblings().each(function() {
$(this).hide("slow");

jquery animating dynamic height div
|
<p>quick question. im trying to animate a few things with jquery and although its working, this is the problem im having.</p>
<p>well first heres the code:</p>
<pre><code>$(document).ready( function(e){
// vars
var question = $('#faqQues');
var answer = $('#faqAns');
var ansCont = $('#faqAnsCont');
question.click(function(){
if(answer.css("display") != "none"){
answer.animate({'height':0}, 500, hmm);
function hmm(){
answer.css("display","none");
}
} else {
answer.css("display","block");
answer.animate({"height":'100'},500);
}
});
});
</code></pre>
<p>essentially all i want to do be able to click something and it animate its height(up down).
the problem comes in on this code block</p>
<pre><code>else {
answer.css("display","block");
answer.animate({"height":'100'},500);
}
</code></pre>
<p>specifically on this line</p>
<pre><code>{"height":'100'}
</code></pre>
<p>what i want to happen is that it animates back to the divs default height. I dont want to
add a number <code>(like the 100 above)</code> height because the divs inner content is always going to change hence the dynamic height but if i remove the height, it breaks. Ive tried a few other things including something like maybe</p>
<pre><code>.animate({"height":'**divNameHere**.height()'},500);
</code></pre>
<p>but although it dont get errors, it doesnt work either lol.</p>
<p>So here i am asking for help. what changes do i need to make to this so that it animates back to whatever that divs height is without directly putting in a number?</p>
<p>Any Tips, code, links etc i'll gladly appreciate</p>

jQuery - What's the most efficient way to filter out first and second elements found?
|
<p>I am using the latest and greatest jQuery.</p>
<p>I will have a ten divs with content. On page load, I need to close all divs except the first and second. Only the first two divs I want visible. </p>
<p>Under those visible two divs are "show more" and "show less" buttons. When the user clicks the show more button, all divs will slide down. When the user clicks the show less button, all but the first two divs should slide up. </p>
<p>I know how to get at the first, the last, but I don't know how to filter out the first and the second element. I know I could get this done with more tinkering than I have already done, but I want to know the most efficient and readable way of getting it done. Can you help me? </p>
<p>One page load, this should go through and close all but the first and second divs:</p>
<pre><code>$(".BrandParagraph").each(function() {
// should close all but first and second
$(this).slideUp;
});
$(".ShowMore").click(function() {
// slide down all
$(".BrandParagraph").slideDown();
});
$(".ShowMore").click(function() {
// slide up all but first and second
$(".BrandParagraph").slideDown();

JavaScript Encapsulation
|
<p>So I've been looking into full development object oriented JavaScript practices, and wonder about the following examples.</p>
<p>As I understand it, (and it makes sense to me) that the following 'secret' field is 'private' :</p>
<pre><code>var MyObject = function() {
var secret = 'sshhh';
this.getSecret() = function() {
return secret;
}
}
</code></pre>
<p>and this is because the field secret has function scope that the inner function can access, but nothing outside ... so far so good.</p>
<p>But I've seen the following around (and especially in Douglas Crockford's book) : </p>
<pre><code>var MyObject = function() {
var secret = 'sshhh';
return {
getSecret : function() {
return secret;
}
}
}();
</code></pre>
<p>and was wondering what the difference is, why is it better? I understand that in this case we're not even returning the same object that the private field exists in, but don't see a huge benefit as you can't access the field directly either way.</p>

Java: how to write formatted output to plain text file
|
<p>I am developing a small java application. At some point i am writing some data in a plain text file. Using the following code:</p>
<pre><code>Writer Candidateoutput = null;
File Candidatefile = new File("Candidates.txt"),
Candidateoutput = new BufferedWriter(new FileWriter(Candidatefile));
Candidateoutput.write("\n Write this text on next line");
Candidateoutput.write("\t This is indented text");
Candidateoutput.close();
</code></pre>
<p>Now every thing goes fine, the file is created with the expected text. The only problem is that the text was not formatted all the text was on single line. But if I copy and paste the text in MS Word then the text is formatted automatically.</p>
<p>Is there any way to preserver text formatting in Plain text file as well?</p>
<p>Note: By text formatting I am referring to <code>\n</code> and <code>\t</code> only</p>

Change "HUE" of an image with PHP GD Library?
|
<p>I'd like to change the "hue" of an image using the PHP image processing functions. Which is the correct filter to apply?</p>
<p>Note: I'm from a photoshop background, so in the event my interpretation of "hue" is different from others, here's what I mean...</p>
<p>In photoshop, you can use the "Hue" filter to change the color of an image without actually affecting the design of the image.</p>
<p>I'm currently using the function below to recolor my images, but the function fails to meet my needs due to the fact that it completely repaints the image, losing the design.</p>
<pre><code> function set_theme_color_header($hex)
{
$info = hexToRGB($hex); //utility function that converts hex to rgb
$token = "header.gif";
$img = imagecreatefromgif("header-template.gif";
$color = imagecolorallocate($img, $info["red"], $info["green"], $info["blue"]);
imagecolorset($img, 0, $info["red"], $info["green"], $info["blue"]);
imagegif($img, $token);
