Problem adding custom view to navBarItem
|
<p>Can anyone explain to me why the code below does not work correctly on iOS 3.1.3? On 4.0 it works great however on earlier versions the image is not respecting the size of the frame and is displaying in its original size leaving a huge image where my navItem should be???</p>
<pre><code>flipView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
flipView.contentMode = UIViewContentModeScaleAspectFit;
detailFlipButton = [UIButton buttonWithType:UIButtonTypeCustom];
detailFlipButton.frame = CGRectMake(0, 0, 30, 30);
[detailFlipButton setImage:self.myImage forState:UIControlStateNormal];
detailFlipButton.imageView.contentMode = UIViewContentModeScaleAspectFit;
[detailFlipButton addTarget:self action:@selector(flipAction) forControlEvents:UIControlEventTouchUpInside];
[flipView addSubview:detailFlipButton];
UIBarButtonItem *flipBarButton = [[UIBarButtonItem alloc] initWithCustomView:flipView];
self.navigationItem.rightBarButtonItem = flipBarButton;
[flipBarButton release];
</code></pre>
<p>Basically i am trying to accomplish something similar to the navItem in the top right corner of the iPod app which flips the view when tapped.</p>

Why dont i have rights on uploaded file?
|
<p>I've just created a php snippet that allows me to upload pictures. Im working on my personal pc that runs Windows7, IIS7 and PHP.</p>
<p>The wierd thing is that Im allowed to upload and it works great, but if i go to the folder: <code>c:\inetpub\wwwroot\imgupload\uploads</code> and try to view the image then im now allowed because i dont have any rights. Adding my user to file rights solves the problem but thats a bit silly aint it? im using php's <code>move_uploaded_file()</code></p>
<p>any thoughts?</p>

Any way to apply onclick events to a large list of li dynamically?

<p>Ok, I have an unordered list like so:</p>
<pre><code><ul id=list>
<li> Item 1 </li>
<li> Item 2 </li>
<li> Item 3 </li>
<li> Item 4 </li>
<li> Item 5 </li>
</ul>
</code></pre>
<p>Is there any simple way of creating onclick events for each of the individual li's?</p>
<p>Here's my objective... I have CSS setup like so:</p>
<pre><code>#list li {...some styles here...}
#list li:active {...change background color and font color on click...}
</code></pre>
<p>So again, any simple way of doing this? I know I can achieve it by simply adding an onclick event to each of the individual li's, but any smart way of doing this?</p>
<p>(For clarification - I'm actually going to be using an 'ontouchstart' event for mobile webkit)</p>

Adding and Removing an active class

<p>I know this should be simple and has been covered a million times already but I just can;t seem to get it to work.</p>
<p>It's your basic script that makes the last link you clicked in a list become the 'active' link my adding the 'active' class to it.</p>
<p>HTML</p>
<pre><code><ul id="projectsList">
<li><a href="#" class="activeProject" id="portoftyne">Port of Tyne</a></li>
<li><a href="#" id="eaga">Eaga</a></li>
<li><a href="#" id="gong">Gong</a></li>
<li><a href="#" id="nufc">NUFC</a></li>
</ul>
</code></pre>
<p>jQuery</p>
<pre><code> $(document).ready(function() {
$('#projectsList a').click(function(){
$('.activeProject').removeClass('activeProject')
$(this).addClass("activeProject");
});
});
</code></pre>
<p>Should work, doesn't at all.</p>

Android / layout: how to create a header-content layout
|
<p>How do I go about creating the following layout in Android?</p>
<p>I want a "header", that is, a header that stays the same at all times. The only thing that should change is the area below the header.</p>
<p>Think of it as a webpage, where the content-area is where its all happening =)</p>
<pre><code>+--------------------+
| H E A D E R |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
</code></pre>
<p>Sure, its easy enough to create a LinearLayot, add a View on the top and then another view below that - tada! But what Im after is how you "set up" or design the project so its easy to just change whats in the Content.</p>
<p>What I <b>really</b> would like is to be able to "swipe" (see <a href="http://stackoverflow.com/questions/1959106/android-how-to-create-different-screens-and-nav-between-them-using-touch-and-d">here</a>) the area and then just "roll in" a new View/thing in the Content-area, but keep the same header.</p>
<p>What I really miss is a comprehensive library of layoyt-examples...</p>

$src_filename = substr($link_filename, 0, strrpos($link_filename) - 4);
echo $src_filename;

$dateplayed = '2011-01-17 11:01:44';

{
HRESULT hr = S_OK;
UINT er = ERROR_SUCCESS;
LPWSTR szValueBuf = NULL;

ExitOnFailure(hr, "Failed to initialize");
WcaLog(LOGMSG_STANDARD, "Initialized.");
hr = WcaGetProperty(L"INSTALLLOCATION",&szValueBuf);
ExitOnFailure(hr, "failed to get Install Location");
wcstombs(szInstallPath, szValueBuf, 260);
// I would like to strip back the trailing backslashes
// and re add the property to my MSI
hr = MsiSetProperty(hInstall, "INSTALLLOCATION", szInstallPath);
ExitOnFailure(hr, "failed to set the install location");
LExit:
er = SUCCEEDED(hr) ? ERROR_SUCCESS : ERROR_INSTALL_FAILURE;
return WcaFinalize(er);
}

<p><code>szInstallPath</code> could have either none, one or two backslashes, I need to remove backslashes if there are any. Can anyone point me in the right direction please for good website tutorials or anything?</p>

<p>I was just wondering is there any difference between using the expression </p>
<pre><code>if (threadInfo != NULL)

<p>what is said above.
While reading the first one reads " If NULL not equals to ThreadInfo" and the second one reads "If threadInfo not equals to NULL". To me the second one makes more sense. </p>

Back button affect on elements created dynamically by jquery

<p>I'm developing a page that makes extensive use of jQuery to dynamically create elements on the page.</p>
<p>After I post through to the next page and then click the back button, all the dynamically created elements disappear when using Chrome and IE.</p>
<p>However, in Firefox and Safari, the elements remain on the page.</p>
<p>How do I get Chrome and IE to display the same behavior as Firefox and Safari?</p>

GDI+ and system graphics cards

<p>From my research I have seen that <code>GDI+</code> (if i am wrong correct me please) is used by <code>Graphics</code> to draw various object, but also to my knowledge I am unsure if it utilizes the systems graphics card? If it does not could someone please lead me to a way that I can tell it to utilize the graphics cards many features, like the shader etc, or at-least how to code my own DirectX, OpenGL engine? </p>

Iterators and multi-dimensional vectors?
|
<p>So, I am trying to build a two-dimensional vector that will hold indexes for selecting tiles from a tileset.</p>
<p>An iterator in one dimension is simple enough:</p>
<pre><code>std::vector<int> vec;
std::vector<int>::iterator vec_it;
for(int i=5; i>0; --i){
vec.push_back(i); }
//prints "5 4 3 2 1 "
for(vec_it = vec.begin(); vec_it != vec.end(); ++vec_it){
std::cout<<*vec_it<<' ';
}
</code></pre>
<p>However, I'm running into trouble when adding the second dimension. Here's the code that <b>doesn't</b> work:</p>
<pre><code>std::vector<std::vector<int> > vec(5);
std::vector<std::vector<int> >::iterator vec_it;
std::vector<int>::iterator inner_it;
for(int i=0; i<5; ++i){
vec[i].assign(5, 0);
}
for(vec_it = vec.begin(); vec_it != vec.end(); ++vec_it){
for(inner_it = *vec_it->begin(); inner_it != *vec_it->end(); ++inner_it){
std::cout<<*inner_it<<' ';
}
std::cout<<std::endl;
}
//should print:
//0 0 0 0 0
//0 0 0 0 0
//0 0 0 0 0
//0 0 0 0 0
//0 0 0 0 0
</code></pre>
<p>The compile fails with a nearly-incomprehensible error where I try to do <code>inner_it = *vec_it->begin()</code>, so I suppose my question is, how badly did I screw up?</p>

Add method onto a single jQuery node
|
<p>Say that I have two html nodes like this:</p>
<pre><code><div class='node a'>one</div>
<input class='node b' value='two'>
</code></pre>
<p>and I'd like to add a method for $('.node.a'), but not for node b. What I'd really like to do is something like this:</p>
<pre><code>$('.node.a').addMethod('val', function() {
return $('.node.b').val();
});
alert($('.node.a').val()); // alerts 'two'
</code></pre>
<p>Clearly I don't want to override the 'val' method for every jQuery node. Is it possible to do this?</p>
<p><strong>* UPDATE *</strong></p>
<p>As per mgibsonbr's suggestion, I wrote a jQuery plugin to do this for me. Instead of using jQuery data method, I only run different functionality if the node in question is the one being called. This means that this form will not work for jquery lists that match multiple html nodes. Here it is:</p>
<pre><code>// overrides a method thats supposed to be called on a single node (a method like val)
$.fn.overrideNodeMethod = function(methodName, action) {
var originalVal = $.fn[methodName];
var thisNode = this;
$.fn[methodName] = function() {
if (this[0]==thisNode[0]) {
return action.apply(this, arguments);
} else {
return originalVal.apply(this, arguments);
}
};
};

Comparing values of each integer within a range
|
<pre><code>n= int(raw_input(" Enter a number"))
i = 0
length = 0
maxLength = 0
for i in range(1, n - 1):
if length > maxLength:
maxLength = length
i = i + 1
*run other program which gets value*
code
code
code
print i
print maxLength
</code></pre>
<p>So, what I have so far is a program that of course gets a value, what I need to do with this value, is create a loop that will compare the value of each integers value within range of integers between 1 and the user input or "n", than output the integer with the highest value, and what that value is within the range.</p>

Does it make sense to use std::uninitialized_fill() with any allocator?
|
<p>Does it make sense to initialize memory with <code>std::uninitialized_fill()</code> in a library when an allocator passed as argument by the user has been used to get the memory itself? I ask this because an allocator is supposed to have provide its own <code>construct()</code> method (other than the <code>allocate()</code> method), the implementation of which might differ from the standard one, so probably <code>std::uninitialized_fill()</code> is not always appropriate in all the cases.</p>
<p>To be precise, my doubts come from the C++ book written by Stroustrup (appendix E "Standard-Library Exception Safety", section E. 3.1), in which the author gives a possible implementation of a <code>template<class T, class A> vector<T,A>::vector(size_type n, const T& val, const A& a)</code>: the allocator a is used to get the memory for the vector, then <code>std::uninitialized_fill()</code> is used to initialize the obtained memory.</p>
<p>He also gives the implementation of <code>std::uninitialized_fill()</code>, which internally uses the standard placement new to initialize the the memory, but there is no longer evidence of the <code>construct()</code> method of the allocator passed as argument to the vector constructor.</p>

How do I sync application data between an iPhone and another computer?
|
<p>I'm working on an iPhone application that would allow viewing and editing of data that I want to keep in sync with a desktop application. I don't see anything in the SDK that directly addresses data synchronization, nor can I find anything that allows my to "hook" into the iTunes sync process.</p>
<p>I could do something kludgy like hiding the data in a photo or address book entry, but that just seems like a bad idea. I could use WebDAV or HTTP to get/put data to a server, but it makes the application more complicated.</p>
<p>I guess I was expecting this to be a common use-case for iPhone apps (syncing arbitrary application data between a desktop and the iPhone) and that there would be a set of APIs in the SDK that cover this. Maybe there is and I just can't find it.</p>

jquery selector for selected siblings of a common parent

<pre><code>$( ":parent .divider", this ).attr( "src", "images/navbar-menu-hover-right.png" );
</code></pre>
<p>Which doesn't seem to work. To get the left side, I need to go up a level, find the previous sibling, then get its .divider (though I'm sure there are several alternatives).</p>

iPhone:iPhone Configuration profile email setting unable to edit on the device?

<p>I have an iPhone program, which picks an iPhone Configuration profile which has set-up for an email(pop). My program downloads this profile and installs on the device via safari browser to create the new email account on the device. The issue is, after installed the profile successfully, if i want to manually edit the account information(for ex: username, email address) from “Settings->Mail, Contacts, Calendars” mail account screen on the device, i'm not allowed to edit except 'password' and 'description' field. Is it restricted by iOS? If we install any Configuration Profile on the device which creates mail box, then we can't edit the account information(for ex: username, email address) from “Settings->Mail, Contacts, Calendars” mail account screen on the device? </p>

Enum with methods for functionality (Combine Class / Enum)
|
<p>I may miss some sort of point here, if that's the case - please include that discussion as a part of my question :).</p>
<p>This is a shortened down and renamed sample of a working code. The GetTicks(..) is a single sample, which could be any sort of functionality (value of <code>> 0 < 9</code> should return a specific Enum a.so).</p>
<pre><code>public static class Something
{
public enum TypeOf : short
{
Minute = 2, Hour = 3, Day = 4, ........
}
public static long GetTicks(Something.TypeOf someEnum)
{
long ticks = 0;
switch (someEnum)
{
case Something.TypeOf.Minute:
ticks = TimeSpan.TicksPerMinute;
break;
case Something.TypeOf.Hour:
ticks = TimeSpan.TicksPerHour;
break;
....
}
return ticks;
}
}
// This class is called from anywhere in the system.
public static void SomeMethod(string dodo, object o, Something.TypeOf period)
{
// With the design above
long ticks = Something.GetTicks(period);
// Traditional, if there was a simple enum
if (period == Something.Day)
ticks = TimeSpan.FromDays(1).Ticks;
else if (period == Something.Hour)
ticks = TimeSpan.FromHours(1).Ticks;
}
</code></pre>
<p>The idea is to collect functionality that concerns a enum, near as possible to the enum itself. The enum is the reason function. Also I find it easy and natural to look for such functionality near the enum. Also it's easy to modify or extend.</p>
<p>The drawback I have, is that I have to state the enum more explicit <code>Something.TypeOf</code>. The design may look no-standard? and would apply if the enum was for internal use in the class.</p>
<p>How would you do this more nice?
I tried abstract, base inheritance, partial. None of them seem to apply.</p>

perfekt editor with a black theme for windows
|
<p>like many of you, I code my javascript projects in eclipse because it offers hundrets of different views and optional built in svn/git support </p>
<p>after working for hours with eclipse my eyes really feel punished because of the bright white workspace windows. also the code completion lacks many things.. even now that JS is a really etablished language. and also the eclipse javascript validator fails so many times, throwing annoying error pop ups.</p>
<p>at first i tried to find another editor with git/svn built in support, that also comes with a black theme. i couldnt find anything useful here.
secondly i became aware that there is an eclipse theming plugin and another one for fullscreen. both are a good start, but it still looks like a hacky solution.. </p>
<p>it seems you cant theme the eclipse frames and things like the code sync are also no themable, so you end up with black marks on a black background.</p>
<p>is there something between VIM and eclipse that you are maybe aware about? even if i would have to do my svn / git via console/tortoise, but i cant stand the overcrowded looks of eclipse any longer. </p>

Android: Background music is playing while lock screen is on
|
<p>If my activity is running in the foreground and the display is turned off and then turned back on again the background music starts to play again before the screen is unlocked. The background music is paused in onPause() and continues to play in onResume(). So when the app is pushed to the background the music stops.
Is there a way to prevent the music from playing while the lock screen is on?</p>

Resume Activity with back button
|
<p>I have an application I am creating with a DashboardActivity & a SettingsActivity. On the dashboard, I have one object displayed, but when I go into settings, I want to be able to select/deselect X options. Once the user clicks the back button, I save that data locally and to the server. Once the phone receives a success message from the server that it was stored properly, I want to reload the dashboard. </p>
<p>I thought I would do this with the onPause and onResume, but they are called when the DashboardActivity is first created. What would be the best way to reload the dashboard by calling my web service after the settings were saved to the server? Here is what I am doing when the back button is hit</p>
<pre><code>@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
//Save data to the server once the user hits the back button
if ((keyCode == KeyEvent.KEYCODE_BACK)) {
SchoolSearchActivity.this.divisionProxy = new DivisionProxy(SchoolSearchActivity.this.saveUserDivisionHandler);
SchoolSearchActivity.this.divisionProxy.submitUserDivisions(SchoolSearchActivity.this.userDivisions, SchoolSearchActivity.this.user_id);
//SchoolSearchActivity.this.finish();
//Toast.makeText(SchoolSearchActivity.this, "Divisions Saved",Toast.LENGTH_LONG).show();
}
return true;
}
</code></pre>
<p>The above opens an HTTP connection, and when the response is received, the handler processes the response. I want to:
1) submit the data to the server
2) return to the previous activity
3) show a progress dialog until the response from #1 returns (response handler is in the settings activity; and we are now in the dashboard activity)
4) "refresh" the dashboard</p>
<p>What is the best way to accomplish this so I can just resume the dashboard as it was. Like I said, when I overwrite the onResume method, it is called when the activity is first created. I was considering putting my webservice call in onResume, so it's called once everytime you make it to the Activity, but it doesn't seem like the cleanest way.</p>
<p>What would you suggest for 1-4?</p>

networkStream.Read is blocking

<p>I'm writing a simple application which will connect with a server. However I want to send simple chat commands aswell (see <code>Console.ReadLine</code> below). However this script won't get to <code>string Message = Console.ReadLine();</code> since it's blocked at <code>bytesRead = clientStream.Read(message, 0, 4096);</code>.</p>
<p>I want to continue this script, but if there's bytes incoming, it should process them (like it's doing now) and if no bytes are incoming, it should go through the script and wait for user input). How can this be achieved?</p>
<pre><code> TcpClient tcpClient = (TcpClient)client;
NetworkStream clientStream = tcpClient.GetStream();
byte[] message = new byte[4096];
int bytesRead;
while (true)
{
bytesRead = 0;
try
{
// Blocks until a client sends a message
bytesRead = clientStream.Read(message, 0, 4096);
}
catch (Exception)
{
// A socket error has occured
break;
}
if (bytesRead == 0)
{
// The client has disconnected from the server
break;
}
// Message has successfully been received
ASCIIEncoding encoder = new ASCIIEncoding();
// Output message
Console.WriteLine("To: " + tcpClient.Client.LocalEndPoint);
Console.WriteLine("From: " + tcpClient.Client.RemoteEndPoint);
Console.WriteLine(encoder.GetString(message, 0, bytesRead));
// Return message
string Message = Console.ReadLine();
if (Message != null)
{
byte[] buffer = encoder.GetBytes(Message);
clientStream.Write(buffer, 0, buffer.Length);
clientStream.Flush();

Should I keep a copy in memory of the information being displayed?

<p>When editing a value, generally I have to validate and do some other tasks, depending on the value that's being edited.</p>
<p>Should I keep a copy as array of objects in memory and use their methods or should I store all the information I need (type of value, id, etc) somewhere in the html table (as attributes or hidden inputs) and get them using several functions?</p>
<p>Which would be best practice?
Is it risky to have many objects stored in memory (taking into account memory usage of the browser)?</p>
