<p>When I Run My Application After Some Second This Exception Occurred. what is exception and How I Can Handle This Exception </p>
<blockquote>
<p>The CLR has been unable to transition from COM context 0x647f10 to COM
context 0x648080 for 60 seconds. The thread that owns the destination
context/apartment is most likely either doing a non pumping wait or
processing a very long running operation without pumping Windows
messages. This situation generally has a negative performance impact
and may even lead to the application becoming non responsive or memory
usage accumulating continually over time. To avoid this problem, all
single threaded apartment (STA) threads should use pumping wait
primitives (such as CoWaitForMultipleHandles) and routinely pump
messages during long running operations.</p>

Call php class method from string with parameter
|
<p>I am having trouble calling a <strong>class method</strong> from a string in PHP. Here's a simple example. Once I get this working I'll be using a variable as the method name.</p>
<p>Here's how I'd be calling the method normally:</p>
<pre><code>$tags_array = $this->get_tags_for_image($row["id"]);
</code></pre>
<p>Here's how I'm trying but getting an error:</p>
<pre><code>$tags_array = call_user_func('get_images_for_tag', $row["id"]);
</code></pre>
<p>I must be missing the scope but I can't figure out how to call the method.</p>
<p>----EDIT
Figured out that this calls the method but <strong>$row</strong> is undefined now I believe</p>
<pre><code>$tags_array = call_user_func(array($this, 'get_images_for_tag'), $row["id"]);
</code></pre>
<p>Full code block:</p>
<pre><code> $images = call_user_func(array($this, 'get_images_for_tag'), $filter);
foreach ($images as $row){
$tags_array = call_user_func(array($this, 'get_images_for_tag'), $row["id"]);
foreach ($tags_array as $tag_row){
$tags_array[] = $tag_row["tag"];
}
$image_array []= array (
'url' => $this->gallery_path_url . '/'. $row["name"],
'thumb_url' => $this->gallery_path_url . '/thumbs/' . 't_'. $row["name"],

max = arr[1]
min = arr[0]

madmax([123, 2, 345, 153, 5, 98, 456, 4323456, 1, 234, 19874, 238, 4])

Can I create an activity for a particular task without that task coming to the foreground?
|
<p>Here's my use case:<br>
The app starts at a login screen. You enter your credentials and hit the "Login" button. Then a progress dialog appears and you wait for some stuff to download. Once the stuff has downloaded, you are taken to a new activity. Exactly which activity you are taken to depends on the server response.</p>
<p>Here's my problem:<br>
If you go HOME during this login/download process, at some point in the near future your download will complete and will invoke <code>startActivity()</code>. <strong>So then the new activity will be pushed to the foreground, rudely interrupting the user.</strong> I can't start the activity before I start the download, because, as I mentioned earlier, the activity I start depends on the result of the download.</p>
<p>I would obviously not like to interrupt the user like this. One way to solve this is to refrain from calling <code>startActivity()</code> until the user returns to the app. I can do this by keeping track of the LoginActivity's <code>onStop()</code> and <code>onRestart()</code>. <strong>But I'm wondering, is there any way to create the activity while it is in the background?</strong> That way the user returns to the app and he is ready to go... otherwise he would have to wait for the new activity to be created (which could take some time because the <em>new</em> activity <em>also</em> has to download and display some data).</p>
<p><strong>Update:</strong>
Guess what? I LIED! I could have sworn that starting this activity was causing it to come to the foreground, but I went back to test it again and the problem has magically disappeared. I tested in both 1.6 and 2.0.1 and both OSes were smart enough not to bring a backgrounded task to the front.</p>

jquery/javascript object required error
|
<p>I am working in an ASP .net mvc project. The weird issue is I am running a javascript/jquery which randomly gives object required error. Sometimes it occurs but sometime it does not occur at all. What I am doing is making an explicit link click call to load a page as follows:</p>
<pre><code>function LoadPopup()
{
$("#page2link").click();
}
</code></pre>
<p>I call <code>Loadpopup()</code> in <code>$(document).ready()</code></p>
<p>After the above gets executed, page2 loads and the javascript for page2 is trying to run but I dont know why suddenly page2's javascript throws error. I don't know exactly at what line it throws error. The break point comes at <code>MicrosoftAjax.cs[Dynamicfile]</code>.</p>
<p>I am wondering why my debugger does not hit the breakpoint that I placed in page2's javascript. The stackj trace however shows a list of "java script anonymous functions" and also shows that these anonymous fucntions are called from <code>loadpopup()</code>.</p>
<p>Some more information. I am having a master page. <code>Loadpopup()</code> runs when mystartup.aspx loads, which inherits from the master page. Can anyone please help me in this regard? Please let me know if you need more detail?</p>

Package naming uniqueness for applications?

<p>When creating an android app, we need to supply a package name in the manifest.</p>
<pre><code><manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.me.foo">
</code></pre>
<p>I believe this uniquely identifies an application, such that we can't upload an app to marketplace if another app already exists with the same package name.</p>
<p>Is it possible to extend a package name though without collision? For example:</p>
<pre><code>package="com.me.foo"
package="com.me.foo.grok"
</code></pre>
<p>Will the second application be accepted by the marketplace, even though it's a substring of the first package name? </p>

<p>Something that would involve examples which could be useful in real life would be great, too, but not necessary.</p>

TypeError when retrieving random digits
|
<p>I am trying to generate a random three digit extension:</p>
<pre><code>>>> ''.join(str(x) for x in random.sample(range(1,10),3))
</code></pre>
<p>It works in the prompt. However, when I run the program, it raises a <code>TypeError: str object is not callable</code>. This is the line that I have:</p>
<pre><code> filename = hashlib.md5(imagefile.getvalue()).hexdigest() +
''.join(str(x) for x in random.sample(range(1,10),3)) + '_thumb' + '.jpg'
</code></pre>
<p>What am I doing wrong here and how would I fix it?</p>
<p>Thank you for the help. I had invoked str previously in the code, which was causing the error:</p>
<pre><code>str=""
for c in i.chunks():
str += c
...

Need comprehensive list of all native objects
|
<p>I'm getting exactly what I want when I do this <code>console.dir(this)</code> in Chrome.<br />
Is there a way to get that into an array some how?<br /><br />
So I've tried to do something like this to get started:</p>
<pre><code>for(var o in console.dir(this)) {
console.log(o);
}
</code></pre>
<p>All I get is "undefined" and it prints the list into the console again.<br /><br />
I really just need a name list of all Native Javascript Objects and their respective methods and attributes without the hassle of manually creating and maintaining a monstrous list. Ideally the solution would be a dynamically created array of everything; either flat or multidimensional array so I can iterate through it.</p>

PHP login authentication problem (beginner)
|
<p>scenario is I have different access levels on this site, I have the simple login process working for all valid users however I am now trying to seperate the different users fo different access to pages.</p>
<p>here is my code at the start of my page:</p>
<pre><code>// CHECKS IF THE USER HAS LOGGED IN
session_start();
if(!isset($_SESSION['logged_in']) || !$_SESSION['logged_in']){
header("location:index.php");
}
if(!$_SESSION['mystatus']=='1'){
header("location:access_error.php");
}
</code></pre>
<p>so basically I want this page to only be accessible by users with the access level of 1 if they are logged in however do not have the correct access level direct them accordingly.</p>
<p>at the moment it allows users who have logged in with different access levels (e.g 3) to still view this page.</p>
<p>help please. </p>
<p>many thanks,</p>

<p>I want to add an ID to a span element if the page is either 'a' or 'b'.</p>
<p>My code so far is this:</p>
<pre><code><span class="subnav2" <? if(($page == 'a') || ($page == 'b')): ?> id="active"<? endif ?>>

<p>but it only adds the class to the span when 'a' is true. What am I doing wrong?</p>
<p>The value of $page is:</p>
<pre><code><?
$path = basename($_SERVER['PHP_SELF']);
$page = basename($path);
$page = basename($path, '.php');

How to change class implementation efficiently
|
<p>I'd like to change the implementation depending on a constructor argument. Below is an example showing what I mean:</p>
<pre><code>class Device(object):
def __init__(self, simulate):
self.simulate = simulate
def foo(self):
if simulate:
self._simulate_foo()
else:
self._do_foo()
def _do_foo(self):
# do foo
def _simulate_foo(self):
# simulate foo
</code></pre>
<p>Now every call to <code>foo()</code> invokes an <code>if</code> clause. To avoid that I could bind the correct method dynamically to <code>foo</code>.</p>
<pre><code>class Device(object):
def __init__(self, simulate):
if simulate:
self.foo = self._simulate_foo
else:
self.foo = self._do_foo()
def _do_foo(self):
# do foo
def _simulate_foo(self):
# simulate foo
</code></pre>
<p>Are there any drawbacks why this should not be done or other drawbacks I'm not aware? Is this really faster?(I'm aware that inheritance is another option)</p>

equals method overrides equals in superclass and may not be symmetric
|
<p>I have below Findbugs error for my "equal" method,</p>
<blockquote>
<p>This class defines an equals method
that overrides an equals method in a
superclass. Both equals methods
methods use instanceof in the
determination of whether two objects
are equal. This is fraught with peril,
since it is important that the equals
method is symmetrical (in other words,
a.equals(b) == b.equals(a)). If B is a
subtype of A, and A's equals method
checks that the argument is an
instanceof A, and B's equals method
checks that the argument is an
instanceof B, it is quite likely that
the equivalence relation defined by
these methods is not symmetric.</p>

How to handle concurrency in an ASP.Net WebSite? (auctioneer site)

<p>My problem is very simple to clear for an more experience user I thinK. How I can handle business and database logic without opened a site or them?</p>
<p>My problem is to say directly, if nights at 3 no user is on the site, the winner (e.g.) must be set - if a page is opened or not.</p>
<p>So I need some kind of "every 2 seconds, do this method" - without opened a site.</p>
<p>My idea was a sepereate application which uses the same business and database-layer as the asp.net page and let this run at the server. Is that a good or bad idea?</p>

How to make modifications on a subset of elements in a list
|
<p>oldUsers is just a subset of allUsers and all oldUsers are made in-active in the following list. The logic currently works, but I am iterating allUsers just to get the handle of oldUser every time, before I set the active flag to false. Is there a way to pull the appropriate record and make my modifications (oldUsers and allUsers is of type <code>Set<User></code>)</p>
<pre><code>for (User oldUser : oldUsers) {
for (User user : allUsers) {
if (user.getId().equals(oldUser.getId())) {
user.setActive(false);

iPhone SDK: Store Kit: Can I host the downloads on my own server?
|
<p>I want to make an app where every single item is unique. I could not find out much information about the Store Kit in iPhone OS 3.0. Do I have to upload all these download-items to the App Store? Or can the download be made from my own server? </p>
<p>Example:
I have 10 items in my app that people can buy. They are highly exclusive, so the one who buys item X, will be the only one who's got that item. after the purchase it's not available anymore.</p>
<p>Do you think it is possible to do that?</p>

}
$photos = new Photos();
$photos->addPhoto('a', 'fsdfasd');

Join strings for series of nested lists in Python 2.7.2
|
<p>I have a series of lists that contain an integer and a nested list with multiple strings. The goal is to join the strings into one string. I have accomplished this with code that works on one list. The problem is when I try to iterate over the series of lists there is an error: "TypeError: sequence item 0: expected string, int found." I have tried to change the integer to a string, ignore items that are integers and direct the code to the nested list without success. </p>
<p>Example of series:</p>
<pre><code> [19497, ['83', 'CLM']]
[19498, ['80', 'COS', 'PAN', '83', 'CLM']]
[19505, ['79', 'MXE', 'MXN', 'MXS']]
[19507, ['83', 'CLM', 'ECU']]
[19509, ['79', 'MXG', 'MXS', 'MXT', '80', 'BLZ', 'GUA', 'HON', 'NIC']]
</code></pre>
<p>This works for one list:</p>
<pre><code> >>> q = [48, ['40', 'ASS', 'EHM', 'IND', 'NEP', 'WHM', '41', 'MYA']]
>>> q[1] = " ".join(q[1])
>>> q
[48, '40 ASS EHM IND NEP WHM 41 MYA']
</code></pre>
<p>This is what I tried for the iteration and get the type error.</p>
<pre><code> def smush(q):
'''STILL IN PROGRESS: Trying to create single string in nested list.'''
for line in q:
q[1] = ' '.join(q[1])
return q
</code></pre>
<p>I have a feeling there is a simple solution to this I have overlooked. Suggestions? </p>

javascript stream wrapper, intercept JS file contents
|
<p>In PHP there's a function called <strong>stream_wrapper_register</strong>. With that i can get the file contents of every PHP file that is about to be included. So that basically gives me control over the 'code' that will get parsed.</p>
<p>I was wondering if there's something like this in javascript too? So suppose i include my file:</p>
<pre><code><script type="text/javascript" src="js/myfile.js"></script>
</code></pre>
<p>My code in that file then sets up the stream wrapper (suppose this is available in JS too). Now i want to be able to get the file contents of every other javascript file that will be included:</p>
<pre><code><script type="text/javascript" src="js/somefile.js"></script>
<script type="text/javascript" src="js/someotherfile.js"></script>
</code></pre>
<p>But this ofcourse must happen before before the browser actually executes those files.</p>
<p>So is there a way to intercept that somehow?</p>

startActivity() but do not show it
|
<p>I have a media player app and I am trying to handle events such as when you receive a phone call. I can get it stopped properly and kill the service. Then I need to switch back to the main activity so when the user gets done with their phone call they can re-select a station to play. The problem I have is when I switch the activity with startActivity(intent) it gets shown in front of the phone dialer--this is not a good user experience.
So how can I get my app reset back to the correct activity without it showing in front of another app?</p>
<pre><code>private BroadcastReceiver phoneReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
//stop the play service
Intent stopPlayingService = new Intent(context, Play.class);
stopService(stopPlayingService);
//switch back to the main screen
Intent showMain = new Intent(context, MouseWorldRadioActivity.class);
showMain.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//showMain.addFlags(Intent.); not sure whats needed here
startActivity(showMain);

Execute PHP code when making a post in a cms
|
<p>Sorry for the vague title but it's hard to describe what I mean in a few words.</p>
<p>I made my own cms and use it for all my personal projects. On some pages I want to include a php script in the content area. I load the content simply by echoing the variable that holds the content.</p>
<p>The template file looks like this:</p>
<pre><code><div id="content">
echo $content;
</div>
</code></pre>
<p>In my CRUD I make a post containing a php snippet.</p>
<pre><code><?php echo "My name is ".$var.""; ?>;
</code></pre>
<p>Then I save it and load the page and this is what happens:</p>
<pre><code><div id="content">
echo <?php echo "My name is ".$var.""; ?>;
</div>
</code></pre>
<p>But what I want is that the php code get's executed instead of getting echoed.
Something like the Wordpress plugin Exec-PHP. Can anybody explain to me how to achieve this?</p>
<p>Thanks in advance!</p>
