3,264,180 | 3,264,181 | Field-like events and anonymous delegates | <p>When name of a field-like event <code>SomeNews</code> is used inside a class that declares this event, this name doesn't refer to the event itself, but to the anonymous private delegate <code>D</code> created by compiler, and for that reason <code>D</code> can be invoked indirectly ( inside <code>MyClass</code> ) via <code>SomeNews();</code></p>
<pre><code>class MyClass
{
public event MyDelegate SomeNews;
...
}
</code></pre>
<p>But if instead <code>MyClass</code> declares an event <code>SomeNews</code> by also specifying <code>add</code> and <code>remove</code> accessors:</p>
<pre><code>class MyClass
{
private delegate MyDelegate _someNews;
public event MyDelegate SomeNews
{
add
{
_someNews += value;
}
remove

_ someNews -= value;
}
}
...
}
</code></pre>
<p>does then even inside <code>MyClass</code> the name <code>SomeNews</code> refer to the event itself and not to the underlying delegate <code>_someNews</code>? I'm assuming this since trying to invoke <code>_someNews</code> delegate via <code>SomeNews()</code> will cause a compile-time error saying "<em>SomeNews event can only appear on the left hand side of += or -=</em>" </p>

243,451 | 243,452 | Python script problems | <p>So this is a script that I am coding for my buddies companies customer support. Basically, what it does is call using the IP phones that are in the script, it works, but with problems. Here is the code:</p>
<pre><code>import urllib, urllib2, sys
num = sys.argv[1]
print 'Calling'
phones = [
'http://phone1/index.htm',
'http://phone2/index.htm',
'https://phone3/index.htm',

'https://phone5/index.htm'

while 1:
for phone in phones:
try:
urllib2.urlopen(phone,data) # make call
urllib2.urlopen(phone+"?dialeddel=0") # clear logs
except: pass
</code></pre>
<p>The first problem is that it only calls using phone one... Right now it is setup to keep calling over and over, for debugging purposes, and I seem to only be getting calls from phone one... The second problem is that the script will not terminate. ctrl+c does not work... The only way to terminate it (that I know of) is to end the ssh session. Now, I am new to python so both of these are probably just stupid mistakes so hopefully someone can help. Thanks!</p>

1,682,524 | 1,682,525 | Does it make any sense to develop for iPhone OS 3.0 instead of 3.2? | <p>When it comes to backwards-compatibility, I want to stick to iPhone OS 3.0 so also some of the poor iPod Touch users who aren't rich enough for iPhones use my apps. But iPhone OS 3.2 has some pretty cool features that would be nice to have. </p>
<p>Problematic thing: Since it's just a minor upgrade, I can imagine most iPod Touch users who decided to upgrade to 3.0 probably never upgraded to 3.2. I'm not sure if Apple actually asked them to pay like 10 bucks for going from 3.0 to 3.2. However, if Apple did ask them for money, I'm sure like 90% of all iPod Touch users didn't upgrade. </p>
<p>So the big question is: IF you decide to go with iPhone OS 3.0, is it a stupid idea to stick to 3.2 just because of a few more features? Will this effectively kill half of your iPod Touch userbase?</p>

<p>Here's the database method:</p>
<pre><code>public class Database {
// other methods....
public long addToDatabase( ContentValues values ) {
// I'm getting a NullPointerException right here, trying to retrieve
// a value from this ContentValues object
int weekOfYear = values.getAsInteger( WEEK_OF_YEAR );

// And, if I take the above out, right here
values.put( PARENT_ID, pId );
mDb.insert( table_name, null, values );
}
}

2,777,610 | 2,777,611 | Always launch activity X after resume from background and new launch - Android | <p>I need to implement the following:</p>
<p>When the app starts, activity A is shown (a login screen) that goes to activity B if login credentails are correct.</p>
<p>Activity B is a dasbhoard, that can start several other activities C,D .. (and thus remains active, the user should be able to go back to B if he/she is at C or D).</p>
<p>Now when the user presses the home button, and goes back to the app (ie. by pressing the home button for a long time), the app should show activity A again. It should not resume the activity (B,C,D) it was currently on.</p>
<p>In other words, the app should 'close' when it goes to the background (by launching another app or pressing the home button). However, this seems not so trivial in Android.</p>
<p>I have tried several strategies:</p>
<ul>
<li>use launchmode = singletask for activity A (app can still be resumed when long pressing home)</li>
<li>track the activity stack to see if app is going to the background on onPause (detection does not work flawlessly) and if resumed from background clear activity stack and start activity A again</li>
<li>use clearstack on Activity A and finishTaskOnTaskLaunch on all other activities </li>
<li>use nohistory (no going back to activity B)</li>
<li>use launchmode = singleinstance (actually dont want to go there)</li>
</ul>
<p>All seem to have their edge cases in which it doesnt work (ie. activity B is still resumed in some cases, activity B is closed when going back from activity C or D)</p>
<p>Any ideas? Am I perhaps overlooking something?</p>

<p>fprintf(stderr, "DEBUG: %s\n", "Hello"); </p>
<p>Now this call works fine if i use it from any function in any file in my other project (that uses the library) but if i put it anywhere in my library with the logging class it simply wont print anything.<br>
I can see it runs the function correctly (using a simple exit(0); to test). </p>

2,837,942 | 2,837,943 | Don't fire onfocus when selecting text? | <p>I'm writing a JavaScript chatting application, but I'm running into a minor problem.</p>
<p>Here is the HTML structure:</p>
<pre><code><div id="chat">
<div id="messages"></div>
<textarea></textarea>
</div>
</code></pre>
<p>When the user clicks/focuses on the chat box, I want the textbox to be automatically focused. I have this <code>onfocus</code> handler on the chat box:</p>
<pre><code>chat.onfocus = function () {
textarea.focus();
}
</code></pre>
<p>This works, but the problem is that in Firefox, this makes it impossible to select text in the messages <code>div</code>, since when you try to click on it, the focus shifts to the <code>textarea</code>. How can I avoid this problem?</p>
<p>(Semi-related issues: In Chrome, <code>textarea.focus()</code> doesn't seem to shift the keyboard focus to the <code>textarea</code>; it only highlights the box. IE8 does not seem to respond to the <code>onfocus</code> at all when clicking, even if it <code>tabindex</code> is set. Any idea why?)</p>

1,153,524 | 1,153,525 | Dictionary values by reference | <p>In our application we have some strings coming from translation that can contain variables. For example in <code>Can i have a {beverage}?</code> the <code>{beverage}</code> part should be replaced with a variable.
My current implementation works by having a Dictionary of the name and value of all variables, and just replacing the correct string. However i'd like to register the variables by reference, so that if the value is ever changed the resulting string is changed as well. Usually passing a parameter with the <code>ref</code> keyword would do the trick, but i'm unsure on how to store those in a Dictionary. </p>
<p>TranslationParser:</p>
<pre><code>static class TranslationParser
{
private const string regex = "{([a-z]+)}";
private static Dictionary<string, object> variables = new Dictionary<string,object>();
public static void RegisterVariable(string name, object value)
{
if (variables.ContainsKey(name))
variables[name] = value;
else
variables.Add(name, value);
}
public static string ParseText(string text)
{
return Regex.Replace(text, regex, match =>
{
string varName = match.Groups[1].Value;
if (variables.ContainsKey(varName))
return variables[varName].ToString();
else
return match.Value;
});
}
}
</code></pre>
<p>main.cs</p>
<pre><code> string bev = "cola";
TranslationParser.RegisterVariable("beverage", bev);
//Expected: "Can i have a cola?"
Console.WriteLine(TranslationParser.ParseText("Can i have a {beverage}?"));
bev = "fanta";
//Expected: "Can i have a fanta?"
Console.WriteLine(TranslationParser.ParseText("Can i have a {beverage}?"));
</code></pre>
<p>Is this possible at all, or am i just approaching the problem incorrectly? I fear that the only solution would involve unsafe code (pointers).</p>
<p>So in short, i'd like to store a variable in a Dictionary, change the original variable and get the changed value from the Dictionary. Like you would do with the <code>ref</code> keyword. </p>
