<p>I've created several Javascript classes with fields and methods. When I read an object's field that doesn't exist (due to a typo on my part), the Javascript runtime doesn't throw an error or exception. Apparently such read fields are 'undefined'. For example:</p>
<pre><code>var foo = new Foo();
foo.bar = 1;
var baz = foo.Bar; // baz is now undefined
</code></pre>
<p>I know that I can check for equality against 'undefined' as mentioned in "<a href="http://stackoverflow.com/questions/27509/detecting-an-undefined-object-property-in-javascript">Detecting an undefined object property in JavaScript</a>", but that seems tedious since I read from object fields often in my code.</p>

<p>And why is an exception thrown when I read an undefined variable (as opposed to undefined object property)?</p>

<p>Due to some design constraints that are beyond my control, this needs to be converted. Converting to a string isn't a problem.

<p>He has already done quite a bit of work and the site is almost there but I need someone who is better to take it the rest of way. The site has been done in asp.net and I am wondering how hard it would be for a more experienced programmer to take over and finish the work he has already done? </p>
<p>In general, is it hard for an asp.net programmer to come in towards the end of a project and fix what needs to be fixed?</p>
<p>There is five different pages on the site with two overlays for a signup and sign in. (Five pages with many different versions) There is a database and client-side scripting. AJAX was also used. It's a site somewhat similar to SO only not quite as complex and about something completly different. I would say think of something that falls somewhere between Stackoverflow and Craig's List. Thats all I can say now as I don't know the technical words.</p>

<p>I am creating a card game, and I want the player to be able to see his cards like how pople normally hold their cards in one hand (rainbow style). So currently, I have each card being an imageview and they are just best each other. How can I rotate each imageview by a certain angle? I don't want to use rotate animation as it does not change the x/y positions of the image after rotation which prevent from getting a touch on the corner of the card

I would cover basic c++ first week, and start the project second week.</p>
<p>What I need is a project that is doable (for them) in 2 weeks. It is interesting. Somehow I want it to be interactive (something that's cool, something that we get to use a lot or something like that)?</p>

5,646,716 | 5,646,717 | Simple? Increase Field/Box Size | <p>We have a custom CMS on a football website. Within the CMS admin panel is a squad biography section, as shown here:</p>
<p><img src="http://i.stack.imgur.com/VTjBJ.jpg" alt="app.php"></p>
<p>On the above screenshot you will see the ‘Biography’ section highlighted. The code for this section within /app.php is;</p>
<pre><code> <ul class="tr">
<li class="td1">Biography</li>
<li class="td2"><input type="text" name="biography" value="<?=$row['biography']; ?>" /></li>
</ul>
</code></pre>
<p>I’m trying to make the Biography box bigger as this field will require several paragraphs. Currently, it’s just one character limited row.</p>
<p>I’m also hoping to replicate making the box bigger on the actual outcome too. Screenshot of which is here: <img src="http://i.stack.imgur.com/C0bYD.jpg" alt="index.php"></p>

<pre><code><ul class="tr">

</ul>
</code></pre>
<p>Any help as to how I can make the input and output boxes bigger (to accommodate paragraphs rather than one single line) would be massively appreciated.</p>

2,911,384 | 2,911,385 | Disposable Using Pattern | <pre><code> using (FileStream fileStream = new FileStream(path))
{
// do something
}
</code></pre>
<p>Now I know the using pattern is an implementation of IDisposable, namely that a Try/Catch/Finally is set up and Dispose is called on the object. My question is how the Close method is handled.</p>
<p><a href="http://msdn.microsoft.com/en-us/library/yh598w02.aspx" rel="nofollow">MSDN</a> says that it is not called, but I have read otherwise.</p>
<p>I know that the FileStream inherrits from Stream which is explained <a href="http://msdn.microsoft.com/en-us/library/ms227422.aspx" rel="nofollow">here</a>. Now that says not to override Close() because it is called by Dispose().</p>
<p>So do some classes just call Close() in their Dispose() methods or does the using call Close()?</p>

<p>Edit: i am not adding any variables to the array, only another key value pair. The problem is that the array is part of a file with more arrays in it about which I won't always be aware. I can achieve this if there was only one array in the file, but want to know if it is possible to do this with multiple arrays.</p>

1,718,326 | 1,718,327 | Using Resources in Exceptions | <p>I have an app that uses custom Exceptions, such as this:</p>

iMessage = **//Get the localized string R.string.error_201??**

}
@Override
public int getCode() {
return iCode;
}
}
</code></pre>
<p>Obviously, I want lo localize the error message. I have possible solutions but non of them satisfy me.</p>
<p>1) Pass "Context" to the constructor, and do ctx.getString(R.string.error_201)
--> Fail, as this Exceptions are sometimes thrown from MODEL classes, so they don't have a Context</p>
<p>2) Pass "Context" when retriveing the message in getMessage() function,
--> Fail, It's necesary to override the super method, to work as all other Exceptions.</p>
<p>Solution I have now: All activities in my app have this onCreate:</p>
<pre><code>public void onCreate(...){
Utils.RESOURCES = getResources();
...
}
</code></pre>
<p>Very dirty code... I don't like the solution. My question is then,: is there a way to access the resources without the Context? And most important, How would an application such as mine solve this problem?</p>

<p>I'm moving an old website from classic asp to asp.net, and one of the things that used to happen on the site was individual pages being changed in isolation. The site is only on a single server, and has a lot of files so doing a re-publish would take the whole site down for a while. I'd like to avoid that, or at least make that time as short as possible.</p>
<p>Each page does have a code behind file, and there's some stuff used by each page in App_Code (just in case that changes the answer).</p>

492,008 | 492,009 | PYTHON - Comparing two different files; if a line containing an ID already exists then update else append the line | <p>I have a master file which is the one which will constantly be updated and a file which is created every minute. I want to be able to compare the new file which is created every minute to the already existing master file. So far I've got:</p>
<pre><code>with open("jobs") as a:
new = a.readlines()
count=0
for item in new:
new[count]=new[count].split(",")
count+=1
</code></pre>
<p>This will allow me to compare the first index([0] of each line in my master file. Now at this point I start to confuse myself. I'm guessing it would be something along the lines of:</p>
<pre><code>counter=0
for item in new:
if new[counter][0] not in master:
end = open("end","a")
end.write(str(new[counter]) + "\n")
counter+=1
end.close()
else:
REPLACE LINES THAT ALREADY EXIST IN MASTER FILE WITH NEW LINE
</code></pre>
<p>The IDs won't necessarily be in the same order every time the new file comes in and the new file may contains more entries than the master file at some point.</p>
<p>If I haven't made sense or missed some information out then please let me know and I'll try and clarify. Thanks.</p>
