3,023,178 | 3,023,179 | Custom container control | <p>I'm trying to create a CollapsiblePanel control, which is essentially just a panel which has a header which can be used to expand / collapse the body.

<pre><code><cc:CollapsiblePanel runat="server" Header="This is a collapsible panel">
<asp:Label runat="server" Text="This is the contents of the panel" />

Most times the new icon was distributed to simulator or device with the very next build, sometimes I had to delete and add th icon.png in Xcode (images), but it worked.
Then, the other day I added the UIPrerenderedIcon element to the info.plist to eliminate the icon's shine (it worked) and since I did, I've problems with bringing new icons to the device:</p>
<ul>
<li>Simulator shows new icon when in debugging mode</li>
<li>Simulator doesn't present new icon in release mode (only when debugging was used before)</li>
<li>Never new icons on any iPhone or iPod</li>
<li>Whenever icon distribution fails, a white square or (even stranger to me) an old icon (corresponding .png is completly eliminated from the file system) is shown</li>

struct card card = PickACard(deck);
PrintHand(TextCard(card));

<p>The parameter for 'PrintHand' causes compilation errors no matter what I do. Here are both the functions.</p>

I would prefer it to be platform independent. I intend to use Python, which I have some experience with. For user data storage, after previous experience with MySQL, a flat database design would be preferable but not essential. Okay, now the questions:</p>
<p>Is it worth starting with Python 3, or is it still too poorly supported with ports of modules from previous versions?</p>
<p>Are there any great advantages in using Python 3 for my particular project? Would I be better off looking at using other languages instead, such as Erlang?</p>
<p>Is there any great advantage in using a relational database within a game server?</p>
<p>Are there any open source game servers' source code out there that are worthy of study before starting?</p>

<pre><code>[Thor, 50, Marvel]
[Thor, 51, Marvel]
[Thor, 52, Marvel]
...
eventually, I 'd like to include entries for story arc, writer, artist, etc.

<pre><code>option = 0
comicdb = []
while option != 3:
print "--------------------------"
print "1. Add a New Comic Book"
print "2. Print the Database"
print "3. Quit"
option = int(raw_input("Pick an Option: "))
if option == 1:
title = raw_input("Comic Book Title: ")
issue = int(raw_input("Issue Number: "))
publisher = raw_input("Publisher: ")
comicdb.append(title)
comicdb.append(issue)
comicdb.append(publisher)
print comicdb

<p>After running the code a couple times, the list looks like:</p>
<pre><code>['Thor', 50, 'Marvel', 'Thor', 51, 'Marvel', 'Thor', 52, 'Marvel']

<li>i should use a dictionary or tuple instead of a list</li>
