Weekend Project: Video Poker in C# and Silverlight

I’m working on building an electronic piggy bank style box like this one I’ve seen that will count my spare change, and I wondered if I could make it more interesting. I thought back to coin-operated arcade machines and thought that I could make a pretty cool video poker software that would read my piggy bank and let me play poker with my change as well. I decided to learn a new language to do it: Microsoft’s C# (sharp).

A few good friends of mine use C# in their jobs, and its an interesting choice because it’s a .NET language and the same code can be used on the Windows desktop and online using Microsoft Silverlight.

I ported some old Python code I had over to C# to learn about what makes it different, and after a bit of searching through the Microsoft Developer Network (MSDN) I found out the correct ways to do some things, and after some more tinkering and learning WPF, the Windows Presentation Format, I had my application.

Now, I don’t want to break any gambling laws so all the “credits” earned are 100% virtual, and have no cash value. In the future I can wire this up to the coin acceptor I’m building to accept more credits into the machine, but once they’re there, they stay there. I did make a rudimentary user account system that saves ones balance in-between sessions, so I can reboot my computer and I can still play later.

I still need to learn how to cache the card images somewhere, because every time I draw the cards the images are pulled from my server again and again.

To the web!

As I said, I’ve heard that Silverlight makes it easy to cross-compile applications for the web. It’s true for the most part, but there are some discrepancies. First, some controls such as the Label that work in WPF don’t work in Silverlight. Also, any Class Library DLL files that you’ve compiled for the desktop won’t be able to be added to Silverlight, so make sure if you’re compiling for both that you save your .cs files!

I make a few changes to my application since that screenshot was taken, and have made a web-playable version. This lacks user accounts, and you’re awarded 100 credits every time you visit the page! If you go below 0 credits, I don’t know what happens, but I think you just go into the negatives. It’s a prototype, and it’s controlled entirely via the keyboard for now. Make sure to click the blue background before using the keyboard to make sure the program has focus! I might improve it later, but my focus is on the desktop implementation for now.

I’ll be on Spring Break for the next week, but I’ll update once I get back!
