SharpDevelop Community

So there I was, playing with the Slider Puzzle sample that comes with the .NET Framework 2.0 SDK (this sample is for the Compact Framework), which is a C# sample, and it runs fine, Though I did find a bug in the MS code, even though I don't know C# (BoardForm.CS line 107, should be @"/" instead of @"\" apparently).

Anyhow, I was playing around with the "Convert buffer C# to VB.NET". The Tile.cs and Puzzle.cs files converted fine, then I tried to convert the Boardform.cs file. This is the error that came up. As the exception window indicated, I figured you guys might like to know about it!

Can you please post the code you tried to convert?

Sure thing. I didn't bother originally, figuring everyone probably had the SDK stuff on the machines already.

This is a ZIP of the project directory. Let me know if there's anything else I can do to help... My background is VB-heavy, but I'm picking up .NET and jumping ship from MS to SD at the same time - I do enjoy a good challenge :-)


I can't see how to attach a file here, so I'll just link it:

CS.zip

EDIT: I don't know if it helps, but the online code converter in the blog (here) crashes also.

This bug has been fixed in a recent version. Thanks for your report.

Thanks for the bug report? More like thank YOU for #Develop :-)
Just trying to do my little part!
