I'm wasn't sure if I should have put this in C# or the VB.NET--but anyway, I decided either way would work.

I have this class--not my own code--but I want to make use of it. And since I don't have C# and also don't know it (would learn it if I had it) I need to convert it. Would anyone please help me convert it? I know some of it will convert without really even needing too much knowledge of C# but some of it I'm not sure what the equivalents are.


Help would be greatly appreciated.


Thanks
(I'm sure this is all I need, I actually have the whole project but can open it- But if more information is needed I can provide it--just ask.)
