4 threads for one question. You shouldn't multiply posts like that, there's many people who don't like.

please somebody ban this joker. this thread duplication stuff is ridiculous. most of the tutorials are included in C# or VB.NET in the SDK under the examples.net\Examples_CSharp folder. you didn't even need web access to find the answer to your question.

i'm sorry

thank you very much for every thing.
