Can anybody help me, I don't know how to run a code by using Visual Studio 2011 on window 7 64 bit.

PS: This forum is talking about Visio that a part of MS office, not Visual Studio. And Visual Studio has no 2011, I think you might use Visual Studio 2010.

If you have any further question about Visual Studio, please post the question to MSDN forum:
