Hi SunilKumar111,

Could you please cover your VB6.0 application in more details? Is it a control DLL and you want to use it in your C# application or it is a single application?

Thanks!

Hi, Feng Chen !

Both C# and VB6.0 applications are standalone windows applicatios(no DLL). Both will be run separately on the same machine. I need to pass some string data to vb6.0 application.

Hi SunilKumar111,

I suggest that you can use WM_COPYDATA to send data between the different processes. To achieve this, you can use SendMessage function in C# through P/Invoke. And there are several references on this issue:

· Inter process communication using registered messages from Visual Basic

· Use WM_COPYDATA to send data to/from C++ and C# Windows processes

· Inter-Process Communication using WM_COPYDATA

Hope this helps!

Thanks!
