Thanks Chris Tacke.

I have looked into the website.
It gives me lots of help;
now My question is:
I create a Window Application by Evc4.0 (indenpend exe file)
and another window Application by C#(indenpend exe file),
I want to communicate message between them.

On Evc Application4.0, I use findwindow to get the Handle of C#Window
Application.
and use Sendmessage, It does not work.
I can not transfer the HWND of C# application MessageWindow to evc4.0
Application.

Is it Possiable about my issue?

thanks

Look at P/Invoking SendMessage() or PostMessage() to send a message to all
top-level windows in the system (or you may be able to use FindWindow() to
locate the right window of your eVC program, to minimize your broadcasting
of messages). Going in the other direction, you could use, again, a
broadcast and use something like ApplicationEx and an IMessageFilter
(defined by OpenNETCF's SDF), to catch the return message from the eVC
program.

Thanks Paul G.

Now I get my application works, and It works pretty good.
I have another question :

When I use SendMessage to C# Windows Application.I use MessageWindow to
Listen the message.
I want to send a string to C# Window Application
So I write :
LPTSTR szContent = _T("want to send to c#");
SendMessage(TO_CSHARP_MESSAGE,(WPARAM)szContent,0);

however, C# side, How can I change the WPARAM parameter to string?

thanks
