Thread: Custom messages cause failure in Release.

I'm making a network chat program using MFC in VC++ 6. I derived a class from CAsyncSocket. At the top of this class's header file I added:

#define DSOCK_RECEIVE WM_APP
#define DSOCK_CONNECTED WM_APP+1

It has a pointer (HWND* m_hWndParent) to the HWND of the dialog class it's a member of. In some of it's functions it calls this:

SendMessage(*m_hWndParent, DSOCK_RECEIVE, 0, 0);

In the dialogs message map it has:

ON_MESSAGE(DSOCK_RECEIVE, OnDSockRecieve)

At runtime in the Debug build of this application all goes smooth, at runtime in the Release build it says "Chat has caused an error in MFC42.DLL." I tried commenting out only the part where it sends the mesage and it ran fine. I cannot think of any other way to "get the message across" to my dialog. And I don't know why this fails. Any suggestions? ANSWERS?

Thanks in advance.

I'm still have the same problem.

I've tried using a pointer to the dialog class (CDialog*) and calling it's SendMessage(DSOCK_RECEIVE), but that fails in Release and works in Debug as well.

It seems like passing a message to another class should be relatively easy. I cannot however include my dialog classes header in my socket classes header and call the dialog class functions directly, because I'm trying to make my socket class easily reusable in other applications.
