Re: MFC and User Defined objects

Thanks for help,

I got it to work. Everything seems to be fine. I am able to post
messages to main gui thread produced inside user defined object.
However, I am a unsure of how and where is the appropriate place to
retrieve the main gui window handle. Is it done inside the adapter
that converts C win32 api to C++ and vice versa? Or do I retrieve
handle before thread creation?

Currently, I am retreiving main gui window handle just before running
code for thread creation. I tried retrieving handle using the code
below without success.

               CString a;
CDummyDlg i;
HWND h = i.m_hWnd;
a.Format("i.m_hWnd %d", h);
AfxMessageBox(a);

This code fails. I don't understand why. It always gets 0 as
handle. What am I doing wrong? The code listed below works . I get
a valid window handle. But why can't I retrieve the handle using
above method? To me above code seems more logical.

               HWND mywin;
mywin = ::FindWindow(0,"Dummy");
a.Format("Window Handle %d", mywin);
AfxMessageBox(a);

The other thing is I decalared mywin as a global variable. Because
otherwise, I get failure inside my c->c++ adapter code. It reports
that mywin is undeclared.

// Adapter code
UINT CDummyDlg::tMain(LPVOID p)
{

CDummyDlg * self = (CDummyDlg *)p;
self->tMain(mywin); <<< Here it says undeclared variable if I don't
make mywin global variable.
return 0;
}

If you guys eliminate some mysteries on how to appropriately construct
my code, that will help me become a better coder. Thanks.
