Help: Starting MFC app with its window hidden

Hi!

I'm trying to have my MFC dialog-based application start with its main
window hidden, but I can't seem to figure out how to do it. Can anyone give
me a few pointers?

Thanks!

Help: Starting MFC app with its window hidden

Steps to hide a dialog based app..

example..consider your app name is Test1....
CTest1App Test1.cpp and Test1.h
CTest1Dlg Test1Dlg.cpp and Test1Dlg.h

1. "uncheck" the Dialog properties visible checkbox
2. add #include "test1dlg.h" in the Test1.h
3. add CTest1Dlg *m_pDlg; as a member variable to CTest1App class.
4. delete the CTest1Dlg dlg line in InitInstance of Test1App.cpp
5. your InitInstance method should look like this....and add the
ExitInstance method also

////////////////////////////////////////////////////////////////////////////
/
// CTest1App initialization
BOOL CTest1App::InitInstance()
{
AfxEnableControlContainer();

#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif

m_pDlg = new CTest1Dlg;

m_pMainWnd = m_pDlg;

m_pDlg->Create(IDD_TEST1_DIALOG);
m_pDlg->ShowWindow (SW_HIDE);

return TRUE;

Quote:

}

int CTest1App::ExitInstance()
{
delete m_pDlg;
return CWinApp::ExitInstance();

}

It should work...

PostMessage a user-defined message and respond to it by hiding the window.

Note: if you want to eliminate the flash, in OnInitDialog, position the window off-screen,
then after you hide it, reposition it to be on-screen so when it becomes visible it is
actually seeable.

Other than the fact that m_pMainWnd is not set, which has other {*filter*} implications...
