How to get rid of "Untitled - MyApp" in MFC

To get rid of the "Untitled" alone, you can override the CDocument virtual function "SetTitle" as shown below.

   void CMyDoc::SetTitle(LPCTSTR lpszTitle) 
     {
       CDocument::SetTitle("MyTitle");
     }

This will produce a main window title of the type "MyTitle - MyApp". But perhaps all you want is "MyApp".

You can set the main window title from just about anywhere in your application using the statement shown below.

   (AfxGetMainWnd( ))->SetWindowText("MyApp");

The problem with this approach is that MFC in its infinite wisdom will reset your window title to the "Document - App" default as soon as a document object is constructed. If you care to change MFC's default behavior ( not advised ) look up WINMDI.CPP; it's the culprit.

Finally, you can overwrite the CFrameWnd virtual function "OnUpdateFrameTitle" in your apps CMainFrame class. Bud Milwood, a friend of mine, pointed out the function's very existence when I was loosing my sanity browsing the MFC online help. Don't try to look up "OnUpdateFrameTitle" in the Microsoft Developer Studio online help. It's not there. So use it merrily, but use it wisely, subsequent versions of MFC may not support it. The following code snippet shows how...

   void CMainFrame::OnUpdateFrameTitle(BOOL Nada) 
    {
      // get app name from string table resource
      //----------------------------------------
      CString csAppName;
      csAppName.Format(AFX_IDS_APP_TITLE); 

      // Set caption of main frame window
      //---------------------------------
      SetWindowText(csAppName);
    }

Another and probably safer method has been brought to my attention by Stephen Michael Schimpf at CyberSky.Simplenet.Com. You can modify the window style in 'PreCreateWindow' as follows:

 
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
    cs.style &= ~(LONG) FWS_ADDTOTITLE;
   
    return CFrameWnd::PreCreateWindow(cs);
}
