FIX: Advanced Options for SDI Application in Appwizard

RESOLUTION

MFC stores the value passed through the nCmdShow argument to WinMain in CWinApp::m_nCmdShow. This variable can be modified to get the behavior you want. To have an SDI application initially maximized or minimized, set this variable to the appropriate value. Set m_nCmdShow to SW_SHOWMAXIMIZED to maximize or SW_SHOWMINIMIZED to minimize the main frame window initially. This variable has to be modified in the InitInstance() function of the CWinApp-derived class before the main window is made visible.

In the Visual C++ 4.0 or 4.1 AppWizard-generated application, set this variable before this line:

   if (!ProcessShellCommand(cmdInfo))
      return FALSE;
				

If the application was generated with an earlier version of Visual C++, set m_nCmdShow to the appropriate value before this line:

   OnFileNew();
				

In the Visual C++ 4.2 AppWizard-generated application do the following:

    if  (!ProcessShellCommand(cmdInfo))
        return FALSE;

    m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);
				

   // Visual C++ 4.0, 4.1, or 4.2 AppWizard-generated SDI application
   BOOL CMyApp::InitInstance()
   {
   ...
      ParseCommandLine(cmdInfo);

           // Add the following line to initially maximize the Application.
           m_nCmdShow = SW_SHOWMAXIMIZED;

      // Dispatch commands specified on the command line.
      if (!ProcessShellCommand(cmdInfo))
         return FALSE;

      return TRUE;
   }

   // Visual C++ 2.0 AppWizard-generated SDI application.
   BOOL CMyApp::InitInstance()
   {
   ...
      AddDocTemplate(pDocTemplate);

           // Add the following line to initially maximize the Application.
           m_nCmdShow = SW_SHOWMAXIMIZED;

      // Create a new (empty) document
      OnFileNew();
   ...
   }
