11.3. Creating an app that is initially maximaized.

11.3. How can I create an application that is initially maximized?

For new applications, this can be done with AppWizard during Step 4. During Step 4, choose Advanced..., and then select the Main Frame tab. Check the Maximized option.

For an MDI application, in the CWinApp::InitInstance() function, set CWinApp::m_nCmdShow to SW_SHOWMAXIMIZED before calling pMainFrame->ShowWindow(m_nCmdShow). In an application generated by AppWizard, the code is as follows:

// create main MDI Frame window
CMainFrame* pMainFrame = new CMainFrame;
if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
m_nCmdShow = SW_SHOWMAXIMIZED; // ADD THIS LINE!
pMainFrame->ShowWindow(m_nCmdShow);
pMainFrame->UpdateWindow();
m_pMainWnd = pMainFrame;

In an SDI application, in the CWinApp::InitInstance() function, set CWinApp::m_nCmdShow to SW_SHOWMAXIMIZED before calling OnFileNew().For example, in an application generated by AppWizard, the code is as follows:

m_nCmdShow = SW_SHOWMAXIMIZED; // // create a new (empty) document OnFileNew();
