SUMMARY
=======
To create an initially minimized or maximized document in an MDI application,
derive a class from CMDIChildWnd and override ActivateFrame(). In the
ActivateFrame() member function, call the ActivateFrame() function in the base
class, and pass SW_SHOWMINIMIZED or SW_SHOWMAXIMIZED as the parameter.
MORE INFORMATION
================
If you're using a version of Visual C++ earlier than 4.0, it is necessary to
derive a class from CMDIChildWnd and substitute the new class name in the
CMultiDocTemplate used in your CWinApp-derived InitInstance() function. To do
so, use ClassWizard to add a class called CChildFrame derived from CMDIChildWnd.
Include the header file in your application's .cpp file. Then change the line
indicated below in your InitInstance() function:
CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(
IDR_MDIAPPTYPE,
RUNTIME_CLASS(CMDIAppDoc),
RUNTIME_CLASS(CChildFrame), // change CMDIChildWnd to CChildFrame
RUNTIME_CLASS(CMDIAppView));
AddDocTemplate(pDocTemplate);
In Visual C++ 4.0, deriving a class from CMDIChildWnd is not required because one
is already provided for you.
In the CChildFrame class, override the ActivateFrame() member function as
follows:
void CChildFrame::ActivateFrame(int nCmdShow)
{
if (nCmdShow == -1)
nCmdShow = SW_SHOWMAXIMIZED;
CMDIChildWnd::ActivateFrame(nCmdShow);
}
