I just built a simple database using CFormView. When I was completing the wizard I clicked for the form to start up minimized. After completing my project, I found myself wishing I had chosen to have it start maximized. How can I change this after I've finished? I'm new at this so take pity if it's just a simple change I need to make. Thanks!

Look in the InitInstance() method.

Thank you, I checked InitInstance() and even InitApplication() and can't find anything that would possibly correct this. Any other thoughts? I really appreciate your guidence.

Thanks

I created an app that minimizes when it opens and this is what I found.

BOOL CMyApp::InitInstance()
{
...
...
...
	// Dispatch commands specified on the command line
	if (!ProcessShellCommand(cmdInfo))
		return FALSE;

	// The one and only window has been initialized, so show and update it.
	m_pMainWnd->ShowWindow(SW_SHOWMINIMIZED);
        m_pMainWnd->UpdateWindow();

	return TRUE;
}

Change or add m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED); to the above code.

Did you overlook the m_pMainWnd->ShowWindow(SW_SHOWMINIMIZED) statement in the InitInstance() method?

Below is my initInstance Function. There is no :"m_pMainWnd->ShowWindow(SW_SHOWMINIMIZED)". Is there another place it could possibly be? Thank you for your patience!

Was this created with Visual Studio 6? Have you looked at the project's frame-related classes to see if they are adjusting the window's size? Since it is an MDI application, have you looked at the CChildFrame::ActivateFrame() method?

Yes, I did check them. this program is being compiled in VS.Net. Is .Net different enough from 6.0 that there would be something else to consider?

Since I do not use .NET, I cannot say.

You might want to create three projects, A and B and C, with one being initially minimized, one being initially maximized, and one being the default settings. Then compare the files to see where the difference is.

Anyone can explain me what is the concept of data class. How it is different then the normal class.
