CWnd::Create -> program terminates immediately after window creation

[hanhao]

hi, i am new in MFC so i would need detail explaination and preferbly some codes

here is the application initialization

/////////////////////////////////////////////////////////////////////////////
CAsevApp theApp;
// CAsevApp initialization

BOOL CAsevApp::InitInstance()
{
	// Standard initialization
	// If you are not using these features and wish to reduce the size
	//  of your final executable, you should remove from the following
	//  the specific initialization routines you do not need.
	RECT rec;
	rec.bottom=100;
	rec.left = 100;
	rec.right = 100;
	rec.top = 100;

	main_window *m_pMainWnd = new main_window;
	m_pMainWnd->Create(
		"myWindowClass",
		"title",
		WS_OVERLAPPEDWINDOW,
		rec,  CWnd::GetDesktopWindow(),0,0);
return TRUE;

main_window is a derived class from CWnd, no extra stuff has been added

here i am trying to create a simple window with the "create" command
or more specifically, CWnd::Create command
what happens is that the program terminates immediately

i was expecting an empty movable/resizable window with the titlebar "title" to appear and stay there

is there something i did wrong?

please assist

try a domodal or other creation method, or somehow trap the on-close of the window before you return (which ends the program!)
