Setting the Window size

hi

in a simple SDI-Application created by the MFC-wizard, how do I set the windowsize upon the initialization of the program?
I´ve tried inserting the following commands in the CView::PreCreateWindow function:

CWnd* mywin = AfxGetMainWnd(); // Points to my only application window ( I think )
mywin->SetWindowPos(mywin, 300,300,200,100,SWP_SHOWWINDOW);

It runs ok but does not do anything at all. Where should this statement be located or what would be the correct command?

thx

You just set the CREATESTRUCT to the disered width, hieght, and starting position :
Look up CREATESTRUCT in the msdn libraray
example:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CMDIFrameWnd::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cx = ?;
cs.cy = ?;
cs.x = ?;
cs.y = ?;

return TRUE;
}

You should determine the size you want before call
CWnd::PreCreateWindow

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cx = ?;
cs.cy = ?;
cs.x = ?;
cs.y = ?;

return CFrameWnd::PreCreateWindow(cs);
}

Good luck.
