Just another point, if you have a toolbar down the side of the screen,
GetSystemMetrics doesn't take it into account, so you can use

    RECT screen;

    BOOL rv = SystemParametersInfo ( SPI_GETWORKAREA, 0, & screen, 0 );

    cs.cx = screen.right;
    cs.cy = screen.bottom;
    cs.y = screen.top;
    cs.x = screen.left;

Hi,

How simple is it to center an SPI application when it starts up in a
non-maximized window?

J

Here is another cool trick to center the mainframe at 90% of the screen
size. The code is added in the PreCreateWindow function.

--- snip ---
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CMDIFrameWnd::PreCreateWindow(cs) )
return FALSE;

// add this ------------------------------
int xSize = ::GetSystemMetrics(SM_CXSCREEN);
int ySize = ::GetSystemMetrics(SM_CYSCREEN);
cs.cx = xSize * 9 / 10;
cs.cy = ySize * 9 / 10;
cs.x = (xSize - cs.cx) / 2;
cs.y = (ySize - cs.cy) / 2;
// ---------------------------------------

return CMDIFrameWnd::PreCreateWindow(cs);
}

--- snip ---
