Is there a getclientrect() member function? Just a guess.... -Ken Mazaika

GetClientRect returns just the client area. GetWindowRect returns the area of the entire CWnd object. See API docs for CWnd. Best Regards. -Matt ------------------------------------------ The 3 great virtues of a programmer: Laziness, Impatience, and Hubris. --Larry Wall

#define RectWidth(lprc) ((lprc)->right-(lprc)->left)
#define RectHeight(lprc) ((lprc)->bottom-(lprc)->top)

RECT rc;
int width,height;
GetWindowRect(hwndRichEdit,&rc);
width=RectWidth(&rc);
height=RectHeight(&rc);

I'm curious as to why you would do it that way. This is not a criticism, just a curiosity. Why couldn't you just use CRect instead? Also, why are you using the globally scoped GetWindowRect rather than the CWnd GetWindowRect? Is there a benefit to doing it that way? Here's the way I would do it:

int width = 0, height = 0;
CRect rect;
GetWindowRect( rect ); // Single parameter CWnd::GetWindowRect
width = rect.Width();
height = rect.Height();

Thanks. -Matt ------------------------------------------ The 3 great virtues of a programmer: Laziness, Impatience, and Hubris. --Larry Wall

Maybe he isn't using MFC/WTL or doesn't want to force that dependency on others. Tim Smith "Programmers are always surrounded by complexity; we can not avoid it...
