- Dialogs again
- Posted by Allan Bruce on July 17th, 2003
In my dialog box, I am redrawing a rectangel based on the position of
sliders. I use this code to see if the sliders have moved
case WM_VSCROLL :
GetWindowRect(hDlg, &rect);
InvalidateRect(hDlg, &rect, FALSE);
return TRUE;
This works fine unless the user moves the dialog box then the redrawing
doesnt work. How can I get around this (without making the dialog box
non-movable).
Also, is there a WM_ message I can send to change the title of the dialog
box?
Thanks
Allan

You could memorize WM_SIZE information.. but you should
use GetClientRect()... or just invalidate the whole window
by specifying NULL instead of &rect.
There is... but mostly one uses the API SetWindowText().

This doesn't make sense to me. GetWindowRect returns a rectangle in screen
coordinates and InvalidateRect expects a rectangle in client coordinates so
unless the dialog box is in the top left of the screen it's not going to
work. Use GetClientRect instead.
WM_SETTEXT or call SetWindowText()
