Subject: [DUG]: Freeze updates
Can someone tell me how to stop a window display from being
refreshed/updated?
It is being used as a video capture window, and as I am writing the data to
a bitmap, it is being changed eg
//freeze panel updates here then..
BitBlt(BMP[framecount].hdc, 0, 0, panel1.Width, Panel1.Height, hdc, 0, 0,
SRCCOPY);
//now unfreeze updates
//where hdc is hdc:=GetDC(hwndc);//panel1.handle
All I see is refresh, invalidate and so on.
I have tried:
InvalidateRect( hwndc, NIL, FALSE ) ;
Tks,
Al+
