Hello everybody, I have a big understanding problem. If I write those 2 lines
InvalidateRect(CRect(0,10,0,10));
GetUpdateRect(testrect);Then "testrect" is empty. Shouldn't it get the values of my InvalidateRect? Big thanks for any help :)
In fact, your rectangle is empty:
CRectconstructor accepts, as parameters, rectangle's {left,top, right, bottom}. See CRect constructor at MSDN. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke
