I'm OnPaint () open a BMP file and put it on the Static controls,
In another message response response function is open the file, and created a modal dialog box,
As soon as the situation now is to create a modal dialog box OnPaint () in the MessageBox () will play out
I suspect that in the process of message response can also respond to other message, don't message response function is to create a thread to handle alone?
Confused now, wish you a great god can help
