why cant i paint on the window on my MFC PRogram.

nothing appears just blank

can anyone help me on this pls

[Ancient Dragon]

Your program should probably call UpdateWindow() to force the WM_PAINT message to be put into the message queue. Have you read MSDN OnPaint description?

[Covinus]

il read it. but i added that updatewindow thing and still nothing

[Covinus]

WM_PAINT is in the message queue. but my draw text is ignored. nothing comes out of my window. maybe there are some steps i missed before drawing a text.

[Covinus]

i got it. hehehe
