Hi,

The problem may be in getting the DC. Check if you are getting the DC properly.

If yes, Try drawing a line or something at the centre of the dialog so that the lines

are not hidden behind the menu.


OR check the background color, Brush color and Pen color.


I have used dlg based appln and I was able to draw lines.


If you need further help, post the code


All the Best
