Thanks. This will not work for the requirement as I need to draw lines between window dialogs.

Hi Olivier Levrey,

Thanks for the response. I am currently using InvalidateRect for erasing the lines. But when I opened the application on top of any other windows/applications like IE, Word etc, the lines drawn on those windows can not be erased because I don't have control to repaint it, so I have to do Ctrl+Tab or min/max as to erase the lines. If use SetROP2 with R2_XORPEN, the lines are getting erased when my app is opened on top any windows. But it inverts the portion of line color which passing the desktop window. Typically both the solutions ( 1) SetROP2 with R2_XORPEN 2) drawing manually with default mode and using InvalidateRect) have issues. Hence looking for some solutions for either of the method. Help!
