What is the best way to achieve an overlay drawing which works on all Windows versions (since XP) at the same time appearing in screen-captures. Not to mention, it is very performance heavy to draw constantly.
But this may show a bit of flicker when the text is selected. The last resort is to draw the custom shape on the target window in a timer continuously so the drawing is always above the target, even on text selection. Tracking all possible paint events is not a good way to do this. The problem is that applications may draw without a paint event, like when some text is selected using the cursor, and such drawing may erase a part of the custom drawing. The shape can be drawn on the desktop window instead too. Region window also leaves traces on dragging the application window.Īnother approach is to sub-class the target window and draw the shape on its HDC on the OnPaint() event inside the window procedure hook. However, region windows are generally very slow in rendering complex shapes and also impact the performance of other windows, sometimes to the point of freezing the application.

The crude approach to support all Windows versions then is to use a region window using SetWindowRgn and make the target window its owner.

But the problem is on Windows 7 and XP, layered windows do not appear in a BitBlt done without the CAPTUREBLT flag and the screen-capturing tools may call BitBlt without the flag, thereby skipping our window from the capture. Using a layered window as the child/owned window of the target window is the easiest thing and it works. So far we've tried several ways but each method has its problems: The target window is not made using our code. Also, moving the target window around should not leave traces of the drawing at earlier location. Also, the overlay drawing should appear in screenshots taken using BitBlt or PrintClient by screen-capturing tools like Camtasia, Debut, etc. We need to overlay a target window with a custom shape and tracks the position of the target window such that the overlay drawing always appears above it.
