I am working on a screen capture program and in a loop, i need to get all of the hWnd of each window on the pc. For example, i have four screens i use with my pc. So in the loop i could get the hWnd of each screen. If i am on a pc with only one screen then the loop would only run one time.

I am currently using GetDesktopWindow but that only allows me to capture screen 1.

Hi Basicfarmer,

AFAIK if you use one desktop spreaded over multiple monitors there's only one desktop window - you can check this using i.e. Spy++ which comes with VisualStudio.

So IMO using GetDesktopWindow is the way to go, you only need to find the areas within the desktop window used per monitor. To do so you can use EnumDisplayMonitors which calls a user defined callback functions once per monitor passing the monitor's rectangle.

Hope this helps,

ZOPPO
