_ScreenCapture_CaptureWnd not working without focus

[stmdell]

Hello..

I am trying to use _ScreenCapture_CaptureWnd but have run into an issue.

I have the hWnd of the window that I am tyring to capture and the propper cords of the area I want however, if that window is not active

then the _ScreenCapture_CaptureWnd function seems to only capture the pixes of the top most window on the screen.

For example, I postion the window on the screen and run the code while the app is active using WinActivate($hWnd) and this works great.

Next I position the Scite window on top of the app and move it so that Scite is covering that area of the target app.

When I rem out the line WinActivate($hWnd), what I end up with is a screen capture of Scite and not the target app.

It is almost like _ScreenCapture_CaptureWnd is ignoring the hWnd I passed and only looking at the enitre desktop.

I saw a converstaion on this topic but it does not go into enogh details http://www.autoitscript.com/forum/index.php?showtopic=59591

My main question is... if I am passing a handle why does it matter if the window is ontop of all others? Shouldn't the screen cap still work reguardless of its state (top, normal, maximized, minimized, etc)?

Thank you...

stmdell,

Welcome to the AutoIt forum.

You need to sharpen up your searching skills (although I must admit that the Search function is not the best I have ever seen).

Take a look at this topic - using wraithdu's code from post #6 I have just saved an image of a window which is hidden by others.
