_ScreenCapture on locked workstation is black

[will never learn]

Hi there,

I would like to send out internal statistics in my office by email every night.

Opening the program and sending the email with the picture attached is no problem. But the Screenshot is always just black, because the workstation is locked while the script is running at night (scheduled task).

Any ideas on how to solve this? There is no screensaver active.

Current code for capturing the screen:

#include <ScreenCapture.au3>

Local $hBmp
; Capture full screen
$hBmp = _ScreenCapture_Capture("")
;~ Save bitmap to file
_ScreenCapture_SaveImage("C:\Users\Administrator.SCHMITZ\Desktop\Umsatz-Mail\Statistik.png", $hBmp)

Thanks a lot for your help

You can't capture the screen of a locked computer.

Guess you mean you can't capture something that isn't showing as that is what this UDF does...capture the current screen!
So just ensure the screen you want to capture is shown first.

Ok Thanks. Thats sounds like a very definite answer.

Do I have to unlock the computer or are there other ways around it to make the content available to be saved as an image?
