      Good morning everyone

      I was playing a little bit with "Screen Capture" UDF, and I was trying to make a "Window" capture, but, since I made a GUI which through I fire the event "Capture", my GUI is captured as well, and I don't want to
      This is the line of code that makes the capture:
       
      _ScreenCapture_CaptureWnd($strScreenCaptureFileName, $objActiveWindow, 0, 0, -1, -1, False) And these are the lines of code which select the "active" window:
       
      Local $objCurrentWindow = 9999 If _IsPressed("01") Then $objCurrentWindow = WinGetHandle("[ACTIVE]") If $objCurrentWindow <> $objMyGUI Then $objActiveWindow = $objCurrentWindow EndIf EndIf Sorry If I made stupid mistakes
      Thanks in advance.

      Hello,
      i am searching for a function that allows me some very specific functions for Screen Captures.
       
      First should be the possibillity to create a Screenshot from a specific window and this is possibly under another window but has to stay there and not getting forced to be in the first - layer position if this is clear enough :-) The other thing should be the ability to create a Screen Capture every couple minutes or a specific period.  
      I tried a lot of Screen Capture tools but neither can do both together.
      Also my try to create my own script with AutoIT failed, because of missing knoweledge about how to use it for this specific reasons, would be very kind if someone can tell me in the first place if this is possible at all and maybe someone has allready an idea about how to realize it?
       
      best regards

      Download:  _WinAPI_MarkScreenRegionAndCapture.au3  (same as above in the code box)
       
      Tested only on Win10 x64 but should work also on other Window versions. If not please reply.

      I don't get why the images I take turns up like this, but it seems to me like the screenshot doesn't go from the actual positions specified. It's weird, cause what happends is that when I for example move the mouse over the number 25 on SciTE, the image shows that it's over 19... Anyone knows what I'm doing wrong?
