[Solved] _ScreenCapture_CaptureWnd captures my GUI too

[FrancescoDiMuro]

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.

Which way does this gui work ? do you press a button ?

Good morning @mikell
Yes, I just have a file menu and a button on this GUI ( which takes the picture )
Thanks for the reply

Best Regards.

So you're coming into trouble, because pressing the button makes your gui the current active window

Not really

The code 

Local $objCurrentWindow = 9999

If _IsPressed("01") Then
    $objCurrentWindow = WinGetHandle("[ACTIVE]")
    If $objCurrentWindow <> $objMyGUI Then  
        $objActiveWindow = $objCurrentWindow
    EndIf
EndIf

avoid this, but, when I have my GUI in the same "section" of the screenshot, it is included in the screenshot
If I put my GUI on my second screen, the screenshot doesn't have my GUI in it

PS: I see this code from a @Melba23 post Thank you Sir!

So the only workaround I can think of would be : hide the gui, take the picture, show the gui

Already tried! Seems to not work

[mikell]

Hmmm this works for me

#include <ScreenCapture.au3>
#include <GUIConstantsEx.au3>

$hGUI = GUICreate("Screen Capture")
$btn = GUICtrlCreateButton("test", 120, 170, 85, 25)
GUISetState(@SW_SHOW)
    
While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                ExitLoop
            Case $btn
               GUISetState(@SW_HIDE)
               $objCurrentWindow = WinGetHandle("[ACTIVE]")
               _ScreenCapture_CaptureWnd(@desktopDir & "\GDIPlus_Image.jpg", $objCurrentWindow)
              GUISetState(@SW_SHOW)
        EndSwitch
WEnd

causes the "error".
I removed all the "extra" parameters, and now it works perfectly.

Thanks for your help
