Transparent background of a label aren't shown or are grey

[jlorenz1]

TransparentLabel.au3I have a working script with surprising resultats, but without the intended solution. It's very easy: For a GUI window with a picture background I want to create a label with white font and a transparent background of the label, so that you can see the backgroundpicture of the GUI window.

My script can make parts of the background picture transparent, but the background of the labels appears grey or aren't shown.

And now in German. Ich habe ein funktionierendes Skript, das Teile des Hintergrundbildes eines GUI Fenster transparent setzt. Dies war aber nicht Absicht. Vielmehr wollte ich den Hintergrund des Labels

transparent machen, so daß man auf das dahinter liegende Hintergrundbild des GUI-Fensters sehen kann.

Es ist stark vereinfachtes Skript, probiert aus. Ihr werdet überrascht sein. Entweder wird das Label überhaupt nicht gezeigt oder der Hintergrund des Labels erscheint immer hellgrau. Wie schaffe ich dass daer Hintergrund des Labels transparent wird (Auf transparente Bildern mit Texten möchte ich nicht zurückgreifen)

Thanks in advance fo0r your help/ Im voraus besten Dank für Eure Hilfe Johannes

Sorry but I get the error message "Line 15 (File "J:\antwort.au3"):

GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)

GUICtrlSetBkColor(-1, ^ ERROR

Error: Variable used without being declared.

I looked up in the GUIConstants.au3 and didn't find a declaration of this variable
