1824	$GUI_BKCOLOR_TRANSPARENT not working in GUICtrlCreateCheckbox	avechuche		"I have a problem or bug (?). I have a GUI with a background image, and need a transparent checkbox, but the ""special flag"" GUICtrlCreateCheckbox, not working. my au3 line is:
...
GUICtrlCreatePic(""picture.jpg"", 0, 0, @DesktopWidth, @DesktopHeight)
GUICtrlSetState(-1, $GUI_DISABLE)
...
GUICtrlCreateCheckbox(""xxxx"", 10, (@DesktopHeight - 100), -1, 20)
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)
...

In ""Autoit Help"" say this in GUICtrlSetBkColor section

""The special flag $GUI_BKCOLOR_TRANSPARENT can be used with the Label, Group, Radio, '''Checkbox''' to apply to them a transparent background color"".

My solution?
GUICtrlCreateCheckbox("""", 10, (@DesktopHeight -100), 13, 13)
GUICtrlCreateLabel("""", 30, (@DesktopHeight - 100), 122, 13)
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)

But is very irritating i have many checkbox :(
