How do I set the Tab Background colour so I have the whole lot as #292929? #include <GUIConstants.au3> $Form1 = GUICreate("Form1", 372, 225, 214, 154) GUISetBkColor (0x292929) GUICtrlCreateTab(32, 20, 305, 185) GUICtrlCreateTabItem("tab1") GUICtrlCreateTabItem("tab2") GUICtrlSetResizing(-1, $GUI_DOCKWIDTH+$GUI_DOCKHEIGHT) GUICtrlCreateTabItem("") GUISetState(@SW_SHOW) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd
