Bluesmaster Posted July 8, 2013 Share Posted July 8, 2013 (edited) Hi, I am drawing on the windows task bar with GDI. The Problem: I cant remove what I have drawn, because I cant get the taskbar to refresh. Every other window can receive a WM_Paint Message. Not so the task bar (and the desktop btw) What to do here? expandcollapse popup#include <WinAPI.au3> #include <SendMessage.au3> #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <GDIPlus.au3> _GDIPlus_Startup() Sleep(150) $hDC = _WinAPI_GetWindowDC( 0 ) ; DC of entire screen (desktop) $hGraphic = _GDIPlus_GraphicsCreateFromHDC( $hDC ) _GDIPlus_GraphicsDrawString( $hGraphic, "deleting...", @DesktopWidth - 400 , @DesktopHeight - 18 ) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_Shutdown() ; Remove STRING ???????? Opt('WINTITLEMATCHMODE', 4) $hWnd = WinGetHandle( "classname=Shell_TrayWnd" ) ; 1 Nope... _SendMessage( $hWnd , $WM_PAINT , 0 , 0 ) ; 2 Nope... _SendMessage( $hWnd , $WM_ERASEBKGND , 0 , 0 ) ; 3 Nope... _WinAPI_RedrawWindow( $hWnd ) ; 4 Nope... $paint = DllStructCreate("int;int;long;long;long;long;int;int;byte[32]") DllCall("user32.dll", "int", "EndPaint", "hwnd", $hWnd , "ptr", DllStructGetPtr($paint)) ; 5 Nope... WinSetState( $hWnd, '' , @SW_RESTORE) ; 6 Nope... WinSetState( $hWnd , '' , @SW_SHOW ) Thank you very much regards Bluesmaster Edited July 8, 2013 by Bluesmaster My UDF: [topic='156155']_shellExecuteHidden[/topic] Link to comment Share on other sites More sharing options...
