Hide program in taskbar

[jerem488]

Hello,

I want to launch my program (not an autoit program), maximised, and I want he doesn't appear in the taskbar.

I have see the $WS_EX_TOOLWINDOW option, but it's for guicreate command.

How to do this ??

Thanks in advnace

The desktop is just another window (i.e. "[CLASS:Progman; TITLE:Program Manager]"). The taskbar is just a toolbar control on that window (i.e. "[CLASS:ToolbarWindow32; INSTANCE:3]"). The applications on the taskbar are just buttons on that toolbar control (i.e. use _GUICtrlToolbar_ButtonCount()). You can get references to those buttons and change their Hide/Visible state with regular AutoIt UDFs (i.e. _GUICtrlToolbar_SetButtonState()).

Demos for this have been posted before. Note there is an additional step of getting the CommandID of the button on the toolbar with _GUICtrlToolbar_IndexToCommand().

Edit: Added details.

Yes thank you but I haven't find the solution in forum. I'm sure the solution was already post...

Try this. It was for a system tray icon, but the same principle applies. The system tray and the task bar are just two different toolbar controls.

Note the instance numbers of the control can change. On this system for example, the system tray is ToolbarWindow32 instance 1, the Windows Search control is instance 2, and the task bar is instance 3.

It's a (ex)style, you can set it also for other windows:

#include <Constants.au3>
#include <WindowsConstants.au3>
#include <WinAPI.au3>
;

$hWin = WinGetHandle("My App")
_WinSetStyle($hWin, -1, $WS_EX_TOOLWINDOW)

Func _WinSetStyle($hWnd, $nStyle = -1, $nExStyle = 0)
    If Not IsHWnd($hWnd) And Not WinExists(HWnd($hWnd)) Then Return SetError(1, 0, 0)
    
    Local $iWinState = WinGetState($hWnd)
    Local $iFlags = BitOR($SWP_SHOWWINDOW, $SWP_NOSIZE, $SWP_NOMOVE, $SWP_NOZORDER)
    
    If $nStyle = -1 Then $nStyle = BitOR($WS_MINIMIZEBOX, $WS_CAPTION, $WS_POPUP, $WS_SYSMENU)
    
    If BitAND($nExStyle, $WS_EX_TOOLWINDOW) And BitAND($iWinState, 2) Then WinSetState($hWnd, "", @SW_HIDE)
    
    _WinAPI_SetWindowLong($hWnd, $GWL_STYLE, $nStyle)
    _WinAPI_SetWindowLong($hWnd, $GWL_EXSTYLE, $nExStyle)
    
    _WinAPI_SetWindowPos($hWnd, 0, 0, 0, 0, 0, $iFlags)
    
    If BitAND($nExStyle, $WS_EX_TOOLWINDOW) And BitAND($iWinState, 2) Then WinSetState($hWnd, "", @SW_SHOW)
EndFunc

I found a good script for hiding taskbar items. I know it works in Vista x64.
