Lock taskbar

[Anzelm]

ControlCommand("[CLASS:Shell_TrayWnd]", "", "[CLASS:ToolbarWindow32]", "SendCommandID", 424)

Where is the problem, in this Line? I want to lock or unlock the taskbar, but i cant do it.

$retval = DllCall("user32.dll","hwnd","FindWindow","str","Shell_TrayWnd","str","")

if @error then

MsgBox(0,"ERROR","DLLCALL error")

exit

endif

$tray_handle = $retval[0]

MsgBox(0,"TRAY Handle",String($tray_handle))

$tray_handle = WinGetHandle("Shell_TrayWnd")

;$tray_handle = WinGetHandle("classname=Shell_TrayWnd")

ControlCommand("[CLASS:Shell_TrayWnd]", "", "[CLASS:ToolbarWindow32; INSTANCE:3]", "SendCommandID", 424)

This script first show a window, with the number of Taskbar's handle. But it's doesn't matter. After this, i want to send a command, but it's will be crashed the Explorer.exe. Whats wrong in my script? Please help! I begin to try to do it three days ago. I search a lot of thinks with the Google, how to do it with other computer programming language, but i can't do it with Autoit. I tried a lot of combinations, my most success is the crash, because it's the one signal: maybe i sent a message to the Explorer...

I'm sorry for my bad english.

Welcome to the AutoIt Forums !

You can lock Taskbar like this :

AutoItSetOption ( "WinTitleMatchMode", 4 )
Dim $Handle = WinGetHandle ( "classname=Shell_TrayWnd" )
WinSetState ( $Handle, "", @SW_DISABLE )

I think this is what the OP is looking for

#Include <WinAPI.au3>
#include <WindowsConstants.au3>
Local $sLockTaskbar = RegRead("HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced", "TaskbarSizeMove")
$hTrayWnd = WinGetHandle("[CLASS:Shell_TrayWnd]")
If _WinAPI_GetClassName($hTrayWnd) <> "Shell_TrayWnd" Then Exit
If $sLockTaskbar = 1 Then _SendMessage($hTrayWnd, $WM_COMMAND, 424, 0)

I dont know, what can i say to you. Because it's awesome! I want first just unlock the taskbar, but this code is good for it too, because the WM_COMMAND code is same for it. And now, i just have to change the number after the $sLockTaskbar, replace 1 with 0. So finally: thank you, thank you, thank you!!!
