How to find if a button is checked or not ?

[ffdshow]

For example, in Windows 7 the option 'Auto-hide the taskbar'.

I use this for check/uncheck the above option:

Opt("TrayIconDebug", 1)
Opt("TrayAutoPause", 0)
Opt("SendKeyDelay", 200)
If @OSBuild >= 7600 Then
   BlockInput(1)
   _ToggleAutoHideTheTaskbarInWindows7()
EndIf
Func _ToggleAutoHideTheTaskbarInWindows7()
   Send( '^{ESC}' )
   Send( '^{ESC}' )
   Send("{APPSKEY}")
   Send("{UP}")
   Send("{ENTER}")
   Send("{DOWN}")
   Send("{SPACE}")
   Send("{TAB 9}")
   Send("{ENTER}")
   Send("{ENTER}")
EndFunc

It will be better first to find if that button is already checked or not.

Regshot 2.0.1.70 unicode can't find registry entries changed when toggle between check/uncheck.

Thanks !

This will check that button if it's not already checked:

Opt("TrayIconDebug", 1)
Opt("TrayAutoPause", 0)
Opt("SendKeyDelay", 200)
BlockInput(1)
_TaskbarHidden()
Func _TaskbarHidden() ; 0 = Shown Or 1 = Hidden
   Local Const $ABM_GETSTATE = 0x00000004
   Local $aReturn
   $aReturn = DllCall('shell32.dll', 'uint', 'SHAppBarMessage', 'dword', $ABM_GETSTATE, 'ptr*', 0)
   If @error Then
   Return SetError(1, 0, 0)
   EndIf
   If BitAND($aReturn[0], 0x01) = 0 Then ; If "Taskbar and Start Menu Properties->Taskbar->Auto-hide the taskbar" is unchecked Then
      Send( '^{ESC}' )
      Send( '^{ESC}' )
      Send("{APPSKEY}")
      Send("{UP}")
      Send("{ENTER}")
      Send("{DOWN}")
      Send("{SPACE}")
      Send("{TAB 9}")
      Send("{ENTER}")
      Send("{ENTER}")
   EndIf
EndFunc   ;==>_TaskbarHidden
