DONE: Single Application Instance

<< < (3/4) > >>

RobC:
I am trying to prevent multiple instances of FireFox.
I tried with SingleInstance, but cannot get it to work (with FF).
Is there a trick as to what I should list in your Options Dialog ?
EG any of these ? 
firefox
firefox.exe
C:\Program Files\Mozilla Firefox\firefox.exe

Thanks,
Rob

Please try this bit of AHK code.  I've written it as a shell hook that should only allow one instance of Firefox to exist.


--- Code: AutoIt ---Gui +LastFoundhWnd := WinExist()DllCall( "RegisterShellHookWindow", UInt, hWnd )MsgNum := DllCall( "RegisterWindowMessage", Str, "SHELLHOOK" )OnMessage( MsgNum, "ShellMessage" )DetectHiddenWindows, OnSetTitleMatchMode, 2 ShellMessage( wParam, lParam ){    WinGetClass, myClass, ahk_id %lParam%        If ( wParam = 1 ) ; HSHELL_WINDOWCREATED    {        If ( InStr( myClass, "MozillaUIWindowClass" ) )        {            WinGet, myList, List, ahk_class MozillaUIWindowClass            If ( myList > 1 )            {                WinClose, % "ahk_id " . lParam            }        }    }}

RobC:
Thanks for that.
Could you advise what program to use to 'compile' it, and how to do it ?
Or, attach a compiled version.
