MailSlot help

[zeffy]

I am trying to run a semi-multithreaded application that checks to see if a game is running, and then attaches to it with NomadMemory

at startup, the script opens another instance of its self with

$dpid = Run(@ScriptName & " /detect")

which runs

If $CmdLine[0] > 0 Then
    If $CmdLine[1] = "/detect" Then
        While 1
            _MailSlotWrite($sMailSlot, "0")
            ProcessWait("game.exe")
            _MailSlotWrite($sMailSlot, "1")
            ProcessWaitClose("game.exe")
            _MailSlotWrite($sMailSlot, "0")
        WEnd
        Exit
    EndIf
EndIf

Then the While loop on the parent process checks during every loop to see if the game has been run/closed with

While 1
    $RunStatus = _MailSlotRead($sMailSlot, 1)
    If $RunStatus <> $RunStatus2 Then ;<-- Edit: I forgot to mention that $RunStatus2 is declared earlier in a part that I didn't post which is $RunStatus2 = _MailSlotRead($sMailSlot, 1)
        If $RunStatus = 1 Then
            GUICtrlSetData($Label3, "The game is running")
            GUICtrlSetColor(-1, 0x008000)
            $gpid = ProcessExists("game.exe")
            $ah_Handle = _MemoryOpen($gpid)
            $RunStatus2 = $RunStatus
        ElseIf $RunStatus = 0 Then
            GUICtrlSetData($Label3, "The game is not running")
            GUICtrlSetColor(-1, 0xFF0000)
            _MemoryClose($ah_Handle)
            $RunStatus2 = $RunStatus
        EndIf
    EndIf
...
WEnd

But for some reason, it never changes the label on the GUI, does anyone know why? Thanks

Still nothing?

Could you post a (short) code that could actually be run and that would fail the same way this fails?

Without that here's my guess.

The way you put things _MailSlotRead($sMailSlot, 1) reads binary. That means that $RunStatus is never 1 nor 0. It's 0x31 or 0x30.

Solution could be:

_MailSlotRead($sMailSlot, 1, 1)

Then you will have 1 or 0 (ANSI).
