Is it possible to do?

[SirDarknight1200]

I was thinking if it is possible :

When I first open my script it will show a msgbox/gui etc.... but other time I'll run it it won't show it

Example :

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

MsgBox(0, "Test", "Welcome to my project") ;~It will only be shown on the first run of this app 

$Form1 = GUICreate("Form1", 448, 276, 321, 124)
$Button1 = GUICtrlCreateButton("This is a button", 56, 104, 329, 81)
GUISetState(@SW_SHOW)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

    EndSwitch
WEnd

One solution is create a file so your script can tell if it is the first run.

Example :

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

$myFile = @ScriptDir & "\MyFile.dat"

If Not FileExists( $myFile ) Then
      MsgBox(0, "Test", "Welcome to my project") ;~It will only be shown on the first run of this app 
      FileWrite( $myFile, "Already run" )
EndIf


$Form1 = GUICreate("Form1", 448, 276, 321, 124)
$Button1 = GUICtrlCreateButton("This is a button", 56, 104, 329, 81)
GUISetState(@SW_SHOW)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

    EndSwitch
WEnd

_Singleton() is your friend here.

If both your apps would run at the same time then the app can change operations for when it is run at the second time or third...

_Singleton would help you in this case as Orbs suggested.

If both your apps won't run at the same time then you would have to have something permanent to find out if the app is already executed before.

for this you can go as Starg suggested. Other alternatives are writing to the Registry or INI file, having a server-check ( Internet connection required )...
