Function problem

[Marlo]

OK so i am having a little trouble with my script.

You see i am writing a script with a GUI and whenever i write GUI's i have them use the OnEvent method

Example:

Opt("GUIOnEventMode", 1)

$winMain = GUICreate("app", 640, 260, 193, 150)
$Label1 = GUICtrlCreateLabel("Directory", 24, 66, 83, 17)
$btnAdd = GUICtrlCreateButton("Add File", 160, 216, 75, 25, 0)
GUISetState(@SW_SHOW)

GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")
GUICtrlSetOnEvent($btnAdd, "_ToggleButtons")

While 1

Wend

Func _Exit()
Exit
EndFunc

Func _ToggleButtons($switch = False)
If $Switch = False Then
Do stuff
EndIF
EndFuncoÝ÷ ØÚ0¶¢%x­¶ì~éܶ*'Âä±ø§{^Æ¥çméè®f¥Á¬ºÚ"µÍÕÙÙÛP]ÛÊYJ

But when i call GUICtrlOnEvent($btnAdd, "_ToggleButtons") I get an error "Variable used without being declared.:"

Now i have made the parameter in the function optional but still the error persists. Can anyone shed some light onto this? much apreciated.

You can´t call a function with parameters in GUICtrlSetOnEvent()

You have to use a global variable

Example:

Opt("GUIOnEventMode", 1)

$switch = 0
$winMain = GUICreate("app", 640, 260, 193, 150)
$Label1 = GUICtrlCreateLabel("Directory", 24, 66, 83, 17)
$btnAdd = GUICtrlCreateButton("Add File", 160, 216, 75, 25, 0)
GUISetState(@SW_SHOW)
GUISetOnEvent(-3, "_Exit")
GUICtrlSetOnEvent($btnAdd, "ToggleButtons")

While 1
    Sleep(1000)
Wend

Func _Exit()
    Exit
EndFunc

Func ToggleButtons()
    If $switch == 0 Then
        $switch = 1
    Else
        $switch = 0
    EndIf
    MsgBox(0,"",$switch)
EndFunc
