Don't know if a but with GuiOnEventMode, just reporting it

[Newb]

As I said I know what's the error and how to solve it, just reporting it to take a review before submitting it as a bug (because maybe it's not). Seems more parser don't like it, and i thought you MVP's wanted to know about it

Here's the code

GUICreate("Form1", 600, 482, 192, 124)
$Button1 = GUICtrlCreateButton("Numeri", 48, 32, 169, 65)
$Button2 = GUICtrlCreateButton("Lettere", 264, 32, 193, 65)
$Label1 = GUICtrlCreateLabel("", 16, 128, 572, 348)
GUISetState()
Opt("GUIOnEventMode",1)
GUISetOnEvent(-3,_Exit())
While 1
Sleep(100)
WEnd

Func _Exit()
Exit
EndFunc

Problem is in

Opt("GUIOnEventMode",1)
GUISetOnEvent(-3,_Exit())
While 1
Sleep(100)
WEnd

Which should be

Opt("GUIOnEventMode",1)
GUISetOnEvent(-3,"_Exit")
While 1
Sleep(100)
WEnd

to run properly.

Autoit doesn't show the _Exit() without " " as an error and even the while loop doesn't run properly. Don't know the mechanism behind this, but maybe you wanted to be warn about it.

Peace.

I guess this is how it should be an no bug at all. Look at the example:

GUICreate("Form1", 600, 482, 192, 124)
$Button1 = GUICtrlCreateButton("Numeri", 48, 32, 169, 65)
$Button2 = GUICtrlCreateButton("Lettere", 264, 32, 193, 65)
$Label1 = GUICtrlCreateLabel("", 16, 128, 572, 348)
GUISetState()
Opt("GUIOnEventMode",1)
GUISetOnEvent(-3,_Exit())
While 1
Sleep(100)
WEnd

Func _Exit()
    ConsoleWrite("Called ""Exit"" :-) ")
    Return "_myExit"
EndFunc

Func _myExit()
    Exit 77
EndFunc

The function call in "GuiSetOnEvent" Just calls the "_Exit" Function. Whatever you defined happens. In your case it just exited the script.

Try this snippet out, it shows what it is that is happening.

GUICreate("Form1", 600, 482, 192, 124)
$Button1 = GUICtrlCreateButton("Numeri", 48, 32, 169, 65)
$Button2 = GUICtrlCreateButton("Lettere", 264, 32, 193, 65)
$Label1 = GUICtrlCreateLabel("", 16, 128, 572, 348)
GUISetState()
Opt("GUIOnEventMode", 1)
GUISetOnEvent(-3, _NoExit())
While 1
    Sleep(100)
WEnd
Func _Exit()
    Exit
EndFunc   ;==>_Exit
Func _NoExit()
    Return "_Exit"
EndFunc   ;==>_NoExit

When you write it like the way you did, it calls the function _Exit looking for something to be returned. Because it immediately exits, there's no return from it.
