Pass variable from one function to another

[mahsaad]

Hello all,

I've read all the related topics, didn't find one to my question, so here it is

Consider this scenario:

;main au3 file

Opt("GuiOnEventMode", 1)

$main=GUICreate("Test", 200, 200)

$ticket_gui_btn = GUICtrlCreateButton("Ticket GUI", 10, 10, 50, 30)

GUICtrlSetOnEvent(-1, "ticket_gui")

#include <ticket.au3>

GUISetState(@SW_SHOW)

While 1
Sleep(1000) ;Idle around
WEnd

func close_func()
;bla bla bla
endFunc

;another file: ticket.au3

Func ticket_gui()

$child_gui = GUICreate("Test", 200, 200)

GUISetOnEvent($GUI_EVENT_CLOSE, "close_func")

$ticket_input = GUICtrlCreateInput("", 10, 10, 140, 23)

$send = GUICtrlCreateButton("Send", 10, 40 , 90, 25)
GUICtrlSetOnEvent(-1, "verify_gui")

GUISetState (@SW_SHOW, $child_gui)

endFunc

Func verify_gui()

$ticket_value=GUICtrlRead($ticket_input, 1)

if ticket_value="" then
msgbox(0, "error", "Ticket is empty")
endif

endFunc

If i declare the $ticket_input as a global variables outside the 2 functions, the variable $ticket_input is visible in the verify_gui() function and it works fine of course

My question: Is there an alternative instead of declaring it as a global variable?

PS: i have to many child windows and variables. And functions (gui and the verification ones) must be separate as the example above

Thanks guys

Update

For the ones who are suggestion using global variables, i'm already using that, i'm looking for an alternative solution

Using a message loop won't work since i'm using

Opt("GuiOnEventMode", 1)

If using global variables is the solution so be it, but i would like to read your opinion

Something like this?

$variable = "It's me mario!"
_ShowMyVariable($variable)

Func _ShowMyVariable($passed_variable)
MsgBox(0,"","Your passed variable is: " & $passed_variable)
EndFunc

Hi!

[wakillon]

Use a Global variable : Global $Variable

and you can use it in the entire script.

Hi!

Thanks for the reply

Your example the $variable = "It's me mario!" is outside a function, in that way it can be passed as a parameter in the function

In my case the variable is in a function and i want to see it in a second function

mahsaad,

the variable is in a function and i want to see it in a second function

Then declare the variable in Global scope or code in MessageLoop mode and pass it as a parameter.

Like this?:

_First_Function()

Func _First_Function()
$variable = "It's me mario!"
_Second_Function($variable)
EndFunc

Func _Second_Function($passed_variable)
MsgBox(0,"","Your passed variable is: " & $passed_variable)
EndFunc

I'm using

Opt("GuiOnEventMode", 1)

can't use message loop with that

Look at my previous example

[Melba23]

mahsaad,

You have only those 2 choices: Global or MessageLoop. Your choice as to which you wish to use.

Although martin did produce a UDF to enable parameter use in OnEvent if you want to try it.

[mahsaad]

Like this?:

_First_Function()

Func _First_Function()
$variable = "It's me mario!"
_Second_Function($variable)
EndFunc

Func _Second_Function($passed_variable)
MsgBox(0,"","Your passed variable is: " & $passed_variable)
EndFunc

Thanks again,

That won't work either, the second function must be triggered when the button in the first function is pressed

Thanks any way

Thanks for the reply

I know about the udf, thanks for the suggestion, and i think those are the only solutions

I already started with global variables so i guess i'll continue that way

Plus the variables will be used in more than one function, in case i change the variable name, it will be easier to change it in one place instead of changing the parameters in all functions/files

mahsaad,

i think those are the only solutions

So my telling you exactly that twice already in this thread does not really convince you?
