am632 3 Posted August 22, 2011 Hi, I have a simple gui with a button which opens a second window, then when you close the 'child gui' it should just go back to the main gui. here is the script... expandcollapse popup#include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #NoTrayIcon #RequireAdmin Opt("GUIOnEventMode", 1) Opt("GUICloseOnESC", 1) Local $Var = False $Form1 = GUICreate("Main", 456, 313, -1, -1) $LABEL = GUICtrlCreateLabel("Child Window Has not been opened", 80, 40, 310, 28) GUICtrlSetFont(-1, 14, 400, 0, "MS Sans Serif") GUICtrlSetColor(-1, 0x000000) GUISetState(@SW_SHOW) GUISetOnEvent($GUI_EVENT_CLOSE, "_CloseApplication") ;Buttons $BUTTON_CHILD = GUICtrlCreateButton("Child", 184, 144, 75, 25) GUICtrlSetOnEvent($BUTTON_CHILD, "_Begin_Open_Function") While 1 Sleep(0) If $Var Then _Open_Function() EndIf WEnd ;Close Func Func _CloseApplication() Exit EndFunc ;Child Window Func Func _Begin_Open_Function() $Var = True EndFunc Func _Open_Function() $Var = False Opt("GUIOnEventMode", 1) Opt("GUICloseOnESC", 1) GUISetState(@SW_DISABLE, $Form1) $FormChild = GUICreate("Child", 320, 200, -1, -1) GUICtrlSetFont(-1, 14, 400, 0, "MS Sans Serif") GUICtrlSetColor(-1, 0x000000) GUISetState(@SW_SHOW, $FormChild) GUISetOnEvent($GUI_EVENT_CLOSE, "_Close_Child_Window") EndFunc ;Close Child Window Func _Close_Child_Window() GUISetState(@SW_ENABLE, $Form1) GUIDelete($FormChild) EndFunc What it's doing is when you close the child gui it says "$FormChild variable being used without being declaired" and I cant see why its doing this. Can anyone tell me please? Thanks Share this post Link to post Share on other sites

Melba23 2,805 Posted August 22, 2011 am632,The $FormChild variable is only declared in the _Open_Function function when it is created. As you do not specify a scope, AutoIt defaults to the Local scope and the variable is invisible to any other function in the script - so when you try to access it in the _Close_Child_Window function, you get the error. Solution: add the $FormChild variable as Global at the top of your script. By the way, the Local $Var = False is automatically recast as all variables in the main script are Global in scope. And you do not need to repeat the Opt lines in the _Open_Function function - the initial ones are valid for the whole script. All clear?
