Window hangs

[telmob]

My main UI window is hanging and i can't find out why.

I just want the script to do something after i close the window. So i open (show) the window and wait for it to be closed to apply settings, but after i show the window, i can't do anything with it, not even close it.

Why?

Case $t_msg = "Configure"
WinSetState($SRPEGUI,"",@SW_SHOW)
WinWaitClose("SRP Enforcer")
$msg=msgbox(36,"Settings Changed","Activate now?")
if $msg=6 then install("update")

I think you need to show a little more code that you have.

[Jos]

Does it get stuck on your winwaitclose?

[telmob]

I think you need to show a little more code that you have.

My code is very simple, but kind of big. I have a GUI and a tray with several buttons. When i press 'Configure' in the Tray menu it opens the main window. So far so good, but then it hangs when waiting for it to close. It waits for the window to close to apply settings defined in the GUI.

Does it get stuck on your winwaitclose?

Yes, exactly.

So, why are you using it then?

[telmob]

So, why are you using it then?

Because it looks like the easy way to do it, ofcourse. What is the alternative?

[Jos]

Well, then you will have to explain what you want to do as i falling short in the clairvoyant department.

[telmob]

I already explained in the above post.

Is there an alternative for WinWaitClose that doesn't hang my GUI?

[BrewManNH]

You really haven't explained it very well, you need to post some more of the code to allow us to figure out what you've done wrong.

Thats my problem, my code is sooo long and dispersed..... I'll try to organize a portion of the code so i can reproduce the error and i'll post it here after.

Thank you

If that window ("SRP Enforcer") is your own gui, then you need to do things differently.

If it is not, then you either have to remove that line or wait for the window to close.

I can only assume the user is supposed to close it, otherwise I don't see the point of it.

Yes, its my own gui. Sorry i haven't been able to post nothing very specific but i'm bashing my head against the wall with so many lines of code.

I have a tray icon with a menu. The menu has an option to 'Configure'. When i press 'Configure' the main gui opens with some settings to chose from, and when i close the gui, the tray menu should update. So:

Case $t_msg = "Configure" ; In case i press configure in the tray menu...
GuiSetState(@SW_SHOW) ; ...the GUI shows
Do
    Sleep(10)
Until Not WinExists("SRP Enforcer") ; When the GUI is closed......
$msg=msgbox(36,"Settings Changed","Activate new settings now?") ; ....it shows this message.

But i cannot close the GUI.......!

I am going to have to assume one last time that you have more than one gui

and that this particular gui is not being polled by a message loop (GuiGetMsg)

Without code to see, the best that can be offered is advice to look at the wiki

where you will find Melba23's great guide on working with multiple gui's.

Best of luck.

I don't. I only have one GUI and the tray menu.

How do you plan on closing the gui if you don't look for the exit message from it?

[telmob]

I'm sorry, i don't understand. What do you mean?

The GUI has an exit button and even a 'minimize to tray' (@SW_HIDE)button, and they work (without the winwaitclose or whatever).

You really are intent on learning the hard way, at least you're consistent.

Anyone else who posted a reproducer code would have had this problem

fixed within 5 minutes.

Where does the script check for the exit condition on the GUI? Because you're not checking in the Do loop, so it will never close, unless you're using OnEvent mode, which it doesn't appear that you are.

[Jos]

With Event mode you need to ensure that the Fired Func isn't hanging either or else the next event will not fire until it completes.

There are a couple of options:

1 setting a variable in the Fired Event Func and returning and then act in the Variable value in the While-Wend loop.

2.do a mix of Event and Message loop.

This is an example of the second option:

expandcollapse popup

#include <GUIConstantsEx.au3>

Example()

Func Example()
Local $Button_1, $Button_2, $msg
GUICreate("My GUI Button") ; will create a dialog box that when displayed is centered
GUISetOnEvent($GUI_EVENT_CLOSE, "SpecialEvents")
GUISetOnEvent($GUI_EVENT_MINIMIZE, "SpecialEvents")
GUISetOnEvent($GUI_EVENT_RESTORE, "SpecialEvents")

Opt("GUICoordMode", 2)
$Button_1 = GUICtrlCreateButton("Wait for window", 10, 30, 100)
$Button_2 = GUICtrlCreateButton("Close", 0, -1)
GUICtrlSetOnEvent(-1, "ClosePressed")


GUISetState() ; will display an dialog box with 2 button

; Run the GUI until the dialog is closed
While 1
     $msg = GUIGetMsg()
     Select
         Case $msg = $GUI_EVENT_CLOSE or $msg = $Button_2
             MsgBox(0, "MsgLoop-Close Pressed","MsgLoop-Close Pressed")
             ExitLoop
         Case $msg = $Button_1
             Opt("GUIOnEventMode", 1)
             GUICtrlSetData($Button_1,"Waiting-hang")
             Winwait("does exixts") ; hanging func
             GUICtrlSetData($Button_1,"Wait for window")
             Opt("GUIOnEventMode", 0)
     EndSelect
WEnd
EndFunc ;==>Example
;
Func ClosePressed()
MsgBox(0, "Event - Close Pressed", "ID=" & @GUI_CtrlId & " WinHandle=" & @GUI_WinHandle & " CtrlHandle=" & @GUI_CtrlHandle)
Exit
EndFunc ;==>CancelPressed
;
Func SpecialEvents()
Select
     Case @GUI_CtrlId = $GUI_EVENT_CLOSE
         MsgBox(0, "Event-Close Pressed", "ID=" & @GUI_CtrlId & " WinHandle=" & @GUI_WinHandle)
         Exit
EndSelect
EndFunc ;==>SpecialEvents

I now understand. It is clear to me now that i should place the 'after-exit' settings in the gui itself instruction after closing it.

Thank you so much for your help and time spent.

I have solved my problem. It was indeed a placement problem. Sorry i couldn't explain any better, but i already have 7000 lines of code and some of it i took from two scripts i found here on the forum, so it was hard for me to extract the portion i was having trouble with.

Again... thank you and sorry for the trouble.

You guys rock!
