strange gui freeze when exiting

[gcue]

hello all.

i have a parent gui that opens a secondary gui. if i close out of the secondary gui first then close out of the primary gui, it exits fine. however, when i exit the primary gui without exiting the secondary gui, the secondary gui exits but the primary gui freezes and never exits..

primary gui exit function:

Func _Exit()
   Exit
EndFunc

secondary gui and exit:

expandcollapse popup

gcue,

It is impossible to debug the realtionship between the exit behaviour of the 2 GUIs when all you have given us to work on is 2 snippets. Please write a short working reproducer script with just the 2 GUIs and their exit code - then we can see what is going on and offer some sensible advice.

Or you could look at the Managing Multiple GUIs tutorial in the Wiki and see if that helps you solve it yoruself first.

sorry about that - i'll try to piece in more items...

was hoping something in the secondary gui code would have shown the reason

kinda hard to pick out from 27,935 lines =)

gcue,

All you should need to provide is the GUICreate/GUISetState lines and the exit code lines for the 2 GUIs - or else your problem comes from elsewhere in those many lines.

hmm even the primary GUI is 300 lines to create. hah!

strange thing is that i open other GUIs within the primary gui, it exits normally..

let me look closer to see if theres any conflicting calls between both scripts

[gcue]

looks like its this section below. once i remd that out the guis exit normally.

i thought it was maybe the text limit so i reduced it to 99999 but i still have the problem...

i also removed the last two lines - same issue...

$migrator_status_edit = _GUICtrlRichEdit_Create($migrator_child, "", 10, 420, 500, 115, BitOR($ES_MULTILINE, $WS_HSCROLL, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_SetLimitOnText($migrator_status_edit, 99999)
    _GUICtrlRichEdit_SetFont($migrator_status_edit, 9, "Courier New")

this happens before anything happens to that edit control..

i can duplicate the same behavior each time

open primary gui

open secondary gui (that has the richedit control)

close primary gui

secondary gui closes and primary gui hangs

any ideas?

gcue,

any ideas?

Yes.

I seem to remember a bug report somewhere which mentioned that you need to destroy RichEdit controls with _GUICtrlRichEdit_Destroy before exiting the script or the script crashes. Try to add that to your script and see if it helps.

[gcue]

that worked!

hmm hopefully they fix that bug soon.. have you heard if theres a fix out? or soon to be out?

many thanks melba!

[gcue]

nevermind i found it

http://www.autoitscript.com/trac/autoit/ticket/1319

thanks again!

[Melba23]

gcue,

Still an open ticket here #1319.

Edit: You beat me to it!

When a Gui freezes on exit I always first look for resources I did not properly release (gdi+ objects, imagelists...).

Edit: Upsa, that happens when you start a reply, leave the computer for a while and then you submit it anyhow ...

Hi,

when i created a tool with 2 gui together i use to face the same kind of issue..(like my whole desktop got frozen). i used the below function on my Exit function which resolved my issue... I am not sure but this may trigger you guys some idea!

WinActivate("", "")
