Exit(0) doesn't terminate script

[c.haslam]

I have written a script that is several thousand lines, accesses functions in several DLLs, uses RichEdit, etc. It uses message-loops for several windows. It works as expected except ...

Problem: When I close the main window, the window disappears and the AutoIt icon disappears from the System Tray, but the script continues to run. I know that it executes Exit(0) because I traced this line. Does anyone have any idea why the script continues to run? That iy is still running is shown by SciTE | Tools: Stop Executing is available, and works. Also Task Manager shows that AutoIt3.exe is still running.

OK. I know the standard advice: simplify the script, and submit the result for a guru to examine. But, in this case, that's easier said than done!

Is there a subtle bug in AutoIt? What could cause AutoIt to continue to run without an icon showing in the System Tray?

Any and all suggestions are most welcome.

0 is the default anyway. What happens when you just use Exit with no error code?

I tried Exit on its own. Same result. Thanks for asking.

Is your script all in one file? Maybe one exits, but another is still running..

Do you handle WM_CLOSE somewhere? (I know this can cause your symptoms)

Have you registered an exit function?

Have you ensured that all the dll's which were opened have been closed? (I don't think this would cause your symptoms but maybe.)

I remember having this problem in a large script and never did find the answer. I assumed it was just something in my code but it went away after the script was compiled so I didn't look any further.

The script is in multiple files. The main file #includes the others. Only the main script is run.

A snippet:

While 1 
$nMsg = GUIGetMsg() 
 If $nMsg > 0 Then 
CopyEditBoxesContentsToDataAr() 
EndIf 
If Not OpenViaMRU($nMsg) Then 
Switch $nMsg 
Case $GUI_EVENT_CLOSE, $mnuProjExit 
If FinishUp() Then Exit(0) 
 EndIf

Sorry for the bad formatting. Don't remember how to make the listing tidy in a post.

There is an OnAutoItExit() function.

You're obviously catching the exit and doing something somewhere in the code.

Anything that anyone tells you will be pure speculation.

It's advised that you create a reproducer that demonstrates the issue if you really want an answer that would help, rather than having everyone chase their tails.

I tried compiling the code. I then ran the resulting .exe. It exited normally.

So it looks like a bug in autoit3.exe or a bug in my code that isn't being caught by the syntax checker, etc. Should this be reported as a bug in AutoIt?

Thats the same experience I had. As to whether it's a bug or not, it's an anomally someplace but I'm not sure where. Like I said it happens rarely.

What happens if you run it without using Scite? Just right-click the script and choose Run Script. It seems to me that with that one script it only happened if I ran it in Scite but I can't be sure because I seldom used Scite back then and even when I did, I usually just used it as a simple editor without the tools.

EDIT: I should also point out the following.

In order to report a bug you have to know where the bug is. AutoIt? Scite?

To report a bug you need a repro script and if there is nothing wrong in your code then that will be difficult to do at best.

As Smoke_N already said: Post a reproducing script here that we also can run to show us the problem.

To add to what Jos and SmOke_N have been saying, you haven't explained why you think Exit(0) isn't working. How did you decide that FinishUp() returned true, or that your exit function didn't start?

[c.haslam]

I accept that, to figure out whether the problem is in my code or in AutoIt, I need to do a lot more checking of my code. I will try to do this over the next few weeks. My approach will be to try earlier versions of the script, to see in which version the trouble began. I was hoping that someone could tell me how the AutoIt icon could disappear from the System Tray and AutoIt3.exe still be running.

I do know that execution continues even when the script is not run from SciTe.

Being an author of GuiRichEdit, I do wonder whether the fault lies in this UDF, perhaps when there are multiple RichEdit controls in a window. Does my Finishup() need to "destroy" each of these controls?

Thanks for the help. I love AutoIt!

This bug is already known. #1319

You have to add _GUICtrlRichEdit_Destroy on exit (OnAutoItExitRegister)

[c.haslam]

ProgAndy, many thanks for the fix.
