Compile exe randomly hangs

13 posts in this topic

Hello all,

I recently being getting into Autoit and love it's capability and potentials. I have a business need to logon to 3rd party software on specific machine and will renew the software license for week. I know it's crappy way of how this was arrange by agreement, but I have to make it work somehow and was able to get to work. But now I got a weird problem, when I create the excutable it will all day on my machine and test the machine as well. I made task schedule for auto this.

As you can imagine, the codes are fairly simple.

I works great for the day, but the next day the exe just hangs and will not complete. Here's the other thing, the same one that fail will work again later that day.

I being searching and coming up empty, I am complete at lost with this. Can some PLEASE help or explain to me what me cause this.

Thanks in advance for the great help.

Welcome to the forums!

Your wording is ambiguous. Are you having issues compiling a script, or are you having issues with an already compiled script?

- Scan your system for viruses.

- Uninstall and reinstall the latest stable version of AutoIt.

- Post your code. Your script could be waiting indefinitely for a condition that never exists, and we have no way of knowing what you're trying to accomplish.

Good luck

Thanks for response. Sorry if I sound confusing, it was end of week and was doing 3 things at once :P. Here's the problem I am facing with and I have included the code below, as I said was very basic.

1. I am using AutoIt v3.3.0.0 and we run McAee anitvirus

2. I compile code into excutable program and run the .exe with no problem.

3. I've made XP Window schedule task in to run the my program daily. I've tested it and ran like it should I have schedule the task on my local machine and also a test machine. It all ran great the that day.

Here's the problem, when the task ran the next, it will not complete the task. Instead it just "hangs on the system tray", it appears the send keystroke faile to excute for what reason. This fail on both my local machine and test machine. Anyways, I have included the code below. I hope this clearify my propblem. Thanks again for help.

Code:

;Excute application

Run("\\server\Test\Apps.exe")

;Send keystroke

While 1

If WinActive("Good Morning! Login Please ....") Then

;Sleep (1000)

Send ("keystroke")

Send ("{TAB}")

Send ("{Enter}")

;ControlClick("Intented Application Window", 328, 22)

ExitLoop

EndIf

Wend

;wait for apps window to open and close after 2 second

WinWait("Intented Application Window","")

WinWaitActive("Intented Application Window","")

Sleep (2000)

$handle = WinGetHandle("Intented Application Window", "")

WinClose($handle)

edit: Do a full edit on your original post and changer the title, its a bit misleading as skruge pointed out.

Sorry, that was just extra stuff I've forgot to delete, here's the corrected code. Thanks!

;Excute application

Run("\\server\Test\Apps.exe")

;Send keystroke

While 1

If WinActive("Good Morning! Login Please ....") Then

Send ("keystroke")

Send ("{TAB}")

Send ("{Enter}")

ExitLoop

EndIf

Wend

;wait for apps window to open and close after 2 second

WinWait("Intented Application Window","")

WinWaitActive("Intented Application Window","")

Sleep (2000)

$handle = WinGetHandle("Intented Application Window", "")

WinClose($handle)

On the times when it fails is your window actually active and is the title text actually as given?

WinActive("Good Morning! Login Please ....")

If that title text changes then you will have to set Opt("WinTitleMatchMode", 2)

Example

Opt("WinTitleMatchMode", 2)
$sTitle = "Login Please"
While 1
If WinActive($sTitle) Then

If the window that you are looking for does not exist then you will get exactly what you are seeing now, a loop that will not exit until that window does exist.

Thanks! Login window title does not change, I originally thought that it was delay issue. The code do process the run command part but it seems to stop there and not passing any of the keystroke section. So I manually launch the excutable and sure enough task program hangs in system tray. To make things more complicated, later in the that afternoon, I tried lauching it and it runs pefectly fine...

Any help is greatly appreciated.

Send ("keystroke")

Send ("{TAB}")

Send ("{Enter}")

There's the possibility that another application steals the focus and thus intercepts the keystrokes.

You can use SendKeepActive("Good Morning! Login Please ....") to prevent other apps from taking focus.

However, Send will not work if nobody is logged in or if the workstation is locked. Is this the real difference between your morning/afternoon cases?

A much more reliable way would be to do without Send.

If the keystrokes are being sent to an input/edit field, try ControlSetText/ControlSend instead.

If the "Tab -> Enter" is pressing a button, try ControlClick.

All of the control names should be visible using the AutoIt Window Info Tool. (Au3Info.exe)

Some sort of error handling might give you a better idea where you're failing?

;Execute application
$FileName = "\\server\Test\Apps.exe"
If FileExists($FileName) Then
    $PID = Run($FileName)
Else
    Msgbox(16,"","Can not find server/file")
Endif

;Send keystroke
$timer = TimerInit()
While 1
    If TimerDiff($timer) > 10000 Then
        Msgbox(16,"", "Loop exceeded 10 seconds")
        Exitloop
    Endif
    If ProcessExists($PID) Then
        Sleep(100)
        Send ("keystroke")
        Send ("{TAB}")
        Send ("{Enter}")
        ExitLoop 
    EndIf
Wend

Edit: Skruge has a good idea, I also wonder if it's possible for your app to report as existing, but not be fully loaded and ready for input from the keyboard? Maybe the Sleep above will make a diff?

I suspect that it has to do with the time allowed for WinActive(). using the standard WinWaitDelay you only have 250ms. Take a look at using WinWaitActive() instead of WinActive()

EDIT:

As a second thought, when the script "hangs" take a look and make sure that the proper control has focus. You may have to run the Window spy to get the control IDs and set focus first.

Add Opt("TrayIconDebug", 1) to the top of the script and when you have a hanging script, just hover the Icon to learn where its hanging.

Thanks all for the advice. I have made some few changes base one some of your recommendations and recompiled the program. As expected, it ran perfectly, the big test will be tomorrow morning. I have scheduled the task to run the program in the morning without anyone logging on the machine. I have included the debug part in case the program hangs, hopefully it will help identify the problem.

Two side notes: 1. Is the compile .exe secure? I am concern with hardcoding user name and password and passing it on via keystroke. 2. Any good books I can procure for learning?

Thanks again all for the help. I will let you know if the program ran successfully.

No it is not and you should never use any Domain Admin level account.
