Stop Processing on Click

Recommended Posts


Hello everyone! I ran into a problem last night while trying to include a "Stop" button on my GUI based application. While I don't have the code handy to post with me now, I'll try my best to explain using sample code.

I have an application that processes images located in a directory. The GUI includes a ListBox for selecting the folder to process and a start button. After selecting a folder and clicking the start button the application processes all of the images. What I wanted to do was change the Start button to a stop button, redirect the OnEvent function to a stop function and stop the image processing.

Something like this:


While 1
Func ProcessImagesGo()

  GUICtrlSetOnEvent($processbutton, "ProcessImagesStop")

  For Image in Images

    If $CancelImageProcessing Then

      GUICtrlSetOnEvent($processbutton, "ProcessImagesGo")
      $CancelImageProcessing = False


    ;Processing of Images Goes Here


  GUICtrlSetOnEvent($processbutton, "ProcessImagesGo")


Func ProcessImagesStop()

  $CancelImageProcessing = True


When I run the code and click the processbutton while the ProcessImagesGo function is running nothing happens until after all of the images have been processed (the For loop completes). Does anyone know of a way to allow me to stop the processing?

Thanks in advance!

- Josh

The Interrupting a running function tutorial in the Wiki will explain why you are having this problem and suggest several possible solutions to solve it. ;)

As you are running a loop in the function to be interrupted, you should have no problem at all - but come back if you run into difficulties integrating a solution into your script. :huh2:

I thought I searched everywhere before posting the question although I missed the d@mn wiki... Silly me.

Thank you VERY much for your assistance - the wiki page is exactly what I was looking for! :huh2:
