External Progress Bar Puzzle

[qwert]

I call an AU3 script from an external program so that the AU3 script can put up a Progress Bar for the user while a 30-second operation in the external program takes place. It works fine. However, there are times when the operation finishes in only a couple of seconds. I try to send a Bar Off request to the AU3 script, but it is ignored -- probably because the script does not actually receive the request due to the _Singleton mode that it runs under.

Do I need to abandon the _Singleton approach? I've tested without the _Singleton and the cancel request is received, but I don't know how to make the independent second copy (with the cancel request) cancel the already-running copy servicing the first request. As always, I'm looking for a simple method.

Any suggestions will be appreciated. Thanks.

The simple way would be to create a blank file FileWrite($filename,"") and have the loop where you are progressing the progress bar check to see if the file exists, if it does, exitloop then delete the file.

...create a blank file FileWrite($filename,"") and ... check to see if the file exists

That worked ... and it was easy.

Thanks very much.
