>In my app I need to create postscript files of drawings for viewing in a workflow signoff process. Before the initiator can effectively pass a drawing to the next step the postscript files must exist. These postscript files are generated by using Run command(WScript.Shell) to act on a plot process in our Cad system. Sometimes the process takes a while. In order to make sure the ps files have the proper name which the plot process can't do, foxpro has to give it a name. This means that the run has to complete before naming, coping, deleteing old file, do over with all sheets. Anyway while this is going on the user is stuck from a few seconds(noy bad) to minutes(not so good). Do any of you have sugestions?

You can use my API_APPRUN class to start a process asynchronously and check it's progress and determine when it terminates by intermittently polling the status, as well as offering synchronous processing. It's in the Files section.
