Detect Macro Completion
 

Hi. I wanted to ask if there is a way to detect that a macro has completed (by
completing, an error stopping the macro also counts). I have a VB application
that calls an Excel macro. The Excel macro makes a text file that the VB application
needs to continue, so the VB has to wawit before continuing.

In pseucode, i've done this waiting with a tight loop:

call the macro

While file_i'm_waiting_for doesn't exist
Wend

continue doing what i was doing

The tight loop gets what I need done in good situations, but for example,
if the macro experienced some kind of error that prevented it from completing
making the text file, the VB app will sit in that tight loop forever and just
hang. Isn't there some better way to detect that the macro is completed?
Like some property I can check, e.g. using While WB.active = True instead
of checking that the file exists. (I just made that "active" property up, but you know what I mean).

Thanks.

From what you've written here, I believe that you just need to set an
OnError condition in the macro, so that something actually happens when an
error occurs.

Put error handling in your file create macro and a completion status
variable which is set to false on the way in and true on the way out. The
error handling can force the completion status to False and terminate the
file creation.

The compleion status is then used to control whether the next stage should
run, and if required tell the user if an error occurs and control the ending
of the process.

Make the macro a function and have it return it status. then your code will
wait for it and you can examine the results.

results = Application.run( ... )
