Trap Valentina license time limit

[Barry G. Sumpter]

Yes, thanks for that the 
Exception exc as VException

Is easy enough to understand.

The context was related to the database erroring out and me not knowing what
the error was and once the error was found then what other errors should I
be checking for in the same context etc.

And thinking why not just have a single routine that checks thru all errors
and displays a standard format dialog etc.

Please take a look in our examples.

You can do something like this:
Exception exc as VException
  stErrCode.Text = Str( exc.ErrorNumber )
  stErrStr.Text = exc.Message

So  you  have  caught any Valentina exception. And you are able to get
err code and message from that one.
