So I put this in the very first line of my ON ERROR routine. Now, instead of popping up an error message, I get "Mismatched Pushjmp/ Popjmp" from VFP (this is not a trappable error), and clicking ok causes the program to quit.

Erik,

Ed Leafe of the Codebook forum (http://codebook.leafe.com) offered a solution a few weeks ago. Here is the message.


... I ran across this at my current client's location, and came up with this fix. It involves adding code to the Error() method of cDataEnv's cDataEnvironment class. Here is the code for that method:

FUNCTION Error(nError, cMethod, nLine)
IF nError = 1709
* DBC in use error
SET MESSAGE TO "DBC in use; please wait..."
* Pause for a brief instant before retrying
=INKEY(.1)
RETRY
ELSE
ERROR(nError)
ENDIF

RETURN
ENDFUNC

What this does is trap the "DBC in use" error and pause briefly before retrying to access whatever information it needs (usually a view definition).
