Hi Frank,

>In mutiuser environment, if a user locked a database as Exclusive (Reindex) then another user tried to load a form which dataenvironment tried to open the same table. I set the "SET REPROCESS TO 1" and trap the error, but I can not release or destroy the form loading process. Since the CDataEnvironment is calling DataEnvironment::OpenTables() which we have no control on its internal routine.

Try this in your error routine

case nerror= whaterver access denied is
messageb('AccessDenied')
return to MyMainPRG
