Hi all,

I have an app that sits on 2 servers and "polls" a table for records newly added to a table (these records then form the basis for a report). The app checks every 3 seconds by doing a SQL select against the table (to make it easy to order the reports by "submit time" which is stamped on the record as they are submitted).

The problem is that it sometimes takes from 15 to 30 seconds for the polling app to pick up these records - there is a big lag between when the user submits the records via their desktop app and when the SQL statement actually returns some records to be processed.

Secondly, sometimes a record is picked up by the SQL statement as one to be printed and then when it prints, it is missing some of the memo field data on the report - as if VFP still does not "see" all the data for this record.

Any ideas?

Albert
