Yup! If you are using Access XP or above, look at binding all combos and lists to disconnected ADO recordsets. That will help immensely all by itself. After that you will probably need to dive into the dark arts of ADO disconnected recordsets for the form as well. As Charlotte said, WANS are considered a no-no for bound forms in Access. John W.

If you are doing things like populating combo boxes with select statements, each one of them is opening a connection. As I recall, lookups in your tables could do that as well. Access was NOT meant for WAN use, and to make it even marginally reliable in that context, you have to rewrite the UI to eliminate any unnecessary connections to the back end and use a JIT approach to populating lists, forms, subforms, etc. There have been previous discussions on this in the list, so you might take a stroll through the archives and see what you find.

Stand alone, it works great, with 5 or so users it works great, over a WAN with multi users it gets very wobbly and corrupts easily. Decided that it has to be split into FE and BE, which I have done manually and linked up the tables. When the DB opens it populates a listbox with choices for the user as before fine. However when the users selects an option which opens the data-entry form (and associated subforms) I get this lovely error "Error 3048 Cannot open any more databases" on this line sSQL = "SELECT * FROM tbl_FYP_APLID WHERE (((FYPID)=" & lFYPID & ") AND ((tbl_FYP_APLID.APLID)=" & lAPLID & "));" [Forms]![frm_FYP_APLID].RecordSource = sSQL Now I know clearly that I must have too "many databases open", but exactly what the hell does that mean? how did it happen and how can I either 1: increase the amount of DB's I can have open, or close down some of the offending databases? The only clue I have found online is if you don't SET your delcared CurrentDB to NOTHING when you are done with it, But the code in this workbook doesn't work like that at all and the modules that do use SET current DB, does set them to nothing when finished. Most confusing. Can anyone shed some light on this. Sorry about all the questions - working under lot of pressure and learning on the fly. Educational for sure, but I am getting through more and more scotch in the evening!! :) Darryl. -- AccessD mailing list AccessD at databaseadvisors.com http://databaseadvisors.com/mailman/listinfo/accessd Website: http://www.databaseadvisors.com
