In this instance - why not open the tables 'live' (using 'Register Table' rather than 'server link table'). Unless there are pressing needs for you to have TAB files on the PC client - for instance network problems - its much simpler and does exactly what you are describing.
I haven't used the SQL Spatial you've got but this works fine with Oracle and MI Pro/Int Mapping.

I am not sure this will be a recursive problem. If so, probably I will see both messages every loop and probably the system will crash. The reason I have the code in that event is because I have a table with more than 800.000 points and lines, so I only refresh the objects inside the map bounds. (due a perfomance problem) So if the user make a zoom/pan, I refresh only a set of records. The set the user will see on the map. This allow us to work and edit a table with vitually unlimited records. (When the zoom is too big we don't make a refresh). With this in mind, is not practical to press a button each time the user make a pan/zoom. Neither to use a timer. May be with these aclarations you find out another way to help me Regards and thanks again Alejandro > Alejandro > > You have already realised this might be a problem (I think) from your PS but > what might be happening is that you get locked into a spiral by using the > WindowContentsChanged callback - you do a server refresh which itself may > change the contents of the window, resulting in another call etc etc. > > At the very least it might be introducing some instability - its almost > certainly recursing somewhere. > > Your best bet is to do a server refresh on a timer - eg every minute or 30 > secs - or as an explicit statement when you commit an edit ie when you know > there has been a change, rather than in an event handler.
