>>The treeview does not support natively a multiuser environment -- it is designed for a single user on a single pc; it has no knowledge of someone else changing the node structure on another PC. To enable this, you might try using bindevent (or a timer but it would be delayed) and a communication file. The scenario might go something like this:
>>
>>1. User one opens the form on local PC with treeview; nodes built
>> from shared table; bindevent set
>>2. User two opens the form on local PC with treeview; nodes built
>> from shared table; bindevent set
>>3. User one adds/deletes/changes node; update shared table and update
>> communication file on server with timestamp of change.
>>4. User two bindevent detects change of communication file; re-reads
>> shared table for changes (based on timestamp) and updates local
>> view of treeview.

>>This is repeated by each user. The bindevent would be to a Win32 API that monitors files.

I don't believe that would work. The trigger could respond to the update of the table, but which users have the form open? You would also not have a handle to each of the forms from the stored procedure in which to update the treeview controls. You could use the trigger to write the communication file with a datetime stamp from which each user could respond to.
