>I have a form that displays individual customers. My application allows users to have multiple instances of this form open at any one time. Each form has a private datasession and has buffering set to 5. The form has the usual step forward and back buttons to allow users to step through customers. The form also has a filter button which calls a modal form to collect criteria for filtering the underlying table. The criteria is returned as a string which is then used to build a temporary index and thereby allow users to filter the underlying table and step through only those customers meeting the criteria.

When I have two customer forms on screen the index command errors with "Command cannot be issued on a table with cursors in table buffering mode (Error 1579)". I have set buffering to 1 before the index is built and reset it afterwards, but this does not help.

In order to add a new index to a foxpro table EXCLUSIVE use of the table is required.
Thus, you cannot use the above strategy in a multi-user situation.

If anyone knows of a technique allowing muliti-user access as a table is being reindexed... let me know.
