>I've got a problem with primary keys. They look like "00001", "00002", etc. Anyways I have run into a situation where I have to reuse them. So for example, if the table contains five records, "00001", "00002", "00003", "00004", "00005" and the user deletes "00003" I wind up with "00001", "00002", "00004", "00005". I have to change it to "00001", "00002", "00003" (used to be 00004), "00004 (used to be 00005). I do this with the following code. The order is set to "tid" which is the Primary key.

Any ideas on how to solve the problem without making the primary key not primary? I am working with a treeview active x control and I am using this as a way to identify an item. The treeview source is a table. When the user deletes one, it is deleted from the table. Then I clear the treeview and add all the items all over again. Maybe there is a better way of doing this? It seemed like overkill when I did it, but can't think of any other way as I need to have the primary key matching the key for that item created by foxPro when the treeview is created.

Chris,
Primary keys are for you as an idenifier not for the end user, right ? If so you don't need to make them sequential to work with treeview. IMHO leave as is. Treeview doesn't care they're ordered but just be unique.
