>I've used USE...NOUPDATE for years to access a group of dBase compatible tables. Now I want to use the CursorAdapter class in VFP 8 but I have to be sure it won't modify the table header when it opens the table. These tables are part of a vertical market application so I don't have any control over their structure. I just want to query them without making any modifications.

There're three properties in CA that you've to set to prevent any updates to data source

AllowInsert = .F.
AllowUpdate = .F.
AllowDelete = .F.
