You were attempting to execute a method or assign a value to a property that is usually valid for the object, but is not supported in this specific instance. For example, the Edit method is generally valid for Recordset objects, but not for a snapshot-type Recordset. This error could also occur in cases where the operation is not permitted due to the type or status of the object as when trying to use the MovePrevious method on a forward-only type Recordset. Some operations are also not supported, depending on if you are accessing a Microsoft Jet or an ODBC data source.
