SYMPTOMS

If you issue a DbEngine.RepairDatabase method after you change your project references from Microsoft DAO 3.51 Object Library to Microsoft DAO 3.6 Object Library, you may receive the following error message:
Error # 3251 was generated by DAO.DbEngine.
Operation is not supported for this type of object.
Or, you may notice that the method is not available through IntelliSense when you issue a DbEngine.RepairDatabase method.

CAUSE

In Data Access Object (DAO) 3.6, the RepairDatabase method is no longer available or supported. This is by design to match Microsoft Jet 4.0.

RESOLUTION

If you need this functionality, you can use the CompactDatabase method, which also repairs a Microsoft Jet database.
