I have a main app that was written in vb.net. I also have routines for a specific quarter that were written in vb6. I've managed to consolidate the vb6 routines for specific quarter into a dll which can be called from vb.net. I now need to know if it is possible to include a MDB file into the dll; we have several mdb files with the same name that contain data for specific quarters. We to include the mdb file relating to the specific quarter to the appropriate dll file. Would anyone know if this is possible? And if so, how would it be done?
