I have created a VBA application written for an access database. This application checks if there is an open application of AutoCAD, opens ACAD if necessary, opens selected drawings, and pulls pertinent information from those drawings into the access database. I have recently discovered a problem with my application where it will freeze. This condition occurs if the ACAD drawing was written with ACAD 2005 and the user of my application has ACAD 2002. ACAD 2002 is not capable of opening these files due to incompatibilities. Is there an error handling procedure that I can use that will capture the error from ACAD, report the error to Access, and continue checking the other drawings? It doesn't need to be pretty. I just need to find a way to keep this from locking the application up. Thanks for any help.
