I am trying to start a dbx objectdocument to open a drawing, but I keep on getting an error msg "Problem loading application". I am using ACAD2004, I tried to register the axdb16.dll but I got the error "the dllregisterserver entry point was not found". I selected the ObjectDBX common 16 type library on the references box. if I run this code, I get an error "problem loading application". Can someone tell me how to do this properly? Thanks Public Sub TestDBX() Dim DbxDoc As New AXDBLib.AxDbDocument Set DbxDoc = Application.GetInterfaceObject("AXDBLib.AxDbDocument") End Sub
