Hi,I am using crw4.6 comes with vb5.0. I've noticed that the visual linking for 2 tables can only based on 1 field. But I have tableA and tableB, the unique key of these 2 tables is : field1+field2. In vb5 program, I can use sql " where tableA.field1=tableB.field1 AND tableA.field2=tableB.field2 " or " tableA INNER JOIN tableB ON tableA.field1+tableA.field2=tableB.field1+tableB.field2" But how to do the linking in crw4.6? Please help me if you have any idea. Thanks a lot.
