hi,
I've got a problem. I have two tables dBase III, let's say MasterTable and
DetailTable. I have created .cdx index based on expresion:

Field1+str(Field2 , 3, 0)

in DetailTable.
Now I want to meke relation between these tables on Field1 AND Field2.

I'm quite new to CPP and BDE so everything i did is based on help. I wrote
something like this but it doesn't work.

---------------------------------------------------------------
  PChar pszMasterExp;
  IDXDesc DetIdxDesc;
  hDBICur hMastCursor, hDetCursor;

  DbiCloneCursor(MasterTable->Handle,false, false, hMastCursor);
  DbiCloneCursor(DetailTable->Handle,false, false, hDetCursor);

  DbiBeginLinkMode(hMastCursor);
  DbiBeginLinkMode(hDetCursor);

  DbiGetIndexDesc(hDetCursor,0,DetIdxDesc);
  pszMasterExp = DetIdxDesc.szKeyExp;
  DbiLinkDetailToExp(hMastCursor,hDetCursor,0, pszMasterExp);
--------------------------------------------------------------------

Could anyone help me, please?
Thanx a lot in advance.
