You can use GetAliasParams method of TSession: Session.GetAliasParams(AliasName, StringList) or DbiGetDatabaseDesc of DBIProcs:
uses DBIProcs, DBITypes; ... procedure TForm1.Button2Click(Sender: TObject); var StringList: TStringList; DbDes: DBDesc; begin StringList:=TStringList.Create; try Check(DbiGetDatabaseDesc(PChar(AliasName2.Text), @DbDes)); with DbDes do begin StringList.Add('Driver Name: '+szDbType); StringList.Add('AliasName: '+szName); StringList.Add('Text: '+szText); StringList.Add('Physical Name/Path: '+szPhyName); end; ListBox2.Items:=StringList; finally StringList.Free; end; end;
