Delphi 11 Front end to Cache Database

Hi,

Any examples please of connection a Delphi 11 Front end to a Cache database?

I can get it to connect but then when I try and view data it fails

4 fields in front end

SERVER = 127.0.0.1

PORT = 1972

NAMESPACE = DROP DOWN LIST (I SELECT "DEVELOP" FROM THE LIST

EDIT_CLASSNAME = Default value is Test (with maybe 3 fields just of random stuff)

procedure TFMAIN.BtnConnectClick(Sender: TObject);
 var
 ConnectString: string;
 Success: Boolean;
 Col,Row:Integer;
 FieldName:array[0..10] of string;
begin

    IF NAMESPACE.TEXT<='' THEN
     BEGIN
      SHOWMESSAGE('Please select a Namespace from the drop down list');
      NAMESPACE.SETFOCUS;
      EXIT;
     END;
    //Create instance of the TFactory object
    Factory :=  TFactory.Create(nil);
    //Establish connection with the server if there is no connection
    if not Factory.IsConnected then
     BEGIN
      {
       You can explicitly specify the connection string:
       cn_iptcp - connection protocol
       127.0.0.1 - Ip or sever name(Local Server)
       [1972]      - Port number
       DEVELOP     - Namespace
      }

      //ConnectString := 'cn_iptcp:127.0.0.1[1972]:DEVELOP';
      //ConnectString := 'cn_iptcp:127.0.0.1[1972]:DEVELOP:User:Pass';
      ConnectString := 'cn_iptcp:'+SERVER.TEXT+'['+PORT.TEXT+']:'+NAMESPACE.TEXT;
      Success := Factory.Connect1(ConnectString);
     END;

    if not Success then
     begin
      ShowMessage('Could not connect!');
      //Close the application if the connection fail.
      //Application.Terminate;
      BtnOpenObject.Enabled:=FALSE;
      EXIT;
     end;

    outputMemo.Text := 'Connected to '+ConnectString;
    BtnOpenObject.Enabled:=TRUE;
end;
