SUMMARY
Visual FoxPro's Online Help for Controls and Objects states:

In Visual FoxPro, a NAME clause has been added to each of the controls created in previous FoxPro versions. The NAME clause creates an object reference for controls created with @ ... GET and @ ... EDIT, allowing you to manipulate the controls with Visual FoxPro properties, events, and methods. The NAME clause provides an intermediate step to upgrade your applications using Visual FoxPro object-oriented programming techniques.

But it does not provide an example. This article will show how to incorporate the NAME clause into a program with @...GETs.



MORE INFORMATION
When using the NAME clause, you can run the control's default methods and events, but you will not be able to write new code for any of methods or events. The only exception is for the WHEN and VALID events because the WHEN and VALID are clauses of the @...GET command. You are able to assign values to any of the objects Properties at runtime.

An important point to remember is that Visual FoxPro creates a PageFrame and a Page to handle the READ level for any @...GET commands in a FoxPro 2.6 program. The page and its controls become active at the READ and terminate when the READ terminates.

For more information on converting to Visual FoxPro see 'Converting from FoxPro 2.6' under Getting Started in the Using Visual FoxPro section of online Help.

Sample Code Showing How to Use the NAME Clause
DEFINE WINDOW mywin NAME MyWin; FROM 1,1 TO 30,50 ; FLOAT ; NOCLOSE ; MINIMIZE ; SYSTEM ACTIVATE WINDOW mywin

@ 3,5 GET a NAME Text1; SIZE 1.4,15; DEFAULT SPACE(15); PICTURE "@K" @ 3,25 GET b NAME Text2; SIZE 1.4,15; DEFAULT SPACE(15); PICTURE "@K" @ 10,5 GET x Name Button1; PICTURE "@*HN Button 1" ; SIZE 2,10 ; DEFAULT 1 ; STYLE "B" ; VALID Validx @ 10,25 GET y NAME Button2; PICTURE "@*HN Button 2" ; SIZE 2,10 ; DEFAULT 1 ; STYLE "B" ; VALID Validy @ 20,15 GET z NAME Button3; PICTURE "@*HN Close" ; SIZE 2,10 ; DEFAULT 1 ; STYLE "B" ; VALID Validz

MyWin.PageFrame1.Page1.Text1.SpecialEffect = 0 MyWin.PageFrame1.Page1.Text2.SpecialEffect = 0 MyWin.PageFrame1.Page1.Text1.BorderStyle = 1 MyWin.PageFrame1.Page1.Text2.BorderStyle = 1 MyWin.Refresh MyWin.Caption = "Window Caption" && Sets the Title Bar Caption MyWin.PageFrame1.Page1.Text1.Value = "Press Button 1" MyWin.PageFrame1.Page1.Button1.Command1.SetFocus
 * The next four lines of code give the @...GETs for the text boxes
 * a 3D look.
 * The buttons become part of a command group. The next line of
 * code sets the focus to Button1.

READ CYCLE RELEASE WINDOW mywin

FUNCTION Validx   &&  x VALID ** Changes the values of the text boxes and the captions ** of the command buttons. MyWin.PageFrame1.Page1.Text1.Value = "Thank You" MyWin.PageFrame1.Page1.Text2.Value = "Press Button 2" MyWin.PageFrame1.Page1.Button1.Command1.Caption = "Press 2" MyWin.PageFrame1.Page1.Button2.Command1.Caption = "Button 2"

FUNCTION Validy   &&  y VALID ** Changes the values of the text boxes and the captions ** of the command buttons. MyWin.PageFrame1.Page1.Text1.Value = "Press Button 1" MyWin.PageFrame1.Page1.Text2.Value = "Thank You" MyWin.PageFrame1.Page1.Button1.Command1.Caption = "Button 1" MyWin.PageFrame1.Page1.Button2.Command1.Caption = "Press 1"

FUNCTION Validz  && z VALID CLEAR READ
