The ‘data-version’ of these controls required the use of the following properties / methods to bound them to a database field:

Field Property: Stablishes the field that control is bounded to.
Refresh Method: Updates control content based on current field content.
Save method: Updates database file according control content.

Getting Logical

Sometimes, you need to get logical data. from the user. The easiest way to do that, is using a checkbox control.

@ 180, 120 CHECKBOX Check_1

We add it to the program, along with new menu options to set or retrieve its value.

#include "hmg.ch"
Function Main
DEFINE WINDOW Win_1 ;
   AT 0,0 ;
   WIDTH 400 ;
   HEIGHT 300 ;
   TITLE 'Tutor 05 - CheckBox Test' ;
   MAIN
   DEFINE MAIN MENU
      POPUP "First Popup"
        ITEM 'Change CheckBox Value' ACTION ;
              Win_1.Check_1.Value := .T.
        ITEM 'Retrieve CheckBox Value' ACTION ; 
              MsgInfo ( if(Win_1.Check_1.Value,'.T.','.F.'))
      END POPUP
   END MENU
   @ 100, 120 CHECKBOX Check_1 CAPTION 'Check Me!'
END WINDOW
ACTIVATE WINDOW Win_1
Return
