SYMPTOMS

The Microsoft FoxPro menu program works in the development version of FoxPro. However, if you are using the distribution version of the files (a stand-alone executable), the menu appears, then the application exits to the main operating system environment, either MS-DOS, Windows or the Macintosh desktop.

CAUSE

When a menu is generated, running the .MPR file does not put you in an event loop or a wait state.

RESOLUTION

Incorporate a Foundation READ command into the application.

NOTE: Although the Foundation READ can be used in Visual FoxPro, the preferred method is to incorporate a READ EVENT.

MORE INFORMATION

Foundation READ

To incorporate a foundation READ command in an application, do the following:

  1. In FoxPro 2.x, in the Setup section of the menu or program, include the following code: 
          PUBLIC m.xxx
      m.xxx = .F.
    In Visual FoxPro, in the Cleanup section of the menu or program, include the following code prior to any other code: 
                  READ EVENTS
  2. In FoxPro 2.x, in the Cleanup section of the menu or program, include the following code prior to any other code: 
          READ VALID m.xxx
  3. In FoxPro 2.x, execute the following code when the user chooses the Quit menu option: 
          m.xxx = .T.
      CLEAR READ ALL
    In Visual FoxPro, execute the following code when the user chooses the Quit menu option: 
                  CLEAR EVENTS
For additional information, see the EX1.PJX example in the GOODIES\FNDATION subdirectory and the section on the READ command in the FoxPro version 2.0 "Commands & Functions" or the FoxPro version 2.5 "Language Reference" manual.
