The information in this article applies to:

Microsoft Visual FoxPro for Windows, version 3.0
Microsoft FoxPro for Windows, versions 2.5x, 2.6x

SUMMARY

You can quit Microsoft Windows from within an application written in FoxPro by using the Windows application programming interface (API) through FOXTOOLS.FLL, a library file included with FoxPro.

MORE INFORMATION

NOTE: While it is possible to quit Windows from within a FoxPro program by making use of the Windows API function ExitWindows(), FoxPro will not do a complete cleanup and can leave .TMP files in your TEMP subdirectory.

1. In a program, open the FOXTOOLS.FLL external library. To do this,

   use the SET LIBRARY TO command as follows to ensure that the
   program finds the FOXTOOLS.FLL library in the FoxPro directory:

      SET LIBRARY TO SYS(2004)+"FOXTOOLS.FLL" ADDITIVE

2. Register the Windows API functions that you would like to call. In

   this case, use the ExitWindows() API call:

      getout=REGFN("ExitWindows","II","I")

3. To completely quit Microsoft Windows and all applications running

   under Windows, issue the following command:

      =CALLFN(getout,0,0)

NOTE: In Windows 95, this procedure displays the Shut Down the Computer dialog box, then exits from Windows.
