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.
