SUMMARY
=======

The Microsoft Knowledge Base article Q130578, "How to Customize the Visual
FoxPro Environment" describes how to echo the Visual FoxPro environment settings
by opening the Options dialog box from the Tools menu, holding the SHIFT key and
clicking OK. However, this method does not show all of the Options settings,
such as the setting for Asynchronous execution under the Remote Data tab. This
article shows how to get all of the settings for Visual FoxPro that are listed
in the registry.

MORE INFORMATION
================

1. In order for values to display, you must first save the settings to the
  registry. This task can be accomplished by selecting Options from the Tools
  menu. Click the Set as Default button, and then click OK to close the dialog
  box.

2. Save the following code and run it with the syntax DO <program name>
  WITH <file name in which to save settings>. For example, if the program
  file were saved to Readsettings.prg, run the program by typing the following
  in the Command window to save the settings to a text file called
  MySettings.Txt: DO READSETTINGS.PRG WITH "MySettings.Txt". After the program
  runs, it displays an edit window that shows the current settings:

        *-- Code begins here.
        PARAMETER lsOutput

        *-- Defines from Winreg.h

        #define KEY_QUERY_VALUE      0x0001
        #define HKEY_CURRENT_USER    0x80000001

        lnKeyHandle = 0
        liValue = 0
        lpszValue = SPACE(255)
        lpcchValue = 255
        lpdwType = SPACE(255)
        lpbData=SPACE(255)
        lpcbData=255

        DECLARE RegOpenKeyEx IN WIN32API INTEGER, STRING, INTEGER, ;
          INTEGER, INTEGER @nKeyHandle

        DECLARE RegEnumValue IN WIN32API INTEGER lnKeyHandle, INTEGER ;
         liValue;
         STRING @lpszValue, INTEGER @lpcchValue, INTEGER, STRING @lpdwType, ;
         STRING @lpbData, INTEGER @lpcbData

        *-- Get a handle for the Visual FoxPro Options key.
        lnResult=RegOpenKeyEx(;
          HKEY_CURRENT_USER, "Software\Microsoft\VisualFoxPro\6.0\Options", ;
          0, KEY_QUERY_VALUE, @LnKeyHandle)

        *-- Get a file handle for output file.
        IF FILE(lsOutput)
           ERASE(lsOutput)
        ENDIF
        lhFile = FCREATE(lsOutput)
        lnReturn = .T.

        DO WHILE lnReturn = .T.

           *-- Clear the buffers through each loop.
           lpszValue  = SPACE(255)
           lpcchValue = 255
           lpdwType   = SPACE(255)
           lpbData    = SPACE(255)
           lpcbData   = 255

           *-- Walk through the values for the key.
        lnReturn=RegEnumValue(lnKeyHandle,liValue,@lpszValue,@lpcchValue,0,;
          @lpdwType,@lpbData,@lpcbData)

          *-- Quit when we start getting empty strings.
          IF LEN(ALLTRIM(lpbData)) = 0 AND LEN(ALLTRIM(lpszValue)) = 0
             lnReturn = .F.
             LOOP
          ENDIF

          *-- Strip anything after the first null character.
          lpszValue = SUBSTR(lpszValue, 1, AT(CHR(0),lpszValue) - 1)
          lpbData = SUBSTR(lpbData, 1, AT(CHR(0),lpbData) - 1)

          *-- Write it out to the file.
          lFresult=FPUTS(lhFile,ALLTRIM(lpszValue) + " " + ALLTRIM(lpbData))

          *-- Increment the value index to move to the next value.
          liValue = liValue + 1
        ENDDO

        *-- Close our file handle and open an edit window.
        FCLOSE(lhFile)
        MODIFY FILE (lsOutput)
        *-- Code ends here.
