Before you begin:
Determine that Simple MAPI is available by checking the [MAIL] section in the computer"s WIN.INI file for the MAPI entry. This entry will have a value of 1 if Simple MAPI is installed, or 0 if uninstalled:



*lcSection = "Windows"  && section name
lcSection = "Mail"  && section name

lcKeys = getKeysString (lcSection)

CREATE CURSOR csWinIni (keyname C(30), keyvalue C(200))

lcKey = ""
FOR ii=1 TO Len(lcKeys)
    ch = SUBSTR (lcKeys, ii,1)
    IF ch = Chr(0)
        lcValue = GetKeyValue(lcSection, lcKey)
        INSERT INTO csWinIni VALUES (lcKey, lcValue)
        lcKey = ""
    ELSE
        lcKey = lcKey + ch
    ENDIF
ENDFOR

SELECT csWinIni

FUNCTION  getKeysString (lcSection)
* returns all key names found in this section

    nSize = 1024
    lpReturnedString = Repli (Chr(0), nSize)

    lnResult = GetProfileString (lcSection, 0, "#empty#",;
        @lpReturnedString, nSize)
RETURN  Left(lpReturnedString, lnResult)

FUNCTION  GetKeyValue (lcSection, lcKey)
