Can anyone guide me for the problem below, thanks in advanced.

1) Why my function 'AutoDial' below never show up the 'Dial-up Connection' dialog box and always return 1?

FUNCTION AutoDial(piType)
DECLARE INTEGER InternetAutodial IN WININET.DLL INTEGER dwFlags, INTEGER dwReserved

piType = IIF(TYPE('piType')='N',IIF(BETWEEN(piType,1,2),piType,1),1)
liSuccess = InternetAutodial(piType,0)

RETURN liSuccess
ENDFUNC
