Beep's de distinta frecuencia en win 98 usando VB6

[Eternal Idol]

No, esto dice en la MSDN:

Beep

The Beep function generates simple tones on the speaker. The function is synchronous; it does not return control to its caller until the sound finishes.


BOOL Beep(
DWORD dwFreq,
DWORD dwDuration
);

Parameters
dwFreq
[in] Frequency of the sound, in hertz. This parameter must be in the range 37 through 32,767 (0x25 through 0x7FFF).
Windows Me/98/95: The Beep function ignores this parameter.
dwDuration
[in] Duration of the sound, in milliseconds.
Windows Me/98/95: The Beep function ignores this parameter

Por lo tanto la funcion Beep, no sirve en 9x para lo que queres hacer.
