How can I change the volume for both Win 9x & NT. I want to increase and decrease the volume. Is it possible to change the windows volume and / or the wave volume? It must also change the sliders in the Volume Control window. Thanx in advance.

you can use

dwVolume set like:
Left + Right = $FFFFFFFF
Left  = $0000FFFF
Right = $FFFF0000
no sound = $00000000

medium sound example:


WaveOutGetVolume gets teh current volume.
