Re: unmanaged use of IAudioEndpointVolume::SetMasterVolumeLevel

VB6 is COM is VB6. I suggest you start with some elementary documentation on
VB6 to read up on what COM and VB6 are.

Mixer APIs will set Mixer properties and hence are local alterations. I said
use an MCI command.

Don't have Vista here, but since IAudioEndpointVolume is a COM
interface, can't you just set a reference to the object and code it
using normal VB6. Note Ixxx classes are actually interfaces - you'll
need an implemention.

I am a COM beginner, how is this done?

BTW, If all you want to do is change the system volume level, then
IAudioEndpointVolume is overkill. Just send an MCI command as you
would have done under previous Windows versions.

Are you sure?
With the method I use until now (MixerOpen...) in Vista it only changes
the volume level corresponding to my application, not the system wide
level.
