| | | Mixer API demo. A clone of the Windows Mixer(sndvol32.exe). Volume/Balance/Mute controls fully responsive to external changes via callbacks from winmm.dll.
The Mixer API causes problems for VB coders everywhere. The tangled web Microsoft created turns what should be simple into a nightmare. In this demo I try to untangle some of this mess by cloning the Windows Mixer(sndvol32.exe) as an example of how to write your own Volume/Balance/Mute controls. As an App it's pretty useless as sndvol32.exe exists on all Windows platforms, but for all those Audio/MP3 coders out there, it should make life a little easier.
Update:
As requested an "Administrator" version(Included as a separate zip)
Added:
1. The ability to lock Volume,Balance and Mute for each control
2. Save settings as presets
3. Run hidden - simple code - not 100% hidden, but good enough to keep
the average user out.
The save settings demonstrates writing settings to a binary file, something not often seen here on PSC.
What it will do: If a control is locked, not even sndvol32.exe can make changes. The given control
cannot be altered.
Security is low - I'll leave it up to you to bump up the security level.
What it wont do: If a 3rd party App communicates directly with the soundcard(WinAmp for example)
it can effect changes.
Screenshot shows "Administrator" version

Thank you MrBobo, Great example code and very helpful as usual. Maybe it's time for you to become SirBobo? I certainly appreciate your generosity in sharing so many great examples and programs. *****

Interesting Code.
--Can you make an enhanced version that can 'SAVE' and 'RESTORE' slider settings for each group? And, how about a routine to 'HOLD' them?
--The reason I ask is because I am tired of people using my computer, websites with 'MIDI/WAV', Games and other programs that reset my volume.
--It would be worth another 5

Excellent as usual.
You always seem to submit the most comprehensive and useful examples on PSC.
My soundcard has a video input which does not show up on any of the code examples here. any ideas how to access it?

Really great and useful code! If you need ideas for improvement, i could very much use an example of programming the input selector of the sound card. (The recording control of sndvol32.exe)

I'm a VB Newbie. I've been playing with this code for a few days, and I can't figure out how to add input mixer controls to Bobo's mixer. All of my sound is thru a Yamaha mixer inc microphone. It goes into the PC via Line in. I want to write a util that locks the recording source (MUX) to Line In. All voice chat programs etc change this to Mic. Can anyone point me in the right direction?

Can you mute right channel and mix Left channel then output to 2 speaker as Mono sound. I'want to remove vocal from Karaoke VCD that I'm play with my PC.

Bobo,
i don't see how you made anything more clearer, or easier to understand...
you can't even see the way the code works.

Sorry to disappoint you MrNoName. On looking back over the code you may have a point - I could have perhaps added more comments. On the other hand it uses much less code than other examples which have similar capabilities, which by itself makes the process easier to understand. Perhaps you could make a more instructive example for the rest of us to learn from.

Help!
I upgraded my computer to 256M ram and now the program Hangs? Hangs until "99% Resources Used Please Shut Down Some Programs" Is there some memory leak? The Mixer window draws the outline, but the BoBoMixer objects do not appear (at first)... but the program doesn't function now?
