audio functions in Winmm.dll

24 Oct 2006 2:02 PM

ray well

i need to play (in a windows app) all or part of wav/mp3/midi files thru
software without a user interface. i also need to allow the user to choose
the midi instrument to play the midi files by filling a list box with
available instruments.

i would prefer not to have to install a windows media player, or directx or
any special installations on machines that will run it.

it looks to me i'm best off by using Winmm.dll functions. where can i find
documentation for Winmm.dll ??

i know nothing about the playing of audio files in software, is there any
place i can get any basic info on this?

it looks to me that my needs are simple, 1)to play all or parts of wav, mp3,
or midi files, 2) to select the midi instruments, and it shouldn't be rocket
science to do it. i would appreciate some help on finding documentation of
Winmm.dll functions, and some basic intro on this subject.

thanks for any help

Go to groups.google.com and search for "vb.net winmm.dll".

For all of the pinvoke declarations you'll need see:
