Is it possible to play a .wav file through Windows Media Player?

Hello, I am trying to create a game that needs to have more then 2 sounds play at one time. I want Windows Media Player to play the background sound on a loop that is not interuppted by the other sound which will play from a button. I have been reading tons of posts and none have worked. Do I need to use the Soundplayer? I do not know what to do. Please help me. Thanks!

When I want multiple sounds I've used the old standard, windows multimedia dll and the mciSendString interface.

If you want the sound to loop, I've found that if you specify the type as "mpegvideo" then the repeat option will work.
It doesn't matter if what you're actually playing is a wav file, or mpg file or midi file, etc. If you say the type is mpegvideo on the play command, it will play the file and be able to loop using the repeat option.

Here is some code I used to experiment with some aspects of mci audio a little over six years ago.
It was probably in response to someone wanting to fade between two background loops, so as they walked around outside one loop would be playing, and if they walked into a building, the outside loop would fade out as the inside building loop would fade in (and vice versa when leaving the building).

For the example, I just added a trackbar with its maximum value set to 1000.
When you moved the trackbar it would adjust the volume of the two sounds, increasing one as the trackbar value increased and the opposite for the other.
If you had the trackbar at either extreme you only heard one, and in the middle you would hear both.

I also had two buttons to just turn off or on the audio from one of the loops, just to test the option of silencing one of the tracks, but not stop it from continuing to play.

Now, I've just added another button (button4) to play a short firing sound wav file each time the button is pressed, as an example to support what you've described.

One thing that sometimes people don't do when first trying to use mciSendString is to seek back to the beginning of the sound file each time they request it to play, so it only "works" once.
You could close the sound and reopen it each time before you play it, but I think that is just extra overhead compared to just resetting the play position each time.

You won't need the cross fading and two songs looping simultaneously, but since the code is already here and working, I'll post it as is, and you will need to pull from it what you want.
I copied both sound files to the executable directory, and tried different ways of opening the file just for experimentation, so you'll see two different methods used to do the initial commands.

The button1 code only needs to be done once, and initially, so could be done in the form load event. I just put it in the first button because I usually do that when testing something out, i.e. 1. Open a new project, 2. Add a button, 3. Put test code in button click event, 4. Run and hit button to test.

Alright, thank you very much!

problem solved!
