A first chance exception of type 'System.InvalidOperationException' occurred in System.dll

I am programming in Visual Basic 2008, and I recorded a sound with "Adobe Sound Booth CS3", Sound Fordge, and Windows Sound Recorder Test.WAV or Test.MP3, and then imported it into my Resources in Visual Basic 2008. But every time I try to drag and drop it into the Audio section in the resources it places itself into files catagory, and the icon looks like it has no program associated with it. I have written this line of code several times before and have never had this problem with this.

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

My.Computer.Audio.Play(My.Resources.Test, AudioPlayMode.Background)

    End Sub
End Class

It gives me this error...

The wave header is corrupt.
A first chance exception of type 'System.InvalidOperationException' occurred in System.dll

Like it said, I've did programs using this line of code before, and even my other EXE programs run fine, I can even use an old sound file, and it works, but why not now...?

It runs in the back of my mind that I read somewhere that Microsoft can make changes to the Visual Basic 2008 Express Eddition without notifing the users of the IDE.

So what do I need to do...? This is really depressing, I am good at programming, but am still learning, and I really don't have all the answers all the time, thats probably why I'm new here.

I tried to ask this question in Yahoo Answers, but they seem to not be smart enough to answer my question properly... I haven't got no answers there, lets see if MSDN Forums can answer this question, I hope they can, Can You...?

Hi,

Following on from Programble suggestion just make sure that your not dragging an mp3 in and then playing it as a wav. It seems like such a silly suggestion "I not that stupid" but it's maybe just something that daft. If you do this sort of thing all the time then sometime you can have a head slap moment.

If that wasn't the problem then maybe the wave file has been corrupted. Try another wav file.

Also add a breakpoint to the line...
My.Computer.Audio.Play(My.Resources.Test, AudioPlayMode.Background)

And hold your mouse over My.Resources.Test and make sure it is the right type for the Play() method.

Does your computer play the WAV file ok?

Last suggestion is if you can upload a small project somewhere and let us download it. Thing is we could try it out on a new project and it all works perfectly. We could download the problem project and then that works then the problem might lie with your machine. Just difficult without more information.

I just tested it by adding a .mp3 file to my projects resources, renamed it Test, and Ran this code:

Public Class Form1  

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click  

        My.Computer.Audio.Play(My.Resources.Test, AudioPlayMode.Background)  

    End Sub 

End Class

I get the exact same error you get when trying to play the file. i.e.: "The wave header is corrupt." Noticed I used a .mp3 file.

Next I tried a .wav file, and it worked fine. The reason is because like Programble said...... My.Computer.Audio.Play uses .wav files! Not .mp3 files!

Finally to prove it for sure, instead of using My.Resources, I pointed the .Play method directly to .mp3 file on my harddrive, and ran it again. This time I get the error:

"The file located at C:\Users\me\Music\New Folder\Some.mp3 is not a valid wave file." See the end of the error message..... "NOT A VALID WAVE FILE"

It even tells you right here, that its for playing wave files: http://msdn.microsoft.com/en-us/library/cf1shcah.aspx

Furthermore. These files sitting in your project resources. If you look at them do they have the media player icon, or is it just a generic icon. If its a .wav file it will have the media player icon.

Compensating what I don't know yet, with what I do know now.

Do this. Right click your toolbox, and click on choose items. Click on the COM tab, and scroll down. Select the Windows Media Player. Now you have the real windows media player at your disposal with all the codecs you have installed.

Drag and drop the control on your form. Set its visible property to false, then you can do this:

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load  

        AxWindowsMediaPlayer1.URL = "C:\Users\me\Music\New Folder\adf.mp3" 

    End Sub

Is your audio file playable from Windows Media Player? Which is it, test.wav, or test.mp3? My.Computer.Audio cannot play MP3 files.

Why, would that matter...?

If I type the code, it should compile and not have to give it a second thought.

Why now...?

I did my computer over, wiped everything, today, the Testing.wav file shows up in audio section in resources, and shows its a valid WAV file and stays in the audio section in resources, but it still gives the message...

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I tried importing images and such on here, as examples, but, how would I go about uploading the exe or the project...?

It's strange, because older previously made WAV files, worked, and even MP3's worked as well, I don't understand why it gives this new error message, when I know before I could write this line of code, and it would run 100%, no problems, now even the audio file, "wav" file shows up in the audio section in resources, and vb2008 reconizes that its a "wav" file, ... yeah, I can play anything on here, but when it gets time to execute this command with the "wav" file in the resources it gives the error, Currupt wav header...

IDK...

I can't seem to figure this out, maybe re-download the Visual Studio 2008, and start over...?

But I don't see how that would change anything, since I'm running it right now...

I just tested it by adding a .mp3 file to my projects resources, renamed it Test, and Ran this code:

Public Class Form1  

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click  

        My.Computer.Audio.Play(My.Resources.Test, AudioPlayMode.Background)  

    End Sub 

End Class

Is it maybe an mp3 file that has a wav file extension?

There is a much better way to play mp3 files using WPF rather than Media Player. Don't have the code handy but I'm sure you'll find it.
