Problem/Error with Embedded Resources (Sound File)

[Vanessa]

Anyone know how to embed sound file to vb.net project, then play the sound
file?

I have searched the web for example... and download the example and when
run, it works perfectly.

But when i try to insert a sound file (.wav) to my project and set the Build
Action to "Embedded Resources". And then I use the same code as what I saw
in the example, but it gives me an error,

An unhandled exception of type 'System.NullReferenceException' occurred in
Application.exe
Additional information: Object reference not set to an instance of an
object.

When i debug, it prompt an error at the if statement, when my mouse move
over to Str, it's nothing. Anybody knows what's wrong or what i did wrong?
Dim strNameSpace As String =
System.Reflection.Assembly.GetExecutingAssembly(). GetName().Name.ToString()

Dim Str As Stream =
System.Reflection.Assembly.GetExecutingAssembly(). GetManifestResourceStream(
strNameSpace + "." + wav)

if Str.CanRead Then

Regards

I think your problem lies in the assignment to Str, specifically the string
"wav" that you're appending. You have:

Dim Str As Stream =
System.Reflection.Assembly.GetExecutingAssembly(). GetManifestResourceStream(
strNameSpace + "." + wav)

And it should be

Dim Str As Stream =
System.Reflection.Assembly.GetExecutingAssembly(). GetManifestResourceStream(
strNameSpace + ".FILENAME.wav")

Where "FILENAME" is the case-sensitive name of the file you embedded as a
resource.

It appears that you're trying to use a variable named wav, rather than the
string value "wav."

Hope that helps,

Please don't post to more than two or three groups at a
time.

Firstly strNameSpace doesn't neccesarily contain the
namespace of your resource.

Secondly, where's the filename of this resource?

removable face plate, the trunk-mounted Cd player, with 8 speakers
and remote contol."

I hate being stereotyped.
