Follow up Marv: These tutorials are way, way beyond your skill level. You need
to stay with basic programming techniques like working with subs and functions
and basic arrays before you go beyond the most basic of applications. And,
Bill's series is far from a beginners level tutorial. Also, stay with one OS,
IDE and Language until you master these basic programming constructs. Finally,
you need to learn to use your Error Window so you can fix simple syntax errors,
learn how variables are scoped which was detailed in my tutorials and elsewhere
all over the net and then you might try doing a sample programming application.
You never learned how to do the basics and so you can not understand nor code
your own projects and flounder when anything you copy and paste, or just
ReType, does not work.
Later...

hi.
doing a audio programming project using low level wav technology.
getting errors.
and looked at the tutorial.
but cannot seem to see any thing wrong.
can you help.
not liking the size and saying it is not in the context.
can you help.
marvin from australia.
ps: will paste the code and the error messages below.
using c# express 2008.
ate void FillWaveBuffer()
{
byte[] b = new byte[size];
if (audioStream != null)
{
int pos = 0;
while (pos < size)
{
int toget = size - pos;
int got = audioStream.Read(b, pos, toget);
if (got < toget)
audioStream.Position = 0; // loop if the file ends
pos += got;
}
}
else
{
b[i] = 0;
}
System.Runtime.InteropServices.Marshal.Copy(b, 0, data, size);
}
private void btnLoad_Click(object sender, EventArgs e)
{
LoadSong();
}
private void FillWaveBuffer()
{
byte[] b = new byte[size];
if (audioStream != null)
{
int pos = 0;
while (pos < size)
{
int toget = size - pos;
int got = audioStream.Read(b, pos, toget);
if (got < toget)
audioStream.Position = 0; // loop if the file ends
pos += got;
}
}
else
{
b[i] = 0;
}
System.Runtime.InteropServices.Marshal.Copy(b, 0, data, size);
}

ps: how to fix this.
any help would be appreciative.
tried rewriting this function three times.
and it is to load the wav file.
what the application is it opens a open dialog box, and then you open the wav
and it plays.
then you have a menu and buttons to control, stop. pause, and play.
