Okay I call Console.Read() twice. However when I come up on my second
Console.Read() ASCII character 10 is already on the console (that's a line
feed).
How do I clear out that line feed before I call Console.Read() again?

Steve,
Can you show the code where this is happening? Console.Read shouldn't
be feeding you the line character (I think).
If anything, why not use ReadLine?

char letter = (char)Console.R ead();
The first time through it is fine. The second time I can see in the
debbuger the a line feed is already in there.
I'm using Read instead of ReadLine becuase I just want a single char instead
of a string, and it seems like it would be simplier to do it this way.
Of course depending on what it takes to get around this issue I might change
my ind.

Steve,
You probably should do a readline. The reason for this is that when
dealing with console input, the buffer is not going to be filled until a
line is entered. Because of this, it's easier to just read the line and
process the string than it is to read character by character.
In .NET 2.0 however, there are ways of detecting when there is a
keypress, which might be of use to you.
Hope this helps.

I've got a very large C# forms app and now that its being used in

Hi,
I have two threads in my application, one that decodes audio to a

If I run them as two seperate processes I can pipe the output from one

output are obviously synchronous, so the decoding occurs at the rate at

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
