I am trying to cycle through a particular file, preferably 5 bytes at a time, I have this code so far but it doesn't work correctly. Any ideas.

        string a;
        byte b = new Byte();
        ArrayList arrText = new ArrayList();
        a = "test.txt";

StreamReader objReader = new StreamReader(a);

while (b != null)
{
    b = (byte)objReader.Read();
    arrText.Add(b);
}
objReader.Close();

Any help? Thanks

StreamReader.Read Method reads the next character from the input stream and advances the character position by one character.

That's from MSDN

In .NET a character is not a byte but two bytes. Maybe that's the problem.

Ok, here is the unequivocal question, how do I cycle through bytes of a file? Thanks for your response Nish.

Use the BinaryReader class and call ReadByte Smile | :)

IMHO you should use ReadBytes instead of ReadByte, then you can read all 5 at once instead of 1 at a time.

While that's true, internally they'd both be using 128 byte or higher read ahead buffers I think. But then you are very much correct of course Smile | :)

Help with peer to peer communication

First of all am I in the right Forum?

I'm thinking of making a simple peer to peer game in C# using remoting and WinForms. I would most likely need to send simple things like X,Y coordinates to each peer. My question is how should I accomplish this? The only method I can think of is storing each player's coordinates in a simple file then have each peer read each others coordinate file. This approach I beleive would operate poorly and would be extremely slow. I know there must be another way, does anyone here know how other games communicate or how I might go about doing this? Thanks for your time. Smile | :)

You could make a server module that people would sign into and have it control the sessions. This would be like what Unreal Tournement uses (I belive). Once the server is running on a computer, then the others could sign in and use other features such as finding players to play with, watching games already in progress, or replacing someone else in a running game. It seems more sensible to have a host in charge of communications which could be placed on another computer if the load is heavy so as not to slow any one down who is playing.

File I/O In C#

How can I specify app.Path as I do in VB6? I am trying to point to a .txt file that I have included in the folder of the application. Any suggestions?

P.S. - While I am at it, is there any specific way to do a Debug.Print? We used to have an immediate window in VB6 that allowed for this which was great for testing purposes. Thanks.

System.Windows.Forms.Application.ExecutablePath tells you where the executable is located that started the application. You can also use the StartupPath property, they both appear to do the same thing.

System.Diagnostics.Debug class has lots of methods for you to use; there is also the System.Diagnostics.Trace class which I use more often for no justifiable reason Poke tongue | ;-P

Has anyone played with the Microsoft Messenger API in C#? For some reason I cannot get it to sink and event (assign a delegate).

I didn't even know that they had one. What all can it do? And where can I get it from?

It is COM but here is the link:

Supposed to be able to do quite a bit. Wanted to play with it but seems to blow when I try to set a delegate.
