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.

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.

If you go to http://www.gotdotnet.com/team/csharp, you'll find my implementation of Spacewar!, which uses UDP over sockets.
The source is included; look on the information page.

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  .

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?

Does Messenger have native support for .NET now?
The last time I looked it was still COM, or is this what you're having problems with?

You can log all messages to a file for debugging purposes

If you want, you can compile your application as a console application, and it will still work as a windows app (forms and all) but the console will always be displayed.
You can change the type from the Project's properties dialog.

Even better is to use the log4net framework. Allows you integrate logging into your application. See: http://sourceforge.net/projects/log4net/
This way you can enable logging for a particular part of your application without having to change any source or recompile. Just modify the configuration file.

I am trying to overload this method on a form and capture the WM_LBUTTONDOWN message. I am fairly new to C# and could someone guide me how to do it.
Thanks

Handle the MouseDown event
create a function like this
public class MyForm : System.Windows.Forms.Form {
protected override void OnMouseDown(MouseEventArgs e) {
if (e.Button == MouseButtons.Left)
MessageBox.Show(this, "You clicked the left button");
else
MessageBox.Show(this, "You clicked some other button");
}
}

Hello Friends,

Has anybody having any idea about this.
Thanks in advance.

Try using the MdiChildActivate instead for MDI child windows.

I'm new to C# and was looking for help on sending objects through sockets.
I have a program(which I got from this site) that sends bytes through a socket, it's a client/server chat program. I have written a class and made it Serializable and am trying to send instances of my class through the socket but haven't a clue how to actually serialize the object into bytes and send it through the socket.
Hope someone can help,
Paddy.

public byte[] GetObjectBytes(object o)
{
MemoryStream memstream = new MemoryStream();
IFormatter formatter = new BinaryFormatter();
formatter.Serialize(memstream, o);
memstream.Close();
return memstream.GetBuffer();
}
public object GetObjectFromBytes(byte [] bytes)
{
MemoryStream memstream = new MemoryStream(bytes);
IFormatter formatter = new BinaryFormatter();
object o = formatter.Deserialize(memstream);
memstream.Close();
return o;
}
I'm not a network guy, but I assume you just call the Write method on the NetworkStream object representing your socket, to send the byte array, then call the Read method on the other side to read back the byte array.
GetObjectBytes() will serialize the object and return the byte array which you can pass to Write, GetObjectFromBytes() will deserialize the byte array from the Read method.
HTH,
James
