Hi,
I'm new to C# and the whole server/client thing, as an exercise I've made a simple board game for two players, now I'd like to make it playable on the net which is obviously not a trivial task (for me anywayz). I was looking for SIMPLE tutorials or articles about creating a web servers and clients, but havnt found anything basic enough - I need an example of client and server passing very basic pieces of data (strings?) on simple events between them, but the articles I've seen deal with more complex project. A point in the right directon would be very appreciated, thanx.

Remoting is an easy way of getting data flowing between the server and the clients.
Take a look at MSDN http://msdn2.microsoft.com/en-us/library/ms973857.aspx[^] or CodeProject http://www.codeproject.com/csharp/dotnetremotingbasictutor.asp[^]
Try creating two custom objects that you use as communication channels.
Let the server expose it's serverchannel object through remoting, and when client contacts the server through the channel, it can register the client and set up a remoting connection back to the clientchannel object, which the client exposes through remoting aswell.
You can put appropriate communication and game methods in these channels aswell as events which you can monitor.

-- Modified --
If you choose to go for a remoting solution where both sides expose a marshalled (remoting) object, remember to have each side set up their own remoting servers before they try and contact the other side. Otherwise the attemt at setting up local remoting server will fail as the remoting proxy from the otherside blocks the local server from being set up correctly.

Thanx will try that tomorrow when I can have both my eyes looking in one direction  btw, gotta love your signature

sqlite[^] is very good it's 1 dll (well in its pure native form) and then 1 db file per user if thats the way you want it 
not sure how it'd handle that much data but it's worth a look.
You still use ado.net to "connect" to it but it local and file based rather than network based.

without importing from win32 dll-s
or how do I communicate with a device with C# build in classes.
Does C# has something like this ? classes for registering/unregistering a service, and communicating via IOCTL's
thank you

Use DeviceIoControl without using Win32?? Impossible. You have no choice but to import the function calls.
euacela wrote: how do I communicate with a device with C# build in classes.
That depends entirely on the device in question, but if it's not connected to a Serial Port, you don't. There are no classes native to the .NET Framework that deal with device communication, like USB, PCI, low level disk/volume work, ...
euacela wrote: classes for registering/unregistering a service
Yes, this is built into the .NET BCL. I believe it's the ServiceInstaller[^] class in the System.ServiceProcess namespace.
euacela wrote: communicating via IOCTL's
No, this is NOT in the .NET BCL.

As for movie, you will need DirectX as I guess but I'm not sure as I'm not experienced in that field

You can use excel object library to convert the generated file to excel native format
|
|
|
|

I dont know how to do that sorry Im still new with programming so I dont know alot can you maybe send me some code if its possible please. Thanks again

You can use that article to generate xml file and then convert it to xls using this piece of code:
<br />
private void savetoexcelformat(string currentpath, string pathtosave)<br />
{<br />
object missing = System.Reflection.Missing.Value;<br />
<br />
Excel.Application app = new Excel.Application();<br />
app.Visible = false;<br />
<br />
app.Workbooks.OpenXML(currentpath, missing,missing).SaveAs(pathtosave, Excel.XlFileFormat.xlWorkbookNormal, missing, missing,<br />
missing, missing, Excel.XlSaveAsAccessMode.xlNoChange, missing, missing, missing, missing, missing);<br />
app.Quit();<br />
<br />
}

The leave event occure when i push the tab button
What happen with me is when i put the first digit the leave event is called
this the code:
private void txtNewExpDate3_Leave(object sender, EventArgs e)
{
string val = this.txtNewExpDate3.Text;
if (this.txtNewExpDate3.TextLength.Equals(1))
this.txtNewExpDate3.Text = "0" + val;
}
and the MaxLength for the txtNewExpDate3 is 2
I do the same code is the same event in other textbox and it work properly.
Thanks in advance

Trap the key you are interested in and invoke the event handler for the button or menu item
