hi, currently working on an internet cafe software which will be in client/server structure.Client and server will communicate in both ways(customers give orders from clients and server controls computers) and I am planning to use TCP sockets. So am I on the right direction? or what would be the best way? thanks in advance

a fast and stable connection type and your valuable comments would be nice

There is various way to do this... whatever I think for data transportation you should try web service...

Thanks

to make it clear, my program will be used in one place.All clients and the server will be side by side. so why web service?

Well...TCP/IP socket is good for small transaction.... My point of view was the data transport mechanism.. you know HTTP over TCP/IP allow you to transfer data as xml format...which is much more reliable,secured.

to get the best reply I think I have to be more specific. Things that I am planning to handle with the server part of the program are:

(program will be used in LAN with 27 computers)
- switch on/of client computers
- open/close customer accounts(keep records of passed/elapsed times and charges them to account
- always live connection to see if the client is connected or not
- sending small files to clients
(I don't care about security at all)

TCP is usually fine

Could you please clarify... Why you are saying TCP is usually fine?

Thanks

Well how often do you use UDP? And other protocols (like DCCP, SCTP, RSVP and ECN) are extremely rare

The other protocol SCTP is not rare. In Telecom, for Sigtran, SCTP is used.

hi,
Could someone please translate this code to vb.net ?

static string str= "OKVALUES";
static string encode(string s)
{
 string strTest = "";
 for (int i = 0; i < s.Length; i++)
 {
   byte b = (byte)s[i];
   strTest += str[b >> 4];
   strTest += str[b & 0xf];
 }
 return strTest ;
}

When you get mad...THINK twice that the only advice

Shared str As String = "OKVALUES"
Private Shared Function encode(ByVal s As String) As String
     Dim strTest As String = ""
     For i As Integer = 0 To s.Length - 1
         Dim b As Byte = CByte(s(i))
         strTest += str(b >> 4)
         strTest += str(b And &Hf)
     Next
     Return strTest
 End Function

Dim b As Byte = CByte(s(i))
I think the above line will generate a compile error...like
'Char' values cannot be converted to 'Byte'.

Thanks

I agree.
Dim b As Integer = Microsoft.VisualBasic.AscW(s(i)) should solve that.
