2.1 Server
2.2 Client
3 Example Sourcecode
3.1 Server
3.2 Client

1 First Steps

At the beginning, you always have to include this control into your application. You do this by pressing CTRL+T and then selecting "Microsoft Winsock Control 6.0". If you only have an older version of Winsock, don't mind. There shouldn't be any (important) differences.

Secondly, an instance of the Winsock control has to be created inside your main form; most simply by double-clicking the Winsock icon in the "Toolbox" panel.

These first two steps are equal for whatever network application you want to code. Now, you have to differentiate between the use of TCP and UDP, and, of course, between client and server applications. In this tutorial, I'll only discuss how to build a simple TCP client/server-application.

2 Basic TCP

The use of TCP is much more common than the use of UDP. The main reason for this is the fact that UDP does not at all care about what happens to the data it sends across the net, and whether it reaches its host and in which order. TCP, however, can always tell you the current state of connection and also sees after the data, ensuring safe transfer across the internet. Therefore, generally, I would recommend you to use TCP.

So be sure to have the "Protocol"-property set to "sckTCPProtocol".

2.1 Server

What our server does, is listen on a specified port for incoming connections. When someone (a client) tries to connect to your application, you receive an event and are able to allow or to refuse the connection attempt.

What we have to do first, is set the "LocalPort"-property to the port number, on which we want the server to listen. Port numbers can be any integer between 1 and 65.535. It is recommended to choose a number over 1.024. To be (almost) sure that your desired port isn't already in use, I recommend using really high numbers.

Now, the server has to be told to start listening. This is done by calling the "Listen"-procedure. Example code for a typical Form_Load() follows.
Important remark: "sock" is how I called the Winsock control, you can choose any name you like.

Private Sub Form_Load()
  sock.Protocol = sckTCPProtocol ' choose the TCP protocol
  sock.LocalPort = 50505 ' an example port number
  sock.Listen ' tell
Winsock to start listening
End Sub

The server also has to know what to do when somebody tries to connect. Therefore, we have to edit the "ConnectionRequest"-event. In this event's code you can do whatever you want, but if you want to allow the new connection, you HAVE to call the server's "Accept"-procedure.

Private Sub sock_ConnectionRequest(ByVal requestID As Long)
  If sock.State = sckListening Then ' if the socket is listening
    sock.Close ' reset its state to sckClosed
    sock.Accept requestID ' accept the client
  End If
End Sub

What are we doing here exactly? At first, we check the server's "State". Only if the socket is listening ("sckListening") we call "Accept" and the connection is established. Remember to pass "requestID" to this procedure.

Nice. But now we need to go on to data exchange. In order to explain this to you, we will write a most primitive program :] Both the server and the client will have two textboxes in their applications. One showing what we are typing, one showing what the other side is typing. As soon as you change the content of your side's textbox, the text is also updated on the other side.

Thus, I'll add a textbox called "txtMe" and one called "txtOther". As soon as our text gets changed, we will send the new string to the client:

Private Sub txtMe_Change()
  If sock.State = sckConnected Then ' if there is a connection
    sock.SendData txtMe.Text ' send data to the other side
  End If
End Sub

I guess you have already guessed what "sckConnected" might mean ;) Data transfer is done by "SendData", as you can see. The procedure does not expect data in a certain format, you can send strings, numbers, and whatever else you can think of.

It is good practice to check for an established connection before trying to send data, otherwise your program will be terminated with a cryptic error message.

This is what will happen if new data is received:

' insert this line into (General)
Dim strData As String ' string for received data

Private Sub sock_DataArrival(ByVal bytesTotal As Long)
sock.GetData strData ' load received data into strData
txtOther.Text = strData ' show new string
End Sub

(Note that you have to insert the strData-definition into the "(General)"-section.)

As soon as data arrives, the "DataArrival"-event is triggered. The only information we get is "bytesTotal", the number of bytes we've just received. In our case, we'll just ignore that parameter 8)

You may ask why I declared strData at the start of all code, in the (General)-section, although we do not have to declare variables in VB at all! Well, at first I must say that it is ALWAYS a good idea to declare ALL variables. Secondly, by doing this, VB knows what kind of data it should receive from the socket.

Loading the new data into strData is simply done by calling "GetData". No problems here, I hope.

So far, everything looks fine and should work. We'll only add some code for the event of a suddenly closed socket (e.g. when the client exits).

Private Sub sock_Close()

sock.Close ' has to be called
sock.Listen ' listen again
End Sub

The "Close"-event is called when the OTHER side disconnects. In this case, it is important to call "Close" in order to get the "State" back to "sckClosed". Otherwise it would be "sckClosing", and "Listen" would only result in an error.

Some other error trapping would be a good idea, too:

Private Sub sock_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
  MsgBox "Socket Error " & Number & ": " & Description
                                    ' show some "debug" info
  sock.Close ' close the erraneous connection
  sock.Listen ' listen again
End Sub

Now that's a long list of parameters coming along with this event which is triggered every time something isn't working the way it should. However, we'll only use "Number" and "Description". Having the "Number", you can browse through MSDN (http://msdn.microsoft.com), for example, in order to get rid of possible bugs in your program. "Description" even gives you a nice, more-or-less understandable summary of the error which just occured. Narf. :]

Compile and run the server. Watch it do nothing ;) - yet...

2.2 Client

Now, let's write the client application. Create a new project, and follow the "FIRST STEPS" from chapter 2 again.

The difference between the client and the server should be clear. While the server waits for anybody to connect from a (firstly) unknown adress, the client needs to know which hostname or IP-adress the server has. That's why we need two new textboxes into which the user has to enter two values: One for the server's adress and one for the port it's listening on. In my example code, I call those boxes "txtIP" and "txtPort". We'll also need a button for connecting and disconnecting which we will call "cmdCon" (of course, such a button could also be added to the server).

When the button is pressed, the following happens:

Private Sub cmdCon_Click()
  If sock.State = sckClosed Then ' if the socket is closed
    sock.RemoteHost = txtIP.Text ' set server adress
    sock.RemotePort = txtPort.Text ' set server port
    sock.Connect ' start connection attempt
  Else ' if the socket is open
    sock.Close ' close it (user disconnected)
  End If
End Sub

This code should be quite
self-explanatory.

One important notice, though: "RemoteHost" must not be mixed up with "RemoteHostIP". While "RemoteHost" has to be set before connecting and can either be a string holding a hostname (for example "localhost") or a string holding an IP-adress (for example "127.0.0.1"), "RemoteHostIP" is automatically set by Winsock as soon as a connection has been established. This is done both on the server and on the client side, and holds the other side's IP-adress.

(Thus, this code would be a nice "feature" to add to our server's "Connection_Request"-event: 'MsgBox "Connected with " & sock.RemoteHostIP'. In the listing at the end of this tutorial, I've inserted this line.)

But now, let's get back to the client. Here's a change to the "Close"-event code:

Private Sub sock_Close()
sock.Close ' has to be called
End Sub

In contrast to the server, the client does not have to "Listen" again, of course. The same is true for the "Error"-code:

Another change to the server is the total absence of "Form_Load" and "ConnectionRequest". The things happening in there were only neccessary for the server.

All in all, client and server are not very different. That's why it is very easy to integrate both the server and the client code into one single application, especially for such small programs.

3 Example Sourcecode

Here are the complete source-codes, ready for copy & paste. However, you'll have to insert the Winsock controls, textboxes and command buttons on your own:

Server:

Quote:

1 Winsock control "sock"
2 Textboxes "txtIP", "txtPort"

Client:

Quote:

1 Winsock control "sock"
1 Button "cmdCon"
4 Textboxes "txtIP", "txtMe", "txtOther", "txtPort"

3.1 Server

Dim strData As String ' string for received data

Private Sub Form_Load()
  sock.Protocol = sckTCPProtocol ' choose the TCP protocol
  sock.LocalPort = 50505 ' an example port number
  sock.Listen ' tell Winsock to start listening
End Sub

Private Sub sock_Close()
  sock.Close ' has to be called

sock.Listen ' listen again
End Sub

Private Sub sock_ConnectionRequest(ByVal requestID As Long)
  If sock.State = sckListening Then ' if the socket is listening
    sock.Close ' reset its state to sckClosed
    sock.Accept requestID ' accept the client
    MsgBox "Connected with " & sock.RemoteHostIP
                                    ' show who we are connected with
  End If
End Sub

Private Sub sock_DataArrival(ByVal bytesTotal As Long)
  sock.GetData strData ' load received data into strData
  txtOther.Text = strData ' show new string
End Sub

Private Sub sock_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
  MsgBox "Socket Error " & Number & ": " & Description
                                    ' show some "debug" info
  sock.Close ' close the erraneous connection
  sock.Listen ' listen again
End Sub

Private Sub txtMe_Change()
  If sock.State = sckConnected Then ' if there is a connection
    sock.SendData txtMe.Text ' send data to the other side
  End If
End Sub

3.2 Client

Dim strData As String ' string for received data

Private Sub cmdCon_Click()
  If sock.State = sckClosed Then ' if the socket is closed
    sock.RemoteHost = txtIP.Text ' set server adress
    sock.RemotePort = txtPort.Text ' set server port
    sock.Connect ' start connection attempt
  Else ' if the socket is open
    sock.Close ' close it
  End If
End Sub

Private Sub sock_Close()
  sock.Close ' has to be
called
End Sub

Private Sub sock_DataArrival(ByVal bytesTotal As Long)
  sock.GetData strData ' load received data into strData
  txtOther.Text = strData ' show new string
End Sub

Private Sub sock_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
  MsgBox "Socket Error " & Number & ": " & Description
                                    ' show some "debug" info
  sock.Close ' close the erraneous connection
End Sub

Private Sub txtMe_Change()
  If sock.State = sckConnected Then ' if there is a connection
    sock.SendData txtMe.Text ' send data to the other side
  End If
End Sub

tips on how to do multiple socket connections:

You must have multiple winsock controls, an array of controls if you are comfortable with.

client side: not interesting, this can be done with multiple copies of program running.

server side: you need one ear and multiple mouths, that is, one listening socket and array of talkers; in ear_ConnectionRequest do not close your ear, create a new mouth and mouth.Accept talking

Here is my entire code for a UDP talker and UDP listener in separate forms, using VBA in Access 2003. Text sent from the talker form is displayed in the text box of the listener form.

Server (Talker)-Form has the Winsock control named “UDPTalkerSocket” and a command button named “cmdSendUDP”

Dim MsgCnt As Integer

Private Sub cmdSendUDP_Click()
  ' setup the socket
  MsgCnt = MsgCnt + 1
  If UDPTalkerSocket.State = sckClosed Then ' if the socket is closed
    UDPTalkerSocket.Connect "localhost", 12345
  End If

  ' send!!
  UDPTalkerSocket.SendData "Testing UDP" & MsgCnt & vbCrLf
End Sub

------------------------------------------------------------

Client (Listener) )-Form has the Winsock control named “UDPListenerSocket” and a text box named “txtText1”

Private Sub Form_Load()
  UDPListenerSocket.LocalPort = 12345
  UDPListenerSocket.Bind
End Sub

Private Sub UDPListenerSocket_DataArrival(ByVal bytesTotal As Long)
  Dim s As String

  UDPListenerSocket.GetData s
  txtText1.SetFocus
  txtText1.Text = s
End Sub

It works just fine on one machine! In that case you've got interprocess communications, between two VB sessions. One session runs the client code, the second runs the server code. Just use the your machine name (or IP) in the client's IP text box.

the server is what receives messages and the client is what sends messages, so if you want to have bidirectional communication you need both client and server routines in your program.

VB is way under-rated by most professional/corporate programmers. For many corporate applications, using VB with socket programming can be remarkably more efficient than the more typical MVC web applications (Java/dotNET/Ruby/PHP) that is currently in favor.

For the person who client stay in the state of "connecting", I had the same problem, but it's not a problem, to check the state you have to get out of the function and check the state again.

A steam room is a wonderful way to entertain friends and family as well. With a steam shower you can relax with a glass of wine or a nice chilled beer and unwind to start off the weekend. Or you could soak in your freestanding bathtubs on a Sunday night to get rested and prepared for the busy week to come. Your steam room can also provide wonderful entertainment whenever you hold parties or small get-togethers.

Are you an pvc figure collector or do you only realize how popular they are? Well, the fact is that because they are so popular with both children and collectors alike, some people are earning a lovely living out of trading anime toys both on and off line. Earning money from your hobby is both fun and fairly easy, if you know what you are doing. It is certainly possible for you to turn a profit from them too.There are prerequisites to making money from any hobby and trading in anime figures is no exception. You have to really immerse yourself in the toys and know which ones are hard to buy and which ones are the most well-liked with enthusiasts. You can gain this knowledge by reading, but to be honest, if you do not already know it, you are probably not interested enough.If you are not au fait with resin kit, try applying these principles to what you are interested in. Anyway, getting back to anime. There are comics, books and films that you should be familiar with before you can have enough knowledge to begin trading. You need to know the characters and also their personalities.The easiest manner to begin is if you sell what you already have. If you have looked after Anime Pillow, they could be worth quite a bit of money otherwise they will attract a reduced price. This is not necessarily a difficulty.
