At this point you could do some fancy string manipulation to extract message information, however this program doesn’t. sckSuccess 40017 Successful. It passes messages through the server which echoes said messages to the other clients. HelpContext Help file context.

sckMsgTooBig 10040 The datagram is too large to fit into the buffer and is truncated. The client computer does not directly talk to the other client computers. While there is a detailed error “object” (similar to a control but with no visual interface), it is beyond the scope of this tutorial to delve into that object. http://stackoverflow.com/questions/786431/why-does-my-winsock-control-not-function-correctly-in-vb6-within-the-context-of Click here it's easy and free.

The program works fine when I test it on my local machine but when I try to connect to a remote machine I end up with a run time error 40006. However, several users have been reporting unexpected disconnects that only apply to my app - all other TCP programs remain connected, so it’s obviously not an issue with their connection.

  • Basically though what I was trying to say is most errors in most cases have to be considered serious enough to warrant a disconnect.
  • I'm still bothered by that Winsock.Close in the server.
  • Now, Winsock1(0) can keep listening while you Load Winsock1(n) to .Accept a ConnectionRequest.

It will take a few seconds for the dialog box to load 3. Visit Website If you program using the Object Oriented Paradigm, you may be familiar with two of these words. sckAddressInUse 10048 Address in use. When the control is in this state, you can safely invoke the listen method or make changes to ports, and IPs sckOpen 1 Open.

SERVER/CLIENT:          FORM:                      This program will use a form that looks similar to the following: The user will either click the Host or Connect button, at which point in time check over here This allows you to route all error to a common spot. However this is very tedious to enact on a much larger scale, especially because sometimes the program will be sending non-user drive events. Code: Private Sub Form_Load() Win.LocalPort = 4999 Win.Listen End Sub Private Sub Command1_Click() Win.Close Win.Listen End Sub Private Sub Win_ConnectionRequest(ByVal requestID As Long) Win.Close Win.Accept requestID End Sub Private Sub Win_DataArrival(ByVal

Its very simple and the app can work with mutisocket....

This is usually due to a program bug, like trying to treat the Winsock control as a synchronous socket and just pumping data out madly via repeated SendData calls without waiting Understanding these terms will allow you to quickly learn any new control Properties are the most basic function of an ActiveX Control (“control”). It then sends a brief message to the client so the client knows the server is ready. : What does the "call" do?

The following code demonstrates how a client can manually track down a time-out error during connection:     wskTCP.Connect IP, CLng(txtPort.Text) ‘Attempt to connect         lTime = 0 ‘Initialize the counter

NOTE: You may have heard of other connection models. sckGetNotSupported 394 The property can't be read.

To set the value of a property, you do the following:      Control.property = “Value to give the control” ‘Property is assigned the string             To get the value Finally, if for some reason you need to turn all error checking off you can do the following:      On Error Goto 0 The code tells the computer to not go sckSetNotSupported 383 The property is read-only. weblink Reply With Quote Jul 7th, 2007,03:45 PM #2 DigiRev View Profile View Forum Posts "Digital Revolution" Join Date Mar 2005 Posts 4,471 Re: winsock error handler You can't use Listen, Connect,

When you come back to your code you may have forgotten typical errors that occurred and will be left having to put in very generic code.
