ByVal maxNumberOfPeers As Integer _
The IP address of the host computer (the SCP's address).
The port number of the host computer (the SCP's port).
If hostAddress is an empty string or a null reference (Nothing in VB), the IP address will be the local computer's address.
If hostAddress is "*", the IP address will be all of the local computer's addresses. This is useful if the local computer has more than one network interface and address.
If hostPort is 0, the port number will be the number of the first available port.
The maxNumberOfPeers parameter is the value passed to the WinSock listen() function for the backlog parameter that limits the size of the queue for waiting connections. As an example, suppose that the value is set to 3 and that 4 people try to connect at exactly the same time. In such a case, all 4 will be rejected because the connection backlog queue is full. But if one of the connections has been accepted by the time the 4th is made, then all will work.
To determine how many clients are connected and impose a limit on the number of connections, perform the following steps:
To use your computer as an SCP, you must first create a DicomNet object. Then call Listen to listen for incoming connection requests.
For an example, refer to SendAssociateRequest.
