asynchronous socket timeout

[sdlangers]

Hi All,

 

Anyone know how to set the timeout value for a client socket thats trying to asynchronously connect to a server.

 

I know this seems dumb since its connecting asynchronously, but i'd still like to shorten the timeout value.

 

For example :

 

client = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP)
' set timeout value
' client.timeout ????
' asynchronous connect        
client.BeginConnect(EP, AddressOf sockconnected, client)
       

 

Thanks

I don't believe so, only for sending and receiving data. I asked a friend, and he doesn't believe BSD sockets offer a way of doing this, he has unsuccessful in finding a way to do it with winsock and win32 either.

 

Your best bet is probably to use a timer and do it yourself.

Hi,

 

Thanks for your help.. ok, so if i use a timer.. how do i end the connection attempt after starting it asynchronously?.. i.e. would it not still try to fire the callback function whenever it does timeout?

 

Thanks again for your help - im new enough to sockets

I guess you could attempt to call the .Close method. It's not something I've ever had to do so I don't know. I guess if you closed the socket and disposed it, the callback wouldn't fire.

Long time in comming but here is a response

 

m_DataSocket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 60000);

m_DataSocket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, 60000);

 

This is more for people who are lookign for the answer now then to answer your question. I was looking and happend to find it in some example of FTP. Anyway, here it is.
