hi all,

I have a dll for my app's communication purposes. The dll uses CSocket
for communication. The application is in C# and dll is written in
managed c++.
On calling 'Connect' mthd of dll, a socket is created and connected to
server. Everything works fine till this. My aim is to reconnect
automatically whenever connection fails.
When connection is lost, CSocket raises OnClose event. This will notify
dll consumer tht connection is lost. There i starts a thread (Delegate)
and calls dll's Connect mthd again. This time socket creation fails
giving error 10035 'A required resource is unavailable'. The connect
mthd in DLL goes like this;

Try using the CSocket::Create function instead of CSocket::Socket. I'm
not sure what CSocket::Socket is for (it's new), but it says in the docs
that if you use it you also have to call CSocket::Bind, which you are not
doing.

If they are anything like the WSA and BSD calls then you would only need to
call bind for a server; client sockets receive a port dynamically allocated
by the network stack.
