If i simply give like this, it's showing error as "cannot convert parameter 1 from const char to LPCWSTR",so i typecasted it as,

LoadLibrary(_T("library.dll"))

or

LoadLibrary((LPCWSTR)"library.dll"))

LoadLibrary((LPCWSTR)"library.dll"))

if i give like this it is not taking or recognizing the library gives error as No such lib found.

I accept the incoming connection by creating a new socket and calling its accept member......In some cases, 1 out of 5-6 test, I can't accept any new clients

You call Accept() on the listening socket instance and provides a reference to the new socket as argument, right?

CClientSocket* pNewSocket = new CClientSocket(this);	
if(!pNewSocket)
{
	//
	//	Error trying to create a client socket
	//
	WriteError(ecNotEnoughMemory, "cannot_create_new_socket", "AcceptNewClient");
	return;
}

if(m_pListenSocket->Accept(*pNewSocket))
{
	...
}

Yes, I do it like you mentioned.

Could it be that the message handling pump is 'broken'.

Roger Stoltz wrote:

What do you mean by "broken"?
Every thread that creates a socket has to be a UI-thread, i.e. it has got to have a message pump. This means you must have a CWinThread derivative where the socket is a member of the class.
If you create sockets in worker threads that don't have message pumps, Chaos and Mayhem will follow.
