1) From MSDN:
"On a blocking socket, the return value indicates success or failure of the connection attempt." (0=connected). For non-blocking sockets follow the link to MSDN.

2) You check the value returned by recv(). Read more here

3) what??

thx for you're reply. For the 3rd question, i was wondering if it was possible to send window message like WM_LBUTTONDOWN instead of data...

a window message is simply a DWORD (0x0???).
convert the DWORD to data and send it.
