i did not used WSAGetLastError bcoz select() is continusly returning
-1

Look at http://msdn.microsoft.com/en-us/library/ms740141(VS.85).aspx . It
says the following: "The select function returns the total number of socket
handles that are ready and contained in the fd_set structures, zero if the
time limit expired, or SOCKET_ERROR if an error occurred. If the return
value is SOCKET_ERROR, WSAGetLastError can be used to retrieve a specific
error code.". If I recall corretly, SOCKET_ERROR is exactly -1, so why don't
you want to get extended error information?

and if there is problem in select() then data should not be
received continusly

Documentation clearly states that if select(...) is successfull it should
return something not equal to -1. So I suggest you the following:

1. Read documentation with attention
2. Check return values of functions
3. If possible, post your code snipped here, we are not telepates, sorry.
