The problem is the unecessary & to take the address of the CString object. If you only need read access to the string data in a CString object, you can use the (LPCTSTR) conversion operator to get a pointer to the buffer. Then you'll have to use a cast, because NetMessageBufferSend() expects an LPBYTE rather than an LPCTSTR. That is, change
(LPBYTE)&buffer,
to
(LPBYTE)(LPCTSTR) buffer,

Casting away the constness of the LPCTSTR doesn't matter in this case, since NetMessageBufferSend () is only going to read the buffer.
