Define two macro
# define _ConsumeTmStart dwords dwStartTick=GetTickCount () ();
# define _ConsumeTmEnd () TRACE (_T (" consume tick=% u \ n "), the GetTickCount () - dwStartTick);
When use to insert the two macro

When the connection is to check whether have connection, if you have connected directly returns TRUE, open or shut down first, and then
