Solve the Problem of csocket and create socket errors of Vc in COM.

BecauseProgramCom is used, while Create fails when socket is used. The solution found on the internet is feasible and shared.

Add the following to the CPP file of the application class:

 

# DEFINE _ afxsockthreadstate afxgetmodulethreadstate ()

# DEFINE _ afx_sock_thread_state afx_module_thread_state

Bool chfccm2serverapp: initinstance ()
{

......

// -- Solve the Problem of create socket error in COM
_ Afx_sock_thread_state * pstate = _ afxsockthreadstate;
If (pstate-> m_pmapsockethandle = NULL)
Pstate-> m_pmapsockethandle = new cmapptrtoptr;
If (pstate-> m_pmapdeadsockets = NULL)
Pstate-> m_pmapdeadsockets = new cmapptrtoptr;
If (pstate-> m_plistsocketications ications = NULL)
Pstate-> m_plistsocketications ications = new cptrlist;

......

}

 

This is a bug on the Internet.
