How to stop a blocking thread from another function that start in other in MFC

ISSUE: In server client scenario it is mandatory to use thread where sever is listening on a particular port.
Now in click of stop button ,how to stop this running thread.


SOLUTION:

#include <Windows.h>

HANDLE m_Thread_handle;
CWinThread *cTh;
static UINT __cdecl StaticThreadFunc(LPVOID pParam);
UINT ThreadFunc();
Step 1. Declared these on header file.

Step 2. Starting the thread from a function or button click ---


void CServerDlg::OnBnClickedStart()
{
    // TODO: Add your control notification handler code here

    cTh = AfxBeginThread(
    StaticThreadFunc,
    this);
    m_Thread_handle = cTh->m_hThread;
}
Step 3. Thread initialization function --

 UINT __cdecl CServerDlg::StaticThreadFunc(LPVOID pParam)
{
    CServerDlg *pYourClass = reinterpret_cast<CServerDlg*>(pParam);
    UINT retCode = pYourClass->ThreadFunc();

    return retCode;
}
Step 4. Work processing function for thread --

UINT CServerDlg::ThreadFunc()
{
    // Do your thing, this thread now has access to all the classes member variables
    CString txtname;
    GetDlgItemText(IDC_EDIT1, txtname);
    int iPort = _wtoi( txtname.GetString() );
    m_pServer = new ServerManager(this);
    m_pServer->StartListening(iPort);
             // while loop on start listening that are blocking call
    return 0;
}
Step 5. Now to close the thread from clicking stop button ---

void CServerDlg::OnBnClickedStop()
{
    // TODO: Add your control notification handler code here
    CloseHandle(m_Thread_handle);
    delete m_pServer;
}
