I am learning about threading and multithreading..so i just created a small application in which i will update the progressbar and a static text using threading.I vl get two inputs from the user, start and end values for how long the loop should rotate.I have 2threads in my application.

Thread1- to update the progressbar(according to the loop) the static text which will show the count(loop count). Thread2 - to update the another static text which will just diplay a name

Basically if the user clicks start, the progressbar steps up and at the same time filecount and the name are displayed parallely. There's is another operation where if the user clicks pause it(thread) has to suspend until the user clicks resume. The problem is,the above will not work(will not suspend and resume) for both thread..but works for a singlw thread. Please check the code to get an idea and reply me what can done!

on button click start

void CThreadingEx3Dlg::OnBnClickedStart()
{
    m_ProgressBar.SetRange(start,end);
    myThread1 = AfxBeginThread((AFX_THREADPROC)MyThreadFunction1,this);
    myThread2 = AfxBeginThread((AFX_THREADPROC)MyThreadFunction2,this);
}

thread1

UINT MyThreadFunction1(LPARAM lparam)
{
    CThreadingEx3Dlg* pthis = (CThreadingEx3Dlg*)lparam;
    for(int intvalue =pthis->start;intvalue<=pthis->end; ++intvalue)
    {
        pthis->SendMessage(WM_MY_THREAD_MESSAGE1,intvalue);
    }
    return 0;
}

thread1 function

LRESULT CThreadingEx3Dlg::OnThreadMessage1(WPARAM wparam,LPARAM lparam)
{
    int nProgress= (int)wparam;
     m_ProgressBar.SetPos(nProgress);
       CString strStatus;
    strStatus.Format(L"Thread1:Processing item: %d", nProgress);
        m_Static.SetWindowText(strStatus);
    Sleep(100);
    return 0;
}

thread2

UINT MyThreadFunction2(LPARAM  lparam)
{
    CThreadingEx3Dlg* pthis = (CThreadingEx3Dlg*)lparam;
    for(int i =pthis->start;i<=pthis->end;i++)
    {
        pthis->SendMessage(WM_MY_THREAD_MESSAGE2,i);
    }
    return 0;
}

thread2 function

LRESULT CThreadingEx3Dlg::OnThreadMessage2(WPARAM wparam,LPARAM lparam)
{
        m_Static1.GetDlgItem(IDC_STATIC6);
        m_Static1.SetWindowTextW(L"Thread2 Running");
        Sleep(100);
        m_Static1.SetWindowTextW(L"");
        Sleep(100);
        return TRUE;

}

void CThreadingEx3Dlg::OnBnClickedPause()
{
    // TODO: Add your control notification handler code here
    if(!m_Track)
    {
        m_Track = TRUE;
        GetDlgItem(IDCANCEL)->SetWindowTextW(L"Resume");
        myThread1->SuspendThread();
        WaitForSingleObject(myThread1->m_hThread,INFINITE);
        myThread2->SuspendThread();
        m_Static.SetWindowTextW(L"Paused..");

    }
    else
    {
        m_Track = FALSE;
        GetDlgItem(IDCANCEL)->SetWindowTextW(L"Pause");
        myThread1->ResumeThread();
        myThread2->ResumeThread();

        /*myEventHandler.SetEvent();
        WaitForSingleObject(myThread1->m_hThread,INFINITE);*/
    }
}
