我们有了这两个强有力的类的支持就可以开始我们的编程工作了….

   1.用VC6++建立一个MFC基于对话框的工程:MicDemo;

   2.添加我们的两个类CSoundIn,CwaveFile;       

   3.当我们点击开始(Start)按钮的时候我们就要开始录音了…

         void CMicDemoDlg::OnStart()

        {

                m_btnStart.EnableWindow(FALSE);               

                if(theSoundCapture().__initMic())

                {

                      m_filePath.SetWindowText(_T("yangchen.wav."));        

                      theSoundCapture().__createOutputWaveFile(_T("yangchen.wav"));                    

                     if(!theSoundCapture().__openMic())

                      {

                        ::MessageBox(this->m_hWnd,_T("Can not open microphone!"), _T("Error"),MB_OK|MB_ICONERROR);

                         return;

                      }

                }

                m_btnStop.EnableWindow(TRUE);

              // 设置定时器是为了画波形用的     

                SetTimer(1, 200 /*start slow*/, NULL);

           }

    4.在定时器的回调函数中画波形.

           void CMicDemoDlg::OnTimer(UINT nIDEvent)

            {

                    if(nIDEvent == 1)

                   {          

                                static const int xCon = 13;

                                static const int yCon = 13;

                                static const int wCon = 623;

                                static const int hCon = 80;

                                CClientDC dc(this);

                                CBitmap   Bitmap;

                                CBitmap * pbmOld = NULL;                             

                                CDC     &n
