采用两个多媒体定时器，一个0.1秒计时,另一个用来对模拟量信号采集每秒100次.。
1、在SEAL_PRESSUREDlg.h中添加代码

class CSEAL_PRESSUREDlg : public CDialog
{
public:
	CSEAL_PRESSUREDlg(CWnd* pParent = NULL);	// standard constructor
	．．．
    UINT timerID;//自己添加的定时器ID变量	
	void DestroyTimer();//自己声明的销毁定时器函数
	UINT CreateTimer();//自己声明的创建定时器函数
	void OnTimer_1(UINT nIDEvent_1);
    static void CALLBACK TimeProc(UINT uID, UINT uMsg, DWORD dwUser, DWORD dw1, DWORD dw2);//定时器回调函数
    int t_time;

	UINT timerID_2;//自己添加的定时器ID变量	
	void DestroyTimer_2();//自己声明的销毁定时器函数
	UINT CreateTimer_2();//自己声明的创建定时器函数
	void OnTimer_2(UINT nIDEvent_2);
    static void CALLBACK TimeProc_2(UINT uID, UINT uMsg, DWORD dwUser, DWORD dw1, DWORD dw2);//定时器回调函数
   double  t_time_2;
   ．．．
   ｝

２、在SEAL_PRESSUREDlg.cpp中添加代码

void CSEAL_PRESSUREDlg::OnTesStart() 
{
	if (m_isStop)
		{
			m_TES_START.SetIcon(IDI_TES_START); 
        m_TES_START.SetAlign(CButtonST::ST_ALIGN_VERT);
		((CButton *)GetDlgItem(IDC_TES_START))->SetWindowText(m_isStop ? "结束测试" : "开始测试");			
		DestroyTimer();
		DestroyTimer_2();
         m_isStop=0;
		}
		    else
			{ 
			 
        	t_time=0;
			t_time_2=0.0;
		    m_TES_START.SetIcon(IDI_TES_STOP); 
            m_TES_START.SetAlign(CButtonST::ST_ALIGN_VERT);
		   ((CButton *)GetDlgItem(IDC_TES_START))->SetWindowText(m_isStop ? "结束测试" : "开始测试");
		   //	CTime m_time; 		
		   //   m_time=CTime::GetCurrentTime();             //获取当前时间日期
           //   CString   m_strDateTime=m_time.Format(_T("%Y-%m-%d %H:%M:%S %A"));   //格式化日期时间
           //  CString   str=m_time.Format("%Y_%m_%d ");   //格式化日期时间
           //	theApp.time_name=theApp.typ_name+"\\"+str+"\\";         

	SYSTEMTIME SystemTime;
	::GetLocalTime(&SystemTime);
	CString str1="",Date="";
	str1.Format("%02d",SystemTime.wYear);
	Date = Date + str1;
	str1.Format("_%02d",SystemTime.wMonth);
	Date = Date + str1;
	str1.Format("_%02d",SystemTime.wDay);
	Date = Date + str1;
//	str1.Format("_%02d",SystemTime.wHour);
//	Date = Date + str1;
//	str.Format("_%02d",SystemTime.wMinute);
//	Date = Date + str1;
//	str.Format("_%02d",SystemTime.wSecond);
//	Date = Date + str1;     
   theApp.time_name=theApp.typ_name+Date+"\\";
   	if (!PathIsDirectory(theApp.time_name)) //目录不存在
					{ 
	                //	MessageBox("文件不存在");
	                    CreateDirectory(theApp.time_name, FALSE);//不存在则创建
						cre_data();
					}
                    else //目录存在
					{
                 //	MessageBox("文件存在");
					cre_data();
					}
   
   SetDlgItemText(IDC_STATIC99,theApp.time_name);

		   	CreateTimer();	  
	    	CreateTimer_2();	  
	        m_isStop=1;
			}
   

}
