承接专栏《MFC工控项目实例之十五定时刷新PC6325A模拟量输入》
验证选定的输入信号实时状态
在BoardTest.cpp文件中添加代码

void CBoardTest::OnButton2() 
{
	// TODO: Add your control notification handler code here
	isThreadBegin  = true;            //运行线程执行
     pThread = AfxBeginThread(My_TheradFunc,(LPVOID)this);
	 CString tempStr,tempStr1;
	int read;
	GetPrivateProfileString("输入信号","信号2",NULL,tempStr.GetBuffer(20),20,strFilePath);
     read=_ttoi(tempStr);
	 if (tempStr=="-1")
	 {
		SetDlgItemText(IDC_STATIC99,"输入信号2是 0");
	 }
	 else
	 {
	 tempStr1.Format("输入信号2是 %d ", b[read]);
	 SetDlgItemText(IDC_STATIC99, tempStr1);	 
	 }     
}
