承接专栏《MFC工控项目实例之十七添加手动测试界面》
用到PC6408板卡，根据板卡设置界面组合框选项设定的输入信号，通过读取文件中保存的键值，用线程的方式实时检测输入信号通断，这里只用启动、停止两个信号示例。
1、在Data_1.h文件中添加代码
CString COMB_Data_1[]={"启动","停止"};
int COMB_Data_Number_1;
unsigned char b_1[16];
2、在JogTest.h中添加代码
class CJogTest : public CDialog
{
// Construction
public:CJogTest(CWnd* pParent = NULL); // standard constructorCButtonST m_btnStart_1[16];CFont m_font;CWinThread* pThread_1; bool isThreadBegin_1 ; //线程退出/执行控制void My_Func_1();static UINT My_TheradFunc_1(LPVOID lparam);CString m_Path;
CString strFilePath;
int In_lamp[16];
...
protected:
unsigned short nAddr_1;// Generated message map functions//{{AFX_MSG(CJogTest)virtual BOOL OnInitDialog();afx_msg void OnRadio1();afx_msg void OnRadio2();virtual void OnOK();virtual void OnCancel();//}}AFX_MSGDECLARE_MESSAGE_MAP()
};
#endif // !defined(AFX_JOGTEST_H__7E13E123_5220_40F7_9ED7_862C1685F610__INCLUDED_)3、在JogTest.cpp中添加代码
CJogTest::CJogTest(CWnd* pParent /*=NULL*/): CDialog(CJogTest::IDD, pParent)
{m_font.CreateFont(-28,0,0,0,700,FALSE,FALSE,0,134,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,FF_SWISS,"楷体_GB2312");TCHAR exeFullPath[MAX_PATH];GetModuleFileName(NULL,exeFullPath,MAX_PATH);m_Path = exeFullPath;for(int i = m_Path.GetLength() - 1; i > 0 ; i --){if(m_Path.GetAt(i) == '\\')break;}SetCurrentDirectory(m_Path);m_Path = m_Path.Left(i);strFilePath= m_Path + "\\Test.ini";nAddr_1 = 0x100; //设置板卡基地址COMB_Data_Number_1=(sizeof(COMB_Data_1) / sizeof(COMB_Data_1[1]));}BOOL CJogTest::OnInitDialog()

}UINT CJogTest::My_TheradFunc_1(LPVOID lparam)//将窗口指针赋给无类型指针{CJogTest *dlg = (CJogTest*)lparam; //可以调用CBoardTest定义的类成员函数while (dlg->isThreadBegin_1){dlg->My_Func_1(); //线程要执行的函数(调用CTheradtDlg定义的类成员函数)}return 0;}void CJogTest::My_Func_1() //处理函数在这里写
{for(int i=0;i<2;i++){
In_lamp[i]=_ttoi(b_str_1[i]);
b_1[i]=DI6408Bit(nAddr_1,In_lamp[i]);if (b_1[i]){m_btnStart_1[i].SetIcon(IDI_ICON_LedOn);}else{m_btnStart_1[i].SetIcon(IDI_ICON_LedOff);}}Sleep(100);
}void CJogTest::OnRadio1()
{CString tempStr;//int n=b_1[1];
//str.Format("s%",n);
tempStr.Format("%s",b_1[1]);

{// TODO: Add your control notification handler code here}void CJogTest::OnOK()
{isThreadBegin_1 = false; //停止线程执行
KillTimer(1); Sleep(500);
EndDialog(IDD_DIALOG_SYS_TEST);CDialog::OnOK();
}void CJogTest::OnCancel()
{
isThreadBegin_1 = false; //停止线程执行
KillTimer(1); Sleep(500);
EndDialog(IDD_DIALOG_SYS_TEST);CDialog::OnCancel();
}
