1、打开VC++6.0,点击“新建”按钮,点击MFC Appwizard,在工程名称一栏输入想要的工程名称,在位置一栏输入想保存的路径,然后点击确定:
2、打开对话框,在对话框上面添加控件如图所示:
3、为计时器添加count count2,ksorzt,ksorzt2,minute,second,minute2,second2几个成员变量如图,并在构造函数中初始化:
4、为对话框中的控件添加成员变量,如图所示:
5、在:OnInitDialog()中添加代码:(改变编辑框中的字体)
6、添加OnTimer()消息处理函数:并添加如下代码:void CJssDlg::OnTimer(UINT nIDEvent){ // TODO: Add your message handler code here and/or call defaultif(ksorzt) { if(count>0) { minute=count/60; second=count%60; CString str; str.Format("%d"":""%d",minute,second); m_strTime=str; UpdateData(false); --count; } else { m_strTime="时间到!"; UpdateData(false); } } if(ksorzt2) { if(count2>0) { minute2=count2/60; second2=count2%60; CString str2; str2.Format("%d"":""%d",minute2,second2); m_strTime2=str2; UpdateData(false); --count2; } else { m_strTime2="时间到!"; UpdateData(false); } } CDialog::OnTimer(nIDEvent);}
7、为正方和反方的开始和暂停按钮添加消息响应函数:void CJssDlg::OnButton1(){ // TODO: Add your control notification handler code here ksorzt=true; }void CJssDlg::OnButton2(){ // TODO: Add your control notification handler code here ksorzt=false; }void CJssDlg::OnButton3(){ // TODO: Add your control notification handler code here ksorzt2=true;}void CJssDlg::OnButton4(){ // TODO: Add your control notification handler code here ksorzt2=false;}其中button1和button2为正方的开始和暂停按钮,button3和button4为反方的开始和暂停按钮
8、为正方和反方的从新开始按钮添加消息相应函数:void CJssDlg::OnButton5(){ // TODO: Add your control notification handler code here ksorzt=false; count=600; m_strTime="10:0"; UpdateData(false); }void CJssDlg::OnButton6(){ // TODO: Add your control notification handler code here ksorzt2=false; count2=600; m_strTime2="10:0"; UpdateData(false);}
9、编译联接,运行。
