VC6.0编写的一个大屏七段数码时钟程序纯代码绘制七段笔画

ID:920755 · 发表于 2022-5-4 08:10

VC6.0编写的一个大屏七段数码时钟，纯代码绘制七段笔画，使用定时函数读取系统时间，再以七段数码管的形式显示在屏幕上，字体颜色可变，背景颜色可调节。

部分程序如下：       //{{AFX_DATA(CLEDClockDlg)
      enum { IDD = IDD_LEDCLOCK_DIALOG };
      CDigitalClock m_clock;
      int             m_green;
      UINT       m_hour;
      UINT       m_minute;
      UINT       m_second;
      int             m_blue;
      int             m_red;
      int             m_shour;
      int             m_sminute;
      int             m_ssecond;

            }
      }

      // Set the icon for this dialog.  The framework does this automatically
      //  when the application's main window is not a dialog
