系统小闹钟V1.0 C#程序小例

2013年08月29日 ⁄ 综合 ⁄ 共 7373字 ⁄ 字号 评论关闭

因为发现自己经常计划好了做些什么事儿,到点儿了有时候经常忘,于是自己用C#写了一个系统闹钟程序。

目前是V1.0版本 后期还会继续优化。。

程序实例可在本网资源中下载http://download.csdn.net/detail/tskyfree/4239406

软件名称:Clock v1.0

软件功能:设定闹钟

具体详解:
                      左侧显示系统当前日期

                      显示系统当前时间:图形化表盘+数字化显示

                      区间模式:
                                 设定任务名称
                                 设定任务起止时间
                                 显示当前任务状态
                                 填写合理时间并设定,任务中可随时终止或退出程序

                     计时模式:
                                 设定任务名称
                                 设定距任务执行的倒计时时间
                                 显示当前任务状态
                                 填写合理时间并设定,任务中可随时终止或退出程序

                     窗体最小化后不显示在任务栏中,在右下侧托盘区显示小图标,点击小图标可还原  窗体

                     任务计时到达终止条件时:自动弹出提示,窗体置顶

                     支持快捷键操作 Alt+相应快捷键
