xuyueandClaude Opus 5.5 eedf1aa2fb 项目 7 情景控制:虚拟时钟、项目资源、Windows Media Player、TrackBar
- 虚拟时钟:实训台时钟面板可拨时间、1×/10×/60× 倍速、恢复真实时间;编译时把
  DateTime.Now / Today / UtcNow 改写成 SimClock;评分规则加 clock 步骤
- 项目资源(Properties.Resources):平台素材库(自绘开关图片、合成门铃声),"项目资源"对话框勾选,
  平台生成 Properties/Resources.Designer.cs;设计器图片框的"图片"属性可选资源;程序目录下的 Resources
  指向素材库;未添加资源时给中文提示
- Windows Media Player(AxWMPLib):设置 URL 自动播放、Ctlcontrols.play/stop,浏览器里播放声音,
  实训台加广播喇叭;编译时给窗体嵌空资源,OcxState 取到 null 不报错;图片和声音统一按内容缓存(blob)
- TrackBar:拖动、点轨道、方向键,先 ValueChanged 再 Scroll;设计器加"滑动条""媒体播放器"
- 评分规则加 value、media 检查;示例项目 7 任务 1–3(修正书上开关灯判断写反、漏填串口列表)
- 修正:Properties/ 下的资源类不当作窗体;带命名空间的 System.AppDomain.CurrentDomain.BaseDirectory 放行
- 测试:虚拟时钟、TrackBar、项目 7 示例评分、作业起点带资源类
