/*1、首先打开串口，然后开始点击“开始发送”，程序从容不迫SendData()开始，在其中分主数据的通讯：当前温度，
另外：加入有读参数表，有读单个参数，及写参数
2、读参数时，正常情况下,由ProcessArray()进行处理，不断的SetTimer()和KillTimer(),并SendData(),只有不正常时，才会由
OnTimer()来启动SendData()来保持不断的通讯。
3、使用了大量的GetDlgItem()用控件ID来获得控件的一些控制。
4、其中BOOL m_shortProcess是用来在前一数据处理未完成，后面的动作已发生时，来处理这段时间的动作。
后面发生动作时，让其为T，当数据处理完成时，让其为F。short即时间很短的意思
