在编辑框中显示默认值

改变编辑框中的RGB值，是静态框中的颜色改变

2.进程的基本应用

进程（Process）是指应用程序在内存中的一次运行过程。

进程不完成任何事情。

一个进程至少包含一个线程。

进程和程序的区别：

进程是运行状态，程序是静止状态（磁盘上的二进制代码）；

一个进程对应一个程序，一个程序可以对应多个进程。

进程是操作系统分配资源的最小单位

进程的操作方法

CreateProcess()函数创建进程

ExitProcess()退出进程

TerminateProcess()终止进程

Wince中最多能运行65535个进程

点击“Process”按钮，调用开发板上的程序

点击后，出现程序
