一直觉得SilkTest的ChildWin不好理解，今天大致看了一下，其实它和DialogBox每啥区别，也是一种window类型。帮助里面说，典型的ChildWin就是文档窗口。在Windows上， ChildWin是MDI (多文档接口multi-document interface)子窗口，可以在main window中被最大化，最小化，调整大小的窗口，一般地,childwin有一个系统菜单。
下面是一个打开silktest onlinehelp define window的例子，原来的 define window是DialogBox,现在把它改成childwin一样能够被silktest识别出来。（具体区别请对照上一篇 SilkTest天龙八部系列3-动态父窗口）
