[WTL] 窗体Style的含义

比较有用的设置：
(1)
WS_POPUP：弹出式窗体，没有标题栏！
WS_BORDER：细的黑边框
WS_OVERLAPPED：一般的有标题栏的窗体，见多了。
WS_CHILD：子窗体，一般用于Frame里面的窗体
(2)
WS_CAPTION：标题栏
WS_SYSMENU：系统菜单(只有设置后才有最小化、最大化、关闭)
WS_MINIMIZEBOX ：最小化按钮
WS_MAXIMIZEBOX：最大化按钮
WS_MINIMIZE：启动时最小化
WS_MAXIMIZE：启动时最大化

(3)
WS_EX_TOOLWINDOW：不在任务栏里显示条目
WS_EX_WINDOWEDGE：
WS_EX_CLIENTEDGE：具有凹陷感
