窗口类型可以通过windowstype属性设置，有以下6种，main类型最常用:

Child——A window that is dependent on a main window and can only exist within the main (parent) window.
Main —— A standalone overlapped window that can be independent of all other windows.
MDI —— An MDI frame without a MicroHelp status bar.
MDIHelp —— An MDI frame with a MicroHelp status bar.
Popup—— A window that displays usually in response to an event within a window, but can exist outside of the window and, in some cases, after the window that opened it is closed.
Response—— A window that displays to obtain information from the user and cannot lose focus or be closed until the user responds.
