查了MSDN，知道了：
when isdialogmessage processes a message,it checks for keyboard message and converts them into selections for
the corresponding dialog box.
IsDialogMessage是检查对话框上的键盘消息的，我测试了一下：
在键盘上放置3个按钮，OK,BUTTON1，BUTTON2，缺省按钮是OK，三个按钮都有制表符TAB，运行的时候测试结果汇报如下：
当按下键盘上的TAB键焦点会在三个按钮之间进行切换，按下回车或者空格就会触发OK按钮（缺省按钮嘛）来关闭对话框。
When IsDialogMessage processes a message, it checks for keyboard messages and converts them into selections for the corresponding dialog box. For example, the TAB key, when pressed, selects the next control or group of controls, and the DOWN ARROW key, when pressed, selects the next control in a group.
哦，写在控件的消息处理程序中，我写在对话框中是因为MSDN中有句话是这么说的。
IsDialogMessage sends WM_GETDLGCODE messages to the dialog box procedure to determine which keys should be processed
经过测试确实是应该写在控件的窗口过程函数中。
我说一下IsDialogMessage的返回值情况你看对吗
