1.isxdigit();
2.MAXDWORD>>4
3.isdigit();
4.M_PI
5.MAX_PATH
6.SendMessage(hwnd,EM_LIMITTEXT,32000,0L)

谢谢
2。MAXDWORD向左移位4位
3。判断是不是十进制数
4。M_PI,圆周率?
5。Maximum length of full path
6。sends the specified message “EM_LIMITTEXT” to a window or windows. The function calls the window procedure for the specified window and does not return until the window procedure has processed the message.
7。get a message identifier for the FINDMSGSTRING registered message.
8。对消息参数进行处理
2.MAXDWORD>>4
表示MAXDWORD向右移位4位
