WM 普通窗口消息

Range Meaning
0 through WM_USER - 1 Messages reserved for use by Windows. // Windows系统消息
WM_USER through 0x7FFF Integer messages for use by private window classes. // 私有消息
0x8000 through 0xBFFF Messages reserved for future use by Windows. // 未来的Windows消息
0xC000 through 0xFFFF String messages for use by applications. // 应用程序的字符串消息
Greater than 0xFFFF Reserved by Windows for future use. // 未来的Windows消息

Message numbers in the second range (WM_USER through 0x7FFF) can be defined and used by an application to send messages within a private window class. These values cannot be used to define messages that are meaningful throughout an application, because some predefined window classes already define values in this range. For example, predefined control classes such as BUTTON, EDIT, LISTBOX, and COMBOBOX may use these values. Messages in this range should not be sent to other applications unless the applications have been designed to exchange messages and to attach the same meaning to the message numbers. 
这里的消息不应该被发送到其它应用程序里，除非这样应用被用来设计交换消息和附到具有相同的含义的消息编号上。

Message numbers in the fourth range (0xC000 through 0xFFFF) are defined at run time when an application calls the RegisterWindowMessage function to retrieve a message number for a string. All applications that register the same string can use the associated message number for exchanging messages. The actual message number, however, is not a constant and cannot be assumed to be the same between different Windows sessions. 
使用RegisterWindowMessage函数去取得字符串的消息编号。

An application can create messages to be used by its own windows or to communicate with windows in other processes. If an application creates its own messages, the window procedure that receives them must interpret the messages and provide appropriate processing.

Windows reserves message-identifier values in the range 0x0000 through 0x03FF (the value of WM_USER - 1) and 0x8000 through 0xBFFF for system-defined messages. Applications cannot use these values for private messages. 
Values in the range 0x0400 (the value of WM_USER) through 0x7FFF are available for message identifiers defined by an application for its own use. Values in the range 0xC000 through 0xFFFF are available for message identifiers defined by an application for use in communicating with windows in other applications.

Windows returns a message identifier in the range 0xC000 through 0xFFFF when an application calls the RegisterWindowMessage function to register a message. The message identifier returned by this function is guaranteed to be unique throughout the system. Use of this function prevents conflicts that can arise if other applications use the same message identifier for different purposes.
