Chapter 1 Basic Principle of Chinese Character Input Method under Windows9x System
The Chinese character input method under the Windows system is actually converted into a national or Chinese string in a certain coding rule, enters the destination. Because the application is different, the user cannot design the conversion program itself, so the Chinese characters will naturally fall into Windows system management.
First, the relationship between input method and system
Keyboard Event Application | | Windows User.exe | Input Law Manager | Input Method
After the system's keyboard event has Windows User.exe software, user.exe is transmitted to the input method in the input method in the input method in the Input Method Manager, the Manager, the Manager, the INPUT METHOD MANAGER, the input method. According to the user-coded dictionary, the translation keyboard event is the corresponding Chinese character (or Chinese character string), and then reverse in User.exe, user.exe will pass the translated keyboard event to the currently running application, to complete the Chinese character input of.
Second, the composition of the Chinese character input method
The name of the Chinese character input method in the Microsoft Windows 9x system is "Input Method Editor", referred to as IME, the program name of the input method is: *. IME, the data file name address * .mb, ie, the normally input method coding table (dictionary).
In fact, IME file is a dynamic connection library program (DLL), which is different from DLL files, but the name is different.
The general Chinese character input method consists of three windows:
Status Windows - Displays the current input method (Chinese or English information);
Code Enter Windows - Displays the current hit button;
Chinese character selection window (Candidates Windows) listing all Chinese characters (strings) currently available for users to choose or query.
The above three windows are managed by the basic user interface function.
Now we use dumpbin.exe to open Microsoft's Pinyin input method (windows / system / winpy.ime) to see what it makes up (here a Windows98 is an example, and assumes that the Windows system is installed under C: disk):
C: / dumpbin c: /windows/system/winpy.ime
