Windows 9xis usually used to determine whether the files rundll32.exeand rundll.exe are
There may be strangers. However, since the functions of these two programs were originally used only within Microsoft, there may be few friends who really know how to use them. Well, if you still don't know
Let me tell you.
First, please make a small experiment (please save the results of the program you are running in advance, otherwise ...):
Click Start-Program-MS-dos to enter the DOS window, and then type
"Rundll32.exe user.exe, restartwindows", Press enter, then you will see that the machine has been restarted! How is it interesting?
Of course, the function of rundll is not just to restart your machine. In fact, rundll, as its name implies, also executes DLL. Its function is to call Windows dynamic link library in the form of command columns,
The difference between rundll32.exeand rundll.exe is that the former is a 32-bit link database, and the latter is a 16-bit link database. Their command format is:
Rundll. EXE ,,
Note the following three points: 1. the DLL file name cannot contain spaces. For example, the file is
C: Program Files directory. You need to change this path to C: progra ~ 1; 2. the DLL file name and the DLL entry point must have fewer commas. Otherwise, the program will fail and no information will be provided! 3. This is the most important point: rundll cannot be used to call a DLL containing return value parameters, for example, GetUserName () in WIN32API (),
Gettextface. In Visual Basic, a shell is provided to execute an external program. The format is:
Shell "command column"
If rundll32.exe is ready to use shell commands, it will make your VB program have effects that are hard to achieve or even unable to be implemented using other methods: restart is still used as an example. The traditional method requires you to create a module in the VB project, then write the winapi declaration before calling in the program. Now, you only need one sentence:
Shell restart rundll32.exe user.exe, restartwindows "is done! Is it convenient?
More?
In contrast, rundll32.exe has unique advantages in calling various windows control panels and System Options. Next, I will list the rundll commands I have collected over the Internet as follows (useful, saving you a lot of time calling Windows APIs !!), For reference in programming:

Of course, not only Visual Basic, but other programming languages such as Delphi. VisualC ++ can also access
Call External commands to use these functions of rundll.
. The flexible use of rundll will make your program design easier and get twice the result with half the effort!
The above content is taken from programming technology.
The difference between rundll32.exeand rundll.exe is that the former is a 32-bit link database, and the latter is a 16-bit link database.
