Frequently Windows9x friends must have two files that rundll32.exe and rundll.exe
It will be unfamiliar, but because the functions of these two programs are originally limited to internal use in Microsoft, they are truly
I know how to use them. So good, if you are still unclear, then
Let me tell you.
First, please do a small experiment (please save the results of the program you are running in advance, otherwise ...):
Click "Start-Program-MS-DOS Mode" to enter the DOS window, then type
"Rundll32.exe User.exe, RestartWindows", then press Enter, then you will see, machine
The device is restarted! How is it, is it very interesting?
Of course, Rundll's function is more than just restarting your machine. In fact, Rundll, as the name suggests,
Running the DLL, its function is to call the Windows dynamic link library by command line.
The difference between Rundll32.exe and Rundll.exe is that the former is a link library that calls 32-bit, and the latter is transport
For 16-bit link libraries, their command format is:
Rundll.exe,
Here you should pay attention to three points: 1. DLL file name cannot contain spaces, such as the file is located
C: / program files / directory, you have to change this path to C: / Progra ~ 1 /; 2.DLL file name and DLL
The comma between the entry points cannot be small, otherwise the program will be wrong and will not give any information! 3. This is the most important
One point: Rundll cannot be used to call DLL containing return value parameters, such as getUserName () in Win32API,
GetTextFace (), etc. In Visual Basic, a directive shell, a handle
The formula is:
Shell "Command Line"
If you can use Rundll32.exe to use the shell directive, you will make your VB program have other methods.
Even if it is unable to achieve: still use it as an example, the traditional method requires you to build one in the VB project.
A module and then written to the declaration of WinAPI, and finally you can call it in the program. And now just one sentence:
Shell "Rundll32.exe User.exe, RestartWindows" is set! Is it convenient?
too much?
In fact, Rundll32.exe has unique in calling various Windows control panels and system options.
The advantages. Below, I will listed the Rundll's instructions collected on the Internet (very
Used, you can save a lot of time to call the Windows API! ! ) For everyone to quote in programming:
