To view a CHM file, you must
use the HTML Help (HH.EXE) utility, which doesn??™t come with Server Core. When you need to view
CHM files, the best option is to open them on the client machine. You can do this at the command
line by typing HH MappedDrive:\FilePath\FileName and press Enter. The file opens as usual, but
you??™ll be looking at it from the host system. Copying the required help files to your local system is
also an option to improve help performance.
Accessing DLLs Using the RunDLL32 Utility
It??™s easy to think of a command as a built-in function within CMD.EXE and a utility as an external
application that you run. However, the command line presents a third alternative, one that you
might not have ever considered. The RunDLL32.EXE file is a utility that you can??™t run directly.
Instead, you feed it a DLL that contains one or more externally accessible functions and add any
arguments that the function requires as part of your input. For example, let??™s say you want to add
a beep to your batch file. You can use the MessageBeep() function found in the User32.DLL file by
adding this command to a batch file or script.
RunDLL32 User32.
