Scripting Runtime DLL Library Overview
This section describes the Scripting Runtime DLL library, scrrun.dll, which offers Dictionary objects to store pairs of keys and values. scrrun.dll also offers FileSystemObject objects for you to manage local file systems.
Microsoft provides a number of runtime objects through a single DLL library:
- CreateObject("Scripting.Dictionary") - Returning an empty Dictionary object for you script code
to store pairs of keys and values. A Dictionary object is similar to associate array in Perl,
or a hash table in Java.
- CreateObject("Scripting.FileSystemObject") - Returning a FileSystemObject object
representing the file systems on the local machine.
- CreateObject("Scripting.FileSystemObject").Drives - Returning a collection of Drive objects representing
logical drives defined on the local machine.
- CreateObject("Scripting.FileSystemObject").GetFolder(path_name) - Returning a Folder object
representing the file folder of the specified path name.
- CreateObject("Scripting.FileSystemObject").GetFile(path_name) - Returning a File object
representing the file of the specified path name.
- CreateObject("Scripting.FileSystemObject").OpenTextFile(...) - Returning a TextStream object
representing an input and output text stream channel linked to the specified file.
scrrun.dll is available for client-side scripting with IE, server-side scripting with IIS,
and shell scripting with WSH. But using FileSystemObject and related objects on the client side
with IE is restricted for security reasons.
