VBScript Reference Manual InduSoft Web Studio Scripting Dictionary Object A dictionary object is part of the Scripting type library. The dictionary object is a special type of an array which stores a data item that is associated with a unique key. The key, which is usually a number or a string, is used to retrieve an individual item. You can use a Dictionary when you need to access random elements frequently or need to access information contained in the array based on its value, not position. The Dictionary object has both Methods and Properties that can be used to manipulate the Dictionary.

OpenTextFile Opens a file and returns a TextStream object FileSystemObject Properties Properties Description Drives A Drives collection of all Drive objects available on the local machine. Collections returned by FileSystemObject method calls reflect the state of the file system when the collection was created. Changes to the file system after creation are not reflected in the collection. If the file system might be changed during the lifetime of the collection object, the method returning the collection should be called again to ensure that the contents are current. Set fs = CreateObject("Scripting.FileSystemObject") Set a = fs.CreateTextFile("c:\testfile.txt", True) a.WriteLine("This is a test.") a.Close In the code shown above, the CreateObject function returns the FileSystemObject (fs). The CreateTextFile method then creates the file as a TextStream object (a) and the VBScript TextStream Object WriteLine Method writes a line of text to the created text file. The VBScript TextStream Object Close Method flushes the buffer and closes the file. InduSoft, Ltd. 31
