Automation (formerly OLE Automation) is a feature that programs use to expose their objects to development tools, macro languages, and other programs that support automation. For example, a spreadsheet program may expose a worksheet, chart, cell, or range of cells, each as a different type of object. A word processor might expose objects such as an application, a document, a paragraph, a sentence, a bookmark, or a selection.
When a program supports Automation, you can use Visual Basic for Applications to access the objects it exposes. You manipulate these objects in Visual Basic for Applications by invoking methods on the object or by getting and setting the object's properties.
You can use the code samples in this article to control Microsoft Word from Microsoft Access 2000, Microsoft Excel 2000, Microsoft PowerPoint 2000, Microsoft Visual Basic for Applications, or any other client that supports Automation to control Word.
Getting StartedThere are four main steps to automate Word for Windows:
Step 1: Add a Reference to the Word 9.0 Object LibraryTo add a reference to the Microsoft Word 9.0 Object Library using Microsoft Access 2000, Microsoft PowerPoint 2000, or Microsoft Excel 2000, follow these steps:
Adding the Microsoft Word 9.0 Object Library reference allows your program to access Microsoft Word Online Help and the Microsoft Word Visual Basic for Applications constants, properties, and methods. Note that the Microsoft Word 9.0 Object Library reference is required to automate the Word object types directly.
Adding a reference to the Microsoft Word 9.0 Object Library is called early binding.
For more information about Object Binding, please see the following article in the Microsoft Knowledge Base:

Step 2: Declare the Object VariableTo declare an object variable, you dimension the variable just as you dimension any variable, except that you specify the type when declaring the object. For example, Word.Application, Document, and Paragraph are separate Word Objects.
The following sample command line declares the variable objWD as an object of type Word.Application:
Step 3: Set the VariableThere are two Visual Basic functions you can use to "bind" the already declared object variable to Word: CreateObject and GetObject. The primary differences are that the CreateObject function creates a new instance of Word, and the GetObject function uses an existing, or already running instance of Word. You can also use GetObject to bind your object variable to a specific Word document.
The following sample command lines bind the objWD variable to Word using the CreateObject function:
The following sample command lines bind the objWdDoc variable to a specific Word document:
NOTE: It is recommended to use only the CreateObject function to automate Word for Windows. The GetObject function can cause unpredictable behavior if WordMail is running or if a Word document is embedded inside another program.

Step 4: Use Properties and Methods to Automate WordWhen you complete steps 1 through 3, you can use the object variable to automate Word.
The following sample macro uses automation to create a Word object, create a new document, add some text, and save the document.
NOTE: The following sample macro duplicates the process described in the AutomateWord macro and runs directly in Word:
