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 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 Excel 98 Macintosh Edition, Microsoft PowerPoint 98 Macintosh Edition, or any other client that supports Automation to control Word.

Getting Started
There are four main steps to automate Word 98 Macintosh Edition:
 * 1) Add a reference to the Microsoft Word 8.0 Object library.
 * 2) Declare a variable as a Word object type.
 * 3) Assign the object returned by the CreateObject function to the object variable you declared in step 2.
 * 4) Use the properties and methods of the object variable to automate Word.

Step 1: Adding a Reference to the Word 8.0 Object Library
To add a reference to the Microsoft Word 8.0 Object Library using Microsoft PowerPoint 98 Macintosh Edition or Microsoft Excel 98 Macintosh Edition, follow these steps:
 * 1) In Microsoft PowerPoint or Excel, on the Tools menu, point to Macros, and then click Visual Basic Editor.
 * 2) In the Visual Basic Editor, on the Tools menu, click References.
 * 3) In the list of Available References, click to select (check) the Microsoft Word 8.0 Object Library check box.

Adding the Microsoft Word 8.0 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 Word 8.0 Object Library reference is required to automate the Word object types directly.

Adding a reference to the Word 8.0 Object Library is called early binding.

For more information about early binding, please see the following article in the Microsoft Knowledge Base:

138138 INFO: Late, ID, Early Binding Types Possible in VB for Apps

Step 2: Declaring the Object Variable
To 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": Dim objWD as Word.Application

Step 3: Setting the Variable
There 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: Dim objWD as Word.Application Set objWD = CreateObject("Word.Application")

The following sample command lines bind the objWdDoc variable to a specific Word document: Dim objWdDoc As Word.Document Set objWdDoc = GetObject("c:\my documents\doc1.doc")

Step 4: Use Properties and Methods to Automate Word
When you complete steps 1-3, 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. Sub AutomateWord ' Declare the variable. Dim objWD As Word.Application ' Set the variable (runs new instance of Word.) Set objWD = CreateObject("Word.Application") ' Add a new document. objWD.Documents.Add ' Add some text. objWD.Selection.TypeText "This is some text." ' Save the document. objWD.ActiveDocument.SaveAs filename:="mydoc.doc" ' Quit Word. objWD.Quit ' Clear the variable from memory. Set objWD = Nothing End Sub

NOTE: The following sample macro duplicates the process described in the AutomateWord macro and runs directly in Word: Sub WordMacro Documents.Add Selection.TypeText "This is some text" ActiveDocument.SaveAs filename:="mydoc.doc" Quit End Sub
