Modifying a Portion of a Document
Visual Basic includes objects that you can use to modify the following document elements: characters, words, sentences, paragraphs, and sections. The following table includes the properties that correspond to these document elements and the objects they return.
|This expression||Returns this object|
|Words ( index)||Range|
|Characters ( index)||Range|
|Sentences ( index)||Range|
|Paragraphs ( index)||Paragraph|
|Sections ( index)||Section|
When these properties are used without an index, a collection object with the same name is returned. For example, the Paragraphs property returns the Paragraphs collection object. However, if you identify an item within these collections by index, the object in the second column of the table is returned. For example,
Words(1) returns a Range object. After you have a Range object, you can use any of the range properties or methods to modify the Range object. For example, the following instruction copies the first word in the selection to the Clipboard.
Sub CopyWord() Selection.Words(1).Copy End Sub
Note The items in the Paragraphs and Sections collections are singular forms of the collection, specifically Paragraph objects and Section objects, rather than Range objects. In fact, most collections in the Word object model have singular form objects with which you can work. However, the Range property (which returns a Range object) is available from both the Paragraph object and the Section object, and from most other objects that are children of collections. For example, the following instruction copies the first paragraph in the active document to the Clipboard.
Sub CopyParagraph() ActiveDocument.Paragraphs(1).Range.Copy End Sub
All of the document element properties in the preceding table are available from the Document, Selection, and Range objects. The following examples demonstrate how you can drill down to these properties from Document, Selection, and Range objects. The following example sets the case of the first word in the active document.
Sub ChangeCase() ActiveDocument.Words(1).Case = wdUpperCase End Sub
The following example sets the bottom margin of the current section to 0.5 inch.
Sub ChangeSectionMargin() Selection.Sections(1).PageSetup.BottomMargin = InchesToPoints(0.5) End Sub
The following example double spaces the text in the active document (the Content property returns a Range object).
Sub DoubleSpaceDocument() ActiveDocument.Content.ParagraphFormat.Space2 End Sub
Modifying a group of document elements
To modify a range of text that consists of a group of document elements (characters, words, sentences, paragraphs, or sections), you need to create a Range object. The Range method creates a Range object given a start and endpoint. For example, the following instruction creates a Range object that refers to the first ten characters in the active document.
Sub SetRangeForFirstTenCharacters() Dim rngTenCharacters As Range Set rngTenCharacters = ActiveDocument.Range(Start:=0, End:=10) End Sub
Using the Start and End properties with a Range object, you can create a new Range object that refers to a group of document elements. For example, the following instruction creates a Range object (
rngThreeWords) that refers to the first three words in the active document.
Sub SetRangeForFirstThreeWords() Dim docActive As Document Dim rngThreeWords As Range Set docActive = ActiveDocument Set rngThreeWords = docActive.Range(Start:=docActive.Words(1).Start, _ End:=docActive.Words(3).End) End Sub
The following example creates a Range object (
rngParagraphs) beginning at the start of the second paragraph and ending after the third paragraph.
Sub SetParagraphRange() Dim docActive As Document Dim rngParagraphs As Range Set docActive = ActiveDocument Set rngParagraphs = docActive.Range(Start:=docActive.Paragraphs(2).Range.Start, _ End:=docActive.Paragraphs(3).Range.End) End Sub
