How to: Programmatically Extend Ranges in Documents

After you define a Range object in a Microsoft Office Word document, you change its start and end points by using the MoveStart and MoveEnd methods. The MoveStart and MoveEnd methods take the same two arguments, Unit and Count. The Count argument is the number of units to move, and the Unit argument can be one of the following WdUnits values:

Applies to: The information in this topic applies to document-level projects and application-level projects for Word 2013 and Word 2010. For more information, see Features Available by Office Application and Project Type.

The following example defines a seven-character range. It then moves the start position of the range seven characters after the original start position. Because the end position of the range was also seven characters after the start position, the result is a range that consists of zero characters. The code then moves the end position seven characters after the current end position.

To extend a range

Define a range of characters. For more information, see How to: Programmatically Define and Select Ranges in Documents.

The following code example can be used in a document-level customization.
```
Dim rng As Word.Range = Me.Range(Start:=0, End:=7)
```
```
object start = 0;
object end = 7;
Word.Range rng = this.Range(ref start, ref end);
```
The following code example can be used in an application-level add-in. This example uses the active document.
```
Dim rng As Word.Range = Me.Application.ActiveDocument.Range(Start:=0, End:=7)
```
```
Word.Range rng = this.Application.ActiveDocument.Range(0, 7);
```

Use the MoveStart method of the Range object to move the start position of the range.

rng.MoveStart(Unit:=Word.WdUnits.wdCharacter, Count:=7)

rng.MoveStart(Word.WdUnits.wdCharacter, 7);

Use the MoveEnd method of the Range object to move the end position of the range.

rng.MoveEnd(Unit:=Word.WdUnits.wdCharacter, Count:=7)

rng.MoveEnd(Word.WdUnits.wdCharacter, 7);

Document-Level Customization Code

To extend a range in a document-level customization

The following example shows the complete code for a document-level customization. To use this code, run it from the ThisDocument class in your project.

' Define a range of 7 characters. 
Dim rng As Word.Range = Me.Range(Start:=0, End:=7)

' Move the start position 7 characters.
rng.MoveStart(Unit:=Word.WdUnits.wdCharacter, Count:=7)

' Move the end position 7 characters.
rng.MoveEnd(Unit:=Word.WdUnits.wdCharacter, Count:=7)

// Define a range of 7 characters. 
object start = 0;
object end = 7;
Word.Range rng = this.Range(ref start, ref end);

// Move the start position 7 characters.
rng.MoveStart(Word.WdUnits.wdCharacter, 7);

// Move the end position 7 characters.
rng.MoveEnd(Word.WdUnits.wdCharacter, 7);

Application-Level Add-in Code

To extend a range in an application-level add-in

The following example shows the complete code for an application-level add-in. To use this code, run it from the ThisAddIn class in your project.

' Define a range of 7 characters. 
Dim rng As Word.Range = Me.Application.ActiveDocument.Range(Start:=0, End:=7)

' Move the start position 7 characters.
rng.MoveStart(Unit:=Word.WdUnits.wdCharacter, Count:=7)

' Move the end position 7 characters.
rng.MoveEnd(Unit:=Word.WdUnits.wdCharacter, Count:=7)

// Define a range of 7 characters.
Word.Range rng = this.Application.ActiveDocument.Range(0, 7);

// Move the start position 7 characters.
rng.MoveStart(Word.WdUnits.wdCharacter, 7);

// Move the end position 7 characters.
rng.MoveEnd(Word.WdUnits.wdCharacter, 7);
