TextSelection.WordLeft Method
Moves the text selection left the specified number of words.
Namespace: EnvDTE
Assembly: EnvDTE (in EnvDTE.dll)
Syntax
'Declaration
Sub WordLeft ( _
Extend As Boolean, _
Count As Integer _
)
void WordLeft(
bool Extend,
int Count
)
void WordLeft(
[InAttribute] bool Extend,
[InAttribute] int Count
)
abstract WordLeft :
Extend:bool *
Count:int -> unit
function WordLeft(
Extend : boolean,
Count : int
)
Parameters
Extend
Type: System.BooleanOptional. Determines whether the moved text is collapsed or not. The default is false.
Count
Type: System.Int32Optional. Represents the number of words to move left. The default value is 1.
Remarks
If Extend is True, then the active end of the text selection is moved left Count number of words. Otherwise, the text selection is collapsed and positioned Count words left from the active end. If the beginning of the document is encountered before Count words, then the position remains at the beginning of the document.
If the value of Count is negative, then WordLeft performs like the WordRight method.
The active language manager for the text document defines the meaning of a "word."
Examples
Sub WordLeftExample()
' Before running this example, open a text document.
Dim objSel As TextSelection = DTE.ActiveDocument.Selection
If objSel.IsEmpty Then
' If there is no text selected, swap the words before and after
' the insertion point. We begin by selecting the word before
' the insertion point.
objSel.WordLeft(True)
If Not objSel.IsEmpty Then
' We can continue only if the selection was not already at
' the beginning of the document.
Dim strBefore As String = objSel.Text
' The text is saved in strBefore; now delete it and move
' past the following word.
objSel.Delete()
objSel.WordRight(True)
If objSel.Text.StartsWith(" ") Or objSel.Text.StartsWith(Microsoft.VisualBasic.ControlChars.Tab) Then
' The previous call to WordRight may have skipped some
' white space instead of an actual word. In that case,
' we should call it again.
objSel.WordRight(True)
End If
' Insert the new text at the end of the selection.
objSel.Insert(strBefore, vsInsertFlags.vsInsertFlagsInsertAtEnd)
End If
Else
' If some text is selected, replace the following word with the
' text selection.
Dim strSelected As String = objSel.Text
objSel.MoveToPoint(objSel.BottomPoint)
objSel.WordRight(True)
If objSel.Text.StartsWith(" ") Or objSel.Text.StartsWith(Microsoft.VisualBasic.ControlChars.Tab) Then
' The previous call to WordRight may have skipped some
' white space instead of an actual word. In that case, we
' should call it again.
objSel.WordRight(True)
End If
' Insert the text, overwriting the existing text and leaving
' the selection containing the inserted text.
objSel.Insert(strSelected, vsInsertFlags.vsInsertFlagsContainNewText)
End If
