将活动点移到给定位置。
命名空间： EnvDTE
程序集： EnvDTE（在 EnvDTE.dll 中）
语法
声明
Sub MoveToPoint ( _
Point As TextPoint, _
Extend As Boolean _
)
用法
Dim instance As TextSelection
Dim Point As TextPoint
Dim Extend As Boolean
instance.MoveToPoint(Point, Extend)
void MoveToPoint(
TextPoint Point,
bool Extend
)
void MoveToPoint(
[InAttribute] TextPoint^ Point,
[InAttribute] bool Extend
)
function MoveToPoint(
Point : TextPoint,
Extend : boolean
)
参数
Point
类型：EnvDTE.TextPoint必需。将字符移动到的位置。
Extend
类型：System.Boolean可选。默认值为 false。确定是否扩展当前的选定范围。如果 Extend 为 true，则选定内容的活动端会移到该位置，而定位端保留在原地。否则，两端都将移动到指定位置。此参数仅适用于 TextSelection 对象。
示例
Sub MoveToPointExample()
' 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
' selected text.
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
End Sub
