EditPoint の使用例

更新 : 2007 年 11 月

次の例では、TextDocument オブジェクトを作成してテキストを追加し、EditPoint オブジェクト機能の一部を示します。

例

説明

以下の各関数では、文字オフセットのインデックス番号が 1 から始まりますが、IVsTextView および類似のインターフェイスでは、インデックス番号は 0 から始まります。EditPoint は VB オートメーションをサポートするように設計されているため、インデックス番号は 1 から始まります。

コード

Public Sub OnConnection(ByVal application As Object, ByVal connectMode_
 As Extensibility.ext_ConnectMode, ByVal addInInst As Object,_
 ByRef custom As System.Array) Implements_
 Extensibility.IDTExtensibility2.OnConnection

    applicationObject = CType(application, EnvDTE.DTE)
    addInInstance = CType(addInInst, EnvDTE.AddIn)
    EditPointExample1(applicationObject)
End Sub
Sub EditPointExample1(ByVal dte As DTE)
    Dim objTextDoc As TextDocument
    Dim objEditPt As EditPoint, iCtr As Integer

    ' Create a new text file.
    applicationObject.ItemOperations.NewFile("General\Text File")

    ' Get a handle to the new document and create an EditPoint.
    objTextDoc = applicationObject.ActiveDocument.Object("TextDocument")
    objEditPt = objTextDoc.StartPoint.CreateEditPoint

    ' Insert ten lines of text.
    For iCtr = 1 To 10
        objEditPt.Insert("This is a test." & Chr(13))
    Next iCtr

    ' Replace the eighth word on the third line with a new word.
