使用例

派生クラス TextBox を使用するコード例を次に示します。切り取り、コピー、貼り付け、元に戻すなどの各操作を実行する MenuItem オブジェクトの Click イベント ハンドラを用意します。この例では、textBox1 という名前の TextBox コントロールが作成されている必要があります。

Visual Basic

Private Sub Menu_Copy(sender As
 System.Object, e As System.EventArgs)
    ' Ensure that text is selected in the text box.   
    If textBox1.SelectionLength > 0 Then
        ' Copy the selected text to the Clipboard.
        textBox1.Copy()
    End If
End Sub
 
Private Sub Menu_Cut(sender As
 System.Object, e As System.EventArgs)
    ' Ensure that text is currently selected in the text box.   
    If textBox1.SelectedText <> ""
 Then
        ' Cut the selected text in the control and paste it into the
 Clipboard.
        textBox1.Cut()
    End If
End Sub
 
Private Sub Menu_Paste(sender As
 System.Object, e As System.EventArgs)
    ' Determine if there is any text in the Clipboard to paste into
 the text box.
    If Clipboard.GetDataObject().GetDataPresent(DataFormats.Text)

        ' Determine if any text is selected in the text box.

            ' Ask user if they want to paste over currently selected
 text.

 to paste over current selection?", _

 and paste.

        End If 
        ' Paste current text in Clipboard into text box.
        textBox1.Paste()
    End If
End Sub

    ' Determine if last operation can be undone in text box.   
    If textBox1.CanUndo = True Then
        ' Undo the last operation.
        textBox1.Undo()
        ' Clear the undo buffer to prevent last action from being redone.
