Examples
The following code example adds a line of text to the current document and then displays a message box that asks whether to remove the text. If you click OK, then the example uses the Undo method to remove the text.
This example is for a document-level customization.
Private Sub DocumentUndo()
Me.Range(0, 0).Text = "A line of text"
If DialogResult.OK = MessageBox.Show( _
"Would you like to undo the text insertion?", "Test", _
MessageBoxButtons.OK) Then
Me.Undo(1)
End If
End Sub
private void DocumentUndo()
{
string newText = "A line of text";
object start = 0;
object end = 0;
Word.Range range1 = this.Range(ref start, ref end);
range1.Text = newText;
if (DialogResult.OK == MessageBox.Show(
"Would you like to undo the text insertion?", "Test",
MessageBoxButtons.OK))
{
object Times = 1;
this.Undo(ref Times);
}
}
