' Before running, select text in an open document.
Dim txtSel As TextSelection
Dim strTS As String, strAnswer As String, bIsOpen As Boolean
txtSel = DTE.ActiveDocument.Selection
strTS = txtSel.Text
' Check to see if UndoContext object is already open.
If DTE.UndoContext.IsOpen = True Then
bIsOpen = True
Else
' Open the UndoContext object to track changes.
DTE.UndoContext.Open("RemoveNewLines", False)
End If
MsgBox("Current IsAborted value: " & DTE.UndoContext.IsAborted)
' Perform search for newline characters and remove them.
If strTS <> "" Then
txtSel.Delete()
strTS = Replace(strTS, vbNewLine, "", Compare:=vbTextCompare)
txtSel.Insert(strTS)
End If
' Check to see if you want to discard changes.
strAnswer = MsgBox("Do you want to discard all changes made?", vbYesNo & vbQuestion)
If strAnswer = True Then
DTE.UndoContext.SetAborted()
MsgBox("Current IsAborted value: " & DTE.UndoContext.IsAborted)
End If
' If UndoContext was already open, don't close it.
If bIsOpen = True Then
