how can I undo a macro in Word? - SOLVED :)

nata7 As I mentioned briefly before, a macro can examine the date on which a tracked change was made, and decide whether to reject that change. The following macro asks you to enter the date that the changes were made. It then looks at each tracked change (all 3000 of them). If the change's date matches the date you entered, and if the font color of that change is red, then the macro rejects that change. Otherwise the change is ignored. The macro counts the number of changes it rejected, and displays the number in the status bar at the bottom of the Word window and in a message box when the macro finishes.

Sub RejectTimedRevision()
Dim objRev As Revision
Dim objDate As Date
Dim strDate As String
Dim lngCount As Long

GetDate:
strDate = InputBox(prompt:="Enter date of changes:", _
Title:="Reject Changes from Specified Date")
If strDate = "" Then Exit Sub
If IsDate(strDate) Then
objDate = CDate(strDate)
Else
MsgBox strDate & " is not a valid date. Try again."
GoTo GetDate
End If

For Each objRev In ActiveDocument.Revisions
If InStr(objRev.Date, objDate) And _
(objRev.Range.Font.ColorIndex = wdRed) Then
objRev.Reject
lngCount = lngCount + 1
StatusBar = CStr(lngCount) & " revisions rejected"
End If
Next objRev

MsgBox CStr(lngCount) & " revisions rejected"
End Sub
