You can download and install ABCpdf ASP and copy the script below into a text file extension and save it as a .vbs extension. Copy your PDF file into the script folder and named it 'abc.pdf'. Run the script by a double-click.

theDoc.Read "abc.pdf"
theDoc.AddFont "Helvetica-Bold"
theDoc.FontSize=16
theDoc.Rect.Pin=1
Dim theIDs, theList
theIDs = theDoc.GetInfo(theDoc.Root, "Field IDs")
theList = Split(theIDs, ",")
For Each id In theList
theDoc.Page = theDoc.GetInfo(id, "Page")
theDoc.Rect.String = theDoc.GetInfo(id, "Rect")
theDoc.Color.String = "240 240 255"
theDoc.FillRect()
theDoc.Rect.Height = 16
theDoc.Color.String = "220 0 0"
