Set Magnification for URL in MS Access WebControl Using VB

In MS Access, I have a webcontrol on a form.  I want to be able to force magnification for the URL to 125 percent.  I have found several articles on Google about this, but nothing seems to work for me.  Here is what I have now - the last line represents the best suggestion I was able to find on the intrawebs:

DoCmd.OpenForm "WebBrowser", acNormal
DoCmd.Maximize
       
Forms!WebBrowser.RecordSource = "Wordpress"
    Forms!WebBrowser.Filter = "[Select]=-1"
    Forms!WebBrowser.FilterOn = True

'''''  the URL comes from tbWordpress from either be in Site, NewPost or NewPage in the Wordpress table
    Forms!WebBrowser!WebBrowser0.ControlSource = "NewPost"
   
   
    Forms!WebBrowser!WebBrowser0.ExecWB OLECMDID_OPTICAL_ZOOM, ExecOpt.OLECMDEXECOPT_DONTPROMPTUSER, 150, DBNull.Value
