Why can't I embed the pdf in my web page anymore

For weeks I have been using:

        pdfParam = "search="" + searchString + ""&toolbar=0&messages=0&navpanes=0&view=Fit";        

        url = url + "#" + Server.UrlPathEncode( pdfParam );                 

         if ( openType == "OpenOnPage" )           

         {           

             var x = GetPDF( GetPDFDiv() );           

             x.Text = "<object " +                       

                           "class=\"Object\" " +                       

                           "width=\"100%\" " +                       

                           "height=\"980x\" " + 

                          "type=\"application/x-pdf\" " +                       

                          "data=\"" + url + "\" " +                       

                          "> " +                      "

                         This browser does not support embedded PDFs. Click here to view it.         couldn't figure out to put html text in here

              ShowPDF();           

         }

Today, the PDF showed for a moment, and then an error from PDF said the "Adobe PDF Reader DC stopped working".  I was able to remove the pdfParams and then it showed ok, but the main thing I was trying to accomplish was search for a string so that the pdf was positioned to it.

So then I uninstalled the Reader and downloaded and installed the latest one.  Now I get the "This browser doesn't support..." message and it doesn't show in the page at all.  If I switch it to using an iframe, it shows, but I don't know how to use the parameters with an iframe.
