I have a winfrom application with vb.net. I want to add google maps to it . Like I want to search address and point it in the map. But it shows script error when I run it and the map is not loading correctly

What I have tried:

Dim getaddress As New StringBuilder
      getaddress.Append("https://www.google.com/maps?q=")
      If Not txtPostCode.Text = "" Then
          getaddress.Append(txtPostCode.Text)
      End If
      WebBrowser1.Navigate(getaddress.ToString())
