I need to be able to view PDF files in a WebBrowser window, but I want to control how it is displayed. I have added the Acrobat Control for ActiveX, but I want to stop the WebBrowser control from opening Acrobat and displaying the file. In the WebBrowser1_BeforeNavigate2 sub, I'm checking for ".pdf" in the URL. If it is there, I am setting Pdf1.Visible = True and Pdf1.LoadFile URL. I tried using WebBrowser1.Stop so that it wouldn't continue and show the PDF, but that doesn't work. the reason I want to control showing the PDF is so I can take away the toolbar from the Reader program. I don't want my users to have access to the toolbar, because it allows them to open a new instance of IE.
