ActiveX control with no properties, methods, events

Admin
I was doing my development (IWS 8.0) in Windows XP on my dual boot computer. I added an Adobe PDF Viewer ActiveX control to a screen, set the 'src' property to my document's path and VOILA! it shows my document in the viewer. So far, so good.

I decided to change over to the Windows 7 environment (same computer, different boot OS). I ran the program and...the PDF doesn't show. So I go to look at the properties of the PDF viewer object and it shows NO properties, NO methods, and NO events. And of course it doesn't work. I even tried deleting that object and inserting another one, with the same results.

The Adobe PDF Viewer shows up in the list of ActiveX objects, so I assume that it should be available to use. After all, it works fine when I am running in XP. I even tried re-registering the control (using the 'Home\Tools\Register Controls' menu option, but it made no difference.

Is there something I'm doing wrong, or not doing? The rest of the project seems to work fine. Of course, I am VERY new to this development environment, so it is entirely possible that I overlooked something. Maybe I need to recreate the whole project from scratch, instead of modifying the one I created in XP?

Any help would be appreciated.
  • Hello @ChuckB,

    The same thing happened to me. I wanted to use the reader.ocx for a project I am working on for someone, and it appears that Adobe has removed all support for it, and it is not available for download. The Adobe blabla ActiveX object that you are seeing now is (I am assuming) for their plug-in into IE and other browsers, and it is not accessible by a Properties dialog. It looks to be purpose built with hard-coded links to the things that it does work on. I scoured what remains of the Internet search engines, and Adobe has removed virtually every entry having to do with the real reader .ocx and they're not saying anything. I suspect that it has to do with COM security and support issues surrounding ActiveX controls and the fact that it is only supported in Microsoft technology. In any case, I don't think any older version of the control will work or even register properly in current versions of Win 7, 8, 10 or whatever. It was the same thing that VLC did with the VLC media viewer .ocx, but they are open source and have no staff or money to keep the thing alive.

    I found two companies that still do offer an ActiveX control and one for a .NET, and I am using the demo version of Softonic ( http://activex-pdf-viewer.en.softonic.com/ , that's: h t t p : / / a c t i v e x - p d f - v i e w e r . e n . s o f t o n i c . c o m / without the embedded spaces) along with DynamicPDFViewer ( http://www.dynamicpdf.com/View-PDF-COM.aspx that's: h t t p : / / w w w . d y n a m i c p d f . c o m / V i e w - P D F - C O M . a s p x ), and a .NET control from LEADTOOLS http://www.leadtools.com (h t t p : / / w w w . l e a d t o o l s . c o m) , They all require purchased licenses, and have evaluation modes with a tatoo or annoying popups. 

    You can use the Web Browser control however to view .pdfs
