I am facing a problem with pdf viewer. They day I developed a page with pdf viewer activeX control in it. It was working fine.
What I had done is taking varbinary data from SQL and linking it with the viewer path. and when I hit run I was able to see pdf file properly.
But later night I got pop up to update Adobe pdf , I clicked ok and it updated my Adobe. Next day when I run the same program I see the pdf viewer to be grey , not showing file at all.
I thought that would be problelm with update ,so I uninstalled that version and re install old version. But still my pdg viewer is showing only grey.
And what version and bit are you using of Ignition and Java? Are you able to see the PDF document in the client and not the designer? In most cases the PDF will not show in the designer, unless it is in runtime, but will show in the client.
I think the update broke something. I spoke with another user who has a very similar situation. The PDF viewer worked fine, he updated Adobe reader, and now it doesn’t work.
As stated in the users manual, the ActiveX module is provided as-is, with limited technical support.
We are aware of the improvements that are needed.
A possible solution is the PDF Viewer in the Reporting Module. The only downside is if you don’t currently have this module on your license.
I had no idea that the activeX pdf viewer was able to take raw varBinary/blob data and then display the pdf. Everything is usually passed by a file path that the component then loads and displays. If I'm understanding you correctly and you were able to pull blob data from your database and then get the activeX component to display the pdf then that is functionality I didn't know the activeX component had.
There are two solutions that I see here. The easiest would be to upgrade and then use the pdf viewer module that was posted by @nathan.
Option 2 would be read the blob data from your database, write it to disk as pdf file, and then try and use the Ignition pdf viewer to view the file.
