One or more ActiveX Controls could not be displayed–InfoPath Ink Control Not working

Today I was debugging an error in InfoPath Form, in particular InfoPath 2010 installed in an typical SharePoint Farm. Error was more generic and could deviating you from actual solution.

Error was

One or more ActiveX Controls could not be displayed because either:

1) Your current security settings prohibit running ActiveX controls on this page, or
2) You have blocked a publisher of one of the controls.

As a result, the page might not display correctly.

With this when you start you will obvious end up in links that will suggest some registry changes. And few links suggest you add web URL as trusted Site etc. After all these you will see the issue still.

After few tries you may change the query to see “Ink Control not working” which will lead you to results of articles taking about Ink Control not supported in browser enabled InfoPath forms.

At this point I figured, that It was something related to missing ActiveX control, Usually when you have Custom ActiveX control you need to deploy it to the system that will fill InfoPath forms, refer this link for details.But Ink Control is out of the box control and it should be part of system that has InfoPath Installed.

That is when I figured out that Ink Control is not for regular PC but it is intended to be used by Tablet PC users. So in fact error is right InfoPath filler could not locate the Ink Control Active X dll. How do we fix it, easy Install the Ink Control, which is part of Microsoft Windows XP Tablet PC Edition Software Development Kit 1.7. Once you Install InfoPath with Ink Control will just work fine.

Couple of take away here.

  1. You cannot expect end user system to have this SDK installed nor it is a corrective measure.
  2. Reason I said it is not a corrective measure is because of the fact, Ink Control was to help user draw something , not  to capture user signature (what most people think and use this for)
  3. Refer this to see an example of how it is used also Microsoft suggest that we use Digital signature not Ink Control for capturing Signature (because of security).
  4. If you have a pressing need then you can package the ActiveX control and deploy as part of the solution.

Let me know your thoughts.
