    Problems with digital signitures

    Hello,

    I need to first apologize up front if this was already covered in another thread. I have created a form using MS InfoPath 2010. The form has a digital signature box, and a submit box at the bottom. When users digitally sign the form then hit the submit button it emails me a copy of the completed form however the digital signature is not visible and I can’t figure out why. Finally would like to know if there is any way to hide the submit button until the form is digitally signed. Any help on this would be great.

    Thanks again,

    Mike

    Hi Mike,

    You can add conditional formatting rule to the submit button to hide it if the digisig is not in the XML.

    Why can't they see the digisig?  Not sure. Can you include a screenshot of the submitted form and the email view? Go to Options tab and upload an image.

    Thanks!

    This is the HTML view of the form from MS outlook.

    Thank you for your help. As you can see in this image the form is digitally signed. I used the built in submit button and had it send the form template with the email. In the next image you can see where the digital signiture is missing.

    Hi again,

    Thanks for attaching the image.

    Are you using the same version of Outlook? Please make sure you are.

    If it is still an issue, I am guessing it's a limitation in InfoPath's support for converting the HTML of the digisig to WordML (used with Outlook email).

    One workaround, would be to add an optional section to your form and a formatting rule to show it when the form is signed. You could just add a rule on the Signature node to set a date time field and then display that. Not a great solution since they wouldn't see who signed it.

    The signature block contains a schema and the image of the entire form signed (under my:signatures1/my:signatures2/Signature/Object/SignedProperties/SignatureProperty/sp:ScreenDumpPNG).

    In theory, one could create a view with a picture control and copy this image into it using a rule and switch to that view before sending the form. That would result in a nice pixel perfect rendering of the signed form.

    I tried to manually modify a rule in the manifest.xsf to get it to copy the image to a picture control, but it was a no go.

    I'm guessing we could add some code to qRules to do this. Might be a cool way to get the image of the form too (for people that manually sign the form - since we can't automate signing it).

    :)

    Jimmy got it working so that it extracts the image of the signed doc using a fancy xpath. Check out the rule on the second button of the attached xsn. Also, take a look at the view that it switches too. You'll need to add the digisig to your form so it shows up visually, but should be easy to use this technique to email a signed image of the doc around.
