Hi,

I need to digitally sign a document (Word/Excel) programatically using C#.
I found few posts on internet showing me how to just add a digital signature.

By default, i am using Microsoft Office Signing capabilities for this purpose.
Now, i want to embed an image to this Digital Signature Programatically and place it at the end of the file.

Can anyone help me?

Please note that if we try to add Digital Signature in Word/Excel file it asks us to select an image. I need to do that programatically

Thanks in Advance
