Hi,

I am having an iball Pen tablet which consist of a wireless pen (Model no -5540U).  My core requirement is to use of this for electronically sign on a web form in any Image control in .net 3.5 framework using ASP.NET  C# so that I can put the signature on appropriate place in web form.

Please help in this regards and provide the solution in ASP.NET C#.

I would waste any time, trying to do all this by myself. I would definetely opt for a thrid-party plugin that would do such a thing. But wait - even I hate the ActiveX or client-side installations for this behavior. 

I just did a search on the web - and found the "Web Signature". It seems to be easy to integrate, easy to use as well. It charges you a $199 per domain - which I feel is a worthy price. But you may decide based on your budget.

hi,

You must first create a key-file for exclusive use by all of your published applications.  You would need to save this file in a VERY SECURE location.  Some of the larger companies use their own vault containing a server that holds the file.
