I have completed a proof of concept and am working on my module for Electronic Signtaure Capture.

I found a great Marcus Egger article that helped out tons

or in PDF format

To sum up the scope of the project:
I need to capture a signature using a Tablet PC and attach it to a specified Document. I do this using Windows XP Tablet SDK 1.5 Ink Collector Control (more on that in the Egger article) and XFRX or Crystal Reports

I need to render a .FRX or .RPT to a PDF File, then create a key, encrypt it, then ecrypt the PDF file and the Signature (stored in a Serialized Ink Format)

I am using the Windows Crypt API, Tablet XP SDK and XFRX from eqeus with great success.

I'm guessing not many people here have tried this so I hope this helps anybody who wants to do this very task in the future.

Lessons learned:
VFP 6 does not play nice with the Tablet SDK's ink object when it comes to .GIF files, VFP 8 does.

XFRX is a really cool product that extends FRX files to Word, Excel, HTML and PDF with ease.

There is a good article in Fox Talk on using the Windows Crypt API complete with examples that need very little changed to make them work in a production environment.

using PDF.OCX may not be documented or encouraged by many PDF exprets, but it works well as a viewer in VFP only when dragged and dropped on the form. Somehow I was quite unable to get a PDF to properly load when using CREATEOBJECT() and the proper ID for the PDF Viewer


so if any of you have any questions after reading all that I may be able to help.
