Hello sippyuconn,

Do u have the source code for your standalone app or not?
If u do, the simplest way is to wrap the reusable functionality into user
controls, which can be consumed by the different clients, and consider to
move the logic to external services - making your controls like gateways.

If u don't have the source code, then I suppose the screen scraping the only
way to reuse functionality

sippyuconn,

   You could always just refactor your app into components that aren't tied
to the UI.  Then you can choose to expose that functionality through
remoting, COM interop, or whatever mechanism suits you.

Hi,

In my opinion, you may build the reusable functions into a Web Service,
then your WinForm application and other applications can call these
functions from the Web Service.

FYI, the following link discusses "Getting Started with Web Services":

Hope this helps.
