i am developing an asp.net application. i am new to asp.net and need to know how to get started implementing my conceptual design. first, when the user opens a browser and navigates to the web app he will be presented with a login screen. upon successfull login the application is going to present the user with a spreadsheet embedded into the page in the browser. below the spreadsheet will be a button that when clicked will try to locate on the client's box a program called AccuTerm. once an accuterm session has successfully been initialized the application will pass data from the embedded spreadsheet to the accuterm session using accuterm's api. so basically there will be a server side component that posts the spreadsheet data to the users browser and a client side component that will consume the spreadsheet data. is it possible to manipulate the clients computer i.e. accuterm through asp.net?
