newby's Web service problems, please help!!!

Question

Hi everyone, I am a newby but very interested in .NET and webservice, and I do want to learn something from your help. I am developing a small webservice using c# and it is really convenient. But I have some problems. I want to let the webservice to extract related information based on certain content of a HTML webpage, like get the date-of-birth and name of a person based on the person's ID(all these info are displayed on the HTML page) and display notifications if necessary. How can I make my webservice capable to read the HTML web page? And I tried to use MessageBox to display the notification but the webservice told me I should specify a ServiceNotification or DefaultDesktopOnly style, but I have no idea about them. Please tell me what to do. Thank you in advance

To read web page you could use System.Net.WebClient class. MessageBox.. I guess you are talking about WinForms class? Classes under System.Windows are not usable in asp.net pages or web services (well, at least most of them) (In case of messagebox, the message would pop up on the server...)
