I needed to use a different connection string for database access, depending on what host was serving my Silverlight application. Here's how to do it:
Dim url As String = HtmlPage.Document.DocumentUri.ToString()
string url = HtmlPage.Document.DocumentUri.ToString();
I've been paid as a programmer since 1982 with experience in Pascal, and C++ (both self-taught), and began writing Windows programs in 1991 using Visual C++ and MFC. In the 2nd half of 2007, I started writing C# Windows Forms and ASP.Net applications, and have since done WPF, Silverlight, WCF, web services, and Windows services.
My weakest point is that my moments of clarity are too brief to hold a meaningful conversation that requires more than 30 seconds to complete. Thankfully, grunts of agreement are all that is required to conduct most discussions without committing to any particular belief system.
