Whenever I want to write to the database, bind to these parameters (reusing the same command instances), set the Connection and Transaction properties, th...
I want to produce some library code that will be included into WPF applications. The library may pop up a Window, depending on circumstances. I can define the Window in XAML, but I'd like to treat the XAML as a template. At runtime, at the time the Window is being created so that it can be displayed, I want to replace certain tags in t...

Hello, My code follows. I have six items (indices 0-6) and I'm trying to check if one has been selected or not. If not, then messagebox yells at you to select one.
