I'm about to write an application in either Adobe Air or Silverlight, to run standalone, offline, on the desktop. It's a simple enough application that allows the user to enter text data and will then print formatted documents based on that information. The obvious place to store all this relational data is in a database. I believe Air...

I've asked several questions on Silverlight the last day or two (I have no experience with it), and I've had some high-level questions answered. I have another high-level question. How is N-Tier development done with Silverlight? What I am considering is a browser based UI and then a c# back-end containing all the business logic and data...
Anybody figured out how to activate a visual state within the namescope of the ItemsControl from within a DataTemplate applied to said ItemsControl's ItemTemplate? You obviously can't select the target from within Blend. I was wondering if there was some obvious loop hole that I am missing. ...
Our .Net 3.5 projects are delay signed and are registred with sn -Vr to allow debugging these assemblies on dev machines. Recently we ported some projects to Silverlight 3.0 and found out that sn -Vr won't allow to execute a delay signed silverlight assembly through iexplorer. Is there a way to execute a delay signed silverlight applic...

I tried setting the "Name" property on...

I'm interested in creating a UPnP control point in Silverlight. To me that implies that I'll need to use COM interop with Microsoft's upnp.dll (and the SL application will have to be out of browser and platform specific). Is there any source code available in C# that shows how to create a control point with Microsoft's stack? If there...
Hello, When the user moves the mouse over an object, I'm trying to do some hit-testing in my MouseMove event handler to detect when the cursor is w/i a certain distance from an edge of the object. I suspect that in the MouseEnter handler I need to store the location of the object, then in MouseMove compare e.GetPosition(this) to th...

While the search is in progress, I'd like to change the gui accordingly: - Disable the Search button - Enable a Cancel button - etc Usin...
