I'm going to write an application in Silverlight that consists of 2 threads, one that plays sound and another that records sound. And whatever is recorded will be what was played plus some ambient noise. The problem is that Silverlight adds a delay to the sound to be played, and because I don't know how much is this delay, I would not k...
I'm just playing around with Windows Phone and trying to write an app for it. I can't seem to find a Trace.Assert in System.Diagnostics. This exists in .NET for the PC and lets me throw assertions in Release builds. I'm guessing that this is just something that's not a part of the silverlight toolkit. What is the correct way of enab...
I'm using silverlight for windows phone and I want to bind the IsEnabled property of a button to whether a textblock has text in it or not. In other words, I want my button to be enabled when the textblock's Text is not empty and disabled otherwise. Is it possible to do this purely in XAML using Styles/Setters/Triggers or any other mech...
I've only been able to find a couple of people online mentioning this, and it seems to be as simple for them as adding the service reference. However, when I attempt to add a service reference for my WCF service (which works correctly in a regular console app, so I have ruled the WCF out as the problem) I receive a host of errors. War...
Hi, I am writing an application which consists of a master "server" database (most probably sqlite) and a client side replica with client specific records (again, Sqlite). The clients may only be online occasionally or may be on slow 3G connections; I need a solution to reliably synchronise content either on demand or at scheduled inter...
Hi, I want to define control styles in a resource dictionary and use those for theming of Silverlight 4 and WPF 4 applications with as little adaption as possible. Thats why I need to know all differences between SL and WPF theming, so that most of the XAML will work on both platforms with little to no changes. The only difference tha...
In my SL4 app, I have a call to a service, svc.SubmitAsync(). Since this is an async call, once the method is hit, my code goes on to the next line. This is fine as long as the user enters the correct user name and password. If they don't, EndSubmit() throws an exception. EndSubmit() is in References.cs, part of the auto-generated Silver...

I have an existing application that has some parts of formatted text-blocks (standard formats such as bold, italic, unordered list, …) saved in the database.

I'd like to use the CSharpCodeProvider to create a Silverlight assembly and add fonts int it, but it seems that the CompilerParameters only support build as "embedded resource", which can not be use in the FontFamily Uri.

Is animation for custom properties of array type supported? Animation for simple properties (of Point type for example) works fine for me.

I'll also need to know... How would I load the XML into XElements from either? How would I save from an XElement into either? ...

For example, if one of the templates has a checkbox in it, I want the application using the control to be notified ...
I don't have much experience on the web services / database abstraction layer side of things for Silverlight, and am caught on an aspect of my porting effort. There was a core C# developer on the project that is no longer involved, and I'm working with code that he wrote. I'm updating code on a SL3 project with the RIA Services preview ...
