I am still trying to solve the issue of displaying an image on a website without having the image external. As the data: scheme does not work on older browsers or big images, I'm currently experimenting with Silverlight. I managed to solve the embedding by Base64 Encoding the Image and passing it in using the InitParams, but actually I ...

I am surprised I could not find this question already asked, so if I simply missed it please notify promptly.

Silverlight's sandbox model will not work - it has to be a full-on downloaded, installed exe...
I am writing a Wix installer to install .NET assemblies to the GAC. Easy... My question is: is it possible to future proof this scenario so that I can pull ANY assemblies found in an existing network folder and register each of them - without having to hardcode the exact assembly names? This would allow me to create a single MSI that co...

I've got a single statement running on a ASP.NET page that takes a long time (by long I mean 100ms, which is too long if I want this page to be lightning fast) , and I don't care when it executes as long as executes. What is the best (and hopefully easiest) way to accomplish this? ...
I'm looking to implement a function with a signature something like the following: bool IsTimeZoneValid(string countryCode, DateTime localTime); The intention is to determine whether the country has a time zone in which the local time would be valid, given that we know the current UTC time. Let's say, for the sake of argument, that "v...
As when using any other class or third party libraries, one would expect exceptions to be documented as well, so I've always found somewhat redundant to add text descriptions to them. Are they really necessary? What are your thoughts? Thanks in advance. ...
In C# can you make a class visible only within it's own namespace without living in a different assembly ? This seems useful for typical helper classes that shouldn't be used elsewhere. (i.e. what java calls package private classes) ...

A confusing title I know. Let me explain. I have to marshal an array of structs, which then get converted to an array of classes (legacy compatibility). For instance public class InnerClass {} public class OuterClass { private InnerClass[] innerClasses; } public struct InnerStruct { // Data } private static buildInnerClass( Inne...
DateTime's formatting has some overlap between it'a standard date and time formatting strings and some of it's custom format specifier by them selves.

Hello, I've got the common situation where I've got user input that uses a subset of HTML (input with tinyMCE). I need to have some server-side protection against XSS attacks and am looking for a well-tested tool that people are using to do this. On the PHP side I'm seeing lots of libraries like HTMLPurifier that do the job, but I can'...
Here's the scenario (which uses a BindingSource bound to a DataTable within a DataSet): A user creates a new address book contact, fills in the First and Last name in data-bound controls. He presses Apply, whose event handler calls BindingSource.EndEdit(). He then realizes there was a mistake, and adds an email address. But when he pre...
