Forget what I said earlier ... get this: http://www.jtleigh.com/people/colin/software/CopySourceAsHtml/ This is a much better solution. For example: public IQueryable < Property > SecuredProperties { get { IQueryable < Property > q; //if the user is an admin, bypass security if (_Service...

If you were like me and downloaded the CTP today, all anxious to give it a whirl, you probably found out like I did, that the credentials that the web page state to use DON'T WORK! The website says: VPC Credentials: Username: Administrator Password: P2ssw0rd ( NOTE: Microsoft strongly recommends...

If you have to work with mapping data to objects you know what a pain working with nulls has been historically. In the past, your database can deal with nulls very easy but your object model could not. As developers and architects, we would have to come up with “schemes” to deal with a null...

LINQ enables developers to query data sources directly out of code with a SQL like query language. You could write to get all customers out of a table. This new way of queries is only possible because of several new language features in C# 3.0, which Anders explained in his 75 min. session: Local Variable...

1) Beta 2 of Atlas/Ajax or whatever you wanna call it this week http://ajax.asp.net/ 2) .NET 3.0 Framework http://www.microsoft.com/downloads/details.aspx?FamilyId=10CC340B-F857-4A14-83F5-25634C3BF043&displaylang=en 3) The Visual Studio 2005 SP1 Beta http://connect.microsoft.com/VisualStudio/content...

After a killer presentation by ScottGu at North Dallas .Net User Group I finally got around to playing with LINQ and in particular the database portion of it known as DLINQ. After about 20 hours of "learning the ropes" over the weekend, I decided to show what I had figured out to some of my...

Problem 4 of Project Euler poses and impractical albeit intriguing problem: given all three digit numbers (100, 101, 102, ..., 998, 999), find the largest product of 2 of those numbers, where the product is a palindrome . For example, 580.085 is the product of two three-digit numbers (995 x 583) but...

The fifth problem at Project Euler proposes this nostalgic primary school exercise: find the smallest quantity that is evenly divisible by some numbers, the least common multiple of 1, 2, 3, ..., 20 to be precise. To begin with, let's remember the old arithmetic formula:   Where gcd is the greatest...
