Does using web services to expose a .NET DAL add security?
Currently my employer deploys a web application over 3 servers. DB - No public route Web Service DAL - No public route Web Server - Public route The reason for this is the theory that if the web server is compromised, they don't arrive at the DB directly, but instead arrive at the DAL box. To my mind, as the DAL box and Web Sever bo...

The program has to calculate pi until the user presses a key, at which point the thread is aborted, the result returned to the main thread and printed in the console. Simple enough, right?

.NET How would I build a DAL to meet my requirments?
Assuming that I must deploy an asp.net app over the following 3 servers: 1) DB - not public 2) 'middle' - not public 3) Web server - public I am not allowed to connect from the web server to the DB directly.

How to use reflection to get a default constructor?
I am writing a library that generates derived classes of abstract classes dynamically at runtime. The constructor of the derived class needs a MethodInfo of the base class constructor so that it can invoke it. However, for some reason Type.GetConstructor() returns null.

I also tried: Size iconSize = SystemInformation....
