How to prevent SQL injections
Many applications include code that looks like: 1: string sqlStmt = "SELECT * FROM USERS WHERE UserName= '" + un + "' AND Password='" + pwd + "'" ; Admit it...it's ugly, but you constructed SQL statements like this one. The variables un,pwd are provided by the user. The problem with this SQL string is that the attacker can piggyback SQL statements in one of them. What if the attacker enters this: un = maor, pwd = 123456' OR 1=1 . The following...

ASP.NET 2.0 - Web Site vs Web Application project
This post was migrated. You can read it at http://blog.maordavid.com/2007/06/aspnet-20-web-site-vs-web-application-project/   A common question by asp.net developers is what project model should I use for asp.net application? Web Site project (which introduced with VS 2005) or Web Application project (which delivered as add-in for VS 2005 and built-in within VS 2005 SP1)? There is no thumb rule.

It is a clean approach to associate metadata with program elements and later...

Interface vs Abstract Class
I frequently asked what is the difference between Interface and Abstract classes. The main difficulty is the choice of whether to design your functionality as an interface or an abstract class. Interface An interface is a reference type containing only abstract members. These can be events, indexers, methods or properties, but only the member declarations.
