Export MS SQL Database schema with C#
A few days ago I was searching for a way to export MS SQL schema of all databases of a server for backup and migration purposes. Although I found some tools, what I needed was a way to get stored procedures, functions, views, triggers and everything even if it was encrypted.

C#: Calculating all Greek Public Holidays for any given year
After calculating the Greek Orthodox Easter, it was time for the public holidays calculation. With the Easter calculation ready, it proved to be much easier than expected!
C#: Calculating Orthodox and Catholic Easter
Some time ago I was called about an online calendar for a company’s portal. The need was to inform employees about public holidays for the requested year. In Greece, some of those holidays are static meaning they occur the exact same date each year, but some are based on the Orthodox Easter so they move from date to date. There are a lot of online services that can return these information, but I thought I should give it a go and try writing the Orthodox Easter calculation in C#. Saying that, I found the algorithm online and since I was there I also found the Catholic Easter algorithm.
C#: Getting a user IP behind a proxy (HTTP_X_FORWARDED_FOR)
Did you know that HTTP_X_FORWARDED_FOR can return multiple IPs? According to http://en.wikipedia.org/wiki/X-Forwarded-For the format is:
X-Forwarded-For: client, proxy1, proxy2
SQL Server: How to simulate DROP TRIGGER IF EXISTS
I usually store triggers, store procedures, functions, queries etc in sql files in an SVN repository. I then use a simple app I wrote, that just opens each file and executes it. The problem of course is CREATE and ALTER. I can’t use CREATE because the same trigger might already be there. On the other hand I couldn’t use ALTER because some triggers might be new.
SQL Server: Using .NET assemblies (SQLCLR)
SQLCLR is a technology for hosting of the .NET CLR engine inside SQL Server. Adding an assembly can be a lifesaver sometimes, since the limitations of coding in TSQL stored procedures, triggers or functions are a lot and profound.
