Introduction to MVC In the last few years a software architecture changed very heavily. From desktop (forms) application which were very popular in Windows XP users move to SOA and now completely start using web based solution hosting in a cloud. Of course such evolution is not something bad, just the opposite in my opinion because web based application are highly scalable, better secured and available from each place in the Earth where user has an Internet connection. Such a big changes in software ...

Since SQL SERVER 2005 it is possible to store XML data in database by using dedicated data type - XML. This type solved many programming problems such storing XML data as simple text which was very unpleasant to maintenance  and detecting errors in document structure. Now stroring XML data is very simple and requires only the creation of column in XML data type. But sometimes we may want to do reverse operation. I mean generating XML document or fragment from non XML columns in a single SELECT statement....

When SQL Server 2008 and later SQL SERVER  2008 R2 occured the image datatypes coexists with several new and recomended by Mictosoft BLOB datatypes such varbinary(MAX). Let`s have a look: varbinary(max) /binary(n) variables store variable-length binary data of approximately n bytes, may store a maximum of 2 gigabytes.image variables store up to 2 gigabytes of data and are commonly used to store any type of data fi...

The other thing is that most of business solutions displays some data in tabular format knows as grids and grid has always one problem: number of records increasing in time. So we need to ask ourselves do we really need to display all the data together ...

To demonstrate how to start with the asynchronous operation in ASP.NET 4.5 I`ve created very simple solution which consist of ...
