Easy Database Driven Development with Boost and SOCI

October 21st, 2013

Last weekend I started to learn more about C++, my first project is a contacts manager, so I googled a little about how to do some persistence on C++ with minimum code and then I found SOCI.

SOCI is a very small database library which gives us the illusion to be embedding SQL queries in C++ code as the project site says, in fact, this is the beauty behind the library, which makes your C++ code very clean and easy to maintain.

But there’s no way to be productive with C++ programming these days without Boost, this awesome library has several utilities classes which can speedup your development several times, this blog post will show a little more about how these two libraries can help you to develop a database driven console application.

Using Autofac in a ASP.NET MVC 4 application

Fixing SelectedValue issue on DropbDownListFor with SelectList

July 30th, 2012

After spent several hours trying to figure out how the SelectedValue works on DropDownListFor, I finally figure out how to do it, you can also check my answer on stackoverflow here.

It’s very simple to get SelectList and SelectedValue working together, even if your property isn’t a simple object like a Int, String or a Double value.

Example:

Assuming our Region object is something like this:

1
2
3
4
public class Region {
     public Guid ID { get; set; }
     public string Name { get; set; }
}
