Resize image on the fly with ASP.NET MVC(www.leniel.net)

submitted by leniel(504) 1 month ago

I built a piece of code sometime ago to display image thumbnails in a listing page. I thought it's about time to optimize it. I refactored it and started using the WebImage class that comes in System.Web.Helpers namespace. With this class in place you can resize, crop, rotate, etc any image. There's no need to save the thumbnail in the disk, that is, a new image can be generated on the fly/dynamically and sent to the user’s browser. read more...

ResourceManager with an External Assembly DLL(www.leniel.net)

submitted by leniel(504) 5 months, 25 days ago

As a software developer I like to work with everything that is related to software Localization known as L10n. Besides being a developer working defining the architecture that will be adopted in a given project and doing the hard “FUN” work writing the code, I’m also a translator. One thing I've been trying to do recently is to be able to use localized strings that are present in an external assembly [ DLL ] using the ResourceManager object. Read on... read more...

Import/Export SQL Server database table data with SSMS(www.leniel.net)

submitted by leniel(504) 10 months, 2 days ago

This post is a visual guide about one of the most powerful features of Microsoft SQL Server Management Studio (SSMS) 2008: Import/Export database data. These tasks are useful for example when you need to debug an application with real world/production data to find possible bugs in your code. You can import the production database data to your local development database and find what’s causing problems. These tasks can be used to create a protection layer because you won’t be working “directly” with production data. read more...

Replacing Web.config settings with Transformations(www.leniel.net)

submitted by leniel(504) 11 months, 11 days ago

Let’s say you want to point to a different connection string when you deploy your ASP.NET Web Project to your hosting provider. Until recently you’d have to modify your Web.config file manually. This is an easy procedure but you might end screwing up the file in some way. Visual Studio 2010 comes with a great new feature called Web.config Transformation that allows you to perform transformations in whatever section of your Web.config file. read more...

There you can be sure that someone somewhere will help you to find an answer to your question. As a consequence I decided that I’ll try to give back and share a portion of the knowledge I acquired in these 7 years of programming experience. Read on... read more...

Upload/Import Download/Export any File to/from Oracle Database(www.leniel.net)

submitted by leniel(504) 2 years, 2 months ago

The general idea one have about databases is that they only serve the purpose of storing plain values as numbers, dates and text. A database does not do just that but even more allowing you to store a whole file as an Excel spreadsheet or an MP3 file in a column you define in your table. This post shows you how to Upload/Import Download/Export any File to/from Oracle Database through a simple ASP.NET MVC application UI. Have you ever heard about BLOB? This is what makes it possible to store a whole file in a database table. Read on... read more...

Translation @ a click with Babylon(www.leniel.net)

submitted by leniel(504) 2 years, 3 months ago

If you are not a native English speaker as is my case and if you work in the software world, chances are that you had to resort to any online dictionary to find the meaning of some word. English reigns when it comes to programming languages and any other sort of computer related stuff. With Babylon the translation from/to English to a varied set of languages is just @ a click of the mouse. This amazing software product has helped me a lot since I started the computer engineering course and I think it'll continue to play a big role in my English learning process during the years to come. It's practically impossible to work in the software industry without a grasp of English grammar, so that if you want to know a software product that can help you, read on. read more...

This post shows how to implement the Model View Presenter (MVP) pattern using Castle Project, which is an Inversion of Control Container framework. Employing Castle Project containers and ASP.NET it turns out to be a simple task to have a Web App that takes advantage of the MVP pattern. You'll see how to: use inversion of control (IoC), define a base presenter, define a base view, implement a view interface, implementing a view that inherits from the view interface, implement the presenter and put them together in an ASP.NET web application. read more...

A* pathfinding search in C# - Part 3(leniel.net)

submitted by leniel(504) 2 years, 5 months ago

This is the last installment in the series about A* search. The C# source code implemented is available in the final part of this post. As promised in the last words of A* pathfinding search in C# - Part 2 today we’re gonna run a test case using the Romania map. This post shows a test case in which the application outputs the shortest path from Arad to Bucharest. I used the ViewOtherPaths method to show the different possible routes. This way we can have a look at why the A* algorithm has chosen such shortest path. read more...
