Using HTML 5 and the Web API for AJAX file uploads with image preview and a progress bar - .NET Development - Gal Ratner

AJAX file uploads used to be a client / server process in HTML 4. They required a round trip to a server side module, usually using an IFRAME and constant querying of the number of bytes uploaded, then reloading a progress bar inside the IFRAME with the current progress value. Luckily HTML 5 has a level 2 XMLHttpRequest object that natively support file uploads. This makes it a breeze to give your users a great experience when uploading files to your application. (more)

ASP.NET 4.5 and ASP.NET MVC 4 took an important step forward with the release of Visual Studio 2012. In addition to the new features and improved performance, the main direction seems to be bundling less namespaces in the core framework and more official libraries on NuGet. The main benefit of the new approach is the ability to update more code in an out-of-band release without being tied into the bi yearly .NET core release cycle. In other words: Microsoft and third party vendors can update releases ... (more)

ASP.NET MVC continues to innovate and in its current version (4) it offers support for Web APIs. Today we are going to examine a real life scenario of using Web APIs along with MVC 4 as we are utilizing the Google Earth plug-in to mark a defined area and SQL Server 2012 geography type to help us persist and calculate GIS data. In our example we are going to mark an area on the globe using a polygon, calculate the center of the area, find all of the coffee shops closest to the center of the area and arran... (more)

Reloading a Razor WebGrid after Ajax calls using a partial view - .NET Development - Gal Ratner
posted by galratnergalratner 539 days, 2 hours, 24 minutes ago
Friday, December 02, 2011 12:30:52 AM GMT
If you are using Razor and MVC you probably make some use of the built in controls in System.Web.Helpers. WebGrid, located in the Helpers assembly, was created for WebMatrix’s Razor Web Pages and landed itself nicely to Razor views in MVC. WebGrid, much like ASP.NET’s ListView control, is designed to display a data driven HTML table on the screen. It has support for paging, sorting and column customization. In this article, we will be taking a quick look at loading a WebGrid with data, both as a part o... (more)

Give your old ASP.NET validators a makeover with jQuery TOOLS - .NET Development - Gal Ratner
posted by galratnergalratner 562 days, 5 hours, 12 minutes ago
Tuesday, November 08, 2011 9:43:37 PM GMT
If you have been working with the default validators in ASP.NET for a while you are probably used to the plain old look they create on your page and while you can rework the way they look, ASP.NET validators are essentially a Label. They are unable to change the appearance of other elements or run scripts without a complete page postback. jQuery TOOLS is a jQuery based UI library you can find here. jQuery TOOLS contains a validator as a part of its form tools. The jQuery TOOLS validator is based on HT... (more)

The Bing API allows developers to query the Bing Engine.  Queries can be sent using JSON, XML or SOAP.  In order to query Bing you will need an Application ID available on the Bing Developer Center.  You will also need to agree to the terms of service. The Bing API includes support for Images, Answers, news, Phonebook, related, Spellcheck, Translation, Video and web results. In this example we will use the InstantAnswer SourceType in order to query for specific flight information. The InstantAnswer r... (more)

Keeping users passwords in your database is a part of almost every application, yet securing passwords is rarely being done correctly. I recently read an article by Coda Hale about the ineffectiveness of password salts. Coda Suggested using bcrypt to store passwords. He reasoned his argument by explaining bcrypt is extremely slow to compute, therefore making it slow to hack. I completely agree, however, I wanted to add another way of safely storing passwords in a more conventional way by hiding the s... (more)

System.Web.DataVisualization contains 34 types of charts. The most common of them is the Column chart on which I already blogged about in Display a sales chart with ASP.NET Chart control and Linq to SQL. Today I am going to take our sales chart one step further and display the top selling products for the year. Since we have multiple products for each time span, I chose a Bubble chart.

Sharing memory session between servers - .NET Development - Gal Ratner

Session variables hold per user information. Unlike cookies, sessions store information on the server rather than on the client. The client holds a session cookie with the client’s session ID and at the time of an HTTP request, the server accesses the client’s session ID and retrieves the session data. The default implementation of session has the web server holding the information in memory. This implementation as fast as it is has some drawbacks: Recycling your app pool or restarting IIS will abando... (more)

Spatial search is the process of searching locations nearby to a position in space.  A good example of a spatial search would be finding all of the restaurants near your present location. With Google’s Maps API and SQL Server’s Geography data types we can build a quick spatial search in no time. In this little exercise I will be detecting the user’s location, displaying it on a map and suggesting nearby restaurants. Since not all browsers support the W3C standards I will also allow manual input of the... (more)

There is some confusion out there about a simple question: How can I use Entity Framework? Some developers have heard about reverse engineering models so I decided to write a quick preview to the main features of EF4. This isn’t an in-depth article, but, rather a visual summary of the main four scenarios EF can accommodate.  If you are looking to utilize any of the scenarios described here you might need to seek further documentation and realize that development with Entity Framework is a vast subject an...

In email marketing, sending customized emails is a common practice. Emails containing special offers, shopping cart items or any other dynamic content, are usually tailored to the individual and are being sent either by request or as a part of a marketing campaign. This presents a challenge since email templates are usually being maintained by the marketing department and need to be simple to change, yet flexible enough for a programmer to add any dynamic data as needed. The solution can be reading a dyn... (more)

For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters. “ you are probably aware that there is no practical way of moving files with long paths using System.IO.File.

This is a single class, single file rolling file appender. Usage: To use this logger all you need to do is either add the class to your code or use the DLL as a reference. If you chose to use the dll you need to import it in your code as follows: using InvertedSoftware.PLogger.Provider; Then to write a log line you simply need to cal... (more)

A major part of any SOA implementation is the ability to return multiple data formats and while SOAP still plays a major role in SOA, the need for RSS syndication, JSON and plain XML may require you to add new functionality and steer away from traditional WCF RPC calls.
