Simple reusable clear form function in asp.net using jquery?

I ve created a function which clears the form without writing much javascript code.

$.fn.clearForm = function() {
return this.each(function() {
    var type = this.type, tag = this.tagName.toLowerCase();
    if (tag == 'form') {
        $('td.status', this).empty();
        return $(':input', this).clearForm();
    }
    if (type == 'text' || type == 'password' || tag == 'textarea' || tag ==
                                 'label')
        this.value = '';
    else if (type == 'checkbox' )
        this.checked = false;
    else if (tag == 'select')
        this.selectedIndex = -1;

});
};

and just call this as,

function clearaddform() {
    $("#aspnetForm").clearForm();
  }

and now you can just call clearaddform function from your button. 

The Twitter hack: how it started and how it worked

  I was shocked while i was going through this article about the Twitter Hack. It is still unbelievable that twitter has been hacked just due to XSS  "cross-site scripting". 

[Fluent nHibernate vs Entity framework] Which to choose for ORM?

 I ve been working with Fluent nHibernate and it ships really well with my asp.net mvc web application pretty well. Just yesterday had a look at Microsoft's Entity Framework and it looks like a good competitor for fluent nhibernate.. I was searching through the web and i found this wonderful article,

What is a “web service” in plain english?

I've been reading about "web services" here on SO, on Wikipedia, Google, etc and I don't quite understand what they are. What is the plain english definition/description?

If I make a simple website using PHP that just, say, prints a random integer to the page... is this a "web service"? If not, why not?

A simple definition: A web service is a function that can be accessed by other programs over the web (Http). To clarify a bit, when you create a website in PHP that outputs HTML its target is the browser and by extension the human being reading the page in the browser. A web service is not targeted at humans but rather at other programs.

So your PHP site that generates a random integer could be a web service if it outputs the integer in a format that may be consumed by another program. It might be in an XML format or another format, as long as other programs can understand the output.

The full definition is obviously more complex but you asked for plain English.

What is cool about c# generics, why use them?

I thought I'd offer this softball to whomever would like to hit it out of the park. What are generics, what are the advantages of generics, why, where, how should I use them?

• Allows you to write code/use library methods which are type-safe, i.e. a List<string> is guaranteed to be a list of strings.
• As a result of generics being used the compiler can perform compile-time checks on code for type safety, i.e. are you trying to put an int into that list of strings? Using an ArrayList would cause that to be a less transparent runtime error.
• Faster than using objects as it either avoids boxing/unboxing (where .net has to convert value types to reference types or vice-versa) or casting from objects to the required reference type.
• Allows you to write code which is applicable to many types with the same underlying behaviour, i.e. a Dictionary<string, int> uses the same underlying code as a Dictionary<DateTime, double>; using generics, the framework team only had to write one piece of code to achieve both results with the aforementioned advantages too.

What's your choice for your next ASP.NET project: WebForms or MVC?

Let's say that you will start a new Asp.Net web site/application tomorrow. What your choice between WebForms and MVC, and why?

I'd choose asp.net MVC for the following reasons:

1. ASP.NET MVC has borrowed so much from Rails that it feels like a direct port in some ways (and that's a good thing in my mind).
2. AJAX is important, but I hate the Microsoft "Atlas" approach to AJAX (whatever the product name is these days). If you're going to do AJAX, you need to understand the HTML and the JavaScript. Frameworks that hide that from you are hurting you more than they are helping you (IMO).
3. JQuery has taken over the world it seems in terms of JavaScript frameworks. ASP.net MVC is well-integrated with it. I want to learn it, so there's great alignment here.
4. The whole "control" model is a neat idea, but it is more complicated than it appears on the surface. For example, look around on SO for questions about how a UserControl can find its highest level containing control and so forth. The control hierarchy abstraction has leaks in it. Grids are great if they do what you want out of the box, but it's very very hard to customize them to do something they weren't made to do. And the best grid controls on the market (the ones that are highly customizable) are large, bloated, overly complicated beasts. Maybe that shows us that we should drop back down to HTML and let loops in our views do that kind of thing for us.
5. I believe I can build complete, beautiful apps in ASP.net MVC much faster than in ASP.Net (and I've got some years of ASP.Net under my belt). Look at StackOverflow ... built quickly on ASPMVC with JQuery, and it's fast, scalable and a joy to use IMO.
6. Oh, and it's completely open source! It is ok to read the source code, blog about it, and even modify then redistribute it!

So be wise in choosing it...

Latitude and Longitude Lookup with jQuery, C#, ASP.NET MVC

This asp.net mvc controller action returns a place latitude and longitude based on zipcode and country name,

public ActionResult LookupCoordinates(string Zip, string Country)
{
    string Lat = "";
    string Lon = "";
    string PostUrl = "http://ws.geonames.org/postalCodeSearch?postalcode=" + Zip + "&maxRows=10&country=" + Country;
    WebResponse webResponse = webRequest.GetResponse();
    if (webResponse == null)
    { }
    else
    {
        StreamReader sr = new StreamReader(webResponse.GetResponseStream());
        string Result = sr.ReadToEnd().Trim();
        if (Result != "")
        {
            // Load the response into an XML doc
            XmlDocument xdoc = new XmlDocument();
            xdoc.LoadXml(Result);
            //  Navigate to latitude node
            XmlNodeList name = xdoc.GetElementsByTagName("lat");
            if (name.Count > 0)
            {
                Lat = name[0].InnerText;
            }
            //  Navigate to longitude node
            name = xdoc.GetElementsByTagName("lng");
            if (name.Count > 0)
            {
                 Lon = name[0].InnerText;
            }
        }
    }
    return Json(Lat + "," + Lon);
}

and the jquery function for implementing this would be,

function LookupCoordinates(zip) {
        $.post("/Home/LookupCoordinates",
        { Zip: zip, Country: "US" },
        function(data) {
            var result = eval('(' + data + ')');
            var coordinates = result.split(",");
            $("#Lat").val(coordinates[0]);
            $("#Lon").val(coordinates[1]);
        });
    }

Images in asp.net performance booster web config setting...

If your asp.net website deals with images just do this in your web.config file and see the performance and no drawbacks of doing this.

Under system.webServer in web.config set for example

<caching>
            <profiles>
                <add extension=".png" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange" location="Any" />
                <add extension=".jpg" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange" location="Any" />
                <add extension=".gif" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange" location="Any" />
            </profiles>
        </caching>
