ASP.NET MVC Tip #1

Simple :

RedirectToAction("Index", "Home");

With Query String :  

RedirectToAction("Index", "Home", new { id = 22 });

JSON is another format of expressing data, just like XML. But, JSON is very simpler than XML, and tiny than XML.

Here is a simple example for JSON serialization in ASP.NET .

public class SpotFields
{
    public SpotFields()
    {
    }
    public int ID { get; set; }
    public int ProductID { get; set; }
    public int X { get; set; }
    public int Y { get; set; }
 
    public int X2 { get; set; }
    public int Y2 { get; set; }
 
    public int W { get; set; }
    public int H { get; set; }
    public string SKU { get; set; }
    public string Discription { get; set; }
 
    public string ProductName { get; set; }
    public string ImageName { get; set; }
    public string SeoName { get; set; }
}

Microsoft has bought Skype for a whopping $8.5 billion in cash.  Few days back there was news about Skype going on sale.

In a BBC interview, Gates said he advocated for the Skype acquisition. Surprise! Did you expect Gates to say that he hated the Skype purchase and that it was too pricey?

In the BBC chat, Gates said video conferencing will improve. He’s alluding to the fact that video phones will be common—you could argue that they are today via tablets and Skype.

Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your asp.net application, such as a cross-site scripting attack. You can disable ( Asp.net 2.0 ) request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. In ASP.Net 4 Please use below configuration

In the web.config file, within the <system.web> tags, insert the httpRuntime element with the attribute requestValidationMode=”2.0″.

Example:

<configuration>
<system.web>
<httpRuntime requestValidationMode=”2.0″ />
</system.web>
</configuration>

Step 2

<configuration>

        <rule name="Redirect to WWW" stopProcessing="true">
          <match url=".*" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^my-domain-name.com$" />
          </conditions>
          <action type="Redirect" url="http://www.my-domain-name.com/{R:0}"
               redirectType="Permanent" />
        </rule>
