DOWNLOAD ANYTHING!

I recently started learning about Open Social and thought will write some useful application for orkut and here is one. I have named it as GFinder. You can find almost any files (pdf,mp3,avi) using google.Here is how it works
Goto http://www.google.com
Song Name = intitle:”index.of”(mp3|mp4|avi) “way back into love”

eBook = intitle:”index.of”(chm|pdf|doc) “silverlight”

Using the above query in google will give you any files you want.This application does the same.You can add this application to your orkut. And no need to remember anything from above. Just query for anything and you will get it!.

Orkut application is still on sandbox.Once it’s aproved by orkut team I will share the link.

Next Business Day in SQL

The other day I found myself needing to come up with a way to calculate the next business day including taking into account holidays. A recursive function turned out to be just the thing to use.

Scripts
To start with, you’ll need to create a table to hold the holidays: It can be any table which has just Holiday Date in it.

CREATE TABLE [holiday] (
[holidayDate] [smalldatetime] NOT NULL ,
CONSTRAINT [PK_holidayDate] PRIMARY KEY CLUSTERED
(
[holidayDate]
)
)

The function is

SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO

GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO

If date is something like 24/04/2009 which is Friday and if Monday is specified as holiday in Holiday table. It will written 28/04/2009

Handling WCF Exceptions in Silverlight

As you know it’s not possible to handle WCF Exceptions on Silverlight side. As Silverlight plug in does not capture error thrown in 400-500 soap error range. It can only handle soap fault which are 200. So to handle any type of exceptions from WCF we need a work way round. We need to convert exception to 200 and use custom binding at Silverlight side. Here is the attached source code which will do the work for us. In Silverlight 2.0 we don’t have FaultException so attached module contain SLFaultException which can be used to pass custom error messages to silverlight side.

There are few changes required to adopt this to any silverlight application.
Add the following to Global.asax which is handling the job of converting fault service request to 200 so that silverlight plug in can handle it.

protected void Application_EndRequest(object sender, EventArgs e) {
if (HttpContext.Current.Request.PhysicalPath.EndsWith(".svc", StringComparison.OrdinalIgnoreCase) &&
HttpContext.Current.Response.StatusCode == 500 &&
!HttpContext.Current.Request.Browser.Crawler &&
HttpContext.Current.Request.Browser.EcmaScriptVersion.Major > 0) {
// Set 200 if its a faulted service request
HttpContext.Current.Response.StatusCode = 200;
}
}

and In app.xaml we need to register this new assembly

// Register faults
System.ServiceModel.SilverlightFaultMessageInspector.RegisterCurrentAssembly();

and please note the binding It’s a custom httpBinding

EndpointAddress address = new EndpointAddress("http://127.0.0.1:52620/Service.svc");
BasicHttpMessageInspectorBinding binding = new BasicHttpMessageInspectorBinding(new SilverlightFaultMessageInspector());
ServiceClient proxy = new ServiceClient(binding, address);

That’s it. Now Silverlight application can handle Fault Exceptions from WCF.
