How to fix "Sys is undefined" error ?

Recently I have faced a strange issue in the process of developing a task using script manager for async post backs.

The error is "webresource.axd and scriptresource.axd 404 not found" whenever I do any async call I use to get this error "sys is not defined". I have tried a lot to fix this issue by following the below links.

1. http://blogs.msdn.com/b/carloc/archive/2008/12/04/webresource-axd-or-scriptresource-axd-not-working.aspx
2. http://imnettellect.blogspot.in/2010/12/iis-75-webresourceaxd-and.html
3. http://stackoverflow.com/questions/1433512/asp-net-web-application-webresource-axd-and-scriptresource-axd-files-loading

and so on ....



After spending 4 hours I found a new property on asp.net 4.0 called EnableCdn that basically, if it's set to "true", it loads the resources from the Microsoft content resource servers.

Refer this link for information about EnableCDN.

This worked like a charm and fixed my issue.

I hope this snippet can help many techies. :-)

We may face a scenario to export the data of custom class object to excel using InterOp .You can get the property name's from the class object using Reflection.Create a work sheet header by reading the each propety of the class object.I have created a separate method to get the all properties into a list collection of string as given below         ///         /// Get the list of Properties Name into a list collection.         ///         ///         ///         public List GetPropeties(Employee objEmployee)         {             Type myType = objEmployee.GetType();             IList props = new List (myType.GetProperties());             List lstPropertiesNames = new List ();             foreach (PropertyInfo prop in props)             {                 lstPropertiesNames.Add(prop.Name);             }             return lstPropertiesNames;         } We need to call this method to create the worksheet header's as given beloe                 List lstProperties = GetPropet

Why Dispose() is preferred than Finalize() for Un-Managed Resources in .NET?

Image
Memory management is very important in any application development.The Garbage collector of .NET does almost all clean up activity for your objects.For unmanaged resources (Ex:Windows API created objects, File, Database connection objects, COM objects, etc.) are outside the scope of .NET framework. Why Dispose() is preferred than Finalize() If we use the " Finalize() " method,the  Garbage collector has to make two round in order to remove the objects. For an instance ,let me explain clearly if we have two objects as Object1 and Object2 and we finalize the Object2 as given in the below image.The GC has to categorize the two objects and put the Finalize objects into Finalization Queue.The GC will clean the object1 which doesn't use the Finalize() method and process the second round of cleaning the Finalization Queue. Now at this the " Dispose() " method will come into picture.This method belongs to IDisposable() interface .So the best practise to rele
