• Slow performance of System.Math library in .NET4/VS2010

  - by Niranjan

  My application compiled in .NET 4 seems to be performing really slow compared to .NET 3.5. When I did the performance analysis, I found out that the System.Math libraries in VS2010/.NET 4 have slowed down considerably. Any explanation to this? Has anyone else come across this or am I the only one seeing this? Thanks, Niranjan

• Role of "Refactoring" in good programming pratices?

  - by Niranjan Kala

  I have learned in Agile Development that: Refactoring is the process of clarifying and simplifying the design of existing code, without changing its behavior. I have heard about some GUI refactoring tools like resharper and DevExpress Refactor Pro! Here is my Questions: Question 1: how does it takes place in the Software development process and How far it effects the system? Question 2: Is Refactoring using these tools really fast the process of development/ maintenance?

• How to develop "Client script library" for ASP.net controls and how do these work?

  - by Niranjan Kala

  I have been working on .Net platform for 2 years and right now I am working on DevExpress controls for 6 months. All these control have client-side Events which are under some ClientScript nameSpace of particular control, Which specify ClientInstanceName, methods and properties accessible at client side. For example Button1 is ClientInstanceName and Button1.Text is a property, with methods like these: Button1.SetValue(); Button1.GetValue(); In ASP.Net Controls, buttons have the ClientClick event that fires before the Server Side Click event. I have inspected and goggled to extend client side functionality in asp.net controls. For example: create a ClientInstanceName property for controls or CheckedChanged event for CheckBox / RadioButton control. I have tried using these MSDN articles: Injecting Client-Side Script from an ASP.NET Server Control Working with Client-Side Script I got much information and ideas from these articles on how to implement/extend these. All are working in the client side. protected override void AddAttributesToRender(HtmlTextWriter writer) { base.AddAttributesToRender(writer); string script = @"return confirm(""%%POPUP_MESSAGE%%"");"; script = script.Replace("%%POPUP_MESSAGE%%", this.PopupMessage.Replace("\"", "\\\"")); writer.AddAttribute(HtmlTextWriterAttribute.Onclick, script); } Here It is just setting up attribute to the button. but all client side interaction no control from server. Here is that I want to know: How can I implement such functionality to create methods, properties etc. on client side. For example I am creating a PopControl as in the above code snippet same behavior as like Ajax ModalPopupExtender That have OK Button related properties. Ajax Controls can be directed to perform work from server side code e.g. Popup1.show(); How can I do this with such client enabled controls implemented controls as windows do? I am learning creation of Ajax Controls but I do not want to use ScriptManager or depend on another control. Just some extension to standard controls. I am expecting for ideas and implementation methods for such functionality.

• Are there any GUI or user interface design patterns? [closed]

  - by Niranjan Kala

  I was curious about GUI design patterns, so I searched and got some information, including a list of UI patterns for the web. This UI patterns website says that: UI Patterns is a growing collection of User Interface Design Principles and User Interface Usability Patterns present on web applications and sites today. Are there any other design patterns for constructing websites or other user interfaces? Are there any books that describe these patterns? I'm particularly interested in patterns for Windows desktop development and web development in the .NET platform.

• Running log operation in Http Modules?

  - by Niranjan

  Hi, I have a simple requirement in which I want to execute a long running application program on server (e.g. DTSX) I want to make an HTTP module for this, But I have a question whether the DTSX will run even if the user closes the page and browser. In my case user hits the handler with a query string but what if the user closes the browser immediately? How is the behavior different from simple linear page processing? I want my DTSX package to finish once its started no matter how much time it takes and also dont want to halt the user that is why I am using http modules in place of linear asp page processing. Reagrds, Niranjan

• If an Excel row contains particular words, return that row, highlight that row, or give Y/N for that row

  - by NIranjan

  I have a sheet containing thousands of cells in a column. These cell contains names of different securities. Some names of these securities contains a particular string such as "C/O". How can I use a formula that will return the rows that have these characters? EG. S&P 500 C/O 30/03/12 1380 MICROSOFT C/O 19/05/12 32 QUICKSILVER C/O 17/03/12 9 There is no consistency (can't use left/right/mid formula). Requirement : I want the formula which will return "C/O" in the other cell if this particular cell contains it.

• invalid token error while parsing an XML file with UTF-8 encoding

  - by Niranjan

  invalid token error while parsing an XML file with UTF-8 encoding. This error is coming when it encountered extended ASCII character 'â' { "â", "â" }. When I have changed the encoding from UTF-8 to ISO-8859-1 the parsing is successful. But my application should support UTF-8, ASCII and extended ASCII characters. What should I do for this? Any ideas are welcome. Thanks in Advance for your time and solution.
