As TomTom123 has mentioned in this post:


How can we inform the client if the Stream has successfully been uploaded? The standard Callback process doesn't seem working.

Basic Instincts: Implementing Callback Notifications Using Delegates


Delegates are a critical aspect of the Microsoft® . NET Framework and are required learning for many programmers. They will take some time to master, but once you learn how to program with delegates, you'll be thrilled with the possibilities they offer.

Implementing Continuous Scrolling UI Pattern in ASP.NET

When you have numerous records to show, we have to resort to Paging. There is a better alternative to display voluminous data (especially read only data) while providing a better user experience & also making efficient use of server bandwidth - the Continuous Scrolling or Infinite Scrolling UI Pattern. Read on to know more about how to implement Continuous Scrolling UI Pattern in ASP.NET with a GridView.

Coroutines: Implementing Coroutines for .NET by Wrapping the Unmanaged Fiber API


Coroutines are a powerful feature of many programming languages including CLU, Scheme, Python, Ruby, and ICON. Coroutines can save processor overhead and reduce redundancy because they allow you to stop execution of a procedure midstream, return a value, and resume exactly where the procedure left off.This article shows how coroutines can be implemented for the .NET Framework by using the Fiber API and Managed Extensions for C++, and how they can be easily used with other .NET-compliant languages. This article also shows a sophisticated use of the runtime host for running multiple managed threads on a single OS thread.

Basic Instincts: Implementing Callbacks with a Multicast Delegate


This month's column is a follow-up to the December 2002 installment in which I introduced the basic concepts and programming techniques associated with delegates. I am going to assume you have already read that column and that you are familiar with the fundamentals of programming delegates.

C++ and STL: Take Advantage of STL Algorithms by Implementing a Custom Iterator


There are many benefits to using the Standard Template Library (STL) for C++ development, including the ability to use generic data structures and algorithms. To use the STL algorithms, an STL-conforming container is required. Iterating through the Internet Explorer cache is an informative exercise, but the cache is not an STL-conforming container. So, to use the STL algorithms to search and enumerate the Internet Explorer cache, an adapter is needed. Building such an adapter-an STL-conforming iterator-is the topic of this article. Also provided is an overview of the components of the STL and the Win32 Internet APIs used.

implementing a search similar to what you have in google when you type in a word


Dear all;

I have a textbox and what I would like to implement is basically a situation similar to what you have in google when you type in a word. In otherwords,

in the textbox when you type in J, it should generate a list of names that starts with O in alphabetical order, then next when you type in o, so that now you have Jo, it should generate a list of names instead that now starts with Jo in alphabetical order, then again when you type in h, it should generate a list of names that starts with Joh and so on. A sample code could be helpful. Thank you. No Javascript of Jquery please. All help will be greatly appreciated.

Looking for a simple Service and Console Client REST sample implementing BASIC authentication


Does anyone know of a C# code sample demonstrating WCF REST services and console test client with OperationContracts (GET and POST) implementing mutiple paramaters using BASIC authentication? Also, perhaps, using Fiddler as a test client as well? I have searched high and low for something like this, but have not had any success.

How to CATCH "Invalid postback or callback argument" exception?



How can I catch this exception? I do not want it to stop my page execution. Can/Should I do that?

Server Error in '/' Application.
Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Implementing a custom Membership Provider vs. using aspnet_Profile table - Which should I do?


I wanted to expand the amount of information that is associated with each user(MembershipUser) in the ASPNETDB.MDF database file. Adding columns like FirstName, LastName, etc. So I began implementing my own custom Membership Provider. I created a derived MembershipUser class with the extra private variables that I wanted each MembershipUser record to store. Its basically done. Almost after I did this I stumbled across the columns in the ASPNETDB.MDF->aspnet_Profile table called "PropertyNames" and "PropertyValuesString".  Could I have simply used these two columns to accomplish what I was attempting to do or are these columns for global application configuration settings?  

Is the aspnet_Profile table purpose to store expanded/related information about users such as personal information? Or is it for something else? Thanks.

How to send parameters to the AJAX callback function

Callback has separate session


Hi, I am using uploadify to upload files to the server. After the user selects one image, a callback is issued and the image is stored to the server. To track which images are saved, I stored each item in a generic list and later store that list inside a session variable.

The problem is, the callback has a different session then the page where I will be posting back to parse the session variable.

My question is why do callbacks have different sessions then the underlying page that issued the callback.
