Build Your Own Analysis Services Cache-Warmer in Integration Services

Cache-warming is one of the most neglected performance-tuning techniques for Analysis Services: perhaps it seems too much like cheating? Yet almost everyone knows how much difference there can be executing a query on a cold cache and a warm cache so there should be no excuse not to be doing it, especially if you know what queries your users are likely to be running in advance. AS2005's caching mechanism is more complex than I can describe here (or than I can describe full stop - although I hear ...

The Power of SQL CASE Statements

As developers creating data-driven Web applications, we've all written more than our fair share of SQL statements. If I had a nickel for every SELECT statement or UPDATE statement I've written in my six years as a Web developer, I'd be a rich man. Despite the familiarity with SQL that many Web developers have, one of the lesser known SQL tools is the CASE statement. The CASE statement is a wily little fellow that can be added to both the SELECT portion of a SELECT statement as well as the ORDER ...

Really Simple Syndication (RSS) is a common XML standard for syndaicating web content. It is typically used by content-producing sites to offer a machine-readable version of the latest headlines. For example, news sites like CNN.com and MSNBC.com offer RSS feeds for breaking news; most blog software includes RSS support that syndicates the blogger's most recent posts. Since its inception, RSS has radically increased in popularity; today it is hard to find a content-producing website that does no...

Caching Data for Better Performance

In every site or web-based application there is some data that doesn’t change very often, which is requested very frequently by a lot of end users. Examples are the list of article categories, or the e-store’s product categories and product items, the list of countries and states, and so on. The most common solution to increase the performance of your site is to implement a caching system for that type of data, so that once the data is retrieved from the data store once, it will be kept in memor...

ASP.NET Validators Unclouded

It makes no difference what kind of development you are working on, user input validation is always an important and often troublesome issue.What data needs to be validated? What are the valid conditions? Do we need to report every error in one pass or allow the user to correct one error at a time? Do we validate on the client or on the server? The questions go on.
Worse than that, the code can quickly get unmanageable, especially where we try to validate everything in one pass. Nested ifs, d...

A while ago I started working on converting an eCommerce payment gateway's (DataCash) COM server to a native .NET assembly using their XML API. Once I had got a basic version working I decided to produce a simple web form to test it out, and so opened it up for all comers (and received some very generous donations from CP members -- thanks guys :). As part of this web form I wanted to include support to check that users had entered a card number, expiration date etc., and then wanted to extend i...

It's been a long time since the original was posted, and I've promised this updated version of the article for some time, it feels good to finally get it off my chest.The control was originally borne out of a different project I was working on - building a native .NET interface to DataCash's payment gateway service - I built a test page and decided it would also be nice to have some simple credit card number v...

The motivation for this article lies at Self Validating ASP.NET Text Box by Patrick Meyer of NASA in Mission Planning Systems. Please read this excellent article for the self-validating control first. Like many other .NET developers, I like self-validating controls due to their simplicity. Microsoft provides CompareValidator and it serves the same purpose in general. Through self-validating control, I have to do less typing and there are less controls on the web form. This article validates the ...

ASP.NET validators are a great time saver. However, they lack the built in ability to validate multiple controls on the client side. Luckily, this is easily fixed.This requires that the user fills in the Phone field. What if you have a Phone field and an Email field. You could require both fields, but you might want to allow the user to enter only one of these fields. In this case, you couldn't use RequiredFieldValidator....

In this scheme the user is asked to enter an activation code which is obtained after purchasing the software. This activation process then allows the user to continue using the software or it may unlock some features that the user needs. A sample application allowing you to create an activation number will be created. A second application will then accept and validate the activatio...

Validating user input is a common scenario in a Web-based application. For production applications, developers often end up spending a lot more time and code on this task than we would like. In building the ASP.NET page framework, it was important to try and make the task of validating input a lot easer than it has been in the past. In HTML 3.2, validating data is a difficult process. Each time you get a request, you need to write code to check the input and write any errors the user has made ba...

In this article, we are going to use validation controls provided by ASP .NET in order to force the user to input correct information. You can enable validation of user input by adding validation controls to your form as you would other server controls. There are controls for different types of validation, such as range checking, pattern matching, comparison to a value or required entry. More than that, you can define your own controls for checking user's entry using validation logic that you wr...
