Validating ASP.NET checkbox (and similar) controls.


blog.dmbcllc.com There are controls in the .NET framework that can not be wired to the standard validation controls. The checkbox control is one example. You can’t use the requiredfieldvalidator because it has a value. It’s either true or false. And you can’t provide a regularexpressionvalidator or one of the others because it is a boolean value. So, if I want to make sure a check box is checked before the user continues, for example. And, I want to make sure that the error message shows up in the error summary control like every other error, how do I do that?

How to generate a random number sequence that is non-repeating in visual basic .net ?

I am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can’t find a way to generate a random number sequence in visual basic 9 .net

I found many examples in visual basic .net but the conversion doesn’t work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.

Thanks.

Optimizing Your ASP.Net Pages for Faster Loading and Better Performance.

If you read the internet and all of the websites dedicated to Asp.Net you will inevitably read about the wonders of the DataGrid, DataList, and Repeater controls. While each of these has its place, if you are only displaying data there is a much faster and more efficient means to do so.

Let’s say you have a page that displays articles based on a query string. Take my article pages for instance. Each article is stored in a database and displayed on the page based on the unique id of the article as stored in the database.

A normal asp page execution procedure goes something like this. The code queries the database based on the Article I.D. and then brings back that information to the page where you display it in the fashion that you would like. This is a fairly straight forward approach with asp and is done all the time.

So how do we speed up our asp.net pages?

Number 1: Use Asp.Net Caching!

This is a no-brainer, and I won’t go into the brilliance or details of asp.net caching here because at the time of this writing Google has 2,780,000 articles on the topic. Basically instead of querying the database each time the page is loaded you only query the database once and load that result into the system cache. Subsequent calls to load the page retrieve the data from the cache as opposed to the database which gives you an instant and considerable performance boost. You can then set the cache for how long the cache should store the information as well as many other features. If you are not using the cache, you should be whenever possible!

Number 2: If possible, do NOT use the standard Asp.Net controls.

That’s right. The standard asp.net controls are designed for rapid development and not page performance. They allow you to design pages that grab and display data very quickly but their actual performance suffers because of the extra overhead which is there for ease and speed of development time and not page execution speed.

Advantages of Application Servers in Web and Software Development

An application server is a server that hosts an application program to provide business logic for third-party application program. An application server combining or working with a web server is called a web application server in many usages. A web application server can be a flexible web application development and deployment tool.

The application server is frequently observed as a part of a three tier application, which comprises of a GUI (graphical user interface) server, business logic or application server and a database server. In a more descriptive way it can be viewed as:

  • Front end or first tier (personal computer)
  • A middle tier (an intranet server or LAN)
  • Third tier or back-end (database server)

Advantages of Application Servers in the Web and Software Development Scenario

In the web & software development scenario, an application server offers various advantages including:
