Even though I don't program with C++ much these days, I still love the book entitled 'C++ Programming Language'

There is a preview version only, but the release version will come soon, I think it looks very promising.

Although there is a built-in control for advertisement rotation in ASP.NET, it is capable of showing image ads only. However, in the real life you often have to deal with the ads that require some JavaScript code, for instance, you want to put there AdSense code or want to use Flash banners instead of images. Thus, if you want to rotate complex ads, you have to develop your own control.

Having read a great variety of forum and blog posts, I met a lot of misconceptions about ASP.NET that definitely made people to turn away from ASP.NET. I won't argue whether ASP.NET is better than PHP (or Ruby on Rails) or not, instead I'll try to bust those myths.

I want to proceed with telling how to deal with uploaded images with ASP.NET. I have already showed how to resize images. However, that resizing method isn't perfect. It doesn't produce images of high quality.

In the previous tutorial I showed how to handle image uploads, how to validate some things and finally how to resize images retaining their proportions. This time I'll show you how to prevent uploading of files which size exceeds the defined limit.

Annoying crash

Is image uploading different from simply file uploading? No, but when creating an image uploading functionality you usually have to perform more operation, than if you application were to receive text files only.

As you may already know, it is required to create a web service to make use of some ASP.NET AJAX Control Toolkit controls. However, you can use static methods of your pages instead, you just have to mark them with the System.Web.Services.WebMethod attribute and not set the ServicePath parameter in the ACT controls.

This story is not a debate on "ASP.NET vs PHP", but this story is about the people who develop their web applications with PHP, but pretend that they are using ASP.NET. Yes, such people do really exist. I came across their posts in the forums, where they said that or asked how to change the extension of PHP scripts to .aspx.
