I have created an ASP.NET page to automate the Microsoft Source Code Analyzer for SQL Injection command line tool. It would be tedious to craft a command for every page in a large Classic ASP web site. I was unable to scan my entire site until I developed this ASP.NET page.

You can customize the design of a web service's test page with a single line of code in the web.config file. But like most things in ASP.NET it is not that easy if you actually try it!

Yesterday I added a progress bar to my ASP.NET page for downloading YouTube videos. There was no visual indication that the download was taking place because the page just appeared to be taking a long time to load. I would have to open the download file location to verify that something was being downloaded.

Last evening I tried out two of the tools that Joe Stagner wrote about in his blog post Tools to block and eradicate SQL injection. Since I manage a classic ASP web application that was completely lacking in security and potentially vulnerable to these attacks, I thought I'd share my experiences.

Currently I'm using ASP.NET in an unconventional manner to write scripts that download files. Asynchronous tasks and the WebClient object's DownloadFile method are proving to be a very convenient combination of features which makes it easy to automate the process of downloading a lot of files. 

I have found a random PHP script for creating captcha images using the GD Library and I've converted it to C# as promised in my previous blog post. I learned something new on this project. The first color in a new image will be the background color but only if the image is not using TrueColor.

There is a PHP script on A List Apart for dynamically generating images for paragraph headings using fonts. I have successfully translated this script into C#.

I've been exploring asynchronous operations in ASP.NET 2.0 and while I don't have anything original to contribute you might find how I used this technique interesting. Even when the code is well documented it can be useful to know how it might be applicable to a specific problem.
