VB.NET's yield return

I was struggling with an issue today when converting some C# to VB.NET. C# has a really cool yield return statement that is used in an iterator block to provide a value to the enumerator object. VB.NET does not have the yield keyword. So, there are a few solutions (none of which are really clean) to get around this. You could use a return statement to return the value if you are looping through and would like to break an enumerator and return a single value. However, if you’d like to return the entire enumeration, create a List() of the child type and return the list. Since you are usually using this with an IEnumerable, the List() will work nice.

Writing a Base64 String to the File System or Browser

Quite often, vendors pass images or PDFs to customers using the binary contents of the file. To make it more secure, they convert the binary contents to a Base64 string.

First, you must convert the data into a Byte array. The sample code below demonstrates this:

Visual Studio 2008 Web Service Issue

I discovered an issue in VS 2008 Beta 2 that will most likely be an issue when the product goes to RTM. I notified Microsoft of the issue and they have pushed this back to VS 2008 SP1 because its so late in the development process. The issue is with adding a web service to a website. When adding a web service to a pre-existing website, a template for a web service is created. It will take VS 2008 to realize that the file has inline code. Then, when adding a snippet (right-click in the code window and choose Insert Snippet) that contains imports for a namespace, the namespaces are added at the top of the page like:

Using Animations with the PopupControlExtender

I was looking for a solution to provide a “fly-in” form when a user would click on a particular button. I found it with the PopupControlExtender. The documentation for Animations with controls is poor so with some testing, I finally got a solution working for me. I added a button and a panel on my page. I set the panel below the button and set the style to:
