With ASP.NETs DataSource controls you can parameterize your query and have those parameters automatically fetched from one of a few standard sources. Those include getting a parameter value from the querystring, a form parameter, a control or from a users session variables, profile or cookies.
These parameter types enables us to build a lot of functionality without leaving ASP.NET markup. Still, they don’t cover every imaginable scenario. So when someone asked how to get the username as a parameter in this question on Stackoverflow, it inspired me to write this article. read more»
In this previous posts about Windows Azure Table Storage, I relied on the StorageClient project in the Azure SDK samples. This feels a bit strange, and raises the question: Am I expected to include references to sample projects and be using Microsoft.Samples.whatever namespaces in my future projects?
This raises a couple of questions about license, copyright, support and more. Instead of digging into those questions, I came up with some alternate questions:
- What does this sample project give us?
- How does it work?
- Can we do these things ourselves?
A lot of the searching was done in the sample code, since most of the other articles about accessing Windows Azure Table Storage depend on the same sample files. I was disappointed to see that even the Windows Azure SDK help file shows some partial code calling into the sample project. Little help there… read more»
When searching for articles/blogs/samples about using Azure Table Storage from .NET, it seems most of them (if not all) depend on the StorageClient sample in the Azure SDK. I read about authentication with SharedKey or SharedKeyLite, and I always found the magic of these authentication schemes were wrapped up into several layers of abstractions in this SDK sample.
Hoping that I could get at my data without it (the sample), I needed to research how to authenticate against Azure Table Storage. So how does it all work? read more»
I found several great articles showing how to work with Windows Azure Table Storage:
All these, however, assume that the table storage will be used from an Azure web or worker role. I wanted to see if the Windows Azure Table Store could be used with applications running elsewhere, like on your computer. I’m creating a console application here, but the code can be easily adapted to a WPF, Windows Forms or even an ASP.NET application too. read more»
RecentIy I needed to find a specific TreeNode in a TreeView control. I expected that would be easy with LINQ, but quickly realized that there is no method in the .NET framework that will let me traverse all nodes of a hierarchy. I decided to create one myself. read more»
In this previous article articles about parsing files, I took a very simplistic approach to reading a delimited file. I used string.Split, which doesn’t handle the use of quotes and usage of the delimiter character inside quotes.
Well, it turns out theres more to reading a delimited file than splitting at the delimiter… read more»
In a previous article, I described how to use LINQ when parsing a textfile.
Following that train of thoughts further, I found a more elegant way of splitting the lines from the file into columns. Creating extension methods on top of IEnumerable<string> seems like a good idea! Something that could be used like this for a comma-separated file:
from columns in reader.AsEnumerable().AsDelimited(delimiter)

Reading and parsing files is really no difficult task with the .NET framework. The System.IO namespace has several good classes to aid that task. read more»
