Dynamic SQL vs Stored Procedures
I bet all application development team had a debate on whether to use Stored Procedures or Dynamic SQL statements during their development. I read Bil Simser's blog on this and also Rob's blog and Frans Bouma's blog. What a lengthy feedback/comments and it defintely took a while for me to read everything but it is worth reading.

Other side of the table
I never interviewed anybody for a technical position and currently as one of my team member left our team, I was assigned to hire a asp.net developer position for our team. It is quite a experience as you need to filter the resume based on our requirement. I interviewed three guys so far and still did not find a good fit. Sometimes, I used to think whether I am so picky. But my questions are simple and all I need is a direct answer. This process made me think like how I would act if I am in other side of the table! Today I got to interview one person who played lots of managerial role in various project and only know the basic concepts of asp.net but this position requires serious asp.net skill and so I was not comfortable in asking some of the asp.net specific questions to him (when I know that he is not going to answer)

nigritude ultramarine
Wondering what it is? SEO Challenge held a contest for webmasters and site owners to come up with any search optimization technique to get the top spot on Google for a very odd term and Brandon Suit,owner of an online forum won the first place in the first round. It was sponsored by Darkblue and Searchguild.com. As it was rightly put it was a competition to demonstrate how strong a particular search/ranking technique are. Brandon Suit used backlinks - a technique in which the required words on other people's sites are hyperlinked back to his site. -

Multistep webform submission
Here is my requirement.
I need to collect lots of data from the user for our intranet application and store them in DB only if they provide all the required information. I am planning to use wizard kind of UI where the user has to navigate through each step and enter all the required information and Submit will happen in the last step. I am planning to use Usercontrols in panels in one aspx page for each step to collect inputs.
Now the question is how do you persist previous step(usercontrols) data til your reach final step for submission.
1) Session is one option if the size of data is small but in this case, it can be huge
2) Viewstate is another option but again I am doubtful whether it will persist the data when it is not posted back - that is I will show only one user control at any point of time and hide all the other user controls and so other controls will not be posted back. Otherwise I need to keep track of all the "value entered" usercontrols and keep posting back each one whenever I move to another step!!
Any other options?
Thanks

Exception handling in WinForms
My current project involves Windows Forms and all my previous experience involves WebForms. One thing I am wondering on Windows Forms is, why don't we have very broad error handling options in Windows Forms as WebForms. For example, we can trap error in ASP.NET in hierarchical way.

Link building
Recently happened to read this “10 steps to getting links to your site” from Microsoft site. It is an interesting article which talks about “Link building” and “link popularity” which is basically Google's Page Ranking mechanism.

Usage of Dataview
I have a datatable which has 10 different columns. I like to have 3 different dataviews with different set of columns for each dataview. Initially I thought Dataview can be considered as “Database View” as we Dataset is considered as in-memory Database. But I was wrong.

Need a template for FlexGrid
I recently joined new client where my work will be more of Windows Form programming. They are using ComponentOne's flexgrid with lots of customization and it looks great. When I started my new screen, I wanted to use same look and feel. Basically I needed a template for flexgrid with all the styles already set. But I was not able to create one as it puts all the style attributes inside the .vb file. I wish we can create a customized one flexgrid control and anybody who wants use can just drag and drop and then add their columns as per their need!!

Managing .NET development NAnt
When I was working with my last client, we developed our intranet site based on DotNetNuke framework and we needed a good building mechanism to make daily build. We tried our best with MS SourceSafe but did not work the way we wanted. Recently read this article by Justin Gehtland from TSS.NET and found very useful. Did anybody tried NAnt in real time multi developer team environment? But we also will have MSBuild from Microsoft in the future.
