Web Forms :: Display Content On Page Based On Column In Database?
Jan 7, 2011i am using MSSQL Server 2005 with VB in my codebehind. I have an application that I have written as a time tracking system that uses SQL Membership provider to secure the site with forms authentication. I want to add additional functionality to the site. My company has a intranet SharePoint site. I want to add something on the front page of the SharePoint site that will allow the users to clock-in/out without having to login to the application. I have a users table that is not part of the SQL Membership Provider that holds detailed information about the employees. There is a column in that table that identifies users as being able to use the clock-in system. I want to be able to display a clock-in/out button on the paged based on that column. Not all users have the ability to clock-in as their time does not need to be tracked.

Apr 2, 2010I was wondering which of these two is better from the aspect of performance.
I was thinking that possibly Class files stored in App_Code works faster because they are sort of pre-compiled but i am not 100% sure.
Specifically i am overriding onInit event on each page using some functions that i am not certain where to place.
Not that i complaint on the speed but i want to be sure that i am doing the right thing.
Configuration :: .Net Website Performance Of 2 Sites - Rectify The DB Performance While Insertion?
Sep 20, 2010I have developed a website in asp.net framework 2 . This website is being hosted in two different servers without any change in code. My issue is about the performance of these 2 sites. One website is taking much time for inserting datas to the DB (SQL server 2005). 2 websites are having different DB server.
I think the issue is for the DB server. How can we rectify the DB performance while insertion and Is there any other cause for this permance issue?
C# - What's The Most Important Effect On Performance In A Database - Backed Web Application
Feb 11, 2010I was recently asked to speed up a C#/ASP.NET/SQL Server business app website. Since I just started, I don't know too much about the internals. So where do I start? Sight unseen, what is the single most important thing affecting performance on a system like this? Database tuning? Hardware? Individual page optimization? What is the first thing you'd look at? EDIT: After I actually do the work, I'll come back and post the answer. ;)
EDIT again: "Profile" is currently the most-voted answer, and I agree that that is clearly what one should do. But I was looking for guesses/experience as to what the profiling results would show, so I don't think that answer counts...
