Nested Groups in Regex

- by cryptic-star

I'm constructing a regex that is looking for dates. I would like to return the date found and the sentence it was found in. In the code below, the strings on either side of date_string should check for the conditions of a sentence.

How can I make a security token automatically expire in a passive STS setup?

- by Rising Star

I have a passive STS set up for a new application I'm working on. I've noticed that when a user's session expires, the user is still authenticated.

I have several servers to test new code on. I primarily push out asp.NET web applications. Last week, I had an issue where I installed a newly developed web application on three servers.

Page inheritance in mixed asp.net Forms and MVC application

I'm working on a web application. One of my co-workers has written some asp.net forms pages. The page classes all inherit from BasePageClass, which of course inherits from the Page class. I wish to add some MVC controllers that I've been told need to use the same logic implemented in the BasePageClass. Ordinarily, I would want to…

What is a good practice for handling SQL connections within a WCF call?

- by Rising Star

Suppose I want to create a (stateless) WCF service with three methods exposed on an endpoint: performSqlOperationA(), performSqlOperationB(), and performSqlOperationC().

Claims-based Authentication: Are strings the essence of claims?

- by Rising Star

I've been programming with claims-based authentication for some time now with Windows Identity Foundation. It appears to me that in Windows Identity Foundation, once a user is logged in, the claims are basically strings of information that describe the user. With the old role-based authentication, I could say that a user…

How does IIS persist a user's identity from page to page?

We use things like cookies, session-variables, and query strings to maintain state from page to page. When you log in to an ASP.net web application using…

Here's a simple question I've been stuck on for a while.

Is there a tool that will show diagrams of my SQL database in real-time?

I've created some diagrams of SQL tables using the "Reverse Engineer" feature of Microsoft Office Visio. I like being able to visualize my relational databases in this manner. However, what I get is just a static document that I can print, e-mail to colleagues, and click widgets on. Earlier this year, I saw at…
