Our office is about to finally spend some more money updating the in-house reference library and I suggested that we pick up some more books that focus on Object Oriented Programming/Design from a .NET perspective (which is what we focus in, primarily VB and ASP.NET). After doing a quick look through our current shelf we seem to only ha...
Hi folks, I have an ASP.NET application that starts a long running operation during the Event Handler phase in the ASP.NET Page life cycle. This occurs when the end user pushes a button a bunch of queries are made to a database, a bunch of maps are generated, and then a movie is made from jpeg images of the maps. This process can take o...
Does anyone know how to detect in a OnBeforeUnload event that the server side code sent a Response.Redirect? I want to prompt a user to keep them from moving away from a page before it's time, but when the server redirects I it shouldn't prompt the user. I'm working with legacy code that extensively uses Response.Redirect and I'm not i...
Hi, I have a ShareThis (http://www.sharethis.com) link in the footer of my Masterpage. The code they provide generates the link via Javascript.

One of the requirements proposed for an ASP.NET application is that we have Session state disabled globally. (This is not negotiable.) Another requirement is that we have some means for user authentication. I'm thinking of using ASP.NET's membership provider model. Is it possible to have user authentication without Session State? The ...

Has anyone used Component Arts Web.UI controls? They look like a great set of tools but is it worth the $998 they charge? ...
The obvious issue here is that on refresh a button event is recalled and duplicate posts are created in the database. I have read other questions on this site about the very same issue. Apparently the answer is for every post create a GUID and check to make sure the GUID is unique? I am not really sure how to implement this. Does that...
At my place of employment, they have a system that uses VBScript to build fields when loading up a record. The advantage is that it works on various database backends the same way and also makes sure that the record is loaded the same every time. It also allows customers access to make some minor changes to the way the system works in ...

I am using sessionstate stored in stateserver in asp.net. I have a link on header that displays users login id. Problem: When session expires in stateserver my application still displays loginid and it throws an error when hits code that depends on value stored in session.

I'd like to HtmlEncode one of the properties of the contained objects before binding to the control, but I want to do it without altering the data because I do a DataContext.SubmitChanges() later on. How can this be done? Code that won't work: var ds = (from s in dc.Search...
