VS 2008 Cancel A SQL Query?

Mar 20, 2009

I've run into a bit of an issue. Sometimes a user starts a search, but doesn't want to wait for the search to finish because they thought of some change they want to make or because the search is taking too long.

How would I cancel a Search? I understand that I would have to run the Search on a separate Thread. Would I just abort the Thread? Or do I need to send SQL Server something to let it know that it can cancel the query?

Cancel An ASP.NET MVC Action?

May 12, 2009

This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":

Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)

[Code]....

In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.

How To Cancel Thread

Jun 12, 2009

I am not familiar with threads, but the project I am working on has a bunch of them. There's a thread for the main form, then threads for activities like a calculation, converting files, etc, so that the user can kick off a calculation job and then kick of a conversion job that will run at the same time. Typically, calculations can run for hours and hours; conversions and other threads may only run a few minutes.If the calculation runs into a problem, how do I cancel that thread? It looks like the threads are controlled (driven?) by the main form, but I'm at a bit of a loss.....
