I want to generate alert using asp.net. Scenario is; In one stock website I found stock x is at $50. I want to get informed when the stock reaches $60.  System should send me an e-mail when it reaches to $60. I don't want a program running in a background (in schedular of windows) to do this task.
Thanks

This can be acheived by taking advantage of the threading namespace available in .NEt.   Basically, the idea is that you spawn off a thread which has access to the parent object.   It keeps track of a property in the parent object, in this case, stock price.    In a loop, if the stock price is less than 60, it just sleeps and tries again.  But when it is above 60, you can use the parent object to invoke a callback method, which will handle your alert.

Threading is too detailed to get into on here, but here is a place to start reading.

Ashish,

Your criteria about background/scheduling is not clear.  There are two ways your program could run:

1. An EXE that constantly monitors the stock and sends email when some condition is reached, or
2. An EXE that checks the stock once, and that EXE is scheduled to run on a regular interval.

I'm not sure which one you're asking about.  In either case, this sort of application is probably more at home in the C# category as it is not the sort of thing you would code as an ASP.NET page.  Well: you could code it as an ASP.NET page, and keep on hitting "Refresh."

Good point barry,
I kind of lost track of the ASP.Net part.  Threading is a solution that will work better with desktop appliations.   HOwever ASP.NET can be C#, or VB.NEt, or any other supported language.
