Calling EndXXX - Is it required and how?

[Nick Dodd via .NET 247]

Hi,

I have just implemented a reporting system for a web applicationI am responsible for where I work. It basically allows users toenter the report details, click a button and then fires off acall to an asynchronous web service that executes a storedprocedure on SQL Server as a background process.

Getting it to run is fine, but what happens if I don't call theEndXXX method once the web service (and stored procedure) havefinished. All the results are loaded into a table in thedatabase so I don't need any return values, but should I callthe EndXXX method to free up any resources or is this doneautomatically.

If I do need to call it, how should I do this. Once the reporthas been fired, the user is free to navigate around the systemto perform other tasks. This means (or so I believe) the AsyncInterface is lost and I don't want to store it in a Session. Sohow would I go about calling the EndXXX method with the correctinterface.

I am fairly new to .NET and Web Services, so hopefully I haveexplained and understood the above correctly.

Thanks for your help.

Nick.

You usually specify a callback in the Async object, and in that call back,
you call the EndXXX method.
