Create Asynchronous Service Provider

[Shilpa13]

Hi All Experts!

We are scanning the directory via active object and wanna display status of it on screen.

At the same time, application should respond to other UI events.

We should be able to cancel or pause the scanning process.

The asynchronous service provider can be a solution.

In SDK, its given how to use asynchronous service provider with active object.

But its not clear, how to create an asynchronous service provider.

I created low priority active object.

I need some clue to cancel or pause the ongoing operation in active object.

What may be the best possible approach for this..?

Experts plz guide.

Thanks.

Hi Shilpa,

I assume that your active object runs fine(scanning directories), just create an abstract class MReportSomething

eg.
class MReportSomething
{
virtual void CurrentStatusL(const TDesC& aResponse) = 0;
};

this class should be one the base classes of the view where you want to show the status.
Implement CurrentStatusL in the view class.

In your active objects RunL call CurrentStatusL on the MReportSomething observer e.g. iObserver.CurrentStatusL(aResp);
