Async Search and Query on contentDirectory

[ChriD]

Hi,

Is there any chance, if i use async search or browse on contentDirectory,
to pass some information to the "sink" Method? I get some IntPtr that is used to get the correct data, but i do not know from which context it was called.

eg.

contentDirectory.Browse(..., BrowseSink);
contentDirectory.Browse(..., BrowseSink);

protected void BrowseSink(IntPtr _ptr)
{
// do i come from first Browse or second browse?
}

best regards
Chris

You can use a lambda to add some call-specific data:

contentDirectory.Browse(..., (asyncHandle) => BrowseSink(asyncHandle, 1));
contentDirectory.Browse(..., (asyncHandle) => BrowseSink(asyncHandle, 2));

private void BrowseSink(IntPtr aAsyncHandle, int aOther)
{
}

I'm sure you can pass something more interesting that a counter as an extra argument. aOther above is just a simple example of the sort of thing you could do.

Thank you very much!

Work's like a charm!
