Re: How to get the info from a handle?

As Larry said, GetDataBrowserItems() expects an allocated handle (it will resize it to match the number of items returned).

Handle h = ::NewHandle(0);
::GetDataBrowserItems(browser, kDataBrowserNoItem, false, kDataBrowserItemIsSelected, &h);

If I remember correctly, OS X doesn't like handle sizes set to zero. I am not 100% sure about this

I can't say I've ever had issues with 0 sized handles on OS X. However, there are differences in how 0 sized pointers may be dealt with depending on OS (at least as I'm remembering in the past) as some libraries return NULL while others return a valid pointer.

Failure is not an option. It is a privilege reserved for those who try.
