It's a new unit (first included with fpc 2.4.4) and therefore not yet

For the interested:
I got news from the editor (chairman of the Dutch Pascal User Group) that the Lazarus book
"Lazarus Complete Guide" is now available for sale.

I created a small automation object with following IDL (part of it):
interface ItestAX: IDispatch
{
[
propget,
id(0x0001)
]
HRESULT _stdcall Devices([out, retval] IDevices ** Value );
};
interface IIDevices: IDispatch

Difficult to debug without having the dll. If item := items.item[1]; raises
a "wrong number of parameters then the items.item member is found. I don't

Ah, thanks Michael that did the trick. I knew I had to be doing
something wrong.

Hi Ludo,
I really cannot get the items to work. I simplyfied the source code to
the minimum in order to test the items stuff.

items := obj.Transducers; // OK

I tried ptcgraph by a mere change of names, and it works, more or less.
However, the graph unit still appears in the doc, whereas I cant't find
no doc for pctgraph.
Some help?
