I am actually working on porting an existing Delphi component to an ActiveX.
Almost everything is going fine, having solved most of the compatibility
issues b/w COM and Delphi.
But i am really stuck with this one. Please help me.

The explanation:
----------------
I am basically working on Delphi, converting a delphi component into an
ActiveX.
I am creating an ActiveX wrapper around an existing Delphi component.
All my interfaces call the corresponding methods of the wrapped Delphi
component wrapped inside the ActiveX wrapper.

My requirement is, I need to have a method that accepts another Activex
component.
I.e. If I have two ActiveX components dropped on the client form, I need to
pass an activeX
as a parameter to a method, another activeX that is dropped. Probably I can
pass the
corresponding interface.

Now in the server I want to access through the passed interface some data of
the
corresponding wrapped Delphi component. I am getting access violation if I
do this.
Can I not access from one activeX, data belonging to another ActiveX that is
dropped.
The data that I am trying to access actually belongs to the wrapped
component inside
the ActiveX server.

Example:

In Client: //OCX1 and OCX2 are the two instances of the same ActiveX
dropped
OCX1.SomeMethod(OCX2);

In Server: procedure SomeMethod(OCX)
begin
//FDelphiControl is the wrapped Delphi component in the
ActiveX server.
//It is a private member in the implementation class of
the main interface
//of the ActiveX.
ShowMessage(OCX.FDelphiControl.SomeTextProperty);
//I get "catastrophic failure" here.
end;

Please suggest. Please let me know with good links which might have probably
discussed these kind of problems.

Thanks in Advance
