accessing properties through com

[sanka69]

Hi all,
I have a third party ActiveX control which as a property ACStyle. I was under the impression that I could refence the properties of ACStyle like this:

: ac is the name given to the control on the form.

var
acColor : TColor;
begin
ACColor := ac.Style.BackColor;
end;

However this causes an access violation. Can someone tell me what I need to do to access this property?

Thanks,
Richard

Shortly after posting, I realised that the ac.Style was a pointer, however taking that into account I still get GPFs when trying to read or write back to individual elements of the record.

Can anyone advise me please?

Thank you,
Richard

If Style is a pointer, you need to dereference it:

ACColor := ac.Style^.BackColor;
