I want to have a series of COM objects in DLL's that all implement the same interface - but in different ways. I can create an interface and a coClass in the same project but I really want is to create a coClass and implement an existing interface which is defined in a 'parent' TLB. I know I can do this manually without a tyoe library but can I do this with the Type Library Editor? If I look at the implements page for a coClass it only lists a few interfaces, including the interfaces in the current type library. --------------------------------------------------------------------------- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz
