Hi!
I'm not completely sure what are you mean. Do you writing a C++ COM dll which uses a third party COM library and you need to import type definition from that library? In that case you can use a native VC++ 6.0 compiler support for COM objects by #import statement:

#import filename no_namespace

where filename is name of file with type library information (.DLL, .EXE, .OCX, .TLB or .ODL)

>I have a COM dll which exports a single TYPE. The type is a structure of data types. I need to create a dll that impliments that type because I have a third party control which accepts parameters but only as/in that type. How can I import that type.
