[DUG] Importing .net dll to Delphi 6 loses information

[sinu sudhakaran]

Hi All,

I have a .net dll which I could import to Delphi 6. But it loses some information.
I have a demo application in VB.net to use this dll which shows 2 interfaces called
IRedeemTransactionItemBundle and ITransactionItemBundle. In visual studio 2008, I could see , ITransactionItemBundle 
Is the base type of IRedeemTransactionItemBundle. So when I decare a variable of type IRedeemTransactionItemBundle,
I could access all properties of both interfaces. But when I import the dll to Delphi 6, I could see
both  IRedeemTransactionItemBundle and ITransactionItemBundle declaration part. But there is no information shows
ITransactionItemBundle is the base type of IRedeemTransactionItemBundle. Also when I declare a variable of type 
IRedeemTransactionItemBundle in Delphi, I am not able to access properties of ITransactionItemBundle [the base type].

When I tried to register tpe library in tlb editor by setting the base type of IRedeemTransactionItemBundle to 
ITransactionItemBundle, I am getting the error “Parent Interface already has a member with id:1610743808”.
I have attached the screenshot. I could see properties of both interfaces have same ID in the tlb editor.

I tried to import the same dll using Delphi 7 also. But no help. 
Is that a problem with Delphi ? Have any of you experienced such a problem in importing kindly give me some thoughts.

Any help is appreciated.

Thank you,

Kind Regards
Sinu
