Trouble using .NET dll in CPP Builder

daktmacfandaktmacfan Posts: 1Member
I have created a COM callable DLL in C# .NET 2.0 and created a TLB from the assembly using the .NET regasm tool.

In Borland C++ Builder 4.0 I go to Project->Import Type Library-> and find my DLL's type library there and click "Ok" to import it.

BCB creates an HardwareCheck_TLB.cpp & HardwareCheck_TLB.h file.In a cpp file of the project I want to use the DLL I put: #include "HardwareCheck_TLB.h"
at the top.

Then in code if I try to declare an object of that type in code: IHardwareCheck hc = new IHardwareCheck();
I get the following compiler error:

[C++ Error] Unit1.cpp(22): E2352 Cannot create instance of abstract class 'IHardwareCheck'.
[C++ Error] Unit1.cpp(22): E2353 Class 'IHardwareCheck' is abstract because of '__stdcall IHardwareCheck::IsExpress(wchar_t * *,TOLEBOOL *) = 0'.

Anybody have any ideas how to get rid of this error?

Thanks!
