Re: CoCreateInstance inside a COM dll?

Am sorry for the total mess up with the code. While typing i missed
some important parts of the code, its not that those pieces of code
are not in the original.

Here i go with the proper code again,

STDMETHOD GetMyInterface(IMyInterface** pMyInterface)
{
-------------------------
HRESULT hr = QueryInterface(__uuidof(IMyInterface), (void **)
pMyInterface);
------------------------
}

And also the Client code like this,

GetInterface()
{
IMyInterface** pInterface;
HRESULT hr = m_pFirstInterface->GetMyInterface(pInterface);
}

Another thing is the interfaces are inherited here,

Like,

interface IFirstInterface : IUnknown{};

interface ISecondInterface : IFirstInterface {};

interface IMyInterface : ISecondInterface {};

interface ITopInterface : IUnknown {};

interface IClientInterface : ITopInterface {};

This is the inheritance structure of interfaces in COM IDL file.

I am trying to QueryInterface the IMyInterface from inside
IClientInterface.

Hope this helps in getting a better understanding of what am trying
to do.

So any guesses about the error am getting?
It's an Unhandled Exception.
