Load the object from dll

[DmT021]

Hello all
There is a dll which I need to use.
I have an interface looks like this:
@[ object, uuid("00000000-0000-0000-0000-000000000000") ]
__interface Interface
{
public:
virtual bool Init(void) = 0;
virtual bool Destroy(void) = 0;
virtual bool Test(void) = 0;
};
@
There is a function in the dll, which gives a pointer to object of class with implements of that interface.

I can load the dll using QLibrary, and I can resolve this function, and call it. But how to declare the interface in the right way using -QT- Qt? And how to call the methods of given object?

solve:
@static const GUID IID_object = { 0x00000000, 0x0000, 0x0000, { 0x00, 0x00, 0x0, 0x00, 0x00, 0x00, 0x0, 0x00 } };
class Interface : IUnknown
{
public:
virtual bool Init(void) = 0;
virtual bool Destroy(void) = 0;
virtual bool Test(void) = 0;
};@

PS: guid also could be resolved via QUuid

Looks like you are using COM, right?
Why don't you use COM methods then? like CoCreateInstance etc?
