tlb COM file generation for C++ project

See more:

COM

I have a simple C++ project. It has 1 COM interface with 2 very simple function. Everything compiles fine, but a TLB file is not being generated?? Is there any setting I need to set in Visual Studio? I tried setting the /TLBOUT linker flag but that doesn't do anything.
I tried setting the option for registering the dll, but I get an error that registration failed.
Any ideas ?

class CTestObj : public ITest
{
public:
    void __stdcall Method1 (CString input) {cout<<"Input String: "<<input<<endl;}
    void __stdcall Method2 (int data){cout<<"Input Number: "<<data<<endl;}
};
class  __declspec(uuid("{206C2246-1047-42a2-96EE-0F9FBE776823}"))
                  CTestObj;

Dependency walker is not showing any functions in the resulting DLL. Should I use dll export? Something along the lines of:

Dependency Walker is showing no functions. Do I have to use dll export ??

Should I do something like this ?
<pre lang="c++">__declspec(dllexport) STDMETHOD(Method1) (CString input) = 0;</pre>
