Code to Register COM Object in Running Object Table

STDMETHODIMP CPPName::FunctionName(BSTR bsName)
{ 
    ConInitialize(NULL);
    CComPtr<IBindCtx> pbc;
    CComPtr<IRunningObjectTable> pROT;
    CComPtr<IMoniker> spMoniker;
    CComPtr<IUnknown> spUnk;
    CComPtr<IEnumMoniker> IMonikerEnum;
    DWORD dWCookie;

    CreateBindCtx(0,&pbc);
    pbc->GetRunningObjectTable(&pROT);
    CreateItemMoniker(NULL,bsName,&spMoniker);
    QueryInterface(IID_IUNKNOWN, (void**)&spUnk);
    pROT->Register(ROTFLAGS_REGISTRATIONKEEPSALIVE, spUnk, spMoniker, &dWCookie);
    CoUnInitialize();
}

Use Register COM Object in other COM Object

STDMETHODIMP CPPName::FunctionName(BSTR bsName)
{
    ConInitialize(NULL);
    CComPtr<IBindCtx> pbc;
    CComPtr<IRunningObjectTable> pROT;
    CComPtr<IMoniker> spMoniker;
    CComPtr<IUnknown> spUnk;
    CComPtr<IEnumMoniker> IMonikerEnum;
    DWORD dWCookie;

    CreateBindCtx(0,&pbc);
    pbc->GetRunningObjectTable(&pROT);
    
    <Loop For Moniker, Checking Name Provided>
       hr = pROT->GetObject(pMon, &pInterface);
       <IF Get Name of Moniker> == bsName>
          hr = pInterface->QueryInterface(IID_IAttach, (void **)pAttach);
       <End IF>
    <Loop End>
}

"pAttach" object having access to object that is Registered.
By this "pAttach" having access to methods of object.

Problem:

I am having One Exe with Object that is registed.
In another exe I am using another object giving name that is already registered.
Now my task is from first exe when i m clicking left button then second exe should get message.

Is there any way to access register object's event in another exe??
