the code sample below demonstrate how to open EA COM Object and open EA project file then get list of the project models

// connect to EA COM object     
EA.Repository _repository = new EA.RepositoryClass();
// Open EA project file
bool fileOpened = _repository.OpenFile(filePath);
if(fileOpened)
   Collection models = _repository.Models; // collection of models inside of opened project

Answer 3

To open a running instance use (C++ example)

CLSID clsid;
CLSIDFromProgID(L"EA.App", &clsid);
IUnknown *pUnk = NULL;
IDispatch *pDisp = NULL;
HRESULT hr = GetActiveObject(clsid, NULL, (IUnknown**)&pUnk);
if(SUCCEEDED(hr)) {
  hr = pUnk->QueryInterface(IID_IDispatch, (void **)&pDisp);
}
