Remarks

The code example that follows illustrates how this method is used to create a new interface.

IXpsOMPackage    *newInterface;

// Note the implicit requirement that CoInitializeEx 
//  has previously been called from this thread.

hr = CoCreateInstance(
      __uuidof(XpsOMObjectFactory),
      NULL, 
      CLSCTX_INPROC_SERVER,
      __uuidof(IXpsOMObjectFactory),
      reinterpret_cast<LPVOID*>(&xpsFactory)
      );

if (SUCCEEDED(hr))
{
    hr = xpsFactory->CreatePackage (&newInterface);
    if (SUCCEEDED(hr))
    {
        // use newInterface

        newInterface->Release();
    }

    xpsFactory->Release();
}
else
{
    // evaluate HRESULT error returned in hr
}
