[C++] Leggere dei valori interi da un oggetto COM scritto in C#

[trancegate]

Da C++ istanzio la COM in questo modo:

int DBInitialize ()
{
IDbInterfacePtr ptrDB = NULL;
	HRESULT hr=NULL;

				try 
				{
					hr = ptrDB.CreateInstance (L"OSNETDBInterface.DBInterface");
					
						if (FAILED (hr)){
							_com_raise_error (hr);
							DEBUG_OPEN("%s","(DB Module) Initialization COM failed");
						}
						ptrDB->Init(configIDInstance);
					
					DEBUG_OPEN("%s","(DB Module) Initialization COM successfull");
                                    
					
				}
			catch (_com_error &e) {
				
					strMessage.Format ("(DBInitialize) Caught COM Error: " \
										"(HRESULT Code) %08lx - (Win32 code meaning) %s - (Description) %s - ",
										e.Error (),
										e.ErrorMessage (),
										e.Description ());
					DEBUG_OPEN ("%s", strMessage.GetBuffer (0));
				
				
			}
