Getting Collections of Object Keys

This section shows example code to get collections of object keys. The example code uses:

CMetaObject::GetDestCollectionKeys

CMetaObject::GetOrigCollectionKeys

The example code also shows how to iterate through the returned vector of object keys.

////////////////////////////////////////////////////////////////////

// GetDestCollKeys function

// Reads and print a collection of keys. 

//

// Example of using the CMetaObject::GetDestCollectionKeys function

////////////////////////////////////////////////////////////////////

HRESULT GetDestCollKeys()

{

	MetaObjectKeyVector objectKeys;

	HRESULT			result = S_OK; 

	CMetaObject		obj;     

	obj.SetClassGUID(CLSGUID_AutoDiv);

	obj.SetObjectName(_T("AmericanAutos"));

	if (SUCCEEDED(result = obj.ReadObject()))

	{

		// Get collection of object keys (name and objectid)

		// of all Autos of AmericanAutos

		result = obj.GetDestCollectionKeys(objectKeys, 

			RELGUID_DivMakesAutos);

		if (SUCCEEDED(result))

		{

			cout << endl;

			cout << ">>> Collection of object keys (name and objectid) ";

			cout << endl;

			cout << ">>> of all Autos of AmericanAutos" << endl;

			PrintKeyList(objectKeys);

			CLEARVECTOR(objectKeys);

		}

	}

	return(result);

}

/////////////////////////////////////////////////////////////////////

// GetOrigCollKeys function

// Reads and print a collection of keys. 

//

// Example of using the CMetaObject::GetOrigCollectionKeys function

/////////////////////////////////////////////////////////////////////

HRESULT GetOrigCollKeys()

{

	MetaObjectKeyVector objectKeys;

	HRESULT			result = S_OK; 

	CMetaObject		obj;     

	obj.SetClassGUID(CLSGUID_Auto);

	obj.SetObjectName(_T("Yearling"));

	if (SUCCEEDED(result = obj.ReadObject()))

	{

		// Get collection of all Auto Divisions of Yearling

		result = obj.GetOrigCollectionKeys(objectKeys, 

			RELGUID_DivMakesAutos);

		if (SUCCEEDED(result))

		{

			cout << endl;

			cout << ">>> Collection of all Auto Divisions of  Yearling" << endl;

			PrintKeyList(objectKeys);

			CLEARVECTOR(objectKeys);

		}

	}

	return (result);
