Getting Properties of Objects

This section shows example code to get properties of objects. The example code uses:

CMetaObject::GetPropertyValue

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

// GetAutoProp function

//

// Read Auto Object and Get Auto Properties.

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

HRESULT GetAutoProp()

	double		Height;

	int			Weight;

	String		VehicleType;

	String		Review;

	HRESULT		result = S_OK;

	// Read by ClassGUID and Name
