Reading and Displaying Objects

This section shows example code to read and display objects. The example code uses:

MetaObject::ReadObject

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

// ReadByClsGUIDName function

//

// Set ClassGUID and Name to Read object.

	PerformReadObject(obj);
