What the Native property value in {} means?

[JeL]

Hi, 

When spying objects I can see that some Native properties have values mentioned in {} . Can you advise what does it mean and whether these kind of values can be used to define an object?

Thank you

Solution to retrieve object was found by adding .ToString after desired native property (Header)
nativePropertyVal = tabCollection(i).Object.Header.ToString() 'Use the native property in place
