Step-by-Step Example

 * 1) Start a new transaction in Visual Basic.

 * 4) Create at least one property and attach it to the new interface.
 * 5) Commit the transaction to save the new TIM.
 * 6) Create an object instance based on the newly-defined class.
 * 7) Try to access the property off the default interface using the following format: "Value = Object.Property."

EXPECTED:

No error.

RESULTS:

Error number: 438
