OLE Automation compatibility interface for IEnvelope.
Description
The IEnvelopeGen methods are designed to comply with any programming languages supported in ARCObjects (ex: VB 6.0, C++, Java, VB.NET, C#...). For example, writing code using this interface in VB 6.0 may result in less rework in a migration to VB.NET.
