This article describes how gmStudio may be used to upgrade Third-Party Controls and COM APIs.
...
Overview
gmStudio has an Open Type System that allows us to recognize, interpret, store, and express information about how VB6/ASP codes use COM APIs. This includes both third-party COM APIs and controls and COM APIs and controls defined by your VB6 codes.
Our type system allows users to specify rules that adjust how the type system works includes
- defining custom types,
- enhancing the legacy COM API's object model, and
- mapping COM API to various .NET replacements.
These rules may be
- declarative using an XML notation,
- implemented using our scripting language, and
- implemented using our C# API.
gmStudio's open, extensible capability for COM API replacement is arguably the most powerful feature of our platform.
