Rolls-Royce Nuclear Engineering Services -- AutoTour (VB6)
- Mark Juras
Overview
Rolls-Royce Nuclear Engineering Services helps Naval and commercial utility customers to maximise plant operation and safely extend plant lifetimes. Their AutoTour and RoundsMaker applications facilitate conducting and tracking power plant inspections.
Great Migrations worked with Rolls-Royce to implement an initial upgrade solution producing an integrated build-complete VB.NET system. Great Migrations delivered the solution along with a gmStudio license and provided training and support so that the Rolls-Royce team could continue development and optimization of the upgrade solution in-house.

COM Upgrades
All COM dependencies were initially satisfied by a COM stub framework generated automatically from actual COM usage found in the source codebase. The generated stub framework contained assemblies generated for third-party COM components as well as in-house components not provided as source. This framework was subsequently upgraded to functional .NET components by the upgrade team as part of their effort to verify and optimize the generated .NET application code. Â Some of the COM components included in the stub framework are listed below.
| Microsoft Access 14.0 Object Library Microsoft ActiveX Data Objects 6.1 Library Microsoft ADO Ext. 6.0 for DDL and Security Calendar Microsoft Windows Common Controls 5.0 (SP2) Crystal  | Microsoft Excel 14.0 Object Library Graphics Server Extended Graph Microsoft Common Dialog Control 6.0 (SP6) Microsoft XML, v3.0 Microsoft Scripting Runtime Microsoft Word 14.0 Object Library |
Upgrade Features
The core features of the translation tool were enhanced to produce more build-complete VB.NET code.
