Overview

Herbert-ABS offers leading edge loading and salvage analysis software packages as well as software design tools to the maritime and offshore industries. It owns, markets and supports the existing suite of Herbert software products including its shipboard loading software (CargoMax), salvage response software (HECSALV), and load management software for offshore structures (LMP). Its latest software solutions include an enhanced containership stowage module, performance monitoring and optimization tools, and a load management, condition monitoring, and emergency response package for offshore vessels and structures. Great Migrations worked with HerbertABS Herbert-ABS to accelerate upgrading their VB6 to .NET. Great Migrations used gmStudio to generate a C# system containing 22 application projects generated from the VB6 codes and also containing a COM stub framework generated from the COM dependencies. All projects were cross-referential and organized into a VS2015 project for subsequent refactoring, verification and optimization by the HerbertABS Herbert-ABS development team.  The development of this "Phase 1" upgrade solution took about 10 weeks.

...

All COM dependencies were 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 available as source code.  This This framework was subsequently upgraded to functional .NET components by the in-house development team as part of their effort to verify and optimize the generated .NET code. Some of the COM components included in the stub framework are listed below.
