The PPJ FrameworkLegacy Apps, Native on .NET
The PPJ Framework is the compatibility library that ported applications rely on to run on .NET. It supplies the libraries and plumbing code for features that are missing — or work very differently — in the standard .NET Framework, so your migrated application behaves exactly as it always has.
What the PPJ Framework Is
The PPJ Framework is the collection of libraries that ported applications need to support behavior that is unavailable, or too different, in standard .NET. It bridges the gap between generated .NET code and the runtime — a complete replacement and enhancement for Team Developer and SAL functionality, written entirely in C#.
It also redefines legacy "static" methods into modern object-oriented code, so developers manipulate UI controls, variables, and classes using standard .NET syntax — while the framework quietly preserves the semantics the original application depended on.
What the Library Provides
The framework is organized into functional areas that mirror what Team Developer offered — kept consistent across both the desktop and web implementations.
Compatibility Layer
Supplies the libraries and plumbing code that let ported applications execute features that are missing or drastically different in the .NET environment.
Modern Object-Oriented Approach
Redefines legacy static methods into modern object-oriented code, so UI controls, variables, and classes are manipulated using standard .NET syntax.
Reporting Support
Maps legacy reporting engines directly to modern tools — Crystal Reports, SQL Server Reporting Services, Stimulsoft, and Combit List & Label.
SQL Binding
Provides the SQL handling and data-binding behavior that SQLWindows / Team Developer applications expect, adapted onto standard .NET data access.
COM / ActiveX & DDE
Restores COM, ActiveX, and DDE interoperability so existing integrations keep working without being rewritten.
Visual ToolChest & QuickObjects
Implements the Visual ToolChest and QuickObjects libraries using native .NET controls and classes — with no proprietary controls.
Legacy Reports, Modern Engines
The framework maps legacy report definitions onto today's reporting engines, so existing reports render through a modern tool of your choice.

One Framework, Two Targets
The same functional areas and namespaces are kept consistent across both implementations, so the choice of target does not change how the application behaves.
Web — Wisej.NET
Targets full-stack web applications built on Wisej.NET, delivering the ported application as a modern, browser-based cloud app.
Desktop — WinForms
Targets native Windows desktop applications on WinForms, keeping the application on the desktop while running on .NET.
A Lightweight, Modular Architecture
The framework's architecture is deliberately very thin: most of the low-level work is left to .NET, while PPJ provides the plumbing code, adapts parameters, and checks for errors. It is a set of separate, strongly-named assemblies.
Applications reference only the assemblies they need. Unused modules — such as DDE or a particular reporting engine — are simply never deployed, keeping the footprint small.
