Scheduler Pro Ocx (specifically packaged as ScPro.ocx) is a legacy ActiveX component designed by Gaia Consulting for software developers to build fully interactive Gantt charts and project planning management engines within desktop applications.
The component serves as a specialized user interface (UI) and processing engine, allowing legacy programming languages to implement complex visual project management features with minimal code. 💻 Supported Development Environments
As an ActiveX (.ocx) control, it is deeply tied to the Windows ecosystem. It was historically tested and integrated into rapid application development (RAD) environments, including: Microsoft Visual Basic 6 (VB6) Microsoft Access (VBA) Microsoft Visual Studio .NET (VB.NET, C#) Other older desktop systems that support ActiveX containers ⚙️ Core Technical Features
Unlike standard Gantt charts which are purely visual, Scheduler Pro includes an automated calculations backend. Its prominent features include:
Forward Scheduling Algorithm: An integrated algorithmic system that automatically calculates timeline block placements for workflows.
PERT Logical Links: Handles predecessors and successors for blocks, visually connecting them via arrow lines inside the Gantt view while maintaining date logic when shifting timelines.
Resource Balancing: Contains a load-balancing algorithm capable of automatically distributing tasks across similar resources within a grouped category.
Combined Capacities: Allows developers to manage finite-capacity resources (like a physical factory assembly line) and infinite-capacity resources (like an external supplier) within the same project space.
Overlap Prevention: Includes an engine that accounts for non-working hours and prevents blocks from mistakenly overlapping on a timeline. 🛠️ Programming Anatomy
