Source Stack · Visual Basic 6
Visual Basic 6 has been unsupported since 2008 — yet mission-critical VB6 applications still run across enterprises worldwide. Every Windows update is a compatibility gamble. The developers who built these systems have long since moved on. Our AI factory parses your VB6 forms, modules, and COM components and converts them into a modern stack your team can maintain. Phased delivery. Full IP ownership. 3–5× faster than a manual rewrite.
Deep VB6 parsing in the factory. Proven Forms-to-modern-stack conversion pipeline.
The VB6 time bomb
VB6 applications run on a compatibility shim inside modern Windows — one update can break them silently. There are no security patches, no bug fixes, and no path forward. The developers are gone. The documentation is gone. The institutional knowledge lives in code that nobody dares touch.
VB6 codebases are tightly coupled — forms reference modules, modules reference COM objects, COM objects reference everything. Manual rewrites take 2–4 years and routinely lose the subtle business logic embedded in event handlers, default property behaviors, and implicit type conversions that VB6 is infamous for.
Inside the VB6 factory
Our AI ingests your VB6 project — forms, modules, class modules, user controls, COM references, and ActiveX components. It maps every event handler, property, data binding, and external dependency. Every artifact is logged and inspectable.
The AI emits idiomatic code in your chosen target stack — .NET (WinForms, WPF, Blazor, or ASP.NET), React + API, Node.js, or Java/Spring. VB6-specific patterns (Variant types, default properties, COM interop) are translated into modern equivalents. Senior architects review every structural decision.
Before any cutover, the AI synthesizes behavioral tests comparing new system output against the live VB6 application. Form by form, function by function. You migrate on a passing diff.
Three engagement stages
Start with a fixed-price diagnostic. If the conversion quality doesn't meet your bar, you owe nothing beyond the diagnostic fee.
Fixed price · 3–4 week turnaround · fee credited to full migration
Provide a representative VB6 project. We convert it and deliver with audit + dependency map.
Fixed price · scoped per module · phased delivery
SLA-backed AI conversion of your entire VB6 estate into your chosen target stack. Delivered in months, not years. Phased releases with parallel running — legacy and new system operate side by side until cutover is validated.
6–12 month retainer
Architectural support to onboard your team into the new codebase, CI/CD pipelines, and delivery cadence. We stay until your team owns it fully — no handover cliff.
What you walk away with
Next step
Start with the Proof of Architecture Diagnostic. Fixed price, 3–4 weeks, and the fee is credited against the full migration if you proceed. We'll convert a representative VB6 project to your chosen target so you can judge the output before committing.
