Auto-Analyzed

Visual Basic 6 Analysis

VB6 files are plain text — .vbp, .bas, .cls, and .frm — which means our analyzer can scan them fully automatically. And with VB6 carrying the highest modernization urgency of any technology we encounter, you need to know exactly what you're dealing with.

What the Analyzer Detects

  • .vbp project files — project structure, component references, version
  • .frm Windows Forms — form count, control types (CommandButton, TextBox, DataGrid, etc.)
  • .bas Standard Modules — procedure and function count, LOC
  • .cls Class Modules — class count, interface implementations
  • .ctl UserControl files
  • COM/ActiveX references — every registered DLL and OCX dependency
  • ADO/DAO/RDO database connectivity patterns
  • Crystal Reports embedding detection
  • Third-party OCX controls: MSFlexGrid, Sheridan, VideoSoft, True DBGrid, etc.
  • Target compatibility: Windows XP/Vista/7/10/11 runtime issues flagged

Your VB6 Modernization Options

Desktop technologies like VB6 offer flexibility in how far you modernize. We can upgrade the runtime and libraries while keeping the desktop form factor — or take the opportunity to go fully web-based. We help you choose the right path based on your users, your budget, and your business goals.

Upgrade to C# / VB.NET on .NET 8+

Keep the Windows Forms UI paradigm your users know. Migrate to C# or VB.NET on .NET 8, replace COM dependencies with modern NuGet packages, and get a supportable, maintainable desktop app. Lowest disruption — highest speed to market.

Good for: Internal tools, back-office apps, small user bases

Migrate to ASP.NET Core / Blazor

Transform your VB6 desktop app into a modern browser-based application. No client installation, works on any device, easily deployed to cloud. Blazor lets your C# logic run in the browser — so you keep the .NET ecosystem while gaining full web reach.

Good for: Customer-facing apps, multi-site access, cloud deployment targets

Desktop Now, Web Later

Modernize the runtime and libraries first — quickly eliminating security risk and talent risk — then migrate forms to web incrementally. Reduces initial project scope while giving you a clear roadmap to full web.

Good for: Large codebases, budget-constrained timelines, risk-averse organizations

Why VB6 Has the Highest Urgency

Risk: High Immediate action recommended
  • VB6 runtime ships with Windows but receives ZERO security patches
  • The VB6 IDE does not run on Windows 11 ARM — new developer machines can't even open the project
  • COM/ActiveX dependencies are 32-bit only — conflict with 64-bit OS and applications
  • Finding a VB6 developer today requires paying a premium for a shrinking pool of aging specialists
  • Microsoft deprecated VBScript (VB6's scripting cousin) in 2011; VB6 itself has had no updates since 2008
  • Every year without action compounds your technical debt and makes migration more expensive
