About the technology
Visual Basic work
Visual Basic is still widely used in business software that must stay stable and easy to maintain. It shows up in internal tools, desktop apps, Excel automation, Access databases, and older VB6 or VB.NET systems that continue to support daily operations.
Typical tasks
- Update legacy Visual Basic code without breaking core workflows
- Build or adjust forms, reports, and internal tools
- Connect VB solutions to databases, files, and APIs
- Automate office tasks with VBA in Excel or Access
- Stabilize old applications before a larger migration
Skills that matter
Strong professionals know the difference between classic VB6, VBA, and VB.NET, and they understand how each behaves in real projects. They write clear code, handle COM and Windows integration, and keep maintenance simple for the next person who touches the system.
Ecosystem and tools
Visual Basic projects often sit close to Microsoft technologies. Common work includes Visual Studio, .NET, SQL Server, Access, Excel, COM objects, and Windows desktop components. In Dusseldorf, this is especially relevant for companies with long-running back-office systems and teams that need reliable support in German or English.
When companies need help
- A key application is old, but still business critical
- An Excel or Access solution has grown too complex
- A migration to .NET needs careful planning
- The team needs help reading and changing legacy code
- Support is needed for both remote work and on-site sessions in Dusseldorf
Good results
A good Visual Basic specialist documents changes, keeps interfaces predictable, and avoids unnecessary rewrites. The best work improves stability first, then adds features only where they create clear value. That is what keeps VB software useful while the wider system evolves.
Frequently asked questions
Everything clients usually want to know about Visual Basic, in one place.
Visual Basic is used for internal desktop tools, form-based apps, office automation, and legacy systems that still support daily work. It is also common in VBA macros for Excel and Access, where teams need quick, practical automation rather than a full rebuild.
The right choice depends on the system you already have. Visual Basic often means classic VB6 or VB.NET, while VBA is the macro language inside Microsoft Office. A strong specialist can tell whether you need maintenance, extension, or a gradual move to .NET.
Visual Basic is usually chosen to keep existing Windows and Microsoft-based solutions running with low disruption. C# is often the closer long-term direction inside .NET, but a rewrite is not always the best first step. For stable legacy software, preserving business logic can matter more than changing the language.
A strong Visual Basic freelancer usually knows SQL, Excel, Access, Windows forms, COM, and basic API integration. For VB.NET work, .NET, Visual Studio, and testing habits are also important. The best experts can work across code, data, and user-facing screens.
For a small macro fix, a focused Visual Basic specialist may be enough. For legacy applications, migrations, or systems with several dependencies, you want someone who has handled maintenance and refactoring before. The more business critical the code, the more important that hands-on history becomes.
Yes. Many Visual Basic tasks can be handled remotely, especially code review, bug fixing, documentation, and VBA work. On-site time in Dusseldorf can still help when a project involves sensitive systems, local stakeholders, or older environments that are hard to access remotely.
Look for clear explanations, code that is easy to maintain, and a careful approach to risk. A strong Visual Basic expert should be able to describe the current architecture, point out weak spots, and propose changes that fit the system instead of forcing a redesign.
Common reasons are aging VB6 applications, fragile Excel automation, Access databases that have outgrown their original design, and VB.NET systems that need updates. Visual Basic specialists are valuable when the software still works, but the team needs safer changes, better structure, or a migration path.
