About the technology
What Visual Basic is
Visual Basic is Microsoft’s event-driven programming language for creating Windows applications and business automation. Visual Basic .NET extends the language through the .NET platform, while Visual Basic 6 remains present in many established desktop systems. VBA, or Visual Basic for Applications, is used inside Microsoft Office to automate repeatable work.
Where it is used
Visual Basic supports practical software that connects people, data and operational processes. Typical assignments include:
- Maintaining Windows desktop applications for internal teams
- Automating Excel, Access, Word and Outlook workflows with VBA
- Connecting business software to SQL Server and other databases
- Extending legacy systems while preparing a controlled migration
- Building forms, reports and data-entry tools for operations
Ecosystem and tooling
Strong specialists understand the Visual Studio environment, .NET libraries, Windows APIs and database access patterns such as ADO.NET. They may also work with Microsoft Access, Excel object models, COM components, XML, REST APIs and source control. For older applications, knowledge of Visual Basic 6 runtimes, ActiveX and deployment constraints is often essential.
When companies need support
Companies bring in freelance expertise when a critical desktop application needs reliable maintenance, a VBA process has become difficult to govern, or internal knowledge is no longer available. In Cologne, this can matter to manufacturers, logistics teams, insurers and other organizations with long-running operational software. Remote work is practical, while on-site workshops can help with system discovery and user acceptance.
What strong professionals deliver
Quality starts with careful reading of existing forms, modules, dependencies and database queries before changes are made. Experienced professionals separate business rules from interface code, add meaningful tests where possible and document deployment steps. They also know when to preserve a stable Visual Basic 6 application, when to refactor it in VB.NET and when another technology is the safer choice.
Skills to assess
Look for evidence of completed work with the relevant Visual Basic edition, not just general .NET knowledge. A capable specialist can explain error handling, data access, authentication, version control and release procedures in plain language. Ask how they would secure macros, protect sensitive data, reduce fragile dependencies and hand over maintainable source code to your team.
Frequently asked questions
Quick answers to the questions that come up most around Visual Basic.
Visual Basic is used for Windows desktop applications, internal business tools and Office automation. VB.NET supports applications on the .NET platform, while VBA is common for Excel, Access and other Microsoft Office workflows.
Visual Basic .NET and C# use the .NET platform and can access many of the same libraries. C# is more common in new development, but Visual Basic can be a practical choice when a team already has working code, domain knowledge or extensive Office automation.
A strong Visual Basic specialist often brings SQL, relational database design and Microsoft Office automation skills. Experience with Windows APIs, REST services, COM, source control, testing and migration planning is also valuable for business systems.
The right level depends on the system’s condition and risk. Visual Basic maintenance may require someone who can trace undocumented dependencies and work safely with legacy components, while a contained VBA change may need narrower expertise and clear acceptance tests.
Visual Basic work can usually be completed remotely when the specialist has secure access to repositories, test environments and representative data. For Cologne teams, occasional on-site discovery sessions can help when the application depends on local devices, undocumented processes or close user collaboration.
Visual Basic 6 can remain stable and valuable when it supports a critical process and replacement would create unnecessary risk. Maintenance should include dependency mapping, controlled releases and a realistic modernization plan rather than an untested rewrite.
Ask a Visual Basic specialist to explain how they inspect existing code before changing it. Review their approach to error handling, database queries, security, automated testing, deployment, documentation and rollback, then use a small paid technical task to confirm it in practice.
Visual Basic specialists working with Cologne-based companies should be comfortable discussing requirements in the team’s working language and handling business data carefully. Remote collaboration can work well, but professionals should clarify access controls, documentation expectations, support windows and any need for on-site coordination.
