Common questions
Frequently Asked Questions
How do I convert Delphi to VB6?
Paste your Delphi code into the input box, confirm the languages are set to Delphi and VB6, and click Convert. CodeConvert AI analyzes your Delphi code and generates equivalent VB6 code in seconds, preserving the original logic and structure.
What are the main differences between Delphi and VB6?
Delphi and VB6 differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Delphi construct to its closest VB6 equivalent. See the comparison table below for the key differences between Delphi and VB6.
Is the converted VB6 code accurate?
The AI produces high-quality VB6 code that preserves the behavior of your original Delphi code and follows VB6 conventions. It handles common patterns, data structures, and idioms for both Delphi and VB6. For large or performance-critical code, review and test the VB6 output before using it in production.
Can I convert an entire Delphi project to VB6?
You can convert Delphi files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Delphi to VB6. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
