Common questions
Frequently Asked Questions
How do I convert Delphi to VB.NET?
Paste your Delphi code into the input box, confirm the languages are set to Delphi and VB.NET, and click Convert. CodeConvert AI analyzes your Delphi code and generates equivalent VB.NET code in seconds, preserving the original logic and structure.
What are the main differences between Delphi and VB.NET?
Delphi and VB.NET 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 VB.NET equivalent. See the comparison table below for the key differences between Delphi and VB.NET.
Is the converted VB.NET code accurate?
The AI produces high-quality VB.NET code that preserves the behavior of your original Delphi code and follows VB.NET conventions. It handles common patterns, data structures, and idioms for both Delphi and VB.NET. For large or performance-critical code, review and test the VB.NET output before using it in production.
Can I convert an entire Delphi project to VB.NET?
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 VB.NET. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert VB.NET back to Delphi?
