FAQ
Q: Are entire projects converted?
You can select VB projects or folders to convert. All ".vb" files within that project or folder will be converted and output as either traditional .h/.cpp files or C++20 modules to the directory you specify. However, VB to C++ Converter does not construct the new C++ project file. This is due to the lack of similarity between VB project types and formats and C++ project types and formats.
Q: Are VB.NET delegates converted?
Yes - try out our Free Edition to see the conversion details. VB to C++ Converter converts VB delegates to function pointers using std::function.
Q: Are the original VB.NET files altered in any way?
Your existing code is left completely intact. The new C++ files are output to the new location that you specify.
Q: What about .NET UI code?
The converter does not convert .NET UI types due to the lack of similarity between these types and C++ UI types.
Q: What is the conversion accuracy?
Our accuracy is very high, but there will be significant adjustments required for all but the simplest conversions. There are no direct equivalents for some aspects of VB.NET. Read the rest of the FAQ to get an idea of a few things that are not converted. VB to C++ Converter is intended to reduce the amount of work you'll have to do to convert code to C++, but it is just the first step.
Q: Are VB6 projects converted to C++?
No - the most effective way to convert VB6 to C++ is to first upgrade to VB.NET, and then use VB to C++ Converter on the resulting VB code.
Q: Is there an option to produce C++/CLI code?
No. Despite the name, C++/CLI has very little in common with C++.
Q: What are the most common manual adjustments?
- VB to C++ Converter converts only some .NET types to C++ equivalents. The converter offers options to use your own custom replacements.
- VB to C++ Converter cannot ensure proper deallocation of pointer variables. In some cases, a call to the delete operator is made, but in general complete memory deallocation is not included in the conversion. However, the converter contains options for converting to smart pointers.
- VB to C++ Converter comments out attributes and events since there is no direct C++ equivalent to .NET attributes and events.
- There will be occasional qualifier symbol adjustments required. For example, it is possible that the converter fails to determine whether a particular VB dot operator should be replaced by a C++ arrow, double colon, or dot. If type analysis fails to determine the equivalent, heuristics are used to determine the most probable equivalent.
- VB to C++ Converter cannot convert 'finally' clauses since there is no acceptable C++ equivalent.
- If the VB project did not have 'Option Strict On' set, then you'll likely have a number of cases where different types are compared with each other - the converter will sort out most cases, but some may need adjustment.
- Although some On Error GoTo statements are converted, some elements of classic VB unstructured error handling (On Error Resume Next, On Error GoTo -1, etc.) are not converted. These statements are marked as a 'task'. Also, all references to the VB Err object are not converted and marked as a 'task'.
- 'When' statements in 'Catch' blocks (which have no equivalent in C++) must be manually adjusted. These are commented out and combined with a warning comment.
