Many differences exist between unmanaged C++ and .NET-based C++/CLI (also called managed C++). One difference between unmanaged C++ and C++/CLI is the syntax. Although this Help shows the syntax for C++/CLI only, SOLIDWORKS supports both unmanaged C++ and C++/CLI.

To help you transform C++/CLI syntax to unmanaged C++ syntax, examine the examples in the following table. The same example is written in unmanaged C++ and C++/CLI code.

Example	Code
Traverse Features	Unmanaged C++ C++/CLI
Traverse Configurations	Unmanaged C++ (demonstrates a BSTR* C-array) Unmanaged C++ (demonstrates a VARIANT array) C++/CLI (demonstrates an array)
Select Objects	Unmanaged C++ C++/CLI

To learn more about the differences between unmanaged C++ and C++/CLI, SOLIDWORKS recommends that you consult the internet and books containing information about their differences.

Search 'Unmanaged C++ and C++/CLI Code Differences' in the SOLIDWORKS Knowledge Base.
