Does anyone know a CLI command that can do this? Just the command or an idea would do, I just need a better starting point.

No, not all controls can be double buffered

A C++/CLI program with a function that takes a string as an argument, writes it into every entry of an array of length 5, and returns that array to the caller.

typedef array<System::String^> StringArray;

Certainly not a homework question

I'm not developing this specifically in Visual Studio though, I was just compiling with cl and csc. Which is why I was wondering if someone could explain how to explicitly link the two.

I suppose I just had something wrong in the C++/CLI file.
