Question

I want to pass a managed array from VB.NET to a function in a VC++ project. How would I declare my C++ function and how would I use the array when I’m inside it? Specifically, I want to make VB compatible functions like the one below, which is written in plain old C.

void Vcopy(double *A, double *B)
{
    int n;
    for(n=0;n<3;n++)
    {
        B[n]=A[n];
    }
}

Maybe some kind soul could convert this to something that would play nicer with VB. Thanks!

Answer 1

Can the C++ method be managed, e.g., C++/CLI ?
If so, then:

void Vcopy(array<double> ^A, array<double> ^B)

By the way, the rest of the method should be identical, provided that the size is 3 – otherwise use A->Length and B->Length.
