Returning dynamic array from C++ DLL to VB

[CK938]

Hi,

I was hoping someone could help me return a dynamic array from a C++ Dll to VB.

Here's a simple example.

double * TestFunction(int count)
{
     double* temp = new double[count];

     for (int i = 0; i < count; i++){
          temp[i] = i;
     }

     return temp;
}

Basically I want to return an array that holds more than 1 value back to VB.
Is there a better way to do this?
Perhaps using a void function and somehow passing in the pointer by ref?

Any help will be much appreciated.


Thanks.

You need to convert your array to a safearray then return it back to VB
