VFP arrays are not real binary arrays, so no you can't call DLL functions with an array parameter directly. However, you can simulate the array with a properly padded string that contains the elements in the right binary order.

>We are trying to call a DLL (written in ADA) that takes arrays as parameters. It doesn't modify the arrays, it just takes them as input parameters. I've done some searching and found that you can't pass arrays to DLLs directly from FoxPro. However, I did see some mentions of being able to use a string in place of the array. I haven't seen any examples of doing this, so I was wondering if anyone has done something like this in the past and could give me a hand, if it is even possible.
