Questions about passing arrays.

I am working on a fortran dll where i want to pass a string array from an aspx page written in vb.net to my dll. Passing the string array to the dll from MS Access works perfectly, but when i call the dll from the aspx page, I get a NullReferenceException error.
I know that
1. The dll gets control
2. I have a subroutine that converts the string array from a SafeArray to usable string data for manipulations in the dll, which works from MS Access.
3. It is in this routine where the dll "crashes"
It seems to me that the data is passed differently from aspx than it is from MS Access. Does anyone know what the difference would be? I would like to use my dll from both Access and aspx.
