    Marshal to pass a long pointer to an array of short?

    How do I pass a variable length array of short values to an API call? I have tried
    VB Code:
    1. <MarshalAs(UnmanagedTypes.LPArray)>pFields() As Short
    but it generates a loadlibrary exception...

    Any ideas?

    Thanks in advance,
    Duncan

    Have you tried using a fixed length array?

    Code:
    <MarshalAs(UnmanagedType.LPArray, SizeConst=10)>pFields() As Short

    ok, but just to see the result, is it possible for you to test if it works with a fixed length array?

    Some situation requires a fixed length array, that would help us see if that might be the case for you.
