I am attempting to call a function on the RightFax API from VB.NET.  The
original declaration for the function in VB 6.0 is:

Declare Function RFVB_SendFiles1 Lib "RF2VB.DLL" (ByVal hServer As Long, _
                                                 ByVal lFI10Object As Long, _
                                                 ByVal lNI10Object As Long, _
                                                 ByVal fSendWithCover As
Boolean, _
                                                 sCoverSheetModel As
String, _
                                                 aFiles() As String, _
                                                 hNewFax As Long) As Long

When translated to VB.NET the declaration looks like:

Declare Function RFVB_SendFiles1 Lib "RF2VB.DLL" (ByVal hServer As Integer, _
ByVal lFI10Object As Integer, _
ByVal lNI10Object As Integer, _
ByVal fSendWithCover As Boolean, _
ByRef sCoverSheetModel As String, _
ByRef aFiles() As String, _
ByRef hNewFax As Integer) As Integer

I call the function with the line:

lError = RFVB_SendFiles1(hServer, lFI10Obj, lNI10Obj, 1, "", aFiles, lHandle)

where:

·    hServer is an integer
·    lFI10Obj is an integer
·    lNI10Obj is an integer
·    aFiles is a string array of 8 elements with only the first element set to
a value.
·    lHandle is an integer

Whenever I hit the call I get an error message back from the DLL about an
invalid parameter.  Could I be violating a word boundary or not initializing
the string array correctly?  I’m stumped.
