Does anybody know how to pass an entire array as a parameter in a COM
component method?

I am trying to pass an array of filenames.  The COM component is a MTS
component written in VC++.  I found some help on the MSDN cd that mentioned
that to pass an entire integer array just pass the 1st subscript like
strFiles(1).  When I do that with my string array then my component crashes
every time I access the second subscript in the com componet. re is a
snippet of my asp code and the error msg I receive in the browser:

<% Option Explicit

dim objTest
dim strFiles(2)
strFiles(1) = "c:\\temp\\test.dll"
strFiles(2) = "c:\\temp\\hello.txt"
call objTest.exeCabMgr( strFiles(), 2, "c:\\temp", 10000, "100", "" )

Error Message:
Microsoft VBScript runtime error '800a0009'

Subscript out of range

/test.asp, line 18

If I pass the first subscript then I crash in my mts component:
dim objTest
dim strFiles(2)
strFiles(1) = "c:\\temp\\test.dll"
strFiles(2) = "c:\\temp\\hello.txt"
call objTest.exeCabMgr( strFiles(1), 2, "c:\\temp", 10000, "100", "" )

Thanks in advance!!!

Arrays in ASP are zero based, so if you dim(2), use strFiles(0)
strFiles(1)

You need to use SAFEARRAYS.  The help from MSDN you're quoting only works
when the object being passed the array is in-process.

The IDL for the C++ COM component needs to have a method defined as:

[helpstring("method PassArrayOfFileNames")]
PassArrayOfFileNames([in]SAFEARRAY(BSTR) fileNames);

(fileNames may have to be a *fileNames - can't remember off the top of my
head - if you get errors compiling / referencing it from VB then try
changing to *)

The C++ method is:

STDMETHOD(PassArrayOfFileNames)(/*[in]*/SAFEARRAY *fileNames);

[Note that it needs one more * than the IDL]

In VB you can call it as follows:

Dim f(0 to 4) as String
f(0) = ...
f(1) = ....

etc

' Assume x is the object implementing the method above
x.PassArrayOfFileNames(f)

In the C++ code you will need to use the SAFEARRAY structure and APIs to
access the data. I wrote a wrapper class that makes it easier to use' if
you're using MFC then there's a CSafeArray you could try.
