I have a Server written in VC++ which contains a collection
called Sets. I'm having trouble using the Add method.

Type library definition:
  [id(3)]
   HRESULT Add([in] BSTR name, [in]SetObjectType type, [in]SetOptionType
otype, [in]VARIANT list, [out, retval]_IDualSetItem** prop);

Note:  SetObjectType and SetOptionType are enums.
            list is meant to hold a SAFEARRAY.

VB code:
    Dim list(1 To 2) As Integer
    Dim SCSets As MyApp.Sets
    Dim SCSet As MyApp.Set

    Set SCSets = MyApp.Sets

    list(1) = 2
    list(2) = 4
    Set SCSet = SCSets.Add("set1", stPoint, sotList, list)

The above line generates Run-time error 13 "Type mismatch error".
I suspect it is because of the array.  What's the correct method for
passing an array?

Thanks,
Drew

dim var as VARIANT
var = list
Set SCSet = SCSets.Add("set1", stPoint, sotList, var)

your list looks more like SAFEARRAY(int), not a VARIANT. I do not know if VB
will convert behind the scenes for you. Did you ever get into C++ method?
"Type Mistmach" can be caused by failing QI when Set is done.

I gave that a try but still get the Type Mismatch error.
I never actually get to the C++ code, so it's not a failure
of the method.  Any ither ideas?

Thanks,
