hi,

Sorry If i am repeating . Any dimension of array can be packed as Variant and
sent to VB. If U are using any custom interface i.e. Derieved from IUnknown,
it will not be visible to the VB client.  But it can be seen through the
C++/VC++ client. An example in VC which creates an array of variants (single
dim.)

GetArray(VARIANT *varArr)
{
VARIANT varArray;
varArray.vt = VT_ARRAY | VT_VARIANT.

SafeArrayCreate(varArray.parray, dim,...)
*varArr = varArray;
// And use SafeArrayPutElement and SafeArrayGetElement to put and get data
}

and in vb
dim x as new obj
dim v as variant
obj.getArray(v)
' Access the array
msgbox v(0)...

Sorry I am not weel versed with VB.
Otherwise, u can send with a size_is parameter.

Regards
Shankara Narayanan
