Description: COM does not support variant type 1 (NULL)
Here's hoping for a quick fix :-) PHP 4.03pl1 also exhibits the above bug.
Just tested COM again and discovered variant type 6 (currency) is not supported either.
Thanks again.

Currently, COM does not support variant type 1. This is type NULL.
This should be easy to fix as we can make it equivalent to false. Does PHP support null as a
constant?
The bug can be replicated by accessing a database with nulls in the records using ADO.
<?
$dbc = new COM("ADODB.Connection");
$dbc->open ("driver={Microsoft Access Driver
(*.mdb)};dbq=d:/test/DB/guestbook.mdb;uid=Admin");
$rs = $dbc->Execute("select * from guestbook");
$i = 0;
while (!$rs->EOF) {
$i += 1;
$fld0 = $rs->Fields(0);
$fld1 = $rs->Fields(1);
$fld2 = $rs->Fields(2);
print "$fld0->value $fld1->value $fld2->value<BR>";
$rs->MoveNext();
}
$rs->Close();
?>
