works here.
the only mistake i found was, that if either the connect string or the query was wrong
$conn->execute() returned a nullpointer instead of a valid recordset.
this only produced a warning so there was a nullpointer exception at the first attempt
to access $rs->...
now i produce an error (unfortunatelly this causes the script to stop).
i'll fix this in the code and switch back to a warning, but i think it's ok for now.

Here is a code snippet for testing ADODB:
<?php
define ("DSN_USER", "sa");
define ("DSN_PWD", "");
define ("DB_SERVERNAME", "localhost");
define ("DATABASENAME", "Northwind");
define ("OLEDB_CONNECTION_STRING", "Provider=SQLOLEDB; Data Source=".DB_SERVERNAME.";
Initial Catalog=".DATABASENAME."; User ID=".DSN_USER."; Password=".DSN_PWD);
$conn = new COM("ADODB.Connection") or die("Cannot start ADO");
$conn->Open(OLEDB_CONNECTION_STRING);
$command = "SELECT * from employees";
$rs = $conn->Execute($command); // Recordset
$num_columns = $rs->Fields->Count();
$this->set_arr($num_columns);
for ($i=0; $i < $num_columns; $i++) {
$fld[$i] = $rs->Fields($i);
}
$rowcount = 0;
while (!$rs->EOF) {
for ($i=0; $i < $num_columns; $i++) {
$arr[$i][$rowcount] = $fld[$i]->value;
}
$rowcount++; // increments rowcount
$rs->MoveNext();
}
$rs->Close();
$conn->Close();
$rs = NULL;
$conn = NULL;
?>
This produces the error: PHP has encountered an Access Violation at 2474FF04
You can also produce an Access Violation by trying to use MSXML Parser 3.0,
and by calling the loadXML() method.
I downloaded php 4.0.6-dev [2001-05-04] build from
php4win32.sourceforge.net/releases/php-4.0.6-dev-20010504.exe

are you using the cgi or the isapi version ?

Same bug, access violation using ADODB and MSXML Parser,
but using a 4.0.6 build, dated 2001-05-04.

This is now fixed in CVS. Fix will be in 4.0.6.
