The current version (18-May) could not load in Windows at all, so I cannot
test that version.
Testing the last version (17-May), I found that the error is generated when
it executes this line of code:

for ($rowcount = 0; !$rs->EOF; ++$rowcount, $rs->MoveNext()) {

Specifically, it is the condition ( $rs->EOF ) that causes the Access
Violation. All else works ok.
$rs->EOF should return a boolean datatype.

MSXMLParser also still causes Access Violation when calling

When running PHP as CGI (for the MSXMLParser script), I get this Application
Error message:
"The instruction at "0x1008d824" referenced memory at "0x3c0a3e64". The
memory could not be "written"."

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
"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

cgi or the isapi version ?
