Hello,
I am trying to get the value of the Auto-Incremented key that was assigned
using LAST_INSERT_ID( ). However, when I execute the following PHP statements
after the insert I only get: "value of entryID: Resource id #7" after EVERY
insert (it never changes).
What am I doing wrong?
Thanks very much!
Vic
............... ............... .
$_SESSION["entryID"] = (mysql_query ('SELECT LAST_INSERT_ID( ) FROM
tblShowEntries' ));
$entryID = $_SESSION["entryID"];
echo "value of entryID: $entryID"; 3 41663

The return value of mysql_query is *NOT* the value for last_insert_id( ).
Fetch a row (e.g. using mysql_fetch_row ) and then look at the column
you want, and *thats* the value you are looking for.

Thanks Gordon,
The following code seems to work fine ....
$query = "SELECT LAST_INSERT_ID( )";
$result = mysql_query($qu ery);
if ($result) {
$nrows = mysql_num_rows( $result);
$row = mysql_fetch_row ($result);
$lastID = $row[0];
$_SESSION["entryID"] = $lastID;
}

Please note that the PHP function mysql_insert_id () will return the
same as you're trying to fetch.
$lastID = mysql_insert_id (); http://php.net/mysql_insert_id

I have a *.cer file, a public key of some one and I want to encrypt some

Can someone point me to a sample code for Encrypting some file using

The real part is Encrypting using X509Certificate and CryptoServiceProvider.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
