Hello,
I have setup a table with 1 row and 2 columns.In the 1st, I have a
iframe that displays tons thumbnails of images. In the next I have an
image (enlarged). When the user selects a thumbnail it displays the
enlarged image in the 2nd column. This work quite nicely.
Where I need some help is with the fact that each image has an entry
(description in a database table). How can I display the entry when
the image is updated. The image gets updated using javascript but the
page itself is php (as is the rest of the site). I do not want to
reload the page everytime (long and waste of badnwidth).
Thank you for your guidance,
Daniel

One way is to have an array of the info built with an entry for each of the
thumbnails. In the second column have the info for that array entry appear
along with the enlarged image.
Shelly,
I had this in the back of my head, but do not know how to approach
it. How can you build an array in memory an change the text
accordingly. Any chance you could give an example?!
Thank you,

Show us your code for that page. It would make things easier for people to
help. Specifically, exactly what code are you using to refresh the enlarged
image area?
In **general**, one way to build the array (put in your appropiate error
checking, of course) is:
$res = $mysql_query("t he_query_string ", the_db_handle);
$numElementInAr ray = mysql_num_rows( $res);
$theArray = array();
for ($i=0; $i<$numElementI nArray; $i++) {
$row = mysql_fetch_arr ay($res);
$theArray[$i] = $row['identifier'];
}
Then in the appropriate field in the html area you might have something
like:
<p><?php echo $theArray[$i]; ?></p>
where, of course, $i corresponds to the index of the particular thumbnail
selected (its value).
More or less, this is the kind of thing you would be doing.
I found a method, maybe not the best, but it is functional. I simply
generate the page while adding a 2nd variable to the onclick event for
each image where I place the description. Then mod the onclick event
to populate the innerHtml for the element.
Only issue is the 2nd variable can be up to 255 chrs. If you have
another method, I am all ears!
Thank you,

Hi All,
When a table is linked to a form, Access normally updates the entire table
when that record is closed. The fields don't get get updated in the table
as they become changed.
I've got multiple users accessing my database, so I need the fields in a
record to be updated immediately when they change. I cannot wait until the
user closes that record for the fields to be updated, as other users will
be using old data.

I'm a little nervous about slamming my database with a dozen Update queries
in a loop that all modify RecordSources of open forms. Will the use of

Should I include a Requery in the loop after executing each query?
For example:

Hello.
I have a listbox whose rowsource is set to a saved query (call it
"qry_customer_list.") When I add customers to my database, I call the
listbox Requery method so that the listbox will display the customers that I
added. Unfortunately, the listbox display does not change. If I close the

Any suggestions on how to fix this?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
