udat and objects
Hi! Is it correct, that it is impossible to store blessed references (Perl objects) in udat? Same for mdat? If yes, is there any workaround? Maybe serializing the object first with Storable or something like this? But if i interpreted the mails in the archive correct this still will not work with DBI-Connections? Is there a way to use only one DBI-Connection for the whole application?

I'll give you some suggestions and maybe others may complement it.
I think tha what you mean with "only one DBI-Connection for the whole
application" is in fact one DBI connection for each Apache child.
There are some ways to do these but the most common is to use Apache::DBI.
It will do the caching for you. So write a page (component) that starts
the connection and put it back in the $req_rec reference so it will be
available to all other Executed pages in the same request.
Example:
connect.epr:
[-
$req = shift;
$req->{dbh} = new DBI(...);
-]
In your pages:
[-
Execute('connect.epr');
$req = shift;
$dbh = $req->{dbh};
# Database stuff...
-]
In other Executed parts:
[-
$req = shift;
$dbh = $req->{dbh};
# More database stuff
-]
This is a simple method and of course there are more elegant approaches
you could try.
About storing objects in udat I usually avoid it, its better to store
simple variables.
If you need objects you have to make shure the serialized data are not
bigger than the capacity of the column in your database (usually 32k).
Good luck,

called from embperl? $0 available?
Hi! I noticed, that $0 is set to "-e" in my module if it is called from embperl. Is this the normal behaviour or just random? Is there another - possible better - way to determine in my modul, if the function is called from Embperl or from an ordinary script? Thanks for any help! (and thanks for the helpful answers to my other question :-) Benni -- http://www.aymargeddon.de - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Try this inside your function:
# tested on HTML-Embperl-1.3.4
if ( (caller)[0] =~ /^HTML::Embperl::DOC::_\d+$/ ) {
# was called from Embperl
} else {
# was called from elsewhere
}

That might be possible

TRy
[$ var %CLEANUP $]
$CLEANUP{'udat'} = 0 ; # udat without $
I didn't tried it out, but it might work

Simple table problem
I know this is a really simple problem - and can be fixed using if statements etc - but wanted to know if there was a standard way of doing this. Simply say I have a array @array = qw/1 2 3 4 5 6 7 8 9 10/; And I want to create a dynamic table of this data - BUT I want to have a fixed column length (in this case 4). The end table should look like 1 2 3 4 5 6 7 8 9 10 Using the dynamic table syntax and the associated magic variables - can this be achieved - or do I have to add some custom code ? Have checked out various examples and searched the mailing list but seems either it cant be done this way or I am yet again missing the point.
