Message-ID: <3F7D5349.5020906@wimba.com>

Java Swing provides many powerful, pluggable components. For example, 
there's a virtually ready-made web browser. Does anyone know if there's 
a component that provides a web-processing interface, that is, an 
interface that allows a user to enter text of different sizes, colors, etc.?

Failing that, does anyone know of an open-source Java program that 
provides such an interface?

Would anyone happen to know how to make this into an a href so that it 
links to another php page?


this is the block of info that is called to a table on a web page:
     <tr>
       <td><div align="center"><?php echo $row_Grade['c_code']; 
?></div></td>
	  <td><div align="center"><?php echo $row_CourseTitle['title']; 
?></div></td>
       <td><div align="center"><?php echo $row_Grade['section']; 
?></div></td>
       <td><div align="center"><?php echo $row_Grade['grade']; 
?></div></td>
       <td><div align="center"><?php echo $row_Grade['absences']; 
?></div></td>
       <td><div align="center"><?php echo $row_Grade['speed']; 
?></div></td>
       <td><div align="center"><?php echo $row_Grade['w_date']; 
?></div></td>
     </tr>

the first line where it says $row_Grade['c_code'] I need to be a 
hyperlink to this a page that calls this information
CourseDetails.php?code=$code&term=$term&year=$year&course=""

I thought maybe
<a href=CourseDetails.php?code=$code&term=$term&year=$year&course=""> 
<?php echo $row_Grade['c_code']; ?></a>

was perhaps the answer but I keep getting error messages, can anyone 
shed any light on this?

Thank you : )

And thanks to everyone who made recommendations for php books, picked 
up a couple and they've
helped : )  But talk about swimming up stream : )

what you probably want is:

<?php 
echo '<a href="CourseDetails.php?code=' . $code . 
     '&term=' . $term . '&year=' . $year. 
     '&course=' . $row_Grad['c_code'] .
     '>' . $row_Grad['c_code'] . '</a>';
?>

although I might have misunderstood and you may not want 
	'&course=' . $row_Grad['c_code'] .
as you may want to leave course blank.

To set course to blank, just don't mention it.  It's not particularly
easy to set it explicitly to empty string in a GET string.  This is why
you often see code like:

if(defined $code && $code ne "")
{
}

although that's Perl, and the semantics in PHP may be subtly different.

If this doesn't answer the question post more code and include your
error messages

G'day Wolf,

While I'm happy to help people I'd prefer to keep such correspondance on
the list as then everyone can learn.  Please refer all questions to the
list rather than to me directly.

How bizarre.  I can see one error, I forgot to close my "s inside the
html.  It should have been:

<?php
	echo '<a href="CourseDetails.php?code=' . $code .
	      '&term=' . $term . '&year=' . $year.
	      '&course=' . $row_Grad['c_code'] .
	      '">' . $row_Grad['c_code'] . '</a>';
?>

How about you print the above URL to STDERR too and see what it's
building.  As for the unexpected ; without seeing exactly how you used
my code (and I couldn't see it in your code) I can't even hazard a guess
why it's unhappy.

If you don't know this then I'm probably not going to know either.  Why
don't you see if you can approach the problem from another side and see
if you can get a simple script working and then when you know that that
works, see if you can incorporate the relevant pieces into your
script...?   Something like this perhaps:

<?php
	$term = 1;
	$year = 2;
	$row_Grad['c_code'] = "123";

        echo '<a href="CourseDetails.php?code=' . $code .
              '&term=' . $term . '&year=' . $year.
              '&course=' . $row_Grad['c_code'] .
              '">' . $row_Grad['c_code'] . '</a>';
?>

If that works then you know the problem is somewhere else...

all the best,

At my work, there's a printer. It's that damn GDI printer that's marked "Paperweight" at linuxprinting.org, but my boss doesn't want to replace it for now. It's Lexmark Z23.

I've got a driver from Lexmark. Unfortunately, the newest driver is for US (as I suspect), because no matter what paper size you feed to it, it prints everything as on Letter paper (although it's in fact rescaled on an A4). However, it sucks less, but sucks, no matter what you do. 

Finally, it's got itself to work as I want - I mean, to work at all. But sometimes I have to reinstall the software, as there is no point to tweak (z33 filter simply hangs itself sometimes). What I'm looking for is: did anyone ever reverse engineered output data for Lexmark Z23 printer, in order to write something of driver or utility for it? Lexmark has libraries (object only) for Z55, but I'm unaware of it's (in)compatibility with Z23-Z33. Maybe, if I ever decrypt printer commands, the new filter or Ghostscript device will appear... Dunno. But if someone ever did it, please let me know.

I have mixed feelings about Lexmark's native drivers and libraries. They suck. I don't know how and why. And if they work, I also don't know anything about it. Printer is OK, I've sent .out files to it and it worked. It is the filter that hangs mysteriously, from time to time, like M$ Windows does.

Thanks in advance.

All you need for your table is a count of days in attendance rather than all
you've asked for.  Something like:

select dayname(date), count(*) from attendance 
where date between '2003-09-01'and '2003-09-05'
group by dayname(date);

will give you a list like:

Tuesday	  |  3
Wednesday |  2
Thursday  |  3
Friday    |  1

Now all you need is to parse that and print in your horizontal format.  Of
course, you need to handle 's_code' also.  Once you start building pivot
tables, sql isn't enough and you have to start looking at a program.  I
found it best to use sql to get your first example as output to file and
then use a separate program to do the pivat table bit on the datafile.

Message-ID: <200310152238.41301.suzo@bigpond.net.au>

I am looking for a VRMLviewer for linux, so far I have found a few that are in 
early stages of developement, (though seem to have been in the same state for 
some years!) but there have been problems trying to get them to install on my 
system (Mandrake 9.1).

Does anyone have a VRML veiwer working, can you tell  me where to obtain it?  
And were there any problems with installation.

Once that is organised I will want to try and learn VRML, I know that there 
are some VRML modellers on developement/ or available. WHat do you think of 
these?  Are they worth the trouble, is it easier/better to start with doing 
things by hand.  (This is my inclination, but I don't know what I am doing 
and the book that I have doesn't address these issues!)

thanks

does anyone happen to see any obvious mistakes?


here's the code:

			$grid[$i][$j][$k] = "";

	}
}




// build query

At first glance I don't see any problems with how you're retrieving the 
information from the database, but you seem to have commented out a required 
piece of code before you start printing all of the data:

	// retrieve result set
	$result = mysql_db_query("db",$query);
	//$numrows = mysql_num_rows($result);

	// loop thru result
	for($crow = 0; $crow < $numrows; $crow++) {

Without having $numrows set, the for loop is never executed, which in turn 
results in you having no data to output to your table. Hope that helps.

I think in the loop I need some sort of additional if statement to tell 
it which row to choose, would anyone
happen to know how to construct this if statement?




// loop thru result
for($crow = 0; $crow < $numrows; $crow++) {
	$res_array = mysql_fetch_assoc($result);
	$period=$res_array['period'];
	$status = $res_array['status'];
	
	

	
	

	for($i = 0;$i < 5; $i++) {
	    for($j = 0; $j < 8; $j++) {
	                                                 
<--------------------- need additional if statement here?
			if ( $grid[$i][$j][0] != "") {	
			} else {
				$grid[$i][$j][0] = $status;
			}
		}
	    }
	}


Full Code below if needed

<?php require_once('connect.php'); ?>
<?php
mysql_select_db($database_connect, $connect);
$query_Code = "SELECT s_code FROM attendance where s_code=$code";

There's a quite long list of viewers at <http://www.web3d.org/fs_faq.htm>.

Anyway, the number of browsers that run with linux seems to be about three
or four:

FreeWRL	<http://freewrl.sourceforge.net/>
Coin3D	<http://www.coin3d.org/>
VRWave	<http://www.iicm.edu/vrwave>

And there's Casus Presenter from Fraunhofer Institute for Computer
Graphics <http://www.igd.fhg.de/CP/> which requires a (non-free) license
for OpenInventor. The link to OpenInventor they provide leads to a 404
page, anyway...

I have to say that I don't know anything to say about the mentioned
browsers; it was quite a while ago when I took the VRML course at my
university, and they seemed to have accepted that graphics software mostly
focused on W*nd*ws platforms back then.

Subject: [prog] Ideas for a script
Message-ID: <20031021224141.GA28696@katspace.com>

I'm thinking of starting a mailing list which has "dues" in it, and I'd
like to write a (Perl) script(s) to keep track of the individual dates that
people's dues are due, email them reminders, and email me if they are
overdue, so that I can unsubscribe them.  And also have an easy way of
updating the data with (a) new subscribers and (b) updating when people
*did* post their dues, so that the script won't remind them if they've
already posted.  And also keep track of people who have just left, so
that they can't get around the dues requirement by unsubscribing when
they're due and then resubscribing afterwards.
I'd like to have as much of this automated as possible.

Got any ideas as to how I should structure this, any helpful modules and
so on?  Thanks.

Now, someone wrote me privately but I think they meant to go to the
list, asking...
>Could you please give us an example? Like where you want to fetch the
>data from.....etc.

And my answer is -- it's all up in the air, isn't it?  The data has to
be put *in* before it's fetched *out*, which means the data could be in
any form I choose to make it, depending on what seems to best suit the
task -- whether it's better in a flat file, in XML file, or in an SQL
database.  While the mailing list is being run on a free server over
which I have no control, I'm intending this script suite to run on
my Linux box, which means I have a lot of choice as to what to do it
with.   I've already got Postgres up and running for another database,
but I'm not sure that using Postgres for this wouldn't just be overkill,
and whether a flat file might be better.  Not sure.  Since comparing
dates is involved, then maybe a full database would be better, or maybe
just a good date module.

I don't know!  Which is why I'm asking for advice.

The tasks needed to be done are as follows:
A) input mailing list member information.  This might be done by hand,
or by parsing a "a new member had joined" email which I as the
list-owner would be sent.  This would add to the data (whether database
or flat file)
B) input when a mailing list member has posted their dues.  It would be
nice if this could be done by parsing the list mail in which they sent
their dues -- it wouldn't be hard to declare that all dues mail must
have "DUES" in the subject or something like that
C) a nightly cron job calls a script which
  a) checks the dues data and emails the list member a week (or some
other period) before their dues are due
  b) checks the dues data and emails the list owner informing that a
particular list member's dues are overdue.
D) a script to either delete or mark as left, those members who
are no longer members.

It would also be nice if one could put exemptions and extensions into
the data (file/table), so that the script doesn't make me look like a
list-nazi.

I have always found that the 'overkill' part of using a database is the
setup part, and the learning how to talk to it.  If you've already got
one running, and are familiar with how to access it, I'd say, why not?
It's much cleaner (imho) than mucking around with parsing flat file text
data, even XML formatted text.  Plus SQL is fun!

I suspect you need the SDK (software development kit). I'm not 100% sure
though, so if someone else tells you to download something else, believe
them!! :-)

I would simply get the J2SE SDK.

http://java.sun.com/j2se/1.4.2/download.html

You definitely want the SDK (not the JRE), and if you want a native Java IDE 
and you don't mind a somewhat bigger download, get the NetBeans IDE with J2SE 
cobundle.

My understanding is that J2EE is for distributed application programming, and 
(someone please correct me if I'm wrong) similar to the .NET concept.  
(Actually, that is probably completely unfair, as I'm pretty sure that the 
java distributed model predates .NET - it is just the .NET was marketed 
better.  No suprises there.)

I think each package is basically a superset of the previous.  ie, the J2SE 
SDK contains the JRE, plus all the things you need to make java class files.  
The J2EE contains the J2SE, plus extra things to make distribued application 
programming easier.

Of course, I could be completely mistaken...  (I haven't really played with 
Java for a while.  I saw the Python light instead.)

Cheers,

Rasjid.

Noir,

Afaik, J2SE and J2SDK are basically synonymous.  Perhaps someone else can
comment.  J2EE includes enterprise Java APIs (application programming
interfaces) and isn't necessary unless you start getting into server-side
web programming, web services, etc.


For basic Java programming , download J2SE 1.4.2
(http://java.sun.com/j2se/1.4.2/download.html).

Then I'd recommend the online tutorial at:
http://java.sun.com/docs/books/tutorial/

Becky

As Hamster suggested, yes you need the J2SDK if you are going to do
actual programming, as opposed to just running a program written in Java
- for which the J2SE is sufficient.  And J2EE (Enterprise Edition) is
unneccessary for simple stuff, in fact there is a growing body of
opinion that it's unneccessary at all ;)

Not surprised either that java.sun.com has confused you, it always takes
me 3 times as long as it ought to to find stuff there as well.  As a
result I have lots of java.sun.com bookmarks.

One other thing of note.  In order to run any java programs, you need to
include the bin directory of where you installed java in your path.  The
usual way is to set a JAVA_HOME variable in your environment, pointing
to the directory you installed java in, and put %JAVA_HOME%/bin in your
path.  A number of very useful tools (such as ant, a jakarta.apache.org
build tool) require JAVA_HOME although it's not Officially required by
Java itself.

FYI, there's also J2ME.  ;)

The three flavours of Java:

* J2SE - The basis of all things Java.  If you're trying to write or run
   desktop applications or applets, this is the flavour for you.
* J2EE - Think of it as the enterprise extension of regular Java,
   because it cannot exists on its own and requires J2SE installed.
   You'll need it if you're writing/running Servlets, EJB or JSP.  If you
   have no idea what these are, then you don't need it. =)
* J2ME - This is more like a stripped down version of J2SE, intended for
   mobile devices and devices with small computing power and resources.
   Again, if you don't know, then you don't need it. =)

Since you're not doing anything in the enterprise level or for mobile, 
J2SE is the flavour you're looking for.

Now the flavour part is settled, you're left with two choices: the J2SE 
runtime (aka JRE) or J2SE SDK (aka J2SDK).

* JRE - contains all the required components for *running* J2SE
   programs.  Most desktop systems already have one version of JRE or
   another installed, because it is required to view those annoying
   animated Java applet banners in your browser. =)  JRE, however, does
   not come with any tools for authoring Java programs.
* J2SDK - contains all things included in JRE, plus the applications
   required to compile Java source into bytecode (i.e., the runnable
   Java programs).

Now since you're trying to do some Java programming, you should get the 
J2SDK.

You may also want to try a Java IDE.  Currently there are three free 
Java IDEs that are worth trying:

* Borland JBuilder Personal Edition is a free (beer) IDE.  It does not
   contain any J2EE support, but that's not your concern now so it's OK.
   I particularly like the drag and drop GUI builder.  You can download
   it from Borland (http://www.borland.com/).
* Eclipse is an IBM-backed open source IDE.  It is supposed to be the
   successor for VisualAge.  It's more resource-intensive than JBuilder,
   but more flexible and supports more (programming) languages through
   the use of plug-ins.  The built-in CVS support is particularly useful.
   Get it at http://www.eclipse.org/
* NetBeans is a Sun-backed open source IDE.  The basis of Sun ONE
   Studio.  I tried it quite some time ago and I remember choosing
   Eclipse over NetBeans, but the reasons have already been forgotten. ;)
   It's available at http://www.netbeans.org/

Can anyone clarify for me just how the user's
data is collected by the program when using
the ncurses forms library?
I've got the Ncurses Programming HOWTO by
Pradeep Padala. It's full of good information,
but I can't figure out exactly how to gather
the information the user supplies to the form
so I can verify it and store it in a linked-list.
  Can anyone give me example code or
point me to a souce for example code which
uses the ncurses forms library to gather data,
process the data, and store it for further use?

One small correction here, you do not need J2EE to write servlets or JSP
(Java Server Pages) - J2SE contains all the required libraries for
(non-distributed) web applications.  You do need J2EE for EJB
(Enterprise Java Beans).  But as Cindy truly points out, if you don't
know what EJB is (are), you don't need them OR J2EE.

SDK: software development kit.

EE: enterprise edition (Which always make me wonder what sort of
enterprise - and if its number is NCC1701)

SE: standard edition.


The only difference I've seen between SE and EE is that EE has some
libraries that SE doesn't.
Therefore, if you need a sockets library and SE doesn't have it, look in
the EE library docs. If EE has it and you need it, you need EE. If not,
SE will do.

A pivot (note spelling, my fault, I spelled it wrongly in the first place)
table is the result of comparing some property of a pair of columns of data.
For example, you have a lecture timetable in a list thus:

Subject		Day	Time	Room
Math		Monday	0900	12
DBMS		Monday	1000	7
Hardware	Monday	1100	13
DBMS		Tuesday	1300	7
Comms		Tuesday	1500	Lab1
Lab		Thurs	1300	Lab2
Lab		Thurs	1400	Lab2
Lab		Thurs	1500	Lab2
Math		Friday	1200	3

Hardware	Monday	1000	7

not so easy to check as you dash down the corridor.  If you create a pivot
table of Subject on Day and Time, you get:

	0900	1000	1100	1200	1300	1400	1500
Mon	Math	DBMS	Hardware
Tue					DBMS		COMMS
Wed
Thu					Lab	Lab	Lab
Fri				Math

And a pivot table of frequency of time and room gets you:

Monday	0900	1000	1100	1200	1300	1400	1500
1
2
3				
7		2
12	1
13	1
Lab1
Lab2

Which shows you that you have accidentally scheduled two different classes
to use room 7 at 1000 on Monday.

So, in your case, you have a list of student ID, day and count of attendance
thus:

Student		Day	In
801		Mon	2
801		Tue	1
801		Wed	2
801		Thu	2
822		Mon	2
822		Wed	2
822		Thu	2
822		Fri	2
:
:
:

A pivot table of attendance on Student, Day gives you:

	Mon	Tue	Wed	Thu	Fri
801	2	1	2	2
822	2		2	2	2
837	2	2	2	2	2
923	1	1	1	2	2

Now you see that student 801 skipped one Tuesday and has no classes on
Friday, 822 has nothing on a Tuesday, 837 missed nothing while 923 was out
sick for 3 days running.

Apologies for the delay in replying...

You can use field_buffer to pull the data out of the field:

        buff =  field_buffer(field[0], 0);
        assert(buff != 0);
        printf("value: %s\n", buff);

where field[0] was assigned to earlier as:
        field[0] = new_field(1, 10, 4, 18, 0, 0);

You are correct that you don't _need_ J2EE for servlets and JSPs, but they
aren't included in J2SE, which is only the core Java classes.  To use them
you need to download an extra implementation of those functionalities, which
are included in J2EE or could be used from a web server/application server
implementing those APIs, for example Tomcat (http://jakarta.apache.org/tomcat),
 Resin, Weblogic, etc.

Becky

Hi Ed,

   Oops. Assert is separate from ncurses and is in assert.h:

#include <assert.h>
#include <stdio.h>

int main(int argc, char * argv[]) {
  assert(0);
}

for example results in:

test: test.c:6: main: Assertion `0' failed.
Aborted

It is used to assert that a condition is true or else the program
errors with an informative message. It is often used when debugging:

ASSERT(3)           Linux Programmer's Manual           ASSERT(3)

NAME
       assert - Abort the program if assertion is false.

SYNOPSIS
       #include <assert.h>

       void assert (int expression);

DESCRIPTION
       assert()  prints  an  error message to standard output and
       terminates the program by calling abort() if expression is
       false  (i.e.,  compares equal to zero).  This only happens
       when the macro NDEBUG was undefined  when  <assert.h>  was
       last included.

RETURN VALUE
       No value is returned.

CONFORMING TO
       ISO9899  (ANSI  C).   In  the 1990 standard, expression is
       required to be of type int and undefined behavior  results
       if  it  is  not,  but in the 1999 standard it may have any
       scalar type.

BUGS
       assert() is implemented as  a  macro;  if  the  expression
       tested  has side - effects, program behaviour will be dif­
       ferent depending on whether NDEBUG is  defined.  This  may
       create  Heisenbugs  which go away when debugging is turned
       on.

SEE ALSO
       exit(3), abort(3)

GNU                         1993-04-04                  ASSERT(3)

So, if you compile the above test program (test.c) as:

  gcc -o test-with-assert test.c

you'll receive the above error message. OTOH if you compile it as:

  gcc -o test-without-assert -DNDEBUG test.c

you won't receive an error message of any kind. In the example of
using ncurses forms, I was using it to insure that the return value
was not null and assumed you were familiar with assert's usage. My
apologies.

   As to a book on ncurses, there is a book on curses by O'Reilly:

          http://www.oreilly.com/catalog/curses/

and in fact I had a copy at one time but I probably gave it to the
library or sold it at half-price books some time back. ncurses is an
extension of curses and as far as I know ncurses implements all of
curses.

   Half.com has one for $3.75:

         http://half.ebay.com/cat/buy/prod.cgi?cpid=1534135&meta_id=1

Elizabeth
