Encoding text
Hi,
I want to encode a string using the translate function.
decoding is well documented by
$value =~ tr/+/ /;
$value = s/%([a-fA-F0-9][a-fA-F0-9])/pack("C",hex($1))/eg;
what i would like to do is to use the translate command to replace just the
special chars into hex encoding %??
My quess was to try and convert all chars that are not normal chars but I
am not sure how to do this.
Your suggestions will be appreciated.
Best regards
Mike

RE: text/area editing
Hi, my cgi compiles on the command line, but I get an internal server error
when
I try to access in the browser
use strict;
use warnings;
my $file_name='';
my $content='';
$file_name = 'testfile';
open TEXT, $file_name or die "couldn't open '$file_name' for reading: $!\n";
while () {
$content .= $_;
}
print<
http://www.ramonred.net/cgi-bin/text.cgi";>
$content
EOF
# end of text.cgi
I have made sure the permissions are set correctly.
Any ideas what could be wrong?

It's a good question, but I think you better should ask it in a database newsgroup. The only answer I can give you in the sort is, it depends (on your specific problem, we don't know).

Unless you work really hard at it, your image is always scaled in proportion, such that the width and the height fit a maximum of the sizes listed above. It's just (dare I say) magic! Let me illusrate: if an image is 75x150, and you ask for a 25x25 version, you get a 12x25 version, which is the same proportions, but both numbers are smaller than 25. -- Randal L.

The data is encrypted with the server certificate, and you should be able to look at what certs you have with your browser. >The spiel I have just read talks about a 'digest' but all that >is doing is verifying that the information you sent to the user is >coming back unaltered. > >Why send data to a user for them to send back to you? How do I mangle a >credit card number and decode at my end??? You don't need to if using https. If you are not using https, you should not be taking credit cards. However, once the cc number gets into your server, you should encrypt it before writing it to disk, so others on the system, can't accidently read them. The reason people send data to users, just to send it back, and have it verified, is to prevent the "user" from playing tricks. What is someone make an order for 1 widget, at an agreed upon price, you send the page for user verification, and they edit the page to a lower price, and send it back. You need to keep track of what is what. There are other ways of doing this, but they involve writing to disk files to "save the state" of the transaction. The above method saves you the trouble of writing to disk, until the transaction is finalized. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
text/area editing
Hi, I would like to create a form that loads text into a text/area box for editing. So far in the books that I have I only see how you can post that is added to the text/area only. In my case I would like the html or cgi page to load with the text/area box already containing text. Is there a good book that someone could recommend that would cover this? Or? thanks. ramon hildreth www.ramonred.net -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
