I'm writing a script that sends messages via the serial port at the moment. I'm really quite hopeless at Perl so I need a little help. Perl is great at handling strings but I'm having trouble finding accurate info on how to specify a 4 bit hex value. I've basically gotta send two 4bit chunks of data and a whole host of 8 bit chunks. ...

The following will stop to open test.pl due to using param('userid') and param('pwd'). Is there an alternative way to get data from HTML file to CGI file? I have to do this in the particular situation. -------- html file --------- <form name = "form3" action = "http://localhost/scripts/test.pl" method = post> Name: <INPUT TYPE = text NAME =...

How do I make .cgi extention work? I installed ActivePerl 5.8. My CGI scripts work fine with .PL extention but not .CGI extention although I associated CGI extention as exactly same as PL extention in WinXP Prof . Where else should I change to make it work?

Greetings, My problem is I need to call a subroutine but the number of args can be many and vary from call to call. What I'm trying to do is parse a template and capture the data from the template into a scalar and then call the subroutine with the scalar value and have perl substitute the scalar with the data in the scalar and have that...

I have a large list of DB_Files stored in a directory. I would like to tie all of them to an array of hashes and to search them for key, using the hashes. My idea is rather simple: my (@listOfHashes); my ($numOfHashes); sub loadDBs{

I know regex can't do this, so may I ask what the recommended procedure is for extracting a bracketed TeX argument, which itself can contain other bracketed TeX arguments? $string = " text \sometexmacro{arg1}{this is a second {\bf arg} argument} more text"; and file.pm has a sub that makes it easy to describe all the arguments to...

First off I'll say - I am a bad perl programmer. I want to be better and with your help I'll get there and then be able to contribute more here. That being said, I have a simple problem compounded by file size. I have a PIX that logs to my syslog server for a ton of items - my logs sizes get extremely large; ~13 GIGABYTEs daily and they...

Does anyone know how to monitor the existance of a process running in windows task manager. Basically I want to start another process only if the previous has finished and the script runs in windows. Thanks

Hi, I'm wondering if object-oriented perl is a must-use if say you're going to code a pretty large program. I've used perl for almost a year but have written large plain perl code. I try to organise my code by putting related subs in different modules and have the main script call those subs. In that way, I'm able to reuse some of the...

Hi, Im looking for a script that checks the status of some remote servers (ftp/web and userdefined port), and update the status in an html file. I used to have a working php script but since that did all the connects 'live' from the html it got shutdown because of generating exessive load. Is there a perlscript that can do this ?

Hello, there's something I'd like to understand... I want to connect to the MS SQL Server database, get some records, store them into the text file, send the file through VPN connection and then send the email message about the task success or failure. First steps are quite easy but using the VPN connection makes me feel powerless......

I'm trying to install the Device::SerialPort module using CPAN but whilst CPAN is running 'make test' a couple of errors are flagging so I cannot continue the install without forcing it. I'm not too worried about the errors as the success rate is still around 99.7 percent. Anyway, so how do I force the install?? I tried -f and --force...

Hello, I have a csv with name, address, city, state, zip (XXXXX-XXXX). I am hoping to group all the similiar zip codes and produce a count on each group. My match so far is m/^\d{5}-\d{4}$/ A match by the first five is ok, but how would I roll through each one? (for example 90210, 90211, 90213 ...) thanks JS

When running the sample code below without a proxy the GET returns the expected data. When run with the $proxy uncommented the GET returns the content of the login page for the site being accessed. The site in the code is valid for ease of testing. I also am including the LWP debug info for each attempt. Can anyone explain this behavior...

Hello group, I'm interested in starting to learn Perl and CGI. I'm not having any problems with that. However, setting everything up is not clear to me. What should I do to run my CGI scripts on my computer, with my browser. I need to be able to run these CGI scripts on my own browser, so I can test what I'm doing. I'm not interested in...

Hi folks, I'm using perl (actually, mod_perl environment on RH 8.0) to connect to an external SSL server. I feed it an XML request and get a response back. The problem is, the server is flaky, and I'd like to be able to timeout / break if I haven't gotten a response in X seconds. (Note that the server may connect, but simply not send a...

Hello All, I'm trying to parse through a webpage, and I used HTML::treebuilder to try to get it into an easily managable data structure. I am having a bit of trouble parsing through it though. Here is a snippet of code: $tree = HTML::TreeBuilder->new; $tree->parse($response->content);

I am learning Perl and was using the Wrox Learning Perl book that I found on the web. The author was explaining the autoincrement operator and try as I might I can't understand this behaviour. The line of code read... $a = "9z"; print ++$a, "\n"; Aparently Perl reads in the ranges a-z, A-Z, 0-9 and if it caps off a range then it will add...
