Hello Jonathan,
Well to start I would suggest you should use a hash if your
$id's are unique. If they aren't then you will have to live with
arrays. To create a hash this is what I would do
## --- Perl Code Below --- UNTESTED code
my %data; ## A Global declaration
open FILE, "your-file.txt"; ## Insert your comma delimited file here
foreach (FILE) { ## Fill read file up til a 'newline'
my @temp = split/,/, $_; ## Split the string
s/^\d{3},//; ## This removes the first 3 digits and
## a comma from $_
$data{$temp[0]} = $_;## Assign a key a value to your hash
}
## This loop simply prints each key and its value to confirm that
## everything has worked.
foreach (keys %data) {
print "Key:$_ Value: $data{$_}\n";
}
## --- END OF PERL CODE
After the above code is finished you will have a Hash called %data
that contains all data with keys that are created with your ID's. The
next part... actually sorting you can use the code I sent you before.
I am a little confused about one thing though. My code simply sorts
alphabetically or from highest to lowest. From your email I don't
think that's what you are trying to do. However all you ahve to do is
create another hash from %data and then edit the values until they
suit your sorting requirments. For example to sort for only names
that start with 'M' you could do the following:
## --- Perl Code Below --- UNTESTED code
my %sorthash = SortSub('M',%data);
##---
sub SortSub {
my $letter,%sorthash = @_;
foreach (keys %sorhash) {
my @data = split/,/, $_;
## If it doesn't start with a 'M' then put whatever is needed
## to put it at the end of your sort routine.
$sorthash{$_} = "zzz" if ($data[0] !~ /^$letter/);
}
}
## END OF PERL CODE
Now you can use the 2 hashes (%data,%sorthash) and use the code I sent
you that sorts alphabetically. Everything that doesn't start with 'M'
with be sent to the end. Let me know if this helps. I don't have a
lot of time these days, but if you are still stuck send me the code
and we'll see if can hack something togther. Cheers

JS Cam,
JS Thanks for the help. I am trying to get the sort part to work. Seems pretty
simple as you stated ... I just need to
JS figure out HOW to apply it to my program.
JS My data is stored in a comma delimited file. Here is the format: (with sample
data)
JS 857,Gabe,Skrinjar,Ravine,109-1,00:60:67:25:91:92,141.195.134.100
JS 858,Kelly,Murphy,Schultz,313-2,00:60:67:25:91:9b,141.195.134.101
JS 860,Tara,Dodge,Walker,260-1,00:50:da:c8:ff:7b,141.195.134.102
JS 861,Fabrizio,Polo,Baldwin,A312-1,00:01:02:28:9f:e6,141.195.134.103
JS I read in the data:
JS ($id,$fname,$lname,$build,$room,$adap,$ip) = split(/,/)
JS and ignore the $id.
JS A specifc search is done on all the data based on the "subject" of a tab-click on
a TabView object. I have three tabs:
JS Name, Building, and Adapter Address. For instance: someone wants to get a list of
all the people whose First and last
JS names begin with 'M'. These are displayed in the ListView window.
JS The data that is displayed needs to be sorted if the user clicks on a tab.
JS I guerss I don't know how to store the data in a hash to be used with your code.
Any ideas? I can supply the code if
JS you want.
