I have a list of servernames
PARDC1 EURDC2 EURDC3 USADC1 USADC22 CHNDC1 CHNDC2
I have created a hashtable to pick the first 3 letters of servernames, and classify it in a region.
PAR = EMEA
EUR = EMEA
USA = NAM
CHN = APAC
I want to use the lookup table to classify all servers in appropriate regions.
How do I go about doing this in Powershell ?


You can create an empty hash table with
$hash = #{}
You can then add entries to it with
$hash['foo'] = $bar
or
$hash.foo = $bar
and access them the same way later again.

Hi, I am creating a GUI which contains DropDowns. They are 10 dropdowns as you can see from the code. And I am using assignin to save each one of them into base workspace. But I would like to club all of them into a 2 char array's or 2 cell array's and send only two variables into the base workspace viz, Roll_nos and Projnames_GUI

Create two cell arrays and assign them in the base workspace:
roll_nos = {
app.StudentInfoDropDown.Value,
app.StudentInfoDropDown_2.Value,
app.StudentInfoDropDown_3.Value,
app.StudentInfoDropDown_4.Value,
app.StudentInfoDropDown_5.Value
};
projnames_gui = {
app.ProjectInfoDropDown.Value,
app.ProjectInfoDropDown_2.Value,
app.ProjectInfoDropDown_3.Value,
app.ProjectInfoDropDown_4.Value,
app.ProjectInfoDropDown_5.Value
};
assignin('base','Roll_nos',roll_nos)
assignin('base','Projnames_GUI',projnames_gui)

I am using Mojolicious Perl framework in my application. I want to store an array in session, but is not successful.
my #returnResult;
$returnResult['fn'] = $decoded->{'fn'};
$returnResult['ln'] = $decoded->{'ln'};
$self->session(returnResult => #returnResult);
Please help.

See hashes in Modern Perl and perldata.
my %return_result;
$returnResult{fn} = $decoded->{fn};
$returnResult{ln} = $decoded->{ln};
or
my %return_result = (
fn => $decoded->{fn},
ln => $decoded->{ln},
);
or simply
# http://perldoc.perl.org/perl5200delta.html#New-slice-syntax
my %return_result = %$decoded{qw(fn ln)};
You do not get automatic references like in other languages. Use the \ operator.
$self->session(returnResult => \%return_result);

I want remove common element from array. For example:
array1 =
[
{'id'=>78597,'data'=>'great'}
];
array2=
[
{'id'=>78345,'data'=>'first'},{'id'=>78597,'data'=>'great'},
{'id'=>78355,'data'=>'second'}
]
Now key Id '78597' is common in both array
Now i to want remove that element from array2 based on the key 'id'. The examples I referred where all single dimension.

You can build %seen hash lookup and filter #$array2,
my %seen;
#seen{ map $_->{id}, #$array1 } = ();
#$array2 = grep { !exists $seen{$_->{id}} } #$array2;

I have this data of year, month, date. I want this to show as year,month,date in Matlab and don't know how to do.

The simplest way would be to reshape the matrix and use it accordingly. I demonstrate the way to reshape and print all the dates in US (MM/DD/YYYY) format.

X_in_better_format = reshape(X,3,42)';
for it = 1:size(X_in_better_format,1)
sprintf('The date is %d/%d/%d',X_in_better_format(it,2),X_in_better_format(it,3),X_in_better_format(it,1)) %US Format
