Bottom of the page. I list two different ways:
Range Example:
my $sheetcnt = $Book->Worksheets->Count();
foreach (1..$sheetcnt)
{
print "\t" .$Book->Worksheets($_)->{Name} ."\n";
}
'IN' Example
foreach my $Sheet(in $Book->{Worksheets})
{
print "\t" .$Sheet->{Name} ."\n";
}
I suggest reading the entire tutorial.

Assuming you have outlook, this should get you started:
use strict;
use Win32::OLE qw(in with);
use Win32::OLE::Const 'Microsoft Outlook';
$Win32::OLE::Warn = 2; # Throw Errors, I'll catch them
my $outfile = 'c:\perl\projects\improvdb\nahatemailssorted.txt';
my $OL = Win32::OLE->GetActiveObject('Outlook.Application') or die
Win32::OLE->LastError();
my $NameSpace = $OL->GetNameSpace("MAPI");
my $Folder = $NameSpace->GetDefaultFolder(olFolderInbox);
foreach my $msg (in $Folder->{Items}){
if ($msg->{Subject} =~ m//i)
{
#Here, there be move code
}
}
Also, I wrote a tutorial on using Excel and Win32::OLE on perlmonks, but the
beginning portion is applicable to all Win32::OLE use, and is worth the
read.
http://perlmonks.org/index.pl?node_id=153486
Otherwise, using Win32::MAPI would also be a choice.

No, actually, the point of those two code snippets is to get an 'Active
Object' of said type. That is, if there is already an instance running,
connect to it instead of instantiating a new OLE server.
To START a new OLE server, you would use:
my $Excel = Win32::OLE->new('Excel.Application', 'Quit');
I usually do something like this (to cover all bases):
my $Excel = Win32::OLE->GetActiveObject('Excel.Application')
|| Win32::OLE->new('Excel.Application', 'Quit');
Which says "If there is already an instance running, use it, otherwise,
start me a new one."
I hope that helps,

No worries. I didn't take any offense, just offering a little more info to
the mix regarding using Cell and Range. If the user could only use ints,
then Cell is the only way he could go. Personally, I would have just
converted to letters and used a multiple entry range
$Sheet->Range("a1:c3, r5, c5:t3")->
but be that as it may.
I have pretty thick skin and will usually throw the bozo bit before I get
too rankled anyway.

RE: dynamic reports

All of the above an accomplish what you are looking for. Crystal offers you controls that dynamically create your queries offering you a "smoother" interface (I never really liked crystal because of some scaling issues) but in most cases, you are going to have to include those controls in code (take your pick of languages). Perl (or any pure language approach) is more of a brute force approach, meaning that you are going to have to handle all of the db connections, rendering techniques, data sets, etc. XML is nice, as you could retrieve a large amount of data to a data island and work XSL against it as the queries change. Honestly, for most small and medium applications, if you were to go with a code approach (Perl, C, .NET, whatever) I would say use a combination of Data sets and XML/XSLT. For applications of any real size, however, you might want to start looking at an off the shelf package. We use Actuate (but there are others out there), and have had pretty decent ROI given the number of reports we run (1000s a day), etc. Chuck Charbeneau Lear Corporation Lead Software Applications Engineer ccharbeneau at lear dot com ** ** LEGAL DISCLAIMER ** ** This E-mail message and any attachments may contain legally privileged, confidential or proprietary information.

What have you tried so far? I usually suggest that if you're new to using excel, read this: http://perlmonks.org/index.pl?node_id=153486 What you could do is open one instance of Excel, open both files as separate objects, activate the CSV file, Select your given range, activate the Excel file, find the last row and column, and then paste the Applications current selection starting at the range of the last row and column. This will work if the data areas are the same shape. If you have to iterate through the CSV data and put it in different rows and columns, just open the CSV file as a txt file directly in perl, iterate through the file and insert the data one cell or row (line of CSV data) at a time into the excel file, saving when you are complete.

If this is working as web script on IIS (I can't speak for others), then the
cwd will end up being the WEB SERVERS working directory. I would suggest
including some code to apply the users environment info to the script,

I would say that it IS seing it as a variant type
Try forcing the type like so:
use strict;
use Win32::OLE qw(in with);
use Win32::OLE::Const 'Microsoft Excel';
use Win32::OLE::Variant;
use Win32::OLE::NLS qw(:LOCALE :DATE :TIME);
my $Excel = Win32::OLE->GetActiveObject('Excel.Application');
$Excel->{DisplayAlerts}=0;
my $Book = $Excel->{ActiveWorkbook};
my $Sheet = $Book->Worksheets("Sheet1");
$Sheet->Activate();
my $dt = Variant(VT_DATE, $Sheet->Range("a2")->{Value});
## A2 has your decimal value, You can also input a time value,
## (10:22:54 pm) and it will work
print $dt->Time, "\n";
print $dt->Time(TIME_FORCE24HOURFORMAT|TIME_NOTIMEMARKER), "\n";
print $dt->Time("hh.mm.ss tt"), "\n";
The following is directly from the ::Variant docs
.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=.-=
Converts the VARIANT into a formatted time string. FORMAT can be either
one of the following integer constants or a format string:
LOCALE_NOUSEROVERRIDE system default time format for this locale
TIME_NOMINUTESORSECONDS don't use minutes or seconds
TIME_NOSECONDS don't use seconds
TIME_NOTIMEMARKER don't use a time marker
TIME_FORCE24HOURFORMAT always use a 24-hour time format
The constants are available from the Win32::OLE::NLS module:
use Win32::OLE::NLS qw(:LOCALE :TIME);
The following elements can be used to construct a time format string.
Characters must be specified exactly as given below (e.g. "dd" B "DD").
Spaces can be inserted anywhere between formating codes, other verbatim

RE: Distance between 2 latitudes and longitudes
This time, I'll post it to the list:

I must have missed the original post. There are actually a couple of
different methods for determining the distance between 2 long/lat pairs and
you need to be aware of the accuracy of each. The Great Circle method is the
least accurate IIRC, but is the most accessible, as it is a part of
Math::Trig.
I wrote some code to do this using the various methods. Actually, it finds
the distances between two zip codes for which the long/lat pairs are known,
but I'll remove the database stuff for you and just give the pertinent code.
You should also read:

and my favorite:
http://op.gfz-potsdam.de/GMT-Help/Archive/msg00143.html
use Math::Trig qw(deg2rad pi great_circle_distance asin acos);
my ($lat1, $long1);
my ($lat2, $long2);
print "Haversine : ". &Haversine($lat1, $long1, $lat2, $long2) ."\n";
print "Law Cosines : ". &LawCosines($lat1, $long1, $lat2, $long2)."\n";
print "Flat-Earth : ". &FlatEarth($lat1, $long1, $lat2, $long2) ."\n";
print "Great Circle: ". &GreatCircle($lat1, $long1, $lat2, $long2)."\n";
sub LawCosines {
my ($lat1, $long1, $lat2, $long2) = @_;
my $r=3956;
my $dist = acos(sin(deg2rad($lat1))*
sin(deg2rad($lat2))+
cos(deg2rad($lat1))*
cos(deg2rad($lat2))*
cos(deg2rad($long2)- deg2rad($long1))) * $r;
return $dist;
}
sub FlatEarth {
my ($lat1, $long1, $lat2, $long2) = @_;
my $r=3956;
my $a = (pi/2)- deg2rad($lat1);
my $b = (pi/2)- deg2rad($lat2);
my $c = sqrt($a**2 + $b**2 - 2 * $a *$b
*cos(deg2rad($long2)-deg2rad($long1)));
my $dist = $c * $r;
return $dist;
}
sub Haversine {
my ($lat1, $long1, $lat2, $long2) = @_;
my $r=3956;
$dlong = deg2rad($long1) - deg2rad($long2);
$dlat = deg2rad($lat1) - deg2rad($lat2);
$a = sin($dlat/2)**2 +cos(deg2rad($lat1))
* cos(deg2rad($lat2))
* sin($dlong/2)**2;
$c = 2 * (asin(sqrt($a)));
$dist = $r * $c;
return $dist;
}
sub GreatCircle {
my ($lat1, $long1, $lat2, $long2) = @_;
my $r=3956;
my @zip1 = (deg2rad($long1), deg2rad(90-$lat1));
my @zip2 = (deg2rad($long2), deg2rad(90-$lat2));
my $dist = great_circle_distance(@zip1, @zip2,$r);
return $dist;
}
Hope that helps.
Chuck.

Their sizes are the same. As a matter of fact, I wrote exactly that for the ME department at Michigan Tech. But what have you tried already? Many of us here would hardly want to do either your job or your homework for you without first seeing what you have already tried.
