That understanding will help you, but there will be other differences. For instance, this.that = 2 in VB would be $this->{that} = 2 in Perl. But something like a method call would be this->DoSomething.

Using Win32::OLE isn't as straightforward as you might want it to be. The biggest things to look out for is that when you're setting properties, you're going to be using a hash, and there are other times when you're going to be using lists. For example..

This is some DB code that uses ADO..

#!/usr/bin/perl -w

use strict;
use Win32::OLE;

my $strCon = "Provider=SQLOLEDB; Data Source=XXXXX; Initial Catalog=SM
+S; "
    . "User ID=XXXXX; Password=XXXXX";
    
my $strSql = "SELECT System_DATA.Name0, datediff(dd, LastUpdateDate, g
+etdate())" 
    . " 'age' FROM SoftwareInventoryStatus INNER JOIN System_DATA on "
     . "System_Data.MachineID = SoftwareInventoryStatus.ClientID WHERE
+ "
     . "(datediff(dd, LastUpdateDate, getdate()) > 30)" ;
    
my $objCon = new Win32::OLE("ADODB.Connection");
my $objRecordset = new Win32::OLE("ADODB.Recordset");

$objCon->{'ConnectionString'} = $strCon;
$objCon->Open;

$objRecordset->Open($strSql, $objCon);

while (not $objRecordset->{'EOF'}) {
    print $objRecordset->{'Name0'}{'Value'}, "\t";
    print $objRecordset->{'age'}{'Value'}, "\n";
    $objRecordset->MoveNext;
}

$objRecordset->Close;
$objCon->Close;

and someting similar in VB (sorry, this below is from some ASP a customer asked me to put together. Above is something I use. They don't perform the same task, but you should be able to see what mirrors what.

Option Explicit
Dim objConnection, objRecordset, strSQL, Name

Set objConnection = Server.CreateObject("ADODB.Connection")
objConnection.ConnectionString  = "Provider=SQLOLEDB; Data Source=XXXX
+; Initial Catalog=SMS; User ID=XXXX; Password=XXXX"
objConnection.Open

Set objRecordset = Server.CreateObject("ADODB.Recordset")
strSQL = "SELECT Name0, MachineID FROM System_DATA WHERE  MachineID >=
+ 0 ORDER BY Name0"
objRecordset.Open strSQL, objConnection
[download]

and what was a little confusing to figure out is that in VB, You can refrence the "Name0" field as objRecordset("Name0") but in Perl it's $objRecordset->{'Name0'}{'Value'} I personally prefer Perl, but with things like Win32::OLE it's a lot of poke and hope to figure out just how you have to access properties and methods.
