I experimented with commenting out each line on its own:

#header
#
#help

or using comment blocks

<#
header
help
#>

even

<#
header
#>
<#
help
#>

and a couple more variations, but no joy. After some “binging” I ended up reading about_Comment_Based_Help;

All of the lines in a comment-based Help topic must be contiguous. If a comment-based Help topic follows a comment that is not part of the Help topic, there must be at least one blank line between the last non-Help comment line and the beginning of the comment-based Help.

It still took some more trial and error to realize that an “empty line” well, needs to be really empty. It cannot contain a comment character either! Call me stupid ;-)

Here’s an example of how it should be done (Ref. line 22):

#.SYNOPSIS
#Create custom address lists
#
#.DESCRIPTION
#Create custom address lists based on a CSV file called "CreateAddressLists.csv" with these columns
# - Name
# - Container
# - RecipientFilter
#The script will check if the "Container"-field is empty and run de cmdlet with or without "-container" option
#
#.Link

$Input = "CreateAddressLists.csv"
Import-CSV $Input | Foreach { If ($_.Container -eq "") {New-AddressList -Name $_.Name -RecipientFilter $_.RecipientFilter} else {New-AddressList -Name $_.Name -Container $_.Container -RecipientFilter $_.RecipientFilter}}

For those of you wondering, I have the habit of using scripts not just for bulky or repetitive actions but also as means of documentation and standardization. Additionally these scripts come in handy If you ever need to rebuild some part of the infrastructure. Hence the 35 lines of comment for only 2 lines of code.

So I created PowerCLI Language definition file for syntax highlighting. It contains the cmdlets available in vSphere PowerCLI 4 Update 1 and vCenter Update Manager PowerCLI 4 Update 1.

To add PowerCLI as a user-defined language %APPDATA%\Notepad++\userDefineLang.xml and add the above configuration to this file.

Secondly I created a PowerCLI auto-completion file which contains the same PowerCLI cmdlets. This configuration needs to be added to C:\Program Files\Notepad++\plugins\APIs\PowerCLI.xml. The name of the auto-completion file needs to be the same as defined in the user-defined language definition file.

$Cluster = Get-Cluster -Name (Read-Host "Please enter the name of the cluster whose servers need to be reconfigured.")
$vSwitch = Read-Host "Please enter the name of the vSwitch on which the portgroups need to be created."
$PGfile = import-csv -Path (Read-Host "Please enter the path to the csv file with the new portgroups to be added to the vSwitch")

}
}

Disconnect-VIserver -Server $vCenter -Confirm:$False

The script asks for

• vCenter IP or FQDN
• Cluster Name
• vSwitch name
• Path to the csv file

The csv file contains the portgroup names and vlanid’s.

PortGroupName,Vlanid
VLAN900,900
VLAN901,901
VLAN902,902

import-csv ‘SecurityGroups.csv’ | foreach {
New-QADGroup -Parent $_.ParentContainer -Name $_.Name -sAM $_.Name -GroupScope $_.GroupScope -GroupType $_.GroupType
}

This script imports a .csv file to create the security groups. The .csv file contains the OU distinguished name, the group Name, the group type (security or distribution) and finally the scope (Domain Local, Global or Universal).

It looks like this:

Parentcontainer,Name,Grouptype,GroupScope
“OU=Sharepoint,DC=domain,DC=local”,SecurityGroup01,Security,DomainLocal

• about_regular_expressions or about_regular_expression?
• $_. or $._?
• Why is -Confirm $False not working?

This time I decided to try and automate that demo by using the autoreplace feature (Hotstring) in AutoHotKey. The main goal is avoiding typo’s by using tried and true commands in a working order. A poor man’s Start-Demo script if you wish ;-)

The script starts of with a bunch of commands controlling the overall functionallity (the first 3 come with the default template):

#NoEnv

Recommended for performance and compatibility with future AutoHotkey releases.

SendMode Input

Recommended for new scripts due to its superior speed and reliability.

SetWorkingDir %A_ScriptDir%

Ensures a consistent starting directory.

#Hotstring EndChars `n

Limit the hotstring end characters to ENTER only

#Hotstring O

Don’t actually type the end character. (I want to launch the command myself after/during my explanation.)

#Hotstring R

Type replacement text in raw mode. (To prevent AHK from interpreting e.g. “{“)

The remainder of the script is actually a long list of hotstring definitions like these ones

::ems01::Get-Help
::ems02::Get-Help About
::ems03::Get-Help About_Regular_Expression
::ems04::Get-Command *mailbox
::ems05::Get-Help New-Mailbox
::ems06::Get-Help New-Mailbox -Detailed
::ems07::Get-Help New-Mailbox -Full

and so on.

Seems stupid with these simple examples, but the advantage becomes clear for more complex commands. Lets take “ems26″ for example;

::ems26::1..10 | Foreach-Object { new-mailbox -Database “Mailbox Database 2″ -Name (“User” + $_) -UserPrincipalName (“User” + $_ + “@exchange2007.lab”) -Password $Pwd }

When I type “ems26″+ENTER in EMS AutoHotKey executable automatically replaces this string with “1..10 | Foreach-Object { new-mailbox -Database “Mailbox Database 2″ -Name (“User” + $_) -UserPrincipalName (“User” + $_ + “@exchange2007.lab”) -Password $Pwd }” and waits. I do my talking and then hit ENTER again to execute the command.

It worked nicely actually. People were impressed with my typing skills ;-) I only encountered one error because I didn’t delete some manually after a test the day before. It even works with shell running inside a VM while the AutoHotKey script is running on my physical computer.

After some more research I discovered the SQLite ADO.net 2.0 Provider but I couldn’t get it to work immediately.

It took me a couple of days to find the blog post Database Queries with Windows Powershell. (This blog seems to have moved recently as most of the hyperlinks/search results are still referring to Typepad). The post is nicely commented, so I could rather easily translate the MySQL to SQLite statements with some assistance from the included help file.

[void][System.Reflection.Assembly]::LoadFrom("D:\DATA\Tools\System.Data.SQLite.dll")

$cn = New-Object -TypeName System.Data.SQLite.SQLiteConnection
$cn.ConnectionString = "Data Source=D:\DATA\Tools\koen.sqlite"
$cn.Open()

$cm = New-Object -TypeName System.Data.SQLite.SQLiteCommand
$sql = "SELECT FirstName, LastName FROM tblKoen"
$cm.Connection = $cn
$cm.CommandText = $sql
$dr = $cm.ExecuteReader()

while ($dr.Read())
{
    write-host $dr.GetString(0) " " $dr.GetString(1)
}

$cn.Close()

Some more interesting links I came across:

• Learn SQL
• SQLite ODBC driver
• SQLite Tutorial

1st prize: The guest provisioning system of LucD. This application lets you provision your VMs in an easy way. You can set the options from one screen no clicking around to configure everything manually.

2nd prize: VI Power Documenter by tzamora. This script generates reports about your virtual infrastructure.

3rd prize: PowerVDI script by Dan Baskette. It let you deploy multiple VDI instances on an EMC celera using snapshots and AD integration.

I’m sure there are other contributions that are very useful.

Congrats to the winners. Nice job guys.

This makes managing your VMware environment using  Powershell even more easier. PowerGUI lets you write your own Powershell scripts and the VMware PowerPack is also compatible with the VI client plugin. The plugin uses your current connection to the VC. You don’t need to make a separate connection for every script.

• They replaced get-viserver with connect-viserver. get-viserver is now an alias for connect-viserver.
• disconnect-viserver was added which allows you to do a clean disconnect. Hence the rename of the get-viserver cmdlet.
• VMware also added cmdlets for managing the VMware Update Manager.
