== Credentials ==
When running commands that require a connection to a remote machine its useful to be able to store a user/pass combination so that you aren't repeatedly prompted every time you run a command.  Create a credential object, then supply that in place of a username in a command
 
<pre>
PS H:\> $cred = Get-Credential
 
cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Credential
PS H:\> Get-WMIObject -query "SELECT * FROM Win32_OperatingSystem" -credential $cred -computer 159.104.224.167

== WMI ==
 
Cmdlet for using WMI via PowerShell is '''Get-WMIObject''', which has an alias of '''gwmi''', for example...

PS H:\> Get-WMIObject -query "Select * from Win32_userAccount WHERE Domain = 'OCM-WCS1' AND Name = 'pptp_ypos'" -credential administrator -computer 159.104.224.167

</pre>
 
 
=== Find Classes and Properties ===
 
In order to find the correct class use...
<pre>
Get-WMIObject -list -credential $cred -computer 159.104.224.167 | Select-String -InputObject {$_.Name} Win32*
</pre>
 
To then see all the properties of a class use (doesn't work on remote machines (access denied) - this is a known bug in Power Shell v1)...
<pre>
Get-WMIObject Win32_BIOS | Format-List *
</pre>

== Network ==
=== Ping ===
<pre>
PS H:\> $objPing = New-Object system.Net.NetworkInformation.Ping
PS H:\> $objPing.Send('127.0.0.1')
 
Status        : Success
Address      : 127.0.0.1
RoundtripTime : 0
Options      : System.Net.NetworkInformation.PingOptions
Buffer        : {97, 98, 99, 100...}
</pre>
 
=== Name/Address Resolution ===
'''IP to Name'''
* Be aware, where no name can be found, the call throws an exception.  If assigning result to a variable, then it seems to return the local hostname, which is odd.
<pre>
PS H:\> [System.Net.Dns]::GetHostbyAddress("159.104.31.83")
 
HostName                                Aliases                                AddressList
--------                                -------                                -----------
L-STRUTTS1                              {}                                      {159.104.31.83}
</pre>
 
'''Name to IP'''
<pre>
PS H:\> [System.Net.Dns]::GetHostAddresses("l-strutts1")
 
Address          : 1394567327
AddressFamily    : InterNetwork
ScopeId          :
IsIPv6Multicast  : False
IsIPv6LinkLocal  : False
IsIPv6SiteLocal  : False
IPAddressToString : 159.104.31.83
</pre>
 
== MySQL ==
<pre>
function ConnectMySQL([string]$user,[string]$pass,[string]$MySQLHost,[string]$database) {
 
  # Load MySQL .NET Connector Objects
  [void][system.reflection.Assembly]::LoadWithPartialName("MySql.Data")
 
  # Open Connection
  $connStr = "server=" + $MySQLHost + ";port=3306;uid=" + $user + ";pwd=" + $pass + ";database="+$database+";Pooling=FALSE"
  $conn = New-Object MySql.Data.MySqlClient.MySqlConnection($connStr)
  $conn.Open()
  $cmd = New-Object MySql.Data.MySqlClient.MySqlCommand("USE $database", $conn)
  return $conn
}
 
function WriteMySQLQuery($conn, [string]$query) {
  $command = $conn.CreateCommand()
  $command.CommandText = $query
  $RowsInserted = $command.ExecuteNonQuery()
  $command.Dispose()
  if ($RowsInserted) {
    return $RowInserted
  } else {
    return $false
  }
}
 
# setup vars
$user = 'myuser'
$pass = 'mypass'
$database = 'mydatabase'
$MySQLHost = 'database.server.com'
 
# Connect to MySQL Database
$conn = ConnectMySQL $user $pass $MySQLHost $database
 
# Read all the records from table
$query = 'INSERT INTO test (id,name,age) VALUES ("1","Joe","33")'
$Rows = WriteMySQLQuery $conn $query
Write-Host $Rows " inserted into database"
