PowerShell – Multiple (-and) (-or) within a single If statement

I had a hard time finding examples on the web on how or if you could code multiple If’s into a single If statement, so I thought I would just quick post up an example once I figured out how to do it. Perhaps I wasn’t looking in the right places but all the examples I saw were just a single (-and) or (-or) in the code.

So based on being able to code an If statement in either of the following fashions:

If ($someAttribute -eq $false -or $someAttribute -eq $Null){

}

or the following:

If (($someAttribute -eq $false) -or ($someAttribute -eq $Null)){

}

Then we should be able to do a combined effort:

If (($someAttribute -eq $false -or $someAttribute -eq $Null) -and ($someUser -eq “UserID123”)){
       Write-Host “Switching to True”
       Set-QADUser $someUser -Service “MyDomain.org” -ObjectAttributes @{$someAttribute = $True}
       If (!$?) {Write-Host “Error: $($error[0])”}
}

So if $someAttribute is either $false or $Null AND #someUser equalsUserID123″ then do something… in this case I switch the Attribute someAttribute to $true and do some error checking.

PowerShell – ProperCase Function

Change any case to Proper Case (‘ITNOTES DoT net’ to ‘Itnotes Dot Net’):
This is very useful for us during scripted user creations when the usernames and such from the source were in random cases. This script could also be useful with auto user provisioning with ILM/FIM 2010 from another datasource, we were using a VBScript that is much longer.

This script basically converts everything to lowercase then capitalizes the first letter of each word.

function ToProperCase ([String]$in)
{
 $in = $in.Tolower()
 $textInfo = [System.Threading.Thread]::CurrentThread.CurrentCulture.TextInfo  
 return $textInfo.ToTitleCase($in)
}

Example of use:
$Title = “ITNOTE DOT NET”
ToProperCase($Title)

Returns:
Itnotes Dot Net

Complete Script

function ToProperCase ([String]$in){
 $in = $in.Tolower()
 $textInfo = [System.Threading.Thread]::CurrentThread.CurrentCulture.TextInfo
 return $textInfo.ToTitleCase($in)
}
$Title = “ITNOTE DOT NET”
ToProperCase($Title)

As noted by Lee, here is a oneliner contributed by Jonathan Noble at http://www.jonoble.com/. Thanks Lee.

(Get-Culture).TextInfo.ToTitleCase(“THIS IS MY STRING”.ToLower())

I am always in favor of shorter scripts nevertheless I also favor functions, so here is a much shorter function:

function ToProperCase ([String]$in){
return (Get-Culture).TextInfo.ToTitleCase($in.ToLower())
}

Re-Usable VBScript Functions – Part I

In this Multi-Part Series I will post lists on VBScript Functions and Subs that I have either found or written. I am a big fan of turning any useful code into a functions and adding it to my default VBScript Template, it saves a ton of time on the next scripting task. By no means am I claiming I wrote all of  these, most were just re-purposed into reusable functions. I hope you find these useful. In the later part of the series I will include my template I use to begin all my scripts.

Determine if the computer is a laptop:

?View Code VBSCRIPT
Function IsLaptop(strComputer)
    On Error Resume Next
    Set objWMIService = GetObject( "winmgmts://" & strComputer & "/root/cimv2" )
    Set colItems = objWMIService.ExecQuery( "Select * from Win32_Battery", , 48 )
    IsLaptop = False
    For Each objItem in colItems
        IsLaptop = True
    Next
    If Err Then Err.Clear
    On Error GoTo 0
End Function

Example of use

?View Code VBSCRIPT
If IsLaptop( "." ) Then
    WScript.Echo "Laptop
Else
    WScript.Echo "Desktop or server
End If


Shell out a command line with switches:

?View Code VBSCRIPT
Sub RunSwch(ByVal strRunCmd, strRunSwitch)
Dim objWshShell
    Set objWshShell = CreateObject("WScript.Shell")
    objWshShell.Run Chr(34) & strRunCmd & Chr(34)& " " & strRunSwitch, 1, True
    Set objWshShell = Nothing
End Sub

Example of use

?View Code VBSCRIPT
RunSwch "C:\Program Files\ApplicationX\Start.exe","/S /X /Log C:\log.log"


Shell out a command line without switches:

?View Code VBSCRIPT
Sub Run(ByVal strRunCmd)
Dim objWshShell
    Set objWshShell = CreateObject("WScript.Shell")
    objWshShell.Run Chr(34) & strRunCmd & Chr(34), 1, True
    Set objWshShell = Nothing
End Sub

Example of use

?View Code VBSCRIPT
Run "C:\Program Files\ApplicationX\Start.exe"
