This just a test post to see how well I can get code from ISE to look good on the blog, almost like a screen shot, but not actually be a screen shot, be totally copy and pastable.

This is just testing different techniques for results and procedure efficiency.

So far so good.

$frequency = 2000            
            
$signature = @"
    [DllImport("kernel32.dll")] public static extern bool Beep(int freq,int duration);
"@            
            
Add-Type -MemberDefinition $signature -Name "Beeper" -Namespace Win32Functions -PassThru            
            
For ($i = 500 ; $i -le 1500 ; $i += 100)            
{            
    [Win32Functions.Beeper]::Beep($frequency,300)            
    Start-Sleep -Milliseconds $i            
}            
            
[Win32Functions.Beeper]::Beep($frequency,3000)

$option1 = New-Object System.Management.Automation.Host.ChoiceDescription("&Yes","You chose yes...")            
$option2 = New-Object System.Management.Automation.Host.ChoiceDescription("&No","You chose no...")            
$choices = [System.Management.Automation.Host.ChoiceDescription[]]($option1, $option2)            
$chosen = $host.ui.PromptForChoice("Error Background","Do you want error background to be white?",$choices,1)            
            
If ($chosen -eq 0) {$Host.PrivateData.ErrorBackgroundColor = "white"}            
            
$LessonNumber = Read-Host "Enter Lesson Number"            
$now = Get-Date -Format 'dddd-hhmmtt'            
Start-Transcript "C:\transcripts\PowerShell-Class-Lesson-$LessonNumber-Transcript-$now.txt"            
#Start-Transcript ("C:\transcripts\PowerShell-Class-Lesson-$LessonNumber-Transcript-{0:dddd-hhmmtt}.txt" -f (Get-Date))

Get-Process | Where-Object {$_.ws -gt 100MB}

can be simplified to this:

            
Get-Process | Where ws -gt 100MB

The reason I didn't like it up front was because you still really have to understand the first more complex example because the simplified syntax can only do very simple comparisons.  You cant do complex comparisons like joining two conditions with a –and operator.

It did finally grow on me though, and now, when no one is looking, I really love the newer simplified syntax.  So much so that when I have a –and situation, I actually have caught myself lately using two adjacent where-object instead of one using the simplified syntax.  I am sure there is ghastly performance impact of this, but for simple stuff, it works fine.  Now this wouldn't work for the –or operator, but it works great for –and.

Get-Process | Where-Object {$_.ws -gt 100MB -and $_.pm -gt 100MB}

can be written using two simplified where-object cmdlets

        
            
Get-Process | Where ws -gt 100MB | where pm -gt 100MB

Is this wrong?

I think from a pure coding standpoint its not a good behavior, but PowerShell’s target audience is admins.  PowerShell is a means to an end, it is not the end for admins.  I think simplicity and readability are huge and because of that I don't think this is too wrong.  You still cant get away without knowing the more complex –filterscript syntax, but this does seem more fun.

What do you think?

Yours truly is going to be delivering two sessions at the upcoming PowerShell Saturday event at the
Microsoft Office in Alpharetta.  It should be a blast, and went really well in Ohio (Columbus) and 
North Carolina (Charlotte).  Check out in info below.  I am pretty sure there are still some more seats
left, but don't wait too long!

  LOVE Windows PowerShell so much, and realize the value of Windows PowerShell
  that they are willing to give up their Saturday to learn the stuff.
• It will be of immediate value – with three tracks of information –
  Introductory PowerShell, Advanced PowerShell, and Applied PowerShell, there will
  be plenty of new things to learn!
• The first official Iron Scripter event – put your scripting skills to the
