Powershell Tray Icon Sample

The powershell samples for popping a tray icon weren't complete.  Here is a simple example (pops for 5 seconds) that I'm using to regularly remind me to stand/stretch/focus my eyes on distant objects. I've wrapped it in a scheduled task that calls powershell passing this script as the arg starting every weekday at about the time I start work repeating every 20 minutes.

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

$m = (Get-date).Minute

<# This is multi-line comment syntax #>
# Console.Write equivalent:
#Write-Host $m

$objNotifyIcon = New-Object System.Windows.Forms.NotifyIcon
$objNotifyIcon.Icon = "C:\Someplace\YourTrayIcon.ico"
$objNotifyIcon.BalloonTipIcon = "Warning"
$objNotifyIcon.BalloonTipTitle = "Hocus Focus"

if ($m -lt 30)
{
$objNotifyIcon.BalloonTipText = "Focus your eyes distant and blink frequently"
}
else
{
$objNotifyIcon.BalloonTipText = "Focus eyes & stretch too"
}

$objNotifyIcon.Visible = $True
$objNotifyIcon.ShowBalloonTip(1) #Not sure what the heck this millisecond param is even for; it stays until you hide it.

Start-Sleep -Seconds 5
$objNotifyIcon.Visible = $False
