Powershell and jobs

Powershell jobs are a bit of blunt instrument.

Here's two options for sending inputs for them
Scenario 1: Sending a string with all of our values and splitting them to an array when inside the scriptblock.

	$inputString = "text1;text2;text3"
	start-job -ArgumentList $inputString -ScriptBlock {
	$listItems = @($args[0]).split(";")
	write-output "I got $($listItems.count) items with me..."
	foreach ($listItem in $listItems) {
	write-output "Item: $listItem"
	}
	} -Name "Test"
	get-job |where-object {$_.name -like "Test"} |receive-job -AutoRemoveJob -wait

Scenario2: Sending an object as input. Handy for configs and saves the need to define variablenames.

	$ScriptPath = $(split-path -Parent $MyInvocation.MyCommand.Definition)
	$inputs = new-object PSObject -Property @{url="Test48"; State="Added";scriptPath=$ScriptPath}
	start-job -InputObject $inputs -ScriptBlock {
	$data = @($input)
	write-output "My output: $($data)"
	write-output "url: $($data.url)"
	write-output "state: $($data.state)"
	write-output "scriptpath: $($data.scriptpath)"
	} -Name "Test"
	get-job |where-object {$_.name -like "Test"} |receive-job -AutoRemoveJob -wait

powershell assisting with mails

ExtractAttachedMails.ps1 is used for extracted alla attached mails in a outlook .msg-file to specified folder.
CatalogueMails.ps1 is used for indexing the mails to more easily filter on timestamps and senders.

This came in handy when a happy user sent me 45 attached mails with the same subjectline so the extractionprocess also throws in an indexnumber to avoid namingconflicts.

	$scriptPath = $(split-path $myinvocation.mycommand.definition)
	$outputPath = "$($scriptPath)\extractedMails"
	$mails = get-childitem -Filter *.msg -Path $outputPath
	$object = @()
	foreach ($mail in $mails) {
	$outlook = new-object -ComObject Outlook.application
	try { $msg = $outlook.session.openshareditem($mail.fullname)
	$tempObject = new-object psobject -Property @{body=$msg.body;Topic=$msg.ConversationTopic;to=$msg.to;timestamp=$msg.SentOn }
	$object += $tempObject
	}
	catch { write-output "Coulnd't open $($mail.fullname)"}
	}
	$object |sort-object timestamp -Descending |select timestamp,Topic,to
	$object |sort-object timestamp -Descending |select timestamp,Topic,to |export-csv -Path "$($scriptpath)\output.csv" -NoTypeInformation -Encoding UTF8
	write-output "Total count: $($mails.count)"

	if ($mails -ne $null) {
	$index = 0
	foreach ($mail in $mails) {
	$outlook = new-object -ComObject Outlook.application
	$msgFn = $mail.FullName
	$msg = $outlook.CreateItemFromTemplate($msgFn)
	foreach ($attachment in $msg.Attachments) {
	if ($attachment.FileName -like "*.msg") {
	$attFn = "$outputPath\$($index)_$($attachment.FileName)"
	$attachment.SaveAsFile($attFn)
	$index++
	}
	else {write-output "Skipping, not a msg ($($attachment.filename))"}
	}
	}
	write-output "Total count: $($mails.count). Extracted $index attachements"
	}
	else { write-output "No mails found $inputPath"}
