i made this script in powershell, but i'm not doing something correctly (I'm trying to learn self-taught uwu)
This is the script in question.
function Get-DesiredProcess {
$DesiredProcess=Read-Host "Welcome to de advanced task manager! Choose an action to do: 1. WUP (WindowsUpdate) 2. MDP (ProxyModification)"
Switch ($DesiredProcess)
{
WUP {$ChosenProcess=Install-WUpdate}
MDP {$ChosenProcess=Set-Proxy}
}
If ($DesiredProcess -eq $null) {
Write-Error "You must specify an action!"
return Get-DesiredProcess
}
Else {
Set-Variable -Name "DesiredProcess" -Value "ChosenProcess"
}
}
Get-DesiredProcess
Write-Output $DesiredProcess
Write-Output $ChosenProcess
The 2 last "Write-Output" are just for testing if it did registry the variables correctly or not (spoiler, it didn't)
When the Read-Host have not been answered, it should output "You specify an action!" but does nothing:
Welcome to de advanced task manager! Choose an action to do: 1. WUP (WindowsUpdate) 2. MDP (ProxyModification):
PS C:\Users\user1\Documents\scriptsfiles>
And when a choice is made, it should keep the variable with this part:
Set-Variable -Name "DesiredProcess" -Value "ChosenProcess"
Instead of that it executes directly the choosen process...
Thanks in advance!
If you want your function to set a new value to a variable defined outside the function, use scoping inside the function, so
$ChosenProcess = 'Install-WUpdate' --> $script:ChosenProcess = 'Install-WUpdate'.
However, easier to understand is to have your function output something the rest of the code can deal with. In this case, since you want both what the user typed in, AND what the chosen process for that input would be, I would suggest having the function output an object that has both properties like:
function Get-DesiredProcess {
# inside the function both variables have LOCAL scope
$ChosenProcess = $null # initialize to nothing, or an empty string
$DesiredProcess = Read-Host "Welcome to de advanced task manager! Choose an action to do: 1. WUP (WindowsUpdate) 2. MDP (ProxyModification)"
switch ($DesiredProcess) {
'WUP' {$ChosenProcess = 'Install-WUpdate'}
'MDP' {$ChosenProcess = 'Set-Proxy'}
default {
Write-Warning "You did not specify an accepted action. Type 'WUP' or 'MDP'"
Get-DesiredProcess
}
}
# only output if there is a matching chosen process
if (![string]::IsNullOrWhiteSpace($ChosenProcess)) {
# now have the function return both what the user typed and what the chosen action should be
[PsCustomObject]#{
DesiredProcess = $DesiredProcess
ChosenProcess = $ChosenProcess
}
}
}
$result = Get-DesiredProcess
Using this would output something like
Welcome to de advanced task manager! Choose an action to do: 1. WUP (WindowsUpdate) 2. MDP (ProxyModification): 7
WARNING: You did not specify an accepted action. Type 'WUP' or 'MDP'
Welcome to de advanced task manager! Choose an action to do: 1. WUP (WindowsUpdate) 2. MDP (ProxyModification): wup
DesiredProcess ChosenProcess
-------------- -------------
wup Install-WUpdate
Now, the following code can simply act on what is in variable $result.ChosenProcess
What I understand after reading your description, you need to declare all of the variables as global otherwise you need to access those variables inside of the function. A function variable can not be accessible from outside of the function. As per my understanding from your description, your code will be like this:
function Get-DesiredProcess
{
$DesiredProcess=Read-Host "Welcome to de advanced task manager! Choose an action to do: 1. WUP (WindowsUpdate) 2. MDP (ProxyModification)"
switch ($DesiredProcess)
{
1 {$ChosenProcess="Install-WUpdate"}
2 {$ChosenProcess="Set-Proxy"}
}
If ($DesiredProcess -eq [string]::empty)
{
Write-Error "You must specify an action!"
Get-DesiredProcess
}
Else
{
Set-Variable -Name "DesiredProcessName" -Value "$ChosenProcess"
Write-host "You chose this: "$DesiredProcessName
}
}
Get-DesiredProcess
I found a script to download windows updates that I've been tweaking to fit my needs. It seems to work fine except I can't figure out how to remove the optional updates before downloading. I've found that the "Critical", "Important", and "Moderate" updates will have a MsrcSeverity value of one of those 3 words, where optional will be blank. How do I remove the updates with no msrcseverity value from the list before downloading??
Here's the whole code...
$global:scriptpath = $MyInvocation.MyCommand.Path
$global:dir = Split-Path $scriptpath
$global:logfile = "$dir\updatelog.txt"
write-host " Searching for updates..."
$session = New-Object -ComObject Microsoft.Update.Session
$searcher = $session.CreateUpdateSearcher()
$result = $searcher.Search("IsInstalled=0 and Type='Software' and IsHidden=0")
if ($result.Updates.Count -eq 0) {
Write-Host "No updates to install"
}
else {
$result.Updates | Select Title
$result.Title >> $logfile
}
$downloads = New-Object -ComObject Microsoft.Update.UpdateColl
foreach ($update in $result){
$downloads.Add($update)
}
$count = $result.Updates.Count
write-host ""
write-host "There are $($count) updates available."
write-host ""
read-host "Press Enter to download\install updates"
$downloader = $session.CreateUpdateDownLoader()
$downloader.Updates = $downloads
$downloader.Download()
$installs = New-Object -ComObject Microsoft.Update.UpdateColl
foreach ($update in $result.Updates){
if ($update.IsDownloaded){
$installs.Add($update)
}
}
$installer = $session.CreateUpdateInstaller()
$installer.Updates = $installs
$installresult = $installer.Install()
$installresult
I have the "read-host" in there right now to stop it from downloading until I get this figured out. I've tried putting an extra pipe in $result.updates | Select Title | where {$result.Updates.MsrcSeverity -ne $null}, I've also tried that with just $result.MsrcSeverity and no go. I've tried the "where" pipe in a couple different places. I've also tried making an If statement in a couple places that says if the MsrcSeverity doesn't equal null then add it to the list. I've also tried adding onto the $searcher.Search( line with an and MsrcSeverity = 'Important'") just to test and that didn't do anything.
So far it still lists all the updates whether or not there's something in the MsrcSeverity column. Am I looking in the wrong place? It's the only thing I can see that tells the difference between an Important update and an Optional.
Thanks.
Search criterias are documented at IUpdateSearcher::Search method
The BrowseOnly=0 unfortunately doesn't exclude Optional updates as seen in Windows Update program. But AutoSelectOnWebSites=1 does.
"BrowseOnly=1" finds updates that are considered optional.
"BrowseOnly=0" finds updates that are not considered optional.
"AutoSelectOnWebSites=1" finds updates that are flagged to be automatically selected by Windows Update.
"AutoSelectOnWebSites=0" finds updates that are not flagged for Automatic Updates.
$session1 = New-Object -ComObject Microsoft.Update.Session -ErrorAction silentlycontinue
$searcher = $session1.CreateUpdateSearcher()
#Do not search for optional updates and exclude hidden
$result = $searcher.Search("IsInstalled=0 AND AutoSelectOnWebSites=1 AND IsHidden=0")
Thanks for all the help, everyone. I got so many helpful suggestions I didn't know where to begin...
I got it figured out, thanks.
I'm in the process of writing a PowerShell script to help in the process of setting up new PC's for my work. This will hopefully be used by more than just me so I'm trying to think of everything.
I have offline installers (java, flash, reader, etc) saved on our FTP server that the script downloads if a local copy hasn't already been saved in the Apps directory that gets created. Periodically the files on the FTP server will get updated as new versions of the programs are released. I want the script to have an option of checking for newer versions of the installers in case someone likes to carry around the local copies and forgets to check the server every now and then. It also will need to work in Windows 7 without any need to import additional modules unless there's an easy way to do that on multiple PC's at a time. I know about the import command, but the experiences I've had needed me to copy the module files into multiple places on the PC before it'd work.
Right now I haven't had much luck finding any solutions. I've found code that checks for modified dates on local files, or files on a local server, but nothing that deals with FTP other than uploading\downloading files.
Here's the last thing I tried. I tried a combination of what I found for local files with FTP. Didn't work too well.
I'm new to PowerShell, but I've been pretty good at piecing this whole thing together so far. However, this idea is becoming troublesome.
Thank you for the help.
$ftpsite = "ftp://ftpsite.com/folder/"

$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($ftp)
$webclient.DownloadFile($uri, $File)
}
UPDATE:
Here's what I have after Martin's help. It kind of works. It downloads the file from FTP, but it's not comparing the remote and local correctly. The remote file returns 20150709140505 and the local file returns 07/09/2015 2:05:05 PM. How do I format one to look like the other before the comparison, and is "-gt" the correct comparison to use?
Thanks!

Seems to be working! Here's the code. Thanks for the help!

You cannot use the WebClient class to check remote file timestamp.
You can use the FtpWebRequest class with its GetDateTimestamp FTP "method" and parse the UTC timestamp string it returns. The format is specified by RFC 3659 to be YYYYMMDDHHMMSS[.sss].
That would work only if the FTP server supports MDTM command that the method uses under the cover (most servers do, but not all).
$url = "ftp://ftpsite.com/folder/install_firefox.exe"
$ftprequest = [System.Net.FtpWebRequest]::Create($url)
$ftprequest.Method = [System.Net.WebRequestMethods+Ftp]::GetDateTimestamp
$response = $ftprequest.GetResponse().StatusDescription
$tokens = $response.Split(" ")
$code = $tokens[0]
if ($code -eq 213)
{
Write-Host "Timestamp is" $tokens[1]
}
else
{
Write-Host "Error" $response
}
It would output something like:
Timestamp is 20150709065036
Now you parse it, and compare against a UTC timestamp of a local file:
(Get-Item "install_firefox.exe").LastWriteTimeUtc
Or save yourself some time and use an FTP library/tool that can do this for you.
For example with WinSCP .NET assembly, you can synchronize whole remote folder with installers with a local copy with one call to the Session.SynchronizeDirectories. Or your can limit the synchronization to a single file only.
# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"
# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions
$sessionOptions.Protocol = [WinSCP.Protocol]::Ftp
$sessionOptions.HostName = "ftpsite.com"
$session = New-Object WinSCP.Session
# Connect
$session.Open($sessionOptions)
$transferOptions = New-Object WinSCP.TransferOptions
# Synchronize only this one file.
# If you remove the file mask, all files in the folder are synchronized:
$transferOptions.FileMask = "install_firefox.exe"
$session.SynchronizeDirectories(
[WinSCP.SynchronizationMode]::Local, "$dir\Apps", "/folder",
$False, $False, [WinSCP.SynchronizationCriteria]::Time,
$transferOptions).Check()
To use the assembly, just extract a contents of .NET assembly package to your script folder. No other installation is needed.
The assembly supports not only the MDTM, but also other alternative methods to retrieve the timestamp.
See also a related Powershell example that shows both the above code and other techniques.

First off I apologize for the extremely long, wordy post. It’s an interesting issue and I wanted to be as detailed as possible. I’ve tried looking through any related PowerShell posts on the site but I couldn’t find anything that helped me with troubleshooting this problem.
I've been working on a PowerShell script with a team that can send Wake-On-Lan packets to a group of computers. It works by reading a .csv file that has the hostnames and MAC’s in two columns, then it creates the WOL packets for each computer and broadcasts them out on the network. After the WOL packets are sent, it waits a minute and then pings the computers to verify they are online, and if any don’t respond it will display a window with what machines didn’t respond to a ping. Up until the final If/Else statement works fine, so I won't be going into too much detail on that part of the script (but of course if you want/need further details please feel free to ask).
The problem I’m having is with the final If/Else statement. The way the script is supposed to work is that in the ForEach loop in the middle of the script, the value of variable $PingResult is true or false depending on whether or not the computer responds to a ping. If the ping fails, $PingResult is $false, and then it adds the hostname to the $PingResult2 variable.
In theory if all of the machines respond, the If statement fires and the message box displays that it was a success and then the script stops. If any machines failed to respond, the Else statement runs and it joins all of the items together from the $PingResult2 variable and displays the list in a window.
What actually happens is that even if all of the machines respond to a ping, the If statement is completely skipped and the Else statement runs instead. However, at that point the $PingResult2 variable is blank and hence it doesn’t display any computer names of machines that failed to respond. In my testing I’ve never seen a case where the script fails to wake a computer up (assuming it’s plugged in, etc.), but the Else statement still runs regardless. In situations where the Else statement runs, I’ve checked the value of the $PingResult2 variable and confirmed that it is blank, and typing $PingResult2 –eq “” returns $true.
To add another wrinkle to the problem, I want to return to the $PingResult2 variable. I had to create the variable as a generic list so that it would support the Add method to allow the variable to grow as needed. As a test, we modified the script to concatenate the results together by using the += operator instead of making $PingResult2 a list, and while that didn’t give a very readable visual result in the final display window if machines failed, it did actually work properly occasionally. If all of the computers responded successfully the If statement would run as expected and display the success message. Like I said, it would sometimes work and sometimes not, with no other changes making a difference in the results. One other thing that we tried was taking out all of the references to the Visual Basic assembly and other GUI elements (besides the Out-GridView window) and that didn’t work either.
Any idea of what could be causing this problem? Me and my team are completely tapped out of ideas at this point and we’d love to figure out what’s causing the issue. We’ve tried it on Windows 7, 8.1, and the latest preview release of Windows 10 with no success. Thanks in advance for any assistance.
P.S Extra brownie points if you can explain what the regular expression on line 29 is called and how it exactly works. I found out about it on a web posting that resolved the issue of adding a colon between every two characters, but the posting didn’t explain what it was called. (Original link http://powershell.org/wp/forums/topic/add-colon-between-every-2-characters/)

The comparison in your If statement is incorrect because you are comparing $PingResult2, a List<string>, to a string. Instead, try
If ($PingResult2.Count -eq 0)
{
# Show the message box
}
Else
{
# Show the other message box
}
or one of countless other variations on this theme.
The regular expression in question uses a backreference to replace exactly two characters with the same two characters plus a colon character. I am unsure what exactly you are attempting to "define," though.
You are checking if a list has a value of a null string, rather than checking the number of items in the list.
If you change the if statement to the following it should work fine:
If($PingResult2.count -eq 0)
I'm guessing the regex is trying to insert a colon between every two characters of a string to represent 0123456789ab as 01:23:45:67:89:ab.
The code means if there is no hyphen or colon in the MAC, put in a colon every the characters, then split the address using colon as delimiter then represent each as a byte:
If($Computer.'MAC' -notmatch '([:]|[-])')
{
$Computer.'MAC' = $Computer.'MAC' -replace '(..(?!$))','$1:'
}
$MACAddr = $Computer.'MAC'.split('([:]|[-])') | %{ [byte]('0x' + $_) }
The other answer have explained quite well why your code does not work. I'm not going there. Instead I'll give some suggestions that I think would improve your script, and explain why I think so. Let's start with functions. Some of the things you do are functions I keep on hand because, well, they work well and are used often enough that I like having them handy.
First, your dialog to get the CSV file path. It works, don't get me wrong, but it could probably be better... As it is you pop up an Open File dialog with no parameters. This function allows you to use a few different parameters as wanted, or none for a very generic Open File dialog, but I think it's a slight improvement here:
Function Get-FilePath{
[CmdletBinding()]
Param(
[String]$Filter = "|*.*",
[String]$InitialDirectory = "C:\")
[void][System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms")
$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$OpenFileDialog.initialDirectory = $InitialDirectory
$OpenFileDialog.filter = $Filter
[void]$OpenFileDialog.ShowDialog()
$OpenFileDialog.filename
}
Then just call it as such:
$CSVFile = Get-FilePath -Filter "Comma Separated Value (.CSV)|*.CSV" -InitialDirectory "$env:USERPROFILE\Desktop"
That opens the dialog filtering for only CSV files, and starts them looking at their desktop (I find that a lot of people save things to their desktop). That only gets the path, so you would run your validation like you were. Actually, not like you were. You really seem to have over complicated that whole bit. Bit I'll get to that in a moment, first, another function! You call message boxes fairly often, and type out a bunch of options, and call the type, and everything every single time. If you're going to do it more than once, make it easy on yourself, make a function. Here, check this out:
Function Show-MsgBox ($Text,$Title="",[Windows.Forms.MessageBoxButtons]$Button = "OK",[Windows.Forms.MessageBoxIcon]$Icon="Information"){
[Windows.Forms.MessageBox]::Show("$Text", "$Title", [Windows.Forms.MessageBoxButtons]::$Button, $Icon) | ?{(!($_ -eq "OK"))}
}
Then you can specify as much or as little as you want for it. Plus it uses Type'd parameters, so tab completion works, or in the ISE (if that's where you're writing your script, like I do) it will pop up valid options and you just pick from a list for the buttons or icon to show. Plus it doesn't return anything if it's a simple 'OK' response, to keep things clean, but will return Yes/No/Cancel or whatever other option you choose for buttons.
Ok, that's the functions, let's get to the meat of the script. Your file validation... Ok, you pull the first line of the file, so that should just be a string, I'm not sure why you're splitting it and verifying each header individually. Just match the string as a whole. I would suggest doing it case insensitive, since we don't really care about case here. Also, depending on how the CSV file was generated, there could be quotes around headers, which you may want to account for. Using -Match will perform a RegEx match that is a bit more forgiving.
If((Get-Content $CSVFile -TotalCount 1) -match '^"?machine name"?,"?mac"?$'){
Show-MsgBox "The CSV File's headers must be Machine Name and MAC." 'Invalid CSV File headers!' -Icon Warning
break
}
So now we have two functions, and 5 lines of code. Yes, the functions take up more space than what you previously had, but they're friendlier to work with, and IMO more functional. Your MAC address correction, and WOL sending part are all aces so far as I'm concerned. There's no reason to change that part. Now, for validating that computers came back up... here we could use some improvement. Instead of making a [List] just add a member to each object, then filter against that below. The script as a whole would be a little longer, but better off for it I think.
Add-Type -AssemblyName Microsoft.VisualBasic,System.Windows.Forms
Function Get-FilePath{
[CmdletBinding()]
Param(
[String]$Filter = "|*.*",
[String]$InitialDirectory = "C:\")

$OpenFileDialog.initialDirectory = $InitialDirectory
$OpenFileDialog.filter = $Filter
[void]$OpenFileDialog.ShowDialog()
$OpenFileDialog.filename
}
Function Show-MsgBox ($Text,$Title="",[Windows.Forms.MessageBoxButtons]$Button = "OK",[Windows.Forms.MessageBoxIcon]$Icon="Information"){
[Windows.Forms.MessageBox]::Show("$Text", "$Title", [Windows.Forms.MessageBoxButtons]::$Button, $Icon) | ?{(!($_ -eq "OK"))}
}
#Get File Path
$CSVFile = Get-FilePath -Filter "Comma Separated Value (.CSV)|*.CSV" -InitialDirectory "$env:USERPROFILE\Desktop"
#Validate Header
If((Get-Content $CSVFile -TotalCount 1) -match '^"?machine name"?,"?mac"?$'){
Show-MsgBox "The CSV File's headers must be Machine Name and MAC." 'Invalid CSV File headers!' -Icon Warning
break
}
$ComputerList = Import-Csv -Path $CSVFile |
Out-GridView -PassThru -Title "Select Computers to Wake up"
ForEach($Computer in $ComputerList)
{
If($Computer.'MAC' -notmatch '([:]|[-])')
{

}

[void] $UDPclient.Send($packet, $packet.Length)
write "Wake-On-Lan magic packet sent to $($Computer.'Machine Name'.ToUpper())"
}

Ok, I'm going to get off my soap box and go home, my shift's over and it's time for a cold one.

Every time I type out an IM message to someone else, it does what I'm trying to do for incoming messages. But nothing ever fires for those, just outgoing. I've been through all the documentation, and there aren't any other candidate events, I'm sure it's this one. But the Modality object just stores some stuff about whether it's an IM or screensharing and the like, nothing useful.

Where am I screwing up on this? I prefer answers in Powershell, but I don't think this is a problem specific to Powershell, so if you know how to do it in C# or Visual Basic or something like that, I'd appreciate that too.
I don't have Lync so I can test this myself, but take a look at this link where it shows how to use the API.
The problem is(from what I understand) that there is a modality per participant per media. So for a conversation with two members using only text, there will be 2 modalities, one for incoming messages(from the remote participant) and one for outgoing. This is specified here in
Occurs when an instant message is received, or sent if the InstantMessageModality belongs to the local participant.
Source: MSDN
When you register your object-event, you register it to "your modality", and not the remote modality. To fix it it seems to you need to take each conversation from the manager, look at each participant except the one representing you (check the IsSelf property). Then take the modality from the participants(except yourself) and register for the InstantMessageReceived event.
At least that's what I got out of it, but as said I have no experience with Lync so I could easily be wrong.
My guess at how it could be done(VERY untested):
# What do we do here? You get the manager the keeps track of every conversation
$conversationMgr = $client.ConversationManager
# Register events for existing conversations.
#You may need to use '$conversation in $conversationMgr.GetEnumerator()'
foreach ($conversation in $conversationMgr) {
#Get remote participants
$conversation.Participants | where { !$_.IsSelf } | foreach {
#Get IM modality
$textmod = [InstantMessageModality]($_.Modalities[ModalityTypes.InstantMessage])
Register-ObjectEvent -InputObject $textmod -EventName "InstantMessageReceived" `
-SourceIdentifier "new im $i" `
-action {
#...
}
}
}
