I'm trying to write a script that checks my current public IP address to one that I've written in to see if it has changed. So far I've got this:
$NIP = "97.121.63.227"
$url = "http://checkip.dyndns.com"
$webclient = New-Object System.Net.WebClient
$Ip = $webclient.DownloadString($url)
$Ip2 = $Ip.ToString()
$ip3 = $Ip2.Split(" ")
$ip4 = $ip3[5]
$ip5 = $ip4.replace("</body>","")
$FinalIPAddress = $ip5.replace("</html>","")
$Prod = $NIP.CompareTo($FinalIPAddress)
$Prod
Whenever I run it though, comes up
Missing property name after reference operator.
At line:1 char:17
Pretty new to PowerShell and have no idea what I'm doing wrong
maybe you could use a regex to avoid multiple split and replace :
$NIP = "97.121.63.227"
$url = "http://checkip.dyndns.com"
$webclient = New-Object System.Net.WebClient
$Ip = $webclient.DownloadString($url)
$FinalIPAddress=[regex]::match($ip,"\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b").Value
$NIP -eq $FinalIPAddress
I was not able to reproduce the error unfortunately. Perhaps set a breakpoint (F9) at the top line and step through (F10) the script to narrow in on the cause. The error message is pointing to line 1...did you include that line in your example?

Cheers everyone,
I am getting the weirdest problem for which I need your helping ideas how to approach the issue.
So, I have a download script that pulls content off a company intranet using Webclient objects. It requires credentials and it is working on about 80% of the computers. The script pulls a listing using .DownloadString and then parses and gets some files using .DownloadFile.
On the machines that won't work the initial .DownloadString hangs until it appears to run into a timeout and returns $null.
User credentials are irrelevant on these types of machines meaning a user that works on another machine fails on this one.
Addresses, if entered into browser returns content.
Spoken in code I try it this way:
$wc = new-object System.Net.WebClient
$wc.Credentials = new-object System.Net.NetworkCredential($user, $pass, $domain)
$old_eap = $ErrorActionPreference
$ErrorActionPreference = "Stop"
try
{
$tmp = $wc.DownloadString($url)
if ([String]::IsNullOrEmpty($tmp))
{
throw "Intranet server did not return directory listing"
}
Return $tmp #the code is actually part of a function...
}
catch
{
write-error $_.Exception.Message
Return $null
}
finally
{
$ErrorActionPreference = $old_eap
}
I have no idea other than looking for changed settings between different machines. But which settings could be relevant for Webclient behaving like this? Any Ideas? I am seriously stuck...
I forgot... To make things a little easier I am stuck with Version 2.0 and we cant update yet. Bummer...
Thanks in advance

Maybe try to use xmlhttp as a client. Below is the usage example.
$url = "https://example.com/"
$http = New-Object -ComObject Msxml2.XMLHTTP
$user = "Domain\username"
$pwd = "password"
$utf = [System.Text.Encoding]::UTF8
$http.open("GET", $url, $false, $user, $pwd)
$http.send()
$result = $utf.GetString($http.responseBody)
I want to capture this 'text' shown int he picture below on a loop every minute, as this text changes every few minutes.
Here's the code I am using, and using HtmlAgilityPack.HtmlDocument
$metro = 'greatesthits'
$URL = "https://triplem.scadigital.com.au/stations/$metro/live"
[Reflection.Assembly]::LoadFile("C:\Users\makean\Downloads\htmlagilitypack.1.8.10\lib\Net45\HtmlAgilityPack.dll")
[HtmlAgilityPack.HtmlWeb]$web = #{}
[HtmlAgilityPack.HtmlDocument]$doc = $web.Load($url)
$doc.DocumentNode.SelectNodes(".//*[contains(#class,'sc-bdVaJa iHZvIS')]")
This is slimier code below, does the same thing, however just a different way of doing it
$metro = 'greatesthits'
$URL = "https://triplem.scadigital.com.au/stations/$metro/live"
Add-Type -path 'C:\Users\makean\Downloads\htmlagilitypack.1.8.10\lib\Net45\HtmlAgilityPack.dll'
$doc = New-Object HtmlAgilityPack.HtmlDocument
$wc = New-Object System.Net.WebClient
$doc.LoadHtml($wc.DownloadString($url))
$doc.DocumentNode.SelectNodes(".//*[contains(#class,'sc-bdVaJa iHZvIS')]")
This class sc-bdVaJa iHZvIS is a div and sits just a bit higher than PlayerNowPlaying__TrackInfo-kia103-1 gDXfGh and PlayerNowPlaying__TrackInfo-kia103-1 gDXfGh is what I want to capture, however when using this in my code, it returns blank.
How can I return just the text I want? Any help greatly appreciated.
I looked further at the thanks to the person above who pointed me in the right direction, checked the network option in Chrome 'inspect'. Grabbed the metadata from the stream URL.
$metro = '2classicrock'
$URL = 'https://wz2web.scahw.com.au/live/' + $metro + '_32.stream/playlist.m3u8'
$null = (Invoke-WebRequest -Uri $URL).RawContent -match '(https.*m3u8.*)'
$StreamURL = $Matches[0]
$streamMetaData = Invoke-WebRequest -Uri $StreamURL
$null = $streamMetaData.RawContent -match '#EXTINF:4.*?,(.*)'
$Matches[1]
I am trying to create a PowerShell script that will send an email if a service goes into a stopped state. I would like to be able to read the email configuration from another file.
Email configuration file:
.\emailconfig.conf
$emailSmtpServer = "smtp.company.com"
$emailSmtpServerPort = "587"
$emailSmtpUser = "usera"
$emailSmtpPass = "passwordb"
$emailFrom = "userA#company.com"
$emailTo = "userB#company.com"
$emailcc= "userC#company.com"
And this is what I have so far in the PowerShell script:
.\emailservicecheck.ps1
$A = Get-Service "Service B"
if ($A.Status -eq "Stopped") {
Get-Content emailconfig.conf | Out-String
$emailMessage = New-Object System.Net.Mail.MailMessage($emailFrom, $emailTo)
$emailMessage.Cc.Add($emailcc)
$emailMessage.Subject = "subject"
#$emailMessage.IsBodyHtml = $true # true or false depends
$emailMessage.Body = Get-Service "Service B" | Out-String
$SMTPClient = New-Object System.Net.Mail.SmtpClient($emailSmtpServer, $emailSmtpServerPort)
$SMTPClient.EnableSsl = $False
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($emailSmtpUser, $emailSmtpPass);
$SMTPClient.Send($emailMessage)
}
The script works if I enter the text from the email config file into the script but I cannot seem to be able to read in the data from the file on the fly and get the script to work. It errors out and says that my variables are empty.
What you are searching for, (I think) are .psd1 files. I personally prefer them (along with JSON) over the other configuration formats. The link I'm referring to also describes other well-known formats and how to use them in PowerShell.
In short, module manifests work as follows:
configuration.psd1
#{
SmtpServer = "";
MailFrom = "";
Auth = #{
User = "";
Pass = "";
};
}
Script.ps1
$mailConfig = Import-LocalizedData -BaseDirectory C:\ -FileName configuration.psd1
$emailMessage = New-Object System.Net.Mail.MailMessage( $$mailConfig.mailFrom , $mailConfig.mailTo )
As Mark already pointed out, Get-Content emailconfig.conf | Out-String will just output the content of the file, it won't define the variables in your code. For that you'd need to dot-source the file, which requires a file with the extension ".ps1".
If you want to stick with a simple config file format I'd recommend changing the file to something like this:
emailSmtpServer = smtp.company.com
emailSmtpServerPort = 587
emailSmtpUser = usera
emailSmtpPass = passwordb
emailFrom = userA#company.com
emailTo = userB#company.com
emailcc = userC#company.com
And importing it into a hashtable via ConvertFrom-StringData:
$cfg = Get-Content emailconfig.conf | Out-String | ConvertFrom-StringData
The data in the hashtable can be accessed via dot-notation ($cfg.emailFrom) as well as via the index operator ($cfg['emailFrom']), so your code would have to look somewhat like this:
$msg = New-Object Net.Mail.MailMessage($cfg.emailFrom, $cfg.emailTo)
$msg.Cc.Add($cfg.emailcc)
$msg.Subject = 'subject'
$msg.Body = Get-Service 'Service B' | Out-String
$smtp = New-Object Net.Mail.SmtpClient($cfg.emailSmtpServer, $cfg.emailSmtpServerPort)
$smtp.EnableSsl = $false
$smtp.Credentials = New-Object Net.NetworkCredential($cfg.emailSmtpUser, $cfg.emailSmtpPass)
$smtp.Send($msg)
It looks like what you're trying to do is include some script from another file. This can be done by dot sourcing, however the file needs to be saved as a .ps1 file, you can't use .conf.
You'd do it as follows (in place of your existing Get-Content) line:
. .\emailconfig.ps1
Assuming the file is kept in the current working directory of the script.
Your script wasn't working because
get-content emailconfig.conf | Out-String
Was returning the contents of that file to the output pipeline, rather than including it in the script and executing it.
I'm not sure i understood correctly what you want.
If you want to use variables from external file, you need to dot source your external script, for example, create a file named variables.ps1 and put in the same folder
In the beginning of the main script use
. .\variables.ps1
If you are after expanding variables that are in external file to ues as an email template please do as following:
$HTMLBody = get-content "yourfilepath" | Foreach-Object {$ExecutionContext.InvokeCommand.ExpandString($_)}
This will expand all variables and put it in the $HTMLBody variable
Then use:
$emailMessage.Body = (ConvertTo-Html -body $HTMLBody)
I have a PowerShell script, whose objective is to convert an incoming JSON object into a different sort of JSON object. (The "why" falls outside of the scope of this question.) The script (so far) is below (URL is obfuscated and will not work):
function Map-TempStudents {
param($uffStudent) # JObject containing UFF-formatted student
[String]$districtCode = $uffStudent.Item("DistrictCode").ToString()
Write-Host "districtCode = " $districtCode
$tempStudent = New-Object -TypeName Newtonsoft.Json.Linq.JObject
$tempStudent.Add("DistrictNum", $uffStudent.Item("DistrictCode").ToString())
Write-Host "tempStudent(DistrictNum) = " $tempStudent.Item("DistrictNum").ToString()
}
$currentPath = Split-Path -parent $MyInvocation.MyCommand.Definition
$jsonNetPath = $currentPath + '\Newtonsoft.Json.dll'
Add-Type -Path $jsonNetPath
$wc = New-Object system.Net.WebClient;
$studentPersonal = $wc.downloadString("http://test.foo.org/StudentPersonal")
$json = [Newtonsoft.Json.Linq.JObject]::Parse($studentPersonal)
$studentPersonal | Out-File "test.txt" # DEBUG
$studentBases = $json.Item("Data").Item("AssignTeacher")
Map-TempStudents -uffStudent $studentBases[0]
Running this script gives the following output:
districtCode = 0745
tempStudent(DistrictNum) = 485
To be clear, "0745" is the correct value, and "485" is the unexpected value.
I would expect tempStudent(DistrictNum) to be "0745" as well.
Why would this value change like this?
I was able to reproduce your issue with the following script (assuming Newtonsoft.Json.dll is already loaded into PowerShell):
$jo = New-Object -TypeName Newtonsoft.Json.Linq.JObject
$jo.Add("foo", "0745")
Write-Host $jo.Item("foo").ToString()
The Add method on JObject accepts an object as its second argument. If you pass a numeric string with a leading zero (and all the digits are less than 8), it is interpreted as an octal number. Hence "0745" gets converted into "485". This must be a PowerShell thing, because the equivalent code in C# works correctly:
JObject jo = new JObject();
jo.Add("foo", "0745");
Console.WriteLine(jo["foo"].ToString());
To prevent the unwanted conversion in PowerShell, wrap your string in a JValue before passing it to JObject.Add(), e.g.:
$jval = New-Object -TypeName Newtonsoft.Json.Linq.JValue -ArgumentList "0745"
$jo.Add("foo", $jval)
Here is the corrected Map-TempStudents function:
function Map-TempStudents {
param($uffStudent) # JObject containing UFF-formatted student
$districtCode = New-Object -TypeName Newtonsoft.Json.Linq.JValue -ArgumentList $uffStudent.Item("DistrictCode").ToString()
Write-Host "districtCode = " $districtCode.ToString()
$tempStudent = New-Object -TypeName Newtonsoft.Json.Linq.JObject
$tempStudent.Add("DistrictNum", $districtCode)
Write-Host "tempStudent(DistrictNum) = " $tempStudent.Item("DistrictNum").ToString()
}
I am trying to download a file from reporting services. The first time I run this code it works fine, but the next time it wont overwrite the first ones downloaded file. I have tried adding Remove-Item $file before I create the WebClient object, but when I do this I get the error The process cannot access the file 'D:\Work\RawMaterialCodes.xls' because it is being used by another process., the process being Powershell itself. I have tried calling $webClient.Dispose() thinking this might release the file, but no luck.
Does anyone have any ideas how I can overwrite the downloaded file and/or remove it before the next download attempt?
$reportServer = "http://localhost/ReportServer_TRITON"
$reportName = "RawMaterialCodes"
$file = "D:\Work\RawMaterialCodes.xls"
$startDate = "2014-01-22"
$endDate = "2014-01-24"
$category = "Cat1"
$destination = ""
$reportUrl = $reportServer + "?/" + $reportName + "&StartDate=" + $startDate + "&EndDate=" + $endDate + "&Category=" + $category + "&Destination=" + $destination + "&rs:Format=Excel"
$webClient = new-object System.Net.WebClient
$webClient.Credentials = New-Object System.Net.NetworkCredential($userName, $password, $domain)
$webClient.DownloadFile($reportUrl, $file)
$mailMessage = new-object System.Net.Mail.MailMessage
$mailMessage.From = $emailFrom
$mailMessage.To.Add($emailTo)
$mailMessage.Subject = $emailSubject
$mailMessage.Body = $emailBody
$attachment = new-object System.Net.Mail.Attachment($file, 'text/plain')
$mailMessage.Attachments.Add($attachment)
$smtpClient = New-Object System.Net.Mail.SmtpClient($smtpServer, 25)
$smtpClient.EnableSsl = $enableSsl
if ($smtpAuthUsername -ne "")
{
$smtpClient.Credentials = New-Object System.Net.NetworkCredential($smtpAuthUsername, $smtpAuthPassword)
}
$smtpClient.Send($mailMessage)
$mailMessage is keeping an open handle to your file. Add
$mailMessage.Dispose()
at the end of the script and you should be able to overwrite.
I don't see anything wrong with the code as you have it written. Disposing the WebClient is unnecessary here with respect to freeing up the file as it doesn't keep a handle to it. The most likely cause of this error is another piece of your code or another program which is opening the file and not properly disposing of it.
I would first assume it was my code at fault and carefully audit any other place I manipulated this file and see if I accidentally left a handle to it open
