WebClient.UploadFile: $client = New-Object System.Net.WebClient $client.Credentials = New-Object System.Net.NetworkCredential("user", "password") $client.UploadFile("ftp://ftp:50000/test.zip", "C:\HML-V-DC.zip")
When using this script on one computer I am able to upload a file directly to my FTP serve without any issues
But when running this on another machine in another location I get an error "You cannot call a null-valued expression"
Powershell version on computer that is not working: PSVersion 5.1.14393.3866
Powershell version on computer that is working: PSVersion 5.1.19041.610

Was hoping someone with some quick insight may be able to help me understand what I am missing here.
Thank you
Remove "WebClient.UploadFile: " from the line
$client = New-Object System.Net.WebClient

I have the following PowerShell code which creates a PST file
enter code Add-Type -assembly "Microsoft.Office.Interop.Outlook"
$Outlook = New-Object -comobject Outlook.Application
$namespace = $Outlook.GetNameSpace("MAPI")
$namespace.AddStore("C:\tmp\file.pst")
Running this code locally works excellent, but I have to run this code remotely. The script is sitting on the Windows machine and I'm starting it from Linux using WinRM (python) in that setup, it hangs on AddStore(). I assume this is related to user/security context but I can't find the resolution or info if it is possible to run it with some configuration changes.
EDIT: Ok, it is not hanging it just taking a long time before it will fail with the following error:
New-Object : Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed

CO_E_SERVER_EXEC_FAILURE means Outlook.exe and your code are running in different security contexts, and hence the COM system refuses to marshal calls between the two processes.
Firstly, Outlook cannot be used from anything that runs outside of an interactive user context (such as service or a scheduled task). Secondly, does it work if Outlook is not yet running on the target machine?
That being said, Extended MAPI (C++ or Delphi only) code runs in-proc might be able to do the job. If C++ or Delphi are not an option, you can try Redemption (any language - I am its author) - RDOSession.LogonPstStore is probably what you need - it creates and deletes a temporary profile that loads the specified PST file.
I am trying to start the web automation with using Chrome driver and Selenium. But I am getting an error that, web driver was not loaded. Below is my code entered. If someone could help me to correct this and start to automate would be appreciated.
Import-Module 'C:\AHKM\ChromeAutomation\WebDriver.dll'
$WebDriver = New-Object OpenQA.Selenium.Chrome.ChromeDriver
$WebDriver.Navigate().GoToUrl('www.google.com')
Error is below:
You cannot call a method on a null-valued expression.

+ $WebDriver.Navigate().GoToUrl('www.google.com')
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException

We resolved this issue by supplying the folder where chromedriver.exe is located, e.g.
$WebDriver = New-Object OpenQA.Selenium.Chrome.ChromeDriver -ArgumentList "C:\TEMP"
I am working on a deployment script for some software, and my script is working on probably 90% of the machines it runs on, but on the other 10%, I get a failure in the download portion. Here is what I have:
$tls = "Tls";
$Token = "#ZorusKey#";
[System.Net.ServicePointManager]::SecurityProtocol = $tls;
$source = <Source>
$destination = "C:\installers\ZorusInstaller.exe";
$WebClient = New-Object System.Net.WebClient
$WebClient.DownloadFile($source, $destination)
I have created the C:\installers folder on all target machines, so I don't think that's the problem. When run as a script, I get the following exception:
Exception calling "DownloadFile" with "2" argument(s): "An exception occurred during a WebClient request."
At C:\Windows\system32\config\systemprofile\AppData\Local\f1e96243cb9c4ef0b0336a152ed8827f.ps1:8 char:1
+ $WebClient.DownloadFile($source, $destination)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : WebException
Which then causes the following steps to fail, as the downloaded file doesn't exist.
I have also taken the step on several of the failing machines of running each line of the script above one at a time (copied / pasted from the same Powershell ISE window) and the download works without issue. looking for a possible reason / resolution.
Thanks in advance.
I'm using the Invoke-Expression cmdlet in PowerShell to load modules.
The following code works as intended.
$url="http://pastebin.com/raw/FuxtpN69"
IEX (New-Object System.Net.Webclient).DownloadString($url)
But when I try using variables to split the domain and the page.
$u="http://pastebin.com"
$rl="/raw/FuxtpN69"
$url="$u$rl"
IEX (New-Object System.Net.Webclient).DownloadString($url)
I get the following path error:
Exception calling "DownloadString" with "1" argument(s): "The given path's format is not supported."
At line:8 char:53
+ IEX (New-Object System.Net.Webclient).DownloadString <<<< ($url)
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
Can someone help me? Thanks in advance.
I think you are running PowerShell as a different account (for example an administrator).
Maybe that account's proxy settings are different that your normal account's?
See the credentials part first,
$webClient.UseDefaultCredentials = $true
Then, Try setting
$client.Proxy = $null
before downloading and see if it helps.
I'm trying to use FTP to upload a file to an FTP server. I found the following script online, but I can't get it to work.
$UserName = 'username'
$Password = 'password'
$LocalFilePath = 'c:\FolderName\x.txt'
$RemoteFileName = 'x.txt'
$ServerName = 'my.ftpserver.co.uk'
$webclient = New-Object System.Net.WebClient
$webclient.Credentials = New-Object System.Net.NetworkCredential($UserName, $Password)
#Connect to FTP
$uri = New-Object System.Uri(“ftp://$ServerName/$RemoteFileName”)
write-host $uri
#upload as file
$webclient.UploadFile($uri, $LocalFilePath)
But when I run this I get the following error:
Exception calling "UploadFile" with "2" argument(s): "An exception occurred during a WebClient request."
At line:21 char:22
+ $webclient.UploadFile <<<< ($uri, $LocalFilePath)
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
Can anyone point me in the right direction?
I can connect using Filezilla etc from my PC, so it's not blocked by the firewall or anything,
Tested your script and it runs fine, only way I'm able to reproduce your error is if I point $LocalFilePath to a file that doesn't exist. Could you try:
Test-Path($LocalFilePath)
And see if it returns True?
From your comment and the code I see in the question the issue could just be the fact that you have smart quotes in there. It would be a product of your coding editor or the source of copying and paste that code into your environment. You need to watch out for these things. Assuming the paths are correctly formed perhaps that is just your issue.
Smart Quotes
$uri = New-Object System.Uri(“ftp://$ServerName/$RemoteFileName”)
Proper double quotes
$uri = New-Object System.Uri("ftp://$ServerName/$RemoteFileName")
The quotes in the second example are the ones you should use.
