I'm trying to disable/enable input devices in my laptop (win10), automatically (.reg file, python code etc)
I tried to use DevCon but after a lot of attempts it didn't work out for my touchpad and keyboard (I tried to disable, remove).
I searched the web and the solutions don't completely disable the devices (for example: Ctrl+Alt+Delete is not blocked).
I work on a windows 10 Laptop, You can assume that you have admin Privileges.
Have to check for Keyboard but for Mouse and Touchpad, you can use some Powershell commands to check and find out the actual device Classes and InstanceIDs and then turn off with an Admin elevated Powershell prompt.
The InstanceIDs of Mouse and Touchpad is different on different brands and types of Laptops, but first you can identify those with their Classes such as HIDClass. To get that fire up Powershell prompt(you've already tried REG and Python, so assuming you'll be okay with Powershell too (.ps1)) and run this command:
Get-PnpDevice | Where-Object {$_.Class -eq 'HIDClass'}
This may show 2 or 3 entries of which 1 belongs to Mouse and other to Touchpad, this would be a bit of trial and error, you have to pick any InstanceID to make filter more target specific and fire-up admin-elevated Powershell (search Powershell and click on "Run As Administrator") and run Disable-PnpDevice method like below(if InstanceId contains "ACPI"):
Get-PnpDevice | Where-Object {$_.Class -eq 'HIDClass' -and $_.InstanceId -like 'ACPI*'} | Disable-PnpDevice -Confirm:$false
This will disable Touchpad(in mine(Lenovo) it did disabled it) and then you can try out another InstanceID and disable the Mouse too in the same way. Voila !! both are turned off now.
If you prefer this in .ps1 script format then you need a self-elevating script which can enable/disable the devices without any halts, save this code in .ps1 file and then right-click > Run with PowerShell:
$Loc = Get-Location
"Security.Principal.Windows" | % { IEX "( [ $_`Principal ] [$_`Identity ]::GetCurrent() ).IsInRole( 'Administrator' )" } | ? {
$True | % { $Arguments = #('-NoProfile','-ExecutionPolicy Bypass','-NoExit','-File',"`"$($MyInvocation.MyCommand.Path)`"","\`"$Loc\`"");
Start-Process -FilePath PowerShell.exe -Verb RunAs -ArgumentList $Arguments; } }
Get-PnpDevice | Where-Object {$_.Class -eq 'HIDClass' -and $_.InstanceId -like 'ACPI*'} | Disable-PnpDevice -Confirm:$false
Read-Host
Note: If you in case disable the wrong or undesired device than for enabling it, in the same admin-elevated Powershell window run the same filter command (the Get-PnpDevice with filters) and replace Disable-PnpDevice with Enable-PnpDevice.
Let me know in comments if you still face issue with above commands.
Untested, but calling BlockInput() should do what you want. It blocks both keyboad and mouse input. It is however defined in user32.dll so you will need to use ctypes to access it:
import ctypes
ctypes.windll.user32.BlockInput(True)

So, I believe my issue is that PowerShell is unable to access the memory space of the file system, from within the memory block, of my thread, is there a way to solve this, to access the file system, from a multi-threaded application?
Back Story:
So, I run a program, that calls upon "code"/command, from the command prompt, (*.exe) (Robocopy) to copy files from a server, to a group of computers, at a time. We have a classroom environment, at my work, so I have my setup, in a way, that I have a folder, per room. I keep a list of all our addresses (static), for each room, in their perspective folders. We have an update, from our developers, that we need to push to all of the rooms. We need to run a slow push, as to not disturb the production environment. It's proprietary, so we can't use a/any typical solution(s), like Microsoft SCCM. So, I created a script to push to the rooms. while it does work, it's not a smooth operation. I'm not actually the one pushing the update, because of the slow process, of updating. I'm just trying to make a stable smooth-running package, for the person, who is going to be doing it. My code works, outside of the thread, (I) tested it, I know it works.
So how I came my conclusion of knowing, that my code works outside of the thread. (The picture) I followed the same setup, with my code, (A button click event inside of a thread, running the form). Placed the actual working code, (tried, and tested, before making a Thread, for the interface, after completing backend operation code testing.)
("Region Boe's Addition") referring to Boe Prox, (from the link)
In his, he is updating from a command line/powershell window, via a function run inside a thread. I'm running an event from a button, inside of a thread and trying to run a separate thread, for the click event(s). Outside of the thread. The event works fine, but inside, it doesn't work, at all..
Basic Code:
// Multi thread, thread for the $form, and thread for the event (as per referenced link)
$var = [PowerShell]::Create().AddScript({ button.Add_Click{
$var = [PowerShell]::Create().AddScript{<Thread><Robocopy></Thread>}
})
Needed the "Start-Process" -Wait command to allow for the listbox, to be updated in-between copies, to confirm installation, through each step in the loop.
$choice = $comboBox.SelectedItem
# $drive = Get-Location
if(!(Test-Path -PathType Container -Path "L:\$choice"))
{
# New-Item -ItemType "container" -Path . -Name $choice
New-Item -ItemType "Directory" -Path . -Name $choice
}
# $folder = $_
# Where is it being stored at?
[System.IO.File]::ReadLines("Y:\$choice\IPs.txt") | foreach {
ping -a -n 2 -w 2000 $_ | Out-Null
Test-Connection -Count 2 -TimeToLive 2 $_ | Out-Null
if($?)
{
RoboCopy /Log:"L:\$folder\$_.log" $source \\$_\c$\tools
RoboCopy /Log+:"L:\$folder\$folder-MovementLogs.log" $source \\$_\c$\tools
Start-Process -Wait "P:\psexec.exe" -ArgumentList "\\$_ -d -e -h -s cmd /c reg import C:\tools\dump.reg"
# Copy-Item -LiteralPath Y:\* -Destination \\$_\c$\tools
$listBox.Items.Add($_)
}
}
import os
os.system("powershell.exe [Get-ItemProperty
HKLM:\\Software\\Wow6432Node\\Microsoft\\\Windows\\CurrentVersion\\Uninstall\\*| Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table –AutoSize > D:\\application whitelisting\\InstalledProgramsPS.txt ]")
this is my code. I want to display the list of software installed in the system.
but i am getting error like
Select-Object is not recognized as an external or internal command.
when i execute the same command using powershell, it is working fine.
can anyone please help?
thanks in advance.
The reason is that Powershell's command parameter is not properly constructed. os.system() call will star a CMD session, and Select-Object is not recognized as an external or internal command is an error message from CMD.
Let's see what CMD does. First it will run Powershell and pass some arguments. Note the triple backslash, which is an error by itself and needs to be fixed.
powershell.exe [Get-ItemProperty HKLM:\\Software\\Wow6432Node\\Microsoft\\\Windows\\CurrentVersion\\Uninstall\\*
| Select-Object DisplayName, DisplayVersion, Publisher, InstallDate
Now, the first thing is that Powershell is invoked and (wrongly) paramerized Get-ItemProperty is passed. Because the pipe char | is used in CMD as well, it is interpreted as a command for CMD. Thus CMD tries to pipe the first command's output to Select-Object, but there isn't such a command in CMD. Thus the error.
To fix the issue, use -command "<commands>" to pass commands to Powershell. The double quotes " are used to create a single string that CMD passes to Powershell as an argument.
powershell.exe -command "Get-ItemProperty HKLM:\\Software\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\*| Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table -AutoSize > D:\\application whitelisting\\InstalledProgramsPS.txt"
The site im working on got 3 individual sites running on the IIS.
When I make changes to on particular library I need to restart the site using it. The way I do that now is by manually rightclicking the IIS Express icon in the system tray, and then clicking 'Stop site', and after that I execute the debugging..
I would like to make that part automatic, so when ever i start debugging it will stop that particular site.
If I don't stop it, then it will just reuse the current running site, but if I stop it, then it will restart it..
Is it event posible? I know how to find the PID, but I don't get the name of the site behind the PID..
I put together this script in PowerShell:
$site = 'Webapplication' # replace this by your site name (not case sensitive)
$process = Get-CimInstance Win32_Process -Filter "Name = 'iisexpress.exe'" | ? {$_.CommandLine -like "*/site:`"$site`"*" }
if($process -ne $null)
{
Write-Host "Trying to stop $($process.CommandLine)"
Stop-Process -Id $process.ProcessId
Start-Sleep -Seconds 1 # Wait 1 second for good measure
Write-Host "Process was stopped"
} else
{
Write-Host "Website was not running"
}
Modify the first line to replace the site name with yours. Save this
file as stopiis.ps1 on your project folder (not the solution folder).
Now, on Solution Explorer, right-click and choose properties
On the left side, choose Build Events
Put this on 'Pre-Build event command line' so it will run before compiling:
echo powershell -File "$(ProjectDir)stopiis.ps1"
powershell -File "$(ProjectDir)stopiis.ps1"
Note: you do not need to run Visual Studio in Administrative mode because IISExpress.exe run under your account
Does anyone know how to hide output from command Select-AzureRmSubscription inside azure workbook which runs as powershell workflow
Thanks
You can use Out-Null. Works for any PowerShell cmdlet.
Select-AzureRmSubscription | Out-null
The Out-Null cmdlet sends its output to NULL, in effect, removing it
from the pipeline and preventing the output to be displayed at the
screen.
https://msdn.microsoft.com/en-us/powershell/reference/5.1/microsoft.powershell.core/out-null
Select-AzSubscription -SubscriptionId $s.Id | Out-Null + ~~~~~~~~ Cannot call the 'Out-Null' command. Other commands from this module have been packaged as workflow activities, but this command was specifically excluded. This is likely because the command requires an interactive Windows PowerShell session, or has behavior not suited for workflows. To run this command anyway, place it within an inline-script (InlineScript { Out-Null }) where it will be invoked in isolation
I've set up an NMS system on a machine running Ubuntu that responds to various UPS events by calling a Perl script to go through all of our VMWare hosts and suspend all of the VMs. VMWare was smart and provided a set of Perl modules which made this relatively easy. We also have three Hyper-V hosts, however, and I can't seem to find a way to control them that isn't specific to some Microsoft technology (e.g. a PowerShell script).
I'm hoping somebody could suggest a way to control the Hyper-V hosts from a linux box. I'd rather it didn't involve using Wine, but I'm willing to go that route if there's nothing else that will work.
I found an ugly way to do it, but at least it doesn't require anything to be installed or configured on the VM host.
First I got a utility called winexe, which lets you open a terminal connection to a windows machine.
Then I wrote a long an ugly Perl script to pipe some PowerShell code to the machine to suspend any running machines:
sub hv_suspend_host {
my $host = $_[0];
my $code = <<'END';
echo '===BEGIN'
$query = "SELECT * FROM Msvm_ComputerSystem WHERE EnabledState != 3 AND EnabledState != 32769" #Exclude off and saved VMs
$VMs = get-wmiobject -query $query -namespace "root\virtualization" -computername "."
foreach ($VM in $VMs) {
if ($VM.name -ne $VM.ElementName) { # Exclude the host itself
if ($VM.RequestStateChange(32769).ReturnValue -eq 4096) { # Put the VM in a saved state
# It worked, log success
} else {
# It didn't, log failure
}
}
}
echo '===END'
exit
END
my $recv;
run(["winexe", '-U', "DOMAIN/$win_user%$win_pass", '--interactive=0', "//$host", 'powershell -command -'], \$code, \$recv);
$recv =~ tr/\r//d; # Convert to UNIX line endings
$recv =~ /===BEGIN\n(.+)===END/s; # Now recv contains anything you logged
}
You might have to mess with this a bit to get it to work. I had to hack out some of the implementation-specific things, but I left in part of the output capturing code. This requires global variables named $win_user and $win_pass containing administrator account login info for the target VM host. It also requires that you use IPC::Run.
Hyper-V can be managed remotely using the WMI interfaces. There is a WMI Client for Linux, which should allow you to make the relevant API calls to manage Hyper-V. I have not had to do this myself, but the specific WMI calls are available at Microsoft: https://msdn.microsoft.com/en-us/library/hh850319%28v=vs.85%29.aspx
