Start-Sleep -Seconds 5
$edge = (New-Object -COM "Shell.Application").Windows()| ? { $_.Name -like "*Microsoft Edge*" }
while(1) {
Start-Sleep -Seconds 10
try{
$edge.Refresh()
} catch { exit }
}
The code below should work. Consider using the Microsoft Edge Driver if you need to do more advanced automation.
$proc = [System.Diagnostics.Process]::Start("msedge.exe", "https://www.stackoverflow.com") | Get-Process
$wshell = New-Object -ComObject WScript.Shell
while ($true) {
Start-Sleep -Seconds 10
$wshell.AppActivate($proc.Id)
$wshell.SendKeys("{F5}")

Symantec recently changed their download page which moved to broadcom. Since then Invoke-WebRequest cannot grab the http url for the v5i64.exe file.
However the http url can be found when using Developer Tools in the browser looking at the Elements level, inside the body section of the page.
Does anyone have an idea on how this daily-changed url can be extracted with PowerShell?
$webreq = Invoke-WebRequest "https://www.broadcom.com/support/security-center/definitions/download/detail?gid=sep"
$webreq.Links | Select href
Use IE via ComObject
$ie = new-object -ComObject "InternetExplorer.Application"
$ie.visible=$True
while($ie.Busy) { Start-Sleep -Milliseconds 100 }
$IE.navigate2("https://www.broadcom.com/support/security-center/definitions/download/detail?gid=sep")
while ($IE.busy) {
start-sleep -milliseconds 1000 #wait 1 second interval to load page
}
Then find elementy by $ie.Document.IHTMLDocument3_getElementsByTagName("element name")
The following PowerShell script will prompt you to download the links containing the text v5i64.exe and HTTPS. This works on PowerShell 5.1 for Windows. It does not work for PowerShell 6 or 7 (PowerShell Core).
Tested on Windows 10.0.18363.657, Internet Explorer 11.657.18362, PowerShell 5.1.18362.628
$url = "https://www.broadcom.com/support/security-center/definitions/download/detail?gid=sep"
$outfile = "./v5i64.exe"
$ie = New-Object -ComObject "InternetExplorer.Application"
$ie.visible=$True
while($ie.Busy) {
Start-Sleep -Milliseconds 100
}
$ie.navigate2($url)
while($ie.ReadyState -ne 4 -or $ie.Busy) {
Start-Sleep -milliseconds 500
}
$ie.Document.getElementsByTagName("a") | % {
if ($_.ie8_href -like "*v5i64.exe") {
if ($_.ie8_href -like "https://*") {
$len = (Invoke-WebRequest $_.ie8_href -Method Head).Headers.'Content-Length'
Write-Host "File:" $_.ie8_href
Write-Host "Size:" $len
$confirm = Read-Host "Download file? [y/n]"
if ($confirm -eq "y") {
Write-Host "Downloading" $_.ie8_href
Invoke-WebRequest -Uri $_.ie8_href -OutFile $outfile
}
}
}
}
$ie.Stop()
$ie.Quit()
thanks for the proposed solutions. However here is my final code I am using:
$SEP_last_link = ("http://definitions.symantec.com/defs/"+($SEP_last | Select-String release -NotMatch | select -Last 1))
$Symantec_folder = "C:\Download for DVD\Symantec"
$Symantec_filepath = "$Symantec_folder\$SEP_last"
if (!(Test-Path "$Symantec_filepath" -PathType Leaf)) {
Write-Host "`rStart to download Symantec $SEP_last file: $(Get-Date)`r"
$start_time = (Get-Date)
$webclient = New-Object System.Net.WebClient
$WebClient.DownloadFile($SEP_last_link, $Symantec_filepath)
Write-Host "`r$SEP_last file has been downloaded successfully`r" -ForegroundColor Green
$end_time = $(get-date) - $start_time
$total_time = "{0:HH:mm:ss}" -f ([datetime]$end_time.Ticks)
Write-Host "`rTime to download Symantec $SEP_last file: $total_time`r"
} else {
Write-Host "`rSymantec $SEP_last file already exists!`r" -ForegroundColor Yellow
}
Get-ChildItem -Path "$Symantec_Folder\*-v5i64.exe" -Exclude "$SEP_last" -Verbose –Force | Remove-Item
My case happens when I run $IE.quit() already, but internet explorer still exists in the task manager.
if I run the quit function at "quit IE 1" there, the Internet Explorer will close/end (not exits in Task Manager),
but when I run it at "quit IE 2" there, the IE not end (still exist in Task Manager)
if run with $IE.Visible = $true it has no such problem.
Environment: Windows Server 2016, PowerShell v5.1
May I know what may cause this?
May I know after the "confirm page loaded", what happened to $IE? And possibly cause IE not to quit.
Or how I can trace this kind of problem?
I do try to run this without try/catch, but the same thing happens. I try to put $IE = null, but the same, while, the $IE.Quit() description as to force the end of IE, suppose no wonder what is running on the IE. It will end the task.
Here is the PowerShell script:
$looping = 10
timenowhms = (Get-Date -f HH:mm:ss)
try {
$Url = "http://localhost:8080/commandcenter/checking.aspx"
$IE = New-Object -Com InternetExplorer.Application
$IE.Height = 700
$IE.Width = 750
$IE.Top = 10
$IE.Left = 10
$IE.Visible = $false; # can turn on for testing purpose
$IE.Navigate2($url);
$IEPID = [IntPtr]::Zero
[Win32Api]::GetWindowThreadProcessId($IE.HWND, [ref]$IEPID);
# quit IE 1
$IE.Quit();
} catch {
$timenowhms = (Get-Date -f HH:mm:ss);
echo "$td_date $timenowhms Open website failed";
if ((Get-Process -Name "iexplore*" | ? {$_.Id -eq $IEPID} | measure).Count -eq 1) {
Stop-Process -Id $IEPID -force
};
exit 1
}
# confirm page loaded
while ($ie.Busy -eq $true) {
if ($looping -eq 0) {
$timenowhms = (Get-Date -f HH:mm:ss);
echo "$td_date $timenowhms Timeout, page not show";
if ((Get-Process -Name "iexplore*" | ? {$_.Id -eq $IEPID} | measure).Count -eq 1) {
Stop-Process -Id $IEPID -Force
};
exit 1
} else {
Start-Sleep -Milliseconds 2500;
$looping--;
}
}
# quit IE 2
# $IE.Quit();
exit
I have a script which starts a process only after specific service is running.
It's a loop that's trying to Get-Service its status.
I can't find how to limit loop by time.
The part where I'm stuck:
#add Start button
$button_start = New-Object System.Windows.Forms.Button
$button_start.Location = New-Object System.Drawing.Size(25,70)
$button_start.Size = New-Object System.Drawing.Size(240,32)
$button_start.TextAlign = "MiddleCenter"
$button_start.font = New-Object System.Drawing.Font("Segoe UI",14,[System.Drawing.FontStyle]::Regular)
$button_start.BackColor = "seashell"
$button_start.Text = "Start"
$button_start.Add_Click({
#add statement
while ((Get-Service -ComputerName $textBox_IP.text -ServiceName wscsvc).Status -ne "Running") {
# Pause before next check
Start-Sleep -Seconds 1
}
#only then..
Start-Process -FilePath "C:\Users\username\Desktop\software.exe" -verb RunAs -ArgumentList $textBox_IP.text
})
$Form_remoteControl.Controls.Add($button_start)
I've tried internet searching information on network without any success.
Define a time limit and check if the current time exceeds that limit.
$limit = (Get-Date).AddMinutes(5)
while (... -or (Get-Date) -le $limit) {
Start-Sleep -Seconds 1
}
If you want to skip starting the external program when the service still isn't running after that add another check after the loop upon which you return:
if ((Get-Service ...).Status -ne "Running") {
return
}
This is an example how to stop a service and wait until it is stopped or timeout applies.
You can modify to start a service.
Function StopService ($serv)
{
Write-Host "Config service " $serv " ..."
$service = Get-Service $serv -ErrorAction SilentlyContinue
if ($service)
{
if($service.status -eq "running")
{
write-host "Stop service" $serv
Stop-Service $serv -Force
# Wait until service is stopped (max. 1 minute)
$acttime = 0
$waittime = 100
$maxtime = 60000
$TestService = Get-Service $serv
While($TestService | Where-Object {$_.Status -eq 'Running'})
{
Start-Sleep -m $waittime
$acttime += $waittime
if ($acttime -gt $maxtime)
{
write-host "ERROR: Service" $serv " could not be stopped!" -ForegroundColor Red
return $False
}
}
}
else
{
write-host "Service already stopped!" -ForegroundColor Green
return $True
}
}
else
{
write-host "Service not installed" -ForegroundColor Green
return $True
}
}
I recommend you not using any polling While loops (with Start-Sleep cmdlets) in a Windows forms interface. It will stall your interface for important form events as button clicks etc.
Instead, I would anticipate on the Windows.Forms Timer class by creating a timer event and take appropriate checks and actions after a certain time period (e.g. a new Start-Process depending on a service state).
I'm new to Powershell. I need to capture the output from a command-line call in Powershell continuously and preferably send it to another function. My code currently waits until the external program is completely finished. Here's what I've got:
$startInfo = New-Object System.Diagnostics.ProcessStartInfo
$startInfo.FileName = "DataSet.exe"
$startInfo.CreateNoWindow = $true
$startInfo.UseShellExecute = $false
$startInfo.RedirectStandardError = $true
$startInfo.RedirectStandartOutput = $true
$startInfo.Arguments = "1 off"
$process = New-Object System.Diagnostics.Process
$process.StartInfo = $startInfo
$process.Start() | Out-Null
$stdOut = $process.StandardOutput.ReadToEnd()
$stdErr = $process.StandardError.ReadToEnd()
$process.WaitForExit()
process($stdOut)
process($stdErr)
# Do stuff with $process.ExitCode
Here's what I need
...
while (readOutput)
{
process($stdOut)
process($stdErr)
}
...
I would recommend using a background job for this kind of thing, e.g. like this:
$job = Start-Job -ScriptBlock { & "some.exe" }
while ($job.State -eq 'Running') {
Receive-Job $job -OutVariable $outValue -ErrorVariable $errValue
if ($outValue) { Do-SomethingWith $outValue }
ir ($errValue) { Do-OtherWith $errValue }
Start-Sleep -Milliseconds 200
}
$ie = new-object -com internetexplorer.application
$ie.visible=$true
$ie.navigate('https://google.co.in')
while($ie.ReadyState -ne 4)
{
Write-Host "dom is loading"
$ie.ReadyState -eq 4
$ie.ReadyState -eq 3
$ie.ReadyState -eq 2
$ie.ReadyState -eq 1
$ie.ReadyState -eq 0
start-sleep -M 100
}
($ie.Document.Document3_getElementsByTagName('a')|where-object{$_.innerText -eq "मराठी"}).click()
Try to get Admin Access before running script
Use Below Script before running your script. It will Provide you admin access to run your Script
$myWindowsID = [System.Security.Principal.WindowsIdentity]::GetCurrent();
$myWindowsPrincipal = New-Object System.Security.Principal.WindowsPrincipal($myWindowsID);
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator;
if ($myWindowsPrincipal.IsInRole($adminRole))
{
$Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)";
Clear-Host;
}
else {
$newProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";
$newProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"
$newProcess.Verb = "runas";
[System.Diagnostics.Process]::Start($newProcess);
Exit;
}
this should help you :
$ie = new-object -com internetexplorer.application
$ie.visible=$true
$ie.navigate('https://google.co.in')
while($ie.ReadyState -ne 4)
{ Write-Host "dom is loading" waiting
start-sleep -M 100 }
($ie.Document.IHTMLDocument3_getElementsByTagName('a')|where-object{$_.innerText -eq "मराठी"}).click()
note : when you are running the script second time on ie it will not find the tag because language is already changed
