How to send number 1 using powershell keystroke.

Question

Would you like to: [1] Accept the certificate for this session Please input your selection (The default selection is [1]): 1 I have to enter number one here, how it can be done through power shell script

Answer 1

Read-Host would be the way to do it from the console while using Write-Host/Write-Output to present the option information. You would of course need to check the contents of the variable to see if you got an expected result.

If you're looking for a simple yes/no answer and are OK with popups, use a .NET messagebox:

[System.Windows.Forms.MessageBox]::Show('message', 'titlemessage')

There are tons of overloads for this which include giving you the ability to control the buttons displayed and the icon (warning, error, informational, etc.)

EDIT: This SO post shows how to accomplish SendKeys functionality with both a COM object and a .NET object: How to perform keystroke inside powershell?

$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('title of the application window')
Sleep 1
$wshell.SendKeys(1)

and

add-type -AssemblyName System.Windows.Forms
[System.Windows.Forms.SendKeys]::SendWait(1)

or

add-type -AssemblyName microsoft.VisualBasic
add-type -AssemblyName System.Windows.Forms

[Microsoft.VisualBasic.Interaction]::AppActivate(“Calc”)
[System.Windows.Forms.SendKeys]::SendWait(“1{ADD}1=”)
