Printscreen keystroke script . ^{PRTSC} not doing anything – Photoshop

I am trying to create a batch script which puts a screenshot on the clipboard for me to save in another application.

I am using the "^{PRTSC}" and have copied code from another posting here (I would ask/comment there but the listing is closed and I do not have enough points to post there.)

When I run the following line line I get no errors:

powershell -c "$wshell = New-Object -ComObject wscript.shell; $wshell.SendKeys("%{PRTSC}")

But when I create a new document in Photoshop and select Paste ctrl+v, nothing is pasted from the clipboard.

Clearly the code is not putting a screenshot in the clipboard.

( I do not want to use Navcmd )

    Here is an old batch script that use a module in VB.net and save a screenshot as jpeg image with system date:

    As far as I know, windows keyboard supports two shortcuts to capture the screen:

    • PrtScn Captures the entire desktop
    • Alt+PrtScn Captures the active window.

    Per the title and your description, ^{PRTSC} should act as if it’s pressing Ctrl+PrtScn, which will perform the same action as PrtScn.

    Assuming you just want to capture the active window, running the following command from a batch file will work:

    powershell -c "Add-Type -AssemblyName System.Windows.Forms; [System.Windows.Forms.SendKeys]::SendWait('%%{PRTSC}')"

    There are a few differences:

    • Using the SendWait implementation from .NET. The COM SendKeys implementation has some issues, notably around how it reacts to console windows and special keys.
    • I’m using single quotes to quote the string inside the command, otherwise the double quote will end the quoted string being sent to PowerShell.
    • Using % to simulate the Alt key, and more, since it’s in a batch file, escaping the % with %%.
