win32 screen captures

[Robin Becker]

I saw earlier that someone had a sendkeys in python using wsh scripting
(via win32com). I would like to do screen capture, but there seems to be
an explicit ban on {PRTSC}.

Has anyone managed to use PIL and win32com to do screen captures?


Also the sendkeys command and control is un-robust. Is there a native
win32com way to do this and perhaps wait on the windows/events I
initiate before doing the capture?


import win32api
import win32com.client

def sendkeys(k,app,delay=100):
        '''
        Note You can't use SendKeys to send keystrokes to an application that is not designed to run in Microsoft Windows.
        Sendkeys also can't send the PRINT SCREEN key {PRTSC} to any application. 
        '''
        win32api.Sleep(delay)
        return app.SendKeys(k)

if __name__=='__main__':
        import sys
        shell = win32com.client.Dispatch("WScript.Shell")
        shell.Run("Acrobat")
        sk = lambda k, app=shell,delay=100: sendkeys(k,app,delay=delay)
        win32api.Sleep(500)
        shell.AppActivate("Adobe Acrobat")
        win32api.Sleep(500)

        sk('%fo',delay=500)
        sk(sys.argv[1]+'{ENTER}',delay=500)
        sk('%{PRTSC}',delay=1000)
