NameError: global name 'windll' is not defined

Well it almost looks like your spacing is off.

Be sure to use EITHER a tab or 4 spaces for each indent.

This can cause scope issues which can produce unexpected results.

Try this code and upload the output please:

class master_main(threading.Thread):
    ES_SYSTEM_REQUIRED  = 0x00000001
    ES_DISPLAY_REQUIRED = 0x00000002
    ES_CONTINUOUS = 0x80000000

    def run(self):
    time.sleep(20)
    kernel32  = windll.LoadLibrary("Kernel32.dll")
    kernel32.SetThreadExecutionState(c_int(ES_SYSTEM_REQUIRED|ES_CONTINUOUS|ES_DISPLAY_REQUIRED))
    print "hi"	    
master_main().start()

Select allOpen in new window

Sorry i messed up the spacing as well:

hopefully this uploads proper

class master_main(threading.Thread):
    ES_SYSTEM_REQUIRED  = 0x00000001
    ES_DISPLAY_REQUIRED = 0x00000002
    ES_CONTINUOUS = 0x80000000

    def run(self):
        time.sleep(20)
        kernel32  = windll.LoadLibrary("Kernel32.dll")
        kernel32.SetThreadExecutionState(c_int(ES_SYSTEM_REQUIRED|ES_CONTINUOUS|ES_DISPLAY_REQUIRED))
    print "hi"	    
master_main().start()

Select allOpen in new window

alright yea, just add 4 additional spaces before print "hi" and i think your code will work

Ran it and I got this error ?

Can you upload the latest version of the code you are using?

oh duh, oops

here try this:

from ctypes import *
import os
import time
ES_SYSTEM_REQUIRED  = 0x00000001
ES_DISPLAY_REQUIRED = 0x00000002
ES_CONTINUOUS = 0x80000000

class master_main(threading.Thread):
    ES_SYSTEM_REQUIRED  = 0x00000001
    ES_DISPLAY_REQUIRED = 0x00000002
    ES_CONTINUOUS = 0x80000000

    def run(self):
        time.sleep(20)
        kernel32  = windll.LoadLibrary("Kernel32.dll")
        kernel32.SetThreadExecutionState(c_int(ES_SYSTEM_REQUIRED|ES_CONTINUOUS|ES_DISPLAY_REQUIRED))
        print "hi"	    
master_main().start()

Select allOpen in new window

or this to keep it all together: ( i wish EE had a edit option >.<)

class master_main(threading.Thread):
    from ctypes import *
    import os
    import time
    ES_SYSTEM_REQUIRED  = 0x00000001
    ES_DISPLAY_REQUIRED = 0x00000002
    ES_CONTINUOUS = 0x80000000

    def run(self):
        time.sleep(20)
        kernel32  = windll.LoadLibrary("Kernel32.dll")
        kernel32.SetThreadExecutionState(c_int(ES_SYSTEM_REQUIRED|ES_CONTINUOUS|ES_DISPLAY_REQUIRED))
        print "hi"	    
master_main().start()

if my last code fails, the last thing you can try is adding master_main. before the windll call


windll comes from the os library so if you don't include it in your class you won't be able to access the windll.LoadLibrary() function.

Sorry I should have caught that earlier

you mean ?

class master_main(threading.Thread):
  kernel32  = windll.LoadLibrary("Kernel32.dll")

 def run(self):
        time.sleep(20)  kernel32.SetThreadExecutionState(c_int(ES_SYSTEM_REQUIRED|ES_CONTINUOUS|ES_DISPLAY_REQUIRED))
        print "hi"	
 master_main().start()

Im sorry Im relatively new to programming so I don't understand " if you don't include it in your class you won't be able to access the windll.LoadLibrary() function. " means ... I called import os and import ctypes at the very beginning of my program ... so should I include it again ?

No you don't need to call it again, I was basing my answer on the 2nd block of you posted. It looked like when you made the 2nd program you removed the import os lines

Since python uses tabs and spaces to define the body of f unctions, it is EXTREMELY IMPORTANT to be consistent with spacing.


This means, in your latest posted code for example, you must keep the spacing consistent. Notice how in this code the spacing convention is consistent. this makes it much easier to debug, troubleshoot and read

class master_main(threading.Thread):
    kernel32  = windll.LoadLibrary("Kernel32.dll")

def run(self):
    time.sleep(20)  kernel32.SetThreadExecutionState(c_int(ES_SYSTEM_REQUIRED|ES_CONTINUOUS|ES_DISPLAY_REQUIRED))
    print "hi"	

master_main().start()

Basically the way your code works, is it calls native win32 libraries (kernel32). The error you are getting says that in the current scope (scope is similar to the layer that is currently being executed) windll is not defined. This can happen if the library holding windll isn't showing up.

Can you post YOUR ENTIRE file, not just a snippet of code? You said you already imported os, but in your original post i couldn't find it (except in the first example which you said worked fine)

actually windll is from ctypes not os,

fixed the first error and now I have this one th current code

from ctypes import *
class master_main(threading.Thread):
    
    

    ES_SYSTEM_REQUIRED  = 0x00000001
    ES_DISPLAY_REQUIRED = 0x00000002
    ES_CONTINUOUS = 0x80000000

    def run(self):
	
        time.sleep(20)
        kernel32  = windll.LoadLibrary("Kernel32.dll")
        kernel32.SetThreadExecutionState(c_int(ES_SYSTEM_REQUIRED|ES_CONTINUOUS|ES_DISPLAY_REQUIRED))
    print "hi"	    
master_main().start()

thanks for the help

again this is a scope issue.

either declare the variables within the scope ( under def run())

or: pass the variables like this:

kernel32.SetThreadExecutionState(c_int(master_main.ES_SYSTEM_REQUIRED|master_main.ES_CONTINUOUS|master_main.ES_DISPLAY_REQUIRED))

hope this works for you :)

(if it doesn't try including parenthesis () like this:  master_main().ES......  etc)

You are quite welcome :) hopefully you get the other issues fixed with this code too :p

yes you pointed me in the right direction... it was an align of my code issue... thanks so much
