help sending text to windows edit control

[Richard Leahy]

I am trying to write text into a windows edit
control using python. it seems to write to every control i try except
the edit box not sure if this is a security measure or not. here is my
code any help please.



import os,sys,subprocess,time


from subprocess import *


from os import *


from ctypes import *


from ctypes.wintypes import *





PROCESS_ALL_ACCESS =     ( 0x000F0000 | 0x00100000 | 0xFFF )


kernel32 = windll.kernel32


pid      = sys.argv[1]





h_process = kernel32.OpenProcess( PROCESS_ALL_ACCESS, False, int(pid) )





if not h_process:


    print "[*] Couldn't acquire a handle to PID: %s" % pid


    sys.exit(0)





user32 = windll.user32


# parent window


window_handle = windll.user32.FindWindowA(None, "Windows App")








if not window_handle:


    print "[*] cant find window"





# 1 is the control id of the edit box child window


#below line has no effect on the control for some reason??


windll.user32.SetDlgItemTextA(window_handle, 1, "test") 





# 2 is the control id of a button


# this line works and changes the button text? not sure whats going on


windll.user32.SetDlgItemTextA(window_handle, 2, "test")
