Windows dialog box removal

[SectorUnknown]

I've written a Python script that runs a MS Windows program using popen.
However, at the end of the Windows program, a dialog box appears and
asks for the user to click on OK.

Is there a way to have Python set focus on the dialog box and click OK
so my script can continue?

Does anyone have an example?

I wouldn't be surprised if there's an easier or more correct way to do this,
but if you can reliably know the title of the window then the code below
should work (assuming you have ctypes installed):

from ctypes import *
user32 = windll.user32

EnumWindowsProc = WINFUNCTYPE(c_int, c_int, c_int)

def GetHandles(title, parent=None):
'Returns handles to windows with matching titles'
hwnds = []
def EnumCB(hwnd, lparam, match=title.lower(), hwnds=hwnds):
title = c_buffer(' ' * 256)
user32.GetWindowTextA(hwnd, title, 255)
if title.value.lower() == match:
hwnds.append(hwnd)

if parent is not None:
user32.EnumChildWindows(parent, EnumWindowsProc(EnumCB), 0)
else:
user32.EnumWindows(EnumWindowsProc(EnumCB), 0)
return hwnds

Here's an example of calling it to click the Ok button on any window that has
the title "Downloads properties" (most likely there are 0 or 1 such windows):

for handle in GetHandles('Downloads properties'):
for childHandle in GetHandles('ok', handle):
user32.SendMessageA(childHandle, 0x00F5, 0, 0) # 0x00F5 = BM_CLICK

I've added this example to the ctypes wiki, so it will not be lost. Hope
that's ok ;-)
