Downloading file using IE from python

Question

I\'m trying to download file with Python using IE:

from win32com.client import DispatchWithEvents

class EventHandler(object):
    def OnDownloadBegin(self):
            


        

Answer 1

This works for me as long as the IE dialogs are in the foreground and the downloaded file does not already exist in the "Save As" directory:

import time
import threading
import win32ui, win32gui, win32com, pythoncom, win32con
from win32com.client import Dispatch

class IeThread(threading.Thread):
    def run(self):
        pythoncom.CoInitialize()
        ie = Dispatch("InternetExplorer.Application")
        ie.Visible = 0
        ie.Navigate('http://website/file.xml')

def PushButton(handle, label):
    if win32gui.GetWindowText(handle) == label:
        win32gui.SendMessage(handle, win32con.BM_CLICK, None, None)
        return True

IeThread().start()
time.sleep(3)  # wait until IE is started
wnd = win32ui.GetForegroundWindow()
if wnd.GetWindowText() == "File Download - Security Warning":
    win32gui.EnumChildWindows(wnd.GetSafeHwnd(), PushButton, "&Save");
    time.sleep(1)
    wnd = win32ui.GetForegroundWindow()
if wnd.GetWindowText() == "Save As":
    win32gui.EnumChildWindows(wnd.GetSafeHwnd(), PushButton, "&Save");
