【问题描述】：
我刚刚为 Python 2.7.8 安装了 pywinauto-0.4.2（在 Windows 7 64 位机器上）。我正在尝试在pywinauto
上引用的示例程序SaveFromFirefox.py的源代码（在上面的URL中给出）是：
from pywinauto.application import Application
import sys
import time
import os.path
if len(sys.argv) < 2:
print "please specify a web address to download"
sys.exit()
web_addresss = sys.argv[1]
if len(sys.argv) > 2:
outputfilename = sys.argv[2]
else:
outputfilename = web_addresss
outputfilename = outputfilename.replace('/', '')
outputfilename = outputfilename.replace('\\', '')
outputfilename = outputfilename.replace(':', '')
# start IE with a start URL of what was passed in
app = Application().start_(
r"c:\program files\Mozilla Firefox\Firefox.exe %s"% web_addresss)
# some pages are slow to open - so wait some seconds
time.sleep(4)
# mozilla is one of thos applications that use existing windows
# if they exist (at least on my machine!)
# so if we cannot find any window for that process
# - find the actual process
# - connect to it
if app.windows_():
mozilla = app.window_(title_re = ".*Mozilla Firefox")
else:
app = Application().connect_(title_re = ".*Mozilla Firefox")
mozilla = app.window_(title_re = ".*Mozilla Firefox")
# ie doesn't define it's menus as Menu's but actually as a toolbar!
print "No Menu's in FireFox:", mozilla.MenuItems()
# File -> Save As
mozilla.TypeKeys("%FA")
#ie.Toolbar3.PressButton("File")
app.SaveAs.FileNameEdit.SetEditText(outputfilename)
app.SaveAs.Save.CloseClick()
# if asked to overwrite say yes
if app.SaveAs.Yes.Exists():
app.SaveAs.Yes.CloseClick()
print "saved:", outputfilename
# File close tab or close
#(Firefox makes it easy for us having the same shortcut for both!
mozilla.TypeKeys("%FC")
当我尝试在命令提示符下执行文件时，它会打开 firefox 浏览器，然后打开“另存为”对话框，但没有按“保存”按钮。
相反，它给出了以下错误消息：
C:\Users\arun_m\Desktop>python2 SaveFromFirefox.py www.google.com
No Menu's in FireFox: []

出了什么问题？
【问题讨论】：
-
可能 Firefox 在编写该示例后发生了变化，
Save对话框不再有名为FileNameEdit的字段。您需要阅读 PyWinAuto 文档以了解如何为该字段找到正确的名称。 -
我目前使用的是 Firefox 34 浏览器
-
当然，该示例自 2013 年 3 月以来一直没有更新，当时 Firefox 的版本为 17 左右，因此该示例已过时并非不可信。同样，您需要阅读文档，其中将解释如何为您想要的字段找到正确的名称。 （然后针对 pywinauto 提交错误以修复示例。）
-
提示：请注意，错误消息向您显示了它搜索
'FileNameEdit'的控件名称列表。查看那些看起来可能是文件名编辑框的那些，并查看每个在设置文本时的作用。 -
感谢 abarnert，我将阅读“pywinauto”文档以了解其根源。
