Question

您好我无法在我的桌面应用程序中使用“print_control_identifiers（）”。我正在使用a）Python 3.5.3（32位，因为我的应用程序我自动化是32位） b）Pywinauto 0.6.2。我的简单代码如下：

`from pywinauto import Application
app = Application(backend="uia")    
app = Application().start(r"C:\Program Files (x86)\Trane\TRACE 3D  Plus\TRACE™ 3D Plus.exe")  
app['TRACE™ 3D Plus'].print_control_identifiers()`

当我运行上面的命令时，我在命令提示符下得到以下内容：

Traceback (most recent call last):
File "D:\Python\lib\site-packages\pywinauto\application.py", line 243, in   __re
solve_control
criteria)
File "D:\Python\lib\site-packages\pywinauto\timings.py", line 424, in     wait_until_passes
raise err
pywinauto.timings.TimeoutError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "inspect.py", line 4, in <module>
app['TRACE\u2122 3D Plus'].print_control_identifiers()
File "D:\Python\lib\site-packages\pywinauto\application.py", line 573, in  prin

elements = find_elements(**kwargs)
File "D:\Python\lib\site-packages\pywinauto\findwindows.py", line 294, in find

elements = findbestmatch.find_best_control_matches(best_match, wrapped_elems
)

nd_best_control_matches
raise MatchError(items = name_control_map.keys(), tofind = search_text)
pywinauto.findbestmatch.MatchError: Could not find 'TRACE\u2122 3D Plus' in   'dic
t_keys([])'

有谁能告诉我问题是什么以及我可以做些什么来解决它？

提前致谢！

替换这些命令

app = Application(backend="uia")    
app = Application().start(r"C:\Program Files (x86)\Trane\TRACE 3D  Plus\TRACE™ 3D Plus.exe")

这一个：

app = Application(backend="uia").start(r'"C:\Program Files (x86)\Trane\TRACE 3D  Plus\TRACE™ 3D Plus.exe"')

因为如果不使用任何参数，则使用默认app重新创建backend="win32"对象。如果很难理解，我建议先学习Python课程。这里需要基本的Python编程技能来理解正在发生的事情。
