使用进程名称获取另一个程序窗口的标题

在介绍所有内容之前，我想指出一下SO：通过ctypes从Python调用的C函数返回错误值（@CristiFati的回答）。在使用_CTypes_ 之前， 请先 阅读它。

这是我在评论中的意思：

import win32guidef enumWindowsProc(hwnd, lParam):    print win32gui.GetWindowText(hwnd)win32gui.EnumWindows(enumWindowsProc, 0)

在下面，我粘贴了整个内容…由于我搞砸了安全设置（这是 XP !!!），因此无法在我现在使用的 PC 上正常工作，并且一堆 访问被拒绝（错误）代码： 5 ）错误，但是在这里。 __

pre00.py ：

不用说：

• 为了使此代码起作用，您需要以特权用户（ Administrator ）运行它；至少需要 SeDebugPrivilege （[MS.Docs]：Privilege Constants）。
• 当进程以 32/64位 模式运行时（执行此代码的 python 进程以及该代码枚举的目标进程），可能会感到惊讶。

• 更换了所有 的ctypes 通过电话 PyWin32 者
• 改进算法
• 修复了先前版本中的错误
