我尝试通过长对象的句柄获取Windows窗口标题名称和pids.我的代码有效,但它有问题.当我应该获得10个或更多时,我只获得4个窗口标题.任何人都可以帮助并告诉我如何修复此代码？我认为问题在于我如何转换长对象(我不太了解它们,以及一般的ctypes).

from __future__ import print_function
from ctypes import *

psapi = windll.psapi
titles = []


# get window title from pid
def gwtfp():
    max_array = c_ulong * 4096
    pProcessIds = max_array()
    pBytesReturned = c_ulong()

    psapi.EnumProcesses(byref(pProcessIds),
                        sizeof(pProcessIds),
                        byref(pBytesReturned))

    # get the number of returned processes
    nReturned = pBytesReturned.value/sizeof(c_ulong())
    pidProcessArray = [i for i in pProcessIds][:nReturned]
    print(pidProcessArray)
    #
    EnumWindows = windll.user32.EnumWindows
    EnumWindowsProc = WINFUNCTYPE(c_bool, POINTER(c_int), POINTER(c_int))
    GetWindowText = windll.user32.GetWindowTextW
    GetWindowTextLength = windll.user32.GetWindowTextLengthW
    IsWindowVisible = windll.user32.IsWindowVisible


    for process in pidProcessArray:
        #print("Process PID %d" …

我正在使用 Visual Studio Community 2017 来编写 C++ 代码。当我运行以下代码时，一切正常。

#include "pch.h"
#include<Windows.h>
#include<Psapi.h>
#include <iostream>
#include <conio.h>

int main()
{

    std::cout << "Really!! How do you do it?";
    _getch();
}

#include但是，如果我通过包含psapi.hbefore来更改 s 的顺序Windows.h，编译器就会变得很糟糕并向我抛出 198 个错误，其中令人惊讶的是（也许仅对我来说）包括Identifier "BOOL" is undefined。为什么会发生这种情况？

我试图使用EnumProcessesWin32 (psapi) 提供的函数枚举 Windows 进程。生活很顺利，所以我使用 Rust 而不是 C++。代码如下。

Cargo.toml

[dependencies.windows]
features = [
    "Win32_Foundation",
    "Win32_System_ProcessStatus"
]

主程序.rs

use windows::Win32::System::ProcessStatus::*;
fn main() {
    unsafe{
        let mut cb_needed: u32 = 0;
        let mut a_processes: Vec<u32> = Vec::with_capacity(1024);
        let result: windows::Win32::Foundation::BOOL = EnumProcesses(a_processes.as_mut_ptr(), 1024*4, &mut cb_needed);
        let mut _c_processes: u32 = 0;
        _c_processes = cb_needed / 4;
        println!("{:?}",_c_processes);
        let mut count: u32 = 0;
        while count < _c_processes {
            println!("{:?}",a_processes[count as usize]);
            count += 1;
        }
    }
}

当我调试代码时，变量a_processes显示长度为零。然而，变量 …
