终极结束进程方法API

---

引言

最近在机房里上课的时候，学生的电脑上都安装了相应的学生端软件，而这些软件并没法正常关闭，用任务管理器也无法关闭，下面我说一下如何用Windows API对这类顽固程序进行终结。

福利方法

由于相关方面的规定，这里我只列出相应的操作函数和一些实现原理，具体程序代码我就不贴上了，想深入了解的，可以私信我。

方法一. 消息投递

这里用到的方法就是获取要关闭进程的窗口句柄，然后发送关闭消息到进程的消息队列中，让进程执行关闭消息，这样进程就会以正常的方式自动关闭，而且不会引发内存泄露等问题。（此方法能关闭大部分进程）

涉及API

//API_获得窗口关联进程IDDWORD WINAPI GetWindowThreadProcessId(  _In_      HWND    hWnd,  _Out_opt_ LPDWORD lpdwProcessId);

//API_取进程快照HANDLE WINAPI CreateToolhelp32Snapshot(  _In_ DWORD dwFlags,  _In_ DWORD th32ProcessID);

//API_枚举父窗口BOOL WINAPI EnumWindows(  _In_ WNDENUMPROC lpEnumFunc,  _In_ LPARAM      lParam);

//API_快照中获取进程列表BOOL WINAPI Process32First(  _In_    HANDLE           hSnapshot,  _Inout_ LPPROCESSENTRY32 lppe);

//API_遍历快照中进程列表BOOL WINAPI Process32Next(  _In_  HANDLE           hSnapshot,  _Out_ LPPROCESSENTRY32 lppe);

//API_关闭内核对象BOOL WINAPI CloseHandle(  _In_ HANDLE hObject);

//API_投递消息BOOL WINAPI PostMessageA(  _In_opt_ HWND   hWnd,  _In_     UINT   Msg,  _In_     WPARAM wParam,  _In_     LPARAM lParam);

PostMessageA函数是关闭程序的关键只需要将Msg参数设置为AE_RESACCESS2即可，对应的值为18。此常量来源于lmaudit.h。

方法二. TerminateProcess 干掉进程

说到TerminateProcess 必要说一下ExitProcess，这两个函数都是用于干掉进程的，ExitProcess是用于干掉自身的，TerminateProcess 是用于干掉其它程序的进程的， 所以这里用TerminateProcess 来进行功能制作。
函数原型：

BOOL WINAPI TerminateProcess(  _In_ HANDLE hProcess,  _In_ UINT   uExitCode);

VOID WINAPI ExitProcess(  _In_ UINT uExitCode);

主要步骤就是通过进程名获取窗口句柄，通过窗口句柄获取进程ID，然后通过进程ID获取进程ID的句柄，然后就可以终结了。这里还有一个API就是OpenProcess，通过这OpenProcess获得进程ID对应的句柄。

HANDLE WINAPI OpenProcess(  _In_ DWORD dwDesiredAccess,  _In_ BOOL  bInheritHandle,  _In_ DWORD dwProcessId);

//小例子BOOL KillProcess(DWORD ProcessId) {    HANDLE hProcess = OpenProcess(PROCESS_TERMINATE, FALSE, ProcessId);    if(hProcess == NULL) return FALSE;    if(!TerminateProcess(hProcess, 0)) return FALSE;    return TRUE;}

本人只是抛砖引玉，想研究的可以深入研究，此方面可以用于终止恶意顽固程序进程等。
