VC 查找进程，关闭进程

转自： http://blog.sina.com.cn/s/blog_55205e230100gwq6.html

以上三个函数使用前先添加头文件

#include "Psapi.h"

然后工程属性里面添加相关类库

SETTING->LINK 里添加Psapi.lib

//
// FindProcess
// 这个函数唯一的参数是你指定的进程名，如:你的目标进程
// 是 "Notepad.exe",返回值是该进程的ID，失败返回0
//

DWORD FindProcess(char *strProcessName)
{
    DWORD aProcesses[1024], cbNeeded, cbMNeeded;
    HMODULE hMods[1024];
    HANDLE hProcess;
    char szProcessName[MAX_PATH];

    if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )  return 0;
    for(int i=0; i< (int) (cbNeeded / sizeof(DWORD)); i++)
    {
        //_tprintf(_T("%d\t"), aProcesses[i]);
        hProcess = OpenProcess(  PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, aProcesses[i]);
        EnumProcessModules(hProcess, hMods, sizeof(hMods), &cbMNeeded);
        GetModuleFileNameEx( hProcess, hMods[0], szProcessName,sizeof(szProcessName));
      
        if(strstr(szProcessName, strProcessName))
        {
            //_tprintf(_T("%s;"), szProcessName);
            return(aProcesses[i]);
        }
        //_tprintf(_T("\n"));
    }

    return 0;
}

//
// Function: ErrorForce
// 此函数中用上面的 FindProcess 函数获得你的目标进程的ID
// 用WIN API OpenPorcess 获得此进程的句柄，再以TerminateProcess
// 强制结束这个进程
//

VOID KillProcess()
{
    // When the all operation fail this function terminate the "winlogon" Process for force exit the system.
    HANDLE hYourTargetProcess = OpenProcess(PROCESS_TERMINATE|PROCESS_QUERY_INFORMATION |   // Required by Alpha
         PROCESS_CREATE_THREAD     |   // For CreateRemoteThread
         PROCESS_VM_OPERATION      |   // For VirtualAllocEx/VirtualFreeEx
         PROCESS_VM_WRITE,             // For WriteProcessMemory
         FALSE, FindProcess("YourTargetProcess.exe"));

    if(hYourTargetProcess == NULL)
    {
        return;
    }

    TerminateProcess(hYourTargetProcess, 0);

    return;
}

//
// GetDebugPriv
// 在 Windows NT/2000/XP 中可能因权限不够导致以上函数失败
// 如以　System 权限运行的系统进程，服务进程
// 用本函数取得　debug 权限即可,Winlogon.exe 都可以终止哦 :)
//

BOOL GetDebugPriv()
{
 HANDLE hToken;
 LUID sedebugnamue;
 TOKEN_PRIVILEGES tkp;

 if ( ! OpenProcessToken( GetCurrentProcess(),
  TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken ) )
    {
  return FALSE;
    }
 

 if ( ! LookupPrivilegue( NULL, SE_DEBUG_NAME, &sedebugnamue ) )
 {
  CloseHandle( hToken );
  return FALSE;
 }

 tkp.PrivilegeCount = 1;
 tkp.Privileges[0].Luid = sedebugnamue;
 tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

 if (!AdjustTokenPrivileges( hToken, FALSE, &tkp, sizeof tkp, NULL, NULL ) )
    {
        CloseHandle( hToken );
        return FALSE;
    }

    return TRUE;
}
