本文提供了在Windows环境下终止指定进程名称或窗口标题的进程的方法，并展示了如何创建新的进程。通过使用如CreateToolhelp32Snapshot、TerminateProcess及CreateProcess等API函数实现进程管理。

//需要头文件

#include<Tlhelp32.h>

int KillProcess(LPCSTR pszProcessName)
{
    int res = 0;

    HANDLE handle; //¶¨ÒåCreateToolhelp32SnapshotÏµÍ³¿ìÕÕ¾ä±ú

    HANDLE handle1; //¶¨ÒåÒª½áÊø½ø³Ì¾ä±ú

    handle = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);//»ñµÃÏµÍ³¿ìÕÕ¾ä±ú

    PROCESSENTRY32 *info; //¶¨ÒåPROCESSENTRY32½á¹¹×ÖÖ¸

    //PROCESSENTRY32 ½á¹¹µÄ dwSize ³ÉÔ±ÉèÖÃ³É sizeof(PROCESSENTRY32)

    info=new PROCESSENTRY32;

    info->dwSize=sizeof(PROCESSENTRY32);

    //µ÷ÓÃÒ»´Î Process32First º¯Êý£¬´Ó¿ìÕÕÖÐ»ñÈ¡½ø³ÌÁÐ±í

    Process32First(handle,info);

    //ÖØ¸´µ÷ÓÃ Process32Next£¬Ö±µ½º¯Êý·µ»Ø FALSE ÎªÖ¹

    do
    {
        info->szExeFile;     //Ö¸Ïò½ø³ÌÃû×Ö

        //strcmp×Ö·û´®±È½Ïº¯ÊýÍ¬Òª½áÊøÏàÍ¬

        if( strcmp(pszProcessName,info->szExeFile) == 0 )
        {
            //PROCESS_TERMINATE±íÊ¾Îª½áÊø²Ù×÷´ò¿ª,FALSE=¿É¼Ì³Ð,info->th32ProcessID=½ø³ÌID

            handle1=OpenProcess(PROCESS_TERMINATE,FALSE,info->th32ProcessID);

            //½áÊø½ø³Ì

            res = TerminateProcess(handle1,0);

        }


    }while(Process32Next(handle,info)!=FALSE);
    CloseHandle(handle);
    return res;
}
int KillProcess2(LPCSTR pszWindowTitle)
{
    HANDLE hProcessHandle;
    ULONG nProcessID;
    HWND TheWindow;

    TheWindow = ::FindWindow( NULL, pszWindowTitle );
    ::GetWindowThreadProcessId(TheWindow, &nProcessID );
    hProcessHandle = ::OpenProcess( PROCESS_TERMINATE, FALSE, nProcessID );
    return ::TerminateProcess( hProcessHandle, 4 );

}
int CreateNewProcess(LPCSTR pszExeName)
{
    PROCESS_INFORMATION piProcInfoGPS;
    STARTUPINFO siStartupInfo;
    SECURITY_ATTRIBUTES saProcess, saThread;
    ZeroMemory( &siStartupInfo, sizeof(siStartupInfo) );
    siStartupInfo.cb = sizeof(siStartupInfo);
    saProcess.nLength = sizeof(saProcess);
    saProcess.lpSecurityDescriptor = NULL;
    saProcess.bInheritHandle = true;
    saThread.nLength = sizeof(saThread);
    saThread.lpSecurityDescriptor = NULL;
    saThread.bInheritHandle = true;
    return ::CreateProcess( NULL
        , (LPTSTR)pszExeName
        , &saProcess
        , &saThread, false,
       CREATE_DEFAULT_ERROR_MODE
       , NULL, NULL
       , &siStartupInfo
       , &piProcInfoGPS
       );
