查找、结束进程

#include <Psapi.h>
#pragma comment(lib, "Psapi.lib")

DWORD FindProcessByName(char *szFindProcessName)
{
    DWORD aProcesses[1024], cbNeeded, cbMneeded;
    HMODULE hMods[1024];
    HANDLE hProcess;
    char szProcessName[MAX_PATH], *pTmp;
    int i;

    if(!EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded))
    {
        return 0;
    }
    strlwr(szFindProcessName);
    for(i=0; i < (int)(cbNeeded/sizeof(DWORD)); 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));
        strlwr(szProcessName);
        if((pTmp = strstr(szProcessName, szFindProcessName)) && *(pTmp-1) == '\\')
        {
            return aProcesses[i];
        }
    }
    return 0;
}


int KillProcessByName(char *strProcessName)
{
    DWORD pid;
    HANDLE hProcess;

    pid = FindProcessByName(strProcessName);
    if(0 == pid)
    {
        return -1;
    }
    hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
    if(NULL == hProcess)
    {
        return -2;
    }
    TerminateProcess(hProcess,0);
    CloseHandle(hProcess);
    return 0;
}

还有另一种写法：

#include <TlHelp32.h>

DWORD FindProcessByName(char *ProcessName)
{
    HANDLE hHandle;
    BOOL Next;
    char szName[MAX_PATH];
    PROCESSENTRY32 p32 = {sizeof(p32)};

    hHandle = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    if(INVALID_HANDLE_VALUE == hHandle)
    {
        MyDebugPrint("CreateToolhelp32Snapshot failed (%lu)\r\n", GetLastError());
        return 0;
    }
    Next = Process32First(hHandle, &p32);

    while (Next) 
    { 
        wsprintf(szName, "%s", p32.szExeFile);
        if (lstrcmpi(szName, ProcessName) == 0)
        {
            return p32.th32ProcessID ;
        }
        Next = Process32Next(hHandle, &p32); 
    } 
    CloseHandle(hHandle);
    return 0;
}
