c++实现创建，销毁，挂起和激活记事本进程

创建记事本进程：

#include <windows.h>
#include <stdio.h>

int main()
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;

    ZeroMemory(&si, sizeof(si));
    si.cb = sizeof(si);
    ZeroMemory(&pi, sizeof(pi));

    if (!CreateProcess("notepad.exe", NULL, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi))
    {
        printf("CreateProcess failed (%d).\n", GetLastError());
        return 1;
    }

    WaitForSingleObject(pi.hProcess, INFINITE);

    CloseHandle(pi.hProcess);
    CloseHandle(pi.hThread);

    return 0;
}

销毁记事本进程：

#include <windows.h>
#include <stdio.h>

int main()
{
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, processId);

    if (hProcess == NULL)
    {
        printf("OpenProcess failed (%d).\n", GetLastError());
        return 1;
    }

    if (!TerminateProcess(hProcess, 0))
    {
        printf("TerminateProcess failed (%d).\n", GetLastError());
        return 1;
    }

    CloseHandle(hProcess);

    return 0;
}

挂起记事本进程：

#include <windows.h>
#include <stdio.h>

int main()
{
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, processId);

    if (hProcess == NULL)
    {
        printf("OpenProcess failed (%d).\n", GetLastError());
        return 1;
    }

    if (!SuspendThread(hProcess))
    {
        printf("SuspendThread failed (%d).\n", GetLastError());
        return 1;
    }

    CloseHandle(hProcess);

    return 0;
}

激活记事本进程：

#include <windows.h>
#include <stdio.h>

int main()
{
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, processId);

    if (hProcess == NULL)
    {
        printf("OpenProcess failed (%d).\n", GetLastError());
        return 1;
    }

    if (ResumeThread(hProcess) == -1)
    {
        printf("ResumeThread failed (%d).\n", GetLastError());
        return 1;
    }

    CloseHandle(hProcess);

    return 0;
}
