How to detect win32 process creation/termination in c++

by

WMI is great and it works with process names too. Although if you need to track process termination the more lightweight and easier way is the following:

VOID CALLBACK WaitOrTimerCallback(
    _In_  PVOID lpParameter,
    _In_  BOOLEAN TimerOrWaitFired
    )
{
    MessageBox(0, L"The process has exited.", L"INFO", MB_OK);
    return;
}

DWORD dwProcessID = 1234;
HANDLE hProcHandle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessID);

HANDLE hNewHandle;
RegisterWaitForSingleObject(&hNewHandle, hProcHandle , WaitOrTimerCallback, NULL, INFINITE, WT_EXECUTEONLYONCE);

This code will call WaitOrTimerCallback once the process terminated.
