I have a process running, let\'s call it Process1. Process1 creates a new process, Process2, and saves its id.

Answer 1

The solution provided by @user152949, as it was noted in commentaries, skips the first process and doesn't break when "exists" is set to true. Let me provide a fixed version:

#include 
#include 
#include 

bool IsProcessRunning(const TCHAR* const executableName) {
    PROCESSENTRY32 entry;
    entry.dwSize = sizeof(PROCESSENTRY32);

    const auto snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);

    if (!Process32First(snapshot, &entry)) {
        CloseHandle(snapshot);
        return false;
    }

    do {
        if (!_tcsicmp(entry.szExeFile, executableName)) {
            CloseHandle(snapshot);
            return true;
        }
    } while (Process32Next(snapshot, &entry));

    CloseHandle(snapshot);
    return false;
}
