So I made two console applications separately one named "The Periodic Table" and the other named "Search Element".
The "Search Element" application is the sub part of "The Periodic Table" application. So it means that I want to call "Search Element" from "The Periodic Table" and I want to end all the instances of "Search Element" when the user closes "The Periodic Table".
So how can I do that??

Here is the sample. Note that there is no error or Ctrl+C handling.
int main() { std::vector < PROCESS_INFORMATION > processes_; while (true) { char command_; std::cout << "Press n for new Notepad instance or x for Exit\n"; std::cin >> command_; switch(command_) { case 'n': case 'N': { std::array<TCHAR, 1024> args_ = {}; PROCESS_INFORMATION info_; STARTUPINFO details_ = {}; details_.cb = sizeof(details_); if(CreateProcess(_T("C:\\Windows\\System32\\Notepad.exe"), args_.data(), NULL, NULL, false, 0, NULL, NULL, &details_, &info_)) processes_.push_back(info_); break; } case 'x': case 'X': { for(auto process_ : processes_) { TerminateProcess(process_.hProcess, 0); CloseHandle(process_.hProcess); CloseHandle(process_.hThread); } processes_.resize(0); } default: { std::cin.clear(); std::cout << "Invalid input"; std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n'); } } } }
