Suppress console when calling “system” in C++

Question

I\'m using the system command in C++ to call some external program, and whenever I use it, a console window opens and closes after the command finishes.

Answer 1

Here's a way to execute commands without a new cmd.exe window. Based on Roland Rabien's answer and MSDN, I've written a working function:

int windows_system(const char *cmd)
{
  PROCESS_INFORMATION p_info;
  STARTUPINFO s_info;
  LPSTR cmdline, programpath;

  memset(&s_info, 0, sizeof(s_info));
  memset(&p_info, 0, sizeof(p_info));
  s_info.cb = sizeof(s_info);

  cmdline     = _tcsdup(TEXT(cmd));
  programpath = _tcsdup(TEXT(cmd));

  if (CreateProcess(programpath, cmdline, NULL, NULL, 0, 0, NULL, NULL, &s_info, &p_info))
  {
    WaitForSingleObject(p_info.hProcess, INFINITE);
    CloseHandle(p_info.hProcess);
    CloseHandle(p_info.hThread);
  }
}

Works on all Windows platforms. Call just like you would system().
