    You can use EnumWindows() or EnumThreadWindows() to enumerate top level windows and GetWindowThreadProcessid() to check if specific window is created by your process (processInfo.dwProceddId)

      The return value of GetWindowThreadProcessId is the thread Id and not the process Id. If you want the process Id, use the second parameter like so.

      DWORD dwProcessId = 0;
      GetWindowThreadProcessId(hwnd, &dwProcessId);
      if (dwProcessId == (DWORD)param)

        I think it is better to send WM_CLOSE to the window instead of calling DestroyWindow().

          I have used createProcess to run a process in a new window using CREATE_NEW_CONSOLE flag, Can any one help to get the handle to the console that i have created so as to close that window. code: CreateProcess(_T("\\windows\\ceplayer.exe"),_T("c:\\folder\\new.wmv"), NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, NULL, &processInfo); Thanks in Advance

          I suspect you've to use EnumThreadWindows [^], passing, as dwThreadId argument, the dwThreadId member of the PROCESS_INFORMATION struct filled by CreateProcess function. It's just a guess: the test is up to you. :)

                Well, since you just want to close the program you could use TerminateProcess(hProcess, 0);

                    A hammer is another option. :)
