Re: CreateProcess() it's extermely slow

hi all,
I want to create a program that opens all the type of documents
registered on a machine, and the easiest way to do that is to run the
CMD.EXE's START command.
I notice that if my application has no Window, the CreateProcess is
extremely fast as I want. But if I previously create a window (via
CreateWindow()) to run the same command (c:\windows
\system32\cmd.exe /
c start www.google.com) it takes something like 30 secs and it is
hard
to tell what the system is doing.

    // Start the child process.
    if( !CreateProcess( NULL, // No module name (use command line).
        argv[1], // Command line.
        NULL, // Process handle not inheritable.
        NULL, // Thread handle not inheritable.
        FALSE, // Set handle inheritance to FALSE.
        0, // No creation flags.
        NULL, // Use parent's environment block.
        NULL, // Use parent's starting directory.
        &si, // Pointer to STARTUPINFO structure.
        &pi ) // Pointer to PROCESS_INFORMATION
structure.
    )
    {
        result=GetLastError();
/* ZeroMemory( &lpszMess, sizeof(lpszMess) ); */
                sprintf(lpszMess,"Errore:%d", result);
                MessageBox(NULL,lpszMess, NULL, MB_OK);
        return result;
    }

    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );

    // Close process and thread handles.
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
        if ( argc==3 && !strcmp(argv[2], "debug"))
                MessageBox(NULL,"Finito", NULL, MB_OK);

        return 0;
