    // contains a non-zero value.
    if (box.Show(this) == DialogResult.No)
    {
        // Do something if the user clicks the No button.

Keterangan

Jika ShowCheckBox adalah true, CheckBoxRegistryMeansDoNotShowDialog adalah true, dan nilai registri ada dan berisi nilai bukan nol, kotak pesan pengecualian tidak ditampilkan dan ExceptionMessageBox mengembalikan DefaultDialogResult ketika Show dipanggil.

Properti ini biasanya true ketika teks kotak centang adalah "Jangan tampilkan pesan ini lagi" atau pesan serupa.
