I’ll explain the buttons and icons now. Buttons are the options available to the victim. Select from the following:. 0 — OK.

1 — OK and Cancel. 2 — Abort, Retry, and Ignore. 3 — Yes, No, and Cancel. 4 — Yes and No. 5 — Retry and Cancel In addition, you can choose the Icon that appears alongside the error messages:.
