Should OK button be on left or right?

Listing OK first supports the natural reading order in English and other languages that read left-to-right. Many other button sets have a natural progression (say, Yes / No or Previous / Next). You should always list these so that the reading order matches the logical order — in this case, OK / Cancel.

Should cancel go on left or right?

In most languages, people are accustomed to read from left side to right side, so it accords with our speech habits to put ok-key on the left side of cancel-key.

What will happen if you choose OK instead of cancel in this dialog box?

On a dialog box, clicking the 'Ok' button means the user wants the system to act. Clicking the 'Cancel' button means the user wants to go back to the original screen.
