Checking results of MessageBox MB_ABORTRETRYIGNORE

I have the following MessageBox:

MessageBox MB_ABORTRETRYIGNORE|MB_ICONEXCLAMATION|MB_DEFBUTTON2

I would like to have a condition that would check which button has been clicked.

How can I do this?

For example:

MessageBox MB_YESNO "Yes?" IDNO no IDYES yes
yes:
no:
