How can I check if "Yes" button in MessageBox() was clicked?

MessageBox (NULL, TEXT ("Yes or no?"), TEXT ("Question"), MB_YESNO | MB_DEFBUTTON1);
...

See for example http://msdn.microsoft.com/en-us/library/windows/desktop/ms645505%28v=vs.85%29.aspx

int result=MessageBox (NULL, TEXT ("Yes or no?"), TEXT ("Question"), MB_YESNO | MB_DEFBUTTON1);
switch(result)
{
    case(IDYES):
       //something to do in the yes case
       break;
   case(IDNO):
       //something to do in the no case
       break;
