Hi,
Can someone translate this for me, the most easiest way.
Because I am terrible in math:

        private void SizeLastColumn(ListView lv)
        {
            int x = lvNotes.Width / 15 == 0 ? 1 : lvNotes.Width / 15;
            lvNotes.Columns[0].Width = x * 2;
            lvNotes.Columns[1].Width = x;
            lvNotes.Columns[2].Width = x * 2;
        }

put in x 1 if listview width divided to 15 is zero otherwise put the devision result
resize the columns:
0 -> x by 2
1 -> x
2 -> x by 2

Column 1 will be width 'x', which is 1 unit wide for every 15 of lvNotes.Width, minimum of 1.
Column 0 & 2 will be twice the width of column 1.

What the purpose of the ?-sign. What does that mean?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

its a method to write if else in one row

same as writing...
if(lvNotes.Width / 15 == 0)
{
x=1;
}
else
{
x=lvNotes.Width / 15;
}
