How can I find out how many characters fit in the remaining space in a TextBox?

Question

I have a text box with a certain width and a string. How do I know how many characters fit from the end of the string until the end of the line?

Answer 1

you can't, first because different characters take up different widths and second because text is rendered differently on different platforms.

Answer 2

The number of characters that will fit depends on the font and what characters they are. If you know what characters you will use, or are using a fixed-width font, you can use Graphics.MeasureString().
