What is the best way to display one value and store another on .net comboboxes?
I can't seem to find an easy to use, .net native way to get Comboboxes on .net winforms to display one value and return another based on the selection without creating my own helper class, with the knowledge that winforms is going to display the ToString method on the object that you put in it.

What, if any, printable character did a user type based on the values in a given System.Windows.Forms.KeyEventArgs?
As a workaround for a problem, I think I have to handle KeyDown events to get the printable character the user actually typed. KeyDown supplies me with a KeyEventArgs object with the properities KeyCode, KeyData, KeyValue, Modifiers, Alt, Shift, Control. My first attempt was just to consider the KeyCode to be the ascii code, but KeyCod...
