Wich key is pressed on the keyboard

Is it possible to know what key on the keyboard that was pressed through any of these syntax in any way in a RichTextBox.

textBox->KeyPress
textBox->KeyUp
textBox->KeyDown

I like to find an if statement that says something like this, though I know this is wrong:

Code:

---

if ( textBox-> KeyPress != BackSpace)
{
//Action;
}
