Query regarding 'onKeypress' event and key values.

[CHeighlund]

I am working with a program where I would like the user to be able to 'page through' sets of information. I was considering doing this with the onKeypress event for the form, since the information can be gridded out in a rough two-dimensional form; I'd planned to use a string grid for the information itself, and the keypresses would be used to isolate what cell should be looked at. (Assuming a starting screen of [1,1].)

What character values do the directional keys have? I know that the character for enter is #13 (carriage return), but I do not know what characters would map to the up, down, left, and right arrow keys. Would someone please point me in the direction of this information?

You would do better to use KeyDown instead, since KeyPress does not handle function keys. I believe you will want to check for VK_DOWN, VK_UP, VK_LEFT, and VK_RIGHT.
