If the remote is a wedge (the driver simulates a keyboard), just write a short piece of code to see which keys produce what codes:
VB Code:
  1. Private Sub Form_Activate()

  2. Me.KeyPreview = True

  3. End Sub

  4.  
  5. Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)

  6. Debug.Print KeyCode & " in KeyDown"

  7. End Sub

  8.  
  9. Private Sub Form_KeyPress(KeyAscii As Integer)

  10. Debug.Print KeyAscii & " in KeyPress"

  11. End Sub
Run the program, press keys and watch the Immediate window.

If the remorte isn't a wedge, you'll have to get the specs on the remote to see how to read the button presses, then do pretty much the same thing - debug.print the inputs you get.

BTW, arrow keys, Pg (up and down) keys, etc. (non-printing keys) don't trigger the KeyPress event since they don't produce ASCII codes, they trigger the KeyDown event and produce keycodes.
