Keycode for dash/underscore key

[data808]

I am trying to disable the -/_ key. I disabled the subtract key in the numeric pad. Keycode for that is 109. However, the other subtract key near the backspace and + key is still enabled so I need the keycode for this key. Its the key that gives a dash or underscore if you hold shift with it.

That is a hyphen. ASCII code is 45. Underscore is 95.

How did you determine the numeric keypad is 109?

Don't know but found the keycode by trial and error.

187 = =/+ (this will add a record)
189 = -/_ (this will delete a record)
186 = ;/: (this will insert the date)
188 = ,/< (this will insert the time)

These keys are important to disable if you want your database secure. These keys are used with the ctrl button.
