Converting a hardcoded procedure to a universal library function?

[dmtelf]

I'm an Access newbie, and would like to make a password entry/validation private subroutine into a re-usable library function but am unsure of the best way to do it.

I have two buttons on a menu form.

btnMaintenance (default state: visible,disabled)
btnEnableMaintenance (default state: visible, enabled)

When the user clicks on btnEnableMaintenance, a form is opened and the user is prompted to enter a password.

If the password is valid, then btnMaintenance is enabled.

After three failed attempts, the password entry form window will close and btnMaintenance remains disabled.

At the moment, the name of the controls and valid password are hardcoded into Password_AfterUpdate()

Ideally, I'd use the new password function with three parameters, like this:

EnableButton(ButtonNameToEnable,ButtonEnable,Password)

where:

1) ButtonNameToEnable is the name of the button to enable (initial state is disabled)
2) ButtonEnable is the name of the button which has to be clicked on to enable ButtonNameToEnable
3) Password is the valid password required to enable ButtonNameToEnable

Any suggestions or constructive criticism gratefully welcomed!

Thanks!
