Sorry if I was not very clear.  What I'm trying to achieve is as the user is
typing in the serial number, I want to be notified of text changes so I
could say enable the next button, or trigger a CA to custom verify the
serial, and then display a check mark indicating that the serial has been
verified.  I already have it so when I click next nothing happens if the
serial hasn't been verified, I was just curious if you could attach yourself
to the dialog to be notified of these messages.

Could you not attach the Custom Action to the 'Next' button.  I think the
actions are performed in
order, so if you had the first one set an 'OK' property, you could then
use this as a condition for
showing the next dialog or popping up a 'bad prog ID' message.  I think I
have something similar
somewhere I could dig out if you need an example.

I'm probably missing something very simple (very new to Windows
Installer), but is there a way to be notified by a dialog somehow when
text changes?  Or some way to subclass a control?  The reason I ask is
that for the MaskEdit control I have a CA that gets called when "Next"
is pressed that sets a "MyProdIDIsGood" whenever the entered serial has
been validated.  The edit control also is disabled whenever that
property is set.  However, this only happens when scrolling to the next
or previous dialogs, and then I go back since it takes place in the
DlgInit.  I just wanted to be able to have this take place whenever the
user enters a valid serial, such as how MS products display a checkbox
icon or something whenever the serial number has been entered
correctly.  Any help would be greatly appreciated.
