I'd like to create a "browse" window.  This window would act
exactly like a multiline edit control, with two exceptions:
   1. The user could not modify or select any data
   2. The program could add text to the window (with an edit control,
      it appears that the program can only SET the text, and I'd like
      to add a line, add another line, etc.)

I THINK that this suggests I should subclass multiline edit.
In my subclass function, I could pretty easily handle #1 above, by ignoring
the messages that would modify or select the data.  I don't see how to
do #2; how can I add text?  The only way I can think of is to
get all the text from the edit control into a buffer, concatenate
my text onto the end, and then set the text of the edit control.
Is there a better way?
