Your code wetted my apitite to re-visit an old project that has been
on the back burner for a couple years now.
I have a larger word list now (thanks to Moby) that contains 350k+
records. (my old one had 175k+)
It also contains characters other than A-Za-z and I would like to use
these also.
Note: VB is just a hobby of mine so I'm no pro at it.
Questions:
*
ReDim myWords(676 To 18278)
Can you explain why you used the OddBall dim's here?
Will all words in my list equate with in this range?
*
Function GetValue:
How can I expand this to use other characters besides just A-Za-z?
*
I'm using the RichText control because the List control blows its cool
somewhere in the 's' range even with my old list ;( and it really
takes a lot of time to load so I need some help on how to read the
file X number of records before and after the word. The word list is
just a sequential file using vbCRLF delimiters.
*
Would there be a way to store the information in the collection to a
file so it wouldn't have to be re-built each time?
*
Hope this makes sense to you...
Wow!! I have others but they can wait or they'll get answered in the
process... LOL
Any and All Help is Appreciated..
