autocompletition?

Hi, I am planning on starting a simple "notepad" like text editor, and was thinking on how to implement autocompletition. So for example, if user type ca, a small popup would show:

can
canada
car
carrot
etc..

I guess a dictionary would be needed, but how to make comparisson to possibilities? Anyone has experience in this sort of things?

Thanks in advance for any ideas.

Maybe this?

partofword$=Input("")
Global dirword$="canada"
find$=partofword$
location=Instr(dirword$,find$)
If location=1 Then
	Print dirword$
Else
EndIf

That won't work... Input stops the program.

Hey, thanks for your thoughts, I will make a temporal variable to count chars and get rid of spaces, before putting them to screen, so hopefully something like Yo! Wazzup? posted will do the trick.

Thanks.

Mabye this helps for a text field, you cn yank the meat out of the code and adapt for your own needs:

I think you need a list of words that is sorted alphabetically.
You can compare strings as if they were integers:

If "Ambient" < "Zelda" then print "A is before Z"

You could store all the words in a Type and search through them while the user is typing.
I would add all typed characters to a temp. string, that is reset whenever the user presses space. With Lower$/Upper$ you can make a string either lowercase or uppercase:

x$ = Upper$(x$)

This makes it easier to compare the input to the wordlist.

Then, I would read all the words into a type, and use First and After to search through the list.

If inputword$ > currentitem\word$ then currentitem = After currentitem

I don't know if you have a wordlist? Diablos posted one here a while ago: http://socoder.net/index.php?topic=439

Hey, thanks to all!! Indeed great ideas. b32 thanks, didn´t knew strings could be compared like that. I do have a list of words, but thanks a lot! Yahfree, I will look more closely and look at your code, seems wome parts will be quite handy.

I will be out of town for a while, hopefully back in a week with a working project. Thanks again, if stuck will come back again.

Cheers.
