Auto Complete TextBox

I need a autocomplete text box in .net Windows form.I want it to handle multiple words search separated by comma.

Just like tyoing email address..

plz help.

Do you want it to do this with EVERY word in the known dictionairy? Or just specific words.

That will requier checking the string everytime someone presses a Key.

May I ask is this for a Email address? or?

Yes for every word , and its for email address.Please help me with some code snippets.

We don't give code to people who have not tried first.

I would suggest that you create a function under a KeyPress that takes from the current position of the cursor, back to the begining of the string and check all the characters against a list of words.

So you would have to have something set up that checks, abc against a list of words and says yes it could be abcde or abcdefg or abcgjej etc etc
