Hi All,

I am developing an xml editor, inwhich I want to include text
auto-completion.
When I finish entering start element (ie.<Hello>) on rich text box,
the end element (ie.</Hello>) should be entered automatically and also
the cursor is automatically positioned in between the start element
and end element(ie.<Hello>|</Hello>). How should I do this using C#
for Windows environment?

Thanx in advance.

Having done this in the past I'll tell you how...

You need a decent BTree collection implementation which can be a bought in
third-party or home-grown one. To be honest writing one yourself is a pain,
I bought BTree Gold.

Then, as you type, trap the textbox change event and feed the first n
characters into the btree. It will give you back an array of all words that
begin with that character sequence.

I did a medical dictionary lookup for a company that needed to search
100,000+ words and phrases. the search was as fast as I could type so it was
a great result.

HTH
