auto compelete textbox in win forms vb.net

hello all,

i am making a form inwhich some key word is typed and searched for.

I want that if a key word is typed many times to search for, then it should be saved some where and when first letter is typed next time, the whole word or matching words should start appearing

like:

if three words (master,member,micro) are searched for frequently, then when type 'm' next time, master,member and micro should start appearing just below the textbox, like it happens when we search on Google.

Please write to me soon

thanks
