i think i understand what you are trying to do, Your trying to search for each item within the combo box that contains the letters that are typed in to the combo box,

Where abouts are you getting the items from? A database?

If so you could just make a simple sql statement and everytime the textchanged event is launched fire up the sql

another way would be to have a list of your items on the text changed event
clear all the current items out of the combo
start a for loop to go through the list
if the item in that list contains whatever has been typed in so combo1.text
add it to the items of the combo

One more information, textbox and combobox support autocomple feature, look at their property, you might be intersted in combobox with autocomplete source set to listitems, and autocomplete mode to SuggestAppend or Append or anything like that

I have set the AutoCompleteSource and AutoCompleteMode properties of the combox. Now it displays the dropdown list and allows me to
select the item from the list but is not allowing to enter a new item to the combobox text field.

Expand|Select|Wrap|Line Numbers

 Private Sub cbcity_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbcity.TextChanged

        If cbcity.Text <> "" Then

            cbcity.AutoCompleteSource = AutoCompleteSource.ListItems

            cbcity.AutoCompleteMode = AutoCompleteMode.SuggestAppend

        End If

    End Sub

Please tell me where I have made the mistake

Dont use textchanged event, just use those code in the beginning or after binding the data
combobox.DataSource= YouDataSource

and those 2 lines after that
