yeah this is what i want but i got a problem how i can connect that into the database.

Dim arTemp() As String = {"ComboBox1", "AutoCompleteSource", "AddRange", "Items", "With", "End With"}

i what to load the string from the database.

can you help about that

I think we can do it by looping but how i can do that, any guide for that

ok.. i have solved it..

i have use the northwind database of microsoft here.. i hope you will understand from it.

Please try the Below:

1. Put a combobox on form.
2. now use following code accordingly:

Imports System.Data.SqlClient
Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim strconn As String = "Data Source=.\SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True"
        Dim conn As New SqlConnection(strconn)
        Dim cmd As New SqlCommand("select ContactName from Customers", conn)
        Dim da As New SqlDataAdapter(cmd)

        Dim ds As New DataSet

        da.Fill(ds, "List")

        Dim col As New AutoCompleteStringCollection ' From which our names will come

        Dim i As Integer
        For i = 0 To ds.Tables(0).Rows.Count - 1

'this is the main part 
        ComboBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
        ComboBox1.AutoCompleteCustomSource = col
        ComboBox1.AutoCompleteMode = AutoCompleteMode.Suggest

    End Sub

see the attachment for more info..

by the way what this code does

da.Fill(ds, "List")

the world "List", is it a column from the database or not?

it will fill the Dataset ds with the Table Named "List" with the data returned by the query..

check the values of ds in debugging mode you will understand.

its ok thanks a lot @codeoreder and @sandeepparekh9 for the help
