What have you tried? Where are you stuck?

Where is your code? There are "like" operators both in .NET strings and various database SQLs...

Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load

Dim lst As New List(Of String)

Dim MySource As New AutoCompleteStringCollection()
'Manually added some items
lst.Add("apple")
lst.Add("applle")
lst.Add("appple")
lst.Add("appplee")
lst.Add("bear")
lst.Add("pear")

'Records binded to the AutocompleteStringCollection.
MySource.AddRange(lst.ToArray)

TextBox1.AutoCompleteCustomSource = MySource

TextBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend

TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource

End Sub

There is few ways to achieve that.
String.Contains Method[^]
How to: Search Within a String (Visual Basic)[^]

Depending on your needs, you can use special characters, like: *; ?, etc.
If you want to find a in entire string, use:

VB

result = stringVariable Like "*a*"

If you want to find a at the end of string, use:

VB

result = stringVariable Like "*a"

If you want to find a at the beginning of string, use:

VB

result = stringVariable Like "a*"

Please, see:
Like Operator (Visual Basic)[^]
How to: Match a String against a Pattern (Visual Basic)[^]

You can use Regex[^] too.
