Visual Basic Combobox

I have created a combobox on my form.  I have added four items to the combobox.  Once one of these items in the combobox is clicked, I need a textbox to be populated with a price associated with the item in the combobox.  I am using a select case statement in the combobox click event to accomplish this.  Is this the right direction to go?  How can I get the selected item from the combobox to send a message to the textbox once it is clicked?
Thanks

Yes, you are thinking along the correct lines.  

There are two ways to do this.  If you are using a database, tie the textbox to a datasource or create a recordset in code.  The SQL will look something like

ADODC1.RecordSource = "SELECT price FROM MyData WHERE MyData.ItemName = '" & Me.ComboBox.Text & "'"
ADODC1.Refresh

If it hardcoded in code
SELECT CASE Me.ComboBox.Text
Case "ITEM1" Me.textBoxPrice= 3.50
Case "ITEM2" Me.textBoxPrice = 4.50
' One case for each item
.
.
.
end select

good luck

Personally, if there's no database in use, I'd load all prices into a module-level array variable.  On click in the combobox, take the price from the array and place into the textbox (although a label might be better if the price cannot be changed.)

Private m_curPriceArray() as Currency

Private Sub Combo1_Click()
  Text1.Text = m_curPriceArray(Combo1.ListIndex)
End Sub

Private Sub Form_Load()
  ' fill combo with items, and array with prices
  ReDim m_curPriceArray(3)

  Combo1.AddItem "Item1"
  m_curPriceArray(0) = 17.34

  Combo1.AddItem "Item2"
  m_curPriceArray(1) = 23.95

  Combo1.AddItem "Item3"
  m_curPriceArray(2) = 19.45

  Combo1.AddItem "Item4"
  m_curPriceArray(3) = 9.95
end sub

Or if U has DBase in use (storing Items, Prices)
U can make use of   itemdata Property of combobox to hold Unique ID of item record
