Creating a simple listbox that will have the same features as a bound datalist box

The purpose of this example is to connect/display database records (using ADO) with a simple
listbox. This is a work around to using bound controls. You will find your apps will run faster

Assumes:You will need to draw a listbox on a form. You will need to create an Access database
and an ODBC DataSource

Dim cn As New ADODB.Connection
Dim rs As New ADODB.Recordset
cn.ConnectionString = "Provider=MSDASQL.1; _
Persist Security Info=False; _
Data Source=DSG_Input"
cn.Open

'SQL Statement to extract all customers from the database

sql = "Select First_Name, Cust_ID from Customer _ Order by First_Name"
Set rs = cn.Execute(sql)

'Populates the listbox**

With List1
Do While Not rs.EOF
.AddItem rs("First_Last")
rs.MoveNext
Loop
End With

'*You now have a listbox containing the records from your database
'*You will create an array that is dynamic to your recordset. This will keep track of
'*the primary key as a boundColumn would in a datalist box. This is for the purpose
'*of relational databases.
'*You will create the array the same size as the listIndex count (number of records in listbox).

rs.movefirst
ReDim array1(List1.ListCount) As String

'*This will now populate the array which is a mirror image as the listbox, but with the primary key.

For i = 0 To List1.ListCount - 1
array1(i) = rs("Cust_ID")
rs.MoveNext
Next i

'*We have now completed the listbox. You can use this listbox the same way as you would a
'*datalist box. The following code will explain how.
'*To access the primary key relating to each record in the list, put the following code in
'*the listbox "Click()" event. This explains how to access the primary key stored in the array.
'*list1.listIndex explains with record in the list was clicked on. You use this to find
'*where in the array the primary key is stored.

Private Sub List1_Click()
Dim Primary_1 as String
Primary_1 = array1(list1.listIndex)
MsgBox Primary_1
End Sub

'*Conclusion*
'*Although this isn't as convenient as setting up a bound datalist control, you will find it
'*will speed up things when using a large database file.		 Creating a simple listbox that will have
