Hi,
Help me to get the following program working..It is a simple example of a database
but I get a"Compile error" saying "User-defined type not defined" for the underlined lines below...
Could you please correct my code?
thanks...

VB Code:

Dim [U]rsMyRS As Recordset[/U]
Dim dbMyDB As Database
Private Sub cmdUpdate_Click()
rsMyRS.Edit
rsMyRS!Phone = txtPhone.Text
rsMyRS.Update
End Sub
Private Sub cmdDelete_Click()
rsMyRS.Delete
lstRecords.RemoveItem lstRecords.ListIndex
End Sub
Private Sub cmdNew_Click()
rsMyRS.AddNew
rsMyRS!Name = "A New Person"
lstRecords.AddItem rsMyRS!Name
lstRecords.ItemData(lstRecords.NewIndex) = rsMyRS!ID
rsMyRS!Phone = "Person's Phone Number"
rsMyRS.Update
End Sub
Private Sub Form_Load()
Set dbMyDB = OpenDatabase("C:\MyDatabase.mdb")
Set rsMyRS = dbMyDB.OpenRecordSet("MyTable", dbOpenDynaset)
If Not rsMyRS.EOF Then rsMyRS.MoveFirst
Do While Not rsMyRS.EOF
    lstRecords.AddItem rsMyRS!Name
    lstRecords.ItemData(lstRecords.NewIndex) = rsMyRS!ID
    rsMyRS.MoveNext
Loop
End Sub
Private Sub lstRecords_Click()
rsMyRS.FindFirst "ID=" & Str(lstRecords.ItemData(lstRecords.ListIndex))
txtPhone.Text = rsMyRS!Phone
End Sub

Include the DAO reference in your program and if it is already included prefix your definitions with the appropiate reference.

Dim rsMyRS As DAO.Recordset

You should always do this for there are different ypes of recordsets (as well as other definitions).
