no duplicate value in the comboBox(Resolved)

hi,

I want to avoid the duplicate course tittle in the comboBox when I load the form. It is allow to add new course tittle if there is not in the combobox. I have try to search from the examples but none of them are relevant. Please help.

Private Sub Form_Load()
rs.Open "select * from Course ", con, adOpenDynamic, adLockPessimistic

while Not rs.EOF
cbProg.AddItem (rs("CourseTittle"))
rs.MoveNext
Wend

end sub

I don't think its possible through SQL, so you might have to do something like this:

VB Code:

Private Sub Form_Load()
rs.Open "select * from Course ", con, adOpenDynamic, adLockPessimistic
 
While Not rs.EOF
    [b]For i = 0 To cbProg.ListCount - 1
        If Not (rs("CourseTitle") = cbProg.List(i)) Then[/b]
            cbProg.AddItem (rs("CourseTittle"))
            rs.MoveNext
        [b]End If
    Next i[/b]
Wend
 
End Sub

Hope that helps,
