[RESOLVED] "Variable 'cnn' hides a variable in an enclosing block

Hi!

I have the following code but I get blue squiggly line in cnn and when i point my mouse pointer on it i see this message "Variable 'cnn' hides a variable in an enclosing block"

Code:

---

  Private Sub BtnLockUnlock_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnLockUnlock.Click
        Dim IsLocked As Boolean = FpSpread1.ActiveSheet.DefaultStyle.Locked
        ''Dim imageIcon As String = IIf(IsLocked, "lock_icon.gif", "lock_icon_open.gif")

        If IsLocked = True Then

            FpSpread1.ActiveSheet.DefaultStyle.Locked = False

            Using cnn As New SqlConnection("My.Settings.ConnectionString")
                Using cnn As New SqlCommand("UPDATE tblLockUnlock SET Locked=@Bol WHERE Period=@Per", cnn)
                    cnn.Parameters.AddWithValue("@Bol", "False")
                    cnn.Parameters.AddWithValue("@Per", "1G_HS")
                    cnn.ExecuteNonQuery()
                End Using
            End Using

        Else

            FpSpread1.ActiveSheet.DefaultStyle.Locked = True
       
        End If
        Call LockUnlockImage()
    End Sub

i have this on form load

Code:

---

cnn = New SqlConnection(My.Settings.ConnectionString)

---

what's wrong with my code?

You have two nested Using blocks and they both declare a variable named 'cnn'. How can 'cnn' refer to a SqlConnection and a SqlCommand?

thanks jm!
