and you have tried....?

8 fixed lables? are you putting them in Panel or gropu box?
And what are the names you have given them to identify the sequence?

yes 8 fixed labels..
i am putting them in a form.

What is the name u gave to the label to identify?

See if this helps you... you need to give the propernames what you gave in design.

Private Sub Label3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label3.Click, Label4.Click, Label5.Click, Label6.Click
        Dim blblclick1 As Boolean
        Dim blblclick2 As Boolean
        Dim blblclick3 As Boolean
        Dim blblclick4 As Boolean

        Select Case sender.name.ToString
            Case "Label1"
                blblclick1 = True
            Case "Label2"
                If blblclick1 = False Then
                    MessageBox.Show("Please click label 1 first")
                End If
            Case "Label3"
                If blblclick2 = False Then
                    MessageBox.Show("Please click label 2 first")
                End If
            Case "Label4"
                If blblclick3 = False Then
                    MessageBox.Show("Please click label 3 first")
                End If
            Case "Label5"
                If blblclick4 = False Then
                    MessageBox.Show("Please click label 4 first")
                End If

        End Select

    End Sub

Here is the code you want. It check all the possibilities.
Let me know what you think:

Private labelClicked As Integer
Public Sub New()
	Dim labels As Label() = {label1, label2, label3, label4, label5, label6, _
		label7, label8}
	For i As Integer = 0 To labels.Length - 1
		labels(i).Tag = i
		labels(i).Click += New EventHandler(AddressOf Labels_Click)
End Sub

Private Sub Labels_Click(sender As Object, e As EventArgs)
	Dim l As Label = TryCast(sender, Label)
	Dim currentTag As Integer = CInt(l.Tag)
	If labelClicked < 8 Then
		If labelClicked <> currentTag Then
			If labelClicked < currentTag Then
				MessageBox.Show([String].Format("Please select label{0} before label{1}.", (labelClicked + 1), (currentTag + 1)))
				MessageBox.Show([String].Format("Label{0} has already been selected.", (currentTag + 1)))
			End If
			labelClicked += 1
			'color selected label for example:
			l.ForeColor = Color.Red
			If labelClicked.Equals(8) Then
				MessageBox.Show("All labels are selected now.")
			End If
		End If
		MessageBox.Show("You have already selected all the labels.")
	End If
End Sub
