NumericUpDown - up or down???

Is there any way I can recognize whether I`ve clicked the upButton or the DownButton in NumericUpDown-box??

one way i can think of is defining a static value in value_changed event and compare it with current value.

I`m afraid I need a dynamic value to compare the value with :(
I got 4 different operations to choose between and I need spesificly to know whether the value changed up or down.

But I`m working on a way to locate the boxes in the form, which seems to work okay. But I also need to know where the form is on the screen. Got any tips, how to find out the forms top-position on the screen??

I solved my problem like this:

1)Add eventhandler to NumericUpDown
AddHandler numBox.ValueChanged, AddressOf NumericUpDown_ValueChanged

2)Find the exact position to the NumericUpDown-box

If ((Cursor.Position.Y - 30) < ((sender.top + Form.ActiveForm.DesktopLocation.Y) + (sender.height / 2))) Then
counter -= 1
ElseIf ((Cursor.Position.Y - 30) > ((sender.top + Form.ActiveForm.DesktopLocation.Y) + (sender.height / 2))) Then
counter += 1
End If

I am sorry about static value. I meant an Static Variable. That is a variable tat its value does not reset each time the event is fired.

put this code in change event of your numeric updown

VB Code:

Static Dim original_Value as Single=0 'This is the original value you give to your numericupdown
 
If myNumUpDwn.Value > original_value Then
Messagebox.Show("Going UP") ' or any toher code
Elseif myNumUpDwn.Value< original_value Then
Messagebox.Show("Going Down") 'or any other code
Else
Messagebox.Show("No Change") ' Any code here
End if

What about something like this:

VB Code:

Dim fPreviousValue As Single = 0
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        With NumericUpDown1
            .DecimalPlaces = 1
            .Increment = 0.5
            .Maximum = 3
            .Minimum = -1
            fPreviousValue = .Value
        End With
    End Sub
 
    Private Sub NumericUpDown1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NumericUpDown1.ValueChanged
        'Determine which way the value of the control has changed
        If NumericUpDown1.Value > fPreviousValue Then
            lblStatus.Text = "UP"
        ElseIf NumericUpDown1.Value < fPreviousValue Then
            lblStatus.Text = "down"
        Else
            lblStatus.Text = ""
        End If
        fPreviousValue = NumericUpDown1.Value
    End Sub

Hey, tanks MrGTI! That was exactly what I awas looking for. :D
