Mousehover

Code:

Private Sub frmGraphTT_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseHover
        sender = ChartBox
        Dim XYpoint As Point
        XYpoint.X = MousePosition.X
        XYpoint.Y = MousePosition.Y
        'ChartBox.onmousehover(e) - gives a Protected error?

        If Cregion.IsVisible(XYpoint.X, XYpoint.Y) = True Then
            Debug.Print("1209 hit")
        Else
            Debug.Print("1216 miss")

        End If
    End Sub

I have a form with a picturebox called Chartbox and I'm trying to fire a mousehover event when the mouse is over a drawn region (Cregion). My code is not working, can anyone help, please?

For starters

Code:

sender = ChartBox

The value of the sender should be assigned to an object

Secondly why are you trying to fire an onmousehover event when you haven't check to see if the box is currently under the mouse

Thirdly you should be using the picture boxes mousehover event to check whether its over a region!

And just to give you a hint look at a special property within the control which converts locations into control locations and stuff!

Goodluck
