Determine Selected Line

Hello all

I have a line drawn on picturebox.
Now i want to run some command if a mouse location is on drawn line area.
How can i do this ?

Thanks in advance.

Use the pictureboxe's _mousemove event and compare the mouse location with the x, y location of your line.
If your line is diagonal, it becomes slightly more difficult, requiring a mathematical formula

Like this ?

Code:

---

For Each Line As Line In LineS
      If e.Location.X >= Line.Start.X And e.Location.Y >= Line.Start.Y And _
                e.Location.X <= Line.End.X And e.Location.Y <= Line.End.Y Then
                'Some Command
      End If
Next

or u have other easiest way ?
a Line is saved on a List(Of Line) named Lines.

That could work. Have you tried it?

Yea its work. But i just find a easiest way.
