Examples

The following example demonstrates how to change the direction of a diagonal line by changing the X1, Y1, X2, and Y2 properties.

Microsoft.VisualBasic.PowerPacks.ShapeContainer canvas = 
    new Microsoft.VisualBasic.PowerPacks.ShapeContainer();
Microsoft.VisualBasic.PowerPacks.LineShape line1 = 
    new Microsoft.VisualBasic.PowerPacks.LineShape(10, 10, 200, 10);
private void LineDirection_Load(System.Object sender, System.EventArgs e)
{
    // Set the form as the parent of the ShapeContainer.
    canvas.Parent = this;
    // Set the ShapeContainer as the parent of the LineShape.
    line1.Parent = canvas;
}
private void LineDirection_Click(object sender, System.EventArgs e)
{
    ChangeDirection();
}
private void ChangeDirection()
{
    if (line1.X1 == line1.Y2)
    {
        line1.X2 = 10;
        line1.Y2 = 200;
    }
    else
    {
        line1.X2 = 200;
        line1.Y2 = 10;
    }
}

Dim canvas As New Microsoft.VisualBasic.PowerPacks.ShapeContainer
Dim line1 As New Microsoft.VisualBasic.PowerPacks.LineShape(10, 10,
    200, 10)
Private Sub LineDirection_Load(ByVal sender As System.Object,
    ByVal e As System.EventArgs) Handles MyBase.Load
    ' Set the form as the parent of the ShapeContainer.
    canvas.Parent = Me
    ' Set the ShapeContainer as the parent of the LineShape.
    line1.Parent = canvas
End Sub
Private Sub LineDirection_Click(ByVal sender As Object,
    ByVal e As System.EventArgs) Handles Me.Click
    ChangeDirection()
End Sub
Private Sub ChangeDirection()
    If line1.X1 = line1.Y2 Then
        line1.X2 = 10
        line1.Y2 = 200
    Else
        line1.X2 = 200
        line1.Y2 = 10
    End If
End Sub
