Property Value

Type: System.Drawing.Point
A Point structure that represents the ending coordinates of the line.

Remarks

The coordinates are relative to the container of the LineShape control and are expressed in pixels.

You can also change the ending coordinates by setting the X2 and Y2 properties.

Examples

The following example switches a LineShape from a horizontal orientation to a diagonal orientation, and then to a vertical orientation, using the StartPoint as an axis.

Dim canvas As New Microsoft.VisualBasic.PowerPacks.ShapeContainer
Dim line1 As New Microsoft.VisualBasic.PowerPacks.LineShape(10, 10, 200, 10)
Private Sub Form1_Load() 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 Form1_Click() Handles Me.Click
    ChangeOrientation()
End Sub
Private Sub ChangeOrientation()
    Static direction As String = "horizontal"
    If direction = "horizontal" Then
        ' Change the orientation to diagonal.
        line1.EndPoint = New System.Drawing.Point(200, 200)
        direction = "diagonal"
    ElseIf direction = "diagonal" Then
        ' Change the orientation to vertical.
        line1.EndPoint = New System.Drawing.Point(line1.X1, 200)
        direction = "vertical"
    Else
        ' Change the orientation to horizontal.
        line1.EndPoint = New System.Drawing.Point(200, line1.Y1)
        direction = "horizontal"
    End If
End Sub

        Microsoft.VisualBasic.PowerPacks.ShapeContainer canvas = 
            new Microsoft.VisualBasic.PowerPacks.ShapeContainer();
        Microsoft.VisualBasic.PowerPacks.LineShape line1 = 
            new Microsoft.VisualBasic.PowerPacks.LineShape(10, 10, 200, 10);
        string direction;
        private void Form1_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;
            direction = "horizontal";
        }
        private void Form1_Click(object sender, System.EventArgs e)

                line1.EndPoint = new System.Drawing.Point(200, 200);
                direction = "diagonal";
            }
            else if (direction == "diagonal")
            {
                line1.EndPoint = new System.Drawing.Point(line1.X1, 200);
                direction = "vertical";
            }
            else
            {
                // Change the orientation to horizontal.
                line1.EndPoint = new System.Drawing.Point(200, line1.Y1);
