Property Value

Type: System.Int32

Remarks

The coordinate is relative to the container of the LineShape control and is expressed in pixels.

You can also change the starting coordinates by setting the StartPoint property.

Examples

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

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

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;
    }
}
