) As Shape
public Shape GetChildAtPoint(

Parameters
- point
Type: System.Drawing.Point
Return Value
Type: Microsoft.VisualBasic.PowerPacks.Shape
A Shape that represents the shape that is located at the specified point.
Remarks
If there is no shape at the specified point, the GetChildAtPoint method does nothing.
Observação
The pt parameter returns a Point expressed in screen coordinates. This must be converted to client coordinates by using the PointToScreen method.
Examples
The following example demonstrates how to use the GetChildAtPoint method to return the shape located where the user clicks. This example requires that you have at least one RectangleShape control on a form.
Private Sub ShapeContainer1_MouseDown(
ByVal sender As Object,
ByVal e As System.Windows.Forms.MouseEventArgs
) Handles ShapeContainer1.MouseDown
Dim sh As Shape
' Find the shape at the point where the mouse was clicked.
sh = ShapeContainer1.GetChildAtPoint(New Point(e.X, e.Y))
MsgBox(sh.Name)
End Sub
private void shapeContainer1_MouseDown(object sender,
System.Windows.Forms.MouseEventArgs e)
{
Shape sh;
// Find the shape at the point where the mouse was clicked.
sh = shapeContainer1.GetChildAtPoint(new Point(e.X, e.Y));
MessageBox.Show(sh.Name);
}
