'Declaration
Public Overrides Function HitTest ( _
x As Integer, _
y As Integer _
) As Boolean
public override bool HitTest(
int x,
int y
)
public:
virtual bool HitTest(
int x,
int y
) override
abstract HitTest :
x:int *
y:int -> bool
override HitTest :
x:int *
y:int -> bool
public override function HitTest(
x : int,
y : int
) : boolean
Parameters
x
Type: System.Int32The horizontal screen coordinate.
y
Type: System.Int32The vertical screen coordinate.
Return Value
Type: System.Boolean
true if the shape control is located at the specified coordinates; otherwise, false.

Examples
The following example demonstrates how to use the HitTest method of the OvalShape control to determine whether the pointer is positioned over the control when the SPACEBAR is pressed.
Private Sub Form1_PreviewKeyDown(
ByVal sender As Object,
ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs
) Handles Me.PreviewKeyDown
If e.KeyCode = Keys.Space Then
Dim px As Integer
Dim py As Integer
Dim hit As Boolean
px = MousePosition.X
py = MousePosition.Y
hit = OvalShape1.HitTest(px, py)
MsgBox(CStr(hit))
End If
End Sub
private void form1_PreviewKeyDown(object sender,
System.Windows.Forms.PreviewKeyDownEventArgs e)
{
if (e.KeyCode == Keys.Space)
{
int px;
int py;
bool hit;
string result;
px = MousePosition.X;
py = MousePosition.Y;
hit = ovalShape1.HitTest(px, py);
result = hit.ToString();
MessageBox.Show(result);
}
}
