Examples

The following code example shows how to use the FromPoint method. This example creates a Point referencing the X and Y coordinates passed by a MouseEventArgs, and then uses the FromPoint method to determine if the point clicked is on the primary screen.

private:
   void Form1_MouseDown( Object^ /*sender*/, System::Windows::Forms::MouseEventArgs^ e )
   {
      Point p = Point(e->X,e->Y);
      Screen^ s = Screen::FromPoint( p );
      if ( s->Primary )
      {
         MessageBox::Show( "You clicked the primary screen" );
      }
      else
      {
         MessageBox::Show( "This isn't the primary screen" );
      }

private void Form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
    Point p = new Point(e.X, e.Y);
    Screen s = Screen.FromPoint(p);
    
if (s.Primary)
{
    MessageBox.Show("You clicked the primary screen");
}
else
{
    MessageBox.Show("This isn't the primary screen");
}

Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown
    Dim p As New System.Drawing.Point(e.X, e.Y)
    Dim s As System.Windows.Forms.Screen = Screen.FromPoint(p)

    If s.Primary = True Then
        MessageBox.Show("You clicked the primary screen")
    Else
        MessageBox.Show("This isn't the primary screen")
    End If
End Sub
