Examples
The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:
Creates a black pen.
Creates a rectangle to bound an ellipse.
Draws the ellipse to the screen.
private:
void DrawEllipseRectangle( PaintEventArgs^ e )
{
// Create pen.
Pen^ blackPen = gcnew Pen( Color::Black,3.0f );
// Create rectangle for ellipse.
Rectangle rect = Rectangle(0,0,200,100);
// Draw ellipse to screen.
e->Graphics->DrawEllipse( blackPen, rect );
}
private void DrawEllipseRectangle(PaintEventArgs e)
{
// Create pen.
Pen blackPen = new Pen(Color.Black, 3);
// Create rectangle for ellipse.
Rectangle rect = new Rectangle(0, 0, 200, 100);
// Draw ellipse to screen.
e.Graphics.DrawEllipse(blackPen, rect);
}
Private Sub DrawEllipseRectangle(ByVal e As PaintEventArgs)
' Create pen.
Dim blackPen As New Pen(Color.Black, 3)
' Create rectangle for ellipse.
Dim rect As New Rectangle(0, 0, 200, 100)
' Draw ellipse to screen.
e.Graphics.DrawEllipse(blackPen, rect)
