Creates a black pen.
Creates an array of seven points for the vertices of the polygon.
Draws the polygon to the screen.
public: void DrawPolygonPoint( PaintEventArgs^ e ) { // Create pen. Pen^ blackPen = gcnew Pen( Color::Black,3.0f ); // Create points that define polygon. Point point1 = Point(50,50); Point point2 = Point(100,25); Point point3 = Point(200,5); Point point4 = Point(250,50); Point point5 = Point(300,100); Point point6 = Point(350,200); Point point7 = Point(250,250); array<Point>^ curvePoints = {point1,point2,point3,point4,point5,point6,point7}; // Draw polygon to screen. e->Graphics->DrawPolygon( blackPen, curvePoints ); }
