The and coordinates of the point of intersection of two non-vertical lines can easily be found using the following substitutions and rearrangements. Suppose that two lines have the equations and where and are the slopes (gradients) of the lines and

You must add a timer and a button to the form in advance.   Private void button#click (Object sender, eventargs e) { timer1.enabled = true; } private point pt1 = new point (10, 10 ); // start coordinate private point pt2 = new point (300,3

  Using System; Using System. Collections. Generic; Using System. Text; Using System. Drawing; Using System. ComponentModel; Using System. Windows. Forms;   Namespace Line { Public class LineControl: Control { Private LineType m_lineType = LineType.

The source code from other places is problematic. /// /// calculate the intersection of two straight lines /// /// coordinate 1 of L1 Points /// L1 coordinate 2 /// L2 coordinate 1 /// L2 coordinate 2 /// public static PointF

We usually think that the buttons provided by the system are not beautiful enough. At this time, we can define a button by ourselves to meet our own needs. Here we can implement a rounded button. You need to create an xml file in the drawable folder
