Draws one or more straight lines.
Points to an array of POINT data structures that contains the vertices of the line.
Specifies the number of points in the array.
Nonzero if the function is successful; otherwise 0.
A line is drawn from the current position to the first point specified by the lpPoints parameter by using the current pen. For each additional line, the function draws from the ending point of the previous line to the next point specified by lpPoints. PolylineTo moves the current position to the ending point of the last line. If the line segments drawn by this function form a closed figure, the figure is not filled.
