Description: While studying electronic engineering and computer science, I participated in a compiler workshop where we had to write our own programming language. To view and analyse the syntax tree for a given program, I wrote a custom drawn tree component those days. The original component was written in Java and I thought it might be useful to have it as a CTreeCtrl derivate. In contrast to some other custom drawn tree controls at CodeProject, this one does not has its own data structure for representing the tree. This means that you do not have to write different code for inserting the tree items when you want to switch from CTreeCtrl. Because this control inherits from CTreeCtrl, it is very easy to activate the stock-functionality which draws the tree in the traditional way.-While studying an electronic engineering d computer science.

Description: 两路单极性HDB3+和HDB3-信号，经映射模块后完成单极性到双极性信号的数字转化，该模块由设计文件ys.v完成。由于映射后得到的是双极性归零码，通过该模块得到双极性非归零码。该模块由设计文件delay.v完成-Two unipolar HDB3-signals HDB3+, and by the mapping module to complete unipolar to bipolar signal digital conversion, the module completed by the design documents ys.v. As the map is obtained by bipolar zero code, through the module are bipolar NRZ. The module is completed by the design documents delay.v

HSV颜色空间
HSV(hue,saturation,value)颜色空间的模型对应于圆柱坐标系中的一个圆锥形子集，圆锥的顶面对应于V=1. 它包含RGB模型中的R=1，G=1，B=1 三个面，所代表的颜色较亮。色彩H由绕V轴的旋转角给定。红色对应于 角度0° ，绿色对应于角度120°，蓝色对应于角度240°。在HSV颜色模型中，每一种颜色和它的补色相差180° 。 饱和度S取值从0到1，所以圆锥顶面的半径为１。HSV颜色模型所代表的颜色域是CIE色度图的一个子集，这个 模型中饱和度为百分之百的颜色，其纯度一般小于百分之百。在圆锥的顶点(即原点)处，V=0,H和S无定义， 代表黑色。圆锥的顶面中心处S=0，V=1,H无定义，代表白色。从该点到原点代表亮度渐暗的灰色，即具有不同 灰度的灰色。对于这些点，S=0,H的值无定义。可以说，HSV模型中的V轴对应于RGB颜色空间中的主对角线。 在圆锥顶面的圆周上的颜色，V=1，S=1,这种颜色是纯色。HSV模型对应于画家(Knowledge of color patterns:
HSV color space
HSV (hue, saturation, value) color space model corresponds to a conical subset in cylindrical coordinate system, the corresponding top cone in V=1. which contains the RGB model of R=1, G=1, B=1 three, the color is bright. The color H is given by the rotation angle around the V axis. The red corresponds to the angle 0 degrees, the green corresponds to the angle 120 degrees, the blue corresponds to t)
