TreeView控件用来显示信息的分级视图，如同Windows里的资源管理器的目录，动态添加内容到树形结构(content of the treeView)

说明：  TCP/ip通讯客户端的程序。VB程序编写WINSOCK控件应用(TCP/ip messaging client program. VB programming WINSOCK Control Applications)

渐变背景,在窗体中从上至下依次绘制多个矩形，使它们的填充色从蓝变化到黑，就能很好地模拟出渐变效果(graded background, in which top-down windows were drawing more than rectangular, filling their color changes from blue to black. it will be able to simulate effects of graded)

可以动态显示Gif的vb2008的RichTextBox，不带第三方控件的自定义控件 ，可以自由扩充 完全类似于ＱＱ的动态表情显示哦 (Can dynamically display the Gif vb2008 RichTextBox, a custom control without third party control ，可以自由扩充 , free to expand 完全类似于ＱＱ的动态表情显示哦 Dynamic expression is completely similar to the QQ display. )

固高8轴运动卡，vb例程，有激光4轴运行G代码的源程序(8 axis motion card, VB routine, there are 4 axes of laser running G source code)

得到所有运行的com组件，ROT,RunningObjectTable(By all run com components, ROT, IRunningObjectTable)

基于DSP5509的SDRAM应用实例，含有CCS4环境下的编程源代码(DSP5509 SDRAM example based on the CCS4 environment)

TMS320C6678 GPIO源代码，TMS320C6678是TI公司推出的一款8核DSP，具有强大的并行处理能力，GPIO主要用于通用管脚的输入输出，可以响应中断，代码书写简单，可以用于简单的命令控制(TMS320C6678 GPIO source code, TMS320C6678 is TI has introduced an 8-core DSP, a powerful parallel processing capability, GPIO mainly used for general purpose input and output pins that can respond to the interrupt, write simple code, can be used for simple command control)

BF609 DSP定时器程序例程，初学者通过这个例程可以学会定时器的编程方法(BF609 DSP timer routine, beginners can learn through this routine Timer programming)

一般地，把三角形的三个角A，B，C和它们的对边a，b，c叫做三角形的元素。已知三角形的几个元素求其他元素的过程叫做解三角形。解三角形，常用到正弦定理和余弦定理和面积公式等。正弦定理a/sinA=b/sinB=c/sinC=2R（2R在同一个三角形中是恒(The Triangle software, wrote)
