VB将彩色图象黑白化典型示例代码,有需要的就下。(VB of the typical black and white color image sample code, there is a need on the next.)

字符串交叉输入，就是将一个字符串交叉的输入到了另一个字符串当中，比如： char a[4]="ABCD" char b[4]="abcd" 则char c[8]="AaBbCcDd" (Cross-string input, is to cross a string input to another string of them, such as: char a [4] = "ABCD" char b [4] = "abcd" While char c [8] = "AaBbCcDd" )

一个简单的计算器程序，实现了加、减、乘、除计算(A simple calculator program to achieve the add, subtract, multiply, divide computing)

USACO第10题，Marry乳业从一些奶农手中采购牛奶，并且每一位奶农为乳制品加工企业提供的价格是不同的。此外，就像每头奶牛每天只能挤出固定数量的奶，每位奶农每天能提供的牛奶数量是一定的。每天Marry乳业可以从奶农手中采购到小于或者等于奶农最大产量的整数数量的牛奶。 给出Marry乳业每天对牛奶的需求量，还有每位奶农提供的牛奶单价和产量。计算采购足够数量的牛奶所需的最小花费。 (Give the requirement of milk and the amount that they offer.)

说明：  一个复杂的工程通常可以分解成一组小任务的集合,不错(A complex project can usually be broken down into a collection of small tasks.)

这是用VB写的PCB钻孔机的钻孔数据处理程序，可以对钻孔精度进行分析。(It is written in VB PCB drilling machine drilling data processing program, you can drill precision analysis.)

这是C++Primer的书籍的源代码，包括课后习题的答案，是份很不错的代码，尤其针对初学者(This is the source code of C++Primer books, including after-school exercises, answers, were very good code, especially for beginners)

Factory 模式的两个最重要的功能： 1）定义创建对象的接口，封装了对象的建； 2）使得具体化类的工作延迟到了子类中。 (Factory mode two most important functions: 1) the definition of an object to create an interface that encapsulates the construction objects 2) makes specific class work delayed to subclasses.)
