CString 操作详解[外文翻译]

CStrings are a useful data type. They greatly simplify a lot of operations in MFC, making it much more convenient to do string manipulation. However, there are some special techniques to using CStrings, particularly hard for people coming from a pure-C background to learn. This essay discusses some of these techniques.
Much of what you need to do is pretty straightforward. This is not a complete tutorial on CStrings, but captures the most common basic questions.
CString concatenation
Formatting (including integer-to-CString)
Converting CStrings to integers
Converting between char * to a CString
char * to CString
CString to char * I: Casting to LPCTSTR
CString to char * II: Using GetBuffer
CString to char * III: Interfacing to a control
CString to BSTR
BSTR to CString (New 30-Jan-01)
VARIANT to CString (New 24-Feb-01)
Loading STRINGTABLE resources (New 22-Feb-01)
CStrings and temporary objects
CString efficiency
String Concatenation
One of the very convenient features of CString is the ability to concatenate two strings. For example if we have
CString gray("Gray");
CString cat("Cat");
CString graycat = gray + cat;
is a lot nicer than having to do something like ......
CString 操作详解
原著：Joseph M. Newcomer
CString 是一种很有用的数据类型。它们很大程度上简化了MFC中的许多操作，使得MFC在做字符串操作的时候方便了很多。不管怎样，使用CString有很多特殊的技巧，特别是对于纯C背景下走出来的程序员来说有点难以学习。这篇文章就来讨论这些技巧。
使用CString可以让你对字符串的操作更加直截了当。这篇文章不是CString的完全手册，但囊括了大部分常见基本问题。
这篇文章包括以下内容：
CString 对象的连接
格式化字符串（包括 int 型转化为 CString ）
CString 型转化成 int 型
CString 型和 char* 类型的相互转化
char* 转化成 CString
CString 转化成 char* 之一：使用LPCTSTR强制转化
CString 转化成 char* 之二：使用CString对象的GetBuffer方法
CString 转化成 char* 之三: 和控件的接口
载入字符串表资源；
CString 和临时对象；
CString 的效率；
总结
下面我分别讨论。
1、CString 对象的连接
能体现出 CString 类型方便性特点的一个方面就字符串的连接，使用 CString 类型，你能很方便地连接两个字符串，正如下面的例子：
CString gray("Gray");
CString cat("Cat");
CString graycat = gray + cat;
要比用下面的方法好得多：
char gray[] = "Gray";
char cat[] = "Cat";
char * graycat = malloc(strlen(gray) + strlen(cat) + 1);
strcpy(graycat, gray);
strcat(graycat, cat) ......
