| 项目描述: |
There are several win32 functions that require the use of a string with embedded NULLs and are terminated with an extra NULL (i will call them DZ strings for short).
An example of such a DZ string: "part1\0part2\0part3\0\0".
To name just a few of functions that work with DZ strings:
GetPrivateProfileSection
WritePrivateProfileSection
SQLConfigDataSource
As most string-functions (strcmp, strchr etc) expect a zeroterminated string, they are of little use when you have to parse a DZ string.
The CString class could be used to manipulate them, but you must be carefull not to call the non-DZ-aware CString-methods (such as Right(), Mid(), Left(), Replace() and Find()).
I decided to create a class that helps constructing and parsing those DZ strings. The class is called CDoubleZeroString and is not derived from CString.
有几个 win32 函数需要使用内部带有NULL的字符串，但仍以另一个NULL作为结束(我将其称为DZ字符串)。
这种字符串的一个例子是 "part1\0part2\0part3\0\0"。可以处理DZ字符串的函数有：
GetPrivateProfileSection
WritePrivateProfileSection
SQLConfigDataSource
大多数字符串函数都需要以NULL结尾的字符串，当你必须处理DZ字符串时，很少能找到这样的函数。
CString 类可以处理它们，但必须明白不能调用非DZ的CString-方法(如 Right(), Mid(), Left(), Replace() and Find())。我决定创建一个类，来帮助构造和分析这种DZ字符串。这个类称为CDoubleZeroString ，它不是派生于 CString。
