CString函数 [英] CString functions
问题描述
我想对字符串执行以下操作：
1）检查前四个字符是否为DATA
2）从以下字符串DATA 123 xyz中获取中间的单词。 （
中间词是可变长度） - 提取123。
3）从以下字符串中获取最后一个单词/数字数据发送1467436267
我应该使用哪些功能来实现这一目标？我是C ++的新手，并且发现
字符串操作很棘手。
I want to do the following to strings:
1) Check if first four characters are "DATA"
2) Get the middle ''word'' from the following string "DATA 123 xyz" (the
middle word is variable length) - extract the "123".
3) Get the last word/number from the following string "DATA SEND 1467436267"
What functions should I use to achieve this? I''m new to C++ and finding
string manipulation tricky.

如果你使用CString，它为此提供了很多设施。看看
at -
CString :: Left
CString :: Mid
CString ::正确
CString ::查找
CString :: Tokenize
问候，
Hugh
If you use CString it provides lots of facilities for this. Have a look
at -
CString::Left
CString::Mid
CString::Right
CString::Find
CString::Tokenize
Regards,
Hugh

CString不是标准的C ++类。查看microsoft.public。*
newsgrouop for CString。
对于std :: string，请使用：
std :: string :: substr（），
std :: string :: find_first_of（）
std :: string :: find_last_of（）
CString is not a standard C++ class. Look in a microsoft.public.*
newsgrouop for CString.
For std::string, use :
std::string::substr(),
std::string::find_first_of()
std::string::find_last_of()

....这是发布到microsoft.public.vc.language和
microsoft.public.vc.mfc我可能会补充说，我们最近想出了CString规则的
结论！ :)

.... This is posted to microsoft.public.vc.language and
microsoft.public.vc.mfc where, I might add, we recently came up with the
conclusion that CString rules! :)
