问题描述
你好,
今天我有更多的写作风格"问题:
我上课时应该指定
Hello once again,
Today I have more "writing style" question:
When I have class, should I specify
<br />
<pre>#ifdef UNICODE<br />
#define CClass CClassW<br />
#else<br />
#define CClass CClassA<br />
#endif </pre><br />
并创建两个相同类的版本?
还是在类中定义数据类型?
喜欢:
and create two versions of same class?
Or rather define the data types inside the class?
Like:
#ifdef UNICODE
CMap<CString, LPCWSTR, DWORD, DWORD> m_SomeMap;
#else
CMap<CString, LPCSTR, DWORD, DWORD> m_SomeMap;
#endif
感谢所有建议,
谢谢
Appreciate all advices,
Thanks
推荐答案
为unicode和non-unicode创建不同的类名称是没有道理的.
在这里真正重要的是字符串数据类型.
因此,您的CMap
示例很有意义,因为它包含一个字符指针.
您最好使用-
CMap<CString, LPCTSTR, DWORD, DWORD> m_SomeMap;
LPCTSTR
转换为LPCSTR
或LPCWSTR
,具体取决于是否定义了UNICODE
.
我个人建议始终使用宽版本的字符串,因为Windows在内部使用这些字符串,也因为您有时会需要它们.
Creating different names of classes for unicode and non-unicode doesn''t make sense.
It''s the string data type that really matters here.
So yourCMap
example makes sense because it contains a character pointer.
You might as well use -
CMap<CString, LPCTSTR, DWORD, DWORD> m_SomeMap;
LPCTSTR
translates toLPCSTR
orLPCWSTR
depending on whetherUNICODE
is defined or not.
I would personally recommend always using the wide version of strings because Windows internally uses these and also because you''re going to need them somewhere sometime.
