Unicode和ASCII支持 [英] Unicode and ASCII support

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 your CMap example makes sense because it contains a character pointer.
You might as well use -
CMap<CString, LPCTSTR, DWORD, DWORD> m_SomeMap;


LPCTSTR translates to LPCSTR or LPCWSTR depending on whether UNICODE 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.
