LPCSTR
、LPCTSTR
和 LPTSTR
有什么区别?
What the difference between LPCSTR
, LPCTSTR
and LPTSTR
?
为什么我们需要这样做将字符串转换为LV
/_ITEM
结构变量pszText
:
Why do we need to do this to convert a string into a LV
/ _ITEM
structure variable pszText
:
LV_DISPINFO dispinfo;
dispinfo.item.pszText = LPTSTR((LPCTSTR)string);
回答您问题的第一部分:
To answer the first part of your question:
LPCSTR
是一个指向 const 字符串的指针(LP 表示 Long指针)
LPCSTR
is a pointer to a const string (LP means Long Pointer)
LPCTSTR
是一个指向 const TCHAR
字符串的指针,(TCHAR
是宽字符还是字符取决于 UNICODE 是否在你的项目)
LPCTSTR
is a pointer to a const TCHAR
string, (TCHAR
being either a wide char or char depending on whether UNICODE is defined in your project)
LPTSTR
是一个指向(非常量)TCHAR
字符串
LPTSTR
is a pointer to a (non-const) TCHAR
string
在实践中,过去在讨论这些时,为了简单起见,我们省略了指向 a 的指针"短语,但正如 lightness-races-in-orbit 所述,它们都是指针.
In practice when talking about these in the past, we've left out the "pointer to a" phrase for simplicity, but as mentioned by lightness-races-in-orbit they are all pointers.
这是一篇很棒的 codeproject 文章,描述了 C++ 字符串(参见 2/3比较不同类型的图表的下降方式)
This is a great codeproject article describing C++ strings (see 2/3 the way down for a chart comparing the different types)
