LPCSTR，LPCTSTR和LPTSTR [英] LPCSTR, LPCTSTR and LPTSTR

问题描述

LPCSTR，LPCTSTR和LPTSTR有什么区别?

为什么需要执行此操作以将字符串转换为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);

推荐答案

回答问题的第一部分:

LPCSTR是指向const字符串的指针(LP表示长指针 )

LPCSTR is a pointer to a const string (LP means Long Pointer)

LPCTSTR是指向const TCHAR字符串的指针(TCHAR是宽字符还是char，具体取决于您的项目中是否定义了UNICODE)

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是指向(非常量)TCHAR字符串的指针

LPTSTR is a pointer to a (non-const) TCHAR string

在过去的实践中，为简单起见，我们省略了指向"的指针，但正如lightness-races-or-bit所提到的，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.

这是很棒的 codeproject文章描述了C ++字符串(请参阅2/3比较不同类型的图表的方式

This is a great codeproject article describing C++ strings (see 2/3 the way down for a chart comparing the different types)
