(CString 是typedef,可使 CStringT 专用于处理 CString 支持的字符数据类型。) CString 不会将字符数据内部存储为 C 样式 null 结尾的字符串。 相反,CString 会跟踪字符数据的长度,以便可以更安全地观察其所需的数据和空间。 CString 接受C 样式字符串,并且提供作为 C 样式字符串访问字符数据的方式。 本主题包含...

If you must use the C run-time string functions, you can use the techniques described in Converting to C-Style Null-Terminated Strings_core_using_cstring_as_a_c.2d.style_null.2d.terminated_string. You can copy theCStringobject to an equivalent C-style string buffer, perform your operations...

Using CString objects with variable argument functions Specifying CString formal parameters Converting to C-Style Null-Terminated Strings Consider the following two cases: In the simplest case, you can cast aCStringobject to be anLPCTSTR. The LPCTSTR type conversion operator returns a pointer to a re...
当需要CString , 而传入了 const char* 时(其实 char* 也可以),C++编译器则自动调用CString的构造函数来构造临时的 CString对象。 因此CString 和 LPCTSTR 基本可以通用。 但是LPTSTR又不同了,他是 char*, 意味着你随时可能修改里面的数据,这就需要内存管理了(如字符串变长,原来的存贮空间就不够了,则需要重新...
Using CString objects by variable argument functions Specifying CString formal parameters Using CString as a C-Style Null-Terminated String To use a CString object as a C-style string, cast the object to LPCTSTR. In the following example, the CString returns a pointer to a read-only C-styl...
