How do you convert Wstring to Lpcwstr?

4 Answers. Simply use the c_str function of std::w/string . If LPCTSTR is const char* then there’s no reason you should be using std::wstring . Conversely, if you think you should be using std::wstring , set the UNICODE flag in your project options.

What is the difference between Wstring and string in C++?

The only difference between a string and a wstring is the data type of the characters they store. A string stores char s whose size is guaranteed to be at least 8 bits, so you can use strings for processing e.g. ASCII, ISO-8859-15, or UTF-8 text.

Why is Codecvt deprecated?

Here is some additional rationale of deprecation.” As the Unicode standard and security experts point out, ill-formed UTF can be and has been used as an attack vector. Yet the facets don’t provide the safe forms of error handling as their defaults, and it is far to hard to use them in a safe way.

What is Wstring C++?

std::wstring. typedef basic_string wstring; Wide string. String class for wide characters. This is an instantiation of the basic_string class template that uses wchar_t as the character type, with its default char_traits and allocator types (see basic_string for more info on the template).

What is Wchar_t C++?

The wchar_t type is an implementation-defined wide character type. In the Microsoft compiler, it represents a 16-bit wide character used to store Unicode encoded as UTF-16LE, the native character type on Windows operating systems. ( char8_t is new in C++20 and requires the /std:c++20 or /std:c++latest compiler option.)

What is Lpwstr C++?

The LPWSTR type is a 32-bit pointer to a string of 16-bit Unicode characters, which MAY be null-terminated. The LPWSTR type specifies a pointer to a sequence of Unicode characters, which MAY be terminated by a null character (usually referred to as “null-terminated Unicode”).

What is Wstring data type?

The data type WSTRING is interpreted in Unicode format as opposed to the data type STRING (ASCII). As a result of this coding, the number of displayed characters for WSTRING depends on the characters. The data type requires 1 WORD of memory per character plus 1 WORD of extra memory. Each STRING requires only 1 byte.

What is the difference between char and wchar_t?

char is used for so called ANSI family of functions (typically function name ends with A ), or more commonly known as using ASCII character set. wchar_t is used for new so called Unicode (or Wide) family of functions (typically function name ends with W ), which use UTF-16 character set.

What is Lpstr C++?

An LPSTR is a Long Pointer to a STRing, it’s basically a char*, a C string. The 16 bit x86 architecture has a notion of a near and far pointer which you can ignore these days. So a string is an array of chars and the char* starts to the beginning of the range.
