How to convert TCHAR to string in c++?

TCHAR t = SomeFunctionReturningTCHAR(); std::string str; #ifndef UNICODE str = t; #else std::wstring wStr = t; str = std::string(wStr. begin(), wStr. end()); #endif std::cout << str << std::endl; //<– should work!

How to convert TCHAR to string?

So depending on your compilation configuration, you can convert TCHAR* to string or wstring. To use UNICODE character set, click Project->Properties->Configuration Properties->General->Character Set, and then select “Use Unicode Character Set”.

What is TCHAR in c++?

C++ has two built in character types: char and wchar_t . TCHAR is simply a macro that expands to char in ANSI builds (i.e. _UNICODE is not defined) and wchar_t in Unicode builds ( _UNICODE is defined). There are various string types based on the TCHAR macro, such as LPCTSTR (long pointer to a constant TCHAR string).

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).

How do you define Tchar?

For Unicode platforms, TCHAR is defined as synonymous with the WCHAR type. MAPI clients can use the TCHAR data type to represent a string of either the WCHAR or char type. Be sure to define the symbolic constant UNICODE and limit the platform when it is required.

What is _bstr_t?

_bstr_t is a wrapper class that works like a smart pointer, so it will free the allocated memory when the variable is destroyed or goes out of scope.

Should I use Wstring or string?

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. The standard says nothing about the character set or encoding.

What is a Unicode string?

Unicode is a standard encoding system that is used to represent characters from almost all languages. Every Unicode character is encoded using a unique integer code point between 0 and 0x10FFFF . A Unicode string is a sequence of zero or more code points.

How do you compare Tchar strings?

A TCHAR or any string array is simply a pointer to the first character. What you’re comparing is the value of the pointer, not the string. Also, you’re assigning an array to null which is nonsensical. Use win32 variations of strcmp.

How do you assign a value to Tchar?

Use CString if you are using MFC or are comfortable tying yourself to MSFT. Use std::string or std::wstring in conjunction with the type-specific API – use CreateFileA() and CreateFileW() where appropriate.

What is wide-character string?

A wide character is a 2-byte multilingual character code. A wide-character string is represented as a wchar_t[] array. You point to the array with a wchar_t* pointer. You can represent any ASCII character as a wide character by prefixing the letter L . For example, L’\0′ is the terminating wide (16-bit) null character.

Are C++ strings Unicode?

C++ provides a wide-character type, wchar_t , which can store Unicode strings. The exact implementation of wchar_t is implementation defined, but it is often UTF-32. Now, you can write these wide-character strings to a wide-character …

Can a Tchar be converted to a string?

TCHAR is just a typedef that depending on your compilation configuration (whether you have defined UNICODE or not) defaults to char or wchar. So depending on your compilation configuration, you can convert TCHAR* to string or wstring.

How to convert Char to string in C language?

In C string is simply an array of characters but the only condition is that it must be terminated by a null character,i.e ‘\\0’. Thats it. You have now converted a character to string in C language. The string is stored in array ‘arr’. , B.Tech Bachelor of Technology in Computer Science and Engineering & Mathematics, Swami Keshvanand Institute o…

How does the char.tostring method work?

Char. To String Method Converts the value of this instance to its equivalent string representation. Converts the value of this instance to its equivalent string representation using the specified culture-specific format information. Converts the specified Unicode character to its equivalent string representation.

How to convert Char to string in C-Quora?

1.You will need to declare a new variable which can hold a string , i.e. a character array. 2. Then you need to put the your char into it as its first element 3. Finally, to convert the character array into a string, you need to put ‘\\0’ as the next element of the array. Because a string is always ‘terminated by a ‘\\0’
