How do I convert a "pointer to const TCHAR" to a "std::string"?

Question

I have a class which returns a typed pointer to a "const TCHAR". I need to convert it to a std::string but I have not found a way to make this happen.

Can anyone provide some insight on how to convert it?

Answer 1

Depending on your compiling settings, TCHAR is either a char or a WCHAR (or wchar_t).

If you are using the multi byte character string setting, then your TCHAR is the same as a char. So you can just set your string to the TCHAR* returned.

If you are using the unicode character string setting, then your TCHAR is a wide char and needs to be converted using WideCharToMultiByte.

If you are using Visual Studio, which I assume you are, you can change this setting in the project properties under Character Set.

Do everything Brian says. Once you get it in the codepage you need, then you can do:

std::string s(myTchar, myTchar+length);

or

std::wstring s(myTchar, myTchar+length);

to get it into a string.
