I just change General -> Character Set := "Use Unioncode Character set" and its now working (char *) tcharr ; – Orcein

Answer 1

Honestly, I don't know how to do it with arrays but with pointers, Microsoft provides us with some APIs, such as wctomb and wcstombs. First one is less secure than the second one. So I think you can do what you want to achieve with one array-to-pointer and one pointer-to-array casting like;

// ... your includes
#include <stdlib.h>
// ... your defines
#define MAX_LEN 100
// ... your codes
// I assume there is no any defined TCHAR array to be converted so far, so I'll create one
TCHAR c_wText[MAX_LEN] = _T("Hello world!");
// Now defining the char pointer to be a buffer for wcstomb/wcstombs
char c_szText[MAX_LEN];
wcstombs(c_szText, c_wText, wcslen(c_wText) + 1);
// ... and you're free to use your char array, c_szText

PS: Could not be the best solution but at least it's working and functional.

Answer 2

TCHAR is a Microsoft-specific typedef for either char or wchar_t (a wide character).

Conversion to char depends on which of these it actually is. If TCHAR is actually a char, then you can do a simple cast, but if it is truly a wchar_t, you'll need a routine to convert between character sets. See the function MultiByteToWideChar().

I think we need to convert from wchar_t to char so we need WidecharToMultiByte!! – Pompous

Answer 3

Why not just use wcstombs_s ?

Here is the code to show how simple it is.

#define MAX_LENGTH 500
...

TCHAR szWideString[MAX_LENGTH];
char szString[MAX_LENGTH];
size_t nNumCharConverted;
wcstombs_s(&nNumCharConverted, szString, MAX_LENGTH,
        szWideString, MAX_LENGTH);

You misspelled 'LENGTH'. – Criticism

LENGHT is a constant not a keyword. – Enthral

Done, I fixed LENGTH spelling. – Acosmism

Answer 4

It depends on the character set (Unicode or ANSI) (wchar_t or char), so if you are using ANSI simply TCHAR will be char without any casting, but for Unicode, you have to convert from wchar_t to char, you can use WideCharToMultiByte
