ASCII string to UNICODE string

Question

Hi,
I need to convert a simple word from ASCII to UNICODE.
I am using VC++ 6.0 and was wondering if i can make it so that when I type "hello" the compiler will automatically change it into UNICODE, instead of having to use the MultibyteToWideChar() function.
Also i am unsure how to use this function(how should i declare the buffer the converted string is stored in) Could someone please show me an example.
Thanks

Answer 1

u can build the app in unicode and accept the input in a CString (in unicode the CString::m_pchData will be of type WCHAR*)

u can use  the function as...

MultiByteToWideChar(CP_ACP, 0, GetName() /*returns CString object*/, 
       GetName().GetLength() + 1,
       m_wzCharFile /* WCHAR* datatype */, MAX_PATH);

Regards,

  Sudeesh.

If you want to type "hello" into your program and ask the compiler to represent it in Unicode, then use the "L" suffix. For example:

 

wchar_t unicodeString[] = L"hello";

 

I hope this helps.

Answer 4

you can also use A2W (ATL conversion macros) for conversion.
CString will allocate memory with wchar_t if UNICODE specified else it will be char*

int MultiByteToWideChar(
  CP_ACP, // code page
  MB_PRECOMPOSED// character-type options
  pChInput,  // string to map
  nSizeInput, // number of bytes in string
  pWchDest,  // wide-character buffer
  nSizeDest // size of buffer
);

Perfect thanks

Answer 6

_T() would be good choice than L"";
because it will behave depends on the UNICODE definition
