A very nice section under windows programming..
Every windows programmer may deals with UNICODE, ANSI like character encoding schemes..
And also, the conversion from Unicode to ANSI and vice versa..
Now I collect some stuffs for you..
Converting UNICODE string to ANSI strings..
You can convert a Unicode string to an ANSI string with the WideCharToMultiByte() API
The syntax is
int WideCharToMultiByte(
UINT CodePage,
DWORD dwFlags,
LPCWSTR lpWideCharStr,
int cchWideChar,
LPSTR lpMultiByteStr,
int cbMultiByte,
LPCSTR lpDefaultChar,
LPBOOL lpUsedDefaultChar
);
For example, we have our UNICODE string in wszUNICODEString, we want to convert that to ANSI string szANSIString.
char szANSIString [MAX_PATH];
WideCharToMultiByte ( CP_ACP,                // ANSI code page
WC_COMPOSITECHECK,     // Check for accented characters
wszUNICODEString,         // Source Unicode string
-1,                    // -1 means string is zero-terminated
szANSIString,          // Destination char string
sizeof(szANSIString),  // Size of buffer
NULL,                  // No default character
NULL );                // Don’t care about this flag
wcstombs()
Converts a sequence of wide characters to a corresponding sequence of multibyte characters.
Syntax is just
size_t wcstombs_s(
char *mbstr,
const wchar_t *wcstr,
size_t count
);
For eg:  wcstombs_s ( szANSIString, wszUNICODEString, sizeof(szANSIString) );
CString
Using CString class’s constructors and assignment  operators, we can convert UNICODE string to ANSI string.
Using constructor
CString strANSI_1 (wszUNICODEString);
Using Assignment Operator
CString strANSI_2;
strANSI_2 = wszUNICODEString;
ATL macros
To convert a Unicode string to ANSI, use the W2A() macro
#include <atlconv.h>
….
{
char szANSIString [MAX_PATH];
USES_CONVERSION;  // DeclareA very nice section under windows programming..

Make the best of lifes moments !!

What really matters at the end of the day is if you made the best use of time,
and done everything that you needed to do.

Don’t sit just there waiting, You only live once!
