WINCE很好用的字符转换函数

2008-07-27 16:15

在WINCE 下，是使用Unicode编码的，对PC的接口，都要转换一下，才能用。
把以下复制成 *.h文件，加入到工程中，即可。

//ANSI to Unicode
wstring ANSIToUnicode( const string& str )

{

int len = 0;

len = str.length();

int unicodeLen = ::MultiByteToWideChar( CP_ACP,

0,

str.c_str(),

-1,

NULL,

0 );

wchar_t * pUnicode;

pUnicode = new wchar_t[unicodeLen+1];

memset(pUnicode,0,(unicodeLen+1)*sizeof(wchar_t));

::MultiByteToWideChar( CP_ACP,

0,

str.c_str(),

-1,

(LPWSTR)pUnicode,

unicodeLen );


wstring rt;

rt = ( wchar_t* )pUnicode;

delete pUnicode;



return rt;

}

//Unicode to ANSI
