WINCE很好用的字符转换函数

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。 //=============================== #pragma once #include "afxwin.h" #include <string> //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 string UnicodeToANSI( const wstring& str ) { char* pElementText; int iTextLen; // wide char to multi char iTextLen = WideCharToMultiByte( CP_ACP, 0, str.c_str(), -1, NULL, 0, NULL, NULL ); pElementText = new char[iTextLen + 1]; memset( ( void* )pElementText, 0, sizeof( char ) * ( iTextLen + 1 ) ); ::WideCharToMultiByte( CP_ACP, 0, str.c_str(), -1, pElementText, iTextLen, NULL, NULL ); string strText; strText = pElementText; delete[] pElementText; return strText; } //UTF-8 to Unicode wstring UTF8ToUnicode( const string& str ) { int len = 0; len = str.length(); int unicodeLen = ::MultiByteToWideChar( CP_UTF8, 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_UTF8, 0, str.c_str(), -1, (LPWSTR)pUnicode, unicodeLen ); wstring rt; rt = ( wchar_t* )pUnicode; delete pUnicode; return rt; } //Unicode to UTF-8 string UnicodeToUTF8( const wstring& str ) { char* pElementText; int iTextLen; // wide char to multi char iTextLen = WideCharToMultiByte( CP_UTF8, 0, str.c_str(), -1, NULL, 0, NULL, NULL ); pElementText = new char[iTextLen + 1]; memset( ( void* )pElementText, 0, sizeof( char ) * ( iTextLen + 1 ) ); ::WideCharToMultiByte( CP_UTF8, 0, str.c_str(), -1, pElementText, iTextLen, NULL, NULL ); string strText; strText = pElementText; delete[] pElementText; return strText; |
