1、将单字节Char转化为双字节的wchar_t的转换函数
wchar_t* c2w(const char *str) { int length = strlen(str)+1; wchar_t *t = (wchar_t*)malloc(sizeof(wchar_t)*length); memset(t,0,length*sizeof(wchar_t)); MultiByteToWideChar(CP_ACP,0,str,strlen(str),t,length); return t; }
//将单字节char*转化为宽字节wchar_t* wchar_t* AnsiToUnicode( const char* szStr ) { int nLen = MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, szStr, -1, NULL, 0 ); if (nLen == 0) { return NULL; } wchar_t* pResult = new wchar_t[nLen]; MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, szStr, -1, pResult, nLen ); return pResult; }
//将宽字节wchar_t*转化为单字节char* inline char* UnicodeToAnsi( const wchar_t* szStr ) { int nLen = WideCharToMultiByte( CP_ACP, 0, szStr, -1, NULL, 0, NULL, NULL ); if (nLen == 0) { return NULL; } char* pResult = new char[nLen]; WideCharToMultiByte( CP_ACP, 0, szStr, -1, pResult, nLen, NULL, NULL ); return pResult; }
2、char[] 转换为 LPWSTR
解决方案:
思路一: 使用CA2W字符转换宏(ATL and MFC String Conversion Macros)。 根据MSDN描述,这个宏用于将ANSI转换为Wide Character(UNICODE)
代码如下: LPWSTR aaa = CA2W(text); item.pszText = aaa;
思路二: 使用int MultiByteToWideChar()函数。根据MSDN描述,这个方法:This function maps a character string to a wide-character (Unicode) string。
代码如下:
TCHAR aaa[31]; MultiByteToWideChar(0,0,text,31,aaa,62);
