char* conversion into LPCTSTR

    Const Char* dibfilename;     int num = MultiByteToWideChar (00, Dibfilename,-10);     New Wchar_t[num];    MultiByteToWideChar (00, Dibfilename,-1, wide, num);

    Char m_filename[];     // this is possible in multibyte or Unicode mode.      _bstr_t bstrtmp (m_filename);     = (LPTSTR) bstrtmp;

parsing:

Num Gets the space required for long bytes
MultiByteToWideChar () means that the characters in s are passed to the memory that the PS points to. 1 indicates the transfer to ' + ' in S, Num represents the number of bytes passed.

char* conversion into CString

    // char *-->cstring     // Outputfilepath = "G:\\testdll"    Const Char* Outputfilepath;    CString str1 (outputfilepath);

CString conversion into char*

Char*Cdib::cstringtochararray (CString str) {Char*ptr; #ifdef _unicode LONG Len; Len= WideCharToMultiByte (CP_ACP,0, str,-1Null0, NULL, NULL); PTR=New Char[Len +1]; Memset (PTR,0, Len +1); WideCharToMultiByte (CP_ACP,0, str,-1, PTR, Len +1, NULL, NULL);#elseptr=New Char[Str. Getalloclength () +1]; sprintf (PTR, _t ("%s"), str);#endif    returnptr;}
