• Hi,

    I have an issue. If I include wide characters (wchar_t) to the second parameter to CHttpFile::SendRequest() , the subsequent call  to CHttpFile::Read() does not succeed.

    For the wchar_t data , I use casting something as (LPVOID)(LPCTSR)

    Code is something as follows.

    CString p_strHeaders = _T("Content-Type: application/x-www-form-urlencoded\r\n\r\n");


       (LPVOID)pTotal, dwHeaderSize + dwFileSize + dwFooterSize);

    where pTotal is BYTE*

    nBytesRead = m_pFile1->Read(buffer, MAXBUF - 1); 

    My requirement is to upload file containing wide character data (Japanese characters) to the server. How can I pass wide characters in the second parameters?

  • Well, if content type is "url encoded" then you have to url encode. Also, the web pretty much uses utf-8, not utf-16 which is implied by wchar_t.

    So you first have to convert the string to utf-8 by using something like WideCharToMultiByte with codepage = CP_UTF8 and then url encode (see the utf-8 string.
