Hello,

I have a program I am developing with curl but am having troubles
uploading a file.

These are the steps I am currently taking in my program. I would
appreciate if anyone could point out any thing I am doing wrong.

OS: WinXP
Curl Version: 7.11.1
IDE: Visual C++ .NET

        char m_szErrMsgLast[1024];
        FILE *pInput = fopen(szLocalFile, "r"); // Open the local file
(C:\tmp.txt would suffice here)
        if (NULL == pInput)
                throw "Unable to open local file";
        long fsize = filelength(fileno (pInput));

        curl_global_init(CURL_GLOBAL_ALL);

        void * m_pCurl = curl_easy_init();

        // set the errror buffer
        curl_easy_setopt(m_pCurl, CURLOPT_ERRORBUFFER, m_szErrMsgLast);

        //Set the passive mode
        curl_easy_setopt(m_pCurl, CURLOPT_FTP_USE_EPSV, TRUE);

        // enable uploading
        curl_easy_setopt(m_pCurl, CURLOPT_UPLOAD, TRUE) ;

        // Set the URL to transmit to (the value of this is
remotefile.txt)
        curl_easy_setopt(m_pCurl, CURLOPT_URL, szRemoteFile);

        // Set a pointer to the file to be sent, and set the size
        curl_easy_setopt(m_pCurl, CURLOPT_INFILE, pInput);
      curl_easy_setopt(m_pCurl, CURLOPT_INFILESIZE, fsize);

        // Want to watch what happens!
        curl_easy_setopt(m_pCurl, CURLOPT_VERBOSE, TRUE);
 
        // Fire away!
        res = curl_easy_perform(m_pCurl);

What results is a crash in curl. The curl_easy_preform call at the end
throws an exception:
(I replaced any identifying information with garbage numbers, but the
messages are untouched.

* About to connect() to 111.22.33.44 port 21

This pauses for a while, I assume the file transfer attempts to take
place.

Then the excetion is thrown:

+ ex { _COMPlusExceptionCode=-532459699
_className="System.NullReferenceException" _exceptionMethod=<undefined
value> ...} System.Exception
+ "System.NullReferenceException: Object reference not set to an
instance of an object.

Any advice at all as to what I may be doing wrone here would be GREATLY
appreciated!

Cheers,
joe
