OK, so I modified the code a litte bit:

        Int c_formadd = 0;
      c_formadd = curl_formadd(&opost, &olast,
        CURLFORM_COPYNAME, "sendfile",
        CURLFORM_FILE, "c:\\test.jpg",
        CURLFORM_END);

      c_formadd = curl_formadd(&opost,
         &olast,
         CURLFORM_COPYNAME, "filename",
         CURLFORM_COPYCONTENTS, "test.jpg",
         CURLFORM_END);
I added an extra \ to the CURLFORM_FILE and also set a name and added an
extra curl_formadd() for a field that contains the filename. When I
execute the code both curl_formadd() returns 0, but it still looks like
the server
never receives the file.

Any ideas?

This only sets the content of this part, not the name. I think you have
to set the name for the part for it to work. Did you check the return
code from curl_formadd()?

Compare with this (working) example:
