Hi!

Well, I see a couple of differences from what I know.

First of all, boundary is much longer in the packet that IE sends to WEB server. Another difference is that you add too many line breaks. There is not line break between starting boundary and binary data, as far as I remember.

Just for you information: If neded, I can send you a sample of HTTP packed data for multipart/data POST. I have an ASP application program that grabs the binary input from WEB server dusring multipart/data POST, parses it and stores binary fiel properly. I did not used any DLL for this. ASP is slow, so I get it to work only for files with length up to 2.5 MB. I can debug it and strip out the converted output so you will see a format used here.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
