File uploading via the Internet is used in many applications such as conference organization and virtual accounts directory. To submit text data to web server is relatively easy. However, to submit binary data, such as pictures, PDF file, Excel Charts or documents written in Microsoft Word, to web server seems is not as easy.
             In this paper, we discuss the principles of designing COM ActiveX component and Java Bean, which can be used in ASP and JSP respectively for binary file uploading. We also discuss how to use C program and XML WSC method to do binary file uploading.
             We compare the five methods of uploading binary files using varies file sizes. There are no significant differences in transmission speed except the XML WSC methods. We also compare our COM method with three Commercial products. Our program ismore flexible in many aspects. For example, our program can return a file pointer from COM to ASP, so that we can easily set up database in ASP. Aslo our program is about 1/5 faster for uploading images to DBMS.
