Hiii..
I am also facing a similar problem.
My Problem :
I want the user to select one particular file, and the rest of the
files of similar formats should be uploaded automatically.without user
selecting them. I know that we cant assign value to the file control.
So I created ActiveX Object WScript.Shell. object and used the method
sendkeys() to write the path of the file to a hidden file control. Now
I was able to upload a 100 file together when the client and server
were in the same domain.
Now, My server will reside in different domain,. so the IE which
accesses the server is not allowing the form to get submitted.

I hope I have been clear in expressing the problem,
Hoping for a quick reply.
Thanks in Advance.
