File upload problem

31
hi all,
My problem is that I want to upload a file without asking the user to select the file as I know the location of the file on the users machine.

The whole process goes like this,
User will invoke scanner from javascript and when the scanning was done
user will get an Upload button, when user clicks on that upload button the file should be uploaded to the server.

Able to invoke scanner and also saving file was done on clients machine but, not able to do file upload automatically.
Is there any way to do it????

regards
Nelluru

you can simply read the data of a file input in firefox, no about:config hacking and xpconnect involved. every file input has a files property, an array of files. each value has a toDataURL method, as well as getAsBinary().

Sorry Forgot to mention that I have to read binary files for Internet Explorer not for Firefox
