As with most questions the answer is yes and no.
In an intranet application, where the browsers security settings allow access to the user's drive, then you can read a file, embed the data as base 64 encoded binary into an XML file. We had an application like this at my last company.

For examples of doing this search the forums for posts by joefawcett with adodb.stream in the message.

The disadvantage is that large files get very large when encoded.

Alternatively you can just use the standard input, type=file, control to upload with the user's acceptance and maybe post some extra information back via Ajax as well.

Thnx imformation joefawcett,

I'll have a go to try this method. The thing is that this method would be very handy to use with a cms.

I solved this in an application of mine by posting the form containing the file input field to a hidden iframe. It gives the impression of being AJAX, while it's just a standard file input that's posting to a hidden frame.

Rich

Hello to all,
   can u please tell me how to do upload files with iframe.i want upload process something like GMAIL.i m using Majix:Ajax Panel in my Page..


Please Help Me.....

Hi panchalvimal

Place a hidden IFrame in your main page and load an HTML form, containing upload control on it. When user wants to select a file, call 'click()' method of your file upload control that exists in hidden iframe from your container page. This would bring a choose file dialog so that user can select a file.

After that, when you want to start uploading, call 'submit()' method of form element from your container page. This will starts uploading HTML page, contained in hidden iframe. When upload completes, your response would be placed in hidden iframe. You should place upladed file in a temporary location (like user session or a temporary folder on your server) and generate an appropriate javascript code on your response, so that when response loads completely on your client page, makes a call to container and inform it about upload completion.

Goodluck
