Not enough information here. Where does your flash application live? Is it on another server than Drupal? On the desktop? Or on the same server? Is it being served from within Drupal? or is it a separate application? How do you want the file uploaded? Does it need to be attached to a node, or otherwise processed using the drupal api? Or does it simply need to get dumped into a server directory?
In general, your best option for interfacing a flash application with the drupal api is via a webservice (xmlrpc, soap). You can have your flash application authenticate to the drupal webservice and have it access exposed methods to upload your file. If you need to create a node with the file attached, you could pull that off, too.
Depending on what you want to do, you may need to write a module or extend an existing one to implement the necessary services hooks.

I can upload a file to web server without user interaction? i mean, no dialog asking the user the file for upload!
