File download help required

[eluser]Computerzworld[/eluser]
I have slightly changed my code and now I am getting file contents in new window. But the file doesn't download. Here is the modifictation that I have made.

Code:

function forceDownload()
    {
        $this->load->helper('download');
        $data = file_get_contents(base_url().'/uploads/files/admin_uploadedFile/'.$this->fileName); //<-- change in code
        $name = $this->fileName;        

        force_download($name, $data);
        }
