I have been trying Xsendfile() method in Yii over 20 times and none of them gave me a result. Here is my code:

    $file_path = "D:/xampp/htdocs/mywebapp/protected/modules/file_upload".DS.
                  'views'.DS.'upload'.DS.testfile.".pdf"; 
    Yii::app()->request->xSendFile($file_path ,array(
       'saveName'=>$result['gen_name'] .".pdf",
       'mimeType'=>'application/pdf',
       'terminate'=>true,
     ));

And despite changing the location of testfile.pdf everywhere on my hard drive, none of them works. I am nearly exhausted with this method. Anyone could help me from being headache? I am using windows and xampp 1.7.4. Thanks so much!
