The server script that handles the upload should expect a POST request with the following elements:. If the testUpload parameter is true , and the file to be uploaded is bigger than approximately 10 KB, Flash Player on Windows first sends a test upload POST operation with zero content before uploading the actual file, to verify that the transmission is likely to succeed.
Note : If your server requires user authentication, only SWF files running in a browser — that is, using the browser plug-in or ActiveX control — can provide a dialog box to prompt the user for a username and password for authentication, and only for downloads. However, in Adobe AIR, content in the application security sandbox content installed with the AIR application are not restricted by these security limitations.
Initiate uploading a file to a URL without any encoding. Whereas the upload method encodes the file in a form-data envelope, the uploadUnencoded method passes the file contents as-is in the HTTP request body.
Use the uploadUnencoded method if the data you wish to send is already encoded in a format that the receiving server can understand.
Dispatched when a file upload or download is canceled through the file-browsing dialog box by the user. Flash Player does not dispatch this event if the user cancels an upload or download through other means closing the browser or stopping the current application. Dispatched when download is complete or when upload generates an HTTP status code of For file download, this event is dispatched when Flash Player or Adobe AIR finishes downloading the entire file to disk.
Dispatched if a call to the upload or uploadUnencoded method attempts to access data over HTTP and Adobe AIR is able to detect and return the status code for the request. Dispatched when an upload fails and an HTTP status code is available to describe the failure. The httpStatus event is dispatched, followed by an ioError event.
The httpStatus event is dispatched only for upload failures. For content running in Flash Player this event is not applicable for download failures. Dispatched when the upload or download fails.
The SWF file tries to upload a file to a server that requires authentication such as a user name and password. If a SWF file tries to upload a file to a server that requires authentication, the upload fails. The SWF file tries to download a file from a server that requires authentication, within the stand-alone or external player.
During download, the stand-alone and external players do not provide a means for users to enter passwords. If a SWF file in these players tries to download a file from a server that requires authentication, the download fails.
The value passed to the url parameter in the upload method contains an invalid protocol. Important: Only applications running in a browser — that is, using the browser plug-in or ActiveX control — and content running in Adobe AIR can provide a dialog box to prompt the user to enter a user name and password for authentication, and then only for downloads.
For uploads using the plug-in or ActiveX control version of Flash Player, or for upload or download using either the stand-alone or the external player, the file transfer fails. Dispatched when the application requests permission to access filesystem. Check the value of status property to determine whether the permission was granted or denied. Dispatched periodically during the file upload or download operation.
The progress event is dispatched while Flash Player transmits bytes to a server, and it is periodically dispatched during the transmission, even if the transmission is ultimately not successful.
To determine if and when the file transmission is actually successful and complete, listen for the complete event.
In some cases, progress events are not received. For example, when the file being transmitted is very small or the upload or download happens very quickly a progress event might not be dispatched. File upload progress cannot be determined on Macintosh platforms earlier than OS X The progress event is called during the upload operation, but the value of the bytesLoaded property of the progress event is -1, indicating that the progress cannot be determined.
Dispatched when a call to the FileReference. The value of the text property that describes the specific error that occurred is normally "securitySandboxError".
You can try to remedy this error by using a URL policy file. In Adobe AIR, these security restrictions do not apply to content in the application security sandbox.
Dispatched when the user selects a file for upload or download from the file-browsing dialog box. This dialog box opens when you call the FileReference. When the user selects a file and confirms the operation for example, by clicking OK , the properties of the FileReference object are populated.
For content running in Flash Player or outside of the application security sandbox in the Adobe AIR runtime , the select event acts slightly differently depending on what method invokes it. When the select event is dispatched after a browse call, Flash Player or the AIR application can read all the FileReference object's properties, because the file selected by the user is on the local file system.
When the select event occurs after a download call, Flash Player or the AIR application can read only the name property, because the file hasn't yet been downloaded to the local file system at the moment the select event is dispatched. When the file is downloaded and the complete event dispatched, Flash Player or the AIR application can read all other properties of the FileReference object. Dispatched after data is received from the server after a successful upload. This event is not dispatched if data is not returned from the server.
Note: To run this example, change the uploadURL. Based on your configuration, you might also need to compile the SWF file with Local Playback Security set to Access Network Only or to update Flash Player security settings to allow this file network access.
Filters: Retrieving Data from Server Retrieving Data from Server Classes x. Package flash. An operating-system dialog box prompts the user to select a file to upload or a location for download. Each FileReference object refers to a single file on the user's disk and has properties that contain information about the file's size, type, name, creation date, modification date, and creator type Macintosh only.

Checks whether the EventDispatcher object has any listeners registered for a specific type of event. Indicates whether an object has a specified property defined. Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter.
Indicates whether the specified property exists and is enumerable. Sets the availability of a dynamic property for loop operations. Returns the string representation of this object, formatted according to locale-specific conventions.

Implementation public function get data : ByteArray Throws IllegalOperationError — If the load method was not called successfully, an exception is thrown with a message indicating that functions were called in the incorrect sequence or an earlier call was unsuccessful.
In this case, the value of the data property is null. Implementation public function get extension : String Throws IllegalOperationError — If the reference is not initialized. In this case, the value of the modificationDate property is null. In this case, the value of the type property is null.
Returns Boolean — Returns true if the parameters are valid and the file-browsing dialog box opens. Events select : Event — Dispatched when the user successfully selects an item from the Browse file chooser.
Throws IllegalOperationError — Thrown in the following situations: 1 Another FileReference or FileReferenceList browse session is in progress; only one file browsing session may be performed at a time.
ArgumentError — If the typeFilter array contains FileFilter objects that are incorrectly formatted, an exception is thrown. For information on the correct format for FileFilter objects, see the FileFilter class. Error — If the method is not called in response to a user action, such as a mouse event or keypress event. When you use this method , consider the Flash Player security model: Loading operations are not allowed if the calling SWF file is in an untrusted local sandbox.
The default behavior is to deny access between sandboxes. A website can enable access to a resource by adding a URL policy file.
When you download a file using this method, it is flagged as downloaded on operating systems that flag downloaded files: Windows XP service pack 2 and later, and on Windows Vista Mac OS Events open : Event — Dispatched when a download operation starts. You could do this by simply constructing a new XML object that contains those values, then read those values back out of the XML object.
