ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

Note: If both "read" and "write" are set, "readWrite" is automatically set. The user or process owner that the server

runs under in the operating system must have write permissions to use “create”, “append”, “readWrite”, and “write”

modes.

Returns

A boolean value indicating whether the file opened successfully (

true) or not (false).

Example

The following client-side script creates a connection to an application called file:

var nc:NetConnection = new NetConnection();

function traceStatus(info) {

trace("Level: " + info.level + " Code: " + info.code);

}

nc.onStatus = traceStatus;

nc.connect("rtmp:/file");

The following server-side script creates a text file called log.txt and writes text to the file:

application.onConnect = function(client){

this.acceptConnection(client);

var logFile = new File("log.txt");

if(!logFile.exists){

logFile.open("text", "append");

logFile.write("something", "somethingElse")

}

};

File.position

fileObject.position

The current offset in the file. This is the only property of the File class that can be set. Setting this property performs

a seek operation on the file. The property is undefined for closed files.

Availability

Flash Media Server 2

File.read()

fileObject.read(numChars)

Reads the specified number of characters from a file and returns a string. If the file is opened in binary mode, the

operation fails. When this method fails, it invokes the

application.onStatus() event handler to report errors.

Value Description

"read" Opens a file for reading.

"write" Opens a file for writing.

"readWrite" Opens a file for both reading and writing.

"append" Opens a file for writing and positions the file pointer at the end of the file when you attempt to write

to the file.

"create" Creates a new file if the file is not present. If a file exists, its contents are destroyed and a new file is

created.
