FileReference (flash.net.FileReference) 567
Returns
Boolean - A value of true if the dialog box in which a user can select a file is displayed. If the
dialog box is not displayed, the method returns
false. The dialog box could fail to be
displayed for any of the following reasons:
■ You did not pass a value for the url parameter.
■ The parameters passed are of the incorrect type or format.
■ The url parameter has a length of 0.
■ A security violation occurred; that is, your SWF file attempted to access a file from a server
that is outside your SWF file's security sandbox.
■ Another browse session is already in progress. A browse session can be started by
FileReference.browse(), FileReferenceList.browse(), or
FileReference.download().
■ The protocol is not HTTP or HTTPS.
