Question

in the following code :

var benq:Base64Encoder = new Base64Encoder(); benq.encode('force',0,5); var tmp:String = benq.toString(); 

‘tmp’ turns out to be an empty string, i.e. with length 0. why? how to encode a string using base64encoder?

Answer 1

Are you sure that your code isn’t working. I just copied and pasted it into a test app and it returned tmp as ‘Zm9yY2U=’

Are you doing anything else to the var tmp? if debugging make sure that it has processed the var tmp:String…. line when your checking the output
