how to add 0 to a string
hi,
i'm still trying to send an xml-style sting via tcp to another app... ie: NetAddr("bla",12345).sendRaw("<xlmString />") to terminate the sting it has to be ended with a binary 0. but somehow sc seems to ignore all 0s:
("some string" ++ 0.asAscii).ascii returns [ 115, 111, 109, 101, 32, 115, 116, 114, 105, 110, 103 ] ("some string" ++ 54.asAscii).ascii returns [ 115, 111, 109, 101, 32, 115, 116, 114, 105, 110, 103, 54 ] ("some string" ++ 0).ascii gives me the 0's ascii value [ 115, 111, 109, 101, 32, 115, 116, 114, 105, 110, 103, 48 ]
is there any way to add the binary zero, and use it with NetAddr.sendRaw? or is it possible to use integers as ascii-values and change them back into a string (the opposite of .asAscii).
thanks, florian

Re: how to add 0 to a string
Something like this:
("some string".ascii ++ 0).collectAs(_.asAscii, String).ascii [ 115, 111, 109, 101, 32, 115, 116, 114, 105, 110, 103, 0 ]
