Help with code...
I want to have the user enter encrypted text in a text box then click a button to view it unencrypted.
Assume
#1: user already has the encrypted text
#2 The text needs to be unencrypted by the following
Public String decode(String s)
{
byte byte0 = 20
s = s.trim();
int j = s.length();
char ac[] = s.toCharArray();
for(int i = 0; i < j; i++)
{
int k = ac[i] - byte0;
if(k < 32)
ac[i] = (char) (95 + k);
else
ac[i] = (char)k;
}
String s1 = new String(ac);
return s1;
}

return s1;
}
What exactly is your question? Do you want an example of this being done in a command line situation?

I need the HTML to make it happen...
oh, so this is an applet, then, correct?
when you embedd the applet, give it a name
<APPLET name="myapplet"> or something
make sure your decode method is public, and
write a little script that calls it from the html side
<script language="javascript">
function decode(inputfield) {
var encodedstring=inputfield.v
var decodedform=inputfield.for
var decodedstring=document.mya
decodedform.value=decodeds
}
</script>
then you can have a text box like so
<form method="get" action="#">
<input type="text" name="encoded">
<input onclick="decode(this);" type="button" value="decode"><br />
Decoded: <input name="decoded" type="text"><br />
</form>
That's the rought idea, try it out.. hope it helps
I heard that there was a limiation on the IE MAC's jvm that doesn't allow scripting applets, you might want to make sure.
