Hi Gamestar -
Think you're right, its not possible to write directly to files from an
applet, but it is ok within a java application;
I have some code below that I tried in my applet, also gave the
'SecurityException' (or was it FileIOException?). So never got it to work;
try it in an application; there's probably other bugs, but at leat this is a
start ;-)
static public void diskout (String s)
{
DataOutput oput = null;
try {
oput = new DataOutputStream( new FileOutputStream("C:\testout") );
} catch (IOException e) {
alert("couldn't create file output stream");
}
if (oput != null) {
try {
oput.writeBytes(s.toString() );
} catch (IOException e) {
alert("couldn't write to file");
} finally {
// oput.close();
}
}
}
'alert' basically brings up a dialog box, but that's another hack/story.
