Thanks for the replys gentlemen, they were a great help. I now have something which does what it is supposed to, so its on to stage 2.
The first time I heard of a callback was when Stan mentioned it in his post. After much research and experimentation I can move on. All those books about
java apparently teach you only how to write code, not programs.
So thanks again, and expect more questions.
BTW, Stan I looked into your sig line- very cool stuff.
