  Hi, I do have two buttons 'btnPrev' and 'btnNext' What I want to do is to be able to determine the number of clicks of the button so that I could enable and disable them.

There is the method extFilter = FileNameExtensionFilter(description, extensions); that I can then use by writing fileChooser.setFileFilter(extFilter); however, as you can see, this only supports one option in the drop-down list. How do I add more?

• What good alternatives are there to Google Charts?

  - by Rhubarb

  I have been experimenting with Google charts. Are there any alternatives that are reasonably as expressive but can be installed locally on your own web server?

Any clues?

  I have created a turing-complete programming language (already proven) so it must be possible to write a quine for it, right? But all quines I know store their source code in a string and then replace a special character in it using something like chr and ord. My language only has the following Basic arithmetics Int and string types Variables == operator Conditional gotos I have no idea how I could write a quine as I have no real string manipulation available, I can only output constant strings. Yet, it is 100% turing-complete.
