• Ruby Win32Api get single character non-blocking

  - by Markus Orreilly

  I'm trying to write a simple game working with two threads, one thread to get input from the user, and another thread to animate some scenes. I'm able to get characters without pressing ENTER just fine, but it blocks in the animating thread until the user presses a key. Does anyone know of a way to get a character from the keyboard non-blocking?

• Is there a view for inputing integers in Android?

  - by J. Pablo Fernández

  I'm looking for something like the individual parts of the date picker dialog. A view that allows you to input integers (and only integers) that you can limit (between 1 and 10 for example), where you can use the keyboard or the arrows in the view itself. Does it exists? It is for a dialog. A ready-made dialog to request an integer would also help.

• How can I add a column to this union result?

  - by MrXexxed

  I have this query (which I removed some keys from for brevity's sake): SELECT id as in_id, out_id, recipient, sender, read_flag FROM received WHERE recipient=1 UNION ALL SELECT in_id, id AS out_id, recipient, sender, read_flag FROM sent WHERE sender=1 Which combines the results from two tables showing messages sent and received by a given user. What I'd like to do is add a column/flag to the result to distinguish which table the row belongs to so when I display them I can show a relevant icon for sent or received messages. How would I add this?
