• MySQL using function IN with variable

  - by misanov

  I have problem querying table with variable in IN function. SELECT s.date, (SELECT GROUP_CONCAT(value) FROM value WHERE id_value IN(s.ref_values) ) AS vals FROM stats s ORDER BY s.date DESC LIMIT 1 Where s.ref_values is '12,22,54,15'. I get only one return for first number (12). When I insert that value directly in IN(12,22,54,15) it finds all 4. So, there must be problem with using variable in IN. What am I doing wrong?

• Android - Add other values to websettings settextsize

  - by user1681477

  In my application I am using a webview, and in order to increase/decrease text size, I am using WebSettings().setTextSize method, but, this method is limited to 5 predefined enum sizes only (SMALLEST, SMALLER, NORMAL, LARGER,LARGEST). I know I can use WebSettings().setTextZoom(int), but my application is available for API Level 8 and above, and this method was introduced in API Level 14... My question is: Is there any way to add other sizes to webSettings().setTextSize? maybe by extending textSize enum, or define other sizes?

• Why does refreshing a page with a google map often fail?

  - by Shawn

  I'm working on a website that needs google maps, and testing is being a bitch because refreshing the page very often fails (hangs endlessly) so I need to go to a different page and come back in order to test the new version of the code. I have noticed that refreshing the page only fails on pages with maps, so I'm guessing these are related. Does anyone have a clue?
