• Can we turn on the iphone's number keyboard WITHOUT using type=number?

  - by Simple As Could Be

  I'm making a webapp, and I'd like an input field to show the Iphone's number keypad. I understand that type=number will make the keypad show the way I'd like. The trouble is that type=number does not support placeholder text. So if I would like this: Expiration Date: [eg: 2010] I can not get it to work, and also show the right keyboard. Is there a way to force the iphone keyboard into number mode without using the number input type?

• Webview blank but content is there

  - by Scott Dugas

  I am having trouble displaying a webview. I have a webview inside a custom view. I load this custom view as a subview of the window, and then have an object controller linking a text field to the content of the web view. Once a page is loaded, it loads all the content, but it is visually white. You can click on links. If you go to a Youtube video you can listen to it, but it still displays nothing.

• Stored Procedure in postgresql, multiple queries w/ agreggates.

  - by fenix

  I'm trying to write a store procedure that can take some input parameters (obviously), run multiple queries against those, taking the output from those and doing calculations, and from those calculations and the original queries, outputting a formatted text string like: Number of Rows for max(Z) matching condition x and y of total rows matching x (x&y/x*100). To explain the max(Z) bit, this will be the username field, it won't matter which actual entry is picked, because the where clause will filter the results by user id, is there a saner way to do this?
