• Is there a way to get a mobile Safari WebApp to "forget" its state?

  - by Alex Mcp

  I have a nascent bridge scoring app that is meant to be stored locally on an iPod touch/iPhone (iPad? Would probably be fugly...) So far so good, got a custom icon rolling and basic JS navigation laid out, but my problem is that it retains its state when I quit the app. Is there a simple magic Apple meta tag for this? Or is it achieved with javascript? Thanks for any insight.

• Why membership provider is not generic?

  - by Timmy O' Tool

The default implementation is not very appropriate normally and I haven't seen so far a good implementation of a custom membership provider, probably because this is not possible :-) So the question is: In your opinion: which are the reasons for not having membership/role provider as a generic class? I mean, why Microsoft didn't selected this approach.

  - by dvg

  I have a NSTableView that contains a NSButtonCell in one of the columns.

• How can I trigger a transition effect when a child control is added or removed in flex?

  - by Jason Towne

  I've got a custom component that has children components dynamically added and removed to it depending on what button the user clicks.

• How can I create a Zerofilled value using JavaScript?

  What is the recommended way to zerofill a value in JavaScript? I imagine I could build a custom function to pad zeros on to a typecasted value, but I'm wondering if there is a more direct way to do this? Note: By "zerofilled" I mean it in the database sense of the word (where a 6-digit zerofilled representation of the number 5 would be "000005").

• How to justify text on a TextView made easy- Android

  - by Juan

  I'm looking for a simple way to forget that I'm using a WebView to have justified text in my TextView. Has someone made a custom view for this? I'm well aware that I can do something like this: WebView view = new WebView(this); view.loadData("my html with text justification","text/html","utf-8"); But it gets ugly when you want to set the size, the color or other common properties of the TextView, there must be a more convenient way of doing it.
