问题 I have a Javascript Windows Store Application that hosts an iframe. The webpage inside of my iframe is not aware of my app, so it doesn't have any PostMessage interface to my app. The iframe will set a cookie when I 'log in' in the iframe.

(i.e. I can change the webpage in the iframe) Do I use PostMessage? 回答1: You can use PostMessage that your

问题 I want to update my UI based on the scenario when an Ad is being shown or an error occurred. I am using AdRotator v2.1.

I change it in order to highlight the selected item, like this: <local:AlternateConverter CurrentList="{Binding ElementName=myList, Path=ItemsSource}" HighlightIndex="{Binding ElementName=myList, Path=SelectedIndex}" x:Key="AlternateConverter"/> Note: I removed the AlternateBrushes property as I only need static colors and add in HighlightItem property

问题 I'm developing a LOB app targeted to windows store and I'd like to know what are the options to create custom reports for it. The user may want to, besides printing, export to PDF or CSV.
