settings

问题 I am using the built-in My.Settings functionality in VB.NET to save application settings. This is very convenient but I notice that each time I release a new version, the settings are lost. Why and how can I prevent it? 回答1: You need to manually update your application settings, I use this easy method: Create a boolean setting called MustUpgrade, User scope, default to True.

(jab, lol)... anyhow, can I default to debugging against IE? I know in VS2008 you just had to "Browse With..." on an .aspx page. But that option doesn't exist in VS2010 RC . What gives? 回答1: This is for VS2008, but should apply just as well to VS2010. You have several options. Go to the

问题 Anyone who knows why this code ain't lowering the backlight of my application? Context context = this; Settings.System.putInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS, 255); 回答1: Applications are no longer allowed to modify the global brightness.

问题 I want to watch a system setting and get notified when its value changes. The Cursor class has a setNotificationUri method which sounded nice, but it doesn't work and coding it also feels strange...
