foreground

I'm looking for a simple way to change the foreground color of a TextBlock based on the color of what is behind it, so that it is more readable. Since an image is more explicit than words, here's what I want: I assume it could be done with a custom shader effect, but I have no idea how to create it... Anyway, perhaps there is a simpler solution. Any idea would be welcome! loxxy Assuming the above is a progressbar, here is a great solution: WPF progress bar with dynamic text & text color update Quick and dirty method: Add both the white and grey textblocks, ensuring the white textblock is "on

I'm looking to stop/dismiss a foreground notification for a service for a mediaplayer, much similar to Google's implementation for Google Music. For instance in Google Music, if you are playing music then the the notification cannot be swiped away. However if you pause the music it can. This is completely different to how it is implemented on Android 4.4, where the notification starts only when you leave the app and removes itself when you go back into the app. I can't see how to implement this either considering the requirements for a service to have a notification. Any help would be much

In my windows service I create one "parent" foreground thread that in turn spawns "child" threads using ThreadPool (which means they are background) to execute tasks. What is the best way to close foreground thread gracefully on windows service stop? Here is my current implementation (stripped out of task-specific logic): public partial class TaskScheduler : ServiceBase { private static AutoResetEvent _finishedTaskAutoResetEvent = new AutoResetEvent(false); //This flag is used to increase chances of the Spawning Thread to finish gracefully when service stops. private bool StopRequested { get;

I'm using Phonegap 2.3.0 and the new ForegroundCamera plugin from Google Code.. I followed the instructions carefully, and in my Eclipse setup I got the following errors when validating the project: Cannot cast from ForegroundCameraLauncher to Plugin ctx cannot be resolved or is not a field (x2) R cannot be resolved to a variable (x4) The method success(PluginResult, String) is undefined for the type ForegroundCameraLauncher Now, I solved the first three of the above errors by updating some deprecated code lines (I hope I got it solved - it doesn't show the errors anymore).. The first error

my app crashes when it comes back to foreground after some time playing with others applications and I can't find out how to fix it. My app has a splash screen activity where it loads some data from web services and put it in global static variables declared in a class extending Application, as explained in this SO question . Once all data are loaded, this activity launches a Home activity with some menu to navigate in the app. The global vars are used in most activities. At some point, while playing with other apps, it seems that my app is killed, because I can see this in the logcat: I

Short question: I'm trying to use the NotificationCompat.Builder class in order to create a notification that will be used for the service, but for some reason, i either don't see the notification, or can't cancel it when the service should be destroyed (or stopping from being in the foreground) . my code: @Override public int onStartCommand(final Intent intent, final int flags, final int startId) { final String action = intent == null ? null : intent.getAction(); Log.d("APP", "service action:" + action); if (ACTION_ENABLE_STICKING.equals(action)) { final NotificationCompat.Builder builder =

I require to set text color when text changes inside textbox and meets certain criterion. I can implement this from code behind with textbox_textchanged event and set brushes.color to desired color. But I am not being able to implement this with xaml wpf approach. I am new to wpf, I'm not sure how can I set text color depending upon certain criterion when text changes in textbox. For example: For a given textbox, when text changes, it needs to determine if input text is a number then change foreground color to green else red. Looking forward for the help. Thank you in advance. I am not sure
