event-handling

I'm using WinForms. I've created an event handler for the KeyDown event of the main form, thereby invoking a button's Click event handler. The Click event handler called is dependent upon the specific key pressed. If a user clicks the button rather than using the key, and then subsequently tries to use the key thereafter, the key (down arrow for example) acts as a tab-cycle, changing focus between each button control on the form (rather than executing the Keydown handler). Any ideas ? The problem is, the button has the focus when it is clicked, so subsequent key presses are not caught by the

I need to reset notification when user removes my app from background.So I need to have an event of remove app from background. Please help me out. Suggestion appreciated. Thanks. Kind Regards. Official android documentation Activity.onDestroy() The final call you receive before your activity is destroyed. This can happen either because the activity is finishing (someone called finish() on it, or because the system is temporarily destroying this instance of the activity to save space. You can distinguish between these two scenarios with the isFinishing() method. http://developer.android.com

I have a video file playing in a media element. I need to keep it playing, thus I tried: me.play(); me.MediaEnded += new RoutedEventHandler(me_MediaEnded); With this event method: //loop to keep video playing continuously void me_MediaEnded(object sender, EventArgs e) { //play video again me.Play(); } However the above does not replay the video file. Why? What did I do wrong? According to a post on MSDN : Play() starts from the current position therefore you have to first go to the starting place and then play it again. So you have to reset the position before replaying: me.Position = TimeSpan

I've got an ASP.NET application that I'm accessing through Google Chrome. On a particular page I've got an asp:TextBox with a OnTextChanged event that recalculates a few other fields on the page. I've also got an asp:LinkButton with an OnClick event that saves the changes to the database. I was facing a problem where the user left the TextBox by clicking on the save button. The button was firing before the TextChanged event so the changes were not being captured in the save. I fixed this by duplicating the TextChanged logic at the beginning of the save method. Did some testing before I

I'm writing an Android app that communicates with a PC via bluetooth. During normal operation, it sends out a rapid succession of short 8 byte packets from the Phone to the PC, typically at >100Hz. On each device, a separate thread is running that execute writes and reads. The code looks like this: /** * The Class ProcessConnectionThread. */ public class ConnectedThread extends Thread { /** The m connection. */ private StreamConnection mmConnection; InputStream mmInputStream; OutputStream mmOutputStream; private boolean mmCanceled = false; /** * Instantiates a new process connection thread. *

Instructions: make this code work without modifying snippet it in any way. Use only plain old JavaScript and no third-party libraries. Write new code that enables the code below to work properly. Hint: Feel free to extend native objects... even though it's typically a bad practice. // Start with an object, any object var myObject = {}; // Register an event on your object using // an `on` method myObject.on('myEvent', function(data) { // Log the data passed to the callback console.log(data); }); // Trigger the event using a `trigger` method. // Include some data when you trigger the event.
