overriding

I'm trying to come to grips with the onSaveInstanceState method in class View (not the one in class Activity ). That method does return a Parcelable . I derived my own View from ViewGroup and overrode that method to save my own state. But when the state was to be saved I got an exception: java.lang.IllegalStateException: Derived class did not call super.onSaveInstanceState() That is true enough, but simply calling that method doesn't seem enough to me. So how should I do this? If the method would get passed a Parcel to write to, I could simply pass that same parcel to the super class, so

I have an application, that uses the MultiSelectionModel, and it works great, but I need the site I'm developing to work on mobile devices, and so I can't use the keyboard to assist in selecting the elements (since it doesn't exist). EX: On the desktop I just hold ctrl and click on all the element that I want to select. So on the mobile device, I would like to modify the default behavior of the MultiSelectionModel so that when you click on a CellList item, it toggles the selection state of that item. I have looked through the source for it and cannot see anyway to implement the behavior that I

I want to know if user is scrolling up or down. I have began to override the OnGestureListener.onScroll() method and set my GestureDetector for the ListView . public class ContactList extends ListView { GestureDetector gestureDetector; public ContactList(Context context) { super(context); initView(); } public ContactList(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); initView(); } public ContactList(Context context, AttributeSet attrs) { super(context, attrs); initView(); } private void initView() { gestureDetector = new GestureDetector(new

I'm using the System.Diagnostics.Process class to execute a command line program. I am using the OutputDataReceived method to redirect the output to my own method. pr.OutputDataReceived += new DataReceivedEventHandler(OnDataReceived); pr.ErrorDataReceived += new DataReceivedEventHandler(OnDataReceived); However, I have multiple Threads running multiple instances of this cmd program. What I want to do is to be able to identify which process instance the output data came from - ideally, a string containing a name. (Each process has it's own progress bar on a GUI. I create another event to pass

I'm a beginner to c# programming and recently started working on a bachelors degree. What I'm trying to say is, I'm new. I have marked the place where I have the problem. The problem is that I don't understand why I need to put override in the code at all. There is 2 var of the type object (first and rest). public Pair() { first = rest = null; } public Pair(Object o) { first = o; rest = null; } public Object First() { return(first); } public Object Rest() { return(rest); } public Pair Connect(Object o) { rest = o; return(this); } //Here is the "override string ToString" I don't understand. Why

I have this abstract class: public abstract class Task { public string ID {get; set;} public string Name {get; set;} public abstract class Options{}; public abstract void Execute(); } I have other classes extending this class: public class Copy : Task { public override void Execute() { Console.Write ("running"); } } I'd like each derived class to implement their own Options class so they can have their own parameters. So Search class have to implement it's own Options class with the properties it needs, such as " includesubfolders ", " casesensitive ", etc.. Meanwhile Move task can implement

I'm trying to override in the local folder a module which is in the local folder also, but I don't know if it's possible. This is what I've done. I've created /local/Mycompany/Modulename/Model/Model.php which i'd like to override the /local/Othercompany/Modulename/Model/Model.php my model.php is: class Mycompany_Modulename_Model_Model extends Othercompany_Modulename_Model_Model { ... } and my config.xml <global> <models> <othercompanymodulename> <rewrite> <model>Mycompany_Modulename_Model_Model</model> </rewrite> </othercompanymodulename> </models> The class is been instantiated whith Mage:

There is a cherry-pick command in the git which allows me to copy some commit on top of the current. However, it does some conflict resolution, that I do not care about. What is alternative to cherry-pick which just copies picked commit over on top of current commit? I can do it manually: select desired commit, copy its files, save them into non-managed folder, select current commit which will be the base for new one, copy the archived files into the git working folder. Separately, I have to copy the commit message. This is huge hassle that I do currently to avoid the change conflicts. Which
