Creating Timestamp

Image
By
In Objective C and iOS , Some times you need to create a time stamp(Unix Time Stamp Style) you use like this :

NSString * timeStampValue = [NSString stringWithFormat:@"%d", (long)[[NSDate date] timeIntervalSince1970]];
NSLog(@"Time Stamp Value == %@", timeStampValue);
/*
Explain:
This translates to current server time of 04/13/2012 @ 8:41am in EST.
TIME STAMP: 1334320615
DATE (M/D/Y @ h:m:s): 04 / 13 / 12 @ 7:36:55am EST

*/

Output : 1334320615

WPF-MVVM: RelayCommand Implementation

By
In WPF if we are implementing MVVM pattern then we need to play with Command rather than Events. You can use ICommand interface to create each command class. Implementation of ICommand in a class gives you CanExecute(), Execute() methods which take part in the action performed by Command.   Rather than making Command Class for each Command we can implement a generic Relay Command to get Command. Below is a RelayCommand class that we will implement.   ///   <summary>      ///  To register commands in MMVM pattern      ///   </summary>      class   RelayCommands  :  ICommand     {          readonly   Action < object > _execute;          readonly   Predicate < object > _canExecute;  ...

.Net List with Changed event

By
Sometimes we need a List which can notify user when an item is added. Here is the way that you can implement a generic ArrayList which notifies user at the time of an element is added.   using  System; using  System.Collections; namespace  ArchiveData.Logging {    // A delegate type for hooking up change notifications.    public   delegate   void   ChangedEventHandler ( object  sender,  EventArgs  e);    public   class   ListWithChangedEvent  :  ArrayList   {      // An event that clients can use to be notified whenever the      // elements of the list change.      public   event   ChangedEventHandler  Changed;      public   object  NewlyAddedItem {...

What is DispatcherTimer in wpf?

By
DispatcherTimer When you want to set a timer working with GUI, you always come across threading problem. The problem is that if you want to send some changes to UI that is constantly/continuously changing then that will make your UI unresponsive or in other words it will hang your UI.   To overcome from this situation, WPF gives us DispatcherTimer threading functionality that will take care of such continuously changing processing on UI thread and that will not hang your UI. We can accomplish same scenario in Win Form , through System.Windows.Forms.Timer and in WPF it is System.Windows.Threading.DispatcherTimer .   Difference between DispatcherTimer and Regular timer (System.Timers.Timer) DispatcherTimer is the regular timer. It fires its Tick event on the UI thread, you can do anything you want with the UI. System.Timers.Timer is an asynchronous timer, its Elapsed event runs on a thread pool thread. You have to be very careful in your event handler...
