Dictionary is a generic class Dictionary<TKey,TValue>, where as HashTable needs casting of the objects.

var Employees=new Dictionary<string,Employee>();
Employee emp=Employees[“JohnDoe”];

var Employees=new HashTable();
Employee emp=Employees[“JohnDoe”] as Employee;

Dictionary cannot be used with webservices as no webservices support generics.

Dictionary is implementation of the hashtable
Dictionary is TypeSafe, it can support multiple readers as long as the collection is not modified.

Here are my notes about view state:

• View state for a page or control  is the cumulative storage of values.
• Primary storage mechanism for HTML and webserver controls
• Attribute/Value pairs are stored like a dictionary
• Can read this class any time during the processing of the page except when the control is being rendered.
• you can add or remove from the dictionary like any other control
• View state is a way to store and retrieve controls from the statebag class
• State of control is maintained when it is rendered back to the page
• An instance of statebag class is created when you set the view state to true
• Control.ViewState is the property used to read and write to the viewstate.

Adioz tonight..

I wanted to refresh my memory about ASP.Net Page lifecycle management….trying to make some notes for myself

Pre Init – dynamically set Master Page or themes, Profile settings, create or recreate dynamic controls – like in dotnetnuke

Init – All the controls in the page have been initialized

InitComplete – After all the initialization

Preload – Perform any processing on a page or control before load
                  Page preload event and then the controls are fired
                 Viewstate and postback data gets initialized from the request object

PageLoad – After pageload each of the onload events for the controls gets fired

LoadComplete – all controls have been loaded by this time and validations done by this event, any thing depending on all the controls to be loaded

PreRender – Page object calls every databind controls, occurs for each control on the page, page Prerender event gets called after the prerender event of all the controls have been called

SaveStateComplete – View state for all the controls on the page is saved

Render method on every single control is called, Render method for the page

What is happening with Greece with respect to the financial crisis.

Somebody has Microsoft office, i will copy it….

Somebody has email, i will copy it…

Somebody has facebook, i will copy it…

Somebody has Twitter, i will copy it…

Somebody has SharePoint, i will copy it…

And i will call them – Googledocs,Gmail,Buzz and Google Wave….

I am not being hypocritical, i do like using Google because nobody can beat it in search as of now. But when Google tries to build products just to intimidate the big players it is really irritating.

Consider Gmail, it took 5 years to get it out from beta and given that Gmail is out of the beta phase,Gmail is still not free of outages. Google Doc’s still in Beta, i don’t know when a feature was last added to it.

Consider Google’s latest venture Google Buzz..it sucks to the core because it builds the network from the emails and chats that ever occurred from your email, which is a straight flop.

Well all i wanted to express was Google gets the idea off from a highly successful product like facebook or twitter and tries to emulate it. Not only does the starting point suck, it also tries to throw the product in the face of the huge user base it has from the search and mail.

Adios for the night..

I love the videos of lebron and kobe, NIKE does a great job of showing those puppets.
