Technical differences between Flash and Silverlight II

2009-06-14T23:52:00.000-07:00

File Size:

Flash

Flash uses a compressed format, and text and images are embedded in the movie, hence the file size of a Flash component is relatively small.

Silverlight:

Silverlight uses XAML for its description language, and it is non-compressed, so the size of a Silverlight component is usually larger.

Technical differences between Flash and Silverlight I

2009-06-14T23:46:00.000-07:00

Animation:
Flash:
Flash uses the frame-based animation model. In frame-by-frame animation, we create an object for each frame to produce an animation sequence.
For example, if you want to move something across the screen in 3 seconds, calculate how many frames 3 seconds will take, then calculate the matrices required for each frame along the way. Keep in mind that the player won’t actually maintain a frame rate unless you embed a blank audio track; otherwise, 3 seconds might turn out to be 2 or 6 or 5.

Silverlight:
Silverlight is based on the WPF animation model, which is time-based instead of frame-based, so you define the start and end conditions, and it figures out how to do it. No need to deal with matrices like with Flash. Also, no need to calculate the positions of objects in various frames.

MS Access vs Silverlight

2009-05-27T03:39:00.000-07:00

•MS Access is used as a backend.
• we need Web Service for connecting the database with Silverlight.
•Connecting MS Access with Silverlight is a simple than connecting it with SQL server.
•Silverlight + Access Database will give a rich application
eg:
public class Service1 : System.Web.Services.WebService
{ OleDbConnection con;
OleDbCommand cmd;
OleDbDataAdapter da;
DataSet ds;
[WebMethod]
public string Hello()
{
return "hai";
}
[WebMethod]
public string detail(string emp_id, string emp_name, string emp_dept)
{
string query;
con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\TenthPlanet\\emp_table.mdb");
con.Open();
try
{
query = "insert into table1 values(" + emp_id + ",'" + emp_name + "','" + emp_dept + "')";
cmd = new OleDbCommand(query, con);
cmd.ExecuteNonQuery();
da = new OleDbDataAdapter("select * from Table1", con);
ds = new DataSet();
da.Fill(ds);
return "inserted succ";
}
catch (Exception e)
{
return e.Message ;
}

What is Storyboard?

2009-05-27T03:06:00.001-07:00

*Storyboard is a Silverlight class with controls animations with a timeline, and provides object and property targeting information for its child animations

Is Silverlight plug-in free?

2009-05-27T02:54:00.001-07:00

*Yes, Microsoft will make the Silverlight browser plug-in freely available for all supported platforms.

Does silverlight web application work with all browsers ?

2009-05-27T02:53:00.000-07:00

*Yes, A web application developed by silverlight technology can work with any browser

App.xaml

2009-05-27T02:38:00.000-07:00

•App.xaml and App.xaml.cs – The App.xaml is required to configure your Silverlight application. You can also declare resources that will be available in all pages of your application.
•App.xaml is a file used by Silverlight applications to declare shared resources like brushes, various style objects etc.
• The code behind file of app.xaml is used to handle global application level events like Application_Startup, Application_Exit and Application_UnhandledException. (Similar to Global.asax file for ASP.NET applications)

Page.xaml

2009-05-27T02:30:00.000-07:00

•Page.xaml and Page.xaml.cs – Contains the UI and the C# code to run the Silverlight application.
•When you create a Silverlight project using Visual Studio 2008, it creates a default xaml file called "Page.xaml".
•This is just a dummy start page created by Visual Studio and it does not contain any visible UI elements
The default content of the page.xaml file
•(UserControl x:Class="MySilverlightApp.Page"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300")(Grid x:Name="LayoutRoot" Background="White")(/Grid)(/UserControl)
•All UI elements in a .xaml control must be placed within a layout panel.

•The most important file to look at right now would be the Page.xaml file because this is the file that will be used to define the user interface of the application.
•Page.xaml is like the core of a Silverlight-Blend project/solution.

The Silverlight core presentation framework

2009-05-27T02:16:00.000-07:00

The Silverlight core presentation framework is a subset of the Windows Presentation Foundation
language. The core presentation framework provides the libraries and utilities necessary to parse
the Silverlight XAML files, present the UI to the browser, and handle interaction from the user.

The following is a list of components that are included with the core presentation framework listed

*XAML parser: Parses the XAML files into objects.
* UI renderer: Handles rendering of XAML objects, such as vector/bitmap graphics, animation,
and text, into UI elements that are displayed in the applications.
*Layout: Utilizes canvas, grid, and other controls to dynamically position and size UI
elements.
* Controls: Implements extensible controls, such as buttons, sliders, calendars, and text
boxes, which provide customizable functionality to applications.
*Media pipeline: Provides streaming of audio and video files as well as playback and
other management.
*Data binding: Enables data objects to be directly linked to UI elements in a one-way or
two-way relationship. Changes to values can then be reflected automatically using the link.
*Input: Handles the input from user input devices such as a mouse, keyboard, and other
input requests.
*DRM: Implements digital rights management to protect media files in Web applications.

The Silverlight plug-in

2009-05-27T02:12:00.000-07:00

*The Silverlight plug-in is a very lightweight component that is necessary for users to access
Silverlight applications. The plug-in download and install take only a few moments and do not
take up much hard drive space.

*When a Web page containing a Silverlight application is displayed, the user should
be given a link to download the plug-in from Microsoft if the plug-in is not already
installed.

*The Silverlight plug-in is responsible for accessing the Silverlight object in the Web page, downloading
and accessing the XAP package, setting up the program environment, and beginning execution
of the application.

Silverlight Full Screen Support

2009-05-27T01:52:00.000-07:00

Silverlight applications can display in two different modes.
*In Embedded Mode, the Silverlight application displays within the content area of a web page. *Full-Screen Mode, the Silverlight application occupies the entire screen and displays on top of all other running applications.
To switch modes, we simply set the Content.
IsFullScreen property in the System.Windows.Interop namespace. For example, the following line sets the Silverlight application to full screen mode:
Content.IsFullScreen = true;

Silverlight Font Support

2009-05-27T01:48:00.000-07:00

*Silverlight supports a collection of common fonts out of the box. These fonts are Arial, Arial Black, Comic Sans, Courier New, Georgia, Lucida Grande, Times New Roman, Trebuchet, and Verdana, Silverlight supports a collection of common fonts out of the box. These fonts are Arial, Arial Black, Comic Sans, Courier New, Georgia, Lucida Grande, Times New Roman, Trebuchet, and Verdana,
So what if an application requires another font? Silverlight also supports custom fonts, and the steps to use a custom font are as follows:
*Add the font file (.ttf) into your Silverlight Project by selecting Project/Add Existing Item.
*Set the Build Action of the .ttf file to Resource
*Note the Font Name (the embedded name in the font file). If you are not sure what this is, double-click the .ttf file in Windows Explorer and the Font Name will be displayed at the top of the Font Viewer.
*Inside your XAML element (TextBlock, TextBox, etc), set the FontFamily in the format "FontFile#FontName" - For example, to set to a Font named Times Square inside a font file named TIMES_SQ.TTF, you would use:
{TextBlock FontFamily="TIMES_SQ.TTF#Times Square" FontSize="32" TextWrapping="Wrap" Text="This TextBlock is using a Custom, Embedded Font." /}

Silverlight Drawing

2009-05-27T00:10:00.000-07:00

Definition
*Silverlight can be used to provide a richer experience in drawing and image filtering
*In Silverlight, a Shape is a type of UIElement that enables you to draw a shape to the screen. Because they are user interface (UI) elements, Shape objects can be used inside a variety of container objects such as Grid and Canvas.
*In Silverlight, a Shape is a type of UIElement that enables you to draw a shape to the screen. Because they are user interface (UI) elements, Shape objects can be used inside a variety of container objects such as Grid and Canvas.
Types of drawing
*Rectangle
*Ellipse
*Path

It’s easy to draw and manage shapes in Expression Blend, but when it comes to generate shapes automatically we realize that it’s much harder. Lucky for us all properties can be set in code and all shapes can be drawn.
Advantages
*With the advantage of rendering speed, Flash and Silverlight can provide a richer experience in drawing and image filtering. Moreover, by using the Timer Event, real time replay of drawing bring us into another generation of art.

API

2009-04-17T02:23:00.000-07:00

(Application Programming Interface) A language and message format used by an application program to communicate with the operating system or some other control program such as a database management system (DBMS) or communications protocol. APIs are implemented by writing function calls in the program, which provide the linkage to the required subroutine for execution. Thus, an API implies that some program module is available in the computer to perform the operation or that it must be linked into the existing program to perform the tasks.

Create dll to display given text by clicking a button:
Step1:open Visual studio Dot.net and select the class library in silverlight and give a name for ur project. i gived it as exdll.

Step2:right click exdll from solution explorer and create a new folder named it as “themes”.under this folder create new .xaml file named it as “generic” don’t change this name.

*create one more new folder under “exdll” and named it as “cl” under this folder add a new class file named “txt” Step3:create design in “generic.xaml” file

Eg:

Step4: declaration and event codings are done in “txt.cs” file
Eg: namespace exdll.cl
{
public class txt : Control
{

public txt()
{
DefaultStyleKey = typeof(txt);

}

private TextBox text1;
private Button b1;

public override void OnApplyTemplate()
{
base.OnApplyTemplate();
text1 = base.GetTemplateChild("t1") as TextBox;
b1 = base.GetTemplateChild("btn") as Button;
if (b1 == null)
return;
if (text1 == null)
return;

b1.Click += new RoutedEventHandler(b1_click); //clickevent
}
void b1_click(object sender, RoutedEventArgs e)
{
string s = "hai";
text1.Text = s;

}
}
}
Step5:now build the project.
Step6:open new silverlight application and ur dll file.by right clicking tool box select “choositems” in the silverlight component select ur appropriate dll.then run ur project.
