Beginning E-Commerce with Visual Basic, ASP, SQL Server 7.0 and MTS

Beginning E-Commerce offers an excellent demonstration of full-featured e-commerce Web-site construction with the Microsoft suite of development tools. If VB is your language of choice and ASP is your Web scripting selection, this tutorial is a must.

Beginning E-Commerce

For download this book from Uploaded.net

This book has very little general coverage of e-commerce. The entire text is devoted to the step-by-step construction of "Jo's Coffee," a fictitious Web storefront that winds up at the end of the book with a sophisticated order-processing pipeline, online discussion groups, XML integration with outside systems, and much more. In the introduction, the book sets a lofty goal: "... to take you gently from knowing nothing about e-commerce, to a point where you'll be able to put up a Web site that will make money for your business." This text meets this goal for readers who are familiar with the development tools mentioned in the title.

The book does a great job of providing complete commentary for each stage of the development process. It walks the reader through defining an application object model, implementing it with VB COM components, interfacing with a SQL Server database, and adding a number of sophisticated features. One of the most interesting techniques illustrated in this title is a VB COM component-based order-processing pipeline similar to the type found in Microsoft's top-of-the-line Site Server product. Using the example in this book, developers could easily construct custom pipelines for every commerce site they build.

HTML5 Canvas Example

yalltech.net@gmail.com (beshoy sorial) — Thu, 6 Jun 2013 04:53:00 -0700

To show how to put the Canvas element to work, we’re going to create an example named canvas.html, which you can see running in Firefox in Figure

Canvas example

To get started with the canvas.html example, follow these steps:

Create canvas.html using a text editor such as Windows WordPad .
Enter the following code to create the <canvas> element and to set up the JavaScript. Note that we’re going to put our JavaScript in a function named loader, which is run only after the Canvas element is fully loaded by the browser:

<!DOCTYPE html>
<html>
<head>

<title>
Canvas Example
</title>
<script type=”text/javascript”>
function loader()
{
}

</script>
</head>

<body onload=”loader()”>
<h1>Canvas Example</h1>
<canvas id=”canvas” width=”600”
height=”500”>
</canvas>
</body>
</html>
Add the JavaScript to create an object corresponding to the Canvas element as shown. We’ll use this object to access the Canvas element in JavaScript.

<!DOCTYPE html>
<html>
<head>
<title>
Canvas Example
</title>
<script type=”text/javascript”>
function loader()
{
var canvas = document.getElementById
(‘canvas’);
var canvas1 = canvas.getContext(‘2d’); .
</script>
</head>
<body onload=”loader()”>
<h1>Canvas Example</h1>

<canvas id=”canvas” width=”600”

height=”500”>

</canvas>

</body>

</html>
Save canvas.html. Make sure you save this code in text format.The default format for WordPad, for example, is RTF, rich-textformat, which won’t work with browsers.

For Download this book from Uploaded.net

Calvert and Kulkarni begin by clearly explaining how LINQ resolves the long-time “impedance mismatch” between object-oriented code and relational databases. Next, they show how LINQ integrates querying into C# as a “first-class citizen.” Using realistic code examples, they show how LINQ provides a strongly typed, IntelliSense-aware technology for working with data from any source, including SQL databases, XML files, and generic data structures.

Calvert and Kulkarni carefully explain LINQ’s transformative, composable, and declarative capabilities. By fully illuminating these three concepts, the authors allow developers to discover LINQ’s full power. In addition to covering core concepts and hands-on LINQ development in C# with LINQ to Objects, LINQ to XML, LINQ to SQL, and LINQ to Entities, they also present advanced topics and new LINQ implementations developed by the LINQ community.

The HTML5 Canvas element is a popular one, used to display graphics. The element itself is created very simply in HTML5, like this:
The Canvas element can draw lines, arcs, complex shapes, images, text, and more.

Technically speaking, the Canvas element is very simple in HTML5. Here’s the specification:

Elements:<canvas>
Start tag required: Yes
End tag required: Yes
Required attributes: Height, width
Supported browsers: Chrome, Firefox, Opera, Safari

The real story takes place in JavaScript with this element, and it will let us draw in the Canvas element example that we’ll develop in this post

Canvas Example

Casting Shadows

The Canvas element even lets you add shadows to your graphics with these attributes:

attribute float shadowBlur; // (default 0)
attribute DOMString shadowColor; // (default transparent black)
attribute float shadowOffsetX; // (default 0)
attribute float shadowOffsetY; // (default 0)

Drawing Rectangles

Here are the functions you use for rectangles:

clearRect(float x, float y, float w, float h);
fillRect(float x, float y, float w, float h);
strokeRect(float x, float y, float w, float h);

Drawing Complex Shapes

With the Canvas element, you can draw arcs, Bezier curves, and more using these functions:

arc(float x, float y, float radius, float startAngle, float endAngle, boolean anticlockwise);
arcTo(float x1, float y1, float x2, float y2, float radius);
beginPath();
bezierCurveTo(float cp1x, float cp1y, float cp2x, float cp2y, float x, float y);
clip();
closePath();
fill();
lineTo(float x, float y);
moveTo(float x, float y);
quadraticCurveTo(float cpx, float cpy, float x, float y);
rect(float x, float y, float w, float h);
stroke();
boolean isPointInPath(float x, float y);

Drawing Some Text

You can also write text in a Canvas using these attributes and functions:

attribute DOMString font; // (default 10px sans-serif)
attribute DOMString textAlign; // “start”, “end”, “left”, “right”, “center” (default: “start”)
attribute DOMString textBaseline; // “top”, “hanging”, “middle”, “alphabetic”, “ideographic”, “bottom” (default: “alphabetic”)
fillText(DOMString text, float x, float y, optional float maxWidth);
TextMetrics measureText(DOMString text);
strokeText(DOMString text, float x, float y, optional float maxWidth);

Drawing Images

You can draw images with these functions:

drawImage(HTMLImageElement image, float dx, float dy, optional float dw, float dh);
drawImage(HTMLImageElement image, float sx, float sy, float sw, float sh, float dx, float dy, float dw, float dh);
drawImage(HTMLCanvasElement image, float dx, float dy, optional float dw, float dh);
drawImage(HTMLCanvasElement image, float sx, float sy, float sw, float sh, float dx, float dy, float dw, float dh);
drawImage(HTMLVideoElement image, float dx, float dy, optional float dw, float dh);
drawImage(HTMLVideoElement image, float sx, float sy, float sw, float sh, float dx, float dy, float dw, float dh);

Using Transformations

You can rotate, resize (scale), or move (translate) graphics with these functions:

rotate(float angle);
scale(float x, float y);
translate(float x, float y);

That’s the overview of the Canvas

.NET Interview Question: Garbage Collection

yalltech.net@gmail.com (beshoy sorial) — Sun, 26 May 2013 10:17:00 -0700

Q1. What is garbage collection?

Garbage collection is a heap-management strategy where a run-time component takes responsibility for managing the lifetime of the memory used by objects. This concept is not new to .NET - Java and many other languages/runtimes have used garbage collection for some time.

Q2. Is it true that objects don't always get destroyed immediately when the last reference goes away?

Yes. The garbage collector offers no guarantees about the time when an object will be destroyed and its memory reclaimed.

There was an interesting thread on the DOTNET list, started by Chris Sells, about the implications of non-deterministic destruction of objects in C#. In October 2000, Microsoft's Brian Harry posted a lengthy analysis of the problem. Chris Sells' response to Brian's posting is here.

Q3. Why doesn't the .NET runtime offer deterministic destruction?

Because of the garbage collection algorithm. The .NET garbage collector works by periodically running through a list of all the objects that are currently being referenced by an application. All the objects that it doesn't find during this search are ready to be destroyed and the memory reclaimed. The implication of this algorithm is that the runtime doesn't get notified immediately when the final reference on an object goes away - it only finds out during the next 'sweep' of the heap.

Futhermore, this type of algorithm works best by performing the garbage collection sweep as rarely as possible. Normally heap exhaustion is the trigger for a collection sweep.

Q4. Is the lack of deterministic destruction in .NET a problem?

It's certainly an issue that affects component design. If you have objects that maintain expensive or scarce resources (e.g. database locks), you need to provide some way to tell the object to release the resource when it is done. Microsoft recommend that you provide a method called Dispose() for this purpose. However, this causes problems for distributed objects - in a distributed system who calls the Dispose() method? Some form of reference counting or ownership-management mechanism is needed to handle distributed objects - unfortunately the runtime offers no help with this.

Q5. Should I implement Finalize on my class? Should I implement IDisposable?

This issue is a little more complex than it first appears. There are really two categories of class that require deterministic destruction - the first category manipulate unmanaged types directly, whereas the second category manipulate managed types that require deterministic destruction. An example of the first category is a class with an IntPtr member representing an OS file handle. An example of the second category is a class with a System.IO.FileStream member.

For the first category, it makes sense to implement IDisposable and override Finalize. This allows the object user to 'do the right thing' by calling Dispose, but also provides a fallback of freeing the unmanaged resource in the Finalizer, should the calling code fail in its duty. However this logic does not apply to the second category of class, with only managed resources. In this case implementing Finalize is pointless, as managed member objects cannot be accessed in the Finalizer. This is because there is no guarantee about the ordering of Finalizer execution. So only the Dispose method should be implemented. (If you think about it, it doesn't really make sense to call Dispose on member objects from a Finalizer anyway, as the member object's Finalizer will do the required cleanup.) For classes that need to implement IDisposable and override Finalize, see Microsoft's documented pattern.

Note that some developers argue that implementing a Finalizer is always a bad idea, as it hides a bug in your code (i.e. the lack of a Dispose call). A less radical approach is to implement Finalize but include a Debug.Assert at the start, thus signalling the problem in developer builds but allowing the cleanup to occur in release builds.

Q6. Do I have any control over the garbage collection algorithm?

A little. For example the System.GC class exposes a Collect method, which forces the garbage collector to collect all unreferenced objects immediately.

Also there is a gcConcurrent setting that can be specified via the application configuration file. This specifies whether or not the garbage collector performs some of its collection activities on a separate thread. The setting only applies on multi-processor machines, and defaults to true.

Q7. How can I find out what the garbage collector is doing?

Lots of interesting statistics are exported from the .NET runtime via the '.NET CLR xxx' performance counters. Use Performance Monitor to view them.

Q8. What is the lapsed listener problem?

The lapsed listener problem is one of the primary causes of leaks in .NET applications. It occurs when a subscriber (or 'listener') signs up for a publisher's event, but fails to unsubscribe. The failure to unsubscribe means that the publisher maintains a reference to the subscriber as long as the publisher is alive. For some publishers, this may be the duration of the application.

This situation causes two problems. The obvious problem is the leakage of the subscriber object. The other problem is the performance degredation due to the publisher sending redundant notifications to 'zombie' subscribers.

There are at least a couple of solutions to the problem. The simplest is to make sure the subscriber is unsubscribed from the publisher, typically by adding an Unsubscribe() method to the subscriber. Another solution, documented here by Shawn Van Ness, is to change the publisher to use weak references in its subscriber list.

Q9. When do I need to use GC.KeepAlive?

It's very unintuitive, but the runtime can decide that an object is garbage much sooner than you expect. More specifically, an object can become garbage while a method is executing on the object, which is contrary to most developers' expectations. Chris Brumme explains the issue on his blog. I've taken Chris's code and expanded it into a full app that you can play with if you want to prove to yourself that this is a real problem:

using System;

using System.Runtime.InteropServices;

class Win32

{

[DllImport("kernel32.dll")]

public static extern IntPtr CreateEvent( IntPtr lpEventAttributes,

bool bManualReset,bool bInitialState, string lpName);

[DllImport("kernel32.dll", SetLastError=true)]

public static extern bool CloseHandle(IntPtr hObject);

[DllImport("kernel32.dll")]

public static extern bool SetEvent(IntPtr hEvent);

}

class EventUser

{

public EventUser()

{

hEvent = Win32.CreateEvent( IntPtr.Zero, false, false, null );

}

~EventUser()

{

Win32.CloseHandle( hEvent );

Console.WriteLine("EventUser finalized");

}

public void UseEvent()

{

UseEventInStatic( this.hEvent );

}

static void UseEventInStatic( IntPtr hEvent )

Satish Marwat Dot Net Web Resources satishcm@gmail.com 12 Page

{

//GC.Collect();

bool bSuccess = Win32.SetEvent( hEvent );

Console.WriteLine( "SetEvent " + (bSuccess ? "succeeded" : "FAILED!") );

}

IntPtr hEvent;

}

class App

{

static void Main(string[] args)

{

EventUser eventUser = new EventUser();

eventUser.UseEvent();

}

If you run this code, it'll probably work fine, and you'll get the following output:

SetEvent succeeded

EventDemo finalized

However, if you uncomment the GC.Collect() call in the UseEventInStatic() method, you'll get this output:

EventDemo finalized

SetEvent FAILED!

(Note that you need to use a release build to reproduce this problem.)

So what's happening here? Well, at the point where UseEvent() calls UseEventInStatic(), a copy is taken of the hEvent field, and there are no further references to the EventUser object anywhere in the code. So as far as the runtime is concerned, the EventUser object is garbage and can be collected. Normally of course the collection won't happen immediately, so you'll get away with it, but sooner or later a collection will occur at the wrong time, and your app will fail.

A solution to this problem is to add a call to GC.KeepAlive(this) to the end of the UseEvent method, as Chris explains.

.NET Interview Question: Application Domains

yalltech.net@gmail.com (beshoy sorial) — Sun, 26 May 2013 03:45:00 -0700

Q1. What is an application domain?

An AppDomain can be thought of as a lightweight process. Multiple AppDomains can exist inside a Win32 process. The primary purpose of the AppDomain is to isolate applications from each other, and so it is particularly useful in hosting scenarios such as ASP.NET. An AppDomain can be destroyed by the host without affecting other AppDomains in the process.

Win32 processes provide isolation by having distinct memory address spaces. This is effective, but expensive. The .NET runtime enforces AppDomain isolation by keeping control over the use of memory - all memory in the AppDomain is managed by the .NET runtime, so the runtime can ensure that AppDomains do not access each other's memory.

One non-obvious use of AppDomains is for unloading types. Currently the only way to unload a .NET type is to destroy the AppDomain it is loaded into. This is particularly useful if you create and destroy types on-the-fly via reflection.

Q2. How does an AppDomain get created?

AppDomains are usually created by hosts. Examples of hosts are the Windows Shell, ASP.NET and IE. When you run a .NET application from the command-line, the host is the Shell. The Shell creates a new AppDomain for every application.

AppDomains can also be explicitly created by .NET applications. Here is a C# sample which creates an AppDomain, creates an instance of an object inside it, and then executes one of the object's methods:

using System;

using System.Runtime.Remoting;

using System.Reflection;

public class CAppDomainInfo : MarshalByRefObject

{

public string GetName() { return AppDomain.CurrentDomain.FriendlyName; }

}

public class App

{

public static int Main()

{

AppDomain ad = AppDomain.CreateDomain( "Andy's new domain" );

CAppDomainInfo adInfo = (CAppDomainInfo)ad.CreateInstanceAndUnwrap(

Assembly.GetCallingAssembly().GetName().Name, "CAppDomainInfo" );

Console.WriteLine( "Created AppDomain name = " + adInfo.GetName() );

return 0;

}

Q3. Can I write my own .NET host?

Yes. For an example of how to do this, take a look at the source for the dm.net moniker developed by Jason Whittington and Don Box. There is also a code sample in the .NET SDK called CorHost.
