When an object instance is destroyed, ASP calls a special parameter-less sub named Class_Terminate. For example, when the variable falls out of scope. Since you cannot specify parameters for this sub, you also cannot overload it.

When an object instance is created from a class, ASP calls a special sub called Class_Initialize.

How do you find last Monday? I want to return a date for last Monday or today if today is Monday.

While Weekday(ADate) <> vbMonday
     ADate = DateAdd("d", -1, ADate)
WEnd

You could wrap this up in a function as follows: 

Function SU_GetLastDOW(ADate, AWeekDayConst)
    While Weekday(ADate) <> AWeekDayConst
        ADate = DateAdd("d", -1, ADate)
    WEnd
    
    SU_GetLastDOW = ADate
End Function

In C#, you use the class keyword to specify a class and you signify its parent with a colon and the name of the parent class. When you instantiate an object from a class, you use the new keyword.

Use a destructor to free unmanaged resources. A destructor is a method with the same name as the class but preceded with a tilde (as in ~ClassName). The destructor implicity creates an Object.Finalize method (you cannot directly call nor override the Object.Finalize method).

In C# you cannot explicitly destroy an object. Instead, the .Net Frameworks garbage collector (GC) takes care of destroying all objects. The GC destroys the objects only when necessary. Some situations of necessity are when memory is exhausted or you explicitly call the System.GC.Collect method. In general, you never need to call  System.GC.Collect.

In C# you can set the visibility of a member field to any visibility: private, protected, public, internal or protected internal. You can intialize a member field with a default when declared. If you set the member field value in your constructor, it will override the default value. Finally, you can use the static modifier (no instance required) and readonly modifier (similar to a constant).

Define class:

public class Cyborg : System.Object
{
  public virtual void IntroduceYourself()
  {
    MessageBox.Show("Hi, I do not have a name yet.");  
  }
}

Create object from class:

Cyborg T1 = new Cyborg();
T1.IntroduceYourself();

How do you resolve the UserID of a user when using ASP.NET 2.0's built in Membership utility?

//GetUser() returns current user information
MembershipUser myUser = Membership.GetUser();

  

//Returns the UserID and converts to a string
string UserID = myUser.ProviderUserKey.ToString();

A member function with the same name as the class prefixed with a ~ (tilde). C++ destructors are automatically called when an object goes out of scope, or when you delete a dynamically allocated object. Every class can have only one destructor.

class Cyborg {
public:
  // Constructor for class Cyborg
  Cyborg();

  
  // Destructor for class Cyborg
  ~Cyborg();
};

Use two forward slashes to represent a single line comment:

// This is a C++ style single line comment.

You can also use multiple line comments:

/*
This is a mutliple line comment. This
syntax is borrowed from C.
*/

Also known as a Class Field.

A class variable defined with a specific class visibility, usually private visibility. A member property is different than a member field. A member property uses a member field to store values through accessor methods (getters and setters). For example, it is common to use a private member field to store the current value of a property. The current values of all the class member fields is the current state of the object.

A partial class, or partial type, is a class that can be split into two or more source code files and/or two or more locations within the same source file. Each partial class is known as a class part or just a part. Logically, partial classes do not make any difference to the compiler. The compiler puts the class together at compile time and treats the final class or type as a single entity exactly the same as if all the source code was in a single location.

According to Microsoft, "PowerCommands is a set of useful extensions for the Visual Studio 2008 adding additional functionality to various areas of the IDE. The source code is included and requires the VS SDK for VS 2008 to allow modification of functionality or as a reference to create additional custom PowerCommand extensions. "

If you've previously worked with Delphi and GExperts, you know how helpful some extensions to your IDE can be.

This free download, from Microsoft, adds some really useful functionality to the VS2008 IDE.  Check it out.

Specify Delphi member modifiers as follows:

reintroduce; overload; [binding modifier]; [calling convention]; abstract; [warning]

The binding modifiers are virtual, dynamic, or override. The calling conventions are register, pascal, cdecl, stdcall, or safecall. The warnings are platform, deprecated, or library. Additional directives include reintroduce, abstract, class, static, overload, and message.

Up until D2005, private and protected were not implemented strictly. Starting with D2005, a traditional strict versions of OOP are supported using the strict keyword. OO purist will want you to use strict private over private and strict protected over protected. I suggest you follow that advice until you both fully understand the differences and have a specific need. Delphi offers a special published specifier which is the same as public members but runtime type information (RTTI) is generated.

TCyborg = class(System.Object)
private
  //Don't use accept when you really want private friendly members.
strict private
  //Use as your default private members.

  FName: String;
protected
  //Don't use accept when you really want protected friendly members.

strict protected
  //Use as your default protected members.

public

  

published

  //RTTI Info

end;

Use the Screen variable which is a TScreen. The Screen variable is a TScreen component that represents the screen of the system on which the application runs. By default, applications create a screen component based on information from Windows about the current screen device and assign it to Screen.

For example, put the following code in a button click:

MessageDlg( 'screen width = ' + IntToStr( Screen.Width ) + ',
  screen height = ' + IntToStr( Screen.Height ), 

    mtInformation, [mbOk], 0 );

Java has a garbage collection algorythm that runs as a background task so it has no destructors. You can use the finalize() method to close additonal resources such as file handles.

protected void finalize() throws Throwable {
try {
	close(); // close open files
} finally {
	super.finalize();
}
}

JavaScript is case sensitive. Change the case, and it no longer works! Notice the "W" in "Write" is capitalized.

<script language=JavaScript> 
<!--
document.Write("Hello"); //Does not work! 
//--> 
</script>

Variable names are case sensitive.

This does work:

<script language=JavaScript> 
<!--
document.write("Hello"); 
//--> 
</script>

The same way you do with HTML. Here is a simple example:

<%
Dim MyName
MyName = "Mike Prestwood"
%>
<script language="javascript">
<!--
document.write('Hi <%=MyName%>')
-->
</script>

It’s like having your own personal operating system you can carry in your pocket.

Paradox for Windows has two primary file types: source files and delivered files. Source files in Paradox are binary but can can be opened in later versions of Paradox and even in earlier versions if you don't use any new features: .FSL = Form, .RSL = Report, .SSL = Script, and .LSL = Library. Since Paradox source files do not compile to an EXE, Paradox developers tend to use a startup form or script to start the application.

Step by step instructions for repairing your Paradox tables.

Using Paradox 9 on XP with CorelDraw or any other programs is fine. No problem there. Not sure what the issue is though. You might want to try starting Paradox with a clear desktop using the -c command line option. You can search the help file for command line options for usage. If that isn't the problem, then you must have a bad installation of Paradox (try reinstalling) or some other program is causing it to crash (doubtfull with XP memory management).

Perl is a loosely typed language with only three types of variables: scalars, arrays, and hashes. Use $ for a scalar variable, @ for an array, or % for a hash (an associative array). The scalar variable type is used for anytype of simple data such as strings, integers, and numbers. In Perl, you identify and use a variable with a $ even within strings

Literals are quoted as in "Prestwood".  If you need to embed a quote use a slash in front of the quote as in \". 

General Info: Associative Array

Languages Focus: Associative Array

Associative arrays are also known as a dictionary or a hash table in other languages.

my %weekdays = (
'Sun' => 'Sunday',
'Mon' => 'Monday',
'Tue' => 'Tuesday',
'Wed' => 'Wednesday',
'Thu' => 'Thursday',
'Fri' => 'Friday',
'Sat' => 'Saturday',
);

my $day_of_the_week = $weekdays{'Mon'};

PHP is a loosely typed language. No variable types in PHP. Declaring and using variables are a bit different than in other languages. In PHP, you identify and use a variable with a $ even within strings!

You assign by reference with & as in &$MyVar.

In PHP you can use quotes, or apostraphies as in "Prestwood", and 'Prestwood'. Use a slash in front of a quote or apostrophe to embed same type as in \' and \".

In .PHPhtml pages, you embed PHP code between <?PHP and ?>.

For PHP, JavaScript, Java,and C++, I prefer to put the first { at the end of the first line of the code block as in the example above because I see morePHP codeformatted that way (and on PHP.Net).

PHP Alternative Syntax

Although I don't like to use it, PHP offers an alternative syntax for if, while, for, foreach, and switch. These code blocks are surrounded by statement ending keywords that all use End with camel caps such as endif, endwhile, endfor, endforeach,and endswitch.

<?PHP

$x = "Yes";

//Simple if

If ($x == "Yes")
  echo "hello world";

//If with a block of code.

If ($x == "Yes") {
  echo "Hello world";

  echo "I am a PHP coder!";

}

?>

In Prism, you specify each class and each class member's visibility with a Class Member Visibility Level preceding the return type. Like Delphi, you group member declarations as part of defining the interface for a class in the Interface section of a unit.

Unlike Delphi, Prism supports a traditional OO approach to member visibility with additional .Net type assembly visibility. For example, private members are truly private to the class they are declared in. In Delphi for Win32, you use strict private for true traditional private visibility.

Prism also supports assembly and protected and assembly or protected which modify the visibility of protected members to include only descendants in the same assembly (and) or publicly accessible from assembly and descendant only outside (or). OO purist might object to assembly and protected and assembly or protected and I suggest you choose the traditional private, protected, and public as your first chose at least until you both fully understand them and have a specific need for them.

Unlike Delphi, Delphi Prism uses the .Net garbage collector to free managed object instances. Prism does not have nor need a true destructor.

In .Net, a finalizer is used to free non-managed objects such as a file or network resource. Because you don't know when the garbage collector will call your finalizer, Microsoft recommends you implement the IDisposable interface for non-managed resources and call it's Dispose() method at the appropriate time.

In Prism you can set the visibility of a member field to any visibility: private, protected, public, assembly and protected or assembly or protected. Prism supports the readonly modifier for member fields which is handy for constant like data. In this case, I chose not to preface my read-only member field with "F" so it's usage is just like a read-only property. Prism also support the class modifier (static data) for member fields. Delphi developers should notice the use of := to initialize a member field (in Delphi you use an =).

Cyborg = class(System.Object)
private

public
  FCyborgName: String;
  FCyborgAge: Integer:=0;
 
  class SeriesID: Integer:=100; readonly;
end;

This page provides an overview of basic language incompatibilities between the Delphi for Win32 and Delphi Prism languages. The focus here is to list language features of Delphi that do not exist in the same form or syntax for Delphi Prism, making it easy for Delphi developers to find the appropriate equivalent syntax or otherwise work around the difference. The goal is not to list new features present in Delphi Prism that do not exist in Delphi, as this would exceed the scope of this page.

No. For existing VCL.Net based applications I recommend you stick with Delphi 2007 until it's time to convert it to Delphi Prism.

The problem with collecting individual items is that the user inputting the item tends to put to much information in tasks and use requirement items and design items only as a secondary thought. When collecting project information, you generally collect a combination of what the customer wants (the requirement), how you want to code it (the design), how to test it (the test script), and even a bit of end-user documentation. Your tendency will be to put all of it in whatever bucket your looking at. A PSDP Artifact puts you on a single page where you can put information into their correct place, their correct bucket.

By using primarily Artifacts, you put yourself in the correct frame of mind while developing that feature from the first time you talk about it through testing it, and artifacts make managing linked items easier (one location to deal with name, category, linked actors, etc.)

You can intialize a member field with a default when declared. If you set the member field value in your constructor, it will override the default value.

Finally, you can use the Shared modifier (no instance required) and ReadOnly modifier (similar to a constant).

 A sub named New. You can overload the constructor simply by adding two or more New subs with various parameters.

Public Class Cyborg
  Public CyborgName As String

  Public Sub New(ByVal pName As String)
