Delphi Prism Language Details

Same as VB. The Me keyword is a built-in variable that refers to the class where the code is executing. For example, you can pass Me from one module to another.

Private Sub Command10_Click()
    MsgBox Me.Name  'Displays name of form (Form1 in this case).

End Sub

Same as VB. The Me keyword is a built-in variable that refers to the class where the code is executing.

Class Cyborg
 Public CyborgName
 

 Public Function IntroduceYourself() 
  'Using Me. Prints Cameron.
  Response.Write("Hi, my name is " & Me.CyborgName & ".")

  'The above is just a demo. You could also not include "Me." 

  'in this case because we are in context of Me now. Using Me 

  'makes more sense when you start to pass Me as a parameter 

  'to a method.

 End Function 
End Class

To refer to the current instance of a class, use the this keyword. The this keyword provides a way to refer to the specific instance in which the code is currently executing. It is particularly useful for passing information about the currently executing instance.

The this keyword is also used as a modifier of the first parameter of an extension method.

You cannot use this with static method functions because static methods do not belong to an object instance. If you try, you'll get an error.

A built-in object variable that represents the UIObject to which the currently executing code is attached.

Syntax Example:   method pushButton(var eventInfo Event)   msgInfo("", self.Name) endMethod

Within the implementation of a method, the identifier Self references the object in which the method is called. The Self variable is an implicit parameter for each object method. A method can use this variable to refer to its owning class.

ShowMessage('Self=' + Self.ClassName);

The Me keyword is a built-in variable that refers to the class where the code is executing. For example, you can pass Me from one module to another.

Private Sub Command4_Click()
  MsgBox Me.Name 'Displays name of form (Form1 in this case).
End Sub

To refer to the current instance of a class or structure, use the Me keyword. Me provides a way to refer to the specific instance in which the code is currently executing. It is particularly useful for passing information about the currently executing instance.

The Me keyword is also used as a modifier of the first parameter of an extension method.

You cannot use Me with static method functions because static methods do not belong to an object instance. If you try, you'll get an error.

Syntax Example:   Sub SetBackgroundColor(FormName As Form)   //FormName.BackColor = ...some color End Sub   //Pass Me. SetBackgroundColor(Me)
