What is early binding and late binding

Answer Posted / prasad sethuramalingam

BINDING :A process when an object is assigned to an object
variable.
EARLY BINDING:
An object is early bound when it is assigned to a variable
declared to be of that specific object type. Early bound
objects allow the compiler to allocate memory and perform
other optimizations before an application executes. For
example, the following code fragment declares a variable to
be of type FileStream:
' Create a variable to hold a new object.
Dim FS As System.IO.FileStream
' Assign a new object to the variable.
FS = New System.IO.FileStream("C:\tmp.txt", _
System.IO.FileMode.Open)
LATE BINDING:
By contrast, an object is late bound when it is assigned to
a variable declared to be of type Object. Objects of this
type can hold references to any object, but lack many of the
advantages of early-bound objects. For example, the
following code fragment declares an object variable to hold
an object returned by the CreateObject function:

' To use this example, you must have Microsoft Excel
installed on your computer.
' Compile with Option Strict Off to allow late binding.
Sub TestLateBinding()
Dim xlApp As Object
Dim xlBook As Object
Dim xlSheet As Object
xlApp = CreateObject("Excel.Application")
' Late bind an instance of an Excel workbook.
xlBook = xlApp.Workbooks.Add
' Late bind an instance of an Excel worksheet.
xlSheet = xlBook.Worksheets(1)
xlSheet.Activate()
' Show the application.
xlSheet.Application.Visible = True
' Place some text in the second row of the sheet.
xlSheet.Cells(2, 2) = "This is column B row 2"
End Sub
