How do I define some event in a cell ?
Like, after I entered a string in a cell and press ENTER, something need to
be done like calculation, or fetch data from a file. Is it a macro ?

It is a procedure tied to the event. The example below shows the value you
have just entered, as an example

Private Sub Worksheet_Change(ByVal Target As Range)

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range("A1:H10")) Is Nothing Then
With Target
Msgbox .Value
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.

By the way, can you tell me how to determine the position of the cell which
triggers this event please ?
As I don't understand your code.
