How to Pop up message in Excel?

Why not just protect the sheet with a password. Once done, none of the cells can be edited at all, except for cells you specifically remove protection from prior to protecting the whole sheet.

Actually, I need to do this for perticular cells.
Moreover , this is just a case, so as to get the programming way to understand.
There are other things need to be done for some other cell like -
To pop up a window saying "Please make same changes in so-n-so file as well!" after the cell value is changed.

I hope I'm able to state what exactly I want.
If it's not clear , plz let me know.

Thanks.

Plz refer to the redefined issue.
Thanks.

What are the particular cells?

JBeaucaire is the best answer, here is a code that will do what you want

Private Sub Worksheet_Change(ByVal Target As Range)
    MsgBox "Please do not Change this"
    Target.Select
End Sub
