apologise for asking trivial question.

I have gone through the various instructions in the NG and other pages by
MVPs. still there are many doubts.

this may be a trivial example

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'comment-some cells are in bold font
Application.EnableEvents = False
If Target.Font.Bold = True Then
Range("a20").Clear
Range("a20") = 12345
Else
Range("a20").Clear
End If
Application.EnableEvents = True
End Sub

why does the change of cells not fire the event procedure.
where is my mistake.
If I want to debug at what line should I introduce a breakpoint.(I learnt it
should be inthe first execuable statement)
when I use the if statment as for example
if target.value 4 etc the event procedure is fired

of course in standard module it works.
thanks and regarads.

The procedure works for me - XL2000, winXP.

Did you put the code in a worksheet module? It won't fire unless it is in
such a module.

There is a good chance in your testing, you experience an error in the event
procedure. At that point, you had
Application.EnableEvents = False
so when the error stopped execution, the events were never turned back on.

Put in a sub in a general module

Sub SetEventsON()
Application.EnableEvents = True
End Sub

then you can turn events back on if you start having problems.

Also, when testing you can put a msgbox command as the first line. Then if
the problem is really a poorly written If statement, you will still know
your event is firing.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
msgbox "In SelectionChange, Target: " & Target.Address(0,0)
'comment-some cells are in bold font
Application.EnableEvents = False
If Target.Font.Bold = True Then
Range("a20").Clear
Range("a20") = 12345
Else
Range("a20").Clear
End If
Application.EnableEvents = True
End Sub

Once you get through debugging your event, you can use error trapping to try
to ensure events are always enabled:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
On Error goto ErrHandler
'comment-some cells are in bold font
Application.EnableEvents = False
If Target.Font.Bold = True Then
Range("a20").Clear
Range("a20") = 12345
Else
Range("a20").Clear
End If
ErrHandler:
Application.EnableEvents = True
End Sub

thank all of you MVPs for giving me some idea. I would test the seteventson
sub for debugging.

In the meanwhile I found my mistake. I did go the worksheet code by
rightclicking sheet tab and clicking view code. therein I must have
forgotten to click the worksheet and the code statements were wrongly
originally parked under <general. when I cut and paste the statements
under worksheet it works fine. sorry for the trouble. I was misled because
the stataements were threre both under general and worksheet.

for debugging I will follow the seteventon sub given by Mr. Togilvy;.

I got some(only some) of the cobwebs cleared. I am still on learning curve


thanks and regarads.
