1.
2. Most people's first introduction to Excel
macros is through the use of the
recorder facility which generates a
VBA macro that the user can then
manually launch. Some people then
graduate to editing recorded macros
and perhaps writing their own code.
3. As well as writing macros, Excel VBA
also supports the creation of event-
handlers which will execute when
certain events take place in the Excel
environment.
4. The easiest event handlers to create
are those which relate to workbooks
and worksheets.
5. When you enter the Visual Basic Editor
(VBE), the Project Explorer displays a
series of icons representing each open
workbook and, nested inside each, the
worksheets they contain.
6. These icons represent workbook and
worksheet objects and Excel VBA
allows you to enter special subroutines
called event handlers directly inside
them.
7. To create an event-handler, simply
double-click the icon representing the
worksheet or workbook in which you
would like to place the event handler.
8. This opens the code window at the top
of which two drop-down menus are
displayed, the one on the left labelled
"General" and the one on the right
"Declarations".
9. Click on the drop-down on the left and
choose "Workbook" or "Worksheet",
depending on which object you are
editing. The drop-down on the left will
then display all of the events available
for event-handlers for that object.
10. Choose an event from the list and
Excel will automatically create and
event-handler subroutine with the
appropriate name. For example, if the
object is a workbook and you choose
the event "Activate", Excel will create
a subroutine called
"Workbook_Activate".
11. In addition to workbooks and
worksheets, event-handlers can also
be placed inside Excel UserForms and
all of the objects they contain. To
create a user form, simply choose
UserForm from the Insert menu then use
the Toolbox to add controls to the form.
12. To create an event handler for any
item you add to the form, simply
double-click the object to open the
code window for the form. Excel will
then create the default event-handler
for that object. If this is not the event-
handler you wish to create, choose a
different event from the drop-down
menu in the top right of the code
window.
