[AccessD] SubForm and form

I wasn't talking about the sequence when the subform loads, which
happens before the load of the parent form.  I'm talking about the code
behind the event you're monitoring, like a button click event on the
subform.

Thanks Charlotte - that's just what I need.

And I've always seen the subform's code run first - and it always runs
twice for some reason.

No, what I posted was for an independent popup form.  A subform is a
little different.  The difference would be that you would declare your
variable as a subform and set it to Me.mysubform.Form to give you access
to the events of the subform itself, not just the subform control.  
 
Then, in the IDE dropdown where you see the controls of the parent form,
you will also see your "withevents" subform object, i.e., mySubform.

Dim WithEvents mySubForm As Form 

In the Open or Load event of the parent form, do this:

	Set mySubForm = Me.mysubform.Form

The easiest way to create the shell is to select the mySubForm object in
the controls dropdown and then select the event you want to intercept.
VBA will create the shell with the proper signature and all you need do
it add the code you want to run for that event.  Please note that is you
also have code in the subform for that event, both sets of code will
run, although I don't recall which set runs first.

Charlotte,

I know I'm dense on this.  

The form you're setting - is that being done in the Main form's module
and myForm is a subform in that main form?

How do I create the 'shell' routines?

All you need to do is declare a form variable at the module level
WithEvents, like this

Dim WithEvents myForm as Form 

That will give you a myForm object in the list of objects in your form
and if you select myForm from the dropdown list, you'll be able to
create shell routines to handle any of the exposed events of a Form.
So you can have a myForm_Load event, for example, which would contain
code you want to run when myForm is loaded.

John,

Believe it or not, I initially figured that this could be done because I
do try to learn from your postings! :-)

I gave my suggestion simply because that's what I know how to do.

Could you post a short example code of how you would set up the main
form's monitoring of the subform's events?  I sure would like to manage
a subform's load and open events.

Thanks!
Dan

You can also declare a pointer to the form WithEvents and then sink any
of the form's events in the main form.  Doing that allows you to see the
subforms events from up in the main form and select them.  When you
select one of the events, VBA creates an event handler up in the main
form.

Click events and enter/exit events usually do not have a problem but you
should remember that subforms load before the main form's class module
so events like OnOpen and such cannot reference code up in the main form
until the main form's class has finished loading.

Hi All:

I just can not remember... too tied... too old. But how can a 'click' on
a field within a subform be monitored and can subsequently produce a
result on the main form?

TIA
