[AccessD] Dim fm as form or fm as Form_ rmCert

I cannot say what exactly is going on, but I can say that...

>I've learned the hard way that whenever I open an instance of Excel EVERY
object variable must be set to nothing because Access cannot be relied upon
to cleanup properly.

No, you need to clean up EVERY object variable regardless of the object
type.  Access' garbage collection is not reliable and you will end up with
all kinds of weird symptoms if you don't clean up behind yourself.

Subject: [AccessD] Dim fm as form or fm as Form_ rmCert


In a module I referenced an open form as follows:

dim fm as Form_frmCert 
Set fm = Forms!frmCert
....do stuff using txt values on the form
run Excel, place the text values in ranges on a worksheet
etc
	If Not (wb Is Nothing) Then Set wb = Nothing
    	If Not (fm Is Nothing) Then Set fm = Nothing
	appExcel.Quit
    	Set appExcel = Nothing

When the function finished an instance of Excel was still running.when I
changed the dim statement to read
	dim fm as form
the instance of Excel terminated properly. I've learned the hard way that
whenever I open an instance of Excel EVERY object variable must be set to
nothing because Access cannot be relied upon to cleanup properly. However,
I'm curious what is going on here. Why does fm not go out of scope?
