[AccessD] Retrofit form issue

If the subform is always only a subform and others are forms, you can pass 
in a delimited list of elements that include Parent form name, subform 
control name and add a .form.

The bigger problem arises when you have multiple instances of a form that 
runs such a procedure.  In that case, you need to pass in a reference to the 
calling form itself, or better yet, references to the controls that have 
properties to be set in the input form.  If you want to use a modal/dialog 
form (it can be pop up without being modal), which you would in the ordinary 
course of events for this kind of interaction, then any code which opens the 
input form pauses as it calls 'OpenForm' so it is not possible to pass in 
anything but strings in OpenArgs.  An alternative is to open the form as a 
pop up and disable or hide other open forms.  In that case, the code that 
opens the input form can pass in object variables to its own controls via a 
public procedure or a property procedure on that input form in the lines 
immediately following the OpenForm call.  That will work no matter what 
level of subform nesting or which or several open instances of a calling 
form is involved.

A hack solution to allow use of a modal form is to use broadly scoped 
variables and set them immediately before opening the modal input form.  The 
modal form should clear them in clean up when it closes to cut down on scope 
contention issues.  Just make sure you don't use these variables for 
anything else.
