Hi Stuart,
Thanks for response. I follow what you are saying. In a little demo app
link posted on Access-Programmers by ChrisO, I saw the code (below) for
building a more generic function for handling/building a function to assign
to an event. The referencing of me.activecontrol didn't cross my mind in
your suggestion, makes sense though.
So I understand about storing Button,Shift/X/Y in variables local to the
form that you mention and then referencing them within routines in the form.
My question relates to the "populate these in the MouseDown" comment. How
do I generically reference these Button/Shift/X/Y variables from the Mouse
Up/Down/Move events? If I were to create a procedure at Design time in the
on mouse down event of a textbox control, it would be foo_MouseDown(Button
As Integer, Shift As Integer, X As Single, Y As Single). That's where I'm
having a brain freeze, on how to reference these from a generic procedure -
maybe from the storm kicking in here in the Boston area...
Thanks,
John

End Function

Hi John,
Welcome to the list.
Instead of "=TxtBoxDblClick([Txt101])", you can just use
="TxtBoxDblClick()" and then in
TxtBoxDblClick, just refer to Me.ActiveControl.
You can do the same with your other functions.
You can make your Up/Down/Move functions even more generic you using
something like:
Select Case Left$(me.activeControl.Name,3)
Case "txt" ' It's a text box
...
Case "cbo" 'It's a combobox
...
You can store Button,Shift/X/Y in variables local to the form
Dim intBtn As Integer
Dim sngX As Single
Dim sngY As Single
Dim intShift As Integer
and populate these in the MouseDown

John,
I found another link that is more focused on your drag and Drop.
http://www.access-programmers.co.uk/forums/showthread.php?t=238669
>From post #5
"I really do not have a meaning of beginner/intermediate but do have some
classes broken down into minimalistic form on my SkyDrive in my signature.
It?s a developmental sequence of classes used for ?drag and drop? running:-
Drag Drop -> Drag Drop Resize -> Drag Drop Resize GridSnap -> Drag
DropResize GridSnap Save.
Some end applications for drag and drop, also on my SkyDrive, are:-
Drag Floor Plan, Drag Polygons, Z Order Bound Objects and Drag and
DropChess."
Good luck

Hi John,
Welcome to the list. We have a webpage too.
http://www.databaseadvisors.com
On that Webpage is some code samples.
One in particular that shows one way to accomplish some elements of Drag and
Drop in Access.
Check it out at:
http://www.databaseadvisors.com/downloads.asp
And look for "Drag and Drop".
Hope it's useful.
Darren

Subject: [AccessD] Generic Procedure on form controls for Drag and Drop
Hello,
New to this list and need some guidance on a form I've developed (I posted
this on LinkedIn and got a few links with good information, but still having
issues).
I have a grid of many text boxes on a form in an Access 2003 app that I fill
from a table upon opening the form as well as when the user changes a date
box. I add some generic procedure calls on the fly to each text box where I
pass the control to the generic function (for instance, I'll add a
double-click event to text box "Txt101" as "=TxtBoxDblClick([Txt101])". This
will pass the control to my function TxtBoxDblClick so I can react to it.)
This all works fine for all text boxes and I reference just one (same)
routine for each control.
I'm trying to experiment with Drag and Drop and found some code that I can
get to work if at Design time, I add three event procedures to a text box
control (Mouse Down/Up/Move). If I do this to two different controls,
creating 3 event procedures for each at design time, I can successfully drag
and drop between the two controls. So the drag and drop code looks like it
works.
My problem is, I want to have 3 generic routines like my TxtBoxDblClick
function, that I can add on the fly to the On Mouse Down/Up/Move events and
I can't figure out the syntax and/or code to make this happen. I can add the
custom Functions no problem, but I know I need to be able to deal with the
Button, Shift, X & Y parameters somehow. I can pass the control to the
custom function, but am unable to reference the Button, Shift, X & Y
parameters. I'm guessing I'll need to create some type of class possibly? If
so, can someone provide some sample code on how to do this what the calls
would be? Thanks for any ideas. John

This sounds like the perfect use for a class. A class can Sync events. A
class is used when you have to do the same thing over and over. The event
sinks you mention would be embedded in the class and the code to process
the event sinks would be embedded in the class.
I left my computer at work so I can't look at this right now. In the
morning I will respond further.
