How to requery a listbox on a form from another form

Hi again fellows,

I've got an annoying issue I can't seem to fathom. I have a Main or 'Home' form that has a tab control which houses a listbox, which is based on a query, and shows stocklevels.

From my invoicing form, once I've done my stock update calculations (I'm working on a more elegant solution), I need to requery the listbox on the main form to ensure the stock values shown are up to date.

I've tried 'everything'! Open and close the main form from the invoice form, requery the listbox from the invoice form, requery the listbox once the main form has the focus etc. Clicking my reset button on the main form updates the listbox just fine - I've tried cmdReset_Click from the invoice form (worked in Access 97!), but gives an error in 2007.

Sorry its so mundane, yet long to write out! Can someone help?

Many thanks.

You are welcome.

Note that Form_Frm_main is the reference to class object of your form.

When you open the form, then an object of that class gets added to the Forms collection, with a key Frm_Main. Thats why you can use the notations
Forms!Frm_Main
or
Forms("Frm_Main ")

You can argue that the object in the forms collection is a Form_frm_Main but that within the collection it has been assigned the key frm_Main. (At least that is my basic understanding of the underlying mechanics).


Per default Access only opens 1 object of each form class, but it is possible to have the same form open multiple times, although it requires a slight bit more work.

Stonward:
So to be completely disambiguous about my listbox:
Form_frm_Main.L ist55.Requery is about as explicit as I can get I think.
Good answer, but strangely, more helpful information would be where it is relative to the code that's running. If, as seems likely, the code is running from somewhere on the same form (within that same form's associated module) then referring to it using an external reference is not to be recommended at all. That simply adds to your maintenance overhead, and is easily avoided using the Me reference.

Thus, in that scenario (Most definitely doesn't work from outside of the scope of that same form.) the code would be :
Expand|Select|Wrap|Line Numbers
  1. Call Me.List55.Requery
NB. The external reference will still work of course. It is simply an overly clumsy way to code it in those circumstances.

NeoPa; You've just taught me something new. I didn't know you can call a method like that. Be assured I'll be using that!

Many thanks again,

Very pleased to hear it :-)

I find most of my event procedures start with With Me and end with End With. If you don't know about With then that's another you would probably benefit from picking up.

My Main form acts as a Menu. It has 3 CmdButtons which directs to 3 Forms (Form 1, Form 2, Form 3). Form 1 also directs to the next, etc. My problem is that when I Click on the CmdButton that opens Form 1, Form 1 opens fine and ListBox displays info, BUT when I click on my CmdButton on Form1 that opens Main Form and then click on the CmdButton that opens Form1, Form 1 opens BUT says that the data in the listbox are deleted.

Hi, I've got a listbox on a form that gets updated by opening another form for data entry. Once the user enters the new item name and clicks "accept", the data entry form closes and the original form with the listbox displays. I'm having trouble getting the listbox to reflect the additional entry. If I close the form and reopen it, the new item displays just fine, but I know that there is a more direct way to force the listbox to...
