I have an Access form with a couple of buttons that I want to disable based on the drop down selection of another field.
When the Status dropdown is set to "Closed" I want the "Add" buttons to be disabled, disappear, or inactive for people to use. I also need the buttons to be reactivated if the job is reopened.
I thought I would use the OnCurrent attribute but so far I can't figure out the correct code to make it happen.
Thank you.
Place code in form Current as well as combobox AfterUpdate events.
Me.buttonname.Enabled = Me.comboboxname <> "Closed"
Or use Visible property if you prefer.

I need few suggestions/workarounds. I am having an issue on user experience of ngx-bootstrap inline datepicker.
If the user selected the date range on the same day, some user only click once. The problem is bsValueChange only emit when click twice. So when the user click the apply button on the screenshot, it applies the previous value. What i want to do is if the user did not click twice, i disable the apply button but the v5.3.0 does not have an event emitter for that situation.
Thank you

Hi I would suggest you add some external buttons with some predefined date ranges like in here. quick dates with buttons
Then you can just hook it to a click event and in the method you set the bsValue input to [m().subtract(0, 'days').startOf('day').toDate(), m().endOf('day').toDate()]; where m refers to momentjs.
I have a Tab Control element containing 2 tabs: Tab1 and Tab2. Tab2 contains a ListBox element whose RowSource queries the data that gets submitted in Tab1.
Say the user opens this form containing these 2 tabs. They are originally on Tab1. in the Form_Load event for Tab2, it queries the data it needs to populate its ListBox. Now they switch tabs to Tab1. They enter some data and submit a new record to the corresponding table (the same table that the Tab2 ListBox uses as its RowSource). When the user switches back to Tab2, they don't see this newly added record.
What I have done so far is that when the user clicks anywhere in the ListBox, it calls Requery, and then the record will show up. This isn't enough as it's not intuitive for the user to have to click on the listbox to update its contents.
I have tried putting this Requery code in a Form_Load, Form_Activate, GotFocus, but nothing works. I know you can detect the TabControl clicks, but how can I access the forms and the elements that they contain?
Any ideas on how to requery this listbox whenever the tab gains control?
If you want to add code for a specific tab on a tabcontrol, the most convenient way to do that is to write code in the TabCtl_Change event. That occurs when the tab control is changed. E.g.:
Private Sub MyTabCtl_Change()
If MyTabCtl.Pages(MyTabCtl.Value).Name = "Tab2" Then 'The tab control just changed to your page
'Requery that list box
End If
End Sub
Note that, if you're not using a tab control at all, but a navigation control (which it does sound like, tab controls don't necessarily have subforms on them, and don't have Form_Load events, forms do)
You're most likely looking for the On Activate trigger.
Then, in the code just use Form.Requery or Form.Recalc depending on which you're actually looking to do.
Alternatively, you could use the same control the user is using to submit records to trigger a requery. Although, that would require a specific Form to be called into focus.
We've got a checkbox on a form that we'd like to be able to check/uncheck even whilst the form is opened as read-only (it's a sales/product form and when an order has been invoiced, we want to prevent changes).
I know I could add a command button in its place and even make that button look like it's a checkbox with some images, or even set up a key combination to be used instead of the checkbox, but first I'd like to know if it's possible to simply exclude one checkbox from being read-only on a read-only form.
No. You must go the other way around:
Make the form read-write, then disable all controls bound to data fields except this single checkbox.
I have form that displays information on a project. Most of the fields on the form are bound to a Project table and display and update as bound fields do. However, I also have 10 checkboxes that come from a ProjectAudience table. Only if the box on the form is checked, is there is a matching record in the table. Therefor, I need to insert and delete records as these boxes are checked and unchecked.
I can do it at the checkbox level with the AfterUpdate event, but that would require 10 different events. I looking to do it at the Form level by deleting all records in the ProjectAudience table for that project and adding in the checked ones.
Basically, I'm looking for the opposite of the Form_Current event that will fire when either the record navigation button is fired or the form is closed. I'm trying to avoid either writing my own navigation buttons or adding a "SAVE" button to the form that the user must press. I want something automatic that will update this table when the user navigates away from the record.
Based on a comment below: Any combination of boxes from none to all can be checked not just a single box. Therefore, it is possible that I would wipe out all records and not insert any back... or add 10 records if every box was checked. (Also, I am using Microsoft Access 2003)
Have you considered adding these checkboxes to an Option Group and using events from that group?
EDIT re Comment, Alternative approach, do not use an option group, but add code to an event line for all relevant options.
You do not need code for 10 different events, you can set the event line for, say, On Click to the name of a function, let us say:
On Click : =TestMe()
Event Line http://ltd.remou.com/access/EventLine.png
You then need a function:
Function TestMe()
MsgBox "You clicked " & Screen.ActiveControl.Name
End Function
You can use the BeforeUpdate method. However, if only the checkboxes have been changed this event will not fire since the record to which the form is bound didn't change.
I would advise to link events to the checkboxes. Create a function UpdateCheckbox(CheckboxID as integer) that does what you want and put this in the 'OnClick' event from the ckeckboxes: =UpdateCheckbox(1). Change the 1 for the different checkboxes.
I have multiple combo and option boxes whose visibility is set true or false depending on user selection of other parent option boxes.
I am using the AfterUpdate() function for the parent option boxes. This method has been working fine.
However when I set the values of the option boxes in VBA code (Me.MyOptionBox = 1), there is no "update" to make the child option and combo boxes appear. It works when I manually click on the option, but if I set it in the code nothing changes except for the option box selection. It doesn't make sense to see the option box set correctly but the code responsible for checking which option is selected not work.
Does anyone have any ideas on how to get around this? I just want the form to be updated once I set the values of the option boxes. What is the "update" that AfterUpdate() is referring to anyway?
I have tried MyForm.Repaint and MyForm.Requery but these do not work either.
Any ideas?
You can call the OptionBox_AfterUpdate() method directly - after you set the values.
I'm pretty sure this is intentional. The problem is avoiding circular recursive updates, when you consider that a control can be changed by a user and by two forms of code (explicit and bound data).
For bound controls, changes in the data change the controls.
For user input, changes in the control change the data, plus whatever dependendencies you explicitly specify in events.
For changes caused by your code, the assumption is that you need to manually apply all the consequences of the state change you are coding.
If you are using bound controls, you can change the datasource and have the consequences applied automatically.
In VBA, most control events do not fire when the control is updated programmatically, rather than manually. You must specify the code that is to run after the programmatic update.
By "I am using the AfterUpdate() function," you mean you added an event handler for the AfterUpdate event, right?
If that handler is not firing when you expect it to, you could always call your handler directly (instead of letting the event fire it) where necessary. But that probably wouldn't be the best way of doing it; more likely there is another event that should be calling your handler instead of or in addition to AfterUpdate. I don't remember the names of combo box events, but isn't there something like ItemChanged or SelectionChanged or something?
