How To Trigger After Update Event
Nov 4, 2003
Thanks to S.baxter I have used some code to loop through a recordset and select each record in turn in a form that uses the recordset as the Rowsource of a combo box. However, there is an After_Update event attached to the combo box which is not being triggered.
MS Help says :- "If you move to another record or save the record, the form's BeforeUpdate and AfterUpdate events do occur." I have tried this but can't get it to work. Would it work if I could move the focus to another control on the form and if so how do I do that?
Thanks

Hi,
I use access database for a website. I would like to run a trigger in a specific table when updating a record.
Is it possible to create table level triggers in Access at all, if it is, pls. give me short direction. (as far as I know there are lot of events, but this events occur only in native access application only, and can not be handled outside of access, am I right?)
thanks a lot

I am updating a value in an unbound control on an unbound form. When the value in the control is changed I want a sequence of code to execute. Specifically changing the record source of a subform and refreshing it.
The problem I have is that when the value of the unbound text box is control is changed (I am using a button to change the value as a test) the after update event on the text box does not do anything.
I did a simple test using a button to change the value in the text box and in the afterupdate event of the text box asked it to output the value of the textbox to a message box as shown below.
The problem is this does not work, nothing happens. If I tab out of the text box or change the value with the keyboard however the msgbox appears. Just not via a vba change.
Code:
Private Sub Prod_ID_AfterUpdate()
Dim pid As String
pid = Me.Prod_ID
MsgBox pid
End Sub
Private Sub Button_Test_Click()
Me.Prod_ID.SetFocus
Me.Prod_ID = "TEST"
End Sub

There are around 100 customers.And on application open, need to check if customer has paid invoice. If the customer has paid/not paid need to change the status accordingly. Form on open event changes status of only the first customer.Form on current changes status only if we move to the specific record. Is there an event to trigger to check the entire table records on application open?

I have a main Part form and a Spec subform linked via Part key.
I need to add 6 Spec records automatically when a new Part is added so user can select desired Specs (default value is "n/a" for al 6 entries).
Right now I have the Spec entries added in AfterInsert for Part form, but I have to navigate out and back into record to trigger Part insert. I cannot add the Spec entries until the Part entry is added.
Is a command button my only option? Or is there another way?
AfterInsert is too late, and BeforeInsert is too early; that gets triggered as soon as the first character is typed in Part name.

Basically, I have progress table with learners and each learner must undertake 4 tests. Once they have completed each test, in the original learner table, I want it to show that they have completed the task if all 4 boxes are checked by it triggering one final check box.

I've got a subform that im writing code for, once a user enters a value in one of the fields i want to make sure they cant change that field (and two other fields in that same record, though the rest of the fields are fine to edit at will)
I've got a function already written to validate the data in the record and decide whether or not the fields are enabled and disabled, however im having trouble finding an event in which to activate the function
Is there an event that triggers whenever a user selects a different record?
Any chart or list with all the handlers and how they trigger (in relation to each other) and when?

How to structure some MS Access 2007 Forms for the following scenario.
My table structure is as follows:
Product
++++++
ID (pk)
ProductName
...
Tag
++++
ID (pk)
TagName
ProductTag
+++++++++
ProductID (fk)
TagID (fk)
I want to have a main form that allows me to search for and displays a list of all products (and the dozen or so attributes for each product) that meet that criteria (I'm thinking a continuous form view of products).
So far so good. No problems.
Now I want a "tagging" form to the right of my continuous forms product list that is linked to the product which currently has focus. The tag panel should always show a complete list of all Tags. I want a checkbox next to each tag that I can switch on and off whether that tag applies to the currently selected Product. I also want to be able to add tags on the fly (without leaving the main form).
I think I have three forms in play :
Main Form
Product Form (subform to Main) my product search criteria is probably on this form header.
Tag Form (also subform to Main)
But with this approach I'm have trouble linking the two sub forms to each other. Actually, I'm having huge trouble figuring out how to display the list of all tags with a check box that when checked on and off creates / deletes a record in the ProductTag table and I really want Access to do as much of the CRUD as possible. I would prefer to avoid writing screeds of SQL INSERTS/DELETES on events. Am I asking too much of Access?

Hi,
In Form of the MS Access.
How can I make the form cannot close if the field is Null when I click the close button?
frm1:
Field Name: Date, Id, Name
The 3 field names are required to input.
Before Update Event:
if (isnull(date)) then
date.setforce
end if
if (isnull(id)) then
id.setforce
end if
if (isnull(name)) then
name.setforce
end if
It works well when I go to next record (suppose I miss one field)
However, It doesn't work when I click the close button, the form is closed.
I want the form cannot close until fill out all fields. It cannot go to the missing fields.
I have a question, when I click close button, Must the form be closed even though I set up the field to be "setforce"?
Thanks.

Hello All,
I have a question.
Can I have in Access 2000, in the After update event a code like this:
DoCmd.RunSQL ("Update Table1" & _
"SET [Table1].Field1 = (SELECT DISTINCT [Table2].[Field1] FROM [Table2] " & _
"WHERE [Table2].[Field22]= "& Me.textbox & " And (Left(Field1,5)= "00000" ")")
?
I have 2 tables. Based on what the user enter in "Textbox" I want to query Table 2 (with conditions) and to update Table 1 with the value I found in the Select statement. (Table 1.field1 = table 2.field1)
Thank you.

I need to trigger an event for when a text box is updated.
However, I cantuse on_update() because the text box is updated by dlookup (and on some of my other ones by vb code), and on_update() only works when the user physically enters a value.
Which event should I use. If there isnt one, is there a work around?

I need an event for when a text box is updated. Not by the user typing into it, but when VB code or something like Dsum() changes its value automatically.
What event can I use? Does one exist for this?

Hi
I have form with a series of text boxes in which users can edit the data that is populated in them. For one of the text boxes I want to add an after update event, so that if the user changes the value in the text box, a message window appears telling them to click on the submit button at the bottom of the form.
Does anyone know the code that I should use to make this message appear when the value in the text box is changed?

I have a DB with TblInspector and TblViolation Data. Here is what I am having trouble with. On my form I have a combo box named Inspector and a text box named ARNumber. What I would like to have happen is anytime that I select John Doe from combo box Inspector it pulls his ARNumber from TblInspector and saves his ARNumber in TblViolation Data.
I have fields Inspector and ARNumber in my TblViolation Data. I am pretty sure it is an After Update Event. I just don't know what code to put where. This is what I currently have on my combo box. It pulls the number and displays it in the text box on the form but does not save it to the table.
Private Sub Inspector_AfterUpdate()
Me.ARNumber = Me.Inspector.Column(1)
End Sub

I have a form which displays information in the footer until the use has accomplished some tasks. Once I verify that all is well I allow the user to change the fields in the footer. I want to verify that the proper changes were made but the BeforeUpdate event does not fire until the form is closed.

I have a query in a subform on the main form. I have a search box that updates the subform/query as you type something (using the On Change event). You then click on the record you want which transfers the information to the appropriate text boxes (one of these txt boxes is the clientID I talk about below) located next to the search box.
I have a Contacts subform/query much like the serarch box I created and I am using a txt box (on the main frm) clientID (which I get from the above process) to filter the contacts.Now when I pass the ID to the txt box on the main form I am having trouble getting a event to trigger and update the subform/query correctly.
I am using VBA to create a simulated Click action which seems to work but is not updating the Contact subform/query, it is just resetting the subform/query. If I manually click on the txtbox with a ID in there all works wonderfully. I have attached the database. I made the clientID and btn next to it visible(this would not be visible normally).I just realised I left a button on the main form next to the clientID txt box just ignore that and click on a client then the clientID txt box to see how it updates the contacts subform..

I am trying to use a Combobox BeforeUpdate Event to achieve a required result.
I have two combo boxes inside a frame. The first is a year number 2011, 2012, 2013, 2014
The Second is the Week No ranging from 1-52, but 1-53 in some cases and this updates accordingly with the year number selected.
When the user has selected Week 53 and then changes the year to a year where only 52 weeks exist I want to Cancel their event.
I have already made a function to determine if 53 weeks exits however when I come to do the Cancel Event, the combobox for the year doesn't change back. It stays on the users new selection.
Below is the code that I am trying to use:
Private Sub cmbWeekNoFromYear_BeforeUpdate(Cancel As Integer)
If UpdateWeekNoSelections Then
Cancel = True
Me.cmbWeekNoFromYear.Undo
End If
End Sub
'cmbWeekNoFromYear is the name of the combobox which holds the year number
'UpdateWeekNoSelections Simply returns True if I want the users change cancelled for cmbWeekNoFromYear

On a form I have a pair of controls, Price and PriceInUSD. If the user enters a new value into the Price field, then its AfterUpdate event fires, which looks up the relevant exchange rate and updates the PriceInUSD control accordingly. That all works fine.
Now in some circumstances (if a checkbox elsewhere on the form is checked), I generate a modal dialog box asking the user to confirm that the Price value is correct, or enter a new value.
That modal dialogue box's Enter button's On Click event then updates the Price control before closing the dialog. That bit works fine, too - but I had thought that this update of the Price control would fire its AfterUpdate event - but it doesn't.
So, my basic question is : do Control events only fire in response to user input, and not to programmed changes ?

I have an order form with an order details sub form. Both are bound to their respective tables and function correctly, with the OrderID being inserted automatically into the order details table.
However I am using VBA to update and check stock and have it working when attached to a separate form called process orders. Which event would be the best place to place this code. I do not really want to have the process orders form. Would it be on the master form or the sub form. I thought of placing it in the after insert event on the subform, but there can be many order items per order and it will run before I have finished adding order items. I tried it in the after insert event on the master form, but I think that this will run the code too soon as at this stage the order details will not have been written to that table.

First 3 letters of surname + first 3 letters of forename + DD + YY (Date of birth)
I can use the after update event to update the primary key field but it won't get saved for some reason so have I missed something?
