Modules & VBA :: Update Value In Unbound Control Then Trigger Event?

Feb 4, 2015

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

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

How To Trigger Access Table Update Event

Jan 5, 2005

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

Modules & VBA :: Event That Trigger On Selecting A Record Of Subform

Jun 30, 2014

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?

General :: Populate Unbound Textbox With Combo Box After Update Event

Nov 13, 2012

I am populating a table using combo boxes in a continuous form. The box box alone works fine without any issue of repeated data. But as you know obviously the combo box only populates data in a single column of the table, in which case mine is the LASTNAME; so now I am attempting to populate a unbound textbox with the FIRSTNAME side-by-side with the combo box for the same record.

In the After Update event of the cboLASTNAME:

Code:
Me.txtFIRSTNAME = Me.cboLASTNAME.Column(3)

However, after updating the the combo the textbox data is repeated.

Is there a possible solution to this?

Forms :: Control Update Event Not Firing

Jul 4, 2014

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 ?

Modules & VBA :: Click Event To Open A Form And Select Record Corresponding To Value In Unbound Text Box

Oct 29, 2013

I have some code for a button on click event to open a form and select the record which corresponds to a value in an unbound text box. The code is:

Private Sub Command25_Click()
On Error GoTo Err_Command25_Click
Dim stDocName As String
Dim stLinkCriteria As String
stDocName = "frmOpenPatientRecord"

[Code] ....

This works fine when I put in a 10 digit NHS number but opens a blank record when I enter a four digit or six character/digit PatientNumber. Both patient number and NHS number are text fields in the underlying table.

General :: How To Trigger Form Insert Event

Mar 7, 2014

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.

Modules & VBA :: 4 Unbound Controls Require Data - Validation Event Triggers Without Command Button

Aug 13, 2015

There are 4 unbound dropdown list box that will have a default value of empty string. All 4 must have values entered (data is required).Once all 4 are required - the bottom 5 text box will become enabled (optional data).Forcing the user to click on a Validation Button

Some users type then use the mouse to select the next.Other users type to select then tab.The trick is: After filling in the 4th listbox and validating all 4 have values, the event must trigger code to enable the 5 optional text boxes below.This provides a seamless data entry environment.

I have been doing this in other places, but the transisition after the last required field is complete gets ugly.If Trim(cmbBoxname1 & "") = vbNullString ' check all 4..If it is the 4th one, the event seems not to happen quick enough for the bottom 5 text boxes to be enabled so the user can continue with data entry.

Forms :: M2M / Master Child Form Design - Trigger Event?

Oct 14, 2013

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?

Modules & VBA :: Assign OnClick Event To Control Through Code

May 27, 2014

Visual Studio IDE environment and I have been working with Access VBA for almost a year now.

I am very used to generating my form controls in runtime and being able to create some cool user interface interactions by being able to say btnExample.OnClick += MyDynamicClickFunction

MyDynamicClickFunction(Object sender, EventArgs e).... code

Any way to assign functions to the events of already made controls on a form. Probably during the load event?

Now I have found that there are many ways to replicate Visual Studio's features by accessing User32 and replicating them

Modules & VBA :: Cannot Update Unbound Textbox

Sep 24, 2013

My form has a button that opens another form on which I enter meeting RSVPs. Then that form is exited. I have an unbound text box on the main form that I want to show the total number coming. I have a summation query that totals the number. I have tried everything I can think of to force the text box to requery. I tried putting the dlookup in the textbox itself, then I removed that and tried all of the things below, both in the gotfocus event and the onCurrent event. What else can I do to trigger the recalc?

Private Sub Form_GotFocus()
Me.numcomingtxtbox.Value = DLookup("howmanycoming", "numcoming") & " Coming"
Me.numcomingtxtbox.Requery
Me.Recalc

Modules & VBA :: After Update Event

Jan 14, 2014

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

Modules & VBA :: Unbound Text Box To Update Value Of A Table

Apr 10, 2014

So I have this code in an afterupdate event in an unbound text box to update the value of a table if the textbox is updated:

Code:

Private Sub txtCustRepID_AfterUpdate()
'Go to Calls table and find original value for CustRepID
'Fin the Call ID first
Dim CallIDVar As Long
Dim ContactIDVar As Long
Dim CustRepIDOr As String
CallIDVar = Forms![Contacts]![Call Listing Subform].Form![CallID]

[code]...

This code works well when entering numbers in the text box but it returns error 3061; "Too few parameters. Expected 1" when along with the numbers there is a letter in the textbox.The error happens in this part of the code:

Code:
'Accept change and add new value to table
CurrentDb.Execute _
"UPDATE Calls " & _
"SET CustRepID = " & CustRepIDNew & " " & _
"WHERE CallID = " & CallIDVar, dbFailOnError

The underlying table has text as type of data for this field.

Any Reason Why A Calc'ed Control Doesn't Actually Have An "update" Event?

Jun 23, 2006

If I put a calculated control on my form, I don't seem to have any way of pushing its changes to a field when those changes happen. Access can be downright infuriating at times. I've spent days just putting together a simple invoicing application.

My form is not based on a query like the northwind database, because that created such ridiculous and useless behavior with subforms that I couldn't. So now that it is based on a good old fashioned table, when I change a qty or price, the calculated "extended price" (=[qty]*[price]) field visibly changes just fine, but it never has an "after update" or "after change" event. Why would this be? How am I to save these bloody changes to an actual field in a table without using some grossly inelegant code?

Modules & VBA :: Update Subform To Unbound Textbox Value Change

Aug 4, 2015

As the unbound parent list box record selection is changed, I want the sub form to refresh. Do I put code in the Subform Current Record event?

Master Form Name: frmsr_NewWellEntry
Unbound Listbox - when record selected the primary key populates txtNavWellID (unbound) on parent form

subform Container fsubsrNavSHLBHL Link Master Fields =Forms![frmsr_NewWellEntry].[txtNavWellID]

The read-only form in the subform Record Source is something like: select * from vsrNavigatorSHLBHL where Well_ID =90243..Key The Form used as the subform above will be re-used in multiple parent forms. The parent form data is form SQL Server, the subform from Oracle.

Modules & VBA :: Using Unbound Form Values To Update Table

Jul 16, 2015

I have an unbound form in which a user enters data relating to a credit dispute, and when they hit the Save button I have a sub that is intended to insert that data into a table. This is a bit out of my comfort zone, so I found some code from another forum and adjusted it to my needs. However, I'm getting errors.

The table name is tbl_complaints. The fields from the form are:

txtAcctNumber
txtClient
txtEoscarType
txtEoscarControl
cboMethodReceipt
....

My code is below.

Private Sub cmdSave_Click()
Dim StrSql As String
On Error GoTo ErrorHandler
StrSql = "INSERT INTO tbl_complaints " _
& "(ACCT_NUMBER, CLIENT_NAME, EOSCAR_TYPE, EOSCAR_CONTROL_NUMBER, METHOD_OF_RECEIPT,

[Code] ....

The error I get is error number 3075, and it says I'm missing an operator in the section that references cboResponseType, but I can't seem to figure out what I'm missing. My head is spinning from staring at these parentheses and apostrophes for so long.

Modules & VBA :: ActiveX Control Events Aren't Raised While Calling Its Methods From The Open Event

Oct 9, 2013

We have an ActiveX grid control, 10Tec iGrid, written in VB6. One of its method, Group, used to group rows, raises the AfterAutoGroupRowCreated event so the developer can adjust the look and contents of every group row created during the automatic process of grouping.

When our ActiveX grid is hosted on an MS Access form and we call the Group method while populating the grid in the form's Open event, the AfterAutoGroupRowCreated event isn't triggered. But this event definitely works as expected in other development environments, and even in MS Access if we call Group from the form's Load event.

Is it a well know issue of MS Access, when any events of ActiveX controls aren't triggered while "executing" the Open event

Modules & VBA :: Cancel Parameter In Before Update Event

Jan 7, 2014

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

Modules & VBA :: Form Event To Update Stock?

Nov 14, 2014

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.

Modules & VBA :: How To Bypass Before Update Event When Record Is Deleted

Sep 21, 2014

I have a database which is slowly evolving. Users needed a feature to delete some records without a trail and some with a trail from the form. So I added an apply action field in the subform using which they can delete a record without a trail and if they wanted to keep a trail they could do that too. When user selects "Delete Violations as it was entered in error" the system deletes the record completely which is what everyone wanted.

After six months of use now I am asked to add an audit trail. I managed to do that also. I also looked at Browne's method but my data structure does not match the requirements for that method. I used an alternate method. It works as intended except when a record is completely deleted using the code I mentioned above. Then it goes in the infinite loop. I somehow need to bypass the before update event so that the function to write the audit trail is not called.

I have attached the database ...
