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?

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 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

I have a form with an onload event that apparently only runs when it wants to. I've checked the onload property on the form and it is set to event procedure. Went through the code on the event and everything looks good. When i mark it in break mode and step through it it runs fine. When I take the marks off it sometimes works and sometimes doesn't.

I have some tab controls, which for some reason show up white.
I have set their back style to transparent but it doesn't seem to show the grey Windows colour of the background form.
Any ideas why ?
AT the moment I'm having to put grey rectangles in various places to cover this up, which is obviously not ideal.

I have an invoice program that allows users to select a shipping cost option as a toggle in a frame object. When selected "On_Click", the percentage is used to calculate the shipping of the items ordered. Occasionally users will then add additional items, re-click the toggle, but nothing happens. If they click another shipping percentage (there are 3) it calculates. If they click the original percentage now,(essentially CHANGING the frame.value) the calculation occurs fine. It almost seems that the On_Click event toggle in the frame is acting like an On_Change or AfterUpdate.
I have tried the mouse-down event, but this doesn't change the percentage.
I know I could add a separate "Calculate" button after the user makes the shipping selection, but someone is bound to forget to hit it.
Any ideas on how to make the frame On_Click work if the value doesn't change in doing so?

I have a Combobox so the enduser can search and select items for the form below it rather than clicking the arrows for Next/Previous.However I have an issue with DLookup queries.My Combobox is called 'F_ComboBox' (I use F_ in my forms to indicate it's a form textfield and not from a table).My first field in the form, called 'F_ProdID', I want it to select the rows ID from the Combobox option selected. So it's simply:=[F_ComboBox]Which works fine, it shows the ID for what I selected... but when I do this to show my ProductName...=DLookup([ProductName], 'Products', [ProdID] = [F_ComboBox])Or the same but using the first textfield:=DLookup([ProductName], 'Products', [ProdID] = [F_ProdID])It loads once but if I select another item out of the Combobox it doesn't change, it just stays on the last result. So the query works, just doesn't refresh when a new item is picked from the ComboBox.Am I doing something wrong?Thanks,Nick.

I have a combo box on a form with claim #s. When selecting a claim # the appropriate record displays, but when using the record selector to advance to the next record, the combo selection does not update.

Upon closing my frmInventory the amount stock of stock is checked against a minimal stock value. If the stock amount is below a set minimal value a subsequent form is opened telling you that stock is low and an email message is generated to notify a manager. I have a checkbox on that form which is set to "True" upon close using an update query. The checkbox is there to give users the option to either send or not send a reminder message that stock is low when a message has already been sent earlier.
The problem is that using that update query ALL records are set to "sent=true" and not just the 1 record I intend.
This is my code in the "on close" event:
DoCmd.OpenQuery "qryUpdateEmailMinimal_True
and here's the SQL:
UPDATE tblInventory SET tblInventory.emailSentMinimal = True;
I assume what is missing is a reference to an inventoryID number. How do I do that?

Right now, I'm working with an SQL code of
Code:
"UPDATE Individuals SET [ShareholderOf] = " & Me.CompanyNo & " WHERE [Name] = '" & PerName & "';"
However, doing so will obviously change the "Shareholder of" field into what the user inputs (Me.CompanyNo). What should I use if I want it to ADD the user input rather than REPLACING the old [shareholderof] value?

Hi Guys
I want to ask you that what are the main reason that Microsoft Access is not using in large companies. I want to ask you that "Is that true that M-access can,t bear the too much records in one database and it slows down.My friend ask me that if we use backend of sql server and front end of Microsoft Access then what will happen? Is there any chance to increase the performance of Access based software by this method

Please refer to the attached file. The form of concern is frmAssessmentInput.
Select the appropriate criteria per instructions (in red), including entries on the continuous subform. Then click the "Input data" command button. A 2nd form opens (frmObservations) that contains a textbox labeled DocumentStreamID, and this textbox SHOULD contain the value from the corresponding DocumentStreamID textbox contained in the master form, where you clicked the command button. However, even though the sources are linked properly, the value doesn't pass if you click the command button immediately after adding a new record to the continuous form; it only passes if 1) the master form is closed and reopened first, or 2) if you close the 2nd form, toggle to design view and back to form view for the master form, and then click the "Input data" button again.
What is going on here? Given that the value passes once another procedure is run, do you think this a requery problem? I tried placing a VBA control requery in the 2nd form's On Current and On Load events, but this didn't solve things for me so I took out those event procedures (code could have been wrong though).

I'm running into an issue with my forms. I have a form that contains a subform, that contains a list of projects. This list is read-only. To update a record, you can double click on it, which opens another form filtered on this record, and which contains the fields in the first form as well as some others.
I have a command button on that last form to "Save and close", which fires up a macro that saves the record and closes the window.
Now, the issue that I'm having is that, when the window closes and I'm once again in front of the first form with the list of projects, the values of the record I changed are not updated and when I click on another record, Access tells me there's a conflict in the values and asks me if I want to keep the changes, discard them or copy to the clipboard.
It seems to consider the old values from the first form as a change, and thus asks me which to keep between these, and the actual (proper) changes I made in the dedicated form.
For the proper changes to be applied, I need to select "Drop changes".
I tried to requery the first form, also undo the changes to it after closing the window, but none of that worked.
I'm actually basing this on one of the templates, which does exactly what I want and which obviously works...

Hi All,
I created an Event Procedure on the After Update event for a control in a continuous form. Basically, if certain conditions are met, I want it to disable another control. It works perfectly, except it is disabling the controls for all the records instead of just that record.
Does anyone know how to get it to just update that record? I've been researching and cannot figure it out!
Thanks in advance for any and all help :)

I am dynamically trying to set a control default value. I have the code below in the On Load event of the form. I get an error msg that says "Run-time error '2467': The expression you entered refers to an object that is closed or doesn't exist."
Forms(mainform)("Dyn_" & Trim(str(Project_ID)) & "_SubFrmTab03" & PT_Suffix & "_Approval").Controls("Groupid").DefaultValue = "=Forms!" & mainform & ".ClaimInfoGroupID"

I'm having a weird problem in VBA on a button click. For no apparent reason the database closes itself. No error, no crash - it just closes. I've compacted and repaired it, recompiled it, but still exactly the same. The strange thing is, if I insert a blank message box at the point in the code where it quits, everything then works perfectly!
Also, if you leave Text4 empty so that it displays the message box telling you to enter a code to start, when you then enter something the next time it also works perfectly. Somehow the process of displaying the message box seems to fix whatever the problem is. I've tried pausing the code at that point, I've tried changing the focus to a different control or another form.
Here's the code:
Private Sub cmdReqLookup_Click()
Dim strTaleoReq As String
Dim strTaleoID As String
Dim intIDMatches As Integer
Dim strContractID As String
[Code] .....
'This is where the database quits. If I add a message box here, it then runs perfectly!
'Disable button
Me.cmdReqLookup.Caption = "Please wait..."
Me.cmdReqLookup.ForeColor = vbRed
Me.cmdReqLookup.Enabled = False
Me.Refresh
ScriptHold (1)
[Code] ....

Was trying to append an Excel 97-2003 spreadsheet to an existing Access 2010 database.
The last field in the spreadsheet is Date Update.
When I click 'Finish' I get the error "Field Date Update doesn't exist in destination table <name of table>.
This database was created in Access 2003, and was not updated since and I don't have Access 2003 on my destop.
I saved the Excel Spread as a Excel Workbook *.xlsx and tried to append it. Same Error was the result.

I am using an active x control that when you right click on it, it automatically pops up an "About" box showing information about the control. I wouldn't object to this, but I need to use the right mouse down event for another purpose in my program. So far I have discovered that the code I put in the the event works, but only after the "About" box pops up. Is there anyway to cancel or prevent the popup? The reason that I need the right mouse down event is because is that I am already using the left mouse double click event, and I can't use the left mouse down event because then it always fires before the left mouse double click event. This control doesn't have any single click events. Ideas?

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

I have validation on a checkbox on a sub form and after the validation fails and the cancel = true is executed in the before update event, I am unable to select the checkbox on the form. Access will not allow the selection. my subform is called frmContactType so hopefully I am referencing it correctly:
Me.frmContactType.Form.chkAssociate

Hi, i have a query which looks at a table named "attendance" the query includes the fields: "employee number", "absent code" (a 3 letter code), "absent reason" (list of different reasons) "shiftdate" (weekly shift dates in format: DD/MM/YYYY). If possible i would like to be able to promt the user to enter a employee number, then a absent reason (ideally from a list box) and show all occurences (with all the shiftdates) only of that particular absent reason within the last 12 months, and ideally calculates in another field the number of times that employee has been absent for that particular reason for the last 12 months.
Does this make sence?, i know how to promt the user to enter a employee number but not sure how to go about the rest, any help with what seems to be quite a challenging task to me would be excellent.
