Trapping A Validation Error
Jun 22, 2006
Hi,
I have a VBA code that runs an append query to update a table. Due to relationship integrity a validation error shows (a type does not exist in the connected table): What I want to do is trap the error and write something that the user can understand. Help !
The Code:
Code:Private Sub Report_Deactivate()Dim Msg, Style, Title, Response, MyStringMsg = "Click OK to Import Verified Data to the Invoice Table"Style = vbYesNo + vbMsgSetForegroundTitle = "Verify Import"Response = MsgBox(Msg, Style, Title)If Response = vbYes Then 'This is the problem line DoCmd.OpenQuery "qry_Step_5_appending_invoices", acViewNormal, acEdit DoCmd.OpenQuery "Qry_Step_6_update_fob", acViewNormal, acEditElse MyString = "No"End IfEnd Sub
appreciate any help, thanks

I am using following routine to lift data from Excel files into Access tables. Whole thing works, well, most of the time. The only issue I have is the spreadsheets are received from warehouses and even though they have been given strict instruction to stick to the template, I have had to adjust the spreadsheets. Amongst errors I get are:
Field 'F16' does not exist in table 'SA1'. (In this case I simply delete the last most empty column to fix this).
Or there are column name spellings and in such cases, I get no error and the simply code hangs.
Is there any routine that I could incorporate in the code that clearly states what issues are being experienced. This way I can pass the db to the user to run it themselves.
'Dim dbs As Database, tdf As TableDef
Set dbs = CurrentDb
On Error GoTo Macro1_Err
DoCmd.SetWarnings False
' RunSQL executes a SQL string
[Code] .....

I have the following in the after update event in a Combo bound to a tbl on a Main form;
Sub Combo8_AfterUpdate()
' Find the record that matches the control.
Me.RecordsetClone.FindFirst "[Vendor] = '" & Me![Combo8] & "'"
Me.Bookmark = Me.RecordsetClone.Bookmark
End Sub
The Combo gets its data from a table and I use the Not In List to add data which is not in the Tbl and of course Limit To List is set to Yes.
It works ok with one exception, when data is entered, but not saved, then deleted And the form closed. In this set of circumstances I get an error in the code above. Granted that normally a user will not delete data from the combo then exit the form but it does happen occasionally. I have tried adding On error goto.... but with no luck. Any suggestions?

My table has an auto generated key as a string.
So on the offchance that two clients are trying to autogenerate a key at exactly the same time, I'm trying to trap the 3022 error raised when a duplicate key is entered so that I can repeat the operation with a goto.
I'm raising the error with requery like this:
DoCmd.Save acForm, Me.Name 'next line triggers 3022
DoCmd.Requery
After I realised that the normal handler wouldn't trap it I got the database from this thread:
http://www.access-programmers.co.uk/forums/showthread.php?t=77529&highlight=3022
But it doesn't seem to work for me:

Anyone?

I have a "homemade" switchboard that I am using and the first page allows the choice of administrator or user. I have used access user level security to deny all but administrators access to the administrator "path" in my switchboard.
When a user clicks on it, they get the runtime error 2603 saying that they don't have access. I am trying to modify the on error event so that the error won't show up and a custom message box I create will show up instead, however I cannot seem to get my on error code to do anything. I always get the standard access runtime error return box. Does anyone have any ideas??

I have an "Error trapping" problem.
I am relatively new to VBA and wondered if someone would be so kind and point out the error in my code.
I have a form "frmSelectInvoices" that opens another form, "frmInvoice".
I use the Select Invoices form to select completed jobs that are not invoiced, based on a query.
The user would then select a job that he/she wants to invoice, and "frmInvoice" opens in front of "frmSelectInvoice".
"frmInvoice" is based on "tblInvoices" and a couple of the required fields, (customer, JobID, etc) are filled-in automatically using the information from a couple of fields from "frmSelectInvoice"
"frmInvoice" also has an InvoiceNumber field which tblInvoices needs as it is set as a required field with no duplicates, (this is NOT the primary key).
I am trying to notify the user that the InvoiceNumber has already been used, and to reset the record, so they can enter a new Invoice Number.
The code I have so far is as follows;
Code:Private Sub Notes_Exit(Cancel As Integer)On Error GoTo Err_SameNumber Dim iResponse As Integer iResponse = MsgBox("Do you wish to Print an Invoice", vbYesNo, "SELECT AN OPTION") If iResponse = vbYes Then DoCmd.RunCommand acCmdSaveRecord Forms!frmSelectInvoice!Invoiced.Value = True Forms!frmSelectInvoice.Requery DoCmd.Save acForm, "frmInvoice" DoCmd.OpenReport "rptInvoice", acNormal, "", "[pkInvoiceID]=[Forms]![frmInvoice]![pkInvoiceID]" Me.btnClose.SetFocus Exit Sub End If If iResponse = vbNo Then MsgBox "You can Print it out later from the Invoices Main Menu", , "You Selected NO" End If DoCmd.RunCommand acCmdSaveRecord Forms!frmSelectInvoice!Invoiced.Value = True Forms!frmSelectInvoice.Requery Me.btnClose.SetFocusExit_SameNumber:DoCmd.RunCommand acCmdUndo DoCmd.GoToRecord , , acNewRec Me.fkBookingID.Value = Forms!frmSelectInvoice!pkBookingID.Value Me.fkCustomerID.Value = Forms!frmSelectInvoice!fkCustomerID.ValueMe.InvoiceNumber.SetFocusExit SubErr_SameNumber: MsgBox "Invoice Number has already been used", vbInformation, "Please use a New Invoice Number" Resume Exit_SameNumberEnd Sub
When I test the form with a number I know already exists, or even a number that has not been used before, the error message comes up and it then sets the focus to InvoiceNumber, but when I try and close the form it still keeps coming up and the only way I can get rid of it is to close the application using Windows Task Manager.
Any help on this would be appreciated.
Thanx

Hi guys, I was looking for a way to trap err.number 3314 (when required field is null) before Jet generates its warning. I came across an old post from Rich (below), but I couldn't make it work as yet. In the calling form, under the Form_Error event I wrote the following:
Dim f As Form
Set f = Me
Call fnValidateForm(f)
Could anyone please tell me where my error lays here? I have several forms which have several text and/or combo boxes bound to required fields and I would want to have a generic code, like the one here to trap errors before Jet shows it's Error Message.
Thanks in advance
Regards
Jaime Premy - Belém-Brasil
******************Rich's Function********************
Public Function fnValidateForm(frmA As Form) As Boolean
Dim ctl As Control
Dim Msg, Style, Title, Response, MyString
fnValidateForm = True
For Each ctl In frmA.Controls
'value in the control is required
If InStr(1, ctl.Tag, "Required") > 0 Then
' no value entered or value is null
' or zero for numeric fields
If (IsNull(ctl.Value)) Or (Len(ctl.Value) = 0) Then
ctl.SetFocus
MsgBox "You have not entered all the required fields return to the record and correct this! The record will not be saved if you do not! "
fnValidateForm = False
Exit For
End If
If InStr(1, ctl.Tag, "NumberRequired") > 0 Then
If ctl.Value = 0 Then
ctl.SetFocus
MsgBox "You have not entered all the required fields return to the record and correct this! The record will not be saved if you do not! "
fnValidateForm = False
Exit For
End If
End If
End If
Next
End Function

Ok, I have a delete query that I use to delete records form a table. I have created a form that I run that query from. It has Delete button that runs the query. After I get the message that says "You are about to delete 56 records" and I click No, I get a "run-time error '3059'. Operation Cancel by user"
I did some searching on the forum and thought I could trap this error. But I still continue to get the error at
"DoCmd.OpenQuery stDocName, acNormal, acEdit"
What am I doing wrong and how can I prevent this error from appearing when I click NO or cancel the operation.
Private Sub cmdDelete_Click()
On Error GoTo Err_cmdDelete_Click
Dim stDocName As String
stDocName = "qryDeleteRecords"
DoCmd.OpenQuery stDocName, acNormal, acEdit
Exit_cmdDelete_Click:
Exit Sub
cmdDelete_Error:
Select Case Err.Number
Case 3059
MsgBox "You have canceled the delete operation.", vbOKOnly, "Delete Canceled"
Exit Sub
Case Else
MsgBox "Error number: " & Err.Number & " has occurred. " & Err.Description, vbOKOnly, "Error"
End Select
Err_cmdDelete_Click:
MsgBox Err.Description
Resume Exit_cmdDelete_Click
End Sub

I've made my own record navigation buttons on a form. they work fine, except when i get to the first record. if i click 'previous' then the 2105 error pops up "you can't go to specified record". the buttons were created through the wizard, and have error trapping in them. for some reason, it never actually goes to the error handler. the error message comes up, i press debug, and the 'DoCmd.GoToRecord , , acPrevious' is highlighted.
any ideas why the error trapping isn't working? here's the code:
Private Sub cmdPrevJob_Click()
Dim x As Variant
On Error GoTo Err_cmdPrevJob_Click
DoCmd.GoToRecord , , acPrevious
Exit_cmdPrevJob_Click:
Exit Sub
Err_cmdPrevJob_Click:
If Err.Number = 2105 Then stop
MsgBox Err.Description
Resume Exit_cmdPrevJob_Click
End Sub

I've got my form working, and all of the record updating is working fine, so now I am working on error trapping. I need to check if any of the two textboxes are empty, or nothing has been selected from the combobox. I am using the BeforeUpdate method. I am not getting any syntax errors. I am using an INSERT INTO SQL statement. Thanks.
related DB fields:
SOPNumber (text)
RevisionNumber (text)
TrainingDate (date/time)
Private Sub Form_BeforeUpdate(Cancel As Integer)
If IsNull(Me.cboSOPNumber) Then
Cancel = True
MsgBox "The SOP number is required", vbOKOnly, "Notice"
Me.cboSOPNumber.SetFocus
End If
If IsNull(Me.txtRevisionNumber) Then
Cancel = True
MsgBox "The Revision Number is required", vbOKOnly, "Notice"
Me.txtRevisionNumber.SetFocus
End If
If IsNull(Me.txtTrainingDate) Then
Cancel = True
MsgBox "The training date is required", vbOKOnly, "Notice"
Me.txtTrainingDate.SetFocus

My table was fine and I went in to add a field. I did so and got this error when saving:
"Compile error. in table-level validation expression."
I went thru all my fields and I have no validation rules established. I tried removing the field I added and still have the same error. I used the Compress & Repair function and still have the error. After I go thru the dialogs and exit the table design, I re-enter and the new field is there.

I have code in a BeforeUpdate subroutine of a text box to validate the date. The user can choose to keep or discard the value but the warning only appears if the date is in the future or at least a month old. This is my code:
Private Sub txtDate_BeforeUpdate(Cancel As Integer)
Dim dtCurrent As Date
Dim objResult As VbMsgBoxResult
If (Trim(txtDate) = "" Or IsNull(txtDate)) Then
Exit Sub
End If
objResult = vbYes
dtCurrent = CDate(txtDate)
If (dtCurrent > DateTime.Date) Then
objResult = MsgBox("This date is in the future. Are you sure you wish to leave this value?", vbYesNo, "Warning")
ElseIf (DateDiff("m", dtCurrent, DateTime.Date) > 1) Then
objResult = MsgBox("This date is at least one month old. Are you sure you wish to leave this value?", vbYesNo, "Warning")
End If
If (objResult = vbNo) Then
Cancel = True
End If
End Sub
It works fine when I answer "Yes" but if I hit "No" I get this message: The value in the field or record violates the validation rule for the record or field.
This control doesn't have a validation rule. In fact, there are no validation rules in any of the controls on this form nor on any of the attributes in the control source (table). The date is a required attribute of the table though. I can't hide this extra error message by turning off warnings because it happens after I exit the subroutine, so I wouldn't be able to turn the warnings back on. I also can't trap this error because it occurs after the subroutine ends.
If possible I would want the text box to be cleared and be focused if the user selects "No" to discard the date.

In of my tables called Employee Payroll, I have several earnings fields, and in a previous post I mentioned that I have implemented a validation rule for them which is £2.50 or £2.75 or £3.10. I have also used an error message in Validation Text to help the user if they enter an invalid value.
How can I change this message to reflect what the user types in? For example, if they enter an erroneous value like £9.34, the error message would say, "You have entered an erroneous value" or if they type an extreme value like £3.40 or £0.01, the error message would say, "You have entered an extreme value".
I understand that I would need to state when the data becomes erroneous and when it becomes extreme- so I thought, anything above, £4.00 should be erroneous and any negative values too. Extreme data would be anything between £0.00 and £3.10.
Would I need to use some kind of code in VBA?
Thanks

I use before insert code procedure to insert default value for one, or more fields in row. It is normal to have these fields are disabled. This event occurs when you try to enter a value in any another field in a row. However , when I finish entering the field going to the event before update regardless and trigger a validation of all fields in a row. I am not leaving from row , I want to go further input in other fields.How to insert default (calculated) values in new row.

Error: Error evaluating check constraint in the validation rule
What does this mean?
I have used a combo box in the table to input into 2 fields - one restricted to numbers 1 to 5 and the other restricted to letters A to E
Message comes up when I try to change the view or press submit. Does it have anything to do with the field type?

I've a form in which one of the fields the user enters is supposed to be a unique id. The unique id is an alphanumeric text box.
However, it's possible that another user enters an id that has already been previously used.
I'm thinking that I need to run a Find Duplicates Query with the text box entry and a table that holds all the previously entered ids prior to the form being saved so that I can inform the user of the possible duplication.
My question is are there any ideas on how I can do this or code it?
Thanks

Hi there,
I like having the action query warning appear with what I am doing - "You are about to update xxx rows". The problem that I am having is that when my RunSQL statement in the code executes and selects no to the warning, I get the error -
Run-time Error '2501'
The RunSQL action was canceled.
How can I trap the no selection so that this vba error does not appear?

We are currently developing a simple Point Of Sale Form which consists of 2 text boxes and a list box.We need to trap numeric input from either the keyboard or a barcode scanner at form level,then setfocus on a textbox and enter the input into the textbox.So far have used the keydown event on the form to trap numeric input and setfocus using the following code.
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode >= 48 And KeyCode <= 57 And KeyCode >= 96 And KeyCode <= 105 Then
Me.Input.SetFocus
End If
End Sub
This does not however enter the keyboard or scanner input into the textbox.Is there a method to trap the input,set the focus and enter the input into the textbox once it has recieved the focus.

I am writing a small database using MS Access 2007. I have in it a function for running queries and printing reports. Printing works just fine if any one of the multiple query criteria is give.
I also want to trap errors and present a message if the user clicks the "Print" button without a query criteria. At the moment I only get a run-time syntax error message which has a "debug" button for accessing the entire code. I want a message that will say "There was no search criteria".
This is the code for printing:
Code:
Private Sub cmdPrint_Click()
Dim varWhere As Variant
varWhere = BuildFilter
' Update the record source
Me.RecordSource = "SELECT * FROM q_Vehicles " & varWhere
