Modules & VBA :: Error Trapping For Data Validation
Feb 15, 2015
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] .....

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 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

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 have 2 combo boxes on a form. The 2nd box is not visible unless the 1st box is set to a specific value (Illness). Once the specific value is set, the 2nd box appears with appropriate data for selection.
Goal #1:
I would like to have the form checked before it is closed to ensure that if the condition in box 1 is "Illness" then the 2nd box must have a value and can not be null.
Goal #2:
I am also having problems with the 2nd combo being visible when form opens or becomes current. The field is set to visible=false normally but needs to be visible when form opens if the conditions mentioned above are meet (true).
Private Sub Form_Unload()
If IsNull(Me.Incident_Classification) Then
MsgBox "Please select a type of Illness"
Me.Incident_Classification.SetFocus

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.

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 am using below code to import various Excel spreadsheets into Access. However every now and again below code goes into error, usually because there is no "toimport" range in the Excel file.
So I would like to use On Resume Next, so it can import all other files. But in order to do it, I need also to be able to somehow capture information about all files that went into error, so I can fix them.
I would like to create like an "error log" and I would like Access to update it with information about all the files that were not uploaded + error message + date/time.
Ideally I would like it to be in Excel file. I tried to use DoCmd.TransferSpreadsheet but it does not do what I need
Code:
Function import()
Dim strFile As String
DoCmd.SetWarnings False
' Set file directory for files to be imported
strPath = "C: est"

I have a search query that searches for different results based on 3 criterior. I have set up a form so that the user can input the text into the form and then once the Submit button (that i created) is clicked the query table will be shown.
My question is:
Is it possible to have an error message box appear when i click submit and no data is returned by the search query?
I'm hoping for the message box to say "No corresponding records to your search criteria. Do you want to try again?"
Then the options given in the message box are Yes (where they should be taken back to the search form) and No (Where they are taken to another form).

The database emails personnel, that I enter into each record, at 15 and 30 days prior to expiration using SendObject.the database emails personnel, that I enter into each record, at 15 and 30 days prior to expiration using SendObject. I have a total of three fields where I enter an email address for each record; Email, E2, and E3. If I enter data in Email and E2 an email is sent. If I enter data in Email,E2, and E3 an email is sent. The problem happens when I only enter data in Email, I get an error 2295. I'm sure that it has something to do with the below piece of code and my use of Nz:

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.

I have vba code that creates the following SQL:
SELECT SubscheduleID, EventID, WeekOrder, DayID, StartTime, EndTime, Priority, CanJoin, PatientTitle, PatientNickname, IncludesPatient, IncludesAftercare, Letter1
FROM [qryScheduleCombinedDetails]
WHERE (SubscheduleID = 1 AND IncludesPatient = -1 AND DuringAftercare <> "AC only" AND (WeekOrder = "All" OR WeekOrder = 3 OR (WeekOrder = 1 AND Letter1 = "XYZ")) AND DayID = 2 AND StartTime <= #8:00:00 AM# AND EndTime >= #8:30:00 AM#);
When I try to run it, I get a "data type mismatch" error. When I put the same code into a query, I get the same error. However, it will run if I delete either condition from within the (WeekOrder = 1 AND Letter1 = "XYZ") pairing. I can't figure why it can run with either of those, but not both together.
WeekOrder is defined as String. Letter1 is calculated as Cstr(Nz(IIf(Letter,"XYZ","ABC"))) within [qryScheduleCombinedDetails], because I wanted to make sure that it would be recognized as a string.
