Dumb Question Of The Week - Error Handling
Apr 26, 2007Do you folks include error handling in every single procedure?
Even on a "Quit" button with DoCmd.Quit behind it's OnClick event?

Error Handling
Nov 23, 2006I have recently upsized an Access database to SQL Server. The .adp is for the most part working fine.
However, when an end user tries to create a duplicate record in one of the Primary key columns of a Form he gets a SQL Server error message as follows:
"Violation of Primary Key constraint. Cannot insert duplicate key in object myTable".
This is obviously not a very useful error message. What would be the best way to ensure that a more useful error message is returned?
I have considered adding code to the "After_Update" event of the cell in question. This however seems long winded. Is there an easier option?
Thanks

Error Handling
May 12, 2005Hi all
The following code only half works. I want to stop an ugly error occuring when primary keys are duplicated. In the following code the error handler picks up and displays a simple message when a user attempts to add duplicate values. BUT if the users adds a record, the record is successfully added followed with the same error message. I think I've put the error handler in the wrong place, but I can't figure out where it should go. Any ideas are much appreciated.

Error Handling - Enough To Put In On Error Event
Sep 24, 2005Every form has an on error property.
Is it enough for error handling to code the on error property for each form?
With enough I mean error handling which lets you resume the program.
Ontherwise I have to code (or call a procedure) for each coded event which i wouldn't prefer
For instance now I'm putting error handling in each event but would consider it more efficient if it can be placed once in each form
Private Sub cmdReport_Click()
On Error GoTo Err_cmdReport_Click
Dim stDocName As String
stDocName = "rptOfme"
DoCmd.OpenReport stDocName, acPreview
Exit_cmdReport_Click:
Exit Sub
Err_cmdReport_Click:
MsgBox Err.Description
Resume Exit_cmdReport_Click
End Sub
Error Handling With Macro
Apr 30, 2006I currently have a macro that sets the value of several fields on a "lost focus " event; however there is an error that I would like access to ignore, is there any way to have this macro process this function "On Error Resume Next" ?

On Error 2427 Handling
Mar 2, 2005I have a form where the user enters a year then clicks on a command button to open a report.
If a year that there is no data for is entered an error 2427 occurs.
I have tried putting the following code in the on error event of the form with now success:
Select Case DataErr
Case 2427
MsgBox "There are no records for the year you entered" & Chr(13) & "Make sure you entered the correct year”
Response = acDataErrContinue
Case Else
Response = acDataErrDisplay
End Select
Does anyone know how to trap this error?
Thanks
Error Handling Problem
Aug 8, 2006On a form i have a textbox to enter a date and multiple command buttons to open other forms.
After entering a date value, followed by either a tab or clicking on one of the command buttons, i want to validate the entered date value. If the date is invalid i want to display an error message and the cursor positioned on the textbox field.
The LostFocus event of the textbox is as follows:
Private Sub txtDateField_LostFocus()
If Not IsDate(txtDateField.Value) Then
MsgBox "Date invalid."
txtDateField.SetFocus
End If
End Sub
If entering an invalid date is followed by a tab, the error is displayed but the cursor is not positioned on the textbox field.
If entering an invalid date is followed by clicking on one of the command buttons, the error is displayed but the expected form is opened.
How to position the cursor appropriate and how to prevent opening the form?
Who helps?

Error-Handling Help Needed
Oct 25, 2006How do you do an Access/VBE split screen? I want to be able to watch the code execute as I enter data into the form.
I have redesigned a database, essentially building a new one from scratch. I have all of the forms created and they are working beautifully. :) Now, I'm error-handling to create user-friendly messages. I have a superb Access programming book, but it only briefly mentions error handling and doesn't describe at all how to do it. Most of my forms are pretty simple, and I've been able to complete all of the error-handling tasks using the Form Error event as well as coding other events with the error message number. However, the main form is complex and includes a function in a standard code module and a custom sub routine.
TIA!

Error Handling When Report Cancelled
Oct 12, 2007Just a quick one.
I'm not usre how to handle the error when cancelling a report. so when I hit a control to bring up a report and say I cancel it before I put in any parameters for example I get the dialog box " runtime error" "OpenReport action was cancelled" etc.
Could anyone help me on how to handle this with VBA so that it's at least a more user friendly dialog box?
thanks
Modules & VBA :: Error Handling With Loop
Aug 6, 2015I've got a problem with a loop for producing worksheets (reports). When everything works there's no problem but when one of the reports namely rptChemoOralWorksheet doesn't have data available to produce the report the loop finishes and then all remaining worksheets don't print.I've put in a standard error handler with MsgBox, but it's never triggered. I've also tried
Code:
On Error Resume Next
but again rather than skip the DoCmd.OpenReport "rptChemoOralWorksheet" (when the error is present) and move to the next one to continue printing through the list the loop stops and the subsequent code starts to run.
Code:
Dim mydatabase As DAO.Database
Dim rst As DAO.Recordset
Set mydatabase = CurrentDb
Set rst = mydatabase.OpenRecordset("atblChemoWSLoop", dbOpenDynaset)
Dim rsBN As String
Dim rsDose As Double

General :: Error Handling Query
Aug 28, 2012I'm trying to split out the first name from a GivenNames field which contains first and middle names. Some values in the GivenNames field have just a first name. I've tried the below formula, but still get some #Error responses where only a first name exists in the field.
My formula:
Given Name: IIf(IsError(Left([GivenNames],InStr([GivenNames]," ")-1)),[GivenNames],Left([GivenNames],InStr([GivenNames]," ")-1))
Error Handling For ODBC Linked Tables
Jan 17, 2006My tables are sybase linked tables to my Access front end. I get this error whenever i click away from my mainform while my not-null fields (textboxes) have not been entered. So, i would like to put an error message "somewhere" that tells the user to fill in the necessary fields and highlight the necessary textboxes in red, instead of this scary ODBC message
http://img82.imageshack.us/img82/6829/error0el.png :eek: :eek:
When i put my error handling in the afterUpdate or afterInsert Event. I still get the above error msg instead of my msgbox.
Where do i put this message? or should be question be, "what the proper way to handle this intimidating error? :)
Here's my error handling:
On Error GoTo Err_Form_AfterInsert
'do something
Exit_Form_AfterInsert:
Exit Sub
Err_Form_AfterInsert:
MsgBox Err.Description, vbExclamation, "Please enter the Project Name, Project Leader Initials, Main User and Status Code" & Err.Number
Me!Combo67.BackColor = "red"
Me!Combo65.BackColor = "red"
Me![Project Name].BackColor = "red"
Me![Project Leader Initials Combo].BackColor = "red"
Resume Exit_Form_AfterInsert
Thanks in advance for your help :D
Error Handling When LostFocus Doesn't Work
Jun 7, 2006Hi, hope somebody can help with this problem.
I have a med-large db shared on network. Am under some pressure to split front/back so more people can do data entry, but want the forms to be semi-finished before putting them on everybody's c:drive.
The problem is error handling for required fields. Some fields are required in the underlying tables because if users don't fill them in, reports are useless. But Access error msg for required fields are too strange, users just close down, maybe wrecking the thing. Don't want to eliminate Close button yet in case they get stuck in Access hell.
I got one ( !! ) field locked in well using LostFocus event, but what do you do if users just mouse into fields at random? LostFocus won't work if it never had focus, right?
(Would much prefer to just use unbound form and give choice of "Field is required" and "OK" or "Cancel this record" but realize that's asking for a lot of help here.)
Any assistance you can offer would be MUCH appreciated!! Vba course isn't until July.
Thanks,
Modules & VBA :: Error Handling (label Not Defined)
Jan 12, 2014I am studying error handling. I am using VBA Developers Hand Book and some Google stuff. I have been over the material several times and cannot find my mistake. When I click cmdFindState it give me "compile error" " label not defined",and stops at:
Code:
"On Error GoTo Err_cmdFindState_Click"
Code:
Private Sub cmdFindState_Click()
On Error GoTo Err_cmdFindState_Click

Queries :: Error Handling In A Query That Was Run From A Macro
Aug 19, 2013(I'm not sure if this belongs in the macro or query forum)
I have a macro that opens 15 queries and ends with opening a report.
The final query asks the user to type in beginning date, then an end date. Now when there's a data mismatch (i.e., he spells feburary), the macro halts. No harm no foul, they can just click the command button again, but I'd rather not.
What I'd like to do is place a msgbox (i.e., "Check Your Spelling") and then reroute them back to the query.
Modules & VBA :: Error Handling / Loop / External Paths
Aug 14, 2014I am setting up a form to send multiple attachments to an email.I have a query "qry_DwgEmail" that has an ID and a path column. On the form I have a button with the code below in the Click Event.The code below all works fine unless the path is incorrect, so I would like some error handling to be able to either:
1) Stop the code from running and display a message box with my message.
2) Continue the loop and then have the message box display what files could not be found (Preferred).
Note, the following code was taken from one of the forums I am not 100% on what it all means.
Code:
Private Sub btn_CreateEmail_Click()
Dim MyDB As Database
Dim MyRS As Recordset
Dim objOutlook As Outlook.Application
Dim objOutlookMsg As Outlook.MailItem
Dim objOutlookAttach As Outlook.Attachment
Dim TheAttachment As String

Poor Error Handling In Access - It's Like Going Back In Time. Anyone Agree?
Sep 22, 2005I'm sick of the lame excuse for error messages that Access gives out.. I'm talking about 'Overflow', 'invalid use of Null' and such like.
What about telling you what field/expression caused the error and on what record if applicable.
It's so frustrating - Access obviously knows what caused the error but refuses to tell you so you have to go through the annoying process of taking out fields one by one (when in query view).
Does anyone agree that they need to make the error handling in Access much better?
Thanks for any interest in my post.
Modules & VBA :: Running Multiple Queries In A Routine - Error Handling
Oct 9, 2013I am using access 2010. I use basic error handling in my routines:
Code:
On Error GoTo errHandler ... exitHere: ... errHandler: MsgBox "Error " & Err.Number & ": " & Err.Description
The problem is lately; while testing I am running multiple queries in a routine. When it fails; its hard to identify which query has the problem. So I hit control break; debug and try to find it. After I fix it; I debug and reset; i get this continuing hourglass thing in the form of a spinning circle until I close and reopen the database. I think I need better error handling but not something really complicated because I need to put it in quite a few routines throughout the database.
General :: Handling Error Database Engine Cannot Find Record
Jul 8, 2013 how to deal with errors specifically with error "The Microsoft Access database engine cannot find a record in table".Database which I'm creating have table Products, which contains information about products. Most important information in this table is if product is VATable or not. I decided to define product names in invoice table that database can recognize products and calculate VAT in invoices if product is VATable. Problem starts if you have new product. When I add new product in invoice it counts VAT but when i go to next record I receive message mentioned above. It doesn't allows me to go to next record or save record.
I was wondering is it possible to make it that access allows to fill invoice, informs about new products only when i have finished adding all products in invoice and than gives opportunity to add them to product list?
Dumb Question.....
Jun 15, 2006Ok, I've spent about 3 hours building my table, and now want to actually use it ;). I think I can do everything except this one thing. Which I could probably write a whole bunch of unneeded VB code to do it, but hopefully you guys can provide a better answer.
Ok, my table has 326 records. Each record has a field with a dos command in it. So 326 dos commands total. In my form, I want to create a command button that will launch the dos command I have listed in the field of the current record.
i.e. record 1: blahblah1.exe, record 2: blahblah2.exe. If I'm viewing record 1, I want to launch blahblah1.exe, record 2, blahblah2.exe so on and so forth.
There's probably an extremely easy way to do this, but I don't use access much and have never really learned. Any help would be greatly appreciated. :)

A Dumb Question
Aug 21, 2007Every time I use the build tool in a query my quotes do not display correctly so my formulas do not work. When I type a quote it appears slanted like italics. It is an inconvenience. Anyone seen this before?
thanks

View 2 Replies View RelatedProblem With "on Error" Handling
Mar 29, 2006In Microsoft Access 2002 I have a routine to add or edit an entry in a table. Because it is a multi user environment, there is a possibility, that someone else is currently editing the very same entry of the same table. Therefore I do an error handling with a message box appearing in case of an error to tell the user that this entry is currently locked. The user then has the choice of "cancel" or "retry". There is no problem with cancel, but if retry is selected, I repeat to edit the entry once more. Now, if the entry still is locked, I do not end of in the error routine again, and I get a runtime-error with the "update" command and exit the routine. It looks like the "on error goto Write_Err" command is ignored in the second go. Can anyone tell me what I did wrong? Here is the code I'm using:
Set ds = db.OpenRecordset("T_TeilResultate", dbOpenDynaset)
Temp = "((Fehlernummer = 1) AND (Resultat = " & ResultatID & "))"
ds.FindFirst (Temp)
If ds.NoMatch Then
ds.AddNew
ds!Resultat = ResultatID
ds!Status = 2 '2 entspricht FAIL'
ds!Fehlernummer = FLogID
ds.Update
ds.Bookmark = ds.LastModified
Else
'Es existiert ein Teilresultat mit Fehlerlog 1 das editiert wird'
Do
Writeok = False
'Form_F_NeueTeilresultate.RecordLocks = 2
ds.LockEdits = False
ds.Edit
ds!Status = 2
ds!Fehlernummer = FLogID
On Error GoTo Write_Err
'here is the problem if the loop runs twice!'
ds.Update
ds.Bookmark = ds.LastModified
ok = True
Writeok = True
Write_Err:
If Writeok = False Then
ds.CancelUpdate
Antwort = MsgBox("Table is currently locked!", vbRetryCancel)
If Antwort = vbCancel Then Writeok = True
ok = False
End If
Loop Until Writeok
End If
Thanks for any advice.

Reports :: Inserting Page Break To Show Week By Week Pages
Feb 11, 2015I've created a report based on a query that shows me the jobs that have been added to tblJobs between two selected dates.
The report works fine and displays all the information I need, however other than being sorted by day of the week i.e. Monday, Tuesday, Wednesday etc. The records just run on one after another.
I want to create a page break, so that a full week is shown on a single page before then forcing a new page when it moves in to the next week.
Week Commencing Day From Week Number
Nov 6, 2006I have a query that groups records by date into week numbers using the following expression.
WeekNumber: DatePart("ww",[Date],2)
I would prefer to display the result as the week commencing Monday date.
How?
