I have a Composite Index to prevent duplicates I get the error message. How can I trap this?
I resolved it with this PHP Code:
'Trap Error.
Dim DataErr As Integer
Dim Response As Integer
Dim Message As String
If DataErr = 3022 Then 'Duplicate value entered
Response = acDataErrContinue
End IfÂ
I'm in Access 2013 and I built a form with multiple drop downs. Here is what I have in the same order of which the user must choose from......
Document "Field Observation", "Monthly Inspection", "Safety Roster" (The user must first choose the document from this drop down he is recording)
Supervisor "First & Last Name" (The user then chooses the first & last name of the specific Supervisor name he is recording the document for from this drop down)
Manager - This field automatically populates based on Supervisor.
AOR - This field automatically populates based on Supervisor.
Org Unit - This field automatically populates based on Supervisor.
Month "January", "February", etc. (The user then chooses the Month of which the document will need to be applied to)
I would like the form to trigger an error with "This document is already recorded for this month" when the user chooses "Monthly Inspection" OR "Safety Roster" for a specific "Supervisor" for a specific "Month" that is already recorded in "TBL_DataTracker". The TBL_DataTracker is where all of my records are stored.
Can anyone tell me why access puts the primary key field in the index list twice for the same table? For example i have a primary key called CustID, when i go into design view and click on the index button on the toolbar, i see it listed twice, once as primary key and then again as its own field?!
I dont see the reason for this but often times with many of my databases i see this happen to many of my tables. :confused:
I'm using Pat Hartman's code to select items from a list box and then append the records to a table. If a user doesn't select anything before clicking the buttom I'm trying to give them an error message. I've tried it in various places but can't get it to work. The attached is giving me the error message regardless of whether they have selected anything or not.

Any suggestions?

If you open the attached sample you will see what my problem is.
I have Form /Subform with look up combo that will not allow duplicate entries in same subform record. This works fine, access displays an error when a duplicate has been added as it should. What I want to do is trap that error myself and display a msgbox that will allow the entry to undo (the msgbox undo etc I can handle, it the trapping of the error)
Thanks in advance.
I am using Access 2010 32-bit on a Windows 7 64-bit platform.I have a database that I have imported existing data into. For the most part, I have eliminated duplicate entries in my Item Number field.
Obviously I have missed at least one (or possibly more) duplicates. When I try to create a NO DUPLICATES index, I am informed that there are duplicate entries.I am looking for a quick way to generate a list of values that are duplicated so I can address those and correct them.Item number field is a number field of type DOUBLE with 2 decimal places.
I have a form with 22 data fields.
There are 4 entry flow paths.
(1) is 1 to 9, 10, 20 to 22
(2) is 1 to 9, 11 to 14, 20 to 22
(3) is 1 to 9, 15 to 17, 20 to 22
(4) is 1 to 9, 15 to 17, and stop at 19.
If information is in Field 10, then I need to prohibit entry in the other 3 paths.
How can I do this?
Hi,
I have created a database that monitors containers that are being hired. When a container is hired some details are entered and remains the same until we receive an invoice to state that the hire has stopped. Subsequently, the database is updated and an invoice sent. The container is then hired out again and some details are entered on the database and so on.
There are two check boxes to state whether the container hire has been completed and whether the client has been invoiced.
I am attempting to stop duplicate entries of container numbers being entered onto the database when the transactions are not complete and the client has not been invoiced.
I cannot use a primary key because the containers are reused and hence the container number will be on the field more than once. I have also tried a find duplicates query, but this found duplicates in the whole table and returned only the duplicates that were in the criteria I had specified.
Basically, I want the validation or whatever to prevent duplicates only when the two check boxes are 0.
Thanks in anticipation for your help.
All the best,
Roly
Help! I'm on of those home grown programmers. I have the report all ready to go. Four columns with data from a table. The 4th column is showing duplicates that I would prefer just show up as blanks. Following the 'help' screen I changed the preferences for that box to HIDE DUPLICATES: YES. The help screen says this should work exactly as I hoped, but when I run the report every field is populated.
Any ideas??? I'm sure there is some small config change but It is beyond me.
Thanks,

I have a form with a text box called txtID. When the user types a value in the text box I want it to check if the value already exists in the field ID in table "Headcount" (a linked table from SharePoint). If it does, then I want a pop up box to display with error. Is this a Dlookup function?
I've tried DCount but can't get that to work.
Hi, this a great forum and i'm asking for help :)
1.i trapped error 3314 and other errors at my custm buttons(save,edit...) but...
at my 2 forms(one single and the other continuous, access gives me an error about an empty field in a table (primary id), when i press tab (it moves to next record).
The same action has my continuous form when i click at an empty field at next record or pressing tab with empty values at primary fields.
What can i do to post my own messages?
2. I have a text box (a) that takes value form an other text box (b): b=2*a. both text boxes send values to a table
How can i prevent user from chanching the value on (b) text box?
thanks in advance

I would like to trap event name where an error has taken place in.
I do not want to type in every event name by hand for each error messge.
Exit_Command27_Click:
Exit Sub
Err_Command27_Click:
Call ErrorLog(Me.Name, EventName, Err, Err.description)
Resume Exit_Command27_Click
How do I programmatically force an error dialog to make a certain choice?
I'm able to trap the dialog via the following code:
Private Sub Form_Error(DataErr As Integer, Response As Integer)
If DataErr = 7787 Then 'record updated by another "user" (subform)
MsgBox "Error trapped!"
Response = acDataErrContinue
Else
Response = acDataErrDisplay
End If
End Sub
Problem is, if I bypass the 7787 error in this manner, it defaults to dropping the changes, rather than saving the record, which is what I want. (Both are choices on the dialog.)
Any help would be most appreciated.
i am using access against an Oracle DB through an ODBC driver, and when appending records to a local table, if access gets an Oracle record error "#deleted", the append query aborts. . . that's fine, but I can't figure out how to trap the error to get the rest of the records. . .
ugh! see attached graphic
thanks

Hi, I have a button in a form that loads a report, if there is no data in the report then 2 error messages are displayed, however as these messages have no affect and they do no harm as such I would like to prevent them from being displayed. The error messages are error 91 “invalid use of isnull” error and error 2501 “cancel event error message”
I’ve been able to prevent either error 91 from being displayed or alternatively 2501 using a single if statement but not both of them together using two if statements.
(If error 94 is displayed, I would still like the report to open, error 2501 is displayed after the report is closed if there’s no data & i just want this message not to be shown)
Any ideas what im doing wrong? :confused: any help much appreciated
Regards
Kevin
Below code works ok (to trap just the one error message):
Err_cmdPreview_Click:
If Err.Number = 2501 Then ' ignore cancel event error
Else
MsgBox Err.Number & " - " & Err.Description
End If
Resume Exit_cmdPreview_Click
End Sub
But the below code here doesn’t work (when I use 2 if statements to try & trap both of the error messages)
Err_cmdPreview_Click:
If Err.Number = 94 Then ' ignore isnull error
DoCmd.OpenReport stDocName, acNormal
Else
If Err.Number = 2501 Then ' ignore cancel event error
Else
MsgBox Err.Number & " - " & Err.Description
End If
Resume Exit_cmdPreview_Click
End Sub
Attached is my many to many relationship setup. I would like to prevent the possibility of entering the same person more than once for the same training event. I am assuming that I do this by setting an index setting for a field the junction table?
View 3 Replies View RelatedI am importing .txt files into Access table via VBA code (i.e., not via Saved Import Spec). Is there a way to trap the error if a particular field does not get imported due to incorrect format? When you import via Saved Import Spec and there are errors in formatting, Access generates an 'ImportErrors' table, which tells you which fields could not be updated.
Is there a way to generate a similar 'ImportErrors' table with VBA error checking?
I have a client database that has recently had multiple duplicate entries. I need to reduce or negate this erroneous activity. I have a client table where I record amongst others, the following;
key
[christian_name]
[family_name]
[dob]
......
I believe that to prevent duplicate entrie via form I have created an additional field called "unique" given it as a unique index which I want to have populated with the joined fields first_name & last_name & dob (IE johndoe01/01/90), and then as user enters a new client it wont allow a duplicate.
However I need to fill all the existing customers (3600+) with the relevant joined existing data. If I create an expression I can cajoin the fields in a select query but when I try to make an update query the same syntax comes up with empty fields.
select query sql that worked to show field ...
SELECT divers.christian_name, divers.family_name, divers.dob, [christian_name] & [family_name] & [dob] AS Expr1
FROM divers;
update query that was empty ..
UPDATE divers SET divers.[unique] = [christian_name] & [family_name] & [dob];

I created a subforum with an updateable query, and this works. I can view the results of the query, modify them and add new records.
However I shortly realized that once I deleted a record (either by some VBA code, or by SQL) that I could not re-add the same record through the subform.
I've made sure that the record is deleted, so there is no duplication of the key.
I've made sure that Index is Duplicates OK, so there is no duplication issues there.
What am I missing?
I'm trying to record a payment, but I keep getting this error upon completion of my form:
Index or primary key cannot contain a null value.
I've checked the data types and relationships and they seem to be fine.
Here are links to my Access files (2007 & 2003)for your reference:
[URL]
I want the recordnumber displayed on a continuous form. The code below works with the command button, but not afterinsert.
Here's the code: (function GetPosition() is the control source)
Private Sub Command28_Click()
numbers
End Sub
Private Sub Form_AfterInsert()
numbers
End Sub
Private Function getPosition() As String
If Me.RecordsetClone.RecordCount > counter Then
counter = counter + 1
getPosition = "#" & counter
Else
getPosition = "#new"
End If
End Function
Private Sub numbers()
counter = 0
Me.Requery
End Sub
So it should do something like this:
#1 [ctrl 1]
#2 [ctrl 1]
#3 [ctrl 1]
#new [ctrl 1]
But called from after insert only the records on the screen get updated unless I scroll up, so simplified it looks like this:
----------------- top of subform after scrolling up
#3 [ctrl 1]
----------------- top of subform before scrolling up
#1 [ctrl 1]
#2 [ctrl 1]
#new [ctrl 1]
Where else can I put it or how can I modify the code to make it work?

Using an Access 2003 format database, opening in Access 2007...When I try to open my database I get two errors and it will not open.ID is not an index in this table.ParentId is not an index in this table.
I get the error when it opens with autoexec and when I bypass autoexec. I have a master copy of the database that I tried to link to the first database to import tables but I still get the error.
I was using the following code on a field (ItemCode) that was indexed to prevent duplication of records. The intent is that the user will get an error message that a duplicate exists before they enter all the data for the record and get the built in error message that Access 2003 provides when an index violation has occurred.
Code:
Private Sub ItemCode_BeforeUpdate(Cancel As Integer)
Dim Answer As Variant
Answer = DLookup("[ItemCode]", "tblQuestions", "[ItemCode] = '" & Me.ItemCode & "'")
If Not IsNull(Answer) Then
MsgBox "Item Code already exists" & vbCrLf & "Please enter unique Item Code.", vbCritical + vbOKOnly + vbDefaultButton1, "Duplicate"
Cancel = True
Me.ItemCode.Undo
Else:
End If
End Sub
Now, the index for this is based on two fields (ItemCode and Question Group). I would like to display the same message before update but don't know how to include the second field in the syntax.
I am trying to create a one-to-many relationship between these two tables. I want to be able to access the 3 fields on the [Processors] table within reports based on [AllItems]. [AllItems] is a listing of account activity where the [AccountNumber] repeats. I have every field set as the "Primary Key" on [AllItems] as that is the only way to avoid importing duplicate data. I am getting the error: "no unique index found for the referenced field of the primary table"
