Warning Message For Duplicate Entry
Nov 27, 2006
I have struggled with this for so long now I hope someone can help.
I have a form called frm_Collections which is run from the query (qry_Collections). When I type into the Reg field in the Form I would
like the user to know if the Reg details have already been used in a
previous record. The database can have duplicates in this field, however a
"Warning Message" would promt some investigation.
I have tried loads of DLookup on Before Update, but really need setting of
in the right direction.
Thanks

I have a data entry form linked to a table that records daily catch details (date, invoice number, buyer, kilos, price, etc). For the last 2 years I've been using the no duplicate index on the date field of the table to prevent duplicates, until he (my husband) decided that he wanted to sell his catch to different buyers on the same date.
I've changed the index to allow duplicates but now I need to create a message box which warns that he is entering a duplicate date as he has a history of trying to enter the same info twice. I've found examples of code that warns on duplicate text entries but nothing for duplicate dates?

Hi!
I have a form which is based on student records. What I'm trying to get Access to do is to bring up an error message as soon a duplicate student number has been entered. At present I've managed to replace the Access standard error message 3022 with my own by using the following code:
Private Sub Form_Error(DataErr As Integer, Response As Integer)
Const conDuplicateKey = 3022
Dim strMsg As String
If DataErr = conDuplicateKey Then
Response = acDataErrContinue
strMsg = "Duplicated record. Please recheck your data."
MsgBox strMsg
End If
End Sub
However the error message only appears when you try to leave the form (e.g. start a new record). I would like the error message to appear as soon as the user leaves the Student Number text box on the form. Is there anyway to do this?

I have a single table in my database and I have to make a form for entering contact details for clients, staff, funding bodies and everyone else into this table. There is a phone number and what code I would use the get it to check if the number already exists.
If it does, I wanted it to return a custom message telling you what entries it already exists for by displaying certain fields so that they can be identified, such as name and organisation, but then I wanted the custom message to allow you to confirm entry of the data anyway. This is because there may have been an error in entry or as some people may be contacted on the same phone number, I want it to allow the option to continue and enter the data anyway.

So now, I'm using the code below to prevent duplicate name entry and it is working great - EXCEPT when I enter a first or last name which contains a ' (ie, O'Tool, O'Malley, O'Hern)...anyone got any ideas for me on how to make this not happen?
The error I get is:
Run Time error '3075'
Syntax error (missing operator) in query expression '[Last Name]='O'Hern' And [First Name]='Lori'.
The code i'm using is:
Private Sub Last_Name_AfterUpdate()
'Check for duplicate first and last name using DCount
If DCount("*", "[Constituents]", "[Last Name]= '" & Me![Last Name] & "' And [First Name] = '" & Me![First Name] & "'") > 0 Then
Beep
MsgBox "This first and last name already exists in the database. Please check that you are not entering a duplicate constituent before continuing.", vbOKOnly, "Duplicate Value"
Cancel = True
End If
CustID_Exit:
Exit Sub
CustID_Err:
MsgBox Error$
Resume CustID_Exit
End Sub

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 running Access 2002 on Windows XP Pro and have been teaching myself this program. I have created a large contact database with one main table and associated forms for entering data as well as reports driven by queries. What I can't figure out is how can I get a warning message to appear if a user enters a possible duplicate individual into a form. For example, if someone is entering an individual into a form that is bound to the main table and the same last name belongs to an individual already in the table, it may or may not be a duplicate. I'd like to learn some way of immediately checking the potential duplicates and then deciding weather or not to continue with the entry. Thanks much, in advance for any suggestions.

Hi there,
I apologise if this has been answered, I couldn't find anywhere else on the forum.
On the data access page it gives an annoying warning that says 'This website is using your identity to access a data source. If you trust this website, click OK to continue, otherwise click cancel'.
Is there a way I can suppress this message? It looked cool at the start, but now it's just annoying....
Thanks!

Hi all,
I am building a simple db from scratch using the limited knowledge i have, and a lot of the information gained from searching these forums as a guest. I've now reached a point where I can't seem to find what I'm looking for, so any help would be gratefully received!!
I have a single table, single form and single report (told you it was simple;)). The table has nearly 2000 records and 2000 pictures (linked). On the form I can print every record with a single click of a command button. This is great, but I would like a message box to popup and confirm the print action, as this is gonna be expensive if its clicked on every record!!
If anybody can help, I would be chuffed!! I searched the forums and can't seem to find anything on this!!

I have an Access 2010 db on a shared network drive. All users accessing the db are running Windows 7 OS and have a licensed corporate version of Access 2010. The advanced options "Shared", "Edited record" and "Open dabases by using record-level locking" are turned on. Additionally, the locking time limits are set to their default levels. If a user selects the save icon after making additions or updates, the following waring message appears:
Costar Job Database can't save design changes or save to a new database object because another user has the file open. To save you design changes or to save to a new object, you must have exclusive access to the file.Since I developed the db, I am the only one that makes design or object changes. I know that users don't need to select the save icon to update the db, but I don't want them to "freak out" if they select save and see the message.
Is there any way to prevent the message from being displayed?

I have a temporary table within my access database. I have a macro button that makes the table (thus deleting the old one in the process) and then appends information from three other queries to it.I want to stop the standard warning message from coming up. The message I get is below. I have already cleared the action queries check box so the warnings for the making table (if no previous table exists) query and appending data query have disappeared. However the below message still pops up when the make table query begins to try and delete the old table. How I can make it go away?
"The query you are about to run is a make-table query. Unlike most queries that displays data in Datasheet view, a make-table query creates a table and copies specific records from one or more tables and queries. If the table already exists, the query will replace the structure and contents of the table.If your intention is to create or replace a table, click Yes. To avoid being prompted when you run such queries, click the File tab, then click Options. In the Access Options dialog box, click Client Settings. Under Editing, clear the Action queries check box.

I do have a DB that takes some data from Stripes and imports them into access. Since this will be a multi user DB I want to make a warning form.
Basically a user will do the download, I want a form or a pop up message that will show to the next user that will open the DB while the download process is ongoing, to see that the download data process is still ongoing, That he needs to wait until the data download has finished.

I have a table (ComponentT) of different device components a user can select from ( generators, gearboxes, etc.)
The table has 3 fields - ComponentName, ComponentType, ComponenentDetails
I have a query returning all the ComponentDetails values.
I then have a combobox that uses this query as a row source.
The user can select different components they want from the combobox. Once something is selected, it is added to a new table - UserSelectedComponentsT
As a device can have only one gearbox or one generator etc. I want a warning messagebox to be displayed if the user tries to select a generator from the combobox when one has been previously selected.

I tried using a message box to try and validate text entry on a form into a bound txt box 'PaymentAmount', If there is no payment entered, using the properties box Validation Rule ,- 'is not null' then entered a validation text ="Please enter an Amount" but this does not work. How can I get a message box to appear if someone leaves the entry field empty so that they have to make some entry to move on. I have already entered this in the table validation field as well as 'Required - yes', but the message is an Access one not my own. Where or how do I do this ?

hi,
the below scrip was taken from another forum member.
i have put this in the Forms / error VBA
but i still a little lost
i have set 3 fields to be indexed not to allow duplicate information (Forename, Surename, DOB)
i was then advised to error trap so it would highlight that i have enterd a duplicate record on typing in the DOB (As that as third feild to be entered)
so i then used the below script, however this doesnt highlight that it is a duplicate it just doesnt let me go on to the next record, the only time the error message is highlighted is when i go into design mode.
anyideas on where to go from here.
Private Sub Form_Error(DataErr As Integer, Response As Integer)
If DataErr = 3022 Then
Response = acDataErrContinue
MsgBox "Tis MerID alredy exist!"
Exit Sub
End If
If DataErr = 2169 Then
Response = acDataErrContinue
MsgBox "Tis record will not be saved!"
Exit Sub
End If
End Sub

I have a Timesheet form where you select your name from a combo, and you select a Timesheet Period from another combo. Then you can enter various details in the sub-forms.
I want to prevent a user from being able to enter two timesheets for the same period. What's the best way of achieving this? I would like a pop-up to appear saying "You have already started a timesheet for this week. Please use the Update Form Dialog"
The timesheet form is bound to tblTimesheets which contains fields TimsheetID, StaffID, and TimesheetPeriodID
In cboNameSelect, StaffID is bound
In cboPeriodSelect, TimesheetPeriodID is bound.
Thanks

I have a form - see attached image.
The first text box is called Job_No. When a number is entered here how can I check that the number doesn't already exist when the user tabs to the next box. Then if it does exist display a custom message to the effect "This already exists" and not the Access default duplicate error message.

Hello to you all, it's my 1st post here…
How can I change the default message (as you can see in the picture) that appear every time that I try to update my record?
I want to write something like "You Have to select a different Number"
And one more question, the message only appear when I'm pressing the record selectorbutton only after the user has already filled all the form) is there a possibility that I can write a code that will check for duplicate data immediately after the user typed it?
Thanks for your help
David
