Forms :: Warn A User If Record Already Exists?
Dec 2, 2013
What is the best way to warn a user if a record already exists?I've looked at some examples that use an SQL SELECT statement with a recordset to compare existing records against the one the user is entering but i'm not sure which event this should be triggered by - eg; would it be the control's 'After Update' ,on 'Dirty' or 'Change' event? Would the record have been saved when the 'After Update' is fired- if not then it would not be found in the recordset and the SQL would not work....
how to create a textbox function that automatically searches and completes the textboxt based on exisitng records (like the cell autocomplete feature in Excel)? This could then populate the form with the existing record fields (if found ) and the user could update the record if necessary?

I am making a simple database for the computer laboratory in school (my place of work). Actually it is a Automated Logbook System. Here's the Problem. I want to make a form that will prompt me whenever I enter the data(ID number) of the user(student) 3 times already for the current week.
The message box will more likely prompt.
The Data already entered 3 times this week!!!

I have a simple application where a user clicks on the name of the person he wants to update from a drop down box.
The record is then retrieved and the fields are filled on the form.
The user will then enter a value in the # in household field.
The user is then required to click on the save button to write the record for this person.
I do not have strong users and they invariably forget to save the record and go on to the next person, resulting in the record not being updated.
I coded a message box as part of the save button which displays "person was successfully updated" and then instructed the user to make sure that they see this message before they go on to the next person. They still fail to update correctly.
My question:
Is there a way when the user selects a person from the drop down box and it is loaded on the form, to warn the user that they have NOT updated this person, before they go to the next person?
I don't know what else I can do with these users. They are all volunteers and elderly and the application is for a Food Pantry.

I stumbled upon the Option Group function just yesterday and, happy as a clam, I created a group with 2 options in radio button style. I assigned the values to a field called Registration_Type as the 2 options are "Confirmed Registrants" and "Prospective Attendees".
[Great. That part works well. When I look at the table, a 1 or a 2 is in that field so it's great to know how to control accidental ticking of radio buttons (previous 450 records or so didn't have this option group functionality so one might easily tick one of the buttons. So one part of controlling option group I know I can handle via the table itself for now.]
The challenge is how to ensure the user always ticks one or the other ... I went back to the main table and tested the 'required entry' option for the Registration_Type field but forcing an action like this is not ideal in my mind. The usual error message vagueness for the average user is no good and I don't want to limit the user so much.
Is there a way to simply have a popup come up warning that neither radio button was ticked? Perhaps something linked to the form - i.e., maybe "after update"?? I only learned about attaching code to before and after update on controls a couple of days ago, so not sure if this would be best approach.
Just something to let the user know that nothing has been ticked in the option group as that controls in which of 2 reports the data will show up in so any record not ticked might mean a registrant being left out, which would be rather disastrous <g>.

I have a table with a 3-part primary key. Have a form with 3 unbound controls corresponding to the 3-part table key.
After the 3 form fields have been entered, I want to search the table to see if a record with the same 3 fields on the table exists. If it does I want to go to another form to enter data for a related table carrying forward the 3 key fields.
If it doesn't I want to go to a different form to keep the 3 fields already entered from form 1 and add additional fields to complete the record.

I have a database that involves a lot of data about ppl and I'd like to prevent duplicate entries.
I have a form that gathers data. I'd like to have a button after name, surname and birthday are written.
A click on the button would display a msgbox that says that person already exist, maybe even with the added - edit the old entry/add new record anyway/abort options.

I have a database for mutli users which is split. Front end is available separately for 3 users. These users make data entry in the same form from their front end form. This particular form has combo box that retrieves data based on selection in combo box and the use starts filling the data in the subform. Upto this, form is Ok, no problems seen.
But when the second user opens the same form from the split database front end stored in his computer, and once the second user selects another record from the combo box, first user's record also changes immediately to the record of Second user. Both users now have the same record even though the form is separately accessed from front end.

Hello everyone,
I've made a form where the user can fill in a field ID... and than by clicking on a button another form will be opened with the data of that person (with that ID that's filled in). But if the user fill in an ID that is not currently in the database, there will be also shown another form, but than with no data.. Now I want that if the ID is not known, to display a message or something (like "this ID is not known, try again") and not to open the form..
I've used the following code under the button:
Private Sub openenFormulier_Click()
On Error GoTo Err_openenFormulier_Click
Dim stDocName As String
Dim stLinkCriteria As String
stDocName = "Onderzoek"
stLinkCriteria = "[Qr_Ant_PG.ID]=" & Me![ID]
DoCmd.OpenForm stDocName, , , stLinkCriteria
Exit_openenFormulier_Click:
Exit Sub
Err_openenFormulier_Click:
MsgBox Err.Description
Resume Exit_openenFormulier_Click
End Sub
Hopefully someone can help me!
Thanks,
Ankie

I have a table (tblSales) with these fields (RecDate, Code, Type, OrderCount).
I also have a linked table (lnkSales) with these fields.
Daily I append the data from the lnkSales to tblSales.
The tblSales table must have a record for each code daily.
These are the codes (01,02,05,07,09,10,15).
I need to automatically add a record for each code that wasn't appended.
For example,
lnkSales contains:
03/22/06 01 Mc 3
03/22/06 02 Mc 1
03/22/06 05 Mc 1
03/22/06 07 Mc 2
03/22/06 10 Mc 1
When appended to tblSales there is no record for code 09 or 15.
I need to add these records to tblSales
03/22/06 09 Mc 0
03/22/06 15 Mc 0
Can someone explain the best way to accomplish this?
Thanks.

Hello
I am trying to figure out how to make my database check to see if the primary key value is a duplicate of anything ive entered previously and if yes, for my database to bring up that record instead of adding a new record.
I know how to do bring up records using a separate combobox (find) but I cant seem to do it using the primary key field itself.
Many thanks in advance.

Hello all,
I have a form that looks at my "master table" where users put in general info about a sheet of material.
There are two combo boxes on this form, Batch# and Lot#. They will use the same Batch# and Lot# for many sheets. Every time a new batch and lot are entered, this will bring up a pop-up form where the user needs to take a measurement of that batch and lot for QA. This will go into a different table, where the batch and lot #'s are unique(many of the same batch#'s with different Lot#'s).
After the lot# is entered, I want to run a query in VB that looks for those unique identifiers, and if it doesn't find a record, my pop-up form will run.
This is probably something very easy....... It was a very long weekend and I'm tired of thinking.
Thanks
Scott

Hey all,
Tables
ProductsProductBrandSize
PurchaseDetailProductPriceQuantity
Forms
frmFoodSub
Combo BoxesiProductiBrand
TextboxsiSizeiQuantityiPrice
For a couple of days now I've been trying to devise a way to achieve what I want, but I just keep going in circles and hitting errors (thanks to forum members, I've been able to solve most of them.) So, here's what I want to be able to do:
Input a product using the iproduct combo box (which gets its list of values from the Products table); its brand, using the ibrand combo box; and its size using the isize textbox, all in the frmFoodSub form. I then want it to check to see if an exact record already exists (ie. the same product, same brand, same size.)
If it doesn't exist, I want to create it. If it does, I want to do nothing. Then I want the product - either the one I just created, or from a record that already exists matching the iProduct input - to be input into the product field of the PurchaseDetails table. I then want to use iQuantity and iPrice textboxs, already linked to the PurchaseDetails table, to input the newly added product's quantity and price.
I hope my explanation was clear enough. I'd appreciate any help with this you may be able to offer.

I have created a form which enbles users to enter data into the fields which will add a new record to my table. What I am trying to do now is to create some kind of validation rule that will check whether the record already exists.
I need it to work this way; there are four input fields- 3 text and 1 is a date filed. When the user enters a new record they are not allowed to create a record that conatins the same combination of values. So if one record has for example filed 1 = 1 field 2 = abc field 3 = def; then no other record can have the same combination of values.
If the user enters an already existing combination there would be an error message saying which field is incorrect. If the combination doesn't exist it would add the record and display a message that the record was successfully added.
How can I do this?

I have a form, which has a combo box which a user can select an employee - the combo has three columns (Employee_Number, Surname, Initials) although the Employee_Number column is set at a 0 width, so not visible.
The form is bound to a query which only shows records that are 'Active'
When a user selects and employee in the combo box, I want the AfterUpdate event to check and see if there is already an active record - if there is, throw up an error message and then reveal a couple of buttons giving choices what to do next; if there isn't an active record, reveal three textboxes and then populate those textboxes with the values from the three columns from the combo.
The bit that is sticking me is the search - - I have tried DCount, but can't seem to get it to work
Here is the section of code that I am battling with:
Code:
Dim EmpNo As String
EmpNo = cboEmp_Check.column(0)
If DCount("Employee_Number", "Incomplete_Training", "Employee_Number=" & EmpNo) > 0 Then
MsgBox "Existing", vbOKOnly

I am trying to check if a record exists in a table.
Dim cert As String
Dim existingRec As Variant
existingRec = DLookup("[Certificate]", "[Fire]", "'cert' = 'cert'")
If existingRec = Null Then
Else
MsgBox "The Certificate " & existingRec & " is in the database"
End If
Note - Certificate is a column in the table "Fire"
Problem is that existingRec only finds the first value in the Certificate column, How do I get to check the entire Certificate column?

I am working on a form and I only want the information to be inserted into the database if the user clicks the button at the bottom. In other words, if the user is filling out the form and then closes the form, I do not want that record saved.

I am creating a form that has a bunch of yes/no box for daily task. Is there a way for access to record which user selects yes/no.
For example
yes/no box1 - user 1 completed this task
yes/no box2 - user 2 completed this task
and so on
So when i look back i can see which user complete which task. I did a bit of research and saw that i can save a user that update a record. But since this is a daily task, each new record will be a new day.

I have a form that allows the user to select a record in a combo box. When this selection is made I want a 2nd form to open and give the user a place to enter additional info about that item selected. I have the forms working correctly but now I would really like to add the 2nd form to the first form as a subform but when I try this I get the message"The expressing is typed incorrectly or is too complex to be evaluated..." There are no fields on the first form that link directly to the 2nd form - because the combo box in an unbound combo (the selection in the combo box is what the 2nd form opens base on) I tried to add this as a subform with no parent/child info and I get the message stated.
I was hoping to make the 2nd form not visible until the selection was made in the combo box then make it visible for the info to be entered. Would really like it to be on the same form not as a separate form opening.I believe I just found that the reason for the message. It seems not to be a subform problem but is because the selection in the combo box needs to be made BEFORE the form can open. So now the question is - how can I make this a subform and avoid this error when the main form first opens. I will test the visibility and see if not visible until the selection clears this up.

Hi,
In the current db there are some tables and queries, forms designed around them
With one table Test
http://members.optusnet.com.au/~lukechang/access/table_d.JPG
That has 3 records in them
http://members.optusnet.com.au/~lukechang/access/table.JPG
Just won't show in form anymore, at this stage
http://members.optusnet.com.au/~lukechang/access/form.JPG
The Form was working previously. This is the second time this problem has came up, I thought it would go away if I made a new form and pasted all the controls and codes. It indeed went away for a while until this problem hit me again...
This db is in Access 2000 format and designed using Access 2003
I would appreciate if anyone is willing to point me to the right directions, many many thanks in advance

I have 2 tables:
Query_Rates (Actually this is the result of a query):
Unit
R_Date
Sold_Rate
A
24-AUG-15
145
[code]...
So what I want is a list of all the records from the Query_Rates table where the absolute differences between the sold rates between Query_Rates & [Sent till date] (matching the unit # and the dates) is greater than 1 and the record shouldn't be displayed if it is already present in the [Sent till date] table. But if you notice the first record which has unit A is already mentioned in the "Sent till date" table and shouldn't be repeated again in the query result.
The desired out put should be:
Unit
R_Date
Sold_Rate
X
25-AUG-15
200
