Forms :: Warning On Duplicate Date Entry
Aug 14, 2014
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?

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 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.

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.

I have a Form created for Hardware Allocation.
I have following Fields. Allocation ID(PK), HW ID, User ID, HW Status, Assigned Date.
Values of HW Status = Active, Inactive, Decom, In Stock etc.
What I want is explaind below example
HW XXX is allocated to User ABC and the Status is Active.
Now When I want to reallocate the same HW XXX to Another User XYZ then Make the current status as Active. But before doing that the form should force me to change the Status of previous allocated to user ABC to anything other than active. Because One Device can be active to only one user at a time.
i,e Combination of HW ID & HW Status(Active Only) should not be duplicated.

I have a textbox on my form that is for "week of", always a Monday. There is vba to populate the appropriate Monday when the user selects something other than Monday via the date picker. This code is in the on change event. However, this is not friendly to a user entering a date in this field. I did try after update event, but that requires user to leave the "week of" field. This is not acceptable in this instance, there are other form fields that change as a result of this "week of" value.I also tried evaluating the length of the text or else exiting the code. However, I was expecting the date being returned from the date picker to always be 10 positions, but for March 3rd, it would return 3/3/2015...which is only 8 positions.

I have a date entry textbox.
The user is copying a date from an old form.
Sometimes the form will have the date entered as 00/00/97
How can I change the month and day to 01/01 and of course leave the year as it was.
I've tried using split with no success.

I have a database that makes use of standing orders. That means that if a client has a standing order to receive products during for example 4 time as year (quartely at the end of the month). to automate the new entry by copying an old entry in the database.
Let's say I have a client where we will have to send a product at the end of June, it will look at a field where the next send date is, and when it reaches 2 weeks for that date, to create a new entry in the database based on that entry. This way, it will pop-up in our open cases and we are aware of it and also will be visible in our report.

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 created a basic Volunteer Events and Hours Volunteered tracking database.
I created a form Volunteer Hours to allow an end user to use that form to record the volunteer and hours volunteered on a specific Event. There are two tables needed in the form Volunteer Hours to be used for the end users to record the Event, Volunteer, Date and Hours. The form has drill down fields from two tables:
Table A - Volunteer Events (event name, date, descr, owner, co-owner, loc, status)
Table B - Volunteers (name, co, div, emp#,title)
I want to be able to select the Volunteer Event and have the event date automatically populate in the Volunteer Hours form date field when the Event is selected to eliminate the end user from having to enter the date in.
Also; I would like to be able to add more than one volunteer at a time to an event on the form, this would also decrease the data entry time.
Are one or both of these things possible?

I am trying to create some sort of warning to show that a date in one of my forms will expire in say 30 days. I need the warning to be a pop up (or similar) rather than be sent via email (only because I don't have Outlook set up and probably will not be able to). Effectively, I have a list of names and a column in my table to show an expiry date. To avoid missing the expiry date, I would like to be advised of this at least 30 days before hand.

I have a table that has (to simplify things) two fields.
[Patient_No] [ID]
BA4206 1067404
BA4206 1067405
BG1013 1067545
BG1013 1067546
BG1013 1067547
BG1111 1078432
I want to be able to count the number entries where the Patient_No is the same and output the query like this:
[Patient_No] [ID] [COUNT]
BA4206 1067404 1
BA4206 1067405 2
BG1013 1067545 1
BG1013 1067546 2
BG1013 1067547 3
BG1111 1078432 1
Hopefully this is just a simple query but for some reason i cannot get it to work.
Any help is much appreciated.
Thanks in advance

Have read through all the threads related to this topic and can't find anything to help. Just want a message box to pop up after entry of first and last names in a form if the string already exists in the database. DLookup works wonderfully for validating on one field, but adding the second field is driving me crazy - Can I use DLookup to check more than one field? The following code gives me the error: "Run time error '2001' - You canceled the previous operation."
Private Sub LastName_AfterUpdate()
Dim x As Variant
x = DLookup("[txtLastName]", "[tblVolunteerInfo]", "[txtLast Name]= '" & Me![LastName] & "'" & " And " & "[txtFirstName] = " & Me![FirstName])
On Error GoTo CustID_Err
If Not IsNull(x) Then
Beep
MsgBox "This name already exists in the database. Please check that you are not entering a duplicate person before continuing.", vbOKOnly, "Duplicate Value"
Cancel = True
End If
CustID_Exit:
Exit Sub
CustID_Err:
MsgBox Error$
Resume CustID_Exit
End Sub
thanks,

I have a Form based on a table of current Players in a football league.
The Form is used to edit, but mainly add new registrations. The fields are...
Surname FirstName Address Suburb Age Club YearRegd
Is it possible in some way to have an alert or message come up stating that the Player is already registered if the Table already contains a player with the same Surname and FirstName only. This would need to happen after the FirstName has been entered as it is the second field after 'Surname'. I'm not sure if Access can do this type of function or not.
I've searched the Forums but have had no luck.
Any advice/assistance is greatly appreciated.
Thank-you very much.

I am extremely new to Access. I have my database up and running ok(ish) and would like to know if in my data entry form, I can have the "Date Entered in Database" box display the current date that does not change from day to day. I know you can use the "Now()" function but won't this just change everyday?

Greetings,
I am using Access 97 at work, Access 2000 at home. This is a work project.
I have a database that tracks employee awards. One type of award is the Peer Award. An employee can receive more than one award during the reporting period (01 May 05 through 30 April 06), but an employee can nominate someone only ONCE during this period. The query also filters all award for the word PEER in the Award_Type field.
I need a method in my subform (where all of the award info is entered) to display a message if the NOMINATED_BY field contains the name of a nominator more than once. I am using a combobox (cboNominated_By) to select the nominator from a query based on the Employee_Name table.
I had thought of making the field NO DUPLICATES, but cannot do that, as I also keep these records as multi-year archives.
In my query I have as the criteria to limit records for the reporting period above.
In my subform, is there a method to check the combobox that I'm using for a duplicate nominator, then notify the user of this duplicate?
I've seen something similar to what I want in the below thread, but FoFa didn't offer an example of how this would be accomplished;
Notification of Duplicate Records

Thanks all for any assistance you might offer!
