Modules & VBA :: Prevent Duplicate Records To External CSV File From Form
Nov 24, 2014
I have some code which creates a record in an external csv file to provide information to upload a vehicle to the website. It works fine with the exception of creating duplicates when, for example an option to amend a record is given to the user before continuing to a new record. The option has to be in place in case there is an error in the specifics of what is important to be recorded in the database and under such circumstances the form code allows the user to tab through the form and correct any errors, but this creates duplicate entries in the csv file as the user has to pass through the 'SavePrintVehPurch_Exit' button a second time after corrections are made.
I am wondering if there is a way of altering the following code to effectively look look to see if the csv record exists and if so correct any changed field information rather than create a whole new record or create a new record where the record does not exist - The record in the csv file is determined by the 'Me.VP_VehRegMark.Value '.
Private Sub SavePrintVehPurch_Exit(Cancel As Integer)
Dim fileText As String
Dim fileName As String
Dim fileNumber As String
fileNumber = FreeFile
[Code] ....
I am wondering about introducing the something like the following ( but can't work out how to clarify comparison of the fields)
If Len(filename(fileText)) = ? Then
Do not change entry
Else
Overwrite the new detail
Im trying to prevent duplicate records based on a PO # (RA_PO_Nbr), entered from a form. I'm trying to throw a 3022 error when the user attempts to enter a record that already exists, but I dont necessarily have to do it this way.
Code: Private Sub cmdSubmit_Click() On Error GoTo cmdSubmit_Click_Error Dim db As Database Dim rst As DAO.Recordset Dim strSQL As String strSQL = "CompanyPOTable"
I am using a data entry form to enter new data into one of the tables.How can we prevent entry of duplicate records? Duplicacy shall be checked on the first two fields only. Please help. regards bijon
the proper code to prevent duplicate records in my form?
I'm using:
Private Sub Ctl_Lname_BeforeUpdate(Cancel As Integer) Dim dupCount As Long dupCount = DCount("*", "Clients", "[LastName]= '" & Me.[LastName] & "'" & " And " & "[PreferredName] = '" & Me.[PreferredName] & "'") If dupCount <> 0 Then Beep MsgBox
[code]....
"This name already exists in the database. Please check that you are not entering a duplicate person before continuing.", vbOKOnly,
I have a table for storing vehicles. The table contains the following fields:
VehicleID Make Model Trim Build Date Begin Build Date End
Vehicle Name - a concatenation of 'Make' 'Model' 'Trim' 'Build Date Begin' and 'Build Date End'
The 'Vehicle ID' is the primary key, the rest of the fields can't be indexed with no duplicates. Is there a way of preventing one from saving a duplicate VehicleName on the table since it is a calculated field.
how or what function (DLookup) should I use to prevent duplicate records based on multiple fields? I want to look at data in three fields that can't match existing data in those three fields. It's ok if one or two of the fields match but not all three.
I currently assign multiple 'skills' to departments using a listbox and a combo using the following code
Code: Private Sub cmdSaveReq_Click() Dim strSQL As String Dim db As DAO.Database Dim rs As DAO.Recordset
[Code]....
However as time goes on we may want to add new skills to the depts - ive used dcount to check if the data exists in one field before however how would it be possible to check to see if the data combination exists over deptid and skill
If expression to determine if a duplicate records has been entered.
DateAte is a date MealType is a list box (text)
All I want to do is prevent two lunches, etc. from being entered on the same date. Code that results in the message box every time, regardless if a duplicate record or not.
Private Sub MealType_AfterUpdate() Dim strDA As String Dim DA As Date DA = Me.DateAte.Value strDA = "[DateAte]=" & "#" & DA & "#" If DCount("[MealType]", "tblmeals", strDA) > 1 Then
I'd like to prevent for duplicate time/date for same GuideCode. How can i prevent for those during the entry time or save time ? Is it possible ?
Capture1.

1. AUNKZ(GuideCode) is already assigned in other file number(12345) for 03-Aug-14 (as 02-Aug-14 to 04-Aug-14).
2. TOD(GuideCode) is already assigned in same file number(23456) for 10-Aug-14, 12:00 PM (as 10-Aug-14 to 10-Aug-14, 8:00AM to 1:00PM). I'd like to prevent if the file number are same or not same.
I have searched through the whole posts but could not find my query. I have a question related to prevent duplicate data entry in a form field.
I have a Form with 5 fileds on it: SNO, NAME, ROLL NO, CLASS, SECTION.
in the table design i have set the option of NO DUPLICATES on SNO(Autonumber) ROLL NO (text).
I wish to stop a user entering duplicate data in ROLL NO field before he reaches at the last field. What i meant is as soon as a user enters data in ROLL No field, it should check in table if the same data is already there. If the same data is found then it should give a message to prompt user of duplicate data, else it should continue to next field.
I have searched the whole forum but in vain. I am positive that there must be some one who holds the key to this solution.
I have a table with an attachment field called email, where a .msg file is stored for each record. Looking for code to save this contents of this field in a folder in my drive.
We are working on an Access (2007) database that is on a SharePoint Site (2007).
Currently the form is operational, but there is one last thing that would be nice to have.
The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.
In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.
All data is currently bound, so once the user makes a change it is made, no submit button is required.
We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.
TABLE - UPDATED HEADCOUNT COLUMN in UPDATED HEADCOUNT - EMPID FORM CELL user will input an EMPID - newEMPID FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID
So below is what we are trying to do, we are sure there are a few commands missing....
I would also like to automatically attach on the server to this email. Such a file stored such as servernamesharefilename.pdf. Is it possible to do this?
Been experimenting on some code to prevent deletion or changes to records that meet certain conditions.
The problem I am having is the code is contradicting each other preventing some of the records to be locked down.
Code: Private Sub Form_Current() 'Code 1 - Prevent edits if 21 day period has lapsed If TestDate2(Me.txtStartedHidden) > 0 Then MsgBox "Editing NOT allowed - 21 day time period has been reached" Me.txtBasic.Locked = True
[Code] ....
Rules are:
Edits allowed if invoice date not reached Edits allowed if within 21 day but NOT if invoice date is reached
Edits prevented if invoiced date reached and if records still within 21 days Edits prevented if invoiced date reached & records past 21 days
I am creating a small Access application that will allow me to update my Call handling system's site table. It uses an mdb file, and I wish to add new sites (from new contracts) to the SCSite table.
I recieve regular updates of new sites from existing customers, so want to create a simple macro that will
1: import (from an excel file) the new sites and add these to the existing SCSite table 2: Check for duplicate records using the Site_Num primary key 3: Merge non duplicate records into existing SCSite table.
Is this possible, and if so - how? VBA? Macro builder? Query?
A Swift response would be great, I have had a look through previous posts - but to no avail!
I have a recored set and i dont want a duplicate of the record set in the same table.
Say if my table name is businessskills and contains three fields(columns) and their names(Email , B_code, Rating) highlighted in red with data are as below
I've set up a booking system and am looking to stop the system recording double bookings.
I've 3 fields, RoomID, Date and Time that need to be searched, however I can't just simply set the properties to No Duplicates (as this would mean a booking cannot be made on the same day at 9:00 and 12:00 for example).
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."
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
I have a form that contains 5 fields and want to ensure that duplicate information is not entered. I am aware that when creating the form you can set Duplicate Records to No but each record has an AutoID which I assume means that even if the information is the same it will not register as a duplicate record due to the different AutoID.
There should only ever be 5 records entered per day. One for each region
I have created a Sanity Check that is displayed as a sub form that shows if the relevant information has been entered for a given day in Bookings and Backlog but this doesn't stop the user from putting in the same information twice. i.e. the User starts inputting the information gets called away and then trys to put it in again but doesn't check the sub form.
The Table in which the information is stored is called Bookings and Backlog.
The 5 fields on the form which is called Bookings and backlog are
ID (Autonumber) Date (Short Date) Combo26 (Text) (5 Regions:- North, South, East, West, Central) Bookings (Number) Backlog (Number)
I have put the following statement in AfterUpdate on the Combo26 field
If Me.Date = DLookup("[Bookings and backlog]![Date]", "[Bookings and backlog]", "[Bookings and backlog]![Date]=[Date]") And Me.Region = DLookup("[Bookings and backlog]![Region]", "[Bookings and backlog]", "[Bookings and backlog]![Region]=[Combo26]") Then 'Define Message Box MsgBox "The Region you have chosen already has data entered for this day." & vbCrLf & vbCrLf & "Please check your records and amend were neccessary.", vbCritical, "USER INPUT ERROR" Else End If
However I'm not to hot with writing VBA and probably got something wrong somewhere as it doesn't seem to do anything and lets the user progress regardless. I have tried amending the above script and asked it to look at just one field but this just seems to give the message regardless of the information selected in the Combo box.
Can someone give me an indication as to what I have done wrong so I can put it right and in a language that is easy to understand so that if I have a similar issue later on I don't need to post another question.
Hi all: I currently have a database with a list of clients, and it is to be accessible to others to enter information on clients and to add new ones. However, I want to make it so that the user who wants to add a client can easily search the database for that particular client so that they won't enter a duplicate.
I have created a search function on my form, but then it occurred to me: what if there are two people with the same last name's? At first, I wanted a search operation to display a list of client names, along with their respective ID numbers and possibly a link next to each that would take the user to the corresponding record.
However, I have no idea how to do this, and I'm unsure as to whether or not this is the best way to tackle the problem. Please, someone show me the way!
I am putting the student names in a form. I want it to alert me that a name is duplicated. But thats not this simple. For example a name is Jennifer Locus but I type jenifer with one . Can access guess that this might be the same person and suggest me to correct the spelling or enter it as a new person?
