Modules & VBA :: Prevent Record Creation If Form Is Null?
May 11, 2015
Nutshell: My user DB has one menu with 4 tabs (2 for adding records, and 2 for searching/editing records). Since the form opens up in the acFormAdd mode, Access already creates a new record (blank) before they type anything. It is resulting in blank false new records that are getting added to the table and they are getting annoying. My audit table is full of "user X created new record at this time" when it's just a blank record.
There must be a way to prevent this using VBA, but I cannot find it.
I've seen ways to disable "add new record" buttons and such, but nothing that disables Access from being smarter than me and creating a new record before I decide to.
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 have a table that is a list of all of my events. Each record of events should have a child table that list all of the things that happened at the event. When a new record (event) is added how can I have a new child table created and linked to that record. Also I have a blank table to serve as a template for what each child should look like. How do I make sure this occurs? The child tables can have the same name as the index. I am just using numbers 1- for the index with 1 being the first event and so on?
I have a split form that's like a list of pending tasks. The data source is a linked SharePoint 2013 list where users submit requests. The user takes the information from each record and performs an action. When it is done, the user presses a button and the task status changes from "Pending" to "Processed". The form record source is based on a query that finds only records with a status of "Pending" so when the user changes the status of the task, it is removed from the list. It works fine except when there is only one task left in the work list. If the user processes the last task, the form refreshes and it goes to a new empty record and I get an error message that says I must enter a value into one of the required fields. I tried making the field non-required but it just creates an empty record in the table.
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
I've got this form called mainmenu and inside this form I've got this code to prevent it from being closed.
Code: Private Sub Form_Unload(Cancel As Integer) Cancel = True End Sub
Now then, when I try to switch to design view in this form it doesn't let me because of this code. Is there anyway to tweak this code so that I can get into design view without having to keep disabling it?
i want to have a feature in my database like the following..
these are basically day to day clock in times for my staff..
is there a way that everday.. a new record will be created..
eg.. on 04/06/06... i turn on my pc for the first time.. and when i view the timesheet form.. a record for today is automatically created.. then throughout the rest of the day, this form will be displayed..
when i turn on my pc on 05/06/06, the database will know its a different day, so it creates a new record for today... then i can just move back and forth throughout the days to see the details..
if i then turn my computer off for 5 days, then turn it on at 10/06/06, it still should have made records for 6,7,8, and 9th June, but they will be empty, and the record im shown is for the 10/06/06,
I been tasked with a project to be written in access which I am rather unfamiliar with, web design is more my area.
For part of the project I need to copy some pricing fields from a pricing table to a new record at the point that the new record is created. The new record is created when a 'new form' button is clicked.
What I would like to know is what and where I should trigger the copy query from and what function should I be using?
I have a subform with a lot of fields in which require input. I have set the tab order correctly so they go through in sequence. However, I have found when I tab out of the last field. Its creates a new record which I dont want.I want it to either return to the first field to just stop.
I would like access to automatically create a record in the contracts table when I change the status in one of the Customer Fields from prospective to Customer.
The two tables are linked using the Customer ID field.
I have a multi-select list box for selecting which faculty members apply to a project. The faculty table and project table are linked in a many-to-many relationship. I have the following code which should create entries in the link table:
Private Sub Command5_Click() Dim varItm As Variant
For Each varItm In lstFaculty.ItemsSelected rs.AddNew rs!FacultyID = Me.lstFaculty rs!EntryID = Me.EntryID rs.Update Next varItm
rs.Close Set rs = Nothing End Sub
It successfully creates new records and enters the EntryID and LinkID (autonumber). However, FacultyID is always left blank. lstFaculty is the unbound list box which has three columns from the faculty table and is bound to FacultyID. Any ideas on why FacultyID isn't created in the link table (I get no error messages)?
Also, any ideas on how to prevent duplicate links being created every time the button is pushed? I was planning on having it first run a delete query for that EntryID in the link table so that it replaces the old links and any that have now been unselected are no longer linked. Comments on that idea?
Thanks again to everyone on the forums for your help.
What I would like to do it take all 'RoleTitle' from RolesList, all 'CourseID' from courselist and show them as a pivot table/matrix with a checkbox that creates or deletes entries from the RoleRequirements table. So, if it exists in the RoleRequirements table then it should appear a checked, unchecking it would delete it from the table.
I am using access 2010 with a SQL server 2005 backend.
I think my question is fairly simple - fingers crossed.
I want to create a field that, whenever a record is added, it auto-adds the date & time the record was created. I'd call it Book_Date_Added, or something like that. I tried snooping around the Default Value options but couldn't figure it out.
The table exists and it already has some records, so I'd need to know how to add this field rather than how to create it when I create a table (although that would be helpful too, if it's somehow different).
It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code: Private Sub cmdUpdateDates_Click() '################################### 'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time]. '################################### Dim intCounter As Integer intCounter = 0 Dim rs As ADODB.Recordset
I'm trying to add a new functionality on my search form where the user can search for records that haven't been modified(based on the field DateModified) for certain amount of time.This is what I added in my search function but it's giving me "Invalid use of Null"
If Not IsNull(Me.txtInactiveTime) Then Dim LValue As Integer LValue = DateDiff("d", Me.DateModified, Date) Select Case Me.txtInactiveTime Case "> 1 month" strWhere = strWhere & "(LValue >= " 30 ") AND " Case "> 2 months" strWhere = strWhere & "(LValue >= " 60 ") AND " End Select End If
txtInactiveTime is a combo box where the user chooses the time during which the records haven't been modified.(i.e. 1 month, 2 months etc.)
I want to pass the Combobox value of one form to a textbox on another using the where condition. Using the break in VBA, the value of the combobox (in this instance "two") shows as null. the control of the combobox is [cboSubCategory] and I want it's value to pass to another form "tblCategoriesSub" (aware of the incorrect reference, as used wizard quickly - but will change if I can get it to work) to the "SubCategory" field.
I've got a form/subform showing employee/position details. I've disabled the regular record navigation buttons and put in ones of my own. If I'm advancing through all the position records for a particular employee using the next record button, when it gets to the last record, the next button advances to a new blank record. Because I'm prepopulating new record fields with previous record values, the users sometimes don't realize they've just created a new record. Is there a way to advance through records without advancing past the last record into a new blank record? I still need the ability to add new records on this form using the add record button I've created.
I have a form with couple of textboxes bound to a table. When the user opens the form to enter records, i want to write a function that would go through the textboxes to check whether the textboxes are left NULL. Now i can write code on button click for each form, but i was wondering if its possible to write a function that could be called for each form that i have to check for null values.
The unbound Parent form has a listbox (SQL Server) , the selection updates the SubForm with a primary key ID. The Subform is a ReadOnly view from an Oracle Linked table. It populates with a Select * From Oracleview where ID = listboxID The code is at the link shown below update: The subform uses textboxes linked to the read-only record.
The main form can populate, no problem. However the SubForm data source is either populated OR is Null.
If it is Null, the subform stays blank. Two Objectives:
1. Set a boolean variable flag in the parent (main form) that subform record exist or that it is null. e.g. Parent obtain recordset count property from Sub form 2. Display the subform with blanks.
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
My Database consists of three tables and a linking table, tbl graves, tbldeceased,tblmemorail and tbl memorialtablejoin.
Having completed my tables and checked that the relationship data gives the correct data I decided to embark on a simple form to display all the data on a single form.
So I used the create Form option, selected add existing fields. All of my tables are shown in the fields list.
From tblgraves I selected plot and grave Id, from tbl deceased forename and surname and from tbl memorial the inscription field.
The form was created but on examination I realised that my total records was shown as 12000 records whereas tble graves and tbl deceased has 39000 records and tblememorial 17000 records
So I created the form using just tblgraves and tbldeceased and that shows my 39201 records.
If I leave form view and go back to design view and add the inscription record from tblMemorials I see the message box as per the attachment.
Not every grave or deceased has a memorial but I would expect to see my 39000 records
I've also attached a screen shot of my relationships...
