I'm trying to input an error check for my form. I have the user entering the name and I would like a prompt to inform them if they are attempting to use a Name already in the records.
Example: the Person table has 3 records with FNames being: Jeff, Kyle, Darren.
If on the add person form in the Fname Box Kyle is entered, the after update event will notify the user that this name has been claimed and null the field. Where as if Greg was enter no notifications will occur.
I just don't know how to compare a text field value to values in a filtered query list, and Google searches have other loosely related links in the way.
Thank you for help!
If all fnames must be unique, add a unique index to the table. This will prevent duplicates being entered. The form error property will allow you to provide a custom error.
You can also check if the name exists in the Before Update event of the control.
In this example, the control and field are both called AText. Generally, you should rename controls so they are not the same as fields.
Private Sub AText_BeforeUpdate(Cancel As Integer)
Dim IsOk As Boolean
''One of the very few places where the .Text property is used
sLookUp = Me.AText.Text
IsOk = IsNull(DLookup("Atext", "Table1", "Atext='" & sLookUp & "'"))
If Not IsOk Then
MsgBox "Found!"
Cancel = True
End If
End Sub

I'm trying to create a data entry form in Access (2016) & wish to only permit values if they already exist in the product database.
My desired end result would be similar to the below:
User inputs: B8631
I would like Access to lookup that input value against Item_Master.Primal_Code and only permit it as a value if it exists already, rejecting it if it doesn't.
You can use the Dcount function to validate the input. See below
Dim userInput as string
userInput = "B8631"
If Dcount("*","Item_Master","Primal_Code='" & userInput & "'")<=0 Then
msgbox "not found"
exit sub
end if
Another question that stumps me.
I have a continuous form that shows a list of all of our clients at the law firm I work at here. Right now you can double click on a client name where a form (frmContactSummary) then opens up to display all the information for that client.
Problem is, as it is currently designed only one form can be open for a client at a time.
We want to be able to open multiple versions or instances of frmContactSummary.
I borrowed code from Allen Browne's site, which is as follows:
Option Compare Database
Option Explicit
'Author: Allen J Browne, July 2004
'Email: allen#allenbrowne.com
'Found at: http://allenbrowne.com/ser-35.html
Public clnClient As New Collection 'Instances of frmClient.
Function OpenAClient() 'ContactID As Integer
'Purpose: Open an independent instance of form frmClient.
Dim frm As Form
'Debug.Print "ID: " & ID
'Open a new instance, show it, and set a caption.
Set frm = New Form_frmContactSummary
frm.Visible = True
frm.Caption = frm.Hwnd & ", opened " & Now()
'Append it to our collection.
clnClient.Add Item:=frm, Key:=CStr(frm.Hwnd)
Set frm = Nothing
End Function
This works in a way, but it only opens up the first record in our Contact table. We want the instance to open on a specific record, or ID from the Contacts table.
I tried this code near the end:
frm.RecordSource = "select * from Contacts where [ID] = " & ContactID
But it did not work.. :-(
Any advise would be much appreciated! Thank you!
Ok, when you create a instance of a form, you can’t use the common approach of a where clause like this:
Docmd.OpenForm "frmContactSummary",,,"id = " & me!id
The above of course would work for opening one form.
However, in your case, you need:
Create a new instance of the form
Move/set the form recordsource to ID
Display the form
So we need a means to move or set the form to the ID of the row we just clicked on.
So right after we create the form, then add this line of code:
Set frm = New Form_frmContactSummary
Frm.RecordSource = "select * from Contacts where id = " & me!id
And rest of your code follows.
It not clear if the PK (key) of the table Contacts is “id”, or “ContactID”
So your code will be:
Frm.RecordSource = "select * from Contacts where id = " & me!id
Or
Frm.RecordSource = "select * from Contacts where Contactid = " & me!ContactID
Simply replace “ContactID” in above with a actual PK id used in table contacts. The "Id" has nothing to do with the collection. We are simply building a SQL statement that will pull/set the form to the one row. So the only information required here is what is the PK name in your continues form, and what is the PK name in your frmContactsSummary. (they will be the same name in both forms, and should thus be the same in the sql statement.
Searched around a bit and could not find an existing post with my exact question.
I am creating an Access (2003) database utilizing multiple forms and tables that need to communicate and share information with one another (i.e. - first/last name, etc.). The main form/table, "Personnel", will hold a majority of the information, yet the other forms/tables will only hold information pertinent to certain situations/circumstances, so not every entry in "Personnel" will have a concurrent entry in "Hired", for example. If a record with the same name already exists, I would like a MsgBox to tell me so and open that entry (in the form, for editing), if not a new entry would be created, auto-populated with pre-selected fields (i.e. - first/last name).
After an option is selected from a pull-down menu, the appropriate form is accessed/opened, "Hired", for example (This part works).
The copying information across forms does not work.
Dim rstPers, rstHired As DAO.recordset
Dim LastName As String
If status = "hired" Then
DoCmd.OpenForm "Hired Information"
Set rstPers Forms!Personnel.RecordsetClone
Set rstHired Forms![Hired Information].RecordsetClone
????
...
End If
I have tried to do this multiple ways but nothing seems to work. Nothing populates in the new Form or table. Am I looking at it the wrong way? Should I try a different approach?
Hope my explanation makes sense. Thanks for any help.

You have a bad approach indeed.
Your forms are linked to a table. So you should avoid as much as possible to manipulate or retrieve a form's data directly using a recordsetclone, instead try to retrieve this data directly from the table.
So if you want to open your "hired information" form:
Dim RS As Recordset
Dim IDperson As String
IDperson = me.ID ' or whatever
Set RS = CurrentDb.OpenRecordset("SELECT ID FROM TableHired WHERE ID='" & IDperson & "'")
If RS.BOF Then
' No record exist - Open form in record creation
DoCmd.OpenForm "FormHired", acNormal, , , acFormAdd
Else
' record exists, open form and position it oon the record's ID
DoCmd.OpenForm "FormHired", acNormal, , "ID='" & RS!ID & "'", acFormEdit
End If
Of course it won't work like this as you didn't provide enough info.
Review this code and adapt it with your fields name (IDs), table name (TableHired) and FormName (FormHired) and following the situation on where and how you will trigger it. Also if your ID is not a string, you should remove the quotes in the SQL
I have a form called 'detail' which shows a detailed view of a selected record. The record is selected from a different form called 'search'. Because I want to be able to open multiple instances of 'detail', each showing details of a different record, I used the following code:
Public detailCollection As New Collection
Function openDetail(patID As Integer, pName As String)
'Purpose: Open an independent instance of form
Dim frm As Form
Debug.Print "ID: " & patID
'Open a new instance, show it, and set a caption.
Set frm = New Form_detail
frm.Visible = True
frm.Caption = pName
detailCollection.Add Item:=frm, Key:=CStr(frm.Hwnd)
Set frm = Nothing
End Function
PatID is the Primary Key of the record I wish to show in this new instance of 'detail.' The debug print line prints out the correct PatID, so i have it available. How do I pass it to this new instance of the form?
I tried to set the OpenArgs of the new form, but I get an error stating that OpenArgs is read only. After researching, OpenArgs can only be set by DoCmd (which won't work, because then I don't get independent instances of the form). I can find no documentation on the allowable parameters when creating a Form object. Apparently, Microsoft doesn't consider a Constructor to be a Method, at least according to the docs. How should I handle this? (plz don't tell me to set it to an invisible text box or something) Thanks guys, you guys are the best on the net at answering these questions for me. I love you all!
Source Code for the multi-instance form taken from: http://allenbrowne.com/ser-35.html
Inside your Form_detail, create a custom property.
Private mItemId As Long
Property Let ItemID(value as Long)
mItemId = value
' some code to re query Me
End Property
Property Get ItemId() As Long
ItemId = mItemId
End Property
Then, in the code that creates the form, you can do this.
Set frm = New Form_detail
frm.ItemId = patId
frm.Visible = True
frm.Caption = pName
This will allow you to pass an ID to the new form instance, and ensure it gets requeried before making it visible. No need to load all of the results every time if you're always opening the form by Newing it. You let the property load the data instead of the traditional Form_Load event.
This works because Access Form modules are nothing more than glorified classes. Hope this helps.
You could try applying a filter:
frm.Filter = "[ID] = " & patID
frm.FilterOn = True
The Record Source of the Detail form will need to be set to the table to which the ID belongs.
UPDATE
As you requested, here is the code to set the RecordSource:
frm.RecordSource = "select * from TableName where [ID] = " & patID
This is probably cleaner than using a filter given that a user can remove the filter (depending on the type of form).
I have a question regarding updating new record through VBA.
First - the assumptions.
I've made a form called "assortment", that displays a set of records and a sobreport that shows related invntory. I've put the button on it: "Add new record". This opens the second form "inventory_details" that is intended to enter and view the inventory spcific data. That inventory is of that specific assortment type. So - I've passed the assortment_id to the inventory_details form through the DoCmd.OpenForm like:
DoCmd.OpenForm stFormName, , , , acFormAdd, , Me.assortment_id
The data source of the "inventory_details" form is a query that contains the assortment table joined to the inventory table by the inventory_id. What is the best way to add this id passed by an OpenArgs to the currently opened new record and refresh the form to show related assortment data?
I was trying to do this like:
Private Sub Form_Open(Cancel As Integer)
Dim assortmentId As Integer
If (Not IsNull(Me.OpenArgs)) Then
assortmentId = Me.OpenArgs()
Set rst = Me.Recordset
rst.Edit
rst.assortment_id_assortment = assortmentId
Me.Requery
End If
End Sub
but it gives me an error "3021 " No current record"...
Here are some suggestions,
. Make sure you define the variable rst
. Check for EOF Condition to make sure your recordset contains rows
If rst.EOF Then
MsgBox "The Recordset is empty."
End If
. Why clone an MS-Access recordset?
