navigating and updating in MS Access datasheet subform - ms-access

Im using the code below to loop through the recordset of a subform in datasheet view and update a field, so that I avoid doing a SQL update as I want to also manually update when needed and this way avoids the "The data has been changed by another user..." message.
My question is, if I have 10 records in the recordset but the cursor is on the 5th record down on the form, then only the records from that point on get changed, eg 5 to 10.
Should this not update all the records? I can't figure out why it's not.
thanks
Dim tmprs As DAO.Recordset
Dim fld As DAO.Field
Dim bkmrk As Variant
Set tmprs = Forms!frmtanks!Child67.Form.Recordset
bkmrk = Me.Bookmark
tmprs.MoveFirst
While Not tmprs.EOF
For Each fld In tmprs.Fields
If fld.name = "freeDays" Then
freeDays = fd
End If
Next
tmprs.MoveNext
Wend
Me.Bookmark = bkmrk

You should use the form's RecordsetClone to do your updates. This will not alter the active record of your form when you use the MoveNext/MovePrevious type functions, start from first record of the recordset, and not require you to move back to your record with a bookmark.
Dim tmprs As DAO.Recordset
Dim fld As DAO.Field
Dim bkmrk As Variant
Set tmprs = Forms!frmtanks!Child67.Form.RecordsetClone

While Not tmprs.EOF
tmprs("freeDays") = fd
tmprs.Update
tmprs.MoveNext

Read only recordset "local" update

I have DAO recordset that is generated with pass-through query to postgresql stored function. I use it to fill out combobox in my form. What I need is additional item in combobox with "AllItems" description. But the recordset is read-only (that's normal in this case). So I cannot just add new row to it. Can I do any kind of in memory recordset clone, copy or anything like that to make addition possible? I don't want to update recordsource. And I don't want to hardcode this option in to the pgsql function as well.
Public Sub fillCboAssortmentType()
Dim rs As DAO.Recordset
If (lngViewContext = acMyItems) Then
Set rs = getAssortmentTypesByDAO(TempVars!loggedUser)
Else (lngViewContext = acAllItems) Then
Set rs = getAssortmentTypesByDAO
End If
' It wont work, because the rs is RO
With rs
.AddNew
!type_id = 0
!type_name = "***AllItems***"
End With
' It wont work neither, because cboTypeFilter rowsource is Table/Query
Set Me.cboTypeFilter.Recordset = rs
Me.cboTypeFilter.AddItem "0;***AllItems***"
End Sub
Any suggestions?
TY All.
I think you are asking for a "In Memory" Recordset. Let's assume you have a table which looks like this
Then the following code will read the values from the table and copy it to a in memory recordset and add a new value but only in memory
Option Compare Database
Option Explicit
Sub inMemory()
Dim rs As ADODB.Recordset
Set rs = New ADODB.Recordset
With rs.Fields
.Append "val", adVarChar, 64
End With
Dim sourceRs As DAO.Recordset
Dim db As DAO.Database
Set db = CurrentDb
Set sourceRs = db.OpenRecordset("SELECT * FROM tbl")
Dim i As Long
rs.Open
Do Until sourceRs.EOF
rs.AddNew
rs.Fields(0).Value = sourceRs.Fields(0).Value
rs.Update
sourceRs.MoveNext
Loop
rs.AddNew
rs.Fields(0).Value = "Cancel"
rs.Update
' let's print the list just for testing
rs.MoveFirst
Do Until rs.EOF
Debug.Print rs.Fields(0).Value
rs.MoveNext
Loop
End Sub

Object variable or With block variable not set Access vba [duplicate]

This question already has answers here:
Vba Access error 91
(2 answers)
Closed 5 years ago.
I'm working with a couple tables, CTOL and CTOL_Asbuilt in Access. I'm trying to run a query to join these two tables together using VBA code. I ran the query in Access and it works. I'm using DAO for the database library to retrieve data from the local Access database (code is in the same database project as the database), and I'm new to VBA Access scripting.
SELECT CTOL.ID, CTOL.BOM_PART_NAME, CTOL.CII, CTOL.[PART FIND NO], CTOL.CSN,
CTOL.AFS, CTOL.EQP_POS_CD, CTOL.LCN, CTOL.POS_CT, CTOL.SERIAL_NO,
CTOL.PART_NO_LLP, [CTOL_Asbuilt].[PART-SN], [CTOL_Asbuilt].[PART-ATA-NO],
[CTOL_PW-E750207_Asbuilt].[PW-PART-NO]
FROM CTOL LEFT JOIN [CTOL_Asbuilt] ON CTOL.[PART FIND NO] = [CTOL_Asbuilt].[PART-ATA-NO];
This is the code below:
Option Compare Database
Option Explicit
'Const adOpenStatic = 3
'Const adLockOptimistic = 3
Function queryDatabase()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim rsQuery As DAO.Recordset
Dim part_find_no() As String
Dim eqp_pos() As Integer
'Dim strSQL As String
Dim i As Integer
Dim j As Integer
'Set objConnection = CurrentDb.OpenRecordset("CTOL")
Set db = CurrentDb
Set rsQuery = db.OpenRecordset("SicrProcess", dbOpenDynaset)
rs.Close
db.Close
Set rs = Nothing
Set db = Nothing
End Function
I'm getting the following error when I run this code with a macro that calls the function:
Run time error '91':
Object variable or With block variable not set
I'm trying to use the code with the query to loop through two fields and increment the value of the EQP_POS_CD field when the PART FIND NO entry matches the last (else, it just moves to the next record until it reaches the end of the result set). I want to test-run this query to make sure that the code retrieves the result that is output by running the query manually in Access.
Can you help me in fixing this error so I can run my code to retrieve the data? Thanks!
rs.Close
You cannot close something that is not open. Perhaps you meant it to be rsQuery.Close?
Open a recordset and loop through records.
Sub queryDatabase()
On Error GoTo ErrProc
Dim db As DAO.Database
Set db = CurrentDb
Dim qdf As DAO.QueryDef
Set qdf = db.QueryDefs("SicrProcess") 'set your query name here
Dim rs As DAO.Recordset
Set rs = qdf.OpenRecordset(dbOpenDynaset)
Dim part_find_no() As String
Dim eqp_pos() As Integer, i As Integer
If rs.EOF Then GoTo Leave
rs.MoveLast
rs.MoveFirst
For i = 1 To rs.RecordCount
'...
'Do work here
'...
rs.MoveNext
Next i
Leave:
On Error Resume Next
rs.Close
Set rs = Nothing
qdf.Close
Set qdf = Nothing
Set db = Nothing
On Error GoTo 0
Exit Sub
ErrProc:
MsgBox Err.Description, vbCritical
Resume Leave
End Sub

Access only filtered values in a MS Access table

Is it possible to get the values from rows in an Access table that are showing after the filter is applied?
Example as requested:
I have a table in which employees fill in project tasks, hours on the project etc.
It is made as a table on a form. The columns has limited choices in Initials, Project number, etc. People like to sort the table by the built in filter function in access tables and queries. I filtered so only the project LT1075 is shown in the example.
How can i get those 4 rows as a recordset or something similar? I need to get the values in all hour fields. I need also to copy only those 4 lines in VBA and do stuff to it (Functions wanted by people). But when i use the DAO, i get all rows in the "Unfiltered" table.
How do i get only the rows visible?
In excel, there is a simple function, something with cells_visible but i cant find a pardon to Access.
Best Regards, Emil.
Edit, tryouts:
Public Sub Test1_Click()
Dim rs As DAO.Recordset
Set rs = Me.RecordsetClone
While Not rs.EOF
' Do calculation stuff on record.
rs.MoveNext
Wend
End Sub
It is put on the "Test 1" button in the figure above.
I get the error: "Runtime error 7951 - You entered an expression that has an invalid reference to the RecordsetClone property"
I have a clue that it does not work because of the Me.* function? Since the table is in some sort of subform. But i see only one form in the Navigation panel. (Hidden are also showed).
You can use the RecordsetClone of the form:
Dim rs As DAO.Recordset
Set rs = Me.RecordsetClone
While Not rs.EOF
' Do calculation stuff on record.
rs.MoveNext
Wend
And you can add records to a recordset:
Public Sub CopyRecords()
Dim rstSource As DAO.Recordset
Dim rstInsert As DAO.Recordset
Dim fld As DAO.Field
Dim strSQL As String
Dim lngLoop As Long
Dim lngCount As Long
strSQL = "SELECT TOP 1 * FROM tblStatus"
Set rstInsert = CurrentDb.OpenRecordset(strSQL)
' rstSource can be any recordset, here the RecordsetClone of the form.
Set rstSource = Me.RecordsetClone
With rstSource
While Not .EOF
With rstInsert
.AddNew
For Each fld In rstSource.Fields
With fld
If .Attributes And dbAutoIncrField Then
' Skip Autonumber or GUID field.
ElseIf .Name = "Total" Then
' Special cases.
' Insert default job code.
rstInsert.Fields(.Name).Value = 0
ElseIf .Name = "PROCESSED_IND" Then
rstInsert.Fields(.Name).Value = vbNullString
Else
' Copy field content.
rstInsert.Fields(.Name).Value = .Value
End If
End With
Next
.Update
End With
.MoveNext
Next
rstInsert.Close
.Close
End With
Set rstInsert = Nothing
Set rstSource = Nothing
End Sub

openrecordset only showing one result

When I use a recordset to read from a table everything works fine and the recordcount function shows me the correct amount, but when I use this simple query or any query I always get 1 as a recordcount.
Here's whats working
Option Compare Database
Option Explicit
Public Sub LoadQ2()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("test")'test is the name of my table which contains 13 rows
With rs
Debug.Print .RecordCount
.Close
End With
Set db = Nothing
Set rs = Nothing
End Sub
and here's whats not working
Option Compare Database
Option Explicit
Public Sub LoadQ2()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim strSQL As String
strSQL = "SELECT test.number_id FROM test"
Set db = CurrentDb
Set rs = db.OpenRecordset(strSQL)
With rs
Debug.Print .RecordCount
.Close
End With
Set db = Nothing
Set rs = Nothing
End Sub
I should get the same result with both recordcount right?? Also I'd like to see the line I have in the recordset in the debug is it possible to print the content of the recordset in the debug window??
To print the contents of the recordset, you can do one of these two options..
debug.print rs.fields(0) & ", " & rs.fields(1)
or
debug.print rs("ColumnNameHere") & ", " & rs("AnotherColumnName")
.... found the answer
before doing the Debug.Print .RecourdCount i added .MoveLast and got the right number of recordcount
Looks like recordcount just means at what record that he is not how many records
Just to complement as you already found the answer yourself :)
The Dynaset data type (default for DAO recordset) doesn't fully populate until you go through all its records - since the need to do a .MoveLast before checking how many records it actually has.
I presume that DAO just returns 1 for the recordcount as an easy way to check beforehand if the recordset is empty or not (e.g. recordcount > 0) without having to go through the hassle of moving between records.

Code To Loop Through and Edit Recordsets

I have found how to loop through recordsets with the following link:
Code to loop through all records in MS Access
However, I want to know if it is possible if I can remove a record from the recordset if it doesn't meet criteria that I specify in the loop.
EDIT
I am now getting an error with the following code:
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("fieldHistory", dbOpenTable)
where fieldHistory is the name of the query recordset I want to open. Why am I getting this error? The last line of code there is the source of the error and Access simply states "Invalid operation"
Yes, you can use the DAO recordset's Delete method to delete the current record. This example will delete rows where the fname value is "xxx".
Public Sub DeleteRecordsetRow()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("tblDiscardMe", dbOpenTable)
Do While Not rs.EOF
If rs!fname = "xxx" Then
rs.Delete
'* the next line would trigger *'
'* error 3167: "Record is deleted." *'
''Debug.Print rs!fname
End If
rs.MoveNext
Loop
rs.Close
Set rs = Nothing
Set db = Nothing
End Sub
Notice that immediately after rs.Delete (i.e. before MoveNext), the deleted row is still "current", but you can't access its values. You can uncomment the Debug.Print line to examine this further.
Edit:
Since your record source is a query rather than a table, try this to narrow down the reason you're getting an error with OpenRecordset.
Public Sub foo20110527a()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("fieldHistory")
If Not (rs.BOF And rs.EOF) Then
rs.MoveLast
MsgBox "RecordCount: " & rs.RecordCount
Else
MsgBox "No records"
End If
rs.Close
Set rs = Nothing
Set db = Nothing
End Sub
Since you used English (rather than English-like technical terms), your intent isn't very clear. You ask if you can "...remove a record...", which can mean either that you want to Delete it (in which case you already have a good answer form HansUp), or that you want to filter it out so that you don't see it, while leaving it in the underlying database.
If your intent is the latter (filtering), you have two choices:
Use a SQL statement with a WHERE clause in the original OpenRecordset call.
Use the Recordset's .Filter property before you enter the loop.
Access comes with adequate (if not stellar) Help on either topic.
