No data importing from Excel to Access with ADO - vba

Question

I have a form in Excel that writes to an Excel sheet. In the VBA below, I have requested the cells update an Access database.
There are no errors in uploading the data but when I go to my access sheet there is no data present.
Access table: (Click to enlarge)
Sub Export_Data()
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim dbPath, x As Long, i As Long, nextrow As Long
On Error GoTo errHandler: 'add error handling
'Variables for file path and last row of data
dbPath = Sheet19.Range("I3").Value
nextrow = Cells(Rows.Count, 1).End(xlUp).Row
Set cnn = New ADODB.Connection 'Initialise the collection class variable
If Sheet18.Range("A2").Value = "" Then 'Check for data
MsgBox " Add the data that you want to send to MS Access"
Exit Sub
End If
cnn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & dbPath
Set rst = New ADODB.Recordset 'assign memory to the recordset
rst.Open Source:="SELECT * FROM [ARF Data Log]", ActiveConnection:=cnn, _
CursorType:=adOpenDynamic, LockType:=adLockOptimistic
Options = adCmdOpenTable
'you now have the recordset object; add the values to it
For x = 2 To nextrow
rst.AddNew
For i = 1 To 29
rst(Cells(1, i).Value) = Cells(x, i).Value
Next i
rst.Update
Next x
rst.Close 'close the recordset
cnn.Close 'close the connection
Set rst = Nothing 'clear memory
Set cnn = Nothing
'communicate with the user
MsgBox " The data has been successfully sent to the access database"
Application.ScreenUpdating = True 'Update the sheet
Sheet19.Range("h7").Value = Sheet19.Range("h8").Value + 1 'show the next ID
Sheet18.Range("A2:ac1000").ClearContents 'Clear the data
On Error GoTo 0
Exit Sub
errHandler:
Set rst = Nothing 'clear memory
Set cnn = Nothing
MsgBox "Error " & Err.Number & " (" & Err.Description & ") in Export_Data"
End Sub

You need to specify the fields you are updating. This is either done with ! or with .Fields. If you do not specify, you could use the index of the column.
- With !
Sub DataPopulation()
Dim myConn As New ADODB.Connection
Dim DBS As ADODB.Recordset
Set myConn = CurrentProject.Connection
Set DBS = New ADODB.Recordset
DBS.Open "SomeDB", myConn, adOpenKeyset, adLockOptimistic
DBS.AddNew
DBS!StudentNumber = 1
DBS!StudentName = "SomeName"
DBS!Grade = 10
DBS.AddNew
DBS!StudentNumber = 2
DBS!StudentName = "SomeFamilyName"
DBS!Grade = 10
DBS.Update
DBS.Close
Set DBS = Nothing
Set myConn = Nothing
End Sub
- With .Fields:
Do While Len(Range("A" & r).Formula) > 0
With rs
.AddNew
.Fields("Commodity #") = Range("A" & r).Value
.Update
End With
r = r + 1
Loop
- With Index: If you use the numerical index of the fields, then they start from 1 to the count of the fields. In your case rst(i) should be ok, if you have at least i columns. In the example below, there are 3 columns available:
For tblRow = 1 To 10
DBS.AddNew
For tblCol = 1 To 3
DBS(tblCol) = "Row: " & tblRow & " Col: " & tblCol
Next
