The checking is always true after first loop in VBA in Access - vba

The "Check" somehow is always 0 after first loop, I keep debugging but still cannot find out why. Any idea? The data suppose to make "check" be 0 sometimes but not all the time.
Private Sub Command12_Click()
Dim db As Database
Dim rs As DAO.Recordset
Dim rs2 As DAO.Recordset
Set db = CurrentDb()
Set rs = db.OpenRecordset("Amity")
Set rs2 = db.OpenRecordset("Opportunity")
Set rs3 = db.OpenRecordset("SalesForceDonor")
Set rs4 = db.OpenRecordset("Donor")
While Not rs.EOF
check = 0
While Not rs3.EOF
If rs("Donor_Code") = rs3("Donor_Code") Then
check = 1
End If
rs3.MoveNext
Wend
If check = 0 Then
rs4.AddNew
rs4![Donor_Code] = rs![Donor_Code]
rs4.Update
End If
rs2.AddNew
rs2![Donor_Code] = rs![Donor_Code]
rs2![Donation_name] = rs![Donation_name]
rs2.Update
rs.MoveNext
Wend
rs3.Close
rs4.Close
rs2.Close
rs.Close
End Sub


I've found somethig that must be corrected, adding rs3.MoveFirst for each record of rs:
Private Sub Command12_Click()
Dim check
Dim db As Database
Dim rs As DAO.Recordset
Dim rs2 As DAO.Recordset
Set db = CurrentDb()
Set rs = db.OpenRecordset("Amity")
Set rs2 = db.OpenRecordset("Opportunity")
Set rs3 = db.OpenRecordset("SalesForceDonor")
Set rs4 = db.OpenRecordset("Donor")
While Not rs.EOF
check = 0
rs3.MoveFirst ' <= here we move to the first record of rs3!!!
Do While Not rs3.EOF
If rs("Donor_Code") = rs3("Donor_Code") Then
check = 1
Exit Do
End If
rs3.MoveNext
Loop
If check = 0 Then
rs4.AddNew
rs4![Donor_Code] = rs![Donor_Code]
rs4.Update
End If
rs2.AddNew
rs2![Donor_Code] = rs![Donor_Code]
rs2![Donation_name] = rs![Donation_name]
rs2.Update
rs.MoveNext
Wend
rs3.Close
rs4.Close
rs2.Close
rs.Close
End Sub

Deleting from recordset

I have a sub that deletes the records in recordset2 based on the records of recordset1.
The function works but very slow. Recordset1 has 300 records, Recordset2 73000 records.
Is there any way to speed this up?
Is it possible to use a filter, or a refiltered recordset?
Public Sub Erase()
DoCmd.SetWarnings False
Dim db As DAO.Database
Dim rs1 As DAO.Recordset
Dim rs2 As DAO.Recordset
Set db = CurrentDb()
Set rs1 = db.OpenRecordset("Tbl_1", dbOpenTable)2
Set rs2 = db.OpenRecordset("KISS_2", dbOpenDynaset)2
If rs1.RecordCount > 0 Then
rs1.MoveLast
rs1.MoveFirst
lngCountRecordsRs1 = rs1.RecordCount
Do Until rs1.EOF
rs2.MoveFirst
Do Until rs2.EOF
If rs1!ID = rs2!ID Then
With rs2
.Delete
End With
End If
rs2.MoveNext
Loop
rs1.MoveNext
Loop
End If
rs2.Close
rs1.Close
Set rs2 = Nothing
Set rs1 = Nothing
Set db = Nothing
Errorhandler:
End Sub

Eventually I solved the problem with .FindFirst.
Thanks for the input!
With rs2
.FindFirst "Id = " & rs1![ID]
If rs2.NoMatch Then
Else
.Delete
Exit Do
End If
End With

MS Access VBA to update a Combobox table field

I have a table with a field with the display control set to Combo Box and I have not been able to read or write to it using an OpenRecordSet. What would I have to do to modify to get these scenarios to work?
Sub TryToRead()
Set db = CurrentDb
Set rs = db.OpenRecordset("tbl", dbOpenDynaset)
x = rs!FieldName '<------Combo Box Field. x shows no info.
End Sub
Sub TryToWrite()
Set db = CurrentDb
Set rs = db.OpenRecordset("tbl", dbOpenDynaset)
With rs
.AddNew
rs!FieldName = "Test Value" '<------ Results in Run-time error 64224 Application-defined or object-defined error
.Update
End With
End Sub

I think I have what I need.
Sub Testing()
Set db = CurrentDb
Set rs = db.OpenRecordset("tbl", dbOpenDynaset)
MyStr = Array("Value1", "Value2")
Do Until rs.EOF = True
Set rs2 = rs!FieldName!Value
rs.Edit
For Each c In MyStr
rs2.AddNew
rs2!Value.Value = c
rs2.Update
Next c
rs.Update
rs.MoveNext
Loop
End Sub

How do you copy the entire record from one table to another including attachment filed?

I have two tables, tb1 and tb2. I would like to copy the entire record from tab1 to tbl2. The tables contain attachment fields so INSERT statement is not suitable. My current approach uses DAO but its only copying the first record. Please see code:
Private Sub InsertRecord_Click()
Dim db As Database
Dim rs1 As DAO.Recordset
Dim rs2 As DAO.Recordset
Dim rsAttachment1 As DAO.Recordset2
Dim rsAttachment2 As DAO.Recordset2
Set rs1 = CurrentDb.OpenRecordset("tbl1")
Set rs2 = CurrentDb.OpenRecordset("tbl2")
With rs1
rs2.AddNew
rs2.Fields("ItemNo").Value = rs1.Fields("ItemNo").Value
rs2.Fields("Location").Value = rs1.Fields("Location").Value
rs2.Fields("Owner").Value = rs1.Fields("Owner").Value
rs2.Fields("DateSent").Value = DateTime.Now
Set rsAttachment1 = rs1.Fields("ItemImage").Value
Set rsAttachment2 = rs2.Fields("ItemImage").Value
With rsAttachment1
Do While Not .EOF
rsAttachment2.AddNew
rsAttachment2.Fields("FileData") = .Fields("FileData")
rsAttachment2.Fields("FileName") = .Fields("FileName")
rsAttachment2.Update
rsAttachment1.MoveNext
Loop
End With
rs2.Update
.MoveNext
End With
rs2.Close
Set rs2 = Nothing
'rsAttachment1.Close
Set rsAttachment1 = Nothing
Set rsAttachment2 = Nothing
End Sub
Any other better approach is also welcome.

Use a loop:
While Not rs1.EOF
With rs1
rs2.AddNew
rs2.Fields("ItemNo").Value = rs1.Fields("ItemNo").Value
rs2.Fields("Location").Value = rs1.Fields("Location").Value
rs2.Fields("Owner").Value = rs1.Fields("Owner").Value
rs2.Fields("DateSent").Value = DateTime.Now
Set rsAttachment1 = rs1.Fields("ItemImage").Value
Set rsAttachment2 = rs2.Fields("ItemImage").Value
With rsAttachment1
Do While Not .EOF
rsAttachment2.AddNew
rsAttachment2.Fields("FileData") = .Fields("FileData")
rsAttachment2.Fields("FileName") = .Fields("FileName")
rsAttachment2.Update
rsAttachment1.MoveNext
Loop
End With
rs2.Update
.MoveNext
End With
rs1.MoveNext
Wend

VBA Access IF condition

I have a problem that my IF somehow doesn't validate good value of the field on index 0.
Here is the UDPATED code:
Private Sub Parametri()
Dim db As dao.Database
Dim rs As dao.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("ribe")
rs.MoveLast
rs.MoveFirst
For i = 0 To rs.RecordCount
If rs.Fields(i).Value > 2 Then
Debug.Print rs.Fields("Lokacija_GS")
rs.MoveNext
End If
Next
End Sub
And here is the result:
1
43.626145
43.626145
43.630122
43.632358
43.625833
This value of "1" on index 0 should be skipped... but it isnt?
here is the table:
So for example if some row is 0 or 1 or NULL I want to skip it...

Here is the correct code,
Private Sub Parametri()
Dim db As dao.Database
Dim rs As dao.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("ribe")
rs.MoveLast
rs.MoveFirst
Do While Not rs.EOF
If rs.Fields("Lokacija_GS").Value > 2 Then _
Debug.Print rs.Fields("Lokacija_GS")
rs.MoveNext
Loop
Set rs = Nothing
Set db = Nothing
End Sub

Copy a row from a table to another table in Access

This is my first time working with Access so I am kind of confused now. Here is my code and I don't know which part is wrong. There isn't error but there isn't anything happening after I click the button. Thanks! Here is the code:
Private Sub Command12_Click()
Dim db As Database
Dim rs As DAO.Recordset
Dim rs2 As DAO.Recordset
Set db = CurrentDb()
Set rs = db.OpenRecordset("Amity")
Set rs2 = db.OpenRecordset("Opportunity")
With rs2
.AddNew
.Fields("Donor_Code") = rs!Donor_Code
.Update
.Close
End With
rs.Close
End Sub

You can try this with a Do loop:
Private Sub Command12_Click()
Dim db As Database
Dim rs As DAO.Recordset
Dim rs2 As DAO.Recordset
Set db = CurrentDb()
Set rs = db.OpenRecordset("Amity")
Set rs2 = db.OpenRecordset("Opportunity")
Do While (Not rs.EOF)
rs2.AddNew
rs2.Fields("Donor_Code").Value = rs!Donor_Code.Value
rs2.Update
rs.MoveNext
Loop
'
rs2.Close
Set rs2 = Nothing
rs.Close
Set rs = Nothing
Set db = Nothing
'
End Sub
