Hi
Im new to VB not sure how to run an access query through VB6
I have a button on a form that i want to update a table in access by using a query i created in access
how easy is it to get VB to run the query at the click if the button?

maybe something like:
Private Sub btnUpdate_Click()
Dim rs As Recordset
'Dim qd As QueryDef
Dim mydb As Database


Set mydb = db.OpenRecordset("queryname")

'Set rs = db.OpenRecordset
'If rs.RecordCount > 0 Then
    'Do While Not rs.EOF
      'rs.MoveNext
    'Loop
  'End If
  'rs.Close
  'Set rs = Nothing
 
'Exit Sub


End Sub

You can substitute the "Select.... " codes of the previous examples and simply enter the Query name created in Access.  This helps if your Access query includes joins and such.  Instead of entering all this as a long SQL string in VB, you simply open the query as a recordset (just like a table).
You will still need a WHERE (perhaps) and such..... but it's easier.

however when i enter in my database name then run it, it throughs an error:
Runtime error 3078
Microsoft jet engine cannot find the input table or query
C:\DatabaseName.mdb' make sure it exists
but its there!!
this is the code:
Private Sub btnUpdate_Click()
Dim rs As Recordset
Dim mydb As Database

Set mydb = db.OpenRecordset("C:\DatabaseName") *fails here*
Set rs = db.OpenRecordset("QueryName")
If rs.RecordCount > 0 Then
'rs.Fields("yourfield") = Text1.Text
rs.Update
rs.Close
End If
Set rs = Nothing
End Sub                                            Its doing my nut in!!

Change this line:

   Set mydb = db.OpenRecordset("C:\DatabaseName") *fails here*

To:

   Set mydb = DBEngine.OpenDatabase("C:\DatabaseName")

   Private Sub btnUpdate_Click()
    Dim rA As Integer
    Dim db As New ADODB.Connection  
   
   db.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\dataBaseName.mdb"
   db.Open
   db.Execute "INSERT INTO TableA SELECT * FROM TableB", rA
    If rA > 0 Then
      MsgBox "Completed!!"
      End If
      db.Close
      Set db = Nothing
