   Set Target = Sheets("Sheet1").Range("A1")
   Set cn = CreateObject("ADODB.Connection")
   cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & DBFullName & ";"

   Set rs = CreateObject("ADODB.Recordset")
   rs.Open "SELECT * FROM test", cn, , , adCmdText

  For int i = 0 To rs.Fields.Count - 1
  Target.Offset(1, i).Value = rs.Fields(i).Name
  Next
  Target.Offset(1, 0).CopyFromRecordset rs
  rs.Close
  Set rs = Nothing
  cn.Close
  Set cn = Nothing

PLease help me to resolve the error

Answer 1

I've tried using below connection string and it throws runtime error '438'

Run-time error: '438' means that the Object doesn't support this property or method..

You are getting that error because you are mixing VB.Net with VBA

This

For int i = 0 To rs.Fields.Count - 1

should be

For i = 0 To rs.Fields.Count - 1

Beside the above, I guess DBFullName = "D:\\Tool_Database\\Tool_Database.mdb" is a typo from your end as you are using .Accdb ?

This should do it for you. Drop the WHERE clause if you don't want to apply a filter.

Also, set a reference to: Microsoft ActiveX Data Objects 2.8 Library

Sub Select_From_Access()
    Dim cn As Object, rs As Object
    Dim intColIndex As Integer
    Dim DBFullName As String
    Dim TargetRange As Range

    DBFullName = "C:\Users\Ryan\Desktop\Nwind_Sample.mdb"

    'On Error GoTo Whoa

    Application.ScreenUpdating = False

    Set TargetRange = Sheets("Select").Range("A1")

    Set cn = CreateObject("ADODB.Connection")
    cn.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & DBFullName & ";"

    Set rs = CreateObject("ADODB.Recordset")
    rs.Open "SELECT * FROM [OrderDetails] WHERE [OrderID] = 10248", cn, , , adCmdText

    ' Write the field names
    For intColIndex = 0 To rs.Fields.Count - 1
    TargetRange.Offset(1, intColIndex).Value = rs.Fields(intColIndex).Name
    Next

    ' Write recordset
    TargetRange.Offset(1, 0).CopyFromRecordset rs

    Application.ScreenUpdating = True
    On Error Resume Next
    rs.Close
    Set rs = Nothing
    cn.Close
    Set cn = Nothing
    On Error GoTo 0
    Exit Sub

End Sub
