1.	Create a text file called textfile.txt that contains code similar to the following: "F1","F2","F3" "one", "two", "three" "1a","2b", "3c" 1,2,3
2.	Create a new Standard EXE in Visual Basic. Form1 is created by default.
3.	On the Project menu, click to select References, and then select Microsoft Active Data Objects and Microsoft ADO Ext.2.x for DDL and Security.
4.	Add two CommandButton controls to the form, and name them CmdOpen and CmdInsert.
5.	Add the following code to the form. You need to change the paths to reflect locations on your machine. Dim cn As New ADODB.Connection Dim rs As New ADODB.Recordset Dim PathtoTextFile As String Dim PathtoMDB As String Dim myarray() As Variant Private Sub Form_Load() PathtoTextFile = "C:\PathtoTextFile\" PathtoMDB = "C:\PathtoMDB\" CmdOpen.Caption = "Open textfile and display field value" CmdInsert.Caption = "Insert textfile values into MDB" End Sub Private Sub CmdOpen_Click() '============================method 1================================= cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=" & PathtoTextFile & ";" & _ "Extended Properties=""text;HDR=YES;FMT=Delimited""" rs.Open "select * from TextFile.txt", _ cn, adOpenStatic, adLockReadOnly, adCmdText '============================method 2================================= 'cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=" & PathtoMDB & "Northwind.mdb" 'rs.Open "SELECT * FROM [Text;Database=" & PathtoTextFile & ";" & _ "HDR=YES;FMT=Delimited].[textfile.txt]", _ cn, adOpenStatic, adLockReadOnly, adCmdText '===================================================================== MsgBox rs(0) rs.Close cn.Close End Sub Private Sub CmdInsert_Click() Set Cat = New ADOX.Catalog Set objTable = New ADOX.Table cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=" & PathtoMDB & "Northwind.mdb" 'Open the Catalog Set Cat.ActiveConnection = cn 'delete the table if it exists On Error Resume Next Cat.Tables.Delete "table1" 'Create the table objTable.Name = "Table1" 'Create and Append a new fields to the "table1" Columns Collection objTable.Columns.Append "F1", adWChar objTable.Columns.Append "F2", adWChar objTable.Columns.Append "F3", adWChar Cat.Tables.Append objTable 'Insert into table1 the contents of textfile.txt cn.Execute "INSERT INTO Table1 SELECT * FROM " & _ "[Text;Database=" & PathtoTextFile & ";HDR=YES].[TextFile.txt]" cn.Close MsgBox "Finished Inserting into MDB" End Sub
