Uploading Excel File into MS Access using vb.net - vb.net

Question

I am trying to import an Excel file into an Access DB via vb.net
the idea is the customer can export the data into excel, modify it, add, delete them importing it back.
The data exported has exactly the same format than the table to import to.
I am using the code below:
Try
Dim strFileName As String = String.Empty
Dim XLda As New OleDbDataAdapter
Dim ExcelTables As New DataTable
Dim StrSelect = "SELECT * FROM [{0}]"
OpenFileDialog1.FileName = ""
OpenFileDialog1.InitialDirectory = mdlGlobalStuff.sMasterDataPath
OpenFileDialog1.Filter = "Excel|*.xls|All files (*.*)|*.*"
If OpenFileDialog1.ShowDialog() <> Windows.Forms.DialogResult.OK Then
Exit Sub
End If
strFileName = OpenFileDialog1.FileName
Dim MyXLConnection As New OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & strFileName & ";Extended Properties=Excel 8.0;")
Using MyXLConnection
Using cmd As New OleDbCommand
cmd.Connection = MyXLConnection
cmd.CommandText = "INSERT INTO [MS Access;Database=InvoicingToolDB.accdb].[tbl_Bases] SELECT * FROM [Sheet1$]"
If MyXLConnection.State = ConnectionState.Open Then
MyXLConnection.Close()
End If
MyXLConnection.Open()
cmd.ExecuteNonQuery()
End Using
End Using
Catch ex As Exception
MsgBox("ImportLinkLabel_LinkClicked: Importing Base data" & vbCrLf & ErrorToString())
End Try
I always have an error message saying:
Unrecognized database format 'c:\--path to db--\InvoicingToolDB.accdb'
The path is correct and I don't understand why the format wouldn't be recognized.

Answer 1

Ok I have found the issue. The OLEDB Provider version was not the right one (4.0 is not reading Access .accdb format but old .mdb format only)
Replacing:
Dim MyXLConnection As New OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & strFileName & ";Extended Properties=Excel 8.0;")
With:
Dim MyXLConnection As New leDbConnection("provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & strFileName & ";Extended Properties=Excel 8.0;")
Works perfectly.
