Non so se fa quello che vi serve, cmq ecco come utilizzo io i files excel (visti come un db)
codice:
Public Function CreateExcelOrder(ByVal userID As Integer, ByVal DataRows As Data.DataTable, ByVal BaseFilePath As String, _
ByVal FilePath As String, Optional ByVal Notes As String = "", Optional ByVal FileName As String = "", Optional ByVal Reference As String = "") As String
Dim con As OleDb.OleDbConnection
Dim cmd As OleDb.OleDbCommand
Dim SaveFilePath As String = FilePath
If FileName = "" Then
SaveFilePath = SaveFilePath & "\" & CStr(userID) & ".xls"
Else
SaveFilePath = SaveFilePath & "\" & FileName
End If
SaveFilePath = Replace(SaveFilePath, "\\", "\")
System.IO.File.Copy(BaseFilePath, SaveFilePath)
con = New OleDb.OleDbConnection
con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & SaveFilePath & ";" & _
"Extended Properties = ""Excel 8.0;HDR=YES;"""
con.Open()
cmd = New OleDb.OleDbCommand
cmd.Connection = con
cmd.CommandText = "Insert Into [Foglio1$] (Codice_Fidi, Quantità, Appunti, Riferimenti, Tipologia_acquisizione) Values ('" & DataRows.Rows(0).Item(0) & _
"', " & DataRows.Rows(0).Item(1) & ", '" & Notes & "', '" & Reference & "', '03')"
cmd.ExecuteNonQuery()
For i As Integer = 1 To DataRows.Rows.Count - 1
cmd.CommandText = "Insert Into [Foglio1$] (Codice_Fidi, Quantità) Values ('" & DataRows.Rows(i).Item(0) & _
"', " & DataRows.Rows(i).Item(1) & ")"
cmd.ExecuteNonQuery()
Next
cmd.Dispose()
cmd = Nothing
con.Dispose()
con = Nothing
Return FileName
End Function
