codice:
string sql = "SELECT * FROM tbl WHERE id= " + Request.QueryString["id"];
string fotpic = Access.visRecord4(sql).DefaultView[0]["fotopiccola"].ToString();
Classe Access
codice:
public static DataTable visRecord4 (string SQL)
{
SqlConnection conn = new SqlConnection(connString);
SqlDataAdapter da = new SqlDataAdapter(SQL, connString);
DataTable myTable = new DataTable();
da.Fill(myTable);
return myTable;
}
L'errore me lo da qui (string fotpic = Access.visRecord4(sql).DefaultView[0]["fotopiccola"].ToString()
Il valore id riusltato so con certezza che sarebbe una stringa tipo pippo.jpg pluto.jpg ecc...
