Test database connection, link string in Web.config ")]  public bool Conectdb ()   {  Strcon = configurationsettings.appsettings[" Sqlconduke "];  conn = new SqlConnection (Strcon);  try , { . Open ();  return true; }  catch (Exception)   {  return false; }  finally  {&nbsp ; Conn. Close (); } }    code is as follows: [WebMethod (Description = "Get detailed data (DataTable) based on <b> photo name </b>, STRTB , eg:panview;strimgname,eg:20131019072740-0000150 ")]  public DataTable getinfobyimgname (string STRTB, String Strimgname)   {  bool Ifcon = CONECTDB ();  if (Ifcon)   {  string sql_bfcar = "SELECT * FROM dbo." + STRTB + "where imagename like '%" + strimgname + "% '";  da = new SqlDataAdapter (SQL_BFCAR, conn);  myds = NE W DataSet ();nbsp Da.

Rows[0][0]);  string strlinkguid = Getinfobyimgname (STRTB, Strimgname). ROWS[0][1]. ToString ();  String sql_bfcar = "SELECT * FROM dbo." + STRTB + "where linkguid like '%" + strlinkguid + "%" ";  da = new SqlDataAdapter (SQL_BFCAR, conn);  myds = new DataSet ();  da.
