c# - Read CheckBox Values in ASP.Net from a SQL db? -

-

i have table of checkboxes inserted sql db '1' , '0'. however, retrieve values again load event, i'm not able them. code:

    private void getauditchecklist() {     sqlcommand cmd = null;     string conn = configurationmanager.connectionstrings["connectionstring"].connectionstring;     string querystring = @"select mount, braker, access, conn_net, log_book, pictures, floor, cb_lenght, channel auditor_checklist " +         "where site_id = @siteid";              using (sqlconnection connection =                new sqlconnection(conn))     {         sqlcommand command =             new sqlcommand(querystring, connection);         connection.open();         cmd = new sqlcommand(querystring);         cmd.connection = connection;          cmd.parameters.add(new sqlparameter("@siteid", //the name of parameter map               system.data.sqldbtype.nvarchar, //sqldbtype value               20, //the width of parameter               "site_id")); //the name of column source         //fill parameter value retrieved         //from text field         cmd.parameters["@siteid"].value = foo.site_id;          sqldatareader reader = cmd.executereader(); while (reader.read())    {                        checkbox1.checked = (reader.getboolean(reader.getordinal("mount")));    checkbox2.checked = (reader.getboolean(reader.getordinal("braker")));    checkbox3.checked = (reader.getboolean(reader.getordinal("access")));    checkbox4.checked = (reader.getboolean(reader.getordinal("conn_net")));    checkbox5.checked = (reader.getboolean(reader.getordinal("log_book")));    checkbox6.checked = (reader.getboolean(reader.getordinal("pictures")));    checkbox8.checked = (reader.getboolean(reader.getordinal("floor")));    checkbox9.checked = (reader.getboolean(reader.getordinal("cb_lenght")));    checkbox10.checked = (reader.getboolean(reader.getordinal("channel")));    }     reader.close();     }         }

what missing checkmark sql db? below how insert sql:

    private void saveauditchecklist() {     if (auditchecklist != null)     {         sqlcommand cmd = null;         string conn = configurationmanager.connectionstrings["connectionstring"].connectionstring;          string querystring = @"insert auditor_checklist values(" +             "@siteid, @mount, @braker, @access, @connnet, @logbook, @pictures, @floor, @cblenght, @channel) ";          using (sqlconnection connection =                    new sqlconnection(conn))         {             sqlcommand command =                 new sqlcommand(querystring, connection);             connection.open();             cmd = new sqlcommand(querystring);             cmd.connection = connection;             cmd.parameters.add(new sqlparameter(                 "@siteid",                        //the name of parameter map                 system.data.sqldbtype.nvarchar,   //sqldbtype value                 20,                               //the width of parameter                 "site_id"));                      //the name of column source              //fill parameter value retrieved             //from text field             cmd.parameters["@siteid"].value = foo.site_id;             cmd.parameters.add(new sqlparameter("@mount", sqldbtype.bit));             cmd.parameters["@mount"].value = checkbox1.checked;             cmd.parameters.add(new sqlparameter("@braker", sqldbtype.bit));             cmd.parameters["@braker"].value = checkbox2.checked;             cmd.parameters.add(new sqlparameter("@access", sqldbtype.bit));             cmd.parameters["@access"].value = checkbox3.checked;             cmd.parameters.add(new sqlparameter("@connnet", sqldbtype.bit));             cmd.parameters["@connnet"].value = checkbox4.checked;             cmd.parameters.add(new sqlparameter("@logbook", sqldbtype.bit));             cmd.parameters["@logbook"].value = checkbox5.checked;             cmd.parameters.add(new sqlparameter("@pictures", sqldbtype.bit));             cmd.parameters["@pictures"].value = checkbox6.checked;             cmd.parameters.add(new sqlparameter("@floor", sqldbtype.bit));             cmd.parameters["@floor"].value = checkbox8.checked;             cmd.parameters.add(new sqlparameter("@cblenght", sqldbtype.bit));             cmd.parameters["@cblenght"].value = checkbox9.checked;             cmd.parameters.add(new sqlparameter("@channel", sqldbtype.bit));             cmd.parameters["@channel"].value = checkbox10.checked;             cmd.executereader();         }     } }

booleans stored 1 or 0 in sql database, datareader conversion you. instead use: 

var mybool = reader.getboolean(i);

then assign value control's value property.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
