.net - Adding a row to a dataset is not updating the database (C#) -

-

a simple, yet frustrating issue. i've bound datagrid local database play around , teach myself datasets , c#. binding data, no problem. custom fills (and sql selects), no problem. next comes adding record. so, add in following code:

private void badd_click(object sender, eventargs e)         {             datarow newrow = abbtestdataset.tables["main"].newrow();             newrow["name"] = "simon";             newrow["age"] = 23;             abbtestdataset.tables["main"].rows.add(newrow);         }

the datagrid updates no problem, data never committed database. i've searched high , low solution or may missing out on , nothing; @ least i've seen i'm doing right.

so missing? undoubtedly stupid.

i believe need use dataadapter send updated dataset database.

the relevant sample first link is:

    string connectionstring ="server=(local)\\sqlexpress;database=mydatabase;integrated security=sspi;";     sqlconnection conn = new sqlconnection(connectionstring);      conn.open();      sqldataadapter adapter = new sqldataadapter("select * employee order id", conn);      sqlcommandbuilder builder = new sqlcommandbuilder(adapter);      // create dataset object     dataset ds = new dataset("employeeset");     adapter.fill(ds, "employee");      // create data table object , add new row     datatable employeetable = ds.tables["employee"];     datarow row = employeetable.newrow();     row["firstname"] = "r";     row["lastname"] = "d";     row["id"] = "10";     employeetable.rows.add(row);      // update data adapter     adapter.update(ds, "employee");

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
