-

i using following code select 1 database , need insert database.. please suggest me code:

code :

'connection original database have import  dim constrorg string = "provider=microsoft.ace.oledb.12.0;data source=" + strpath dim conn_orgdb new oledb.oledbconnection(constrorg)  'connection database have import  dim app_path = system.appdomain.currentdomain.basedirectory() dim constr string = "provider=microsoft.ace.oledb.12.0;data source=" + app_path + "mydb.accdb"  dim cnnoledb new oledb.oledbconnection(constr)      dim strselinv_one string = ("select * inv_one (docu_dt>=@stdt , docu<=@enddt) ")     dim comm_inv_one oledb.oledbcommand = new oledb.oledbcommand(strselinv_one, conn_orgdb )      comm_inv_one.parameters.addwithvalue("@stdt", sttime)     comm_inv_one.parameters.addwithvalue("@enddt", endtime)      dr = comm_inv_one.executereader      while dr.read = true      dim strinsinv1 string = "insert invoice_one(code_no,lay,..) select code_no,lay,... inv_one (code_no=@code)"         dim comm_insinv1 oledb.oledbcommand = new oledb.oledbcommand(strinsinv1, cnnoledb)          comm_insinv1.parameters.addwithvalue("@code", code_no)        comm_insinv1.executenonquery()        loop          'here invoice_one table belongs cnnoledb connection obj of 1 database , inv_one table belongs conn_orgdb  connection object of database..       ' how use 2 connection object ? if use 1 connection object i.e. cnnoledb gives following error:      " microsoft office access database engine cannot find input table or query 'inv_one'.  make sure exists , name spelled correctly.     "

please suggest me code.. thank you

try code, don't make long ( wack out stuff don't need , imput code, ....

in addition : 

dim connectionstr = constants.input.mdb.connection_string & _     "data source=" & dbfullpath & ";" dim connection new system.data.oledb.oledbconnection(connectionstr)

in addition use 

dim connectionstr2 = "other conection string" dim connection2 new system.data.oledb.oledbconnection(connectionstr)

and import code.

link: selecting data in ms access vb.net slow. doing right?

i sorry if won't help, since don't have access db cannot further test this. reguards.

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...
