i using asp.net 4.0 , mvc 2.0 web application. project requiremrnt have use server side control in application not possibl in noraml case. ideally want use adrotator control , datalist control. i saw few samples , references in codepleax mvc controllib howwver found less useful. can tell how utilize theese controls in asp.net application along mvc. note: please provide functionalities related adrotator , datalist controls not equivalent functionalities thanks in advace. mvc pages not use normal .net solution makes use of normal .net components impossible. a normal .net page use event driven solution call different methods service side mvc use actions , view completly different way handle things. also, mvc not use viewstate normal .net controlls require. found article discussing mixing of normal .net , mvc.

frequency analysis - FFT pitch detection for guitar string -

-

i have pitch detection. input (microphone) data passed fft routine, i'm looking pitch maximum value means: 

max(pow(data[i].getre(), 2) + pow(data[i].getim(), 2)) 0<= < samplessize

i need detection of guitar string's primary frequency. works freq 440 hz (and maybe higher, didn't check that) downto 250 hz. below value detected frequency twice high should be, ie. 195 hz detected frequency 380 hz. looks detects higher harmonics below 250 hz. pure 195 hz tone detects perfectly, quitar string wrong.

any suggestion can cause ? or should use more sophisticated pitch detection?

ps. sampling rate: 8000hz, input data size: 1024

i don't know guitars specifically, missing fundamentals seem quite common in acoustics. wikipedia page on pitch detection alludes secondary processing steps after fft, perhaps 1 of these helpful.

also, see these 2 questions, lots of information there: (1), (2).

mysql - Why there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT clause? -

why there can 1 timestamp column current_timestamp in default or on update clause? create table `foo` ( `productid` int(10) unsigned not null, `addeddate` timestamp not null default current_timestamp, `updateddate` timestamp not null default current_timestamp on update current_timestamp ) engine=innodb; the error results: error code : 1293 incorrect table definition; there can 1 timestamp column current_timestamp in default or on update clause this limitation, due historical, code legacy reasons, has been lifted in recent versions of mysql: changes in mysql 5.6.5 (2012-04-10, milestone 8) previously, @ 1 timestamp column per table automatically initialized or updated current date , time. restriction has been lifted. timestamp column definition can have combination of default current_timestamp , on update current_timestamp clauses. in addition, these clauses can used datetime column definitions. more information, see automati...
