php - mysql query to excel -


community,

i working on report builder. objective of report builder send out email excel document weekly information coming sql table. activated when first person logs in day on monday. if monday holiday, , no 1 logs in day, timestamp not made in database. when user logs in tuesday, looks @ last timestamp see if 1 placed previous day. if not, fire on tuesday.

the first step in process looks this...

$today = cal_to_jd(cal_gregorian,date("m"),date("d"),date("y")); $yesterday = date('y-m-d', strtotime($date .' -1 day')); $holiday = false; if(jddayofweek($today,1) == 'tuesday') {     if(mysql_num_rows(mysql_query("select report_date report_builder report_date = '{$yesterday}'")) == 0)     {         $holiday = true;     } } if(jddayofweek($today,1) == 'monday' || $holiday === true) {     $today = mysql_query("select report_date report_builder report_date = curdate()");     if(mysql_num_rows($today) == 0)     {         $date = date('y-m-d h:i:s',time()-(7*86400));         mysql_query("insert report_builder (report_date) values (curdate())");

//more code here

**the question particular post follows:

is possible send information csv file not open user can see, instead saved temporary file? can done in way doesn't send background html?**

once accomplished, wanted send file user using current code looks this...

require("class.phpmailer.php"); $mail = new phpmailer(); $mail->from = "**********"; $mail->addaddress("*************"); $mail->subject = "test"; $mail->body = "hi"; $filename = $_files['file']['name']; $tmpname = $_files['file']['tmp_name']; $filename = addslashes($filename); echo $filename; $mail->addattachment("temporary file path"); if(!$mail->send()) {     echo 'message not sent.';     echo 'mailer error:'.$mail->errorinfo; }

yes can write files disk , save in number of ways. point might quick way save steps (i.e. not have create file in php) if application server , mysql on same physical host. of course assuming csv file suitable (i.e. don't need use php excel library build xls or xlsx file)

select [fields] outfile '/path/to/file' fields terminated ',' optionally enclosed '"' lines terminated '\n' your_table;

this directly create csv @ location path/to/file on machine can sent via php. please note file name must not existing file name approach not allow overwrite existing file.

if mysql host remote or need manipualte data before writing file, suggest looking @ fputcsv() (http://php.net/manual/en/function.fputcsv.php) in order write data query directly file in csv format.

$file = fopen('/path/to/file.csv', 'w');  while ($row = [your database fetch here]) {     fputcsv($file, $row); }

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
