How can I better optimize my PHP and MySQL Queries? -


i have website i'm working on , works fine. i'm concerned under load way doing things cause server lag.

in database have table lot of information in (14+ columns , several hundred entries). php page has script on generate page links (page 1 of 6, next page, previous, first, last, etc.). displays 25 entries per page. script multiplies page number 25 entry in table needs start on select.

that's not horrible don't think. real issue comes "page x of y". meaning need know how many pages of items there be, or how many times 25 goes number of entries. i've done using like:

select count(id) `footwear`

to count of entries in table. using count can calculate pages. efficient way of doing things? or perhaps there's better way calculate page count?

i might recommend query caching in mysql improve general performance.

here's guide enable that: http://www.cyberciti.biz/tips/enable-the-query-cache-in-mysql-to-improve-performance.html

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
