my question simple: how translate c code : if (x == y + 1) // code else if (x == y - 1) // code else if (x == y + 2) .... basically thinking of using pattern matching seemed appropriate. unfortunatly pattern doesn't work: match x | y + 1 -> code | y - 1 -> code | y + 2 -> code | _ -> code the compiler doesn't seem happy , have found out, expressions on pattenr matching did not tolerated. therefore tried putting them in values thusly: let v1 = y + 1 in let v2 = y - 1 in let v3 = y + 2 in match x | v1 -> code | v2 -> code | v3 -> code | _ -> code unfortunatly warnings saying values v1 v2 , v3 unused , the match cases use them unused too. how can match expression other expressions? thanks actually, c code valid ocaml code. if x = y + 1 (* code *) else if x = y - 1 (* code *) else if x = y + 2 .... pattern matching not replacement if then , has completly different purpose. ocaml allows construct types such type ...

i cant toggleclass work, here's jsfiddle: http://jsfiddle.net/edddotcom/v6vhx/ clicking on image supposed make text change colour removing .mid class not doing @ moment. here's javascript: $(document).ready(function(){ $("#image").click(function(){ $("p").toggleclass(".mid"); }); }); and html <div class="container"> <div class="row"> <p>hello</p> <p class="mid">hello</p> <img id="image" src="http://icons.iconarchive.com/icons/artua/mac/512/earth-icon.png"/> </div> </div> the css saying .mid class red text, if need see jsfiddle, what missing/doing wrong? with toggleclass, leading dot before class name not required. $("p").toggleclass("mid");

i taking scala course on coursera on free time after work, in attempt give try functional programming. working on assignment supposed "calculate" union of 2 sets contain object. intentionally omitting details it's not important trying ask here. relevant, however, sets defined binary trees, each node containing element, , 2 subtrees. that being case; example union in lecture follows: def union(other:btset) :btset = ((left union right) union other) incl element question1: quite frankly, after having read relevant faq , other forum threads, still don't understand how , why function works. there absolutely no "action" done here in union implementation besides adding (the incl call) element @ head node, calls on , on again. appreciative of explanation... question2: course forum contains many posts stating solution not efficient @ all, , not enough. seeing don't understand how works begin don't understand why it's not enough. please n...

if {field_a} = 0 0 else (({field_b} / {field_a})*100) i trying convert formula ssrs expression. have tried many different =iff statements, cannot seem run correctly. almost duplicate question: if search here #error ssrs iif you'll plenty of results, such does iif function compute both paths in ssrs or short-circuited? rewriting statement straightforward then: =iif( fields!field_a.value = 0, 0, fields!field_b.value / iif( fields!field_a.value = 0, 1, fields!field_a.value) * 100 )

i'm dealing old structure , bad design database loose , complicated. sadly, have it. :( the old method used php query each info table. re-coded join. big problem occured. takes minute query these info (sometimes more). here's code: select *, car_db.id cid, tbl_province.province_name prov_name, config_car_color.color_title clr_title, config_car_color.description clr_desc, car_viewer.vwr_id viewers car_db inner join tbl_province on tbl_province.province_code=car_db.prov inner join config_car_color on config_car_color.id=car_db.color inner join car_viewer on car_viewer.vwr_cid=car_db.id car_db.tid='$_tid' from latest query of code took 3.37 secs. takes @ least 30 secs run code. the question please suggest me best way process these lines faster. create following indexes: car_db (tid) tbl_province (province_code) -- might pk config_car_color (id) -- might pk car_viewer (vwr_cid)
