i have table of structure:- row1:- not inside details group. row 2:- dynamically populating row. sequence as:- a x a1 1 a2 2 b y b1 30 b2 40 i need calculate value of y(which value of b1+b2) , x(which value of a1+a2) also in row 1 need display x+y. please note:- not sure number of rows can there in either or b. y can b1+b2+b3.... on. also , b being populated same dataset. it's bit unclear how data set can't give answer summing based on condition you'd want like: =sum(iif(fields!a.value = "x", fields!unknown?.value, 0)) this sum of unknown field when field a = x . if isn't looking for, try adding field names , relate them values.

during work saw following code snippet , wonder, if there reason casting "case-values" larger datatype. guess, used offer possibility of having more 256 different states later on, then, state variable must larger. here code talking about: #define state_1 (uint8_t)(0x00) #define state_2 (uint8_t)(0x01) ... #define state_n (uint8_t)(0x..) void handlestate(uint8_t state) { switch(state) { case (uint16_t)state_1: // handle state 1 break; case (uint16_t)state_2: // handle state 2 break; ... case (uint16_t)state_n: // handle state n break; default: break; } } is there reason this? it looks failed attempt rid of implicit integer promotions on 8-bit or 16-bit microcontroller. first of all, there no way integer promotion can cause harm here, preventing overly pedantic , reduces readability. @ glance looks nonsense. but. perhaps coding standard used enforced no implicit conversions allowed?

as part of test suite measuring fps web application need perform smooth scroll of web page. is, same smoothness when user grabs scroll bar , moves mouse. so far have tried using simulating key presses sikuli, i.e. pressing arrow up/down keys multiple times scroll whole page. have tried using javascript approach: public void scrollsmooth(int durationofscroll){ long timewhenstarting = system.currenttimemillis() / 1000l; while (system.currenttimemillis() / 1000l - timewhenstarting < durationofscroll) { ((javascriptexecutor) driver).executescript("window.scrollby(0,10)", ""); } } both these approaches fails fulfill purpose, both generate step-by-step scroll, not suitable when simultaneously want measure fps (e.g. smoothnes of page when scrolling). the solution lot more simple expected. instead of using time-based condition loop tried following: public void scrollsmooth(){ for(int i=0;i<6000;i++) { ((javascriptexecutor)

if have mongodb sharded cluster multiple mongos instances, objectid in _id consistant whichever mongos write to? for example, if write data mongos#1 , _id ascends normally, if write using mongos#2 these _id's ascend in line other writes? seeing part of objectid based on machine hash , process id, can't see sorting on objectid useless. correct? whats recomendation here? how objectid generated give fair idea query. if type in mongo console, new objectid() you see objectid sample value as objectid("558bf61f9f49f303f72dd59b") now, lets break , see how mongo generates this. 558bf61f 9f49f3 03f7 2dd59b here first 8 characters (4 bytes) represents number of seconds (not milliseconds) timestamp. the next 3 bytes machine identifies. the next 2 bytes process id. and lastly 3-bytes random value. http://api.mongodb.org/libbson/current/bson_oid_t.html so, sure mongos connected with, time goes on in ascending order (because of first p

i'm trying implement standard universal styling of text fields based strictly on login/sign fields. so, designed them identical, think i'm reusing lot of code can condensed , maybe used in variable? i'm not sure how so. the way works, i'm sure can done better this. i'm there's way minimize code better practice. i'm still learning, want learn better practice in dev. here's example of sign view & styling of fields: class joinvc: uiviewcontroller, uitextfielddelegate {` @iboutlet weak var enteremailtextfield: uitextfield! @iboutlet weak var enterpasswordtextfield: uitextfield! @iboutlet weak var enternametextfield: uitextfield! override func viewdidload() { super.viewdidload() // field border corner + width self.enteremailtextfield.layer.cornerradius = 24.0 self.enteremailtextfield.layer.borderwidth = 1.5 self.enterpasswordtextfield.layer.cornerradius = 24.0 self.enterpassw
