i'm trying create report on ms access. query originating report following: select t1.[order], t1.[hours], t1.[hours]/(select count(*) t2 t2 cstr(t1.[order]) = cstr(t2.[order])) espr1 t1; an example of data tables are: t1.[order] | t1.[hours] 1 | 100 1 | 100 2 | 300 2 | 300 2 | 300 t2.[order] | t2.[hours] 1 | 100 1 | 100 2 | 300 2 | 300 2 | 300 t1.[order] , t1.[hours] integer types. t2.[order] , t2.[hours] string types (please, don't ask!) the query executed correctly. creates additional column espr1 containing partition of t1.hours (or t2.hours) depending on count of lines having same order value. for example: [order] | [hours] | [espr1] 1 | 100 | 50 1 | 100 | 50 2 | 300 | 100 2 | 300 | 100 2 | 300 | 100 but when create text box in report the following source: = dsum([espr1]) ms access give me the error 3612 , not declares group clausole! someone of you, experienced programmers have

i have large live database. best practices making schema (doctrine) changes? when doing development can build-all , reload fixtures , fine if data structure changes can manually adjust fixtures reload correctly. how do large live database thousands of records? if pull changes prod server , data dump rebuild , reload schema changes prevent data reloading (especially if have removed column). there standard way of handling sort of thing? i find table row ordering not preserved when reloading way. look doctrine migrations, made for. can't specifics, i'm propel guy.

i have quick performance question: quicker , efficient on memory use static singleton database reference or reopen every time need access something? thanks help, ~aedon in android databases aren't kept in memory keeping reference light on memory, use file locks. using singleton first choice, however, if you're using in service or single activity, doesn't need static. if you're database instance keeps reference context, means avoid making static because source of memory leaks.

im trying automatically run script using cygwin via cmd. created bat file goes directory , executes .sh file. sh files accosiated cygwin, , tried "cygwin update.sh" in command line. open cygwin. want cygwin automatically run script file. there easy way this, i've been trying find can't. thank you! you'll want call shell script particular shell, e.g. bash. when having cygwin open, call which bash figure out binary located. cygwin comes tools can convert paths between cygwin , win32 form, pretty helpful in cases yours. there 1 other thing may work, depending on setup. there environment variable named pathext declares file extensions deemed "executable" cmd. can used advantage, if windows configured shell's "open" verb executes correct shell file extension .sh (in case). good luck.

how add or edit listview item double clicking on it? two things. first, have create list view control lvs_editlabels style, shown in using list-view controls . then, when want edit label, send lvm_editlabel message focused label. be sure handle lvn_endlabeledit message in parent.

i love git blame command, useful tracking down people don't own writing code. :-) however, possible see edited specific line before commit reported git blame , e.g. history of commits given line? for example, run following (on superb uncrustify project): $ git blame -l10,+1 src/options.cpp ^fe25b6d (ben gardner 2009-10-17 13:13:55 -0500 10) #include "prototypes.h" how can find out edited line before commit fe25b6d ? , edited before that commit? sure possible, git-fu weak. git blame -l10,+1 fe25b6d^ -- src/options.cpp you can specify revision git blame starting (instead of default of head ); fe25b6d^ parent of fe25b6d .

the following code float x = 3.141592653589793238; double z = 3.141592653589793238; printf("x=%f\n", x); printf("z=%f\n", z); printf("x=%20.18f\n", x); printf("z=%20.18f\n", z); will give output x=3.141593 z=3.141593 x=3.141592741012573242 z=3.141592653589793116 where on third line of output 741012573242 garbage , on fourth line 116 garbage. doubles have 16 significant figures while floats have 7 significant figures? why don't doubles have 14 significant figures? floating point numbers in c use ieee 754 encoding. this type of encoding uses sign, significand, , exponent. because of encoding, many numbers have small changes allow them stored. also, number of significant digits can change since binary representation, not decimal one. single precision (float) gives 23 bits of significand, 8 bits of exponent, , 1 sign bit. double precision (double) gives 52 bits of significand, 11 bits of exponent, ,

how should argmax implemented in python? should efficient possible, should work iterables. three ways implemented: given iterable of pairs return key corresponding greatest value given iterable of values return index of greatest value given iterable of keys , function f , return key largest f(key) i modified best solution found: # given iterable of pairs return key corresponding greatest value def argmax(pairs): return max(pairs, key=lambda x: x[1])[0] # given iterable of values return index of greatest value def argmax_index(values): return argmax(enumerate(values)) # given iterable of keys , function f, return key largest f(key) def argmax_f(keys, f): return max(keys, key=f)

i have logic print out dates def get_y_axis dates = "" ed = date.today sd = date.today - 30 sd.upto(ed) |date| dates << date.strftime("%b %d") dates << "|" end return dates end it prints this => "jan 24|jan 25|jan 26|jan 27|jan 28|jan 29|jan 30|jan 31|feb 01|feb 02|feb 03|feb 04|feb 05|feb 06|feb 07|feb 08|feb 09|feb 10|feb 11|feb 12|feb 13|feb 14|feb 15|feb 16|feb 17|feb 18|feb 19|feb 20|feb 21|feb 22|feb 23|" the problem need every other day...not every day ideas mark's solution fine, wanted show each_with_index method def get_y_axis dates = [] ed = date.today sd = date.today - 30 (sd..ed).each_with_index |date, i| dates << date.strftime("%b %d") if % 2 == 0 end dates.join("|") end also, in solution, "|" appended after last date. guess dont want that.

finally after trial , errors have managed make work wanted. but advice make code more readable , simple seems made lot of unnecessary code archive wanted. what basicly is, if turn on server app @ time schedule task should running, start task , let run time left when should have started otherwise schedule run @ hour supposed run. so if schedule time 13:00:00 , should run 120 minutes , start app @ 13:30 run 90 minutes. if start after time, schedule next day 13:00:00. calendar calendar = calendar.getinstance(); calendar.set(calendar.hour_of_day, hour); calendar.set(calendar.minute, 0); calendar.set(calendar.second, 0); long start_time = calendar.gettimeinmillis() - system.currenttimemillis(); if (start_time < 0) { long minutes = (start_time*-1) / (60 * 1000); if (minutes > 0 && minutes < 120) { runtimeleft = 120 - minutes; threadpoolman

i have following code: msavedtime = new time();//????always returns america/new york double latitude = 40.09596; double longitude = -74.22213; double elevation = 0; timezone timezone = timezone.gettimezone(msavedtime.timezone); my first question is: how elevation information lat\lon combination? second question is: how timezone string lon\lan combination? above code provide timezone string clock on cell phone set (returns america/new york). want string according lat\lon setup me. try code use google time zone api: private string get_utc_datetime_from_timestamp(long timestamp){ try{ calendar cal = calendar.getinstance(); timezone tz = cal.gettimezone(); int tzt = tz.getoffset(system.currenttimemillis()); timestamp -= tzt; // dateformat sdf = new simpledateformat("yyyy-mm-dd hh:mm:ss",locale.getdefault()); dateformat sdf = new simpledateformat(); date

i have multiple activity. of activity have same buttons such "continue" or "cancel" etc. each of have different actions. question is, can use same id button's in different activity? is, can use "android:id="@+id="continue_button" continue button's in different activity. or should use "continue_button_1" "continue_button_2" ...........

if "id" set value in servlet class how can access value on jsp page. know there several methods helps fetch value using session management tired of it. please me out. thanks in advance. from servlet, set file name in request context: request.setattribute("filename", filenamestr ); in jsp write: <%=request.getattribute("filename")%>
