sas has 32 character limit table- , column-names. have scenario want select table , join table b (where table b has name above 32 characters). if try write in proc sql, error saying table b has name exceeding 32 characters. anyone know how can arround this? assuming working non-sas dbms, sql server, should use passthrough sql process select, works rdbms's syntax , doesn't have 32 character limitation. ie: proc sql; connect oledb (... init string ... ); create table work.mydata select * connection oledb ( ... sql server or whatever syntax ... ); quit; you ask dba construct view had < 32 character long name.

i want last 3 passwords used (set) user , don't want set them again when going set again same password. api should use password history. visit link https://developers.google.com/admin-sdk/directory/v1/guides/manage-users https://developers.google.com/admin-sdk/directory/v1/reference/users/update afaik, there no "previous password" in of apis. i use one-way hash function save last passwords inside datastore table, , compare these. i know of no google product offer that.

i working on countdown using moment.js. nice if have conditional formatting. here have var count_down = moment().hour(23).min(30); alert( count_down.format('h[h ]m[min ]s[s]') ); that displays: 0h 43min 20s i know if there format expression var format = 'h[h ]m[min ]s[s]'; if (count_down.hour() === 0) format = 'm[min ]s[s]'; alert( count_down.format(format) ); displaying: 43min 20s i have not seen in doc though. a moment object represents time-of-day, not make sense count-down. should use moment's duration object purpose instead. moment doesn't yet have direct support formatting durations, this: var d = moment.duration('23:30'); var s = (d.hours() > 0 ? d.hours() + 'h ' : '') + d.minutes() + 'min ' + d.seconds() + 's'; alternatively, can try moment-duration-format plugin, still have handle conditional evaluation yourself.

.formwrap input[type="text"] { font-size: 12px; } .bigger { font-size: 14px } <div class="formwrap"> <input type="text" class="bigger" /> </div> why above not make text of input field 14px? when using input[type="text"] selector how can target particular class child of formwrap ? is there better method give inputs particular style able make adjustments inputs (hopefully based on class)? the first selector has higher specificity .bigger class. to increase specificity of .bigger class, this: .formwrap input[type="text"]{ font-size: 12px; } .formwrap input[type="text"].bigger{ font-size: 14px } or (not recommended): .bigger{ font-size: 14px !important; }

situation : central widget of application have qmdiarea in tabbed mode (wrapped in custom class inherited qmdiarea ). when add first qmdisubwindow via addsubwindow() still fine, meaning window , contents maximized take space of qmdiarea . however, add second sub window, following problem arises: problem : content of second window not displayed, instead content first continues (despite fact second tab visually has focus), reduced in size. takes few pixels. if switch first sub window/tab (either clicking size-reduced widget automatically goes max size or selecting first tab header) , selecting 2nd again, fine = widget/editor of 2nd tab displayed , maximized. but until close second tab, in case content first displayed (as expected), again in small size! screenshot: another related test case: 1st tab created , displayed full size expected. if resize overall qmainwindow , faint border appears around widget in tab. appears in mixed state between maximized , normal mode border...

why 3d array print address after being dereferenced twice? please me understand code posted below, (assume array begins @ location 1002). int main() { int a[2][3][4]={ { 1,2,3,4, 4,5,6,7, 9,1,1,2 }, { 2,1,4,7, 6,7,8,9, 0,0,0,0 } }; printf("%u %u %u %u\n",a,*a,**a,***a); //a == *a == **a, print address 1002. why? } **a has type int * , points first int in 3d array *a has type int (*)[4] , points first row of 3d array a has type int (*)[3][4] , points first 2d array in 3d array &a has type int (*)[2][3][4] , points whole 3d array so pointers point same address. it's type of pointer different. following code may illustrate point. int main( void ) { int a[2][3][4]={ 1,2,3,4, 4,5,6,7, 9,1,1,2, 2,1,4,7, 6,7,8,9...

i using doxywizard. under expert tab, in input item-list, @ example_path, have included 2 paths, lead 1 .cpp file, each. however, in generated documentation, see one, regardless of order. in doxyfile, see this: example_path = ../../../inria/rkd/samaras/final/code/main_boost.cpp \ ../../../inria/rkd/samaras/final/code/main.cpp what missing? if there solution editing doxyfile directly, interested. example_path lists directories store example files. if want add example specific class, have reference in header file of class. example_path = ../../../inria/rkd/samaras/final/code /** \example main_boost.cpp * example of how use main_boost. */ /** \example main.cpp * example of how use main. */ see more info here: http://www.stack.nl/~dimitri/doxygen/manual/commands.html#cmdexample
