i have straight forward ui displays 3 250 x 180 images in uiimageview's want able show them in more interesting way , when ipad rotated landscape mode images overlap text etc. looks bit cheap. what options displaying 3 images more creatively? determine best way display images both orientations are. depending on how different things need be, got 3 basic options: 1) difference small, need tweak positioning. can accomplished adjusting images struts , springers on layout tab of @ nib editor. 2) need rearrange things make more sense when rotated. in case, implement willrotatetointerfaceorientation , adjust position of images in method. changes animated automatically, looks simple adjustments. 3) want give user different experience in both orientations. in case might want make separate view controllers both orientations. there quite few tutorials found if need approach. if matter of placing images in way fit, option 2 suitable one.

can create xib (with view) programmatically ? if no, why & if yes, how ?? xibs files, too, there's no technical reason why wouldn't able create 1 programmatically. expect no convenience methods create xibs however, purpose circumvent need create , configure ui elements programmatically, opposite of people use xibs for. if must create xibs though, open 1 in texteditor - you'll see consists of readable xml code. may take time work through keys , possibilities, creating xibs programmatically can done. edit: it's gonna hard, though.

my silverlight + asp.net mvc application following: 1) silverlight client sends request via httpwebrequest. 2) asp.net mvc connects sql server database (stored procedure) , gets xml data sends raw xml client (no web services or wcf). 3) silverlight client receives xml , deserializes xmlserializer class. 4) deserialized object manipulated, serialized , sent server. 5) asp.net mvc receives xml , directly sends database (stored procedure) shreded , saved appropriate table(s). is acceptable architecture? problem approach be? also, sl 3 there seems option use binary xml, don't see information how use without wcf. found wcf quite heavy, deliberately avoid it. me, asp.net mvc based restful architecture seems more appealing. above description may not restful, think quite close. thoughts welcome. i think wcf simplify scenario , open many options maybe don't need right useful in future (for ex. if decide add kind of client, or decide implement security mechani...

iterator = myhashmap.keyset().iterator(); while (it.hasnext()) { int next = it.next(); } that doesn't work because it.next() returns object. hashmap uses ints keys. of methods accept ints access hashmap. how can int value when looping through keys can pass other methods? you should use generics. map<integer, object> myhashmap; this gives keys integer (not int, cannot helped). integer can automatically unboxed: for (int key : myhashmap.keyset()){ } if want keys in ascending order, consider using treemap instead of hashmap .

ieee vhdl language reference manual defined limited set of standard packages.and not defined functionalities on standard types,such std_logic.so there no standard and2, inv components/operator. it seems altera's max+plus ii not support and2, inv component(if there are,please feel free correct me),but xilinx foundation does. why ieee vhdl standard library not become stl in c++ world? thanks. invert, and, or,... std_logic types are supported ieee libraries: a <= b , c d <= not e f <= g or h your synthesis tool automatically translate these expressions best implementation target technology (xilinx fpga, altera fpga, asic, ...). there no need explicitly instantiate technology specific components. instantiating technology specific components might obstruct optimizations. you should try write vhdl code technology independent . allows reuse code.

i have air application loads external swf when prompted user. in external swf, have class loads necessary fonts particular swf. when air application attempts load swf argumenterror: error #1508: value specified argument font invalid. ideas? thanks. i decided not load font libraries external swf used , opted use fonts loaded @ runtime main application.

i writing c# .net 2.0 application wherein when message expected received via serialport . if frame not received (i.e. times out) or determined invalid, need set error code using setlasterror . windows has plethora of error codes. there simple tool or reference narrow down proper error code use? additional info while throwing exception , handling higher stack preference, not option in case because application updating not designed take advantage of such useful feature. in "good old days" (c , c++), list of possible windows errors defined in winerror.h update: link below dead. not sure if file still available download, windows system error code definitions can found @ link. this file can found on microsoft's site (although surprises me little dated far 2003 - might worth hunting more recent version). but if you're getting (or wanting set) win32 error codes, this'll definition found.

here's setup: mytextfield bound key in shared user defaults controller. user can enter numbers in text field. each time application loads, load default preferences (from app's resources folder) using [[nsuserdefaults standarduserdefaults] registerdefaults: ... ] . mymenuitem 's title bound same key in shared user defaults controller. the issue: when mytextfield empty, mymenuitem receives default value loaded using registerdefaults: instead of value represents empty field (i expect 0 or nil ). for example, when nstextfield empty menu item receives "2", value loaded using registerdefaults: , instead of value means field empty. if comment registerdefaults: code, binding returns nil expect when there nothing in nstextfield . i tried mess around many of bindings' settings experiment placeholder values , looked @ cocoa bindings , user defaults docs not find solution. expected behavior: when text field empty, want mymenuitem reflect i...

i changing datagridview cell values programmatically, values not pushed bound datasource. pushed cells belonging selected row. how can ask datagridview push rows values datasource? edit: this code seems trick, may better solution? grid.currentcell = cell; cell.value = "some value"; grid.endedit(0); you shouldn't update datagridview cells, instead should directly update data source. if implements inotifypropertychanged , datagridview reflect changes automatically

i have matlab code requires time series data uniformly distributed in time produce answer. driver matlab code reads data file runs interp1 ( x, y, xi, 'cubic') on data after reads file because data not uniformly distributed in time. now have port process java add production process. matlab version isn't anemiable large numbers of data files , can't used in production. my actual question can find java library implements interp1 'cubic' method use when data read process? according matlab docs, 'cubic' same piecewise cubic hermite interpolating polynomial (pchip) interpolation. 'spline' produces unacceptable results. have looked @ apache commons-math , jama . drej. http://www.gregdennis.com/drej/ nonlinear least squares via regression on data sets. can specify lamda value ( goodness of fit) , cheaper fit data. it interpolate , extrapolate, don't extrapolate far; if want specific extrapolated far-field behavior ad...

how can convert time 10:30 seconds? there sort of built in ruby function handle that? basically trying figure out number of seconds midnight (00:00) specific time in day (such 10:30, or 18:45). you can use datetime#parse turn string datetime object, , multiply hour 3600 , minute 60 number of seconds: require 'date' # datetime.parse throws argumenterror if can't parse string if dt = datetime.parse("10:30") rescue false seconds = dt.hour * 3600 + dt.min * 60 #=> 37800 end as jleedev pointed out in comments, use time#seconds_since_midnight if have activesupport: require 'active_support' time.parse("10:30").seconds_since_midnight #=> 37800.0

can please me in sorting persistent store records in blackberry application? want sort in ascending , descending order... for sorting in blackberry can use simplesortingvector bad news is, simplesortingvector not persistable. sorting in persistent store have write own sorting method. vector info = (vector) store.getcontents(); now sort contents of vectors sorting algo.

i trying create program process table. i have implement class pcb (process control block) several fields such as: process name (a string) process priority (an integer) register set values (an object of class register set containing following fields: xar, xdi, xdo, pc. then program needs create process table data structure either array (max size 100 elements) or arraylist of type pcb, , initialize array data file "processes1.txt" process table arrraylist has print out contents each process. so questions are: 1. how many programs/classes have write? 3. first program creates process table arraylist of pcb. 2nd class pcb class defines pcb fields. 2. how first program initialize arraylist data text file? 3. use arraylist of arraylist? , how that? thank in advance. processtable, processcontrolblock, registerset sound starts. i'd create method in processtable called load(file file) uses file, , perhaps textreader read configuration. there many ways re...

i know cost of physical win32 thread context switch estimated @ between 2-8k cycles. estimates on cost of process switch? instead of asking estimates, i'd test it. start program like: #include <windows.h> int main() { (int i=0; i<1000000; i++) sleep(0); return 0; } then create parent program spawns (say) 32 copies of this, , uses waitformultipleobjects wait them finish. measure (wall) time start finish, , divide total number of process switches. of course, want run on relatively quiescent system meaningful result.

i have django project have been logging file using standard library logging module. variety of reasons change writes apache log files. i've seen quite bit of discussion of how mod_python, not mod_wsgi. how do project running under mod_wsgi? mostly, use logging , write sys.stderr . seems write apache error_log.

i'm attempting write basic dna sequencer. in that, given 2 sequences of same length, output strings same, minimal length of 3. input of abcdef dfeabc will return 1 abc i not sure how go solving problem. can compare 2 strings, , see if equal. there, can compare length-1 string size, i.e. if dfeabc contains abcde . however, how can program possible strings, down minimal size of 3 characters? 1 issue above example of length-1, i'd have string bcdef , compare that. the naive way every single substring of string , see if it's in string b. here's naive way of doing that: for ( int = 0; < a.length; i++ ) { ( int j = i+1; j <= a.length; j++ ) { if (b.contains(a.substring(i, j))) { //if longer last found match, record match } } } the more optimal way @ longer substrings first, first substring matches longest. for ( int length = a.length; length > 0; length-- ) { ( int = 0; + length < a.length; i++ ) {...

i have simple assignment professor wants do. pull in numbers text file , load linked list. don't want details have basic question. he provided function so: intlist* init_intlist( int n ) { intlist *lst; lst = (intlist *)malloc(sizeof(intlist)); lst->datum = n; lst->next = null; return lst; } this function used initialize linked list first element. asked define function signature: int insert_intlist( intlist *lst, int n ) so assume wants add linked list tried this: int insert_intlist( intlist *lst, int n ) { intlist* lsttemp; lsttemp = (intlist *)malloc(sizeof(intlist)); lsttemp->datum = n; lsttemp->next = lst; lst = lsttemp; free(lsttemp); } so thought process creates temporary node, assigns data value (datum) , assigns next pointer point current pointer pointing at. reassign main pointer newly created temp node. that way have instance 2 nodes: [new temp node] -> [prev initialized node] when step through code looks ...
