i need add dvd writing functionality application i'm working on. needs able write out files being grabbed "live" camera, on long period of time. can't wait until files captured before start writing them dvd, need write them out in chunks go along. i've looked @ imapi v2 , main problems seems need point files plan write out disk before start burning process. know has concept of "sessions", means can write dvd in several parts, before "close" it. but wondering if there other dvd writing sdk's allow writing files dvd , in particular files in memory. more efficient if didn't have write captured images out hard before burned dvd. the solution needs work under .net on windows xp , vista the primo burning engine .net works nicely.

"build page" 1 of items can add toolbar compile aspx page or ascx control working on. there keyboard shortcut it? i use ctrl + shift + b , rebuilds entire solution. you configure own keyboard shortcut clicking tools / options / keyboard , scrolling down build options. (there's ones build.buildpage or build.buildselection...)

i have site, contains several ashx handlers, on couple of handlers want reject non-ssl requests. there way can in code? if must programmatically, way i've done in past inspect url , "https" in it. redirect if don't see that. request.issecureconnection should preferred method, however. may have add additional logic handle loopback address.

which standalone windows gui application recommend use accessing subversion repository? edit: lot of people mentioning tortoise, looking application not shell extension. people questioning reasoning behind not wanting use shell extension. in our environment rather interact repository (when not using ide plugin) through management application , not navigate files through windows explorer. standalone clients for total stand alone synchro svn powerful , cross platform solution. looks native application on each of platforms. the subversion website includes listing of other standalone svn clients (most cross platform). [copied list below http://subversion.tigris.org/links.html#clients] esvn - cross-platform qt-based gui frontend subversion http://sourceforge.net/projects/esvn fsvs - fast subversion command-line client centered around software deployment http://fsvs.tigris.org/ kdesvn - subversion client kde http://www.alwins-world.de/wiki/programs/kdesvn ...

i profiling code measuring wall clock time. in order minimize error need run code long period of time. however, flash seems protect unresponsive scripts throwing exception after period of unresponsiveness, namely: error #1502: script has executed longer default timeout period of 15 seconds. is there way disable protection, or @ least extend timeout period? if publishing adobe flash cs/4/5 etc. goto publish settings. select "flash" @ bottom of screen there textbox says "script timeout" know can increase this, think limit 90seconds though can enter value here.

i'm trying use locationmatch match url in website's second-level subdomain not in it's third-level subdomain. because want password protect urls @ level. eg. level2.domain.com/some/url should match not level3.level2.domain.com/some/url than apply necessary directives password protect urls. does locationmatch match part or url ? don't think so, , if that's case, use achieve desired effect ? i think have break locations separate virtualhost blocks , use servername / serveralias appropriately specify domains want cover...

we implementing following log on mechanism our 3-tier application: user launches client application , - authenticates using windows session credentials (active directory) or enters ad credentials if user logged on windows session or enters user name , password if computer not on ad domain. i.e. sql server management studio log on box (+point 2. above). the solution came having 2 endpoints, 2 system bindings (one windows, other username client credential type). i wondering if there's way of having 1 endpoint custom binding magically allow mixed authentication (either windows or username)? also, why bad idea? thanks!

i trying make disorganized text file list suitable use python program. text file list of data seperated few spaces not in standard columns or organized. goal of program read through file using python , after each piece of data want there space, want make new line. output should list of data each term on 1 line. in addition there terms not want. terms want start "jj". here have far. note not run yet. looking finishing program select terms starting jj , make new line @ space after jj term. robert datafile = open ('c:\\textfile.txt', 'r') line_list = line.split(" ") x in line_list: if x.startswith("jj") : print line_list edit: want open file called textfile , have python keep lines of data start "jj". additionaly want each data on it's own line, why want seperate them using space after each ilne of data? clearer? lines = [item item in open('c:\textfile.txt', 'r').read().split(' ') i...

when doing integration tests either data access layer or majority of application stack. best way prevent multiple tests clashing each other if run on same database? transactions. what ruby on rails unit test framework this: load fixture data. each test: begin transaction # yield control user code rollback transaction end each this means that any changes test makes database won't affect other threads while it's in-progress the next test's data isn't polluted prior tests this zillion times faster manually reloading data each test. i 1 think pretty cool

i have nsimage different images inside it. positions of images inside of stay same time, need specify rectangle subimage @ position of rectangle inside of image. how done? why there multiple images inside of 1 image? premature optimization? in case, when draw image , 1 of parameters pass section of image want. normally, pass either bounds of image or 0 rect (which both mean same thing), can pass subrectangle if want. if destination rectangle larger source rectangle, scale (non-proportionally); if it's smaller, scale down (non-proportionally). adjust size of destination rectangle match of source rectangle if don't want scaling. if want leave drawing nsimageview, create empty nsimage of desired size , draw it, pass image image view. destroys whatever performance advantage you'd hoped gain mashing these 1 image. you create custom subclass of nsview, nsimageview, or calayer has property nsimage , property source rectangle, , draws section.

i'm trying implement data compression idea i've had, , since i'm imagining running against large corpus of test data, had thought code in c (i have experience in scripting languages ruby , tcl.) looking through o'reilly 'cow' books on c, realize can't index bits of simple 'char' or 'int' type variable i'd to bitwise comparisons , operators. am correct in perception? reasonable me use enumerated type representing bit (and make array of these, , writing functions convert , char)? if so, such type , functions defined in standard library somewhere? there other (better?) approaches? there example code somewhere point me to? thanks - following on kyle has said, can use macro hard work you. it possible. to set nth bit, use or: x |= (1 << 5); // sets 6th-from right to clear bit, use and: x &= ~(1 << 5); // clears 6th-from-right to flip bit, use xor: x ^= (1 ...

say creating facebook style app app engine. how handle user profile pics? as far know, have either store images in datastore or blobstore. means every fetch picture require going through dynamic handler , using @ least 20ms cputime. is there efficient way this? or app engine can't handle? you don't have issue anymore, since get_serving_url() doesn't use of cpu quota (only outgoing bandwidth , storage). plus gives scaling , cropping free.

i have set hibernate give me set<integer> convert internally , set<myobjecttype> ( myobjecttype can represented single integer). say, when hibernate calls void setmyobjecttypecollection(set<integer> theset) method iterate through elements in theset , convert them myobjecttype . when hibernate calls set<myobjecttype> getmyobjecttypecollection() allocate new hashset , convert myobjecttype s integer s. the problem every time call commit , hibernate deletes in collection , re-inserts regardless of whether element of collection has changed or collection has changed. while don't technically consider bug, afraid deleting , inserting many rows cause database perform unnecessarily slowly. is there way hibernate recognize though have allocated , returned different instance of collection, collection contains items used , there no need delete , reinsert them all? i think best way achieve goal use usertype . lets handle conversion sql own objec...

any time need write code put in code behind file. reason has seemed "right" way write code. based on of examples see online, lot of other people choose write code way too, seems putting code in aspx file allows same stuff offering few advantages. top of list being: easier make changes since no recompile. you have access code if can't find project in source control (this happened me). is there benefit having code in code behind file? there disadvantage putting code in aspx file? separating code markup results in cleaner structure, non-trivial pages. 1 of major benefits asp.net on asp classic.

in c , c++ variable can marked volatile , means compiler not optimize because may modified external declaring object. there equivalent in delphi programming? if not keyword, maybe work around? my thought use absolute , wasn't sure, , may introduce other side effects. short answer: no. however, not aware of situation in conservative approach of compiler change number of reads or writes if follow approach: when reading cross-thread visible location, save value local before doing further manipulation; similarly, restrict writes single assignment. the delphi compiler not perform common subexpression elimination (cse) on non-local location expressions when there calls non-inlined methods between expressions, compiler doesn't interprocedural optimization , not correct single-threaded code. so, may want use interlockedexchange() reads , writes force this; additionally, cause full memory barrier, processor won't reorder reads , writes either.

i have 4 side convex polygon defined 4 points in 2d, , want able generate random points inside it. if simplifies problem, can limit polygon parallelogram, more general answer preferred. generating random points until 1 inside polygon wouldn't work because it's unpredictable time takes. a. if can restrict input parallelogram, simple: take 2 random numbers between 0 , 1. we'll call u , v . if parallelogram defined points abcd such ab, bc, cd , da sides, take point being: p = + (u * ab) + (v * ad) where ab vector b , ad vector d. b. now, if cannot, can still use barycentric coordinates. barycentric coordinates correspond, quad, 4 coordinates (a,b,c,d) such a+b+c+d=1 . then, point p within quad can described 4-uple such that: p = a + b b + c c + d d in case, can draw 4 random numbers , normalize them add 1. give point. note distribution of points not uniform in case. c. can also, proposed elsewhere, decompose quad 2 triangles , use half-p...

good day! i'm trying determine how of video loaded (in seconds). when try (stream.bytesloaded / stream.bytestotal) * video.duration result not accurate because distribution of video stream size not uniform inside file. for example if video starts static part video title or blank screen, size of part less (in other words compressed better) other video fast movements. far understand mp4 adaptive , more movement in video more space take. i tried use seek points (time + offset) defined in mp4 , works , accurate, don't want depend on them. thanks advices! you correct video loaded may vary according compression. a better way handle might instead display buffer , show user how of buffer has been loaded. otherwise, might need fix videos constant bit rate can estimate how of video has loaded.
