my team working on crappy old website , of pages still asp classic. however, we've migrated forms authentication using asp.net , wildcard mapping. works surprisingly except 1 thing: logged in users timing out quickly. after looking in logs appears people timing out after 20 minutes (which specified timeout due inactivity). so, our hypothesis asp classic pages not tripping whatever mechanism in forms authentication framework resets inactivity timer. i've googled around , read wildcard mapping post great gu still can't find else having problem. so, 1) have ever seen problem? , 2) what's best workaround? (other manually placing hidden frame in every janky asp page loads dumb .net page in background) update : slidingexpiration set true also : can't use perpetual sessions because need application time out after 20 minutes of inactivity. also, terrible site written interface stored in page. there's no simple piece of interface code slip javascript ...

i have written code in vb.net application send html e-mail (in case, lost password reminder). when test e-mail, gets eaten spam filter. 1 of things it's scoring badly on because of following problem: mime_qp_long_line raw: quoted-printable line longer 76 chars i've been through source of e-mail, , i've broken each line longer 76 characters 2 lines cr+lf in between, hasn't fixed problem. can point me in right direction? thanks! quoted printable expands 8 bit characters "={hex-code}", making messages longer. maybe hitting limit? have tried break message at, say, 70 characters? should provide space couple of characters per line. or encode email base64 - mail client can handle that. or set content-transfer-encoding 8bit , send data unencoded. know of no mail server unable handle 8bit bytes these days.

i'm curious if project exists attempts group (or most) of php's built-in functions more object-oriented class hierarchy. example, grouping string functions single string class, etc. i realize won't solve problems (unless modifications took place @ php source code level), since built-in functions still accessible in global namespace, make usability easier. to answer question, yes there exists several of libraries talking about. far 1 want use entirely different question. phpclasses , pear.org places start looking such libraries. update: others have suggested spl library , wraps many of built in php functions. there still lots of php functions not wrap. leaving still without silver bullet. in using frameworks such cakephp , zend (others too), have noticed attempt solve of these problems including own libraries , building basics such db connectivity frame work. frameworks may solution

just starting out in asp.net. have created login.aspx page in site , stuck on asp login control - that's did. welcome.aspx page won't show start page of site when debug - though set this. plus have edited web.config - (see below) - , still same thing. how make work have welcome.aspx page start default? <authentication mode="forms"> <forms defaulturl="~/welcome.aspx" loginurl="~/login.aspx" timeout="1440" ></forms> </authentication> if want users access welcome.aspx without being authenticated, put welcome.aspx in separate folder, , set new web.config in sub folder. fill out authorization section in web.config files in folder , subfolders accessible anonymous users, this: <authorization><allow users="?" /></authorization>

i thought simple it's presenting difficulties. if have std::string name = "john"; int age = 21; how combine them single string "john21" ? in alphabetical order: std::string name = "john"; int age = 21; std::string result; // 1. boost result = name + boost::lexical_cast<std::string>(age); // 2. c++11 result = name + std::to_string(age); // 3. fastformat.format fastformat::fmt(result, "{0}{1}", name, age); // 4. fastformat.write fastformat::write(result, name, age); // 5. iostreams std::stringstream sstm; sstm << name << age; result = sstm.str(); // 6. itoa char numstr[21]; // enough hold numbers 64-bits result = name + itoa(age, numstr, 10); // 7. sprintf char numstr[21]; // enough hold numbers 64-bits sprintf(numstr, "%d", age); result = name + numstr; // 8. stlsoft's integer_to_string char numstr[21]; // enough hold numbers 64-bits result = name + stlsoft::integer_to_string(numstr, 2...

i try learn scheme , test project wanted create simple website 1-2 database queries (mysql preferred, postgresql ok, too). i know it's not schemes domain still want see how far can come. sadly, seems i'm stuck @ using database , googling "scheme database" or other combination including words (as expected considering double meaning of scheme in case) not helpful. can give me hints on how access database scheme program? i read scheme code interfacing mysql client program i'd prefer more direct. thanks. gnu guile has database interface supports postgres, mysql , sqlite. called guile dbi . other scheme implementations may try are: sisc (can connect jdbc compliant database, including mysql) , spark-scheme (can connect odbc compliant database, including mysql , comes bundled sqlite). note scheme implementations has form of foreign function interface write own mysql->scheme connector.

a found article ( extend visual studio build process ) explained how override build targets in c# project file. tested this, , seems work well. however, want override build target in c++ project (with visual studio 2005). problem c++ projects use different xml. instead of having <project> root, c++ projects have <visualstudioproject> root. when add <target> tag c++ project file , try open project in visual studio, error: the following error has occurred during xml parsing: file: [ path project file ].vcproj line: 304 column: 30 error message: element 'target' unexpected according content model of parent element 'visualstudioproject'. the file '[ path project file ].vcproj' has failed load. how can override visual studio build target c++ project? or there better way customize happens during c++ build? in visual studio 2005 there no build "targets" c++ builds c++ build system not u...

i won't able explain enough, here goes... i have table similar this: id | foreign_key_id | a_number | some_other_info 1 1 100 red 2 1 200 blue 3 1 300 orange 4 2 100 green 5 2 200 yellow 6 3 100 brown i want max "a_number" particular "foreign_key_id" in table, return rest of record have info "some_other_info" column. i've found can accomplish via query this: from x in this_table group x x.foreign_key_id g orderby g.max(x => x.a_number) descending select g.where (x => x.foreign_key_id == g.key).orderbydescending (x => x.a_number).first() edit: or possibly more concise query: from x in this_table group x x.foreign_key_id g let maxanumber = g.max(x => x.a_number) orderby maxanumber descending select g.where(x => x.a_number == maxanumber).first() ...

how change overview rule background color in eclipse 3.4.0.i20080617-2000 (vertical bar on right of editing window annotations) ? general > editors > text editors > annotations allows change colors of marks not background of whole bar. it looks web searching skills getting weaker since cannot find anywhere ... i have same problem michal - seems non-customisable. i have trouble seeing of annotation marks in overview ruler due vista's lighter colouring. can change colour of marks, bar doesn't change colour. it looks way change change system colours windows.

suppose, objects of type a stored in db. here's way load specific 1 db using hibernate: org.hibernate.session session = ...; long id = 1; obj = session.load(a.class, id); if object id=1 doesn't exist objectnotfoundexception . there way check if such object exists without having catch exception? have smth like: org.hibernate.session session = ...; long id = 1; boolean exists = session.exists(a.class, id); if(exists){ // smth..... } couldn't find hibernate docs... you can use session.get : public object get(class clazz, serializable id) throws hibernateexception it return null if object not exist in database. can find more information in hibernate api documentation .

i using php / mysql login system. add remember-me it. basic mechanics of remember-me? involve adding new column table in mysql of user information stored, etc. ? thanks in advance, john there few different methods this. secure method add field mysql user table , have "remember_me" hash random hash generated. the hash should stored in cookie on users computer userid validation purposes long remembering period lasts (you should set remember me period in db timestamp security). when pull site, see if cookie isset, if authenticate hash userid. if validates considered logged in. if not validate, send them sign in page / not considered logged in. this how setup of sites. pain if login computer, no longer validated on computer using , have re-authenticate. security, me, more important them having login again due situation. edit: see comments below information regarding sessions / security.

i need use many many relationship in project , since dynamic data doesn't support natively, ask sample of implementation of it. i'm looking way both create new instances of target entity , add new m2m relationship record using existing instances create relationship. i'm on tight schedule, appreciated. david ebbo (the architect dynamic data) posted many-to-many field template on blog. note solution entity framework.

is there fixed point in md5 transformation, i.e. there exist x such md5(x) == x ? since md5 sum 128 bits long, fixed point have 128 bits long. assuming md5 sum of string uniformly distributed on possible sums, probability given 128-bit string fixed point 1 / 2 128 . thus, probability no 128-bit string fixed point (1 − 1 / 2 128 ) 2 128 , probability there fixed point 1 − (1 − 1 / 2 128 ) 2 128 . since limit n goes infinity of (1 − 1 / n ) n 1 / e , , 2 128 large number, probability 1 − 1 / e ≈ 63.21%. of course, there no randomness involved – either there fixed point or there isn't. but, can 63.21% confident there fixed point. (also, notice number not depend on size of keyspace – if md5 sums 32 bits or 1024 bits, answer same, long it's larger 4 or 5 bits).

how can check version of script against online file see if it's latest version? for clarification, i'm talking script wrote, not version of php. i'd incorporate way end user tell when i've updated script. to specify second (more simple) solution phjr proposed: have file version.txt on own public server , include following function deployed project/script: define('remote_version', 'http://your.public.server/version.txt'); // version of deployed script define('version', '1.0.1'); function isuptodate() { $remoteversion=trim(file_get_contents(remote_version)); return version_compare(version, $remoteversion, 'ge'); } version.txt should contain recent version number, e.g.: 1.0.2

what, if any, performance difference between following 2 loops? for (object o: objectarraylist) { o.dosomething(); } and for (int i=0; i<objectarraylist.size(); i++) { objectarraylist.get(i).dosomething(); } from item 46 in effective java joshua bloch : the for-each loop, introduced in release 1.5, gets rid of clutter , opportunity error hiding iterator or index variable completely. resulting idiom applies equally collections , arrays: // preferred idiom iterating on collections , arrays (element e : elements) { dosomething(e); } when see colon (:), read “in.” thus, loop above reads “for each element e in elements.” note there no performance penalty using for-each loop, arrays. in fact, may offer slight performance advantage on ordinary loop in circumstances, computes limit of array index once. while can hand (item 45), programmers don’t so.
