i have object attribute called value of type big decimal. in class definition have validates_numericality_of. however if i: a.value = 'fire' 'fire' ends getting typecast correct type before validation fires so: a.valid? => true how validation fire before typecast? thanks dan from activerecord::base docs : sometimes want able read raw attribute data without having column-determined typecast run course first. can done using <attribute>_before_type_cast accessors attributes have. example, if account model has balance attribute, can call account.balance_before_type_cast or account.id_before_type_cast . this useful in validation situations user might supply string integer field , want display original string in error message. accessing attribute typecast string 0, isn’t want.

i have object say. classa *obj1 = new classa; classa *ptr1 = obj1; classa *ptr2 = obj1; when delete ptr1; , affect ptr2 ? if can correct solution this? (assuming obj2 supposed obj1 ) classa *x defines pointer can point objects of type classa . pointer isn't object itself. new classa allocates (and constructs) actual object of type classa . so line class *obj1 = new classa; defines pointer obj1 , sets point newly allocated object of type classa . the line class *ptr1 = obj1; defines pointer ptr1 , sets point same thing obj1 pointing to, is, classa object created. after line class *ptr2 = obj1; , have 3 pointers ( obj1 , ptr1 , ptr2 ) pointing same object. if delete ptr1; (or equivalently, delete obj1; or delete ptr2; ), destroy pointed object. after doing this, pointer pointing object made invalid (which answers first question: yes, affect ptr2 in sense ptr2 won't pointing valid object afterwards). the correct solution depends on you...

i have couple of classes wish tag particular attribute. have 2 approaches in mind. 1 involves using attribute-extending class. other uses empty interface: attributes public class foodattribute : attribute { } [food] public class pizza { /* ... */ } [food] public class pancake { /* ... */ } if (obj.isdefined(typeof(foodattribute), false)) { /* ... */ } interface public interface ifoodtag { } public class pizza : ifoodtag { /* ... */ } public class pancake : ifoodtag { /* ... */ } if (obj ifoodtag) { /* ... */ } i'm hesitant use attributes due usage of reflection. @ same time, however, i'm hesitant on creating empty interface serving tag. i've stress-tested both , time difference between 2 3 milliseconds, performance not @ stake here. well, attributes, can create attribute in such way function doesn't propagate descendant types automatically. with interfaces, that's not possible. i go attributes.

i'm building highly scalable app, , need know data type use small strings (50-1000 chars). heard varchar fixed sized , therefore might faster, text, chars might stored in seperate clob, , pointer in row data. smaller, have significant performance hit? values in varchar columns variable-length strings. length can specified value 0 255 before mysql 5.0.3, , 0 65,535 in 5.0.3 , later versions. if have mysql 5.0.3 or later, , don't need more 65k characters, doesn't matter 1 use, because both text , varchar have variable size in storage. if have many texts less 255 characters, can save 1 byte choosing varchar. but on different aspect, choose data type more appropriate it. if store text, semantically text can exceed "standard" sizes easily, should use text datatype.

i can have number row consists 2 10 numbers. , row, have geometrical progression. for example: given number row: 125 5 625 have answer 5 . row: 128 8 512 have answer 4 . can give me hand? don't ask program, hint, want understand myself , write code myself, damn, have been thinking whole day , couldn't figure out. thank you. don't write whole program! guys, don't it, can't simple make division. have geometrical progression + show numbers. in 128 8 512 row numbers be: 8 32 128 512 seth's answer right one. i'm leaving answer here elaborate on why answer 128 8 512 4 because people seem having trouble that. a geometric progression's elements can written in form c*b^n b number you're looking ( b greater 1), c constant , n arbritrary number. so best bet start smallest number, factorize , @ possible solutions writing in c*b^n form, using b on remaining numbers. return largest result works. so examples: 125 5 625 ...

what of practical differences between using collectionviewsource.view.filter property opposed collectionviewsource.filter event? there situations use 1 on other or matter of preference? cheers, berryl edit: see docs "if view object comes collectionviewsource object, apply filtering logic setting event handler filter event." although nothing stops setting property on view, , doesn't why so. the advantage have found far in setting event on collectionviewsource can implement of filtering logic in 1 event handler , use view.refresh (or view.deferrefresh) invoke user changes filtering criteria. setting filter event in collectionviewsource mean event called when there no filtering needed make process less efficient. the official way of using filter event adding on filtering , removing later when filter cleared. viewsource.filter += viewsource_filter; then: viewsource.filter -= viewsource_filter; //how know how many events there are!? if use eve...

in app have main form button. clicking button, form (not auto-created in dpr) created , displayed; on form, placed tapplicationevents component , defined onidle event handler. event handler doesn't called! may depend because derived second form not tform other class, tchartbasicform (by means of vfi)? thank replies. massimo. hooking application's idle event can lead lot of debugging woes , other maintenance headaches, on form other main form. realize may not answer specific question (which hard @ point given vagueness), sure can't accomplish you're trying ttimer or tthread instead?

i writing script in bash on linux , need go through subdirectory names in given directory. how can loop through these directories (and skip regular files)? for example: given directory /tmp/ has following subdirectories: /tmp/a, /tmp/b, /tmp/c i want retrieve a, b, c. cd /tmp find . -maxdepth 1 -mindepth 1 -type d -printf '%f\n' a short explanation: find finds files (quite obviously) . current directory, after cd it's /tmp (imho more flexible having /tmp directly in find command. have 1 place, cd , change, if want more actions take place in folder) -maxdepth 1 , -mindepth 1 make sure, find really, looks in current dir , doesn't include ' . ' in result -type d looks directories -printf '%f\n prints found folder's name (plus newline) each hit. e voila!

this c# winform question. have datagridview bounded datatable. construct datatable myself, several datacolumn instances. when datatable bound datagridview, default, every column sortable clicking headers of datagridview. but sorting behavior "by default". seems sorted string. true if put code: datacolumn dc = new datacolumn("myobjectcolumn", typeof(myobject)); and myobject has overriden tostring() , has implemented icomparable interface. means if have told datatable how sort special column implementation of icomparable interface, datagridview still doesn't way expect. so how can let datatable sort data in way want? thanks answers. i recommend using defaultview of datatable. has built in sorting features little more extendable. easiest rowfilter, i'm not sure if you're looking if data types overridden .tostring() @ table level. edit: added code snippet a custom method maybe overrides or called during sort event of datagridview m...

i'm trying import org.apache.commons.fileupload.* being told not exist. i downloading jar: http://commons.apache.org/fileupload/ and placing on classpath. doing wrong here? most you're thinking of %classpath% environment variable. shouldn't that. jar file has go in /web-inf/lib folder of dynamic web application project. folder default covered webapp's classpath. bit decent ide (eclipse, netbeans, etc) automagically add build path whenever drop jar file in folder. when you're compiling using plain vanilla javac.exe in command console, have specify in -cp argument. update : assuming you're using windows , sitting in source root folder, here's how javac.exe should like: javac -cp .;/path/to/tomcat/lib/*;/path/to/web-inf/lib/* com/example/servlet.java note: wildcard works on jdk 1.6 or newer. otherwise you've specify libraries separately.
