i'm developing application in visual studio using mvvm light , ninject. unfortunately, when try debug application , there's problem in 1 of viewmodels, instead of debugging code, this: this rather useless , impossible debug. now, if know error or have idea, can insert breakpoints there in code , visual studio show correct info, don't know error is. can't breakpoint every line of code in application. there way force visual studio past ui , debug actual code? there no need set owner of application main window. the correct way set owner of window in xaml follows <object> <object.owner> <window .../> </object.owner> </object> alternatively can set code behind // create window , make window owner window ownedwindow = new window(); ownedwindow.owner = this; ownedwindow.show(); the way have done wpf tries convert string "auto_calibrator_v0._05.mainwindow" window object not possible unless have type conv

i know if possible transpose efficiently wide long using proc sql in sas. i'm aware proc transpose quicker method suggest below. 1 of objective avoid storing transposed table. let's example, have table1 id| a| b| c| d _____________________ 1| 100|3500|6900| 10300 2| 200| 250| 300| 350 3| 150| 32| 400| 204 4| 200| 800|1400| 2000 and want turn into id|col1| col2| ______________ 1| a| 100| 1| b| 3500| 1| c| 6900| 1| d| 10300| 2| a| 200| 2| b| 250| 2| c| 300| 2| d| 350| 3| a| 150| 3| b| 32| 3| c| 400| 3| d| 204| 4| a| 200| 4| b| 800| 4| c| 1400| 4| d| 2000| i this; select id, 'a' col1, col2 table1 ~="" union select id, 'b' col1, b col2 table1 b ~="" etc but highly inefficient. any idea? thanks. if you're in sas , use proc transpose option. there no particularly way in proc sql; while many sql variants

how can configure intellij ide point javafx sdk ? recommendation - use later java version (7u6+) , idea's native javafx support at minimum, use intellij idea version includes javafx support (e.g. intellij idea 12.1 +), javafx distribution intellij idea javafx plugin supports (i believe that's java 7u6+). using latest stable versions of both of these tools provide best results. setup , use documentation intellij idea javafx 2.x+ plugin provided jetbrains . as java7u6+ includes javafx, don't need install , use separate javafx sdk such java 1.6 javafx sdk linked in question. if must use java 6 this approach not recommended. install javafx sdk , use javafx ant tasks build , deploy application. search jfxrt.jar file in distribution , create library added idea module's compile classpath. makes idea aware of javafx classes. some things consider: unlike later javafx releases, javafx 2.x sdk java 6 works on windows. after february 2013,

i trying make multiple items draggable can dragged 1 droppable. if dropped outside of droppable revert. of code works except 1 bug: user drags item droppable. drags out (executes out function) fails drop in droppable (revert happens, drag goes previous droppable). has happened droppable can accept drag (since drag left, executing out) while drag never left due revert. i have been trying resolve several of hours , have gone through api. tried have callback function revert due confusion on how retrieve draggable's droppable, stuck. //revert if not dragged draggable. $( "[id|=drag]" ).draggable({ revert: 'invalid', revertduration: 350 }); $( ".dropzone" ).droppable({ drop: function(ev,ui) { $(this).droppable('option', 'accept', ui.draggable); //only accept current drag. }, out: function(ev, ui) { $(this).droppable('option', 'accept', '[id|=drag]');//now can accept drag. } })

i'd provide webhosting service on vps running glassfish v4. means many domains 1 shared ip address of vps. know there problems ssl certificates of many domains 1 ip , sni extension may solve problem (right?). question is, whether glassfish supports this. thanks according glassfish 4 security guide, https://glassfish.java.net/docs/4.0/security-guide.pdf , there not support sni. however, it's bad practice imo (though still debated many), expose glassfish directly internet. i solve problem running apache server mod_ajp_proxy , connected jk-listener on glassfish.

if have object, this var o = { test : 1 } and have second object, 1 of it's keys should value of o.test. this: var o2 = { o.test : "bla" } i know not possible, there better (cleaner) way do now? currently dow this: var o2 = {}; o2[o.test] = "bla" i guess there better way this? i guess there better way this? assuming i've understood question correctly no, not really. way you've shown way it. there no way use dynamic key inside literal itself, have declare first , assign property separately: var o2 = {}; o2[o.test] = "bla"; o2; // { 1: "bla" } update the full details given in spec . here's grammar object literal property identifiers: propertyname :      identifiername      stringliteral      numericliteral the stringliteral production self-explanatory. here's identifiername production does: the production propertyname : identifiername evaluated follows:
