c# - DataBinding between multiple controls and a single object -


just getting started data binding in c# , looking help. below binding statements break (visible property stops toggling mybool & myboolinverse) when line binding selecteditem of combo box myenumvar of businessobject executes. binding directly object instead of bindingsource, or binding selectedvalue instead of selecteditem, has same effect. further, value of myenumvar doesn't change selections combo box. doing wrong?

public partial class form1 : form {     bindingsource bs = new bindingsource();     private businessobject bo = new businessobject();      public form1()     {         initializecomponent();         bs.datasource = bo;          // checkbox determines type of dialog display.         boolcheckbox.databindings.add("checked", bs, "mybool", true,             datasourceupdatemode.onpropertychanged);          truebox.databindings.add("visible", bs, "myboolinverse");         falsecombobox.databindings.add("visible", bs, "mybool");         falsebox.databindings.add("visible", bs, "mybool");         falsebutton.databindings.add("visible", bs, "mybool");          myenumcombobox.datasource = enum.getvalues(             typeof(businessobject.myenum));         // line below breaks above bindings, same selectedvalue.         myenumcombobox.databindings.add("selecteditem", bs, "myenumvar");     } } class businessobject : inotifypropertychanged {     public enum myenum { red, blu }     myenum _myenumvar;     public myenum myenumvar     {         { return _myenumvar; }         set         {             if (value != _myenumvar)             {                 _myenumvar = value;                 notifypropertychanged("myenumvar");             }         }     }      private bool _mybool;     public bool mybool     {         { return _mybool; }         set         {             if (value != _mybool)             {                 _mybool = value;                 myboolinverse = !value;                 notifypropertychanged("mybool");             }         }     }      private bool _myboolinverse;     public bool myboolinverse     {         { return _myboolinverse; }         private set         {             if (value != _myboolinverse)             {                 _myboolinverse = value;                 notifypropertychanged("myboolinverse");             }         }     }      public businessobject()     {         myboolinverse = !mybool;         myenumvar = myenum.blu;     }      // boilerplate inotifypropertychanged implementation & helper.     public event propertychangedeventhandler propertychanged;     private void notifypropertychanged(string propertyname = "")     {         propertychangedeventhandler handler = propertychanged;         if (handler != null)         {             handler(this, new propertychangedeventargs(propertyname));         }     } }

visible property has problems binding. try manual 'binding'. along lines of

truebox.visible = bo.myboolinverse; bo.propertychanged += (s, e) => {    if(e.propertyname == "myboolinverse")      truebox.visible = bo.myboolinverse;  };

edit: also, binding myenumvar not working beacause not declared public property.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

java - Are there any classes that implement javax.persistence.Parameter<T>? -

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
