c# - Sorting a listbox when a button gets clicked using MVVM -


i've been looking solution problem since yesterday. im building problem mvvm pattern. got 2 usercontrol, both containing listbox.

the first usercontrol called searchview contains listbox of project names, user can select , save applications local db.

enter image description here

when selected projects added event fired notify 2nd usercontrol named "projectview". usercontrol shows projects saved locally. seen @ picture below.

enter image description here

the problem want able sort listbox ascending name in projectview. if user first add "test project 2" , afterwords add "test project 1" "test project 1" shown in top of listbox.

i have tried use icollectionview , listcollectionview im confused @ moment.

so code looks this, in projectviewmodel needs sort listbox:

 public projectviewmodel() {      this.collectionview = collectionviewsource.getdefaultview(this.projects);  }   private observablecollection<projectwrapper> _project = new observablecollection<projectwrapper>();  public observablecollection<projectwrapper> projects  {      { return _project; }      set      {          _project = value;          onpropertychanged("projects");      }  }

xaml code:

<usercontrol.resources>     <collectionviewsource x:key="cvs" source="{binding path=projects}">         <collectionviewsource.sortdescriptions>             <scm:sortdescription propertyname="projectwrapper.project.name" />         </collectionviewsource.sortdescriptions>     </collectionviewsource> </usercontrol.resources>  <listbox name="projectslist" itemssource="{binding source={staticresource cvs}}" selecteditem="{binding path=selectedproject}" horizontalcontentalignment="stretch" borderthickness="0" grid.row="1" grid.rowspan="3" margin="0,0.4,-0.2,27.8">         <listbox.itemtemplate>             <datatemplate>                 <dockpanel>                     <textblock text="{binding path=projectmodel.name}" horizontalalignment="left" verticalalignment="center" padding="3,2,0,0" />                     <checkbox  ischecked="{binding path=isselected, mode=twoway, updatesourcetrigger=propertychanged}" horizontalalignment="right" verticalalignment="center" padding="0,2,5,0" margin="0,2.5,0,0" />                 </dockpanel>             </datatemplate>         </listbox.itemtemplate>     </listbox>

thanks in advance

call when adding element projects list

projects = new observablecollection<projectwrapper>(projects.orderby(x => x.name));

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).
