a quick update on how populating control

    private void refreshoptions()     {         list<string> objects = globals.thisaddin.utilities.listrobjectswithdetail();         stringbuilder name = new stringbuilder(100);         stringbuilder details = new stringbuilder(200);         node datarootnode = new node();         node dataparentnode = new node();         node datachildnode1 = new node();         node datachildnode2 = new node();         node datachildnode3 = new node();         node functionsrootnode = new node();         node functionsparentnode = new node();         int charlocation;         int indexchild;         int childlevel;         treemodel _model = new treemodel();         treeviewadv1.model = _model;         treeviewadv1.beginupdate();          datarootnode = new columnnode("data / values", "", "");         _model.nodes.add(datarootnode);          functionsrootnode = new columnnode("functions", "", "");         _model.nodes.add(functionsrootnode);          foreach (string obj in objects)         {             name.clear();             details.clear();             name.append(obj.trim());             charlocation = name.tostring().indexof(":");             details.append(name.tostring().substring(charlocation + 1).trim());             name.length = charlocation;              if (details.length >=10 && details.tostring(0, 10) == "function (")             {                 functionsparentnode = new columnnode(name.tostring(), "function", details.tostring());                 functionsrootnode.nodes.add(functionsparentnode);             }             else             {                 indexchild = name.tostring().indexof("$");                 if (indexchild > -1)                 {                     childlevel = name.tostring(0, indexchild).split('.').length - 1;                     name.remove(0, 1 + childlevel);                      switch (indexchild)                     {                         case 1:                             datachildnode1 = new columnnode(name.tostring(), "data / value", details.tostring());                             dataparentnode.nodes.add(datachildnode1);                             break;                         case 2:                             datachildnode2 = new columnnode(name.tostring(), "data / value", details.tostring());                             datachildnode1.nodes.add(datachildnode2);                             break;                         case 3:                             datachildnode3 = new columnnode(name.tostring(), "data / value", details.tostring());                             datachildnode2.nodes.add(datachildnode3);                             break;                     }                 }                 else                 {                     dataparentnode = new columnnode(name.tostring(), "data / value", details.tostring());                     datarootnode.nodes.add(dataparentnode);                 }              }         }         nodetextbox ntb = new nodetextbox();         ntb.datapropertyname = "text";         this.treeviewadv1.nodecontrols.add(ntb);         treeviewadv1.endupdate();     }

i spent time looking @ treeviewadv sample project. looked "folderbrowser.cs" winform did have below nodemousedoubleclick event. correctly wrote node tot console.

        private void _treeview_nodemousedoubleclick(object sender, treenodeadvmouseeventargs e)     {         console.writeline(e.node);     }

if use same event e.node = "" although node populated.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
