c# - Tri State Chech box for ToolStripDropDownButton -


i have statusbar strip toolstripmenuitems. need gruop toolstrip menu items , implement tristatecheckbox functionality,

  1. is possible create checkbox toolstripmenitems?
  2. if not possible point 1, how add treeview statusstrip. enter image description here

to have three-state menu item, can set checkstate of each toolstripmenuitem indeterminate, checked or unchecked.

enter image description here

also if want use tree-view control (which doesn't have builtin support three-state check boxes) or this control, should know, can host control in drop-down using toolstripcontrolhost. example, here toolstriptreeview control:

using system.componentmodel; using system.windows.forms; using system.windows.forms.design; [toolstripitemdesigneravailability(toolstripitemdesigneravailability.contextmenustrip)] public class toolstriptreeview : toolstripcontrolhost {     [designerserializationvisibility( designerserializationvisibility.content)]     public treeview treeviewcontrol { { return (treeview)control; } }     public toolstriptreeview() : base(createcontrol()) { }     private static treeview createcontrol()     {         var t = new treeview();         return t;     } }

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
