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;     } }

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
