Non working negated boolean in knockout.js -


The markup below fails, but I can not understand that as a positive version (without an exclamation point) Works. Very silly but I had to ask.): 

  & lt; Div data-bind = "visible:! $ Root.showMe" & gt; Where (see in modal): self. ShowMe = Ko.Osabel (wrong);

Ah, classic! $ Root.showMe is a function that refuses to deny a function, thus it does not work. However, de-referencing the work with its value functions.

Valid markup is: 

  & lt; Div data-bind = "visible:! $ Root.showMe ()" & gt;

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control.
