c# - PropertyChanged events need to fire once per click -


I am sitting in a scenario where I believe my system is starting to start scaling issues and I believe that this is caused by not doing anything "right way"

Basically I have a silverlight project and in this particular domain there are many dependencies in my model < Pre> int_Wight; Public gut weight ({return _Wight;} set {if (value! = _Wight) {_Weight = value; RaisePropertyChanged ("weight"); then}

After that model, My app also pastes an additional event on the converted event in the property 

  myObject.PropertyChanged + = UpdateUI;   
 My update does a bunch of updated UI graphic content It produces images that bindings are used.  
 And it works well.  
 But now suppose that my weight Property also has an effect on other properties, they also close the changing events of their properties (as they should, so all UI areas to be bound to those qualities will be updated), but then update the Ui all the time It means that if a property also affects 3 other properties, then the updated III will be trapped 4 times when it only results after the final property.  
 Anything, just inefficient and architecture seems wrong.  
 So what is essentially what I am asking, how can I get it that my UpdateUI only   
 
 
 Your architecture is closed once a series of properties changes I have two ides to know.  
     
  1.  Here is what I will choose, but more effort is needed - DesignUse UpdateUI method so that it can update according to the changed property, complete one property of one of hundreds of visual modals changes Do not refresh the way. For example, if a person view model changes, only update it.  
  2.  Run a pending layout update once in a few seconds. For example, you can start some types of timers that will check whether vertical layouts are updated (you have to do the architecture yourself) and have to execute them, or the last of them depend on you. It can be efficient but should be carefully prepared.   
     I'm not familiar with Silverlight, only WPF, but I think the same principles apply.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
