c# - DataGridView listing selected item from ListBox -


There is a list list from the database on my form1 (bindsourceed).

On my form, I have kept a datagrid view and would like to show data from the list selected on the Form 1. 

  Binding source binding source 1 = new binding resource (); BindingSource1.DataSource = s to db.Filmek where s.Filmcim == (string) select f.lBfilmlista.SelectedValue s; DataGridView1.DataSource = Binding Source 1;   
 The problem above my code is that it lists my first movie for the first time, whether I select another film or not from the list box on my form 1. How should I always show selected items from the catalog?   
 
 
 index change event list of selected list list ......  < P> The reason for this data source will be called for only one time (in the beginning)  
 If you use the selected index change event list box every time the data source will bind and you will receive whatever you want ....  
 All the best

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.

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...
