c# - How to pass parameter to javascript dynamically -


I have a repeater control on the aspx page and in that page I have kept the checkbox when a user checks this box , Then I want to redirect to a page. To do this, I have also written a java script:

JS: 

  function update (eid) {window.location ( "Events.aspx Id =" + Id); }   
  The method has the following code:   
  Secure void rptEventReminder_ItemDataBound (Object Sender, RepeaterItemEventArgs e) {checkbox cbx = checkbox As e ITEM FontControl ("chkComplete"); Label labeled lbl = e.Item.FindControl ("lblEid"); If (CBX! = Null & LBL! = Null) {Int64 eid = Convert. ToInt64 (lbl.Text); Cbx.Attributes.Add ("onclick", "update (eid);"); }}   
 The ID that is passing as a parameter is unique in the database.  
  I get a JavaScript error:   
 
 JavaScript runtime error: 'EID' is undefined    
 
 , Which is considered as a JavaScript variable, therefore you get an error  
 
 JavaScript runtime error: 'EID' is undefined   < P> Now, in the C # code,  eid  is a variable You must have it  
  cbx.Attributes.Add ( "onclick", "Update (" + eid + ");");

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.

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...
