c# - SQL error with update -


I have a problem updating what's wrong?

Compiles the code, but when I click the click button, line -> Cmd.ExecuteNonQuery (); Did not work.

Here the error

Additional information: query with parameter '(@nmo int, @ rezerwoâ ???? INA) updated SETTT.amiejska = @no mo' parameter ' @rezerwo ', which was not provided. Inactivity 1: System.Web.UI.Page SqlConnection cn = new SqlConnection (@ "Data Source = (LocalBible) \ v11.0; Attach debuff filename =

Toaster (NMO); Td.miejsca = snmo; Cmd.ExecuteNonQuery (); cn.Close (); } Db.rezerwacjes.InsertOnSubmit (TC); Db.SubmitChanges (); Constructor of SqlParamter may have interpreted another parameter incorrectly (SqlDbType instead of the actual value)    
 
 
  cmd.Parameters.Add (New SqlParameter ("@ nmo", nmo) instead of  
; Cmd.Parameters.Add (new SqlParameter ("@Rezerozo" ???, Richero));   
 Try  
  cmd.Parameters.AddWithValue ("@mo", nmo); Cmd.Parameters.AddWithValue ("@Reservavou" ???, Richero);   
 Another point. Functionality can be stored with the default command type, try adding it to your code:  
  cmd.CommandType = CommandType.Text;

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...
