.net - Asp.net Label not updated after postbck. Need extra refresh -


On the page load I'm clicking on the button after entering the record in DB, I'm checking that the user was present or Not today and display the correct label The problem is that the post label is displayed incorrectly, but if I refresh, I see the correct label. 

  Protects the sub-handle Btn_Click (as object, ByVal and System.EventArgs as the sender) AttendBtn handles. ConnectionString con = New SqlConnection (conString) con.Open () Dim cmd New SqlCommand ("Login in presence (UserID, Date, Presence_click) as New Connection String (" Attconnection ") as string conString = New SqlConnection Dim conString , Comments) value (@ USIDID, @date, @entendens_callic, @ comments) CMD parameter.Advate value ("@date", datetime.more) CMD parameter.Advate value ("@entensensical" GlobalVarAndFunc.CurrentCycle (2) ) cmd.Parameters.AddWithValue ("@ Comments", "") cmd.Parameters.AddWithValue ("UserID", GlobalVa rAndFunc.UserID) cmd.ExecuteNonQuery () con.Close () end sub   
 and on page load  
  protected sub page_Load (Subject as sub -Visitors, as byval e.EventArgs) as the system handle S. Me.Load If GlobalVarAndFunc.Has Attended then present_LB.Text = "you already participate today" Other appearance LL.Lect = "now be present" end if Checks for the GlobalVarAndFunc.Has function if the users are currently pressed on the present button   
 
 
 Understand the flow of the ASP page. The system button will execute your page load before the click event. So in your case, page_load was called at that time, you will get the price at that time which is already in DB because the system has not yet executed the click event. When click event is executed, your value goes to DB (your DB was not updated before this incident). Then on the next refresh you get the right value.  
 Solution: Results page_load code to get results in BTN_click event at one time

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...
