wpf - xamdatetimeeditor set default current time and date -


How to set default current time and date in xamdatetimeeditor instead of default spaces?

My code will not show the current date and time won down. This XML 

  & lt; In igEditors: XamDateTimeEditor Grid Roll = "12" grid. Column = "2" x: name = "date" visibility = "{budding datetimeVisible, converter = {static resource boolean switchability}}" height = "23" verification. Error = "validation_date" mask = "biting", "yyyy / mm / dd hh: mm: ss" dropdownbuttondisplaylame = "always" displaylame = "include" value = "{binding date, initial update, source trigger = property changes, validanddateter = True, notify validationErr = true} "text =" {binding date selected, update resource reset = asset changed, validanddateterter = true, notifyOnValidationError = true} "& gt; & Lt; igEditors: XamDateTimeEditor.ValueConstraint & gt; & Lt; IgEditors: Value Contrast Maximink = "{x: Static Siss: Datetime, Now}" Validate Type = "DateTime" /> & Lt; / igEditors: XamDateTimeEditor.ValueConstraint & gt; & Lt; / IgEditors: XamDateTimeEditor & gt;   
 In the rear code  
  public string error {get new notimplementedException (throw); }} Public string this [string columnName] {{string result = zero; If (column name == "date selected") {if (string.IsNullOrEmptE (date selected)) {result = "please select date"; }} Return result; }} Public Date Time Date Initial {Receive {this.dateInitial; } Set {this.dateInitial = value; This.NotifyPropertyChanged ("Date"); Trace.WriteLine ("dateInitial !!!!" + dateInitial); }}    
 
 
 I found out:  & lt; IgEditors: XamDateTimeEditor   
  NullText = "{binding source = {x: static system: datetime.Now}, string format = '{} {0: yyyy / MM / dd H: Mm: ss} '} "

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...
