c++ - How can I change the border? -

-

I create a simple window with wxwidgets How can I change the border? Also, how can I call deleted function (onclos) with the right arrow button press? 

  #include & lt; Wx / wx.h & gt; Square _frame: public wxframe {public: _Frame (wxFrame * frame, const wxString and title); Private: Zero onClose (wxCloseEvent and Event); DECLARE_EVENT_TABLE ()}; BEGIN_EVENT_TABLE (_Frame, wxFrame) END_EVENT_TABLE () _Frame :: _ frame (wxFrame * frame, constant wxString & title): wxFrame (frame, -1, title) {} zero _Frame :: OnClose (wxCloseEvent & Event) {Destroyed (); } Class _App: Public wxApp {Public: Virtual Bull OnInit (); }; IMPLEMENT_APP (_App); Bool _App :: OnInit () {_Frame * frame = new_frame (0L, _ ("wxWidgets app template")); Frame & gt; Show (); Back true; } Right after the window closes on the item "itemprop =" text "> 
 after the" div class = "

Then there is a need:

header file: 

  zero onChar (wxKeyEvent & incident);

Source file: 

  zero _Frame :: OnChar (wxKeyEvent & Incident) {if (event.GetKeyCode () == WXK_RIGHT) {wxCommandEvent Pass (wxEVT_CLOSE_WINDOW); AddPendingEvent (Nearby); } Event.Skip (); } BEGIN_EVENT_TABLE (_Frame, wxFrame) EVT_CHAR (_Frame :: OnChar) END_EVENT_TABLE ()

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
