c# - NHibernate JOIN to temp table -


i want work in sql, populating temp table, , join temp table using nhibernate createsqlquery final results. on version 1.2.0.4000 of nhibernate , seem having problems accessing temp table in later query, though i'm in same session (i believe means i'm in same sql session/connection well). below simplified version of code

public void work() {     sqlconnection connection = (sqlconnection)session.connection;      sqlcommand command = new sqlcommand                      {                          commandtype = commandtype.text,                          commandtext = "select id = 1 #temptable",                          connection = connection,                      };      if ( session.transaction != null && session.transaction.isactive )     {         session.transaction.enlist( command );     }      command.executenonquery();      // simplified example, should have temp table #temptable 1 row containing values id = 1      // trying fetch list of account objects id exists in #temptable.     // @ point, error "invalid object name '#temptable'."     ilist<account> accounts = session.createsqlquery(@"         select *           account           join #temptable tt             on a.id = tt.id")         .addentity("a", typeof(account))         .list<account>();      // work on accounts list }

sessions connections on demand, not guaranteed same connection back. there 2 possibilities same connection every time:

  • using sessionfactory.opensession(myconnection); ties session provided connection.
  • implement iconnectionprovider pooling of connections

option 1 definitly easier

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
