java - Access Struts2 locale in Spring AbstractRoutingDataSource -


our application uses struts2 internalization , spring abstractroutingdatasource dynamic database changes. changing language, corresponding language database should selected.

so below code makes dynamic database selection using spring routingdatasource. 

public class routingdatasource extends abstractroutingdatasource {     protected object determinecurrentlookupkey() {         return languagecontextholder.getlanguagetype();     } }

spring routingdatasource working fine.

my problem how set locale on change. since stored in struts2, not able access in spring.

i found spring mvc org.springframework.context.i18n.localecontextholder this, since using struts2, how can above?

struts2 stores current locale in session default key ww_trans_i18n_locale. access session inside routingdatasource use actioncontext.getcontext().getsession() method.

// ...  if (actioncontext.getcontext() != null) {   map<string, object> session = actioncontext.getcontext().getsession();    if (session != null && session.containskey(i18ninterceptor.default_session_attribute)) {     locale locale = (locale) session.get(i18ninterceptor.default_session_attribute);   } }  // ...

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
