mongodb - Cannot serialize log message using NoSQLAppender in Log4j2 -


could guys demonstrate how use nosqlappender in log4j2 (2.0-beta8) mongodb ?

i'm using scala (although don't think it's relevant).

java mongo db driver have 2.11.2

appender throws following exception

2013-07-31 18:19:27,831 error exception occurred processing appender databaseappender java.lang.illegalargumentexception: can't serialize class org.apache.logging.log4j.level     @ org.bson.basicbsonencoder._putobjectfield(basicbsonencoder.java:270)     @ org.bson.basicbsonencoder.putobject(basicbsonencoder.java:174)     @ org.bson.basicbsonencoder.putobject(basicbsonencoder.java:120)     @ com.mongodb.defaultdbencoder.writeobject(defaultdbencoder.java:27)     @ com.mongodb.outmessage.putobject(outmessage.java:289)     @ com.mongodb.dbapilayer$mycollection.insert(dbapilayer.java:239)     @ com.mongodb.dbapilayer$mycollection.insert(dbapilayer.java:204)     @ com.mongodb.dbcollection.insert(dbcollection.java:148)     @ com.mongodb.dbcollection.insert(dbcollection.java:91)     @ org.apache.logging.log4j.core.appender.db.nosql.mongo.mongodbconnection.insertobject(mongodbconnection.java:61)

well, ended implementing transformer level enum this

class levelbsonencoder extends org.bson.transformer {   def transform(o: any): anyref =     o match {       case level: org.apache.logging.log4j.level => new java.lang.integer(level.intlevel())     } }  // used  org.bson.bson.addencodinghook(org.apache.logging.log4j.level.error.getclass, new levelbsonencoder())

if know more elegant solution let me know.

ps. well, quick. reported bug https://issues.apache.org/jira/browse/log4j2-330 , maintainers confirmed suggested fix incorporated repo.

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)...
