java - The first sort property must be the same as the property to which the inequality filter is applied -


java.lang.illegalargumentexception: first sort property must same property inequality filter applied. in query first sort property vote inequality filter on createddate

i error when try run code below. there work around problem?

query query = new query("post");  long timeago = - timelimit; filter categoryfilter = new filterpredicate("postcategory", filteroperator.equal, category); filter createddatefilter = new filterpredicate("createddate", filteroperator.greater_than, timeago); filter compositefilter = compositefilteroperator.and(categoryfilter, createddatefilter); query.setfilter(compositefilter);  query.addsort("vote", sortdirection.descending);  list<entity> postsentitylist = datastore.prepare(query).aslist(fetchoptions.builder.withoffset(offset).limit(limit));

the code above trying reteive list of post entities based on category , created within last 24 hours. sort them how many votes have. has limit , offset pagination.

to avoid error, option add multiple sort orders below createddate first sort order:

.addsort("createddate", sortdirection.ascending)                 .addsort("vote", sortdirection.descending);

but have limitation results not sorted respect second property , have additional sorting @ client side. please read earlier post understand behaviour

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)...
