winapi - How can I know the type of dc (Windows device context) with Windows API -

i got handle of dc (of type hdc ) under windows. can type of cd(memory dc, window dc ,printer etc.) windows apis? this in general not possible, , not necessary either. device context meant abstract underlying implementation. occasionally, however, helpful know, contents of device context displayed, adjust rendering, example. calling getdevicecaps nindex set technology retrieves information. doesn't allow discern between 4 device context types plus subtypes, though.

scala - playframework fall back configuration? -

how let playframework's configuration falls other configuration files if default 1 not exist. for example, default play use application.conf, if not exist, use c1.conf. if c1.conf not exist, uses c2.conf. i use play framework 2.3 in scala thanks. such feature doesn't exist in play framework. can specify file should used configuration passing 1 of possible properties startup script. available parameters described in documentation under section called specifying alternative configuration file . -dconfig.resource - allows choice file within application -dconfig.file - sets file outside of application -dconfig.url - uses file loaded given url if none of properties passed application, it'll use application.conf default one. to complete task, can write bash script verify whether script want run exists. if so, pass using 1 of aforementioned parameters or use different 1 otherwise.

Kafka consumer - how to add a topic -

in scenario, have n consumers (all consumers have 1 stream/no partitioning), each subscribed separate set of topics, how process new topics, added producers? should create new consumer each added topic? or can add topic working consumer? (how that?) or better keep 1 consumer group n consumers , not divide topics between n consumers(streams)? the initial config, described, topics devided between consumers of same consumer group not goood @ all. consumer not able fail=over each other, because have different lists of topics. kafka issue unnecessary rebalance. you need not add consumer each added topic - better consume such topics beginning, adding them common path /mytopics/* you better divide topics partitions , add new partitions if need. transparent , without effort.

makefile - GNU make is adding white space after -I (shared directory) option -

i'm trying use armclang compiler through gnu makefile, there clash between both tools when using -i option. for armclang compiler, -i means "adds specified directory list of places searched find included files.syntax -idir" without space. for gnu makefile ‘-i dir’ has same meaning (but space). in makefile have following: $(aarch32_bootobj): %.o: %.s @echo " [asm ] $<" @armclang --target=armv8a-arm-none-eabi -icommon/shared -c $< -o $@ when running makefile, i'm getting following warning , error : armclang: warning: argument unused during compilation: '-i common/shared' aarch32/shared/bootcode.s:32:10: error: not find include file 'boot_defs.hs' where boot_defs.hs exists under common/shared when running same armclang command outside makefile, works. therefore i'm assuming makefile has formatted -icommon/share option , added automatic space after -i. is there way run armclang command correctly? ...
