c++ - 'TraceEvents' undefined; assuming extern returning int -


i trying convert our existing driver code using makefile visual studio 2013 msbuild.

i have include header files , source code. project created askmdf driver.

i have enabledwpp tracing, , inserted 3 parameters use 

-km (in trace kernel-mode components --> yes (-km) )    -func (in functions generate trace messages --> traceevents(level,flags,msg,...))    -gen (in specify template file --> {km-wdfdefault.tpl}*.tmh)

when build project, error returns as: 

'traceevents' undefined; assuming extern returning int 'dbg_pnp' : undeclared identifier

i not sure why happening. think missing steps. please direct me might have missed.

try starting new project , selecting "visual c++" -> "windows driver" -> "usb" -> "kernel mode driver, usb (kmdf). driver has wpp tracing set , builds out of box.

you should particularly take @ the trace.h file included project , comment block @ bottom; know we've had problems when omitted.

the comment block looks this:

// comment block scanned trace preprocessor define our // trace function. // // begin_wpp config // func trace{flag=mydriver_all_info}(level, msg, ...); // func traceevents(level, flags, msg, ...); // end_wpp

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...
