IPython Permission Denied -


i'm encountering problem starting ipython notebook or ipython console in spyder results in error message "assertion failed: permission denied (......\src\err.cpp:247) , (in ipython notebook) kernel endlessly restarts.

i'm using anaconda installation of python on windows 7, , have same problems both ipython 1.1 , ipython 1.0. did not have problem when ran ipython versions before 1.0, before switched anaconda.

a google search finds instance of problem, suggests due interactions pyzmq , firewall. i've tried adding specific exceptions python , ipython firewall, , turning firewall off completely, no change. can run ipython in command line, neither notebook or console in spyder work (giving error above.)

any information helpful. couldn't find file err.cpp in folder \src\ in python installation, can't confirm triggers error has relation pyzmq or firewalls. no change made when turning off firewall or elevating command prompt. else can try?

i realise 2 years old, i've been able sort out similar problem, have been see more answers this.

in case wasn't windows firewall or virus scanner, employer's services group runs vnc on same port hardcoded 0mq, used ipython in anaconda.

enough people complained provided script move vnc port affected people, while logging change in own records, happy.

try doing "netstat -ab" command line, , check if listening on port 5905, ipython needs (at least in 2016, anaconda). you'll need use "run administrator" cmd. if can't use "netstat -a". difference b option list process has taken port, , in our case see vncserve.exe there. -a enough see listening ports.

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...
