c# - How to make NLog terminate application on fatal errors? -


can somehow set event handler fatal errors in code? terminate application if such error happens, i.e. this:

void fail(string format, params object[] args) {   logger.fatal(format, args);   environment.exit(-1); }

however happen automatically:

logger.fatal(...); // logs error , invokes environment.exit(-1);

is there way setup kind of callback fatal errors or configuration option this?

yes, can using methodcall target (see https://github.com/nlog/nlog/wiki/methodcall-target)

here example:

namespace somenamespace {     using system;      public class myclass     {         public static void handlefataleventlog(string level)         {             if(level.equal("fatal", stringcomparison.ordinalignorecase))              {                 environment.exit(-1);             }         }     } }

and nlog.config file:

<?xml version="1.0" ?> <nlog xmlns="http://www.nlog-project.org/schemas/nlog.xsd"       xmlns:xsi="http://www.w3.org/2001/xmlschema-instance">     <targets>         <target name="m" xsi:type="methodcall" classname="somenamespace.myclass, myassembly" methodname="handlefataleventlog">             <parameter layout="${level}" />         </target>     </targets>     <rules>         <logger name="*" minlevel="fatal" writeto="m" />     </rules> </nlog>

ps: but, not recommend approach, logger should not shutdown application

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...
