i've been writing c / c++ code twenty years, , know perl, python, php, , java well, , i'm teaching myself javascript. i've never done .net, vb, or c# stuff. managed code mean? wikipedia describes it as code executes under management of virtual machine and says java (usually) managed code, so why term seem apply c# / .net? can compile c# .exe contains vm well, or have package , give .exe (a la java)? in similar vein, is .net language or framework , , "framework" mean here? ok, that's more 1 question, who's been in industry long have, i'm feeling rather n00b-ish right now... when compile c# code .exe, compiled common intermediate language(cil) bytecode. whenever run cil executable executed on microsofts common language runtime(clr) virtual machine. no, not possible include vm withing .net executable file. must have .net runtime installed on client machines program running. to answer second question, .net framework...

i've got many, many mp3 files merge single file. i've used command line method copy /b 1.mp3+2.mp3 3.mp3 but it's pain when there's lot of them , namings inconsistent. time never seems come out right either. as thomas owens pointed out, concatenating files leave multiple id3 headers scattered throughout resulting concatenated file - time/bitrate info wildly wrong. you're going need use tool can combine audio data you. mp3wrap ideal - it's designed join mp3 files, without needing decode + re-encode data (which result in loss of audio quality) , deal id3 tags intelligently. the resulting file can split component parts using mp3splt tool - mp3wrap adds information idv3 comment allow this.

how use separate stylesheet opera? like: <![if !ie 6]> <link rel=»stylesheet» type=»text/css» href=»ctyle.css» /> <![endif]> but opera? (for versions of opera) i don't think can without sniffing user agent server side code or javascript. besides usual caveats of user agent sniffing, server side code more reliable wouldn't require javascript enabled. there may possibly opera specific hacks, implementing these worse sniffing imo. if there layout problems, google bug , see solutions exist fix. may not need separate stylesheet.

why test program result in java.lang.illegalmonitorstateexception ? public class test { static integer foo = new integer(1); public static void main(string[] args) { synchronized(foo) { foo++; foo.notifyall(); } system.err.println("success"); } } result: exception in thread "main" java.lang.illegalmonitorstateexception @ java.lang.object.notifyall(native method) @ test.main(test.java:6) you have noted correctly notifyall must called synchronized block. however, in case, because of auto-boxing, object synchronized on not same instance invoked notifyall on. in fact, new, incremented foo instance still confined stack, , no other threads possibly blocked on wait call. you implement own, mutable counter on synchronization performed. depending on application, might find atomicinteger meets needs.

we have oracle db running on linux. when data ready report, value placed in table in db. presently app scheduled run every 10 seconds check value , if it's there prints out report. not prety. how can make pretty? i sort of envision oracle db somehow triggering windows server print (tcp/ip? small service listening on windows box) windows app fires when it's time work. how linux/oracle system "signal" windows box? actually, polling quite quick, cheap, resilient, , best of - implemented method of achieving goal. remote db-initiated triggers wonderfully sexy, , simple using cups samba , printing directly linux box. or complicated full two-way rpc error checking. either way, don't fix things aren't broken.

in .xsd file typed dataset in .net, there's <connections> section contains list of data connections i've used set datatables , tableadapters. there times when i'd prefer not have there. instance, prefer pass in connection string custom constructor , use rather 1 in settings, .config, etc. but seems if remove connection strings section (leaving empty), or remove section entirely, dataset code-generation tool freaks out. whereas if don't remove them, dataset gripes when put in different project because can't find settings connection strings. is there way can tell typed dataset not worry connections? (obviously i'll have give connection if change tableadapter sql or stored procs, should my problem.) this has bugged me long time , did testing recently. here came with. record, i'm using vs 2008 sp1. datasets will store connection string information whether want them or not. you can make sure datasets won't store password...

i'm writing basic sprite engine own amusement , better aquainted java's 2d api. making use of large numbers of separate .png files transparent backgrounds represent various sprites , different frames of animation need. 'real world' game development projects seem make use of 'sprite sheets' contain multiple sprites or frames of animation within single file. also, rather making use of native image transparency support, people nominate arbitrary colour not appear in sprite pallette transparent colour. how 1 manage file programatically? how know 1 sprite starts , next begins how deal transparency there may other factors i've not thought of here, may add list above think of things or people make suggestions (please in comments). i use xml files generated simple sprite editor store sprite collection of (optionally animated) poses, in turn collection of frames or cells. frames store per-frame information x , y offset of frame in sheet, cell widt...
