hi i'm new eclipse ide c/c++ developer(i'm using eclipse helios c/c++) i've made small program #include<stdio.h> #include<conio.h> main() { printf("hello eclipse c c++"); } and when trying run it, getting error "launch failed. binary not found" though cdt c/c++ installed can body me out? what c compiler using under covers there? people include conio.h invariably using turbo c - don't know why, it's antiquated , can better free compiler (in terms of both cost and freedom) in gcc (should pretty-well standard on linux distro, or hands on mingw if you're running under windows). try following instead: #include <stdio.h> int main (void) { printf("hello eclipse c/c++\n"); return 0; }

i've been looking around see if there exists way prevent viewers using right click options download images upload website. know people can @ image url in page source, , wondering if suggest way prevent them being taken, disabling save image option. this unsolvable problem. as long want people see images, cannot prevent them saving them via number of methods (e.g. screenshots). measures might think of annoy users, without preventing them doing want anyway. consider people watching images have interest in them (otherwise not watch them in first place), there have motive them keep copy. the way reliably prevent people saving images never let them copy them onto computers in first place (and remember: showing on computer entails making copy). one solution invite people place can view image on screen control, , not let them take pictures. think of modern cinemas security people night sights watch spectators , pull out might have been handling camera device.

the android system has flag called "unknown sources" allows install applications non-market sources. if sign application described on android developer website (i.e. certificate created using private keys got google), , decide not publish application on android market, host on own site. will application considered non-market android system ? still install "unknown sources" option turned off ? "unknown sources" allows installation of applications via download links (.apk files browser) , has nothing code signing. applications need signed , should zipalign'd before posting them. unlike other platforms (like blackberry), requirement application signed using private key control or own. recommend against using keys not own. if use private key other people can obtain, other people can post updates application system trust. the short answer no, not install via own web site "unknown sources" disabled on device.

i have several custom objects in nsarray, need search through objects , fnd index of object has property matches string. should using each loop? need relatively fast search each time new character entered in textfield. nspredicate neat, overkill (and won't give index of found object; object itself). the paired array approach, work, feels odd me (probably because it's using paired array). i either use for() loop (and break; when found looking for), or use block enumerator: __block nsinteger indexofmatchingobject = nsnotfound; [myarray enumerateobjectsusingblock:^(id obj, nsuinteger idx, bool *stop) { if ([[obj property] doeswhatimlookingfor]) { indexofmatchingobject = idx; *stop = yes; } }]; or different variant: nsinteger indexofmatchingobject = [myarray indexofobjectpassingtest:^(id obj, nsuinteger idx, bool *stop) { return ([[obj property] doeswhatimlookingfor]); }];

i know can git branch --all , shows me both local , remote branches, it's not useful in showing me relationships between them. how list branches in way shows local branch tracking remote? very porcelain command, not if want scripting: git branch -vv # doubly verbose! note git 1.8.3, upstream branch displayed in blue (see " what branch tracking (if anything) in git? ") if want clean output, see arcresu's answer - uses porcelain command don't believe existed @ time wrote answer, it's bit more concise , works branches configured rebase, not merge.

my setup windows xampp server, curl enabled, , git , hudson installed. hudson polls git every minute changes, , if finds them, creates build. use build testing server. works fine. i set post-receive hook on central remote repository runs force build function of hudson. i've created post-receive file called "post-receive" in hooks directory in central git repository, 1 pushed developers' local branches. each push own branch on central repository. want run post-receive build after every push, instead of having hudson poll git every minute. when open shell remote server , run "post-receive" in hooks folder, runs. isn't being called when people push local repository copies central one. maybe i'm not explaining right, it's how understand git. the post-receive code 2 lines: #!/bin/sh curl http://myserver.com:8080/hudson/job/myjobname/build?token=mytoken again, when open shell , run this, works, when pushes it, nothing happens, until m...
