• How to stop Visual Studio from returning duplicates answers?

  - by Franck Mesirard

  In my team, we put all our projects (only 7 large ones) in the same solution. And since some code is common between project we tend to have the same file included in each project. This is fine and compiles/runs well. But when I do a global search in my solution, VS does a "stupid" search and goes through all the files in each project, without checking if a file has already been searched. This leads to longer searches whose results have duplicates. Do anyone know a fix for this issue?

• How to remove proxy from WebRequest and leave DefaultWebProxy untouched

  - by Elephantik

  I use FtpWebRequest to do some FTP stuff and I need to connect directly (no proxy). However WebRequest.DefaultWebProxy contains IE proxy settings (I reckon). WebRequest request = WebRequest.Create("ftp://someftpserver/"); // request.Proxy is null here so setting it to null does not have any effect WebResponse response = request.GetResponse(); // connects using WebRequest.DefaultWebProxy My code is a piece in a huge application and I don't want to change WebRequest.DefaultWebProxy because it is global static property and it can have adverse impact on the other parts of the application. Any idea how to do it?

• Sort NSFetchedResultsController results by user location

  - by cgp

  I have an application that contains some Locations in Core Data, and I want to show them to the user in order of proximity to the user's location. I am using an NSFetchedResultsController to serve the locations to the Table View. I thought about creating a virtual accessor method that returns the location's distance from the user, that would be calculated using a "global" CoreLocationManager, but it crashes with reason: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath distanceFromCurrentLocation not found in entity < NSSQLEntity Location id=4' I also give the user the option to sort alphabetically, so I would prefer it if I kept the NSFetchedResultsController, if possible. How should I do it? Thanks!

• How do you move the pointer up or down multiple lines with Emacs?

  - by Peter

  I can move my pointer up and down one line with my arrow key just fine in Emacs, so I'd like to redefine C-n and C-p to move up and down 5 lines at a time. I'm just beginning to learn how to use Emacs, and elisp is very alien to me. I tried using the GNU Emacs lisp reference, but I couldn't find how to bind a keystroke to multiple commands. Here's what I have so far (concentrating on the moving up definition): (global-set-key "\C-p" '(loop for i in '(1 2 3 4 5) do ('previous-line))) But, this brings up an error message when I hit C-p, "Wrong type argument." Any suggestions? Thanks!

• How to enable absolute paths in LaTeX

  - by Matthias Günther

  Hey, I have one document under ~/my_files/test.tex and want to include in test.tex some styling informations, which can be found under ~/latex/styles/info_hypersetup.tex. When I include the following statement into my test.tex: %% setting the infos for the pdf \include{home/helex/latex/styles/info_hypersetup.tex} I get the following error when running pdflatex test.test: ! I can't write on file `~/latex/styles/info_hypersetup.tex.aux'. I set the rights to 777 but this doesn't changed anything. It works, if I put info_hypersetup.tex in the directory-structure where test.tex is. But I want to use this styleinformation as a global setting for all my documents and don't want to copy it into every project. Thanks for your help.

• File paths with XSLT includes

  - by Andrew Parisi

  Hi again everyone. I'm working on a website with a large number of pages, and each one has this in it: <xsl:include href="team-menu.xsl" /> This xsl file is stored in the root directory. Essentially including my "team menu" on each page. My problem is when I include this on nested pages, e.g. "/teammembers/smith.xsl", the links in the menu are broken because they refer to pages that aren't in the same directory as the page i'm viewing. This is probably really easy, but I just don't know how to fix it. Is there a way to tell the XSL the root directory and/or set some sort of global directory? Thanks for your help!

• How to refresh an activity?

  - by poeschlorn

  Hi Guys, after implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no Idea how to tell the map activity to refresh on its own and display the new coords... the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view? private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { final TextView tv = (TextView) findViewById(R.id.myTextView); if (loc != null) { tv.setText("Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude()); } } I think the solution of this Problem won't be very difficult, but I just need the beginning ;-) This whole app shall work like a really simple navigation system. It would be great if someone could help me a little bit further :) nice greetings, Poeschlorn

• In Windows 7, clicking between file explorer windows does not generate window events. What's up?

  - by asmw

  I have a custom made global hook installed and am monitoring for window messages when file explorer windows are clicked on. The funny thing is that they don't generate any window messages! I click between two file explorer windows and nothing. No VM_CREATE, no VM_ACTIVATE. Nothing. Why is this? Spy++ crashes on my machine so I can't use it but my hook is pretty good and should pick everything up. For some reason these windows just don't function like normal windows in that they don't generate the standard window messages when they become active. It seems windows 7 does not see them as normal windows? what's going on?

• use callback function to report stack backtrace

  - by user353394

  Assume I have the following: typedef struct { char *name; char binding; int address; } Fn_Symbol //definition of function symbol static Fn_Symbol *fnSymbols; //array of function symbols in a file statc int total; //number of symbol functions in the array and file static void PrintBacktrace(int sigum, siginfo_t * siginfo, void *context) { printf("\nSignal received %d (%s)\n", signum, strsignal(signum)); const int eip_index = 14; void *eip = (void *)((struct ucontext *)context)->uc_mcontext.gregs[eip_index]; printf("Error at [%p] %s (+0x%x), eip, fnName, offset from start); //????? exit(0); } I have this so far, but what is the best way using the fnSymbols static global pointer to identify the function where the error occured and then back trace through the stack to identify each calling function by address, name, and offset?

• release vs setting-to-nil to free memory

  - by Dan Ray

  In my root view controller, in my didReceiveMemoryWarning method, I go through a couple data structures (which I keep in a global singleton called DataManager), and ditch the heaviest things I've got--one or maybe two images associated with possibly twenty or thirty or more data records. Right now I'm going through and setting those to nil. I'm also setting myself a boolean flag so that various view controllers that need this data can easily know to reload. Thusly: DataManager *data = [DataManager sharedDataManager]; for (Event *event in data.eventList) { event.image = nil; event.thumbnail = nil; } for (WondrMark *mark in data.wondrMarks) { mark.image = nil; } [DataManager sharedDataManager].cleanedMemory = YES; Today I'm thinking, though... and I'm not actually sure all that allocated memory is really being freed when I do that. Should I instead release those images and maybe hit them with a new alloc and init when I need them again later?

• Can I prevent a user from using windows taskmanager to end a process?

  - by Russ

  I have a c# 4.0 application that I hear grumblings and rumors about problems with. Now, this application has a global unhandled exception handler that reports back to me with errors. I also know that it works because SOME people fill it in, and submit it. It seems though; that a large number of people do NOT fill it in, but instead, use the Windows Taskmanager to end the process. Is it possible to prevent a user from using the Windows Taskmanager to end a specific process? My goal would be that if the application crashes, the form that the user is presented with prevents the process from being ended. I'll also accept steps that would prevent the Windows Taskmanager from being launched.

• How do you create multiple versions of an ActiveX control?

  - by Peter Ruderman

  Hopefully this is a straightforward question, but googling has proved fruitless (and frustrating, to say the least). Links to good documentation would be greatly appreciated. Here's the problem. We have a web application with an associated ActiveX control. (The control wraps a crufty old MFC application if it matters.) Moving forward, we expect to release multiple versions of this application, and each will have a corresponding version of the control. If someone accesses two versions of the web application, then that user should end up with two different versions of the control on his system. (The controls should play nice and not clobber each other.) In addition, I want to automate this process. Our system has a global version number that applies to all components. If we change the version number, the next build should produce a new version of the control. What's the best way to do this?

• WordPress + Facebook comments addition (php knowledge needed)

  - by user1356223

  I succeded to fetch Facebok comments number via this function: <?php function fb_comment_count() { global $post; $url = get_permalink($post->ID); $filecontent = file_get_contents('https://graph.facebook.com/?ids=' . $url); $json = json_decode($filecontent); $count = $json->$url->comments; if ($count == 0 || !isset($count)) { $count = 0; } echo $count; } ;?> And I call it with: <?php fb_comment_count();?> Now how do I add it to this code: <?php comments_number(__('No Comments'), __('1 Comment'), __('% Comments'), '', __('Comments Closed') ); ?> so that WordPress shows number of WP and FB comments together in one number. Thank you very much to everyone!

• How can I include .pdf files when I publish but not in a search and replace in visual studio?

  - by Mike

  More specifically my problem is if I include a pdf in my project and set its build action to content so it gets copied to the server when I publish, is there a way to exclude it from visual studios search and replace feature. Would a post build action be a solution to this? I just don't want anybody to do a global search and replace in my project and mess up the pdfs... I know I just said a mouth full so let me know if you need clarification. Thanks!!!

• Do you know Best Practise and Design Patterns for Adobe Air/Flex Applications?

  - by Julian

  I'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch. For instance: I stumbled across lots of software written in Air/Flex with nearly infinity global vars :-) Most of the software I saw was not object-oriented How can I pack the asynchronous method calls nicely? I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.

• Finding final/effective web.config values (from inherited configurations)

  - by gregmac

  Are there any apps that can show the final configuration as applied to a particular application directory? What I'm picturing is something along the lines of FireBug's CSS viewer. Basically, it should show the equivalent single web.config file (as if you only had one), with all the values that apply to the directory in question, with each element (or even attribute) annotated with its source (the real .config file it came from). This would greatly help deploying applications into foreign environments (eg, customer sites) where they sometimes have strange configs, that add in global includes (eg, they put the include in machine.config, instead of the web.config for that app) or have allowOverride=false, etc.

• PHP code in Drupal 6

  - by abhishekgupta92

  A very standard example of the problem that I am facing is that of a custom content say blog type. Now there is a view namely "My Blog Posts". In that view i take the argument as User:uid. Now, for the link part i simply write the code below: global $user; and send $user-uid as the argument to User:Uid. This give me link for "My Blog Posts" or the blog posts of the logged-in user What I want is a view like "His Blog Posts". So, if i visit the profile of some other user. There should be a tab in his profile "Blog Posts by Me". So for that i need to have the UID of the user whose profile I am visiting. So, how can I get this parameter from URL of his profile or somevhere else.

• Drawing random circles

  - by ViktorC

  I am trying to draw a cupola circles at random positions in an Android application. I draw them on a bitmap and then draw that bitmap on the canvas. This is the function where a draw the circles: private void drawRandomCircles(int numOfCircles) { Canvas c = new Canvas(b); Paint cPaint = new Paint; cPaitn.setColor(Color.RED); for(int i = 0; i < numOfCircles; i++) { int x = Math.Random % 100; int y = Math.Random % 100; c.drawCircle(x, y, 20, cPaint) } } The Bitmap b is global. And after calling this function I just draw the bitmap in the onDraw method. Now the problem is that I only get one circle drawn on the screen, no matter the size of numOfCircles. Any clue what is happening here?

• Pass errors in Django using HttpResponseRedirect

  - by JPC

  I know that HttpResponseRedirect only takes one parameter, a URL. But there are cases when I want to redirect with an error message to display. I was reading this post: How to pass information using an http redirect (in Django) and there were a lot of good suggestions. I don't really want to use a library that I don't know how works. I don't want to rely on messages which, according to the Django docs, is going to be removed. I thought about using sessions. I also like the idea of passing it in a URL, something like: return HttpResponseRedirect('/someurl/?error=1') and then having some map from error code to message. Is it good practice to have a global map-like structure which hard codes in these error messages or is there a better way? Or should I just use a session EDIT: I got it working using a session. Is that a good practice to put things like this in the session?

• Ruby class variable is reset after rails app initialized

  - by Phuong Nguy?n

  I tried to assign a class static variable like this class QueryLogger < Logger @@query_logger_default_instance = nil def self.default_instance # Use global variable because static variable doesn't work @@query_logger_default_instance ||= self.new(STDOUT) end end In initializers folder of my rails app, I added a file with this code block ActiveRecord::Base.logger = QueryLogger.default_instance In a request (action of controller), I make a call to this: QueryLogger.default_instance. My assumption is that the call to default_instance will always report the same. However, it does not. Now I try to watch stuff in NetBeans by setting breakpoint inside default_instance. Thing happen as expected, the default_instance get called twice, one due to the initializer block and one due to the call to my action. Surprising thing is, in both times, @@query_logger_default_instance report nil inside NetBeans inspector. The first nil report is correct, but the second shocked me. It's look like static variable gets reset after rails app initialized. Is there some magic there?

• C++ option/long option implementation

  - by K Hein

  I am working on a parser for meta programming language using C++ on Linux platform. Right now, I need to implement option/long option for the parser to provide some additional features. Basically, if the user pass in some additional option, the parser needs to store statistics while parsing the text files. I can think of two ways to implement it. One way is to user global to store options entered by users. Another way is to create a singleton class to store options. So I would like to know if there is any other way to implement it. What is the best/most recommended way of implementing it? Thanks in advance. Regards, K.Hein

• Confused about GNU `sort(1)` of a numerical sub field

  - by Chen Levy

  I wish to sort a space separated table, with the numerical value that found on the 2nd field. I can assume that the 2nd field is always fooN but the length of N is unknown: antiq. foo11 girls colleaguing foo2 Leinsdorf Cousy foo0 Montgomeryville bowlegged foo1 pollack Chevrier foo10 ill-conceived candlebomb foo3 seventieths autochthony foo101 re-enable beneficiate foo100 osteometric I read man sort(1) and played with all sort of options. On my system I found the line: sort -n -k2.5 table to work. My question is why? According to the man page: -k, --key=POS1[,POS2] start a key at POS1, end it at POS 2 (origin 1) ... POS is F[.C][OPTS], where F is the field number and C the characterposition in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key. So why sort -n -k2.4 table don't work and sort -n -k.5 does?

• Why are closures broken within exec?

  - by Devin Jeanpierre

  In Python 2.6, >>> exec "print (lambda: a)()" in dict(a=2), {} 2 >>> exec "print (lambda: a)()" in globals(), {'a': 2} Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<string>", line 1, in <module> File "<string>", line 1, in <lambda> NameError: global name 'a' is not defined >>> exec "print (lambda: a).__closure__" in globals(), {'a': 2} None I expected it to print 2 twice, and then print a tuple with a single cell. It is the same situation in 3.1. What's going on?

• Finding the right version of the right JAR in a maven repository

  - by Matt McHenry

  I'm converting a build that has 71 .jar files in its global lib/ directory to use Maven. Of course, these have been pulled from the web by lots of developers over the past ten years of this project's history, and weren't always added to VCS with all the necessary version info, etc. Is there an easy, automated way to go from that set of .jar files to the corresponding <dependency/> elements for use in my pom.xml files? I'm hoping for a web page where I can submit the checksum of a jar file and get back an XML snippet. The google hits for 'maven repository search' are basically just finding name-based searches. And http://repo1.maven.org/ has no search whatsoever, as far as I can see. Update: GrepCode looks like it can find projects given an MD5 checksum. But it doesn't provide the particular details (groupId, artifactId) that Maven needs.

• writing to a file in nasm using system calls

  - by yurib

  As part of an assignment I'm supposed to write to a file using system calls. Everything works fine except when I try to open the file in gedit (linux), it says it can't identify the character encoding. Notepad (on windows) opens the file just fine. Why doesn't it work on linux ? here's the code: section .text global _start _start: mov EAX, 8 mov EBX, filename mov ECX, 0700 int 0x80 mov EBX, EAX mov EAX, 4 mov ECX, text mov EDX, textlen int 0x80 mov EAX, 6 int 0x80 mov eax, 1 int 0x80 section .data filename db "./output.txt", 0 text db "hello world", 0 textlen equ $ - text thanks :)
