  • Metadata file ... could not be found error when building projects

    - by Robert Höglund
    Every time I start Visual Studio 2008, the first time I try to run the project I get the error CS0006 The metadata file ... could not be found. If I do a rebuild of the complete solution it works. Some information about the solution: I'm building in debug mode and Visual Studio complains about not finding dll:s in the release folder. The projects Visual Studio complains about are used by many other projects in the solution. I have changed the default output path of all projects to a ......\build\debug\ProjectName and ......\build\release\ProjectName respectively. (Just to get all build files in one directory) I have the same problem with a another solution. The solution was created from scratch. There are 9 projects in the solution. One WPF and 8 class libraries using dotnet 3.5. Any ideas on what is causing this problem?

  • MATLAB Magical Mystery timing behavior

    - by Jacob Lyles
    I am experiencing some very odd timing behavior from a function I wrote. If I wrap my function inside another empty container function, it gets a 3x speedup. > tic; foo(args); toc time elapsed: ~140 seconds >tic; bar(args); toc time elapsed: ~35 seconds Here's the kicker - the definition of bar(): define bar(args) foo(args) end Is there some sort of optimization that gets triggered in MATLAB for nested function calls? Should I be adding a dummy function to every function that I write?

  • how to order a group result with Linq?

    - by Aaron
    How can I order the results from "group ... by... into..." statement in linq? For instance: var queryResult = from records in container.tableWhatever where records.Time >= DateTime.Today group records by tableWhatever.tableHeader.UserId into userRecords select new { UserID = userRecords.Key, Records = userRecords }; The query returns records in table "contain.tableWhatever" grouped by "UserId". I want the returned results within each group ordered by time decending. How can I do that? More specific, assume the above query return only one group like the following: {UserID = 1, Records= {name1 5/3/2010_7:10pm; name2 5/3/2010_8:10pm; name3 5/3/2010_9:10pm} } After insert the orderby statement in the above query, the returned results should be like this: {UserID = 1, Records= {name3 5/3/2010_9:10pm; name2 5/3/2010_8:10pm; name1 5/3/2010_7:10pm} } Thanks for help!

  • Where can I find a proper JavaScript beautifier

    - by Ernelli
    I have used http://jsbeautifier.org/ successfully using Rhino and ant, but the problem is that it is not deterministic. If you run the beautifier twice on a file the result is different from each time, e.g. each pass inserts additional array intendation on some lines. I have spent a lot of time debugging the code in beautify.js and have made some workarounds for comment handling, but the array indentation bug is annoying. Is there a correct and properly working JS code formatter anywhere that can be used as part of a source code indentation verification system? EDIT I have now tested with preserve-array-formating disabled, and it seems that it solves the problem. Too bad, since preserve-array-formating is quite useful with large array constructs.

  • Has anyone noticed that a WPF file dialog will pass through a click to the UI when double clicking t

    - by Ben
    I have some buttons on my WPF UI and I also need to choose files from time to time. I kept noticing strange problems where when I double-click an item in the file dialog, a button on the main UI would also get clicked. After experimenting, it seems that if you line up an item in the file dialog with a button behind it on the main UI and double click to select the file, it will single-click the button behind it as well. Has anyone else noticed this, or is it just a freak bug with the way I have my UI laid out?

  • Rails send mail with GMail

    - by Danny McClelland
    Hi Everyone, I am on rails 2.3.5 and have the latest Ruby installed and my application is running well, except, GMail emails. I am trying to setup my gmail imap connection which has worked previously but now doesnt want to know. This is my code: # Be sure to restart your server when you modify this file # Uncomment below to force Rails into production mode when # you don't control web/app server and can't set it the proper way # ENV['RAILS_ENV'] ||= 'production' # Specifies gem version of Rails to use when vendor/rails is not present RAILS_GEM_VERSION = '2.3.5' unless defined?

I have read varied reports of this not working in Rails 2.2.2 but nothing for 2.3.5, anyone got any ideas? Thanks, Danny

  • Indexing large DB's with Lucene/PHP

    - by thebluefox
    Afternoon chaps, Trying to index a 1.7million row table with the Zend port of Lucene. On small tests of a few thousand rows its worked perfectly, but as soon as I try and up the rows to a few tens of thousands, it times out. Obviously, I could increase the time php allows the script to run, but seeing as 360 seconds gets me ~10,000 rows, I'd hate to think how many seconds it'd take to do 1.7million. I've also tried making the script run a few thousand, refresh, and then run the next few thousand, but doing this clears the index each time. Any ideas guys? Thanks :)

  • Creating a custom widget using django for use on external sites

    - by ajt
    I have a new site that I am putting together and part of it has statistics for the site's users. I would like to create a widget that others can use on another website by invoking javascript that reads data from my server and shows that statistics for a given user, but I am having a hard time finding specific tutorials that covers this in django. I have seen the link at Alex Maradon's site [0], but it looks to me like that is passing html back to the widget and I am having a hard time figuring out how to do this using something like xml. Are there any django apps for doing this or does anyone know of good how-tos? [0] http://alexmarandon.com/articles/web_widget_jquery/

  • Best way to do something when a runloop event is done processing?

    - by quixoto
    I have some processing in my Cocoa app that sometimes ends up calling through a hierarchy of data to do a bunch of work as the result of an event. Each small piece creates and destroys some resources. I don't want those resources around most of the time, but I would like to find a smart way of creating them before all the work and killing them at the end. Short of creating the resources up front and then passing them entirely down through the call hierarchy when work is done, is there a way to know locally in some code when an event loop run has ended? Then I could create them if they're not there, and keep them until the run loop ends, reusing them for any subsequent calls before that time. Thanks.

  • Selenium WebDriver works but SLOW (Java)

    - by Chris
    Code: WebDriver driver = new FirefoxDriver(); driver.get("http://www.cnn.com"); File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File("c:\\test\\screenshot.png")); I am using Selenium WebDriver to take a screenshot of webpages. It runs great. However, from the time I hit run in eclipse to the time the screenshot shows up in my local drive is 7-10 seconds. Most of the latency seems to be launching Firefox. How can I speed up this process? Is there a way that I can use an already opened Firefox browser to save on opening a new one? Is this code somehow heavy? Details- Tried on CentOS box and Win7 box both using eclipse. myspeedtest.net shows 22Mbps down and 1 Mbps up.

  • Dynamic instant theming a la My Yahoo / iGoogle

    - by Alex Neth
    I can think of lots of ways to do this on my own, but I was hoping to find some sort of best practice and have been having trouble finding other's experiences. I want to create easily themed HTML and provide a real-time selector for the user to experiment with themes. I want to do something like the "Change Appearance" tab at http://my.yahoo.com . I'll be using jQuery. jQuery has a "theming" system, but it seems very much focused on jQuery widgets as opposed to the whole site, and also doesn't appear to address the real-time selection aspect (the jQuery page has this functionality, but I don't think it's part of the library.) Maybe there is a jQuery plugin that already does this? Or some sort of css/jQuery framework?

  • Code snippets in interview

    - by Maddy
    Hi All, Recently I went to an interview for a C development position. Instead of asking me questions, they just gave me 20 code snippets to find out two logical errors on each one. I just couldn't complete all of the 20 since it took me time to go through each of these code snippets. My question is: Is this the right way to judge a candidate? If yes, how can I improve over my error detection skills so that I don't need to waste a lot of time in the next interview? If possible, please, suggest me some links where I could find lots of samples of such questions (mainly in C). Thanks and regards, Maddy

  • Speed up multiple JDBC SQL querys?

    - by paddydub
    I'm working on a shortest path a* algorithm in java with a mysql db. I'm executing the following SQL Query approx 300 times in the program to find route connections from a database of 10,000 bus connections. It takes approx 6-7 seconds to execute the query 300 times. Any suggestions on how I can speed this up or any ideas on a different method i can use ? Thanks ResultSet rs = stmt.executeQuery("select * from connections" + " where Connections.From_Station_stopID ="+StopID+";"); while (rs.next()) { int id = rs.getInt("To_Station_id"); String routeID = rs.getString("To_Station_routeID"); Double lat = rs.getDouble("To_Station_lat"); Double lng = rs.getDouble("To_Station_lng"); int time = rs.getInt("Time"); }

  • I want to use VI-like commands in Web Browser?

    - by Frank
    I love VI and I'm looking for a plugin of some sort that would allow me to input text in my browser (preferably Firefox or Chrome) using VI commands. It would save me an immense amount of time and at the same time when writing long emails. Can anyone think of any plugins that would allow me to do this? I was hopeful with Vimperator (https://addons.mozilla.org/en-US/firefox/addon/4891) but after installing it, I realized that it didn't do the one VI think I wanted to do: create or edit a text box with VI commands. It just allowed me to do Browser commands and scrolling in VI-style.

  • php download file slows

    - by hobbywebsite
    OK first off thanks for your time I wish I could give more than one point for this question. Problem: I have some music files on my site (.mp3) and I am using a php file to increment a database to count the number of downloads and to point to the file to download. For some reason this method starts at 350kb/s then slowly drops to 5kb/s which then the file says it will take 11hrs to complete. BUT if I go directly to the .mp3 file my browser brings up a player and then I can right click and "save as" which works fine complete download in 3mins. (Yes both during the same time for those that are thinking it's my connection or ISP and its not my server either.) So the only thing that I've been playing around with recently is the php.ini and the .htcaccess files. So without further ado, the php file, php.ini, and the .htcaccess: download.php <?php include("config.php"); include("opendb.php"); $filename = 'song_name'; $filedl = $filename . '.mp3'; $query = "UPDATE songs SET song_download=song_download+1 WHER song_linkname='$filename'"; mysql_query($query); header('Content-Disposition: attachment; filename='.basename($filedl)); header('Content-type: audio/mp3'); header('Content-Length: ' . filesize($filedl)); readfile('/music/' . $filename . '/' . $filedl); include("closedb.php"); ?> php.ini register_globals = off allow_url_fopen = off expose_php = Off max_input_time = 60 variables_order = "EGPCS" extension_dir = ./ upload_tmp_dir = /tmp precision = 12 SMTP = relay-hosting.secureserver.net url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset=" ; Defines the default timezone used by the date functions date.timezone = "America/Los_Angeles" .htaccess Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} !^(www.MindCollar.com)?$ [NC] RewriteRule (.*) http://www.MindCollar.com/$1 [R=301,L] <IfModule mod_rewrite.c> RewriteEngine On ErrorDocument 404 /errors/404.php ErrorDocument 403 /errors/403.php ErrorDocument 500 /errors/500.php </IfModule> Options -Indexes Options +FollowSymlinks <Files .htaccess> deny from all </Files> thanks for you time

  • What is the best approach to write test cases using sentestinkit in iPhone / iPad ?

    I am developing an application for iPad application. I need to perform unit testing in the application, but I am not sure why I should do unit testing in this application. Edit: And since the iPhone SenTestingKit is not well documented, the implementation and writing test cases is so time consuming. So why should we waste time with this? Also if we have to what would be the best approach to write the test cases? My focus is on the second question. So please answer more for the second part, I would be very pleased.

  • Which has been the most reliable, fastest Windows C++ profiler that you have used?

    - by carleeto
    I need to profile a real time C++ app on Windows. Most of the available profilers are either terribly expensive, total overkill, or both. I don't need any .NET stuff. Since it is a real time app, I need the profiler to be as fast as possible. It would be excellent if it integrated in some way with Visual Studio 2005/2008, but that's not necessary. If this description reminds you of a profiler that you have used, I would really like to know about it. I am hoping to draw from people's use of C++ profilers on Windows to pinpoint one that will do the job. Thanks.

  • Where are the really high quality and complex Swing components?

    - by jouhni
    Looking at Swing, I have the feeling that it comes with many useful and reasonable atomic components in its core. And when I look at the Web there are hundrets of quickly plugged together components (among them many date/time pickers, pimped lists and tables), which have in common that I could easily write them on my own, if I needed them. When I build big software and come to the point where I need a domain-specific component which is really big, I mostly come to the point where I have to write it on my own, which, due to the point that they are not just plugged together lists and tables, isn't done qickly. So, the question is, why are there no Swing component galleries which contain more than just customized date/time pickers or lists with added tree support. Where are the components which really raise the level of abstraction, or are in best case domain-specific?

  • Qt compilation and stylesheet

    - by Yosko
    Each time I compile my Qt project after modifying my qss stylesheet file, the modifications aren't taken into account, unless I rebuild everything. Any idea on a workaround for this, so that I don't have to wait 5 minutes each time I change my qss ? Notes: I use Qt 4.8, and my stylsheet is declared in a resource file (qrc). EDIT: As suggested by Luca Carlon, when a qss is reference in the project through a .qrc file, the changes in the qss don't affect the qrc, and the compiler ignores it. To avoid that, I added a Custom Build Step to my project: before the qmake step! calls a .bat file without any argument the .bat contains the real command copy /b files.qrc +,,

  • How to handle environment-specific application configuration organization-wide?

    - by Stuart Lange
    Problem Your organization has many separate applications, some of which interact with each other (to form "systems"). You need to deploy these applications to separate environments to facilitate staged testing (for example, DEV, QA, UAT, PROD). A given application needs to be configured slightly differently in each environment (each environment has a separate database, for example). You want this re-configuration to be handled by some sort of automated mechanism so that your release managers don't have to manually configure each application every time it is deployed to a different environment. Desired Features I would like to design an organization-wide configuration solution with the following properties (ideally): Supports "one click" deployments (only the environment needs to be specified, and no manual re-configuration during/after deployment should be necessary). There should be a single "system of record" where a shared environment-dependent property is specified (such as a database connection string that is shared by many applications). Supports re-configuration of deployed applications (in the event that an environment-specific property needs to change), ideally without requiring a re-deployment of the application. Allows an application to be run on the same machine, but in different environments (run a PROD instance and a DEV instance simultaneously). Possible Solutions I see two basic directions in which a solution could go: Make all applications "environment aware". You would pass the environment name (DEV, QA, etc) at the command line to the app, and then the app is "smart" enough to figure out the environment-specific configuration values at run-time. The app could fetch the values from flat files deployed along with the app, or from a central configuration service. Applications are not "smart" as they are in #1, and simply fetch configuration by property name from config files deployed with the app. The values of these properties are injected into the config files at deploy-time by the install program/script. That install script takes the environment name and fetches all relevant configuration values from a central configuration service. Question How would/have you achieved a configuration solution that solves these problems and supports these desired features? Am I on target with the two possible solutions? Do you have a preference between those solutions? Also, please feel free to tell me that I'm thinking about the problem all wrong. Any feedback would be greatly appreciated.

  • Leak caused by fread

    - by Jack
    I'm profiling code of a game I wrote and I'm wondering how it is possible that the following snippet causes an heap increase of 4kb (I'm profiling with Heapshot Analysis of Xcode) every time it is executed: u8 WorldManager::versionOfMap(FILE *file) { char magic[4]; u8 version; fread(magic, 4, 1, file); <-- this is the line fread(&version,1,1,file); fseek(file, 0, SEEK_SET); return version; } According to the profiler the highlighted line allocates 4.00Kb of memory with a malloc every time the function is called, memory which is never released. This thing seems to happen with other calls to fread around the code, but this was the most eclatant one. Is there anything trivial I'm missing? Is it something internal I shouldn't care about? Just as a note: I'm profiling it on an iPhone and it's compiled as release (-O2).
