  • The system cannot find the path specified with FileWriter

    - by Nazgulled
    Hi, I have this code: private static void saveMetricsToCSV(String fileName, double[] metrics) { try { FileWriter fWriter = new FileWriter( System.getProperty("user.dir") + "\\output\\" + fileTimestamp + "_" + fileDBSize + "-" + fileName + ".csv" ); BufferedWriter csvFile = new BufferedWriter(fWriter); for(int i = 0; i < 4; i++) { for(int j = 0; j < 5; j++) { csvFile.write(String.format("%,10f;", metrics[i+j])); } csvFile.write(System.getProperty("line.separator")); } csvFile.close(); } catch(IOException e) { System.out.println(e.getMessage()); } } But I get this error: C:\Users\Nazgulled\Documents\Workspace\Só Amigos\output\1274715228419_5000-List-ImportDatabase.csv (The system cannot find the path specified) Any idea why? I'm using NetBeans on Windows 7 if it matters...

  • Performance optimization strategies of last resort?

    - by jerryjvl
    There are plenty of performance questions on this site already, but it occurs to me that almost all are very problem-specific and fairly narrow. And almost all repeat the advice to avoid premature optimization. Let's assume: the code already is working correctly the algorithms chosen are already optimal for the circumstances of the problem the code has been measured, and the offending routines have been isolated all attempts to optimize will also be measured to ensure they do not make matters worse What I am looking for here is strategies and tricks to squeeze out up to the last few percent in a critical algorithm when there is nothing else left to do but whatever it takes. Ideally, try to make answers language agnostic, and indicate any down-sides to the suggested strategies where applicable. I'll add a reply with my own initial suggestions, and look forward to whatever else the SO community can think of.

  • Visual Studio bug ~ 1 verified repro, 1 verified non-repro, any others?

    - by drachenstern
    In Visual Studio 2010 Pro (Version 10.0.30319.1 RTMRel), I noticed tonight that for some reason I kept getting a wider window for quick find, but thought I was losing my mind. So I exited, restarted, etc to verify. Here's my repro steps Open existing project (I don't think it matters which one) Press ctrlf and give it something to search for (?) in "current document" Press enter Press ctrlf Press enter goto 4 Can you reproduce a slowly expanding quick find window? Do I have some sort of wacky bugged out system? I'ld obviously like to submit a bug report to MS if this is indeed a viable repro.

  • mongodb php finding a subobject and removing it, $inc other subobject

    - by Mark
    I'm trying to delete the subobject 'apples' from my documents and update the 'fruitInventory' property, decrease by the amount of apples. I'm confused on how to proceed, should I use dot notation or do a full text search for apples? I don't know if this matters but you can assume apples will always be in field 1. // Document 1 { "1": { "apples": 3, "fruitInventory": 21, "oranges": 12, "kiwis": 3, "lemons": 3 }, "2": { "bananas": 4, "fruitInventory": 12, "oranges": 8, }, "_id": "1" } // Document 2 { "1": { "apples": 5, "fruitInventory": 10, "oranges": 2, "pears": 3 }, "2": { "bananas": 4, "fruitInventory": 6, "cherries": 2, }, "_id": "2" } Result should be like this: // Document 1 { "1": { "fruitInventory": 18, "oranges": 12, "kiwis": 3, "lemons": "3" }, "2": { "bananas": 4, "fruitInventory": 12, "oranges": 8, }, "_id": "1" } // Document 2 { "1": { "fruitInventory": 5, "oranges": "2", "pears": "3" }, "2": { "bananas": 4, "fruitInventory": 6, "cherries": 2, }, "_id": "2" } Thanks in advance for your help.

  • How should I handle incomplete packet buffers?

    - by Benjamin Manns
    I am writing a client for a server that typically sends data as strings in 500 or less bytes. However, the data will occasionally exceed that, and a single set of data could contain 200,000 bytes, for all the client knows (on initialization or significant events). However, I would like to not have to have each client running with a 50 MB socket buffer (if it's even possible). Each set of data is delimited by a null \0 character. What kind of structure should I look at for storing partially sent data sets? For example, the server may send ABCDEFGHIJKLMNOPQRSTUV\0WXYZ\0123!\0. I would want to process ABCDEFGHIJKLMNOPQRSTUV, WXYZ, and 123! independently. Also, the server could send ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890LOL123HAHATHISISREALLYLONG without the terminating character. I would want that data set stored somewhere for later appending and processing. Also, I'm using asynchronous socket methods (BeginSend, EndSend, BeginReceive, EndReceive) if that matters.

  • How to select nth element of particular type in enlive?

    - by Mad Wombat
    I am trying to scrape some data from a page with a table based layout. So, to get some of the data I need to get something like 3rd table inside 2nd table inside 5th table inside 1st table inside body. I am trying to use enlive, but cannot figure out how to use nth-of-type and other selector steps. To make matters worse, the page in question has a single top level table inside the body, but (select data [:body : :table]) returns 6 results for some reason. What the hell am I doing wrong?

  • How does one go about understanding GNU source code?

    - by Max Dwayne
    I'm really sorry if this sounds kinda dumb. I just finished reading K&R and I worked on some of the exercises. This summer, for my project, I'm thinking of re-implementing a linux utility to expand my understanding of C further so I downloaded the source for GNU tar and sed as they both seem interesting. However, I'm having trouble understanding where it starts, where's the main implementation, where all the weird macros came from, etc. I have a lot of time so that's not really an issue. Am I supposed to familiarize myself with the GNU toolchain (ie. make, binutils, ..) first in order to understand the programs? Or maybe I should start with something a bit smaller (if there's such a thing) ? I have little bit of experience with Java, C++ and python if that matters. Thanks!

  • Integrate test process with Rspec and Cucumber in a plugin using Desert

    - by Romain Endelin
    Hello, I'm developing some rails plugins with desert, and I would like to use tests with RSpec and Cucumber in the development. RSpec is integrated by default in Desert plugins, but it gives me some bugs. Finally I have created a minimal application which use my plugin, and I try to test it like a normal application without plugin. But I dislike that solution, the plugin lost its modularity, and RSpec still returns me some bugs (he can't find the models/views/controllers located in the plugin...). So am I the only one who try to test a Desert plugin (or even in a classic plugin) ? May anyone know those matters and get a solution ?

  • ADO "Unspecified Error" instead of actual error when fetching server side cursor

    - by Dan
    This relates to my recent question: http://stackoverflow.com/questions/2835663/force-oracle-error-on-fetch I am now able to reproduce a scenario where using ADO with the Oracle OLEDB Provider, I can force an error such as ORA-01722: invalid number to occur on calling Recordset.MoveNext However, this is not the error that is returned to the application. Instead, the application sees Provider error '80004005' Unspecified error. How can I get the application to see the real error from the database? This is with Oracle 10g (client and server), if it matters. Sample code is roughly as follows: Dim con As New ADODB.Connection Dim cmd As New ADODB.Command Dim rs As ADODB.Recordset con.ConnectionString = "Provider=OraOLEDB.ORACLE;Data Source=xxx;User Id=yyy;Password=zzz" con.CursorLocation = adUseServer con.Open Set cmd.ActiveConnection = con cmd.CommandText = "select * from table(ret_err)" cmd.Prepared = True Set rs = cmd.Execute While Not rs.EOF rs.MoveNext Wend

  • VBA Tab Key putting actual Tab Value in Text Box instead of navigating to next control

    - by ray023
    I have a VBA form (in Excel if that matters) that contains text boxes. On three occasions, I have found myself pressing the tab key to navigate to the next control, but instead an actual TAB is being put in the text box. The form normally acts as it should, but it does concern me that this gremlin is showing up sporadically. It has shown up on Office 2003 as well as Office 2007 on two different computers. Has anyone else encountered this problem and, if so, how did you fix it?

  • sql server datetime

    - by cvista
    hey i have the following query: select * from table where table.DateUpdated >='2010-05-03 08:31:13:000' all the rows in the table being queried have the following DateUpdated: 2010-05-03 08:04:50.000 it returns all of the rows in the table - even though it should return none. I am pretty sure this is because of some crappy date/time regional thing. if i swap the date to be select * from table where table.DateUpdated >='2010-03-05 08:31:13:000' then it does as it should. How can i force everything to be using the same settings? this is doing my head in :) This is sql generated by NHIbernate from my WCF service if that matters. w://

  • etree.findall: 'OR'-lookup?

    - by piquadrat
    I want to find all stylesheet definitions in a XHTML file with lxml.etree.findall. This could be as simple as elems = tree.findall('link[@rel="stylesheet"]') + tree.findall('style') But the problem with CSS style definitions is that the order matters, e.g. <link rel="stylesheet" type="text/css" href="/media/css/first.css" /> <style>body:{font-size: 10px;}</style> <link rel="stylesheet" type="text/css" href="/media/css/second.css" /> if the contents of the style tag is applied after the rules in the two link tags, the result may be completely different from the one where the rules are applied in order of definition. So, how would I do a lookup that inlcudes both link[@rel="stylesheet"] and style?

  • Linq to SQL gives NotSupportedException when using local variables

    - by zwanz0r
    It appears to me that it matters whether you use a variable to temporary store an IQueryable or not. See the simplified example below: This works: List<string> jobNames = new List<string> { "ICT" }; var ictPeops = from p in dataContext.Persons where ( from j in dataContext.Jobs where jobNames.Contains(j.Name) select j.ID).Contains(p.JobID) select p; But when I use a variable to temporary store the subquery I get an exception: List<string> jobNames = new List<string> { "ICT" }; var jobs = from j in dataContext.Jobs where jobNames.Contains(j.Name) select j.ID; var ictPeops = from p in dataContext.Persons where jobs.Contains(p.JobID) select p; "System.NotSupportedException: Queries with local collections are not supported" I don't see what the problem is. Isn't this logic that is supposed to work in LINQ?

  • Reverting CoreData data

    - by ndg
    I have an NSTableView which is populated via a CoreData-backed NSArrayController. Users are able to edit any field they choose within the NSTableView. When they select the rows that they have modified and press a button, the data is sent to a third-party webservice. Provided the webservice accepts the updated values, I want to commit those values to my persistent store. If, however, the webservice returns an error (or simply fails to return), I want the edited fields to revert to their original values. To complicate matters, I have a number of other editable controls, backed by CoreData, which do not need to resort to this behaviour. I believe the solution to this problem revolves around the creation of a secondary Managed Object context, which I would use only for values edited within that particularly NSTableView. But I'm confused as to how the two MOC would interact with each other. What's the best solution to this problem?

  • Why can't I see any data in the Google App Engine *Development* Console?

    - by willem
    I run my google app engine application in one of two ways... Directly by using the application from http://localhost:8080 Or execute unit tests from http://localhost:8080/test When I create entities by using the application directly, the data is visible in the Development Console (dataStore view). However, when I execute the unit tests... even if they succeed and I can put() and get() data, the data does not show in the dataStore view. Any idea why I can't see my data? Even though it is there? Notes: I use GAEUnit for unit tests. the data stored mostly consists of StringProperties(). I use Python and run Django on top of the GAE, don't know if that matters.

  • Sandcastle setup - Navigation to webpage was canceled.

    - by Prof Plum
    I am try to use Sandcastle Help File Builder, but can't quite get it to work. Here is what I have done: 1) installed the program; works like normal 2) enabled xml in the project I want documentation for that gets generated in the /bin 3) created a new sandcastle help file project 4) added the C# project as (its a WCF service in case that matters) a documentation service 5) ran the "build" to generate the help file 6) went to "documentation"/"view help file"/"view help file" in the GUI 7) The file opens and contains the appopriate "folders", but every page says "Navigation to the webpage was canceled" I have seen the xml file in the /bin and it contains all of my /// comments, so why are they not showing up in the help file? Any ideas?

  • How can I handle maxRequestLength exceptions elegantly?

    - by JMP
    In my ASP.NET MVC (v2 if it matters) app, I have a page that allows the user to upload a file. I've configured the maxRequestLength for my app to allow files up to 25MB. As a test, I send it a 500MB file which throws the exception: Maximum request length exceeded. (I only know this because ELMAH catches the error and logs it.) In my web.config, I've set customErrors mode="On" with a defaultRedirect, but the user isn't redirected at all, they don't even get a yellow-screen-of-death. In Chrome, for example, you'll see the error: Error 101 (net::ERR_CONNECTION_RESET): Unknown error. Is it possible to provide a more elegant user experience for this situation?

  • How can I create an .xls file with a readwrite password from Delphi

    - by dummzeuch
    I know that it is possible to create .xls files from Delphi using ADO, OLE automation with Excel and even using several commercial libraries. My requirement now is not just creating a new .xls file and adding data to it but in addition protecting it with a password against editing. I guess this would be possible using OLE automation but that would require an Excel installation on the computer and also add all the potential hassle of OLE automation which I would like to avoid. Does any of the other solutions provide the option of password protecting the file? (Yes, I know this is far from secure, but the customer requests it. Just in case it matters: I am using Delphi 2007.)

  • Artificially create a connection timeout error

    - by Mark Ingram
    I've had a bug in our software that occurs when I receive a connection timeout. These errors are very rare (usually when my connection gets dropped by our internal network). How can I generate this kind of effect artificially so I can test our software? If it matters the app is written in C++/MFC using CAsyncSocket classes. Edit: I've tried using a non-existant host, and I get the socket error: WSAEINVAL (10022) Invalid argument My next attempt was to use Alexander's suggestion of connecting to a different port, e.g. 81 (on my own server though). That worked great. Exactly the same as a dropped connection (60 second wait, then error). Thank you!

  • Emacs/xterm color annoyance on Linux

    - by tgamblin
    I'm using emacs in a console window both on my local Linux box and on the login node of a remote cluster. I use emacs regularly, and I've got the foreground color set to white in my .emacs file like so: (set-foreground-color "white") (set-background-color "black") However, when I run emacs, the foreground isn't white; it's grey and very hard to read. On my Mac, emacs in a console window with the same settings shows up as proper white. But on both linux boxes, in konsole and xterm, it's grey. In case it matters, I've got TERM set to xterm-color, the desktop is running RHEL 5, and the cluster node is running RHEL 4 (CentOS). Is this some default with how Linux sets up terminal colors? How do I get white to be white? Note: this is with console emacs, not emacs under X. That's emacs -nw if you have DISPLAY set.

  • TFS 2012 fresh install on fresh Windows Server 2008 warning that reporting services are not installed

    - by jshin47
    I am attempting to evaluate TFS 2012 for our organization but cannot seem to get past the first step of configuring the server using the "Standard Single Server" configuration wizard. In particular, in the service account selection screen, I am warned that: Reporting services are not installed on this computer. You need to install Reporting Services to complete TFS installation with this wizard. This is disheartening because the way I understand it, this should have been installed with the default TFS installation (in fact, no installation options are even provided) and this is a fresh and up-to-date Windows Server 2008 VM. I know I could install SQL Server 2008 or 2012 from MSDN, but shouldn't this work "out of the box?" I'd really rather use the default, small, integrated version of SQL Server that comes with TFS 2012 rather than rolling my own. If it matters, this server is joined to a domain and I am running TFS installation wizard as a domain administrator.

  • str_replace() with associative array

    - by Qiao
    You can use arrays with str_replace(): $array_from = array ('from1', 'from2'); $array_to = array ('to1', 'to2'); $text = str_replace ($array_from, $array_to, $text); But what if you have associative array? $array_from_to = array ( 'from1' => 'to1'; 'from2' => 'to2'; ); How can you use it with str_replace()? Speed matters - array is big enough.

  • PHP Linefeeds (\n) Not Working

    - by dosboy
    For some reason I can't use \n to create a linefeed when outputting to a file with PHP. It just writes "\n" to the file. I've tried using "\\n" as well, where it just writes "\n" (as expected). But I can't for the life of me figure out why adding \n to my strings isn't creating new lines. I've also tried \r\n but it just appends "\r\n" to the line in the file. Example: error_log('test\n', 3, 'error.log'); error_log('test2\n', 3, 'error.log'); Outputs: test\ntest2\n Using MAMP on OSX in case that matters (some sort of PHP config thing maybe?). Any suggestions?

  • PHP & MySQLi timeout

    - by Dt7
    Whenever I try to create a mysqli object, as in; $mysqli = new mysqli(host, user, pass, table); ...the page just loads for around a minute, then stops, showing all the content of the page up until that line. info() says that MySQLi (and MySQL if that matters) are enabled, and I can access the MySQL CLI. I'm also working on a local machine, not a remote server. I feel like I've missed something obvious. Can anyone shed some light on it? Edit: just for clarification, I am actually putting real values into the mysqli constructor :)
