  • Error using a hyphen as an object property name in Flex

    - by John Leonard
    I'm trying to assemble a header object for an api request. One of the headers is 'Content-Type'. The hyphen is causing a compile error. Flex is giving me: 1050 - Cannot assign to a non-reference value. I find it spiteful that they enjoy the use of a hyphen in the error message while I hang my head and come here for answers.

  • Kohanav3 ORM: calling where->find_all twice

    - by David Lawson
    When I do something like the following: $site = ORM::factory('site')->where('name', '=', 'Test Site')->find(); $users = $site->users; $deletedusers = $users->where('deleted', '=', '1')->find_all(); $nondeletedusers = $users->where('deleted', '=', '0')->find_all(); The contents of $deletedusers is correct, but the $nondeletedusers contains every non-deleted user, not just the ones in the loaded $site. What am I doing wrong?

  • conflicting declaration when filling a static std::map class member variable

    - by Max
    I have a class with a static std::map member variable that maps chars to a custom type Terrain. I'm attempting to fill this map in the class's implementation file, but I get several errors. Here's my header file: #ifndef LEVEL_HPP #define LEVEL_HPP #include <bitset> #include <list> #include <map> #include <string> #include <vector> #include "libtcod.hpp" namespace yarl { namespace level { class Terrain { // Member Variables private: std::bitset<5> flags; // Member Functions public: explicit Terrain(const std::string& flg) : flags(flg) {} (...) }; class Level { private: static std::map<char, Terrain> terrainTypes; (...) }; } } #endif and here's my implementation file: #include <bitset> #include <list> #include <map> #include <string> #include <vector> #include "Level.hpp" #include "libtcod.hpp" using namespace std; namespace yarl { namespace level { /* fill Level::terrainTypes */ map<char,Terrain> Level::terrainTypes['.'] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes[','] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes['\''] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes['`'] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes[178] = Terrain("11111"); // wall (...) } } I'm using g++, and the errors I get are src/Level.cpp:15: error: conflicting declaration ‘std::map, std::allocator yarl::level::Level::terrainTypes [46]’ src/Level.hpp:104: error: ‘yarl::level::Level::terrainTypes’ has a previous declaration as ‘std::map, std::allocator yarl::level::Level::terrainTypes’ src/Level.cpp:15: error: declaration of ‘std::map, std::allocator yarl::level::Level::terrainTypes’ outside of class is not definition src/Level.cpp:15: error: conversion from ‘yarl::level::Terrain’ to non-scalar type ‘std::map, std::allocator ’ requested src/Level.cpp:15: error: ‘yarl::level::Level::terrainTypes’ cannot be initialized by a non-constant expression when being declared I get a set of these for each map assignment line in the implementation file. Anyone see what I'm doing wrong? Thanks for your help.

  • MS Access MSChart.Graph.8 not printing

    - by Tanj
    Software: Microsoft Access 2007 SP2 Database File Version: Access 2000 I have an access program that I inherited from a previous employee. It uses forms for reports and since I don't have much experience in access I have continued to do this. I have created a copy of the program for another project and modified it to suit. I am having trouble getting more then one chart to print. All the charts display in form view, they all have the same properties (excepting data, position, etc.) For some reason they are not printing. They don't even show up in the print preview. I am thinking it must be something with the graphs themselves as they sometimes lose all information. I have to open the graphs in edit mode and change the data source from column to row and back again so that it gets redrawn. (Refresh doesn't fix it) So right now I don't even have a clue as to where to look so ideas are welcome. Edit #1 It seems to be a problem with linking to an unbound form. Subform Field Linker: Can't build a link between unbound forms. The query for the main form is SELECT tTest.ixTest, tMotorTypes.ixMotorType, tMotorTypes.asMotorType, tMotorTypes.fDeprecated, tTestType.asTest, tTest.asSerialNum, tTest.asOrderNum, tTest.asFrameNum, tTest.asRotorNum, tTest.asOperator, tTest.iStation, tTest.dtTestDate, tTest.ixTestType FROM tMotorTypes INNER JOIN (tTestType INNER JOIN tTest ON tTestType.ixTestType=tTest.ixTestType) ON tMotorTypes.ixMotorType=tTest.ixMotorType; The query for the chart is: SELECT qGraphRSTTemperatures.Frequency, qGraphRSTTemperatures.[Drive End], qGraphRSTTemperatures.[Non Drive End], qGraphRSTTemperatures.[Air In], qGraphRSTTemperatures.Core FROM qGraphRSTTemperatures ORDER BY qGraphRSTTemperatures.ixTemperature; Query qGraphRSTTemperatures: SELECT tElectricalData.dblFrequency AS Frequency, tTemperatures.dblDrvEnd AS [Drive End], tTemperatures.dblNonDrvEnd AS [Non Drive End], tTemperatures.dblAirIn AS [Air In], tTemperatures.dblCore AS Core, tSubTest.ixTest, tTemperatures.ixTemperature FROM (tSubTest INNER JOIN tElectricalData ON tSubTest.ixSubTest = tElectricalData.ixSubTest) LEFT JOIN tTemperatures ON tElectricalData.ixElectrical = tTemperatures.ixElectrical WHERE (((tSubTest.ixSubTestType)=5)) ORDER BY tSubTest.ixTest, tTemperatures.ixTemperature; So how come, in the form view it shows the graph with the correct data when linked thus: Child field: ixTest Master field: ixTest but won't print the graph. The graph will print if I remove the links, but then I have all the data from chart query as it is not limited by ixTest. edit #2 It seems to be a data retrieval/rendering issue in printing. Is there anything in printing that changes the context of records with respect to parent/child relationships?

  • Regex for Matching First Alphanumeric Character skipping (The |An? )

    - by TheLizardKing
    I have a list of artists, albums and tracks that I want to sort using the first letter of their respective name. The issue arrives when I want to ignore "The ", "A ", "An " and other various non-alphanumeric characters (Talking to you "Weird Al" Yankovic and [dialog]). Django has a nice start '^(An?|The) +' but I want to ignore those and a few others of my choice. I am doing this in Django, using a MySQL db with utf8_bin collation.

  • Is there any boost-independent version of boost/tr1 shared_ptr

    - by Artyom
    I'm looking for independent implementation of boost/tr1 shared_ptr, weak_ptr and enable_shared_from_this. I need: Boost independent very small implementation of these features. I need support of only modern compilers like GCC-4.x, MSVC-2008, Intel not things like MSVC6 or gcc-3.3 I need it to be licensed under non-copyleft LGPL compatible license like Boost/Mit/3-clause BSD. So I can include it in my library. Note - it is quite hard to extract shared_ptr from boost, at least BCP gives about 324 files...

  • Fastest primality test

    - by Grigory Javadyan
    Hi. Could you suggest a fast, deterministic method that is usable in practice, for testing if a large number is prime or not? Also, I would like to know how to use non-deterministic primality tests correctly. For example, if I'm using such a method, I can be sure that a number is not prime if the output is "no", but what about the other case, when the output is "probably"? Do I have to test for primality manually in this case? Thanks in advance.

  • Automatically capitalize first letter of first word in a new sentence in LaTeX

    - by Tom Hagen
    I know one of LaTeX's bragging points is that it doesn't have this Microsoftish behavior. Nevertheless, it's sometimes useful. LaTeX already adds an extra space after you type a (non-backslashed) period, so it should be possible to make it automatically capitalize the following letter as well. Is there an obvious way to write a macro that does this, or is there a LaTeX package that does it already?

  • XSLT - make xsl:analyze-string return string instead of sequence of strings?

    - by tohuwawohu
    Is it possible to make xsl:analyze-string return one string instead of a sequence of strings? Background: I'd like to use xsl:analyze-string in a xsl:function that should encapsulate the pattern matching. Ideally, the function should return an xs:string to be used as sort criteria in an xsl:sort element. At the moment, i have to apply string-join() on every result of the function call since xsl:analyze-string returns a sequence of strings, and xsl:sort doesn't accept such a sequence as sort criteria. See line 24 of the stylesheet: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:my="www.my-personal-namespa.ce" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xsl:output indent="yes" method="xml" /> <xsl:function name="my:sortierung" > <xsl:param name="inputstring" as="xs:string"/> <xsl:analyze-string select="$inputstring" regex="[0-9]+"> <xsl:matching-substring> <xsl:value-of select="format-number(number(.), '00000')" /> </xsl:matching-substring> <xsl:non-matching-substring> <xsl:value-of select="." /> </xsl:non-matching-substring> </xsl:analyze-string> </xsl:function> <xsl:template match="/input"> <result> <xsl:apply-templates select="value" > <xsl:sort select="string-join((my:sortierung(.)), ' ')" /> </xsl:apply-templates> </result> </xsl:template> <xsl:template match="value"> <xsl:copy-of select="." /> </xsl:template> </xsl:stylesheet> with this input: <?xml version="1.0" encoding="UTF-8"?> <input> <value>A 1 b 120</value> <value>A 1 b 1</value> <value>A 1 b 2</value> <value>A 1 b 1a</value> </input> In my example, is there a way to modify the xsl:function to return a xs:string instead of a sequence?

  • Could a truly random number be generated using pings to psuedo-randomly selected IP addresses?

    - by _ande_turner_
    The question posed came about during a 2nd Year Comp Science lecture while discussing the impossibility of generating numbers in a deterministic computational device. This was the only suggestion which didn't depend on non-commodity-class hardware. Subsequently nobody would put their reputation on the line to argue definitively for or against it. Anyone care to make a stand for or against. If so, how about a mention as to a possible implementation?

  • Is Prince the best way to PDF in Ruby on Rails?

    - by Angela
    After several Google searches, it appears that the way to create PDF's in Rails from HTML and CSS (versus a new markup language) is to use Prince. With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the what's and how's.

  • Building both devel and normal version of a RPM package

    - by ereOn
    Hi, I have a library from which I'd like to create two RPM packages. While I found several links on how to create a basic RPM package, I can't find how to create a devel package (see this question if you wonder what a devel package is). What do I have to do to generate both devel and non-devel versions of my RPM package ? Thanks.

  • Keeping track of business rules within IT department?

    - by evaldas-alexander
    I am looking for the best way to keep track of the business rules for both developers and everybody else (support staff / management) in a startup enviroment. The challenge is that our business model requires quite a lot of different business rules, which are created pretty much on the fly and evolving organically after that. After running this project for 3+ years, we have so many of such rules that often the only way to be sure about what the application is supposed to do in a certain situation is to go find the module responsible for that process and analyze its code and comments. That is all fine as long as you have one single developer who created the entire application from the scratch, but every new developer needs to go over pretty much entire codebase in order to understand how the application works. Even bigger problem is that non technical employees don't even have that option and therefore are forced to ask me pretty much every day how some certain case would be handled by the application. Quick example - we only start charging for our customer campaigns once they have been active for at least 72 hours, but at the same time we stop creating invoices for campaigns that belong to insolvent accounts and close such accounts within a month of the first failed charge. That does not apply to accounts that are set to "non-chargeable" which most commonly belongs to us since we are using the service ourselves. The invoices are created on the 1st of each month and include charges from the previous month + any current balance that the account might have. However, some customers are charged only 4 days after their invoice has been generated due to issues with their billing department. In addition to that, invoices are also created when customer deactivates his campaign, but that can only be done once the campaign is not longer under mandatory 6 month contract, unless account manager approves early deactivation. I know, that's quite a lot of rules that need to be taken into account when answering a question "when do we bill our customers", but actually I could still append an asterisk at the end of each sentence in order to disclose some rare exceptions. Of course, it would be easiest just to keep the business rules to the minimum, but we need to adapt to changing marketplace - i.e. less than a year ago we had no contracts whatsoever. One idea that I had so far was a simplistic wiki with categories corresponding to areas such as "Account activation", "Invoicing", "Collection procedures" and so on. Another idea would be to have giant interactive flowchart showing the entire customer "life cycle" from prospecting to account deactivation. What are your experiences / suggestions?

I have tried some different position arguments when popping up the dialog but non seems to help. Any clues? Is this a bug in the position calculation in JQuery? Or is this some css bug? Versions are 1.4.2 and 1.8.0

  • Must I Install a Gem to Unpack It?

    - by yar
    I wrote up some instructions for freezing a non-native gem in a Rails app today: install the gem sudo gem install fastercsv put the reference in the environment.rb (I think this is only necessary to do unpack with no GEM specified) config.gem "fastercsv" unpack the gem rake gems:unpack GEM=fastercsv uninstall the gem sudo gem uninstall fastercsv I know this must be the long way around: how can I unpack the gem without installing it first? Also: What's the difference between rake gems:unpack GEM=fastercsv and gem unpack fastercsv?
