  • Rails fixtures seem to be adding extra unexpected data

    - by Mason Jones
    Hello, all. I've got a dynamic fixture CSV file that's generating predictable data for a table in order for my unit tests to do their thing. It's working as expected and filling the table with the data, but when I check the table after the tests run, I'm seeing a number of additional rows of "blank" data (all zeros, etc). Those aren't being created by the fixture, and the unit tests are read-only, just doing selects, so I can't blame the code. There doesn't seem to be any logging done during the fixtures setup, so I can't see when the "blank" data is being inserted. Anyone ever run across this before, or have any ideas of how to log or otherwise see what the fixture setup is doing in order to trace down the source of the blank data?

  • assignment not working in a dll exported C++ class

    - by Jim Jones
    Using VS 2008 Have a C++ class in which I'm calling functions from a 3rd party dll. The definition in the header file is as follows: namespace OITImageExport { class ImageExport { private: SCCERR seResult; /* Error code returned. */ VTHDOC hDoc; /* Input doc handle returned by DAOpenDocument(). */ VTHEXPORT hExport; /* Handle to the export returned by EXOpenExport(). */ VTDWORD dwFIFlags; /* Used in setting the SCCOPT_FIFLAGS option. */ VTCHAR szError[256]; /* Error string buffer. */ VTDWORD dwOutputId; /* Output Format. */ VTDWORD dwSpecType; public: ImageExport(const char* outputId, const char* specType); void ProcessDocument(const char* inputPath, const char* outputPath); ~ImageExport(); }; } In the constructor I initialize two of the class fields having values which come from enumerations in the 3rd party dll: ImageExport::ImageExport(const char* outputId, const char* specType) { if(outputId == "jpeg") { dwOutputId = FI_JPEGFIF; } if(specType == "ansi") { dwSpecType = IOTYPE_ANSIPATH; } seResult = DAInit(); if (seResult != SCCERR_OK) { DAGetErrorString(seResult, szError, sizeof(szError)); fprintf(stderr, "DAInit() failed: %s (0x%04X)\n", szError, seResult); exit(seResult); } } When I use this class inside of a console app, with a main method in another file (all in the same namespace), instantiating the class object and calling the methods, it works like a champ. So, now that I know the basic code works, I open a dll project using the class header and code file. Course I have to add the dll macro, namely: #ifdef IMAGEDLL_EXPORTS #define DLL __declspec(dllexport) #else #define DLL __declspec(dllimport) #endif and changed the class definition to "class DLL ImageExport". Compiled nicely to a dll and .lib file (No errors, No warnings). Now to test this dll I open another console project using the same main method as before and linking to the (dll) lib file. Had problems, which when tracked down were the result of the two fields not being set; both had values of 0. Went back to the first console app and printed out the values: dwOutputId was 1535 (#define FI_JPEGFIF 1535) and dwSpecType was 2 (#define IOTYPE_ANSIPATH 2). Now if I was assigning these values outside of the class, I can see how the visibility could be different, but why is the assignment in the dll not working? Is it something about having a class in the dll?

  • How can I filter a report with duplicate fields in related records?

    - by Graham Jones
    I have a report where I need to filter out records where there is a duplicate contract number within the same station but a different date. It is not considered a duplicate value becuase of the different date. I then need to summarize the costs and count the contracts but even if i suppress the "duplicate fields" it will summarize the value. I want to select the record with the most current date. Station Trans-DT Cost Contract-No 8 5/11/2010 10 5008 8 5/12/2010 15 5008 9 5/11/2010 12 5012 9 5/15/2010 50 5012

  • Flex custom toggleswitch not working in actionscript

    - by Gavin Jones
    I have a custom Flex Toggleswitch component that changes the text values of the switch. package skins { import spark.skins.mobile.ToggleSwitchSkin; public class MyToggleSwitchSkin extends ToggleSwitchSkin { public function MyToggleSwitchSkin() { super(); selectedLabel="Serviceable"; unselectedLabel="Fault"; } } } If I add the control using the MXML tag, it works fine. However, when I add the component using action script, it does not. import skins.MyToggleSwitchSkin; public function addToggle():void { var myCustomToggle:MyToggleSwitchSkin = new MyToggleSwitchSkin(); hgroup.addElement(myCustomToggle); } The control dsiplays but will not activate. Any ideas what I have missed?

  • Another void C# question

    - by Jim Jones
    Have a type in the header files I'm working with called VTVOID it is the type of a struct element and a number of parameters. In the header file defining types is the line #define VTVOID void I read in another discussion the void maps to System.Void however when I plug that into the C# code I get the error "System.Void cannot be used in C# -- use typeof(void) to get the void object." So what type do I plug in? Jim

  • g++ doesn't think I'm passing a reference

    - by Ben Jones
    When I call a method that takes a reference, g++ complains that I'm not passing a reference. I thought that the caller didn't have to do anything different for PBR. Here's the offending code: //method definition void addVertexInfo(VertexInfo &vi){vertexInstances.push_back(vi);} //method call: sharedVertices[index]->addVertexInfo(VertexInfo(n1index, n2index)); And here's the error: GLUtils/GLMesh.cpp: In member function 'void GLMesh::addPoly(GLIndexedPoly&)': GLUtils/GLMesh.cpp:110: error: no matching function for call to 'SharedVertexInfo::addVertexInfo(VertexInfo)' GLUtils/GLMesh.h:93: note: candidates are: void SharedVertexInfo::addVertexInfo(VertexInfo&)

  • Applied style in WPF ignores properties.

    - by Quenton Jones
    Here's the conundrum. In two different places in my application, I use a border with the exact same appearance. In an never-ending fight against code bloat and unmanageable code, I want to define the border's appearance in a style to use when I create the border. Strangely, several of the properties I set are being ignored. Here's the code I use to create the style. Simple enough. Style borderStyle = new Style(typeof(Border)); borderStyle.Setters.Add(new Setter(Border.BorderBrushProperty, Brushes.Black)); borderStyle.Setters.Add(new Setter(Border.BorderThicknessProperty, new Thickness(4))); borderStyle.Setters.Add(new Setter(Border.OpacityProperty, 1.0)); return borderStyle; But when I set the style, the opacity property is left at its original value of 0.7. I have also tried setting the background of the border to a brush I created. It too is ignored. Thanks for any insights you may have.

  • How to discover getters and setters on hibernate objects

    - by Michael Jones
    I need to find a way of taking a hibernate object and discovering at runtime all of the getter methods that relate to persistable fields. I'm using annotations in the classes but have previously had difficulties working with them (I ran into a 2 year old bug the java developers still haven't fixed). Does anyone know how I can do this please, ideally without using annotations? Thanks. PS - What I'm trying to do here is to update a new object with values from an existing object dynamically.

  • How to access a subset of XML data in Java when the XML data is too large to fit in memory?

    - by Michael Jones
    What I would really like is a streaming API that works sort of like StAX, and sort of like DOM/JDom. It would be streaming in the sense that it would be very lazy and not read things in until needed. It would also be streaming in the sense that it would read everything forwards (but not backwards). Here's what code that used such an API would look like. URL url = ... XMLStream xml = XXXFactory(url.inputStream()) ; // process each <book> element in this document. // the <book> element may have subnodes. // You get a DOM/JDOM like tree rooted at the next <book>. while (xml.hasContent()) { XMLElement book = xml.getNextElement("book"); processBook(book); } Does anything like this exist?

  • Storing PDFs in MS Access Database using Forms

    - by Matthew Jones
    I need to store PDF files in an Access database on a shared drive using a form. I figured out how to do this in tables (using the OLE Object field, then just drag-and-drop) but I would like to do this on a Form that has a Save button. Clicking the save button would store the file (not just a link) in the database. Any ideas on how to do this? EDIT: I am using Access 2003, and the DB will be stored on a share drive, so I'm not sure linking to the files will solve the problem.

  • Pick an image from the Gallery

    - by Steve Jones
    I have seen a lot of posts about this, and it seems like the code below should work. I have created an SD Card image and added it to the emulator (and that works fine). Intent intent = new Intent(Intent.ACTION_PICK); intent.setType("image/*"); //intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(intent, 1); It does launch and allow selection of images, but when I click on an image, everything exits and the emulator returns to the home screen, not the back to my app. My onActivityResult is never called either. What am I missing?

  • AllowSetForegroundWindow & SetForegroundWindow: NPAPI plug-in wants to allow a desktop application with no success

    - by David Robert Jones
    Here it's what I have: a web browser plug-in written in C++ and a Windows application written in C#. They communicate through a named pipe. The plug-in instructs the C# application to open a file (suppose that the file is a .txt and it opens in Notepad). Once the C# application is given the command, it opens the file but Notepad doesn't show in the foreground, which isn't acceptable, I must open Notepad in the foreground. I modified the C# application so that it calls the SetForegroundWindow function. This time Notepad didn't open in the foreground, but the taskbar flashes. After reading the documentation for SetForegroundWindow and many articles I think that now I understand what the problem is: the C# application can't bring Notepad to the foreground because it wasn't the the foreground process, the browser was (?). After reading this: "A process that can set the foreground window can enable another process to set the foreground window by calling the AllowSetForegroundWindow function." I decided to modify the plug-in. This time the plug-in calls the AllowSetForegroundWindow function passing ASFW_ANY as a parameter (I know, ASFW_ANY could be risky, but I wanted to make sure that AllowSetForegroundWindow would do it). After I did the modification to the plug-in I tested it and it worked! (Opera 12.02). Then I tested it on Internet Explorer and it worked too. But the problem came when I tested it in Firefox and Chrome. The C# application didn't have the ability to bring Notepad to the foreground. I noticed that for those browsers the AllowSetForegroundWindow function was returning false. So I started investigating and I come to the conclusion that maybe it's because the plugin container that Firefox uses. An idea came to my mind: it worked in Opera 12.02, but they don't have a plugin container, although they did in Opera 12.00. So I downloaded Opera 12.00, I did the test and it failed, which makes me conclude that the plugin container is the culprit. The question is: how can I give to the C# application the ability to set foreground? I don't know how to continue, and I think that I tried all the legitimate ways. The AllowSetForegroundWindow & SetForegroundWindow seems to not apply here.

  • Why is the operation address incremented by two?

    - by Gavin Jones
    I am looking at a Javascript emulator of a NES to try and understand how it works. On this line: addr = this.load(opaddr+2); The opcode is incremented by two. However, the documentation (see appendix E) I'm reading says: Zero page addressing uses a single operand which serves as a pointer to an address in zero page ($0000-$00FF) where the data to be operated on can be found. By using zero page addressing, only one byte is needed for the operand, so the instruction is shorter and, therefore, faster to execute than with addressing modes which take two operands. An example of a zero page instruction is AND $12. So if the operand's argument is only one byte, shouldn't it appear directly after it, and be + 1 instead of + 2? Why +2? This is how I think it works, which may be incorrect. Suppose our memory looks like: ------------------------- | 0 | 1 | 2 | 3 | 4 | 5 | <- index ------------------------- | a | b | c | d | e | f | <- memory ------------------------- ^ \ PC and our PC is 0, pointing to a. For this cycle, we say that the opcode: var pc= 0; //for example's sake var opcode= memory[pc]; //a So shouldn't the first operand be the next slot, i.e. b? var first_operand = memory[pc + 1]; //b
