  • Intercepting Xstream conversion while parsing XML

    - by Shane Bell
    Suppose I have a simple Java class like this: public class User { String firstName; String lastName; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } } Now, suppose I want to parse the following XML: <user> <firstName>Homer</firstName> <lastName>Simpson</lastName> </user> I can do this with no problems in XStream like so: User homer = (User) xstream.fromXML(xml); Ok, all good so far, but here's my problem. Suppose I have the following XML that I want to parse: <user> <fullName>Homer Simpson</fullName> </user> How can I convert this XML into the same User object using XStream? I'd like a way to implement some kind of callback so that when XStream parses the fullName field, I can split the string in two and manually set the first name and last name fields on the user object. Is this possible? Note that I'm not asking how to split the string in two (that's the easy part), I want to know how to intercept the XML parsing so XStream doesn't try to reflectively set the fullName field on the User object (which obviously doesn't exist). I looked at the converters that XStream provides but couldn't figure out how to use it for this purpose. Any help would be appreciated.

  • How to get webcam video stream bytes in c++

    - by Mr Bell
    I am targeting windows machines. I need to get access to the pointer to the byte array describing the individual streaming frames from an attached usb webcam. I saw the playcap directshow sample from the windows sdk, but I dont see how to get to raw data, frankly, I don't understand how the video actually gets to the window. Since I don't really need anything other than the video capture I would prefer not to use opencv. Visual Studio 2008 c++

  • Game engine deployment strategy for the Android?

    - by Jeremy Bell
    In college, my senior project was to create a simple 2D game engine complete with a scripting language which compiled to bytecode, which was interpreted. For fun, I'd like to port the engine to android. I'm new to android development, so I'm not sure which way to go as far as deploying the engine on the phone. The easiest way I suppose would be to require the engine/interpreter to be bundled with every game that uses it. This solves any versioning issues. There are two problems with this. One: this makes each game app larger and two: I originally released the engine under the LGPL license (unfortunately), but this deployment strategy makes it difficult to conform to the rules of that license, particularly with respect to allowing users to replace the lib easily with another version. So, my other option is to somehow have the engine stand alone as an Activity or service that somehow responds to intents raised by game apps, and somehow give the engine app permissions to read the scripts and other assets to "run" the game. The user could then be able to replace the engine app with a different version (possibly one they made themselves). Is this even possible? What would you recommend? How could I handle it in a secure way?

  • How do i render a web cam filter instead of video file in directshow?

    - by Mr Bell
    How do i render a web cam filter instead of video file? I am looking at the vmr9compositor example included in the directshow sdk. It renders a video file. I would like to stream in the feed from the webcam. It SEEMS like this should be possible, but I dont have much of a grasp on directshow. It uses this method call currently: hr = g_graph->RenderFile( pFileName, NULL ); Looking at the playcap example in the sdk which can display the web cam feed in a window, I see that it uses hr = g_pCapture->RenderStream (&PIN_CATEGORY_PREVIEW, &MEDIATYPE_Video, pSrcFilter, NULL, NULL)); to display the web cam stream. pSrcFilter is an IBaseFilter. How can I can swap the video file in the vmr app with the web cam feed? Windows XP, Visual Studio 2008 C++

  • c++ callback syntax in a class

    - by Mr Bell
    I am trying to figure out the syntax to register a callback with this 3rd party software. I think it is probably a basic question, I just am not too familiar with c++. They have a method for registering a callback function so their code can call a function in my code when an event happens. They provided a working example that registers the callback from the main file, but I want to know how to do it when working inside a class Their method signature: smHTRegisterHeadPoseCallback(smEngineHandle engine_handle, void *user_data, smHTHeadPoseCallback callback_fun); Working example from the main file: void STDCALL receiveHeadPose(void *,smEngineHeadPoseData head_pose, smCameraVideoFrame video_frame) { ... } void main() { ... smHTRegisterHeadPoseCallback(engine_handle,0,receiveHeadPose) ... } But I want to use this from my class MyClass.h class FaceEngine { public: void STDCALL receiveFaceData(void *, smEngineFaceData face_data, smCameraVideoFrame video_frame); ... MyClass.cpp void FaceEngine::Start(void) { rc = smHTRegisterFaceDataCallback(hFaceAPIEngine,0,&FaceEngine::receiveFaceData); ... Results in this compiler error: Error 1 error C2664: 'smHTRegisterFaceDataCallback' : cannot convert parameter 3 from 'void (__stdcall FaceEngine::* )(void *,smEngineFaceData,smCameraVideoFrame)' to 'smHTFaceDataCallback' d:\stuff\programming\visual studio 2008\projects\tut02_vertices\faceengine.cpp 43 Beard If my question isn't clear please let me know how I can clarify.

  • Ridiculously Simple Erlang Question

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and is there any guarantee of order when processing messages? ie. Received in order sent? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

  • Time order of messages

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie.

  • How to debug c++ DirectShow filter

    - by Mr Bell
    What debugging tools are available for directshow filters? Presently, I have a project that compiles and registers a video source filter that I then setup a graph in GraphEdit. I am using c++ in visual studio 2008. Is it possible to get a debugger attached to the filter in any way where I could set break points, inspect variables, etc? Barring that is there a way to log diagnostic information somewhere that I can view in real time?

  • Can PHP Perform Magic Instantiation?

    - by Aiden Bell
    Despite PHP being a pretty poor language and ad-hoc set of libraries ... of which the mix of functions and objects, random argument orders and generally ill-thought out semantics mean constant WTF moments.... ... I will admit, it is quite fun to program in and is fairly ubiquitous. (waiting for Server-side JavaScript to flesh out though) question: Given a class class RandomName extends CommonAppBase {} is there any way to automatically create an instance of any class extending CommonAppBase without explicitly using new? As a rule there will only be one class definition per PHP file. And appending new RandomName() to the end of all files is something I would like to eliminate. The extending class has no constructor; only CommonAppBase's constructor is called. Strange question, but would be nice if anyone knows a solution. Thanks in advance, Aiden (btw, my PHP version is 5.3.2) Please state version restrictions with any answer.

  • Convert integer to formatted LPCWSTR. C++

    - by Mr Bell
    I have a direct3d project that uses D3DXCreateTextureFromFile() to load some images. This function takes a LPCWSTR for the path to file. I want to load a series of textures that are numbered consecutively (ie. MyImage0001.jpg, MyImage0002.jpg, etc) But c++'s crazy strings confuse me. How do i: for(int i=0; i < 3;i++) { //How do I convert i into a string path i can use with D3DXCreateTextureFromFile? }

  • Detect a USB drive being inserted - Windows Service

    - by Tom Bell
    I am trying to detect a USB disk drive being inserted within a Windows Service, I have done this as a normal Windows application. The problem is the following code doesn't work for volumes. Registering the device notification: DEV_BROADCAST_DEVICEINTERFACE notificationFilter; HDEVNOTIFY hDeviceNotify = NULL; ::ZeroMemory(&notificationFilter, sizeof(notificationFilter)); notificationFilter.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE); notificationFilter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE; notificationFilter.dbcc_classguid = ::GUID_DEVINTERFACE_VOLUME; hDeviceNotify = ::RegisterDeviceNotification(g_serviceStatusHandle, &notificationFilter, DEVICE_NOTIFY_SERVICE_HANDLE); The code from the ServiceControlHandlerEx function: case SERVICE_CONTROL_DEVICEEVENT: PDEV_BROADCAST_HDR pBroadcastHdr = (PDEV_BROADCAST_HDR)lpEventData; switch (dwEventType) { case DBT_DEVICEARRIVAL: ::MessageBox(NULL, "A Device has been plugged in.", "Pounce", MB_OK | MB_ICONINFORMATION); switch (pBroadcastHdr->dbch_devicetype) { case DBT_DEVTYP_DEVICEINTERFACE: PDEV_BROADCAST_DEVICEINTERFACE pDevInt = (PDEV_BROADCAST_DEVICEINTERFACE)pBroadcastHdr; if (::IsEqualGUID(pDevInt->dbcc_classguid, GUID_DEVINTERFACE_VOLUME)) { PDEV_BROADCAST_VOLUME pVol = (PDEV_BROADCAST_VOLUME)pDevInt; char szMsg[80]; char cDriveLetter = ::GetDriveLetter(pVol->dbcv_unitmask); ::wsprintfA(szMsg, "USB disk drive with the drive letter '%c:' has been inserted.", cDriveLetter); ::MessageBoxA(NULL, szMsg, "Pounce", MB_OK | MB_ICONINFORMATION); } } return NO_ERROR; } In a Windows application I am able to get the DBT_DEVTYP_VOLUME in dbch_devicetype, however this isn't present in a Windows Service implementation. Has anyone seen or heard of a solution to this problem, without the obvious, rewrite as a Windows application?

  • C++ snippet support in visual studio?

    - by Jeremy Bell
    I'm writing code in native C++ (not C++/CLR). I know that there is no built-in support for C++ with regards to the snippet manager and snipper picker interfaces, however I found a utility called "snippy" which supposedly can generate C++ snippets. Here is a c++ snippet that the program generated: <?xml version="1.0" encoding="utf-8"?> <CodeSnippets xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet"> <CodeSnippet Format="1.0.0"> <Header> <Title>MySnippet</Title> <Shortcut>MySnippet</Shortcut> <Description>Just a test snippet</Description> <Author>Me</Author> <SnippetTypes> <SnippetType>Expansion</SnippetType> </SnippetTypes> </Header> <Snippet> <Declarations> <Literal Editable="true"> <ID>literal1</ID> <ToolTip>just a placeholder</ToolTip> <Default> </Default> <Function> </Function> </Literal> </Declarations> <Code Language="cpp"><![CDATA[cout << "$literal1$" << std::endl;]]></Code> </Snippet> </CodeSnippet> </CodeSnippets> If there is support in visual C++, even in a limited capacity, for C++ snippets, how do I add them to my environment, and what are the limitations? All I need is support for basic expansion snippets that I can invoke by typing a shortcut and hitting tab, and which supports basic literals that I can tab through (basically, if it supports the above snippet, I'm good). If this can't be done, are there any free add-ons or extensions to visual studio that support snippets for C++? I'm using both visual studio 2010 and 2008, but I mostly write code in 2010 right now.

  • NUnit, CollectionAssert.AreEquivalent(...,...), C# Question

    I new to NUnit and looking for an explination as to why this test fails? I get the following exception when running the test. NUnit.Framework.AssertionException: Expected: equivalent to < <....ExampleClass, <....ExampleClass But was: < <....ExampleClass, <....ExampleClass using NUnit.Framework; using System.Collections.ObjectModel; public class ExampleClass { public ExampleClass() { Price = 0m; } public string Description { get; set; } public string SKU { get; set; } public decimal Price { get; set; } public int Qty { get; set; } } [TestFixture] public class ExampleClassTests { [Test] public void ExampleTest() { var collection1 = new Collection<ExampleClass> { new ExampleClass {Qty = 1, SKU = "971114FT031M"}, new ExampleClass {Qty = 1, SKU = "971114FT249LV"} }; var collection2 = new Collection<ExampleClass> { new ExampleClass {Qty = 1, SKU = "971114FT031M"}, new ExampleClass {Qty = 1, SKU = "971114FT249LV"} }; CollectionAssert.AreEquivalent(collection1, collection2); } }

  • Subversion: Change working directory's target repo

    - by Aiden Bell
    I know, other RCS are better, but... I have moved an SVN repository from file:///path/to/repo to http://host.name/svn/repo but there is a working directory (checkout out from file://) with changes that want commiting to the http location. How then, can I change the repo a working directory will commit to when issuing svn commit? I'd rather do that than checkout a new copy and sync changes locally. Also, handy to know for the future.
