  • Dependecy Injection with Massive ORM: dynamic trouble

    - by Sergi Papaseit
    I've started working on an MVC 3 project that needs data from an enormous existing database. My first idea was to go ahead and use EF 4.1 and create a bunch of POCO's to represent the tables I need, but I'm starting to think the mapping will get overly complicated as I only need some of the columns in some of the tables. (thanks to Steven for the clarification in the comments. So I thought I'd give Massive ORM a try. I normally use a Unit of Work implementation so I can keep everything nicely decoupled and can use Dependency Injection. This is part of what I have for Massive: public interface ISession { DynamicModel CreateTable<T>() where T : DynamicModel, new(); dynamic Single<T>(string where, params object[] args) where T : DynamicModel, new(); dynamic Single<T>(object key, string columns = "*") where T : DynamicModel, new(); // Some more methods supported by Massive here } And here's my implementation of the above interface: public class MassiveSession : ISession { public DynamicModel CreateTable<T>() where T : DynamicModel, new() { return new T(); } public dynamic Single<T>(string where, params object[] args) where T: DynamicModel, new() { var table = CreateTable<T>(); return table.Single(where, args); } public dynamic Single<T>(object key, string columns = "*") where T: DynamicModel, new() { var table = CreateTable<T>(); return table.Single(key, columns); } } The problem comes with the First(), Last() and FindBy() methods. Massive is based around a dynamic object called DynamicModel and doesn't define any of the above method; it handles them through a TryInvokeMethod() implementation overriden from DynamicObject instead: public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, out object result) { } I'm at a loss on how to "interface" those methods in my ISession. How could my ISession provide support for First(), Last() and FindBy()? Put it another way, how can I use all of Massive's capabilities and still be able to decouple my classes from data access?

  • Problems with ASP.NET, machine-level web.config, and the location element

    - by Daniel Schaffer
    I've got a server running Windows Web Server 2008 R2. The machine-level web.config has the following entries: <location path="Preview"> <appSettings> <add key="Environment" value="Preview" /> </appSettings> </location> <location path="Staging"> <appSettings> <add key="Environment" value="Staging" /> </appSettings> </location> <location path="Production"> <appSettings> <add key="Environment" value="Production" /> </appSettings> </location> I have a website that I'd set up in the direction D:\Sites\Preview\, so the full path would be D:\Sites\Preview\WebSite1. If I put a simple aspx file that just outputs the value of ConfigurationManager.AppSettings["Environment"], it displays the value Preview. I'm not clear on exactly how that works, but it does. I'd set this up several weeks ago, and just now tried to duplicate this - I put a second site in the D:\Sites\Preview\ directory, expecting that it would automatically pick up the appropriate appSettings entries, but for some reason it hasn't - the same aspx page doesn't show anything. Additionally, when I go into the IIS manager and open the Configuration Editor, there are no settings in there, whereas there are settings listed for the first site. Any ideas as to what I could be missing? Is the location element intended to work like this, or did I just find some magical fluke with my first site?

  • Turning a JSON list into a POJO

    - by Josh L
    I'm having trouble getting this bit of JSON into a POJO. I'm using Jackson configured like this: protected ThreadLocal<ObjectMapper> jparser = new ThreadLocal<ObjectMapper>(); public void receive(Object object) { try { if (object instanceof String && ((String)object).length() != 0) { ObjectDefinition t = null ; if (parserChoice==0) { if (jparser.get()==null) { jparser.set(new ObjectMapper()); } t = jparser.get().readValue((String)object, ObjectDefinition.class); } Object key = t.getKey(); if (key == null) return; transaction.put(key,t); } } catch (Exception e) { e.printStackTrace(); } } Here's the JSON that needs to be turned into a POJO: { "id":"exampleID1", "entities":{ "tags":[ { "text":"textexample1", "indices":[ 2, 14 ] }, { "text":"textexample2", "indices":[ 31, 36 ] }, { "text":"textexample3", "indices":[ 37, 43 ] } ] } And lastly, here's what I currently have for the java class: protected Entities entities; @JsonIgnoreProperties(ignoreUnknown = true) protected class Entities { public Entities() {} protected Tags tags; @JsonIgnoreProperties(ignoreUnknown = true) protected class Tags { public Tags() {} protected String text; public String getText() { return text; } public void setText(String text) { this.text = text; } }; public Tags getTags() { return tags; } public void setTags(Tags tags) { this.tags = tags; } }; //Getters & Setters ... I've been able to translate the more simple objects into a POJO, but the list has me stumped. Any help is appreciated. Thanks!

  • A monkey could do this better - Access to and availability of private member functions in C++

    - by David
    I am wandering the desert of my brain. I'm trying to write something like the following: class MyClass { // Peripherally Related Stuff public: void TakeAnAction(int oneThing, int anotherThing) { switch(oneThing){ case THING_A: TakeThisActionWith(anotherThing); break; //cases THINGS_NOT_A: }; private: void TakeThisActionWith(int thing) { string outcome = new string; outcome = LookUpOutcome(thing); // Do some stuff based on outcome return; } string LookUpOutcome(int key) { string oc = new string; oc = MyPrivateMap[key]; return oc; } map<int, string> MyPrivateMap; Then in the .cc file where I am actually using these things, while compiling the TakeAnAction section, it [CC, the solaris compiler] throws an an error: 'The function LookUpOutcome must have a prototype' and bombs out. In my header file, I have declared 'string LookUpOutcome(int key);' in the private section of the class. I have tried all sorts of variations. I tried to use 'this' for a little while, and it gave me 'Can only use this in non-static member function.' Sadly, I haven't declared anything static and these are all, putatively, member functions. I tried it [on TakeAnAction and LookUp] when I got the error, but I got something like, 'Can't access MyPrivateMap from LookUp'. MyPrivateMap could be made public and I could refer to it directly, I guess, but my sensibility says that is not the right way to go about this [that means that namespace scoped helper functions are out, I think]. I also guess I could just inline the lookup and subsequent other stuff, but my line-o-meter goes on tilt. I'm trying desperately not to kludge it.

  • .NET Assembly Diff / Compare Tool - What's available?

    - by STW
    I'd like to be able to do a code-level diff between two assemblies; the Diff plug-in for Reflector is the closest thing I've found so far, but to compare the entire assembly is a manual process requiring me to drill-down into every namespace/class/method. The other tools I've found so far appear to be limited to API-level (namespaces, classes, methods) differences--which won't cut it for what I'm looking for. Does anyone know of such a tool? My requirements (from highest to lowest) are: Be able to analyze / reflect the code content of two versions of the same assembly and report the differences Accept a folder or group of assemblies as input; quickly compare them (similar to WinMerge's folder diff's) Quick ability to determine if two assemblies are equivalent at the code level (not just the API's) Allow easy drill-down to view the differences Exporting of reports regarding the differences (Personally I like WinMerge for text diffs, so an application with a similar interface would be great)

  • Using NSXMLParser to parse Vimeo XML on iPhone.

    - by Sonny Fazio
    Hello, I'm working on an iPhone app that will use Vimeo Simple API to give me a listing our videos by a certain user, in a convenient TableView format. I'm new to Parsing XML and have tried TouchXML, TinyXML, and now NSXMLParser with no luck. Most tutorials on parsing XML are for a blog, and not for an API XML sheet. I've tried modifying the blog parsers to search for the specific tags, but it doesn't seem to work. Right now I'm working with NSXMLParser and it seems to correctly find the value of an XML tag, but when it goes to append it to a NSMutableString, it writes a whole bunch of nulls in between it. I'm using a tutorial from theappleblog and modifying it to work with Vimeo API - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ if ([currentElement isEqualToString:@"video_title"]) { NSLog(@"String: %@",string); [currentTitle appendString:string]; } else if ([currentElement isEqualToString:@"video_url"]) { [currentLink appendString:string]; } else if ([currentElement isEqualToString:@"video_description"]) { [currentSummary appendString:string]; } else if ([currentElement isEqualToString:@"date"]) { [currentDate appendString:string]; } Here is the nulls it writes: http://grab.by/grabs/92d9cfc2df4fac3fe6579493b1a8e89f.png Then when it finishes, it has to add the NSMutableStrings into a NSMutableDictionary - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ //NSLog(@"found this element: %@", elementName); currentElement = [elementName copy]; if ([elementName isEqualToString:@"item"]) { // clear out our story item caches... item = [[NSMutableDictionary alloc] init]; currentTitle = [[NSMutableString alloc] init]; currentDate = [[NSMutableString alloc] init]; currentSummary = [[NSMutableString alloc] init]; currentLink = [[NSMutableString alloc] init]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ NSLog(@"Title: %@",currentTitle); if ([elementName isEqualToString:@"item"]) {// save values to an item, then store that item into the array... [item setObject:currentTitle forKey:@"video_title"]; NSLog(@"Current Title%@", currentTitle); [item setObject:currentLink forKey:@"video_url"]; [item setObject:currentSummary forKey:@"video_description"]; [item setObject:currentDate forKey:@"date"]; [stories addObject:[item copy]]; NSLog(@"adding story: %@", currentTitle); } } I would really appreciate it if someone has any advance

  • OpenAL - determine maximum sources

    - by Bill Kotsias
    Is there an API that allows you to define the maximum number of OpenAL "sources" allowed by the underlying sound hardware? Searching the internet, I found 2 recommendations : keep generating OpenAL sources till you get an error. However, there is a note in FreeSL (OpenAL wrapper) stating that this is "very bad and may even crash the library" assume you only have 16; why would anyone ever require more? (!) The second recommendation is even adopted by FreeSL. So, is there a common API to define the number of simultaneous "voices" supported? Thank you for your time, Bill

  • How difficult is it to migrate away from Google App Engine?

    - by Ignas Limanauskas
    I am thinking of making an (initially) small Web Application, which would eventually have a potential to grow. All things considered Google App Engine seems like a very attractive option. Say, user base and complexity grows and for one or other reason I needed to leave GAE behind. How difficult would it be to migrate away? 1) Does GAE provide a way to export the database? What format would it be? Would it be difficult to put it under MySQL (or similar)? 2) In which areas (ex. database access, others?) would I have to use GAE API? I.e. which parts of implementation would have to be abstracted away / interfaced? 3) Alternatively, is it even worth to keep GAE API outside, say, if there is nothing much I would need to use.

  • Is this an idiomatic way to pass mocks into objects?

    - by Billy ONeal
    I'm a bit confused about passing in this mock class into an implementation class. It feels wrong to have all this explicitly managed memory flying around. I'd just pass the class by value but that runs into the slicing problem. Am I missing something here? Implementation: namespace detail { struct FileApi { virtual HANDLE CreateFileW( __in LPCWSTR lpFileName, __in DWORD dwDesiredAccess, __in DWORD dwShareMode, __in_opt LPSECURITY_ATTRIBUTES lpSecurityAttributes, __in DWORD dwCreationDisposition, __in DWORD dwFlagsAndAttributes, __in_opt HANDLE hTemplateFile ) { return ::CreateFileW(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile); } virtual void CloseHandle(HANDLE handleToClose) { ::CloseHandle(handleToClose); } }; } class File : boost::noncopyable { HANDLE hWin32; boost::scoped_ptr<detail::FileApi> fileApi; public: File( __in LPCWSTR lpFileName, __in DWORD dwDesiredAccess, __in DWORD dwShareMode, __in_opt LPSECURITY_ATTRIBUTES lpSecurityAttributes, __in DWORD dwCreationDisposition, __in DWORD dwFlagsAndAttributes, __in_opt HANDLE hTemplateFile, __in detail::FileApi * method = new detail::FileApi() ) { fileApi.reset(method); hWin32 = fileApi->CreateFileW(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile); } }; namespace detail { struct FileApi { virtual HANDLE CreateFileW( __in LPCWSTR lpFileName, __in DWORD dwDesiredAccess, __in DWORD dwShareMode, __in_opt LPSECURITY_ATTRIBUTES lpSecurityAttributes, __in DWORD dwCreationDisposition, __in DWORD dwFlagsAndAttributes, __in_opt HANDLE hTemplateFile ) { return ::CreateFileW(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile); } virtual void CloseHandle(HANDLE handleToClose) { ::CloseHandle(handleToClose); } }; } class File : boost::noncopyable { HANDLE hWin32; boost::scoped_ptr<detail::FileApi> fileApi; public: File( __in LPCWSTR lpFileName, __in DWORD dwDesiredAccess, __in DWORD dwShareMode, __in_opt LPSECURITY_ATTRIBUTES lpSecurityAttributes, __in DWORD dwCreationDisposition, __in DWORD dwFlagsAndAttributes, __in_opt HANDLE hTemplateFile, __in detail::FileApi * method = new detail::FileApi() ) { fileApi.reset(method); hWin32 = fileApi->CreateFileW(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile); } ~File() { fileApi->CloseHandle(hWin32); } }; Tests: namespace detail { struct MockFileApi : public FileApi { MOCK_METHOD7(CreateFileW, HANDLE(LPCWSTR, DWORD, DWORD, LPSECURITY_ATTRIBUTES, DWORD, DWORD, HANDLE)); MOCK_METHOD1(CloseHandle, void(HANDLE)); }; } using namespace detail; using namespace testing; TEST(Test_File, OpenPassesArguments) { MockFileApi * api = new MockFileApi; EXPECT_CALL(*api, CreateFileW(Eq(L"BozoFile"), Eq(56), Eq(72), Eq(reinterpret_cast<LPSECURITY_ATTRIBUTES>(67)), Eq(98), Eq(102), Eq(reinterpret_cast<HANDLE>(98)))) .Times(1).WillOnce(Return(reinterpret_cast<HANDLE>(42))); File test(L"BozoFile", 56, 72, reinterpret_cast<LPSECURITY_ATTRIBUTES>(67), 98, 102, reinterpret_cast<HANDLE>(98), api); }

  • Cancel page forward/back hotkeys in Firefox with Greasemonkey

    - by Stimulating Pixels
    First the background: In Firefox 3.6.3 on Mac OS X 10.5.8 when entering text into a standard the hotkey combination of Command+LeftArrow and Command+RightArrow jump the cursor to the start/end of the current line, respectively. However, when using CKEditor, FCKEditor and YUI Editor, Firefox does not seem to completely recognize that it's a text area. Instead, it drops back to the default function for those hotkeys which is to move back/forward in the browser history. After this occurs, the text in the editor is also cleared when you return to the page making it very easy to loose whatever is being worked on. I'm attempting to write a greasemonkey script that I can use to capture the events and prevent the page forward/back jumps from being executed. So far, I've been able to see the events with the following used as a .user.js script in GreaseMonkey: document.addEventListener('keypress', function (evt) { // grab the meta key var isCmd = evt.metaKey; // check to see if it is pressed if(isCmd) { // if so, grab the key code; var kCode = evt.keyCode; if(kCode == 37 || kCode == 39) { alert(kCode); } } }, false ); When installed/enabled, pressing command+left|right arrow key pops an alert with the respective code, but as soon as the dialog box is closed, the browser executes the page forward/back move. I tried setting a new code with evt.keyCode = 0, but that didn't work. So, the question is, can this Greasemonkey script be updated so that it prevents the back/forward page moves? (NOTE: I'm open to other solutions as well. Doesn't have to be Greasemonkey, that's just the direction I've tried. The real goal is to be able to disable the forward/back hotkey functionality.)

  • oracle hibernate + maven dependenciesm dbcp.basicdatasource exception

    - by Joe
    I'm trying to create a web application using maven, tomcat and hibernate. Now I'm getting a cannot find class for org.appache.commons.dbcp.basicdatasource for bean with name datasource... exception. Without the hibernate aspects it works fine, but if I add <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="mappingResources"> <list> </list> </property> </bean> to my applicationContext then I get the error. What I did was: -add org.hibernate to my pom -put ojdbc16.jar in my tomcat bin folder -add the above snippet to my applicationContext.xml I use a bat file to compile my project (using maven), copy it to my tomcat webapp folder and to start the server. Any input on what I'm doing wrong is welcome.

  • What would you recommend for a large-scale Java data grid technology: Terracotta, GigaSpaces, Cohere

    - by cliff.meyers
    I've been reading up on so-called "data grid" solutions for the Java platform including Terracotta, GigaSpaces and Coherence. I was wondering if anyone has real-world experience working any of these tools and could share their experience. I'm also really curious to know what scale of deployment people have worked with: are we talking 2-4 node clusters or have you worked with anything significantly larger than that? I'm attracted to Terracotta because of its "drop in" support for Hibernate and Spring, both of which we use heavily. I also like the idea of how it decorates bytecode based on configuration and doesn't require you to program against a "grid API." I'm not aware of any advantages to tools which use the approach of an explicit API but would love to hear about them if they do in fact exist. :) I've also spent time reading about memcached but am more interested in hearing feedback on these three specific solutions. I would be curious to hear how they measure up against memcached in the event someone has used both.

  • Run shell script using fabric and piping script text to shell's stdin

    - by Peter Lyons
    Is there a way to execute a multi-line shell script by piping it to the remote shell's standard input in fabric? Or must I always write it to the remote filesystem, then run it, then delete it? I like sending to stdin as it avoids the temporary file. If there's no fabric API (and it seems like there is not based on my research), presumably I can just use the ssh module directly. Basically I wish fabric.api.run was not limited to a 1-line command that gets passed to the shell as a command line argument, but instead would take a full multi-line script and write it to the remote shell's standard input.

  • Rails: Accessing the username/password used for HTTP Basic Auth?

    - by Shpigford
    I'm building a basic API where user information can be retrieved after that user's login and password are correctly sent. Right now I'm using something like this: http://foo:[email protected]/api/user.xml So, what I need to do is access the user/password sent in the request (the foo and bar) but am not sure how to access that info in a Rails controller. Then I'd check those variables via a quick User.find and then set those as the username and password variables for authenticate_or_request_with_http_basic. It's possible I'm looking at this at the completely wrong way, but that's where I'm at right now. :)

  • How to transform vertical table into horizontal table?

    Hello, I have one table Person: Id Name 1 Person1 2 Person2 3 Person3 And I have its child table Profile: Id PersonId FieldName Value 1 1 Firstname Alex 2 1 Lastname Balmer 3 1 Email [email protected] 4 1 Phone +1 2 30004000 And I want to get data from these two tables in one row like this: Id Name Firstname Lastname Email Phone 1 Person1 Alex Balmer [email protected] +1 2 30004000 What is the most optimized query to get these vertical (key, value) values in one row like this? Now I have a problem that I done four joins of child table to parent table because I need to get these four fields. Some optimization is for sure possible. I would like to be able to modify this query in easy way when I add new field (key,value). What is the best way to do this? To create some StoreProcedure? I would like to have strongly types in my DB layer (C#) and using LINQ (when programming) so it means when I add some new Key, Value pair in Profile table I would like to do minimal modifications in DB and C# if possible. Actually I am trying to get some best practices in this case.

  • Passing variables to callback functions

    - by mickyjtwin
    I am trying to write a jQuery plugin, that can be applied to a selector. Within this plugin, there are multiple calls to webservices, where callback methods are required. The problem I am having is maintaining the current context item in the each loop of the selector. (function($){ $.fn.myMethod = function(){ return this.each(function(){ var c = $(this); $.api.methodToCall("", CallbackFunction); }); }; function CallbackFunction(data, result){ // do stuff based on c } })(jQuery); Normally, you would provide the callback function straight away, which allows me to access c, however within the callback function, there potentially is another api call, so it would start to get messy. Is there any way to do this?

  • BitShifting with BigIntegers in Java

    - by ThePinkPoo
    I am implementing DES Encryption in Java with use of BigIntegers. I am left shifting binary keys with Java BigIntegers by doing the BigInteger.leftShift(int n) method. Key of N (Kn) is dependent on the result of the shift of Kn-1. The problem I am getting is that I am printing out the results after each key is generated and the shifting is not the expected out put. The key is split in 2 Cn and Dn (left and right respectively). I am specifically attempting this: "To do a left shift, move each bit one place to the left, except for the first bit, which is cycled to the end of the block. " It seems to tack on O's on the end depending on the shift. Not sure how to go about correcting this.

  • Detecting when Bluetooth is disabled on iOS5

    - by Non Umemoto
    I'm developing blog speaker app. I wanna pause the audio when bluetooth is disabled like iPod app. I thought it's not possible without using private api after reading this. Check if Bluetooth is Enabled? But, my customer told me that Rhapsody and DI Radio apps both support it. Then I found iOS5 has Core Bluetooth framework. https://developer.apple.com/library/ios/documentation/CoreBluetooth/Reference/CoreBluetooth_Framework/CoreBluetooth_Framework.pdf CBCentralManagerStatePoweredOff status seems like the one. But, the description says this api only supports Bluetooth 4.0 low energy devices. Did anyone try doing the same thing? I want to support current popular bluetooth headsets, or bluetooth enabled steering wheel on the car. I don't know if it's worth trying when it only supports some brand new bluetooth.

  • Javascript problem with location.href.

    - by Patrick
    Hello! I have a textbox and whenever the user presses a key it's checked to see if the user pressed enter. If the enter key is pressed, i want to add all the info in the textbox and transfer the user to a different url. <script language="javascript" type="text/javascript"> function checkEnter(e){ //e is event object passed from function invocation var characterCode; if(e && e.which){ //if which property of event object is supported (NN4) e = e; characterCode = e.which; //character code is contained in NN4's which property } else{ e = event; characterCode = e.keyCode; //character code is contained in IE's keyCode property } if (characterCode == 13) { //if generated character code is equal to ascii 13 (if enter key) var searchLink = '/Search/?Keywords=' + document.getElementById('<%= searchBox.ClientID %>').value; transferUser(searchLink); return false; } else{ return true; } } function transferUser(url) { window.location.href = url; window.location.replace(url); } </script> Search: <input name="ctl00$searchBox" type="text" id="ctl00_searchBox" class="header_line_search_box_textbox" onKeyPress="checkEnter(event);" /> I have tried every possible combination, but nothing happens. The site just refreshes itself. I also need somehow to convert the text from the user to html safe, must like the HttpUtility.EncodeUrl in aspx.

  • Is it possible to group records belonging to an entity in dbunit?

    - by Joshua
    Our JPA entity model auto-generates primary key identifiers for user, user_address tables. Would it be possible to group these entities given below via dbunit, so that I don't need to provide neither the primary key as well as the foreign key reference from user_address.user_id. It is getting very hard to maintain these keys (i.e. I would prefer to group the primary record 'user' and the child records 'user_address' so that dbunit can group them automatically by looking up the entity metadata). Is it achievable? <user id="1" first_name="Josh" creation_date="2009-07-11 15:45:28"/> <user_address id="1" user_id="1" address="Main St" city="Los Angeles"/> I would prefer something like this <!-- First user --> <user first_name="Josh" creation_date="2009-07-11 15:45:28"/> <user_address address="Main St" city="Los Angeles"/> <!-- Second user --> <user first_name="Mary" creation_date="2009-07-11 15:45:28"/> <user_address address="Taylors St" city="San Jose"/>
