  • FMOD Compiling trouble

    - by CptAJ
    I'm trying to get started with FMOD but I'm having some issues compiling the example code in this tutorial: http://www.gamedev.net/reference/articles/article2098.asp I'm using MinGW, I placed the libfmodex.a file in MinGW's include folder (I also tried linking directly to the filename) but it doesn't work. Here's the output. C:\>g++ -o test1.exe test1.cpp -lfmodex test1.cpp:4:1: error: 'FSOUND_SAMPLE' does not name a type test1.cpp: In function 'int main()': test1.cpp:9:29: error: 'FSOUND_Init' was not declared in this scope test1.cpp:12:4: error: 'handle' was not declared in this scope test1.cpp:12:53: error: 'FSOUND_Sample_Load' was not declared in this scope test1.cpp:13:30: error: 'FSOUND_PlaySound' was not declared in this scope test1.cpp:21:30: error: 'FSOUND_Sample_Free' was not declared in this scope test1.cpp:22:17: error: 'FSOUND_Close' was not declared in this scope This is the particular example I'm using: #include <conio.h> #include "inc/fmod.h" FSOUND_SAMPLE* handle; int main () { // init FMOD sound system FSOUND_Init (44100, 32, 0); // load and play sample handle=FSOUND_Sample_Load (0,"sample.mp3",0, 0, 0); FSOUND_PlaySound (0,handle); // wait until the users hits a key to end the app while (!_kbhit()) { } // clean up FSOUND_Sample_Free (handle); FSOUND_Close(); } I have the header files in the "inc" path where my code is. Any ideas as to what I'm doing wrong?

  • Get the id of the link and pass it to the jQueryUI dialog widget

    - by Mike Sanchez
    I'm using the dialog widget of jQueryUI. Now, the links are grabbed from an SQL database by using jQuery+AJAX which is the reason why I used "live" $(function() { var $dialog = $('#report') .dialog({ autoOpen: false, resizable: false, modal: true, height: 410, width: 350, draggable: true }) //store reference to placeholders $uid = $('#reportUniqueId'); $('.reportopen').live("click", function (e) { $dialog.dialog('open'); var $uid = $(this).attr('id'); e.preventDefault(); }); }); My question is, how do I pass the id of the link that triggered the dialog widget to the dialog box itself? The link is set up like this: <td align="left" width="12%"> <span id="notes"> [<a href="javascript:void(0)" class="reportopen" id="<?=$reportId;?>">Spam</a>] </span> </td> And the dialogbox is set up like this: <div id="report" title="Inquire now"> HAHAHAHAHA <span id="reportUniqueId"></span> </div> I'd like for the id to be passed and generated in the <span id="reportUniqueId"></span> part of the dialog box. Any idea?

  • Another developer revoked and re-created my client's iOS Distribution Certificate - does this mean I can never update my client's existing app?

    - by Schnapple
    Here is the story so far: A client hired us to do an iPhone app for them. This client had never done an iPhone app before and as part of the arrangement we handled all aspects for them, including app store submission, and we handle some level of future development (new features, bug/security fixes, etc.) We created a Distribution certificate and key pair on the client's behalf We developed the app, published it to the App Store without incident Some time later the client hired a second developer to do a different app for them This second developer, it appears, has revoked the existing Distribution certificate and created a new one with a new key pair on their system This second developer shared the new Distribution certificate and key pair with us for future reference. Due to user error, this new certificate and key pair has now been imported onto the Macintosh where the original certificate and key pair for the original app we developed were created and the originals were not backed up. So we have App #1 on the App Store with Distribution certificate/key pair #1 App #2 either on the App Store or soon to be using Distribution certificate/key pair #2 Distribution certificate/key pair #1 appears to be lost now So my question is: if we ever need to update App #1, will we be able to, using Distribution certificate/key pair #2? Or will we have to upload it as a new app?

  • how to share a variable between two threads

    - by prmatta
    I just inherited some code, two threads within this code need to perform a system task. One thread should do the system task before the other thread. They should not be performing the system task together. The two threads do not have references to each other. Now, I know I can use some sort of a semaphore to achieve this. But my question is what is the right way to get both threads to access this semaphore. I could create a static variable/method a new class : public class SharedSemaphore { private static Semaphore s = new Semaphore (1, true); public static void performSystemTask () { s.acquire(); } public static void donePerformingSystemTask() { s.release(); } } This would work (right?) but this doesn't seem like the right thing to do. Because, the threads now have access to a semaphore, without ever having a reference to it. This sort of thing doesn't seem like a good programming practice. Am I wrong?

  • Can't diagnose my MySQL root user problem

    - by George Crawford
    Hi all, I have a problem with the MySQL root user in My MySQL setup, and I just can't for the life of me work out how to fix it. It seems that I have somehow messed up the root user, and my access to databases is now very erratic. For reference, I'm using MAMP on OS X to provide the MySQL server. I'm not sure how much that matters though - I'd guess that whatever I've done will require a command-line fix to solve it. I can start MySQL using MAMP as usual, and access databases using the 'standard' users I have created for my PHP apps. However, the root user, which I use in my MySQL GUI client, and also in phpMyAdmin, can only access the "information_schema" database, as well as two I have created manually, and presumably (and mistakenly) left permissions wide open for. My 15 or so other databases cannot be accessed my the root user. When I load up phpMyAdmin, the home screen says: "Create new database: No Privileges". I certainly did at some stage change my root user's password using the MAMP dialog. But I don't remember if I did anything else which might have caused this problem. I've tried changing the password again, and there seems to be no change in the issue. I've also tried resetting root password using the command line, including starting mysql manually with --skip-grant-tables then flushing privs, but again, nothing seems to fix the issue. I've come to the end of my ideas, and would very much appreciate some step-by-step advice and diagnosis from one of the experts here! Many thanks for your help.

  • ASP.NET Web Application: use 1 or multiple virtual directories

    - by tster
    I am working on a (largish) internal web application which has multiple modules (security, execution, features, reports, etc.). All the pages in the app share navigation, CSS, JS, controls, etc. I want to make a single "Web Application" project, which includes all the pages for the app, then references various projects which will have the database and business logic in them. However, some of the people on the project want to have separate projects for the pages of each module. To make this more clear, this is what I'm advocating to be the projects. /WebInterface* /SecurityLib /ExecutionLib etc... And here is what they are advocating: /SecurityInterface* /SecutiryLib /ExecutionInterface* /ExecutionLib etc... *project will be published to a virtual directory of IIS Basically What I'm looking for is the advantages of both approaches. Here is what I can think of so far: Single Virtual Directory Pros Modules can share a single MasterPage Modules can share UserControls (this will be common) Links to other modules are within the same Virtual directory, and thus don't need to be fully qualified. Less chance of having incompatible module versions together. Multiple Virtual Directories Pros Can publish a new version of a single module without disrupting other modules Module is more compartmentalized. Less likely that changes will break other modules. I don't buy those arguments though. First, using load balanced servers (which we will have) we should be able to publish new versions of the project with zero downtime assuming there are no breaking database changes. Second, If something "breaks" another module, then there is either an improper dependency or the break will show up eventually in the other module, when the developers copy over the latest version of the UserControl, MasterPage or dll. As a point of reference, there are about 10 developers on the project for about 50% of their time. The initial development will be about 9 months.

  • Xcode: how to know a header file is actually imported?

    - by Philip007
    To be specific, I am using RestKit framework. I want to use a framework class category called RKObjectManager+RKTableController in my view controller mainTVC. Here is my #import section in mainTVC.m: // framework headers, which should be enough #import <RestKit/RestKit.h> #import <RestKit/UI.h> // my project headers, not relating to framework #import "MainTVC.h" #import "Photo.h" // Do this to guarantee import does happen. But still got error, see below #import <RestKit/RKObjectManager+RKTableController.h> However, Xcode issue an error: No known class method for selector 'fetchRequest:groupedBy:inContext:' For reference, this method is a class method declared only in category header RKObjectManager+RKTableController.h, but not in 'RKObjectManager.h`. Also, I added -ObjC and -all_load to "other linker flags" in build settings, if that's relevant. I suspect the error is caused by the fact that category header is not actually imported somehow. How can I verify that? Or the error is caused by other reasons that I am not aware of. What am I doing wrong?

  • Trying to match variables in a PHP array

    - by Nick B
    I'm stuck with a php array problem. I've to a webpage that takes values from a URL, and I need to cross reference those values against some values on the page and if they match output a 'yes'. It's an expression engine bodge job. The URL is something like domain.com/page/C12&C14 The C12 and C14 represent different categories. I've taken the last bit of the url, removed the 'C' from the values and then exploded the 12&14 into an array. I print_r the array on the page and it shows: Array ( [0] = 12 [1] = 14 ) So, the values are in the array. Lovely. Now on the page I have an html list which looks like 10 12 14 15 I want to output a YES next to the variables that are current in the array so the ideal output would be: 10 12 - YES 14 - YES 15 I was trying this but it keeps just saying No next to all of them. $currentnumber = 12; foreach ($tharray as $element) { if ($element == $currentnumber) { echo "Yes"; } else { echo "No"; } } I thought that should work, but it's not. I checked and the array and the variable are both stings. I did a strlen() on both to see if they are the same, but $currentnumber outputs '13' and the array variable outputs '2'. Any ideas as to why it's saying 13? Is the variable the wrong type of string - and if so how would I convert it?

  • JVM to ignore certificate name mismatch

    - by Heavy Bytes
    I know there were a lot of questions/answers about how to ignore SSL error in the code. On our dev region dev.domain.tld we have configured a app server over SSL. The certificate that is displayed is for somedev.domain.tld. There is no way to change the certificate, it will always be a domain mismatch. So when I deploy a web-service to https://dev.domain.tld and try to connect/call my webservice I get an exception: Caused by: java.security.cert.CertificateException: No name matching dev.domain.tld found And I have the somedev.domain.tld CERT in my trust store. Now, I saw a lot of samples how to change that in the code (using a Trust Manager that accepts all domains), but how do I specify to the JVM to ignore the domain mismatch when connecting to the server? Is there a -Djavax.net.ssl argument or something? Thank you! UPDATE: Or, since I am using Spring-WS, is there a way to set some property in Spring for that? (WebServiceTemplate) UPDATE I guess I'll have to do use something from Spring Security: http://static.springsource.org/spring-ws/sites/1.5/reference/html/security.html

  • GWT - problems with constants in css

    - by hba
    Hi, I'm new to GWT; I'm building a small sample app. I have several CSS files. I'm able to successfully use the ClientBundle and CssResource to assign styles to the elements defined in my UiBinder script. Now I'd like to take it one step further and introduce CSS constants using @def css-rule. The @def works great when I define a constant and use it in the same CSS file. However I cannot use it in another CSS file. When I try to use the @eval rule to evaluate an existing constant the compiler throws an execption: "cannot make a static reference to the non-static method ". Here is an example of what I'm trying to do: ConstantStyle.css @def BACKGROUND red; ConstantStyle.java package abc; import ...; interface ConstantStyle extends cssResource { String BACKGROUND(); } MyStyle.css @eval BACKGROUND abc.ConstantStyle.BACKGROUND(); .myClass {background-color: BACKGROUND;} MyStyle.java package abc; import ...; interface ConstantStyle extends cssResource { String myClass; } MyResources.java package abc; import ...; interface MyResources extends ClientBundle { @Source("ConstantStyle.css") ConstantStyle constantStyle(); @Source("MyStyle.css") MyStyle myStyle(); } Thanks in advance!

  • What is the best cross-platform language for desktop applications? (Java, Adobe Air, Flex, Silverlight??, Anything Else)

    - by Sootah
    My business partner needs a desktop application programmed, and it needs to be cross-platform as he wants Mac owners (OS X) to be able to run it as well. This, of course, is a bit of a problem for me as I program in PHP for my web projects and exclusively in C# (formerly used Visual Basic) for my desktop apps. I've been using (and love) NetBeans for my PHP stuff, and love Visual Studio just as much; they're both excellent IDEs. With this in mind, I'd like to find a language and IDE that's as similar to Visual Studio as possible (or at least something that makes development as easy as it does) for my cross-platform application development. In fact, if there is a language I can use with VS I'd be extremely happy. I realize that NetBeans has a Java Desktop App IDE, but have been having problems with it (my question in regards to that issue is here. I am also not sure that I really want to learn and use Java if there is a better, easier option out there. Obviously, the first language that came to mind that I can use cross-platform was Java, but I've also heard of people using Adobe Air, as well as Flex being used. I've never programmed in any of those languages, and as such have no frame of reference from which I can decide which would be best for me. I'm also not sure what other options there may be for me; perhaps there's another language I can use that'd be better than the three options I've already provided. (Can you make desktop apps with Silverlight? If so, did MS make an interpreter that will get them to work on OS X?) I like the syntax of C# quite a bit, and the Visual Studio IDE makes it extremely easy to make my apps with. As such, I'd like to find something that'll work as well for me with the cross-platform shatner as C# and its IDE does with my Windows apps. Thanks in advance for your help/opinions!

  • Can we manipulate (subtract) the value of a property while template bidning?

    - by Subhen
    Hi, I am currently defining few grids as following: <Grid.RowDefinitions> <RowDefinition Height="{TemplateBinding Height-Height/5}"/> <RowDefinition Height="{TemplateBinding Height/15}"/> <RowDefinition Height="{TemplateBinding Height/20}"/> <RowDefinition Height="{TemplateBinding Height/6}"/> </Grid.RowDefinitions> While the division works fine , the subtraction isn't yielding the output. Ialso tried like following: <RowDefinition Height="{TemplateBinding Height-(Height/5)}"/> Still no result. Any suggestions plz. Thanks, Subhen ** Update ** Now In My XAML I tried implementing the IvalueConverter like : <RowDefinition Height="{TemplateBinding Height, Converter={StaticResource heightConverter}}"/> Added the reference as <local:medieElementHeight x:Key="heightConverter"/> In side generic.cs I have coded as following: public class medieElementHeight : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { //customVideoControl objVdeoCntrl=new customVideoControl(); double custoMediaElementHeight = (double)value;//objVdeoCntrl.customMediaPlayer.Height; double mediaElementHeight = custoMediaElementHeight - (custoMediaElementHeight / 5); return mediaElementHeight; } #region IValueConverter Members object IValueConverter.ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } #endregion } But getting the exception Unknown Element Height in the element RowDefination.

  • How can I accelerate the generation of the an MD5 Checksum within vb.net?

    - by Richard
    I'm working with some very large files residing on P2 (Panasonic) cards. Part of the process we employ is to first generate a checksum of the file we are going to copy, then copy the file, then run a checksum on the file to confirm that it copied OK. The problem is, is that files are large (70 GB+) and take a long time to complete. It's an issue since we will eventually be dealing with thousands of these files. I would like to find a faster way to generate the checksum other than using the System.Security.Cryptography.MD5CryptoServiceProvider I don't care if this means using a specialized hardware card, provided it works and is not to ungodly expensive. I would prefer to have a method of encoding that provided some feedback as to how far the process has gone along so I can display it like I do now. The application is written in vb.net. I would prefer to be able to use it as component, library, reference within my application, but I'm willing to call an outside application if there is enough improvement in the speed of generating the checksum. Needless to say, the checksum must be consistent and correct. :-) Thank you in advance for your time and efforts, Richard

  • Moving from NHibernate to FluentNHibernate: assembly error (related to versions)?

    - by goober
    Not sure where to start, but I had gotten the most recent version of NHibernate, successfully mapped the most simple of business objects, etc. When trying to move to FluentNHibernate and do the same thing, I got this error message on build: "System.IO.FileLoadException: Could not load file or assembly 'NHibernate, Version=2.1.0.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference." Background: I'm new to Hibernate, NHibernate, and FluentNHibernate -- but not to .NET, C#, etc. Database I have a database table called Category: (PK) CategoryID (type: int), unique, auto-incrementing UserID (type: uniqueidentifier) -- given the value of the user Guid in ASP.NET database Title (type: varchar(50) -- the title of the category Components involved: I have a SessionProviderClass which creates the mapping to the database I have a Category class which has all the virtual methods for FluentNHibernate to override I have a CategoryMap : ClassMap class, which does the fluent mappings for the entity I have a CategoryRepository class that contains the method to add & save the category I have the TestCatAdd.aspx file which uses the CategoryRepository class. Would be happy to post code for any of those, but I'm not sure that it's necessary, as I think the issue is that somewhere there's a version conflict between what FluentNHibernate references and the NHibernate I have installed from before. Thanks in advance for any help you can give!

  • Castle Windsor: Reuse resolved component in OnCreate, UsingFactoryMethod or DynamicParameters

    - by shovavnik
    I'm trying to execute an action on a resolved component before it is returned as a dependency to the application. For example, with this graph: public class Foo : IFoo { } public class Bar { IFoo _foo; IBaz _baz; public Bar(IFoo foo, IBaz baz) { _foo = foo; _baz = baz; } } When I create an instance of IFoo, I want the container to instantiate Bar and pass the already-resolved IFoo to it, along with any other dependencies it requires. So when I call: var foo = container.Resolve<IFoo>(); The container should automatically call: container.Resolve<Bar>(); // should pass foo and instantiate IBaz I've tried using OnCreate, DynamicParameters and UsingFactoryMethod, but the problem they all share is that they don't hold an explicit reference to the component: DynamicParameters is called before IFoo is instantiated. OnCreate is called after, but the delegate doesn't pass the instance. UsingFactoryMethod doesn't help because I need to register these components with TService and TComponent. Ideally, I'd like a registration to look something like this: container.Register<IFoo, Foo>((kernel, foo) => kernel.Resolve<Bar>(new { foo })); Note that IFoo and Bar are registered with the transient life style, which means that the already-resolved instance has to be passed to Bar - it can't be "re-resolved". Is this possible? Am I missing something?

  • Why does grails use hsqldb when I ask for mysql?

    - by John
    I'm following the racetrack example from Jason Rudolph's book at InfoQ, using grails-1.2.1. I got up to the part where I was to switch from hsqldb to mysql. I think I've deleted every reference to hsqldb in the DataSource.groovy file, but I get an exception and the stack trace shows it's still using hsqldb. DataSource.groovy dataSource { boolean pooled = true String driverClassName = "com.mysql.jdbc.Driver" String url = "jdbc:mysql://localhost/dfpc2" String dbCreate = "create" String username = "dfpc2" String password = "dfpc2" dialect = org.hibernate.dialect.MySQL5InnoDBDialect } hibernate { cache.use_second_level_cache=true cache.use_query_cache=true cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' } // environment specific settings environments { development { } test { } production { } } When I grails run-app it all starts up with no errors. I can navigate to the home page.

I've tried grails clean I tried putting the dataSource info in the development environment (I haven't graduated to test or prod yet), but it seemed to make no difference. The stdout shows I'm using development env. I've googled for solutions, but the only solution I've found is when people don't change the test or production environments.

  • NSDrawer delegate pointing to deallocated object?

    - by Isaac
    A user has sent in a crash report with the stack trace listed below (I have not been able to reproduce the crash myself, but every other crash this user has reported has been a valid bug, even when I couldn't reproduce the effect). The application is a reference-counted Objective-C/Cocoa app. If I am interpreting it correctly, the crash is caused by attempting to send a drawerDidOpen: message to a deallocated object. The only object that should be receiving drawerDidOpen: is the drawer's delegate object (nowhere does any object register to receive drawer notifications), and the drawer's delegate object is instantiated via the XIB/NIB file, wired to the delegate outlet of the drawer, and not referenced anywhere else. Given that, how can I protect against the delegate getting dealloc'd before the drawer notification? Or, alternately, what have I misinterpreted that might be causing the crash? Crash log/stack trace: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000010 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Application Specific Information: objc_msgSend() selector name: drawerDidOpen: Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x00007fff8272011c objc_msgSend + 40 1 com.apple.Foundation 0x00007fff87d0786e _nsnote_callback + 167 2 com.apple.CoreFoundation 0x00007fff831bcaea __CFXNotificationPost + 954 3 com.apple.CoreFoundation 0x00007fff831a9098 _CFXNotificationPostNotification + 200 4 com.apple.Foundation 0x00007fff87cfe7d8 -[NSNotificationCenter postNotificationName:object:userInfo:] + 101 5 com.apple.AppKit 0x00007fff8512e944 _NSDrawerObserverCallBack + 840 6 com.apple.CoreFoundation 0x00007fff831d40d7 __CFRunLoopDoObservers + 519 7 com.apple.CoreFoundation 0x00007fff831af8c4 CFRunLoopRunSpecific + 548 8 com.apple.HIToolbox 0x00007fff839b8ada RunCurrentEventLoopInMode + 333 9 com.apple.HIToolbox 0x00007fff839b883d ReceiveNextEventCommon + 148 10 com.apple.HIToolbox 0x00007fff839b8798 BlockUntilNextEventMatchingListInMode + 59 11 com.apple.AppKit 0x00007fff84de8a2a _DPSNextEvent + 708 12 com.apple.AppKit 0x00007fff84de8379 -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 155 13 com.apple.AppKit 0x00007fff84dae05b -[NSApplication run] + 395 14 com.apple.AppKit 0x00007fff84da6d7c NSApplicationMain + 364 15 (my app's identifier) 0x0000000100001188 start + 52

  • XSD: Different sub-elements depending on attribute/element value

    - by AndiDog
    Another XSD question - how can I achieve that the following XML elements are both valid: <some-element> <type>1</type> <a>...</a> </some-element> <some-element> <type>2</type> <b>...</b> </some-element> The sub-elements (either <a> or <b>) should depend on the content of <type> (could also be an attribute). It would be so simple in RelaxNG - but RelaxNG doesn't support key integrity :( Is there a way to implement this in XSD? Note: XML schema version 1.1 supports <xs:alternative>, which might be a solution, but afaik no reference implementation (e.g. libxml2) supports this yet. So I'm searching for workarounds. The only way I've come up with is: <type>1</type> <some-element type="1"> <!-- simple <xs:choice> between <a> and <b> goes here --> <a>...</a> </some-element> <!-- and now create a keyref between <type> and @type -->

  • Setting synthesized arrays causing memory leaks using nested arrays

    - by webtoad
    Hello: Why is the following code causing a memory leak in an iPhone App? All of the initted objects below leak, including the arrays, the strings and the numbers. So, I'm thinking it has something to do with the the synthesized array property not releasing the object when I set the property again on the second and subsequent time this piece of code is called. Here is the code: "controller" (below) is my custom view controller class, which I have a reference to, and I am setting with this code snippet: sqlite3_stmt *statement; NSMutableArray *foo_IDs = [[NSMutableArray alloc] init]; NSMutableArray *foo_Names = [[NSMutableArray alloc] init]; NSMutableArray *foo_IDsBySection = [[NSMutableArray alloc] init]; NSMutableArray *foo_NamesBySection = [[NSMutableArray alloc] init]; // Get data: NSString *sql = @"select distinct p.foo_ID, p.foo_Name from foo as p "; if (sqlite3_prepare_v2(...) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { int p_id; NSString *foo_Name; p_id = sqlite3_column_int(statement, 0); char *str2 = (char *)sqlite3_column_text(statement, 1); foo_Name = [NSString stringWithCString:str2]; [foo_IDs addObject:[NSNumber numberWithInt:p_id]]; [foo_Names addObject:foo_Name]; } sqlite3_finalize(statement); } // Pass the array itself into another array: // (normally there is more than one array in each array) [foo_IDsBySection addObject: foo_IDs]; [foo_NamesBySection addObject: foo_Names]; [foo_IDs release]; [foo_Names release]; // Set some synthesized properties (of type NSArray, nonatomic, // retain) in controller: controller.foo_IDsBySection = foo_IDsBySection; controller.foo_NamesBySection = foo_NamesBySection; [foo_IDsBySection release]; [foo_NamesBySection release]; Thanks for any help!

  • Fluent NHibernate - How to map the foreign key column as a property

    - by Steve
    I am sure this is a straightforward question but consider the following: I have a reference between company and sector as follows: public class Company { public Guid ID { get; set; } public Sector Sector { get; set; } public Guid SectorID { get; set; } } public class Sector { public Guid ID { get; set; } public string Name { get; set; } } Ok. What I want is the SectorID of the Company object to be populated after I go: (new Company()).Sector = new Sector() { Name="asdf" } and do a flush. The mapping I am using kindly creates an additional column in the database called Sector_Id in the Company table, but this is not available as a property on Company. I want the SectorID property to be filled. The mapping i am currently using in the CompanyMap is References(c = c.Sector).Cascade.All(); Does anyone have any ideas?

  • Const_cast on a this pointer - would I get told off by other C++ coders for doing this?

    - by BeeBand
    I have a class Game e.g. class Game { public: InitObjects(); ... }; And I have another class Grid, that needs to be initialised with a non-const reference to that Game object. ( A Grid object needs to call functions that can update a Game object ). class Grid { public: Grid(Game & g): game(g){} ... private: Game & game; ... }; The Game object is responsible for initialising the Grid. I did this: void Game::InitObjects() { grid = new Grid(*(const_cast<Game*>(this)) ); } grid is not a member of a Game - it's a global ( argh - i know... I don't mind making it a member, but I have the same problem right? ). Can some seasoned C++ folk tell me if this odd looking const_cast is acceptable?

  • asp.net MVC ActionMethod causing null exception on parameter

    - by David Liddle
    I am trying to add filter functionality that sends a GET request to the same page to filter records in my table. The problem I am having is that the textbox complains about null object reference when a parameter is not passed. For example, when the person first views the page the url is '/mycontroller/myaction/'. Then when they apply a filter and submit the form it should be something like 'mycontroller/myaction?name=...' Obviously the problem stems from when the name value has not been passed (null) it is still trying to be bound to the 'name' textbox. Any suggestions on what I should do regarding this problem? UPDATE I have tried setting the DefaultValue attribute but I am assuming this is only for route values and not query string values ActionResult MyAction([DefaultValue("")] string name) //Action - /mycontroler/myaction ActionResult MyAction(string name) { ...do stuff } //View <div id="filter"> <% Html.BeginForm("myaction", "mycontroller", FormMethod.Get); %> Name: <%= Html.TextBox("name") %> .... </div> <table>...my list of filtered data

  • How to force inclusion of an object file in a static library when linking into executable?

    - by Brian Bassett
    I have a C++ project that due to its directory structure is set up as a static library A, which is linked into shared library B, which is linked into executable C. (This is a cross-platform project using CMake, so on Windows we get A.lib, B.dll, and C.exe, and on Linux we get libA.a, libB.so, and C.) Library A has an init function (A_init, defined in A/initA.cpp), that is called from library B's init function (B_init, defined in B/initB.cpp), which is called from C's main. Thus, when linking B, A_init (and all symbols defined in initA.cpp) is linked into B (which is our desired behavior). The problem comes in that the A library also defines a function (Af, defined in A/Afort.f) that is intended to by dynamically loaded (i.e. LoadLibrary/GetProcAddress on Windows and dlopen/dlsym on Linux). Since there are no references to Af from library B, symbols from A/Afort.o are not included into B. On Windows, we can artifically create a reference by using the pragma: #pragma comment (linker, "/export:_Af") Since this is a pragma, it only works on Windows (using Visual Studio 2008). To get it working on Linux, we've tried adding the following to A/initA.cpp: extern void Af(void); static void (*Af_fp)(void) = &Af; This does not cause the symbol Af to be included in the final link of B. How can we force the symbol Af to be linked into B?

  • Haskell Cons Operator (:)

    - by Carson Myers
    I am really new to Haskell (Actually I saw "Real World Haskell" from O'Reilly and thought "hmm, I think I'll learn functional programming" yesterday) and I am wondering: I can use the construct operator to add an item to the beginning of a list: 1 : [2,3] [1,2,3] I tried making an example data type I found in the book and then playing with it: --in a file data BillingInfo = CreditCard Int String String | CashOnDelivery | Invoice Int deriving (Show) --in ghci $ let order_list = [Invoice 2345] $ order_list [Invoice 2345] $ let order_list = CashOnDelivery : order_list $ order_list [CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, ...- etc... it just repeats forever, is this because it uses lazy evaluation? -- EDIT -- okay, so it is being pounded into my head that let order_list = CashOnDelivery:order_list doesn't add CashOnDelivery to the original order_list and then set the result to order_list, but instead is recursive and creates an infinite list, forever adding CashOnDelivery to the beginning of itself. Of course now I remember that Haskell is a functional language and I can't change the value of the original order_list, so what should I do for a simple "tack this on to the end (or beginning, whatever) of this list?" Make a function which takes a list and BillingInfo as arguments, and then return a list? -- EDIT 2 -- well, based on all the answers I'm getting and the lack of being able to pass an object by reference and mutate variables (such as I'm used to)... I think that I have just asked this question prematurely and that I really need to delve further into the functional paradigm before I can expect to really understand the answers to my questions... I guess what i was looking for was how to write a function or something, taking a list and an item, and returning a list under the same name so the function could be called more than once, without changing the name every time (as if it was actually a program which would add actual orders to an order list, and the user wouldn't have to think of a new name for the list each time, but rather append an item to the same list).

  • Webkit browsers rendering CSS different than Mozilla Firefox...Why??

    - by JAG2007
    I'm styling a form that was already marked up (made some markup changes), and I normally work in Firefox to style so I can use firebug and the web developer toolbar. On this project, I noticed that my styles are displaying quite differently for one particular area (several elements) in webkit based browsers Chrome and Safari, than in Firefox (we won't even get into Internet Explorer, although it is siding with the Firefox display). I can't figure out though why the styles are displaying so differently. Normally there is some rule that I'm neglecting that Firefox just takes for granted, and the others need it specified. But here I'm not getting why it's displaying this way. In particular I'm referring to the bottom area of the form where users can enter their contact info, then submit the form. I'll attach screen shots for reference as to the discrepancy. Here's the URL so feel free to check it out on your own. Although be advised that this is a production page (already released) so if you try out the form, you WILL BE added to CURE's contact database. http://www.helpcurenow.org/survey2010 Here's the screen shots: Firefox (the way I intend it to look) Chrome, and then Safari - strange change to submit button As a bonus, if anybody wants to help me with figuring out why on earth IE7 wants to not show the background behind the questions only, and how to fix that I would be much obliged! Thanks very much.
