  • ASP.NET check if LinqToEntities returned something or not.

    - by Alex
    How to make this method return boolean value, depending on query return. False - nothing, True - data exists. Before i just returned int from uniqueQuote.Count() but does not look like great method. Thank you! private bool CheckEnquiryUser(int enquiryId, Guid userId) { int selectedEnquiryId = enquiryId; Guid currentUserId = userId; Entities ctx3 = new Entities(); var uniqueQuote = from quot in ctx3.Enquiries.Include("aspnet_Users") where quot.EnquiryId == selectedEnquiryId && quot.aspnet_Users.UserId == currentUserId select quot; bool exist = uniqueQuote; return exist;

  • Troubles with NSString writeToFile

    - by Jesse
    Hi everyone, I have been working on a simple text editor in Cocoa/Objective-C for a practice project and I have come across an error that I would never have expected. I have an NSString for my file's contents as well as an NSString for it's path. When I attempt to write the contents to a file, I use the following method: [FileContents writeToFile: CurrentFileName atomically: NO encoding: NSStringEncoding error: nil]; I've used this method many times without error yet today, I am getting an error: "Expected expression before 'NSStringEncoding'" If anyone can help me out with this it would be greatly appreciated. I can't figure out what could be causing the error. Thanks a lot!

  • TDD, Unit Test and architectural changes

    - by Leandro
    I'm writing an RPC middleware in C++. I have a class named RPCClientProxy that contains a socket client inside: class RPCClientProxy { ... private: Socket* pSocket; ... } The constructor: RPCClientProxy::RPCClientProxy(host, port) { pSocket = new Socket(host, port); } As you can see, I don't need to tell the user that I have a socket inside. Although, to make unit tests for my proxies it would be necessary to create mocks for sockets and pass them to the proxies, and to do so I must use a setter or pass a factory to the sockets in the proxies's constructors. My question: According to TDD, is it acceptable to do it ONLY because the tests? As you can see, these changes would change the way the library is used by a programmer.

  • Objective C memory management question with NSArray

    - by Robert
    I am loading an array with floats like this: NSArray *arr= [NSArray arrayWithObjects: [NSNumber numberWithFloat:1.9], [NSNumber numberWithFloat:1.7], [NSNumber numberWithFloat:1.6], [NSNumber numberWithFloat:1.9],nil]; Now I know this is the correct way of doing it, however I am confused by the retail counts. Each Object is created by the [NSNumber numberWithFloat:] method. This gives the object a retain count of 1 dosnt it? - otherwise the object would be reclaimed The arrayWithObjects: method sends a retain message to each object. This means each object has a retain cont of 2. When the array is de-allocated each object is released leaving them with a retain count of 1. What have I missed?

  • How to secure an API written in .Net

    - by The Diamond Z
    This is a variation on an existing question in SO about securing/obfuscating .Net applications in general. I'm developing an API in C# that includes some algorithms I'm keen to protect. I understand no method will be perfect, but what's the generally accepted method for doing this? I'd like my clients to be able to code against the API but I don't want them to reverse engineer what's inside (at least I don't want to make it easy for them). If I obfuscate the code, won't that also obfuscate the API? We're looking at smartAssembly any thoughts comments on the product would be appreciated.

  • What is the difference between these two ways of creating NSStrings?

    - by adame
    NSString *myString = @"Hello"; NSString *myString = [NSString stringWithString:@"Hello"]; I understand that using method (1) creates a pointer to a string literal that is defined as static memory (and cannot be deallocated) and that using (2) creates an NSString object that will be autoreleased. Is using method (1) bad? What are the major differences? Is there any instances where you would want to use (1)? Is there a performance difference? P.S. I have searched extensively on Stack Overflow and while there are questions on the same topic, none of them have answers to the questions I have posted above.

  • control.focus() after selectedIndexChanged

    - by kyle
    I need to focus on a textbox after an item has been selected from a dropdownlist. I've tried control.focus() and setfocus(). The last thing I've tried was Set_Focus(dtbEffectiveDate.ClientID) inside the SelectedIndexChanged method with the folowing method. Protected Sub Set_Focus(ByVal ControlName As String) Dim strScript As String strScript = "<script language=javascript> window.setTimeout(""" + ControlName + ".focus();"",0); </script>" RegisterStartupScript("focus", strScript) End Sub I'm out of answers so any help would be awesome.

  • Problem with jQuery animation

    - by Daemon
    I have a problem with an animation in jQuery using ajax. On the click of an button (actually an tag), I call a ajax method, and have the following written inside the success parameter: success: function(msg) { $('.ContentsMainRight').children().fadeOut(500, function() { $('.ContentsMainRight').html(msg.d); $('.ContentsMainRight').children().fadeIn(1000); }); }, This have the following result. The contents of a div fade out over 500ms as it's supposed to. Then the html contents of the div are swapped, but then the last part did not work as I hoped. The html returned by the ajax method include some text inside a tag, and a image inside a tag. The result is that the text is automatically displayed instantly with no fadein, but the img that is put fades in over 1 second. Why is the text and image treated differently? -Daemon

  • Extendable accessing of sqlite database on android platform

    - by mscriven
    Hi, I am fairly new to the android sdk and databases and have been searching for an answer to this quite some time. I am trying to build an app which has multiple tables within a database. e.g. one for weapons, armours etc. However, my DatabaseManager class which handles all of my table creating, DatabaseHelper inner class and populating of data is creating for an extremely large class requiring high maintenance. Every time I would like to add or remove a table column I need to change quite a few areas of code, - Every reference to the addition of a row in that table with data - The method that the above calls - The method returning all of the database rows - The code in the helper class creating the table - Any specific update methods My question is this: Surely there must be some better way of coding this system, maybe using a database isn't the best way to go, or am i just not used to such large classes having only learned java at university and my largest class consisting of a mere 400-600 lines of code. Thanks for any help!

  • Facebook: Requires a valid user is specified (either via the session or via the API parameter for specifying the user.

    - by Stoic
    Hey Everyone, I am receiving this error: Requires a valid user is specified (either via the session or via the API parameter for specifying the user. when I am trying to utilize Facebook's FB.api with JS SDK for method: users.hasAppPermission I am constantly receiving this error, for any uid I pass on. Here is my code: $(document).ready(function() { var perms_requested = <?php echo PERMS;?>; var user_id = <?=$user_id;?>; $('#perms_check').html(loading); ask_for_perms(perms_requested, function(data) { $('#perms_check').html(data); }); function ask_for_perms(perms_requested,cb) { var request = []; $.each(perms_requested,function(i,permission) { FB.api({ method: 'users.hasAppPermission', ext_perm: permission, uid: user_id }, function(response) { if (response == 0) request.push(permission); if (i == perms_requested.length - 1) cb(request.join(', ')); }); }); } }); Also, I am utilizing nearly the same code in some other part of the same application, and I am getting fine results with that.

  • Is there a Javadoc-like plugin for Xcode that automatically generates the doc template?

    - by Mark
    I'm aware of Doxygen to generate the documentation. What I'm looking for is quick way to insert documentation in Xcode similar to what Eclipse does when editing Java files. Let's say I have an objective-c method with a couple of arguments like this: -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {... In Eclipse, if you place the cursor above the method and type: /**<Enter> you get a Javadoc template pre-populated with @param and @return tags. Is it possible to achieve something similar in Xcode? After typing /**<Enter>, I'd like to get this automatically: /** * * @param one * @param two * * @return */ -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {...

  • Searching for URL's Relative to Site Root in Javascript Source

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

  • Java: empty ArrayLists in a foor loop

    - by Patrick
    hi, I'm reusing the same ArrayList in a for loop, and I use for loop results = new ArrayList<Integer>(); experts = new ArrayList<Integer>(); output = new ArrayList<String>(); .... to create new ones. I guess this is wrong, because I'm allocating new memory. Is this correct ? If yes, how can I empty them ? Added: another example I'm creating new variables each time I call this method. Is this good practice ? I mean to create new precision, relevantFound.. etc ? Or should I declare them in my class, outside the method to not allocate more and more memory ? public static void computeMAP(ArrayList results, ArrayList experts) { //compute MAP double precision = 0; int relevantFound = 0; double sumprecision = 0; thanks

  • Avoiding sub-type selection in view code

    - by John Donoghue
    Hi, I have some code where the model contains some classes like (vb.net pseudocode, but could be any OO language): Enum AttributeType Boolean Date String End Enum MustInherit Class Attibute Must Override Function Type As AttributeType End Class Class BooleanAttribute: Attribute Function Type As AttributeType Return AttributeType.Boolean End Function End Class And the view contains some code like: Select Case AttributeType Case Boolean //Display checkbox control Case Date //Display date picker control Case String //Display textbox control End Select I don't really like the code in the view, for the hopefully obvious reasons (what happens when I get a new attribute type etc). My question is, how should I replace it? I could easily add a method to the concrete classes, but that pollutes the model with UI stuff so that's a horrible idea. I could move the select into a factory, but that seems to be just hiding the problem. Can anybody advise a better approach?

  • How can I double-enhance a class with cglib?

    - by artemb
    Hi there! Here's the code: Patient patient = factory.createPatient(); Enhancer enhancer = new Enhancer(); enhancer.setSuperclass(patient.getClass()); enhancer.setCallback(new DefaultMethodInterceptor(patient)); patient = (Patient) enhancer.create(); assertThat(patient.getFirstName()).isNotNull(); Enhancer enhancer2 = new Enhancer(); enhancer2.setSuperclass(patient.getClass()); enhancer2.setCallback(new DefaultMethodInterceptor(patient)); patient = (Patient) enhancer2.create(); assertThat(patient.getFirstName()).isNotNull(); It fails on the last assert with net.sf.cglib.core.CodeGenerationException: java.lang.reflect.InvocationTargetException-->null ... Caused by: java.lang.reflect.InvocationTargetException ... Caused by: java.lang.ClassFormatError: Duplicate method name&signature in class file my/package/entity/Patient$$EnhancerByCGLIB$$ca1e6685$$EnhancerByCGLIB$$f52743be I ask this because I want to enhance Hibernate's entities, but sometimes it returns already enhanced ones by itself and my second enhancement fails. How can I avoid this?

  • What is a 'best practice' backup plan for a website?

    - by HollerTrain
    I have a website which is very large and has a large user-base. I am trying to think of a 'best practice' way to create a back up or mirror website, so if something happens on domain.com, I can quickly point the site to backup.domain.com via 401 redirect. This would give me time to troubleshoot domain.com while everyone is viewing backup.domain.com and not knowing the difference. Is my method the ideal method, or have you enacted better methods to creating a backup site? I don't want to have the site go down and then get yelled at every minute while I'm trying to fix it. Ideally I would just 'flip the switch' and it would redirect the user to a backup. Any insight would be greatly appreciated.

  • Specifying Locations relative to the context XML in Spring

    - by Daisuke Shimamoto
    Is there a way to reference a properties file relative to the Spring's context file itself? What I want to do is the below: <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <!-- I want the below to be relative to this context XML file. --> <value>app.properties</value> </list> </property> </bean> I was imagining something like ${contextpath} that I could prepend to the above "app.properties" but couldn't find anything helpful. Thanks.

  • Android SurfaceView/Canvas flickering after trying to clear it

    - by Mark D
    So I am trying to clear the Canvas using canvas.drawColor(Color.BLACK) but if I just call this once, the display flickers and displays the old drawing which should have been covered up by the drawColor. Here is the important bits of my code - public void update() { //This method is called by a Thread Canvas canvas = holder.lockCanvas(null); if (canvas != null) { onDraw(canvas); } holder.unlockCanvasAndPost(canvas); } @Override protected void onDraw(Canvas canvas) { if (toClear) { canvas.drawColor(Color.BLACK); //if this is not set to change back to false, it does not flicker toClear = false; } //Draw some objects that are moving around } public void clearScreen() { //This method is called when the user pressed a button toClear = true; } After Googling around a litte, I heard about double buffering but came to the understanding that lockCanvas() and unlockCanvasAndPost() should handle this for me. What is going wrong here?

  • GCC compiler -- bug or unspecified behavior?

    - by Jared P
    When I have conflicting definitions of the ivars of a class in objective-c (not redeclaring the class in the same file, but rather naming the same class with diff ivars, no warnings or better yet errors are issued by the compiler. However, both sets of ivars are useable by the appropriate methods in the respective files. For instance Foo.m: @interface foo { int a; } - (int)method; @end @implementation foo - (int)method { return a; } @end Bar.m: @interface foo { float baz; } @end @implementation foo (category) - (float)blah { return baz; } @end compiles without warnings or errors. Is this intentional? Is this an unchecked error? (for the record, a and baz are actually the same memory location.)
