  • ASP.NET MVC Json Enum

    - by IceHeat
    public class Member { public string Name { get; set; } public Role Role { get; set; } } public enum Role { Plumber } public JsonResult GetMember() { Member member = new Member(); member.Name = "Joe the Plumber"; member.Role = Role.Plumber; return Json(member); } The Json always resolves the enum "Role" as 0,despite its value. What is the quickest way to get the string representation?

  • Can I prevent window.onbeforeunload from being called when doing an AJAX call

    - by Paul
    I have an AJAX-based grid control. We hook into the window.onbeforeunload event to check if they have unsaved data and if so present them with a message "Are you sure you want to navigate away...you have unsaved data...". All this is good. But AJAX calls also trigger window.onbeforeunload and so if the grid has unsaved data and we make an AJAX call (such as to delete a row in another grid) the user gets the "Are you sure you want to navigate away...you have unsaved data..." message which is not good. Is it possible to suppress the onbeforeunload event for AJAX calls? Or is it possible to detect that a call is an AJAX call? Otherwise we'll have to get hacking! Thanks

  • Zend Studio Debugger returns Application Error

    - by Keyne
    When I run debug for my public/index.php I got an application error as output. I've seen that it occurs at this line: foreach($feed->findFeedEntries($entriesLimit) as $entry) If I put a breakpoint before this, all works as expected, I mean, the error is after the line above. If I remove findFeedEntries() method, I can perform debugging without erros. To clarify, this method is in my row object as described bellow: This is the error <?php class Model_DbTable_FeedEntries extends Zf_Db_Table { public function fetchNewEntries($feed_id) { $Feeds = new Model_DbTable_Feeds(); $Feed = $Feeds->getById($feed_id); // ERROR IS HERE! The colum doesn't exists! // And this is only on zend-debugger!!! var_dump($Feed->link) // ... } } I'm completely lost about what's happening, once my application has no errors, the problem is with zend-debugger. The error is: An error occurred Application error Exception information: Message: Specified column "link" is not in the row Stack trace: #0 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(75): Zend_Db_Table_Row_Abstract->__get('link') #1 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(50): Model_DbTable_FeedEntries->fetchNewEntries('1') #2 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\Row\Feed.php(15): Model_DbTable_FeedEntries->getAllByFeedId('1', 1) #3 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\modules\default\controllers\IndexController.php(41): Model_DbTable_Row_Feed->findFeedEntries(1) #4 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Action.php(513): IndexController->indexAction() #5 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Dispatcher\Standard.php(289): Zend_Controller_Action->dispatch('indexAction') #6 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Front.php(954): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #7 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application\Bootstrap\Bootstrap.php(97): Zend_Controller_Front->dispatch() #8 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application.php(366): Zend_Application_Bootstrap_Bootstrap->run() #9 C:\Program Files\xampp\htdocs\desenvolvimentistas\public\index.php(54): Zend_Application->run() #10 C:\Users\RAPOSO\AppData\Local\Temp\dummy.php(1): include('C:\Program File...') #11 {main} I've notice that when I get the row object my colums names are not right.

  • ASP.NET MVC 2 validation LINQ to SQL

    - by Chino
    Currently I have a DataModel object which contains my linq to sql classes(a dmbl file). Currently I use a partial class to validate the incoming input. For example public partial class User : IEntity { public NameValueCollection CheckModel() { return GetRuleViolations(); } /// <summary> /// Method validates incoming data, by given rules in the if statement. /// </summary> /// <returns>NameValueCollection</returns> private NameValueCollection GetRuleViolations() { NameValueCollection errors = new NameValueCollection(); if (string.IsNullOrEmpty(Username)) errors.Add("Username", "A username is required"); // and so on return errors; } } Now what I want to try to do is add validation attributes to the fields. For example I want to try to add the required attribute to the field Username instead/in addtion of using the validation I currently have. My question is how can I achieve this because the dmbl file is auto generated. Or maybe it is not possible and should I use a different approach?

  • CSG operations on implicit surfaces with marching cubes [SOLVED]

    - by Mads Elvheim
    I render isosurfaces with marching cubes, (or perhaps marching squares as this is 2D) and I want to do set operations like set difference, intersection and union. I thought this was easy to implement, by simply choosing between two vertex scalars from two different implicit surfaces, but it is not. For my initial testing, I tried with two spheres circles, and the set operation difference. i.e A - B. One circle is moving and the other one is stationary. Here's the approach I tried when picking vertex scalars and when classifying corner vertices as inside or outside. The code is written in C++. OpenGL is used for rendering, but that's not important. Normal rendering without any CSG operations does give the expected result. void march(const vec2& cmin, //min x and y for the grid cell const vec2& cmax, //max x and y for the grid cell std::vector<vec2>& tri, float iso, float (*cmp1)(const vec2&), //distance from stationary circle float (*cmp2)(const vec2&) //distance from moving circle ) { unsigned int squareindex = 0; float scalar[4]; vec2 verts[8]; /* initial setup of the grid cell */ verts[0] = vec2(cmax.x, cmax.y); verts[2] = vec2(cmin.x, cmax.y); verts[4] = vec2(cmin.x, cmin.y); verts[6] = vec2(cmax.x, cmin.y); float s1,s2; /********************************** ********For-loop of interest****** *******Set difference between **** *******two implicit surfaces****** **********************************/ for(int i=0,j=0; i<4; ++i, j+=2){ s1 = cmp1(verts[j]); s2 = cmp2(verts[j]); if((s1 < iso)){ //if inside circle1 if((s2 < iso)){ //if inside circle2 scalar[i] = s2; //then set the scalar to the moving circle } else { scalar[i] = s1; //only inside circle1 squareindex |= (1<<i); //mark as inside } } else { scalar[i] = s1; //inside neither circle } } if(squareindex == 0) return; /* Usual interpolation between edge points to compute the new intersection points */ verts[1] = mix(iso, verts[0], verts[2], scalar[0], scalar[1]); verts[3] = mix(iso, verts[2], verts[4], scalar[1], scalar[2]); verts[5] = mix(iso, verts[4], verts[6], scalar[2], scalar[3]); verts[7] = mix(iso, verts[6], verts[0], scalar[3], scalar[0]); for(int i=0; i<10; ++i){ //10 = maxmimum 3 triangles, + one end token int index = triTable[squareindex][i]; //look up our indices for triangulation if(index == -1) break; tri.push_back(verts[index]); } } This gives me weird jaggies: It looks like the CSG operation is done without interpolation. It just "discards" the whole triangle. Do I need to interpolate in some other way, or combine the vertex scalar values? I'd love some help with this. A full testcase can be downloaded HERE EDIT: Basically, my implementation of marching squares works fine. It is my scalar field which is broken, and I wonder what the correct way would look like. Preferably I'm looking for a general approach to implement the three set operations I discussed above, for the usual primitives (circle, rectangle/square, plane)

  • Trying to draw a Rectangle to a Custom Container in Flex4/AS3

    - by Parris
    So below is the code I have so far. For now I simply want to make it draw a square and have it show up. Right now when I click the area defined in MXML as <components:PaintArea width="100%" height="100%" id="paint-a"></PaintArea> it shows nothing; however, the actionlistener is getting triggered and an element is being added to the group. Not sure exactly what is going on... perhaps for some reason it doesn't think the element is drawable? Anyways thanks for the help! public class PaintArea extends SkinnableContainer { private var canvas:Group; public function PaintArea() { super(); canvas = new Group(); canvas.clipAndEnableScrolling = true; canvas.percentHeight = 100; canvas.percentWidth = 100; canvas.addEventListener(MouseEvent.MOUSE_UP,drawRectangle); this.addElement(canvas); } private function drawRectangle(e:MouseEvent):void{ var r:Rect = new Rect(); r.fill = new SolidColor(0x00ff00,.5); canvas.addElement(r); } }

  • OAuth + Twitter on Android: Callback fails

    - by Samuh
    My Android application uses Java OAuth library, found here for authorization on Twitter. I am able to get a request token, authorize the token and get an acknowlegement but when the browser tries the call back url to reconnect with my application, it does not use the URL I provide in code, but uses the one I supplied while registering with Twitter. Note: 1. When registering my application with twitter, I provided a hypothetical call back url:http://abz.xyc.com and set the application type as browser. 2. I provided a callback url in my code "myapp" and have added an intent filter for my activity with Browsable category and data scheme as "myapp". 3. URL called when authorizing does contain te callback url, I specified in code. Any idea what I am doing wrong here? Relevant Code: public class FirstActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); OAuthAccessor client = defaultClient(); Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(client.consumer.serviceProvider.userAuthorizationURL + "?oauth_token=" + client.requestToken + "&oauth_callback=" + client.consumer.callbackURL)); startActivity(i); } OAuthServiceProvider defaultProvider() { return new OAuthServiceProvider(GeneralRuntimeConstants.request_token_URL, GeneralRuntimeConstants.authorize_url, GeneralRuntimeConstants.access_token_url); } OAuthAccessor defaultClient() { String callbackUrl = "myapp:///"; OAuthServiceProvider provider = defaultProvider(); OAuthConsumer consumer = new OAuthConsumer(callbackUrl, GeneralRuntimeConstants.consumer_key, GeneralRuntimeConstants.consumer_secret, provider); OAuthAccessor accessor = new OAuthAccessor(consumer); OAuthClient client = new OAuthClient(new HttpClient4()); try { client.getRequestToken(accessor); } catch (Exception e) { e.printStackTrace(); } return accessor; } @Override protected void onResume() { // TODO Auto-generated method stub super.onResume(); Uri uri = this.getIntent().getData(); if (uri != null) { String access_token = uri.getQueryParameter("oauth_token"); } } } // Manifest file <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".FirstActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="myapp"/> </intent-filter> </activity> </application>

  • Sub Rectangle or ROI problem in opencv

    - by iva123
    Hi, I'm trying to convert this c code(http://nashruddin.com/OpenCV_Eye_Detection) to the python code, but in c style, he used cvROI thing, since ROI functions are not supported by python-opencv, I tried cvGetSubRect so Here is the eye detection part of the code : eye_region = cvGetSubRect(image,cvRect(face.x,int(face.y + (face.height/4)),face.width,int(face.height/2))) eyes = cvHaarDetectObjects(eye_region,eyeCascade,memo,1.15,3,0,cvSize(25,15)) for e in eyes: cvRectangle(image, cvPoint( int(e.x), int(e.y)), cvPoint(int(e.x + e.width), int(e.y + e.height)), CV_RGB(0, 255, 0), 1, 8, 0) return image; When I run this code, It draws rectangles irrelevant places. I thought, eye_region coordinates are wrong, and tried some coordinates, but it didn't work. Any idea ? Note :Face detection method works very well, and it's code is same with the eye detection method.

  • Richfaces calendar manual input value not binding

    - by John
    Hi, I've got a richfaces calendar component defined as <rich:calendar id="startDate" value="#{myBean.dateSet.startDate}" timeZone="#{myBean.dateSet.timeZone}" datePattern="#{myBean.dateSet.datePattern}" enableManualInput="true" immediate="true"> <a4j:support event="onchanged" action="#{myBean.adjustEndDate}" reRender="startDate,endDate" ajaxSingle="true" /> </rich:calendar> when I'm changing the date using the calendar popup/gui everything is working fine. However when I'm changing it via the input text field, the value is not being updated to myBean.dateSet.startDate, although it is being updated correctly on the calendar component itself (i.e. if I click the icon for calendar popup it shows the updated current date). Any suggestions on how I can get it to update the value to myBean correctly? Thanks!

  • VS 2010 Coded UI Test - Launch Referenced Application

    - by Cory
    I'm using Visuial Studio's Coded UI Tests to run Automated UI tests on a WPF Application everytime a build runs on my TFS server. The problem I am running into is dynamically launching the executable based on the path where it was just built to, including the configuration(x86, x64). Is there any way to get the path to an executable in a referenced project so that I can launch the application dynamically from my test project?

  • How to save image to iphone's AddressBook using SDK API ?

    - by apple.dev
    My purpose is to process one image from image library, and save this image directly to one person record (i,e, "Tom" ), which is selected from AddressBook, I can see the new image replace Tom's previous image, but I can not save it to AddressBook. I implemented delegate ABPeoplePickerNavigationControllerDelegate, and using following logics, but whatever I tried, modified records can not be saved to address books. Any clues or suggest ? Thanks ABAddressBookRef addressBook= ABAddressBookCreate(); CFErrorRef error = NULL; BOOL wantToSaveChanges = YES; ABRecordSetValue(person, kABPersonFirstNameProperty, @"Shi", &error);//, &error) NSData * dataRef = UIImagePNGRepresentation(cellImage); ABPersonSetImageData(person, dataRef, &error); if (ABAddressBookHasUnsavedChanges(addressBook)) {\ NSLog(@"need to save "); if (wantToSaveChanges) { ABAddressBookSave(addressBook, &error); } else { ABAddressBookRevert(addressBook); } }else { NSLog(@"no changes"); } if (error != NULL) {/*...

  • How to debug manifest errors?

    - by Rryk
    I am creating an application that depends on third-party library, which in turn depends on MSVCP90D.dll (it was compiled with debug symbols). While starting the application it fails to start and provides an error message: I have found such library in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\redist\Debug_NonRedist\amd64\Microsoft.VC90.DebugCRT and C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\redist\Debug_NonRedist\x86\Microsoft.VC90.DebugCRT. As you can see one of them is 64-bit, while the other is 32-bit. When I have placed 32-bit into the directory of the application the application silently crashes while loading (log from Visual Studio Output window is below). With the 32-bit one I get another error message: If I press Abort -- programs shuts down, Retry results in breaking into debug session for crt0msg.c file. This is system file and I have no idea how to debug it. If I press Ignore I get yet another error message: So the question is how to debug such errors? Please give me some links where I can read more about it or point me out what exactly I should do in such cases. I know this relates to manifest problems -- please give me a good resource where I can read about resources, since what I have found have confused me even more.

  • OData and custom WCF WebGet methods

    - by reinier
    I've created an OData endpoint (using entity framework, WCF data service) and added a custom test WebGet test method like so: [WebGet(UriTemplate = "{text}")] public IQueryable<string> SplitString(string text) { if (text == null) throw new DataServiceException("text not specified"); var result = (from s in text.Split('-') orderby s select s); return result.AsQueryable(); } and a config line: config.SetServiceOperationAccessRule("SplitString", ServiceOperationRights.All); However, no matter how I specify the url, I can not get the text param to be filled out. (it is always null). so: http://localhost/myservice.svc/SplitString/testtext does not work. What is the correct url format (or UriTemplate) one should use? The only examples I found of odata and WebGet only have an example method which doesn't have any parameters.

  • Heroku and Github integration (how to structure the project)

    - by Noah
    I'm creating a webservice and I want to store the source on github and run the app on heroku. I haven't seen my exact scenario addressed anywhere on the 'net so far, so I'll ask it here: I want to have the following directory structure: /project .git README <-- project readme file TODO.otl <-- project outline ... <-- other project-related stuff /my_rails_app app config ... README <-- rails' readme file In the above, project corresponds to http://github.com/myuser/project, and my_rails_app is the code that should be pushed to heroku. Do I need a separate branch for the rails app, or is there a simpler way that I'm missing? I guess my project-related non-rails files could live in my_rails_app, but the rails README already lives there and it seems inconsistent to overwrite that. However, if I leave it, my github page for the rails app will contain the rails readme, which makes no sense. Thanks, Noah P.S. I tried just setting it up as described above and running git push heroku from the main project folder. Of course, heroku doesn't know I want to deploy the subfolder: -----> Heroku receiving push ! Heroku push rejected, no Rails or Rack app detected.

  • Conversion of bytes into a type without changing the application (ie storing the conversion method i

    - by geoaxis
    Is there a way to store a conversion strategy (for converting some bytes) into a database and then execute it on the run time. If one were to store a complete java file, you would need to compile it, store the class and some how inject into the already running system. I am not sure how this would be possible. But using some kind of dynamic language on JVM would be nice. I see an example of execution of groovy from within spring context here http://www.devx.com/tips/Tip/42789 but this is still static in nature as application context contains the reference to the implementation and cannot be changed by database. Perhaps with JavaConfig of context it is possible. I am exploring options now, specifically with Spring 3.0. Your suggestions in any direction would be welcome.

    I am trying to create a virtual directory and set it's permissions using IIS7 and C#. Here is a sample of my code: using (ServerManager serverManager = new ServerManager(webSite)) { ConfigurationSection anonymousAuthenticationSection = config.GetSection( @"system.webServer/security/authentication/anonymousAuthentication", webSite); anonymousAuthenticationSection["enabled"] = true; serverManager.CommitChanges(); return "true"; } This throws an exception and the message is: Cannot read configuration file due to insufficient permissions. Can someone help?

  • asp.net mvc compress stream and remove whitespace

    - by Bigfellahull
    Hi, So I am compressing my output stream via an action filter: var response = filterContext.HttpContext.Response; response.Filter = new DeflateStream(response.Filter), CompressionMode.Compress); Which works great. Now, I would also like to remove the excess whitespace present. I found Mads Kristensen's http module http://madskristensen.net/post/A-whitespace-removal-HTTP-module-for-ASPNET-20.aspx. I added the WhitespaceFilter class and added a new filter like the compression: var response = filterContext.HttpContext.Response; response.Filter = new WhitepaperFilter(response.Filter); This also works great. However, I seem to be having problems combining the two! I tried: var response = filterContext.HttpContext.Response; response.Filter = new DeflateStream(new WhitespaceFilter(response.Filter), CompressionMode.Compress); However this results in some major issues. The html gets completely messed up and sometimes I get an 330 error. It seems that the Whitespace filter write method gets called multiple times. The first time the html string is fine, but on subsequent calls its just random characters. I thought it might be because the stream had been deflated, but isnt the whitespace filter using the untouched stream and then passing the resulting stream to the DeflateStream call? Any ideas?
