  • Error loading Variables stage.loaderInfo - AS3

    - by Dimitree
    I have a Document class that loads variables from Facebook with the use of stage.loaderInfo var connect:FacebookConnectObject = new FacebookConnectObject( facebook, API_KEY, this.stage.loaderInfo ); But when I change the Document class (with another one responsible for the layout of my app), and try call the above from a movieclip that exists in my application with the use: var facebook_class:FacebookAp = new FaceBppkApp addChild(facebook_class) I get error TypeError: Error #1009: Cannot access a property or method of a null object reference. I believe the error comes fro this line this.stage.loaderInfo since I changed the scope... How I am supposed to fix that?

  • NHibernate ManyToMany Relationship Cascading AllDeleteOrphan StackOverflowException

    - by Chris
    I have two objects that have a ManyToMany relationship with one another through a mapping table. Though, when I try to save it, I get a stack overflow exception. The following is the code for the mappings: //EventMapping.cs HasManyToMany(x => x.Performers).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("EventId").ChildKeyColumn("PerformerId"); //PerformerMapping.cs HasManyToMany<Event>(x => x.Events).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("PerformerId").ChildKeyColumn("EventId"); When I change the performermapping.cs to Cascade.None() I get rid of the exception but then my Event Object doesn't have the performer I associate with it. //In a unit test, paraphrased event.Performers.Add(performer); //Event eventRepository.Save<Event>(event); eventResult = eventRepository.GetById<Event>(event.id); //Event eventResult.Performers[0]; //is null, should have performer in it How should I be writing this properly? Thanks

  • iPhone OSStatus -25308 or errSecInteractionNotAllowed SFHFKeychainUtils

    - by George Octavio
    Hi again guys. I'm trying to access my iPhone's device keychain. I want to access in order to create a simple user-password value intended for a log in function. This is the code I'm using from SFHFKeychainUtils NSArray *keys = [[[NSArray alloc] initWithObjects: (NSString *) kSecClass, kSecAttrService, kSecAttrLabel, kSecAttrAccount, kSecValueData, nil] autorelease]; NSArray *objects = [[[NSArray alloc] initWithObjects: (NSString *) kSecClassGenericPassword, serviceName, serviceName, @"TestUser", @"TestPass", nil] autorelease]; NSDictionary *query = [[[NSDictionary alloc] initWithObjects: objects forKeys: keys] autorelease]; OSStatus status = SecItemAdd((CFDictionaryRef) query, NULL); } else if (status != noErr) { //Output to screen with error code goes here return NO; } return YES; } The error code I'm getting is OSStatus-25308 or errSecInteractionNotAllowed. I'm guessing this means I don't actually have access to my iPhone's keychain? Is there a way to allow access? Thanks for your time.

  • FlexNativeMenu Problem in Air Application

    - by glatour
    I am trying to add a flexnativemenu to my air application and I have some problems... When I set it in the windowApplication, I get null errors in child controls so I tried to set this.menu = myMainMenu (which is my flexnativemenu) in the creation complete event but the menu doesn't show up... I tried to show an alert message before setting the menu and the menu appeared in the application. Is there a method I can call to force the application to "redraw" itself in the creationComplete event??? Thanks!

  • ActionScript Clean Up

    - by TheDarkIn1978
    i want to deallocate a spriteClass from memory and remove it from the display list. when the spriteClass is instantiated, it creates some of it's own sprites with new tweens and tween events and add them as children. i understand that the tween events must be removed in order for the spritClass to become available for garbage collection, and only afterwards should i nullify the spriteClass, but should i also nullify and remove the spriteClass's sprite children and tweens as well, or does it not matter? essentially i'd like to know if by nullifying the spriteClass it automatically removes all of it's added children and new instantiations like tweens, sprites, rects, whatever, or am i responsible for removing them all and otherwise the spriteClass isn't truly null until i do so?

  • how subsonic SP should return a value

    - by android.sm
    Hi all, I'm very much new to SubSonic and need a little guidance. Here, I want to know how my SP should return a value. Currently, when I execute it I simply pass an Int and it returns me a string value. Here is code: SubSonic SP: public static StoredProcedure GetQuote(int? CategoryId) { StoredProcedure sp = new StoredProcedure("GetQuote", DataService.GetInstance("Quotes Provider"), "dbo"); sp.Command.AddParameter("@CategoryId", CategoryId, DbType.Int32, 0, 10); return sp; } My Code: public bool GetQuote(int category, out string quote) { bool val = false; quote = ""; try { StoredProcedure sp = SPs.GetQuote(category); if (sp != null) { sp.Execute(); val = true; } } catch (Exception err) { throw err; } return val; } Thanks all

  • c# HTTPListener encoding issue

    - by Rob Griffin
    I have a Java application sending HTTP requests to a C# application. The C# app uses HTTPListener to listen for requests and respond. On the Java side I'm encoding the URL using UTF-8. When I send a \ character it gets encoded as %5C as expected but on the C# side it becomes a / character. The encoding for the request object is Windows-1252 which I think may be causing the problem. How do I set the default encoding to UTF-8? Currently I'm doing this to convert the encoding: foreach (string key in request.QueryString.Keys) { if (key != null) { byte[] sourceBytes =request.ContentEncoding.GetBytes(request.QueryString[key]); string value = Encoding.UTF8.GetString(sourceBytes)); } } This handles the non ASCII characters I'm also sending but doesn't fix the slash problem. Examining request.QueryString[key] in the debugger shows that the / is already there.

  • Is POSTing a Dictionary to an .NET MVC action possible?

    - by Brenton Alker
    I have a form which contains a series of fields like: <input type="text" name="User[123]" value="Alice" /> <input type="text" name="User[456]" value="Bob" /> ... Where the index of the User array (123 and 456) are ID's associated with the value. I'm trying to update these values in the controller. My thinking is that a Dictionary that maps ID to name would work, but creating the action like: public void Save(Dictionary<string, string> user) { // ... } results in the user parameter being null. So, is passing a Dictionary possible? or, is there another method to achieve this?

  • Issue on passing a checkbox set to an AppEngine script through jQuery Ajax/Json

    - by Jorge
    I have a set of checkboxes with multiple choice allowed. I parse the set this way: if ($("input[name='route_day']:checked").length > 0) { $("input[name='route_day']:checked").each(function(){ if(this.value != null) route_days_hook.push(this.value); }); dataTrap.route_days = $.JSON.encode(route_days_hook); } ...and pull the whole dataTrap to an AppEngine Python script via jQuery ajax. However, the Python script just bugs. If i change dataTrap.route_days value to a string instead of the JSON encoded object, everything works fine. My question is: how can i pass a checkbox set to the script using Ajax and still be able to iterate over it on the script?

  • How to check for empty values on two fields then prompt user of error using javascript

    - by Matthew
    Hello guys, I hope I can explain this right I have two input fields that require a price to be entered into them in order for donation to go through and submit. The problem that I am having is that I would like the validation process check to see if one of the two fields has a value if so then proceed to submit. If both fields are empty then alert. This is what I have in place now: function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") {alert(alerttxt);return false;} else {return true} } } function validate_form(thisform) { with (thisform) { if (validate_required(input1,"Need a donation amount to continue")==false) {input1.focus();return false;} else if (validate_required(input2,"Need a donation amount to continue")==false) {input2.focus();return false;} } } I would like to ultimately like to get this over to Jquery as well Thanks guys any help would do Matt

  • error 2016: Condition cannot be specified for Column member

    - by IP
    I am having some issues with Entity Framework in VS2010 The problem I'm getting is described very well here... http://social.msdn.microsoft.com/Forums/en/adonetefx/thread/cacf6a76-09a8-4c90-9502-d8b87c2f6bea It's basically happening when a Foreign key is pointed at the primary key of another table...but if I take off the StoreGeneratedPattern as "Identity", then it tries to insert a value into the identity field ** EDIT So, what it seems to be is that EF4 can't handle a null relationship when the primary key is set to StoreGeneratedPattern="Identity". If I create a FK pointing to this primary key, and make it nullable (effectively creating a 0...M relationship), then it throws this compilation error. Removing StoreGeneratedPattern="Identity" fixes the issue, but causes issues elseware It works if the foreign key is set to not nullable

  • how to listen for changes in Contact Database

    - by hap497
    Hi, I am trying to listen for any change in the contact database. So I create my contentObserver which is a child class of ContentObserver: private class MyContentObserver extends ContentObserver { public MyContentObserver() { super(null); } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); System.out.println (" Calling onChange" ); } } MyContentObserver contentObserver = new MyContentObserver(); context.getContentResolver().registerContentObserver (People.CONTENT_URI, true, contentObserver); But When I use 'EditContactActivity' to change the contact database, My onChange function does not get called.

    - by John Smith

  • DataTable C# Empty column type

    - by Dested
    I am trying build a DataTable one row at a time using the following code. foreach (var e in Project.ProjectElements[hi.FakeName].Root.Elements()) { index = 0; object[] obj=new object[count]; foreach (var holdingColumn in names) { string d = e.Attribute(holdingColumn.Key).Value; obj[index++] = d; } dt.Rows.Add(obj); } The problem is the DataTable has types tied to the columns. Sometimes im passing null (or an empty string) in that object index and it is telling me that it cant be converted properly to a DateTime (in this case). My question is what should I default this value to, or is there some way to have the DataTable ignore empty values.

  • Javascript cross-domain web request fails with Status=0?

    - by Tav
    Yes, I know the following code does not work in IE. I know IE expects me to use XDomainRequest() instead. I don't care about that. This is firefox only. I'm trying to do a cross-domain web request in firefox javascript. I keep getting a status of 0. Does anyone know why? var url = "http://newyork.craigslist.org"; var xdr = new XMLHttpRequest(); //Yes, I know IE expects XDomainRequest. Don't care xdr.onreadystatechange = function() { if (xdr.readyState == 4) { alert(xdr.status); //Always returns 0! And xdr.responseText is blank too } } xdr.open("get", url, true); xdr.send(null); Shouldn't that work?

  • How to determine if an event is already subscribed

    - by Ram
    Hi, In my .NET application I am subscribing to events from another class. The subscription is conditional. I am subscribing to events when the control is visible and de-subscribing it when it become invisible. However in some conditions I do not want to de-subscribe the event even if the control is not visible as I want the result of an operation which is happening on background thread . Is there any way through which I can determine if a that class has already subscribed to that event. I know we can do it in the class which will raise that event by checking event with null but I don not know how to do it in a class which will subscribe to that event.

  • T-SQL out of order insert

    - by tearman
    Basically I have a User-Defined Table Type (for use as a table-valued variable) which I'm referencing in a stored procedure that effectively just calls two other stored procedures, then inserts those values into the table type. Id est INSERT INTO @tableValuedVariable (var1, var2, var3, var4, var5) EXEC [dbo].StoredProcedure1; INSERT INTO @tableValuedVariable (var1, var2, var5) EXEC [dbo].StoredProcedure2; You can probably already tell what I'm going to ask. Basically StoredProcedure2 only returns a few of the values the table is set to hold, and I'd like those other variables to just be null (as defined as default). Only SQL is complaining that I'm not specifying all the variables available to that table. The return datasets can be quite sizable so I'd like to avoid loops and such for obvious reasons. Thanks for any help.

  • How can I modify a custom object in an ASP.NET FormView based on a button click?

    - by David
    I have a FormView that modifies an instance of a custom class. The various form controls (TextBox, DropDownList etc.) are working fine. However, I want to include a Button that will modify the state of the DataItem based on some very simple logic. There is no form control which could control this change in a non-confusing way. So I tried adding a Button and modifying the state of the DataItem in the code-behind. But the problem I encounter is that the FormView's DataItem is null/nothing. From reading this SO question it seems the problem is that the item is not databound when the Button's Click event is fired. So, the question; Is it possible to get the DataItem for the FormView during a Button's Click event? and if not: what are my options for implementing this? Thanks in advance. Edit: I can include any code that might help

  • eclise java internal webbrowser progress listener?

    - by deepthinker121
    Hi All, I need to open an internal web browser from a custom eclipse wizard I have created - and so I am using IWebBrowser webBrowser = browser.createBrowser (IWorkbenchBrowserSupport.LOCATION_BAR | IWorkbenchBrowserSupport.AS_EDITOR | IWorkbenchBrowserSupport.NAVIGATION_BAR | IWorkbenchBrowserSupport.STATUS, null,"TestBrowser", "TestBrowser"); URL url = new URL("http://localhost:8080/app"); webBrowser.openURL(url); Now the problem is - the openURL needs time to complete as it tries to load a page for a webapp and as I am not able to get the progress of the 'load page' operation of the URL - my wizard progressmonitor completes before the URL can be completely loaded . Is there any way to get the status of the page load operation - (to check if its complete or it failed) or add a listener to indicate completion of page load? It is okay for me to use some other implementations of internal web browsers - so please suggest some other approach we cannot add a listener to IWebBrowser.. Thanks for ur help !!

  • How to get Resharper to show a Refactoring that it already has.

    - by AngryHacker
    Whenever Resharper encounters code like this: (treeListNode.Tag as GridLine).AdvertiserSeparation = 5; it presents you with a possible fix (since treeListNode.Tag as GridLine might be null). It says: 'Replace with Direct Cast', which turns the code into the following: ((GridLine) treeListNode.Tag).AdvertiserSeparation = 5; This is great. However, when it encounters code like this: GridLine line = treeListNode.Tag as GridLine; line.AdvertiserSeparation = 5; Resharper simply displays a warning 'Possible System.NullReferenceException', but does not offer me to 'Replace with Direct Cast'. Is there a way to make Resharper offer me this refactoring, since it already has it?

  • getnameinfo prototype asks for sockaddr not sockaddr_in ?

    The getnameinfo prototype asks for sockaddr but I have only seen examples using sockaddr_in.
