  • Sharepoint - Passing parameters in URL to NewForm.aspx

    - by kevin
    Any suggestions would be great. I've inherited a system and have been requested to add a context menu item to allow the ability to add a new item. I've set up the context menu with the new option and the newform.aspx to accept and pull parameters from the url for populating some fields. The context menu was created with the content editor web part and the follow JavaScript. function Custom_AddDocLibMenuItems(m, ctx) { var strAction = "window.location='http://address?para1=....'"; var strDisplayText = "Taxonomy"; var strImagePath = ""; // Add our new menu item CAMOpt(m, strDisplayText, strAction, strImagePath); // add a separator to the menu CAMSep(m); // false means that the standard menu items should also be rendered return false; } I'm having difficulties getting the proper values in order to concatenate them to the strAction string (which would be the full url of the newform.aspx. Any suggestions on how I retrieve the values of the columns for the item that the user right click to get context menu.

  • .NET Remoting Exception not handled Client-Side

    - by DanJo519
    I checked the rest of the remoting questions, and this specific case did not seem to be addressed. I have a .NET Remoting server/client set up. On the server side I have an object with a method that can throw an exception, and a client which will try to call that method. Server: public bool MyEquals(Guid myGuid, string a, string b) { if (CheckAuthentication(myGuid)) { logger.Debug("Request for \"" + a + "\".Equals(\"" + b + "\")"); return a.Equals(b); } else { throw new AuthenticationException(UserRegistryService.USER_NOT_REGISTERED_EXCEPTION_TEXT); } } Client: try { bool result = RemotedObject.MyEquals(myGuid, "cat", "dog"); } catch (Services.Exceptions.AuthenticationException e) { Console.WriteLine("You do not have permission to execute that action"); } When I call MyEquals with a Guid which causes CheckAuthentication to return false, .NET tries to throw the exception and says the AuthenticationException was unhandled. This happens server side. The exception is never marshaled over to the client-side, and I cannot figure out why. All of the questions I have looked at address the issue of an exception being handled client-side, but it isn't the custom exception but a base type. In my case, I can't even get any exception to cross the remoting boundary to the client. Here is a copy of AuthenticationException. It is in the shared library between both server and client. [Serializable] public class AuthenticationException : ApplicationException, ISerializable { public AuthenticationException(string message) : base(message) { } public AuthenticationException(SerializationInfo info, StreamingContext context) : base(info, context) { } #region ISerializable Members void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context) { base.GetObjectData(info, context); } #endregion }

  • ReflectionTypeLoadException with Silverlight serialization attributes

    - by RPS
    Hi all, I´m trying to inspect the types in a silverlight 4 assembly from a .NET 3.5 application. I have loaded the silverlight assembly with a Assembly.ReflectionOnlyLoadFrom sentence. contractsAssembly = Assembly.ReflectionOnlyLoadFrom(contractsAssemblyPath); When the .NET application tries to perform a call to GetTypes(), it throws a ReflectionTypeLoadException. Type[] types = contractsAssembly.GetTypes(); The LoaderExceptions property in the ReflectionTypeLoadException contains a list of exceptions, all of them regarding a problem loading a type that has serialization attributes. Type 'XXXX' in assembly 'YYYY' has method 'OnSerializing' with an incorrect signature for the serialization attribute that it is decorated with. The type XXXX has the following definitions in it: [System.Runtime.Serialization.OnSerializing] public void OnSerializing(System.Runtime.Serialization.StreamingContext context) [System.Runtime.Serialization.OnSerialized] public void OnSerialized(System.Runtime.Serialization.StreamingContext context) [System.Runtime.Serialization.OnDeserializing] public void OnDeserializing(System.Runtime.Serialization.StreamingContext context) [System.Runtime.Serialization.OnDeserialized] public void OnDeserialized(System.Runtime.Serialization.StreamingContext context) I have tried changing the method signature to internal or private, but with no luck. When I perform a GetTypes() call in a silverlight application that inspects this assembly I have no problems, so I thought that this was due to an incompatibility between .NET Framework and Silverlight. However, I see that .NET tools such as Reflector can inspect this Silverlight assembly, so there is a way to inspect Silverlight assemblies with serialization attributes from a .NET applciation. Could someone shed me some light on this? Many thanks in advance. Jose Antonio

  • Membership.GetUser() within TransactionScope throws TransactionPromotionException

    The following code throws a TransactionAbortedException with message "The transaction has aborted" and an inner TransactionPromotionException with message "Failure while attempting to promote transaction": using ( TransactionScope transactionScope = new TransactionScope() ) { try { using ( MyDataContext context = new MyDataContext() ) { Guid accountID = new Guid( Request.QueryString[ "aid" ] ); Account account = ( from a in context.Accounts where a.UniqueID.Equals( accountID ) select a ).SingleOrDefault(); IQueryable < My_Data_Access_Layer.Login > loginList = from l in context.Logins where l.AccountID == account.AccountID select l; foreach ( My_Data_Access_Layer.Login login in loginList ) { MembershipUser membershipUser = Membership.GetUser( login.UniqueID ); } [... lots of DeleteAllOnSubmit() calls] context.SubmitChanges(); transactionScope.Complete(); } } catch ( Exception E ) { [... reports the exception ...] } } The error occurs at the call to Membership.GetUser(). My Connection String is: <add name="MyConnectionString" connectionString="Data Source=localhost\SQLEXPRESS;Initial Catalog=MyDatabase;Integrated Security=True" providerName="System.Data.SqlClient" /> Everything I've read tells me that TransactionScope should just get magically applied to the Membership calls. The user exists (I'd expect a null return otherwise.)

  • entity framework POCO template in a n-tiers design question

    - by bryan
    HI all I was trying to follow the POCO Template walkthrough . And now I am having problems using it in n-tiers design. By following the article, I put my edmx model, and the template generated context.tt in my DAL project, and moved the generated model.tt entity classes to my Business Logic layer (BLL) project. By doing this, I could use those entities inside my BLL without referencing the DAL, I guess that is the idea of PI; without knowing anything about the data source. Now, I want to extend the entities (inside the model.tt) to perform some CUD action in the BLL project,so I added a new partial class same name as the one generated from template, public partial class Company { public static IEnumerable AllCompanies() { using(var context = new Entities()){ var q = from p in context.Companies select p; return q.ToList(); } } } however visual studio won't let me do that, and I think it was because the context.tt is in the DAL project, and the BLL project could not add a reference to the DAL project as DAL has already reference to the BLL. So I tried to added this class to the DAL and it compiled, but intelisense won't show up the BLL.Company.AllCompanies() in my web service method from my webservice project which has reference to my BLL project. What should I do now? I want to add CUD methods to the template generated entities in my BLL project, and call them in my web services from another project. I have been looking for this answer a few days already, and I really need some guides from here please. Bryan

  • TypeConverter prevents ApplyPropertyChanges in EntityFramework

    - by Felix
    I ran into an interesting problem (hopefully, interesting not just for me :) I am running Entity Framework 1 (.NET 3.5) and ASP.NET MVC 2. I have a Customer class that has many-to-one relationship with Country class (in other words, Country is a lookup table for customers - I described more in this post: http://stackoverflow.com/questions/2404801/explicit-casting-doesnt-work-in-default-model-binding ) I got TypeConverter to work; so I am getting a perfect object into controller's Post method. Create works fine; however, in Edit I am getting the following error when I call ApplyPropertyChanges: The existing object in the ObjectContext is in the Added state. Changes can only be applied when the existing object is in an unchanged or modified state. The controller code is fairly trivial: public ActionResult Edit(Customer customerToEdit) { if (ModelState.IsValid) { Customer cust = (Customer)context.GetObjectByKey( new EntityKey("BAEntities.Customers", "CustomerID", customerToEdit.CustomerID)); context.ApplyPropertyChanges(cust.EntityKey.EntitySetName, customerToEdit); context.SaveChanges(); } return View(...); } If I remove country from the form, it works fine; and if I assign dropdown value to EntityReference "manually" - it works as well. TypeConverter code is also fairly simple, but I've never used TypeConverter before, so I may be missing something here: public override object ConvertFrom(ITypeDescriptorContext typeContext, CultureInfo culture, object value) { if (value is string) { int countryID = Int16.Parse((string)value); Country country = (Country)context.GetObjectByKey( new EntityKey("BAEntities.Countries", "CountryID", countryID)); return country; } return base.ConvertFrom(typeContext, culture, value); }

  • Is it possible to create a custom, animated MKAnnotationView?

    - by smountcastle
    I'm trying to simulate the user location animation in MapKit (where-by the user's position is represented by a pulsating blue dot). I've created a custom subclass of MKAnnotationView and in the drawRect method I'm attempting to cycle through a set of colors. Here's a simpler implementation of what I'm doing: - (void)drawRect:(CGRect)rect { float magSquared = event.magnitude * event.magnitude; CGContextRef context = UIGraphicsGetCurrentContext(); if (idx == -1) { r[0] = 1.0; r[1] = 0.5; r[2] = 0; b[0] = 0; b[1] = 1.0; b[2] = 0.5; g[0] = 0.5; g[1] = 0; g[2] = 1.0; idx = 0; } // CGContextSetRGBFillColor(context, 1.0, 1.0 - magSquared * 0.015, 0.211, .6); CGContextSetRGBFillColor(context, r[idx], g[idx], b[idx], 0.75); CGContextFillEllipseInRect(context, rect); idx++; if (idx > 3) idx = 0; } Unfortunately this just causes the annotations to be one of the 3 different colors and doesn't cycle through them. Is there a way to force the MKAnnotations to continually redraw so that it appears to be animated?

  • Why is my Android app camera preview running out of memory on my AVD?

    - by Bryan
    I have yet to try this on an actual device, but expect similar results. Anyway, long story short, whenever I run my app on the emulator, it crashes due to an out of memory exception. My code really is essentially the same as the camera preview API demo from google, which runs perfectly fine. The only file in the app (that I created/use) is as below- package berbst.musicReader; import java.io.IOException; import android.app.Activity; import android.content.Context; import android.hardware.Camera; import android.os.Bundle; import android.view.SurfaceHolder; import android.view.SurfaceView; /********************************* * Music Reader v.0001 * Still VERY under construction. * @author Bryan * *********************************/ public class MusicReader extends Activity { private MainScreen main; @Override //Begin activity public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); main = new MainScreen(this); setContentView(main); } class MainScreen extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder sHolder; Camera cam; MainScreen(Context context) { super(context); //Set up SurfaceHolder sHolder = getHolder(); sHolder.addCallback(this); sHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceCreated(SurfaceHolder holder) { // Open the camera and start viewing cam = Camera.open(); try { cam.setPreviewDisplay(holder); } catch (IOException exception) { cam.release(); cam = null; } } public void surfaceDestroyed(SurfaceHolder holder) { // Kill all our crap with the surface cam.stopPreview(); cam.release(); cam = null; } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { // Modify parameters to match size.

  • Android - Views in Custom Compound Component are not inflated (findByView returns null)

    - by Julian Arz
    I have made a Custom Component in XML, consisting of a button with an imageview stacked on top of it: <myapp.widget.ClearableCaptionedButton xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <Button android:id="@+id/ccbutton_button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_vertical|left" android:textAppearance="?android:attr/textAppearanceMedium" android:background="@android:drawable/edit_text"/> <ImageView android:id="@+id/ccbutton_clear" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="5dip" android:layout_alignRight="@id/ccbutton_button" android:layout_alignTop="@id/ccbutton_button" android:layout_alignBottom="@id/ccbutton_button"/> </myapp.widget.ClearableCaptionedButton> extract of java source code: public class ClearableCaptionedButton extends RelativeLayout implements OnClickListener { ... public ClearableCaptionedButton(Context context, AttributeSet attrs) { super(context, attrs); // some stuff that works fine } .. protected void onFinishInflate() { super.onFinishInflate(); mButton = (Button) findViewById(R.id.ccbutton_button); mClear = (ImageView) findViewById(R.id.ccbutton_clear); mButton.setText(""); // error here: mButton == null } My problem is similar to this one. When i try to find the views inside the custom compound, findViewById returns null. But, as you can see, i already added super(context, attrs); to the constructor. i am using the custom component directly in xml layout, like this: <LinearLayout> <!-- some stuff --> <de.pockettaxi.widget.ClearableCaptionedButton android:layout_width="fill_parent" android:layout_height="wrap_content" app:caption="to"/> </LinearLayout> can anybody spot something? thanks.

  • Entity Framework lazy loading doesn't work from other thread

    - by Thomas Levesque
    Hi, I just found out that lazy loading in Entity Framework only works from the thread that created the ObjectContext. To illustrate the problem, I did a simple test, with a simple model containing just 2 entities : Person and Address. Here's the code : private static void TestSingleThread() { using (var context = new TestDBContext()) { foreach (var p in context.Person) { Console.WriteLine("{0} lives in {1}.", p.Name, p.Address.City); } } } private static void TestMultiThread() { using (var context = new TestDBContext()) { foreach (var p in context.Person) { Person p2 = p; // to avoid capturing the loop variable ThreadPool.QueueUserWorkItem( arg => { Console.WriteLine("{0} lives in {1}.", p2.Name, p2.Address.City); }); } } } The TestSingleThread method works fine, the Address property is lazily loaded. But in TestMultiThread, I get a NullReferenceException on p2.Address.City, because p2.Address is null. It that a bug ? Is this the way it's supposed to work ? If so, is there any documentation mentioning it ? I couldn't find anything on the subject on MSDN or Google... And more importantly, is there a workaround ? (other than explicitly calling LoadProperty from the worker thread...) Any help would be very appreciated PS: I'm using VS2010, so it's EF 4.0. I don't know if it was the same in the previous version of EF...

  • How to use Castle Windsor with ASP.Net web forms?

    - by Xian
    I am trying to wire up dependency injection with Windsor to standard asp.net web forms. I think I have achieved this using a HttpModule and a CustomAttribute (code shown below), although the solution seems a little clunky and was wondering if there is a better supported solution out of the box with Windsor? There are several files all shown together here // index.aspx.cs public partial class IndexPage : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Logger.Write("page loading"); } [Inject] public ILogger Logger { get; set; } } // WindsorHttpModule.cs public class WindsorHttpModule : IHttpModule { private HttpApplication _application; private IoCProvider _iocProvider; public void Init(HttpApplication context) { _application = context; _iocProvider = context as IoCProvider; if(_iocProvider == null) { throw new InvalidOperationException("Application must implement IoCProvider"); } _application.PreRequestHandlerExecute += InitiateWindsor; } private void InitiateWindsor(object sender, System.EventArgs e) { Page currentPage = _application.Context.CurrentHandler as Page; if(currentPage != null) { InjectPropertiesOn(currentPage); currentPage.InitComplete += delegate { InjectUserControls(currentPage); }; } } private void InjectUserControls(Control parent) { if(parent.Controls != null) { foreach (Control control in parent.Controls) { if(control is UserControl) { InjectPropertiesOn(control); } InjectUserControls(control); } } } private void InjectPropertiesOn(object currentPage) { PropertyInfo[] properties = currentPage.GetType().GetProperties(); foreach(PropertyInfo property in properties) { object[] attributes = property.GetCustomAttributes(typeof (InjectAttribute), false); if(attributes != null && attributes.Length > 0) { object valueToInject = _iocProvider.Container.Resolve(property.PropertyType); property.SetValue(currentPage, valueToInject, null); } } } } // Global.asax.cs public class Global : System.Web.HttpApplication, IoCProvider { private IWindsorContainer _container; public override void Init() { base.Init(); InitializeIoC(); } private void InitializeIoC() { _container = new WindsorContainer(); _container.AddComponent<ILogger, Logger>(); } public IWindsorContainer Container { get { return _container; } } } public interface IoCProvider { IWindsorContainer Container { get; } }

  • Doubts About Core Data NSManagedObject Deep Copy

    - by Jigzat
    Hello everyone, I have a situation where I must copy one NSManagedObject from the main context into an editing context. It sounds unnecessary to most people as I have seen in similar situations described in Stackoverflow but I looks like I need it. In my app there are many views in a tab bar and every view handles different information that is related to the other views. I think I need multiple MOCs since the user may jump from tab to tab and leave unsaved changes in some tab but maybe it saves data in some other tab/view so if that happens the changes in the rest of the views are saved without user consent and in the worst case scenario makes the app crash. For adding new information I got away by using an adding MOC and then merging changes in both MOCs but for editing is not that easy. I saw a similar situation here in Stackoverflow but the app crashes since my data model doesn't seem to use NSMutableSet for the relationships (I don't think I have a many-to-many relationship, just one-to-many) I think it can be modified so I can retrieve the relationships as if they were attributes for (NSString *attr in relationships) { [cloned setValue:[source valueForKey:attr] forKey:attr]; } but I don't know how to merge the changes of the cloned and original objects. I think I could just delete the object from the main context, then merge both contexts and save changes in the main context but I don't know if is the right way to do it. I'm also concerned about database integrity since I'm not sure that the inverse relationships will keep the same reference to the cloned object as if it were the original one. Can some one please enlighten me about this?

  • IHttpAsyncHandler and IObservable web requests

    - by McLovin
    Within Async handler I'm creating an IObservable from webrequest which returns a redirect string. I'm subscribing to that observable and calling AsyncResult.CompleteCall() but I'm forced to use Thread.Sleep(100) in order to get it executed. And it doesn't work every time. I'm pretty sure this is not correct. Could you please shine some light.

  • How can I get the correct DisplayMetrics from an AppWidget in Android?

    - by Gary
    I need to determine the screen density at runtime in an Android AppWidget. I've set up an HDPI emulator device (avd). If set up a regular executable project, and insert this code into the onCreate method: DisplayMetrics dm = getResources().getDisplayMetrics(); Log.d("MyTag", "screen density " + dm.densityDpi); This outputs "screen density 240" as expected. However, if I set up an AppWidget project, and insert this code into the onUpdate method: DisplayMetrics dm = context.getResources().getDisplayMetrics(); Log.d("MyTag", "screen density " + dm.densityDpi); This outputs "screen density 160". I noticed, hooking up the debugger, that the mDefaultDisplay member of the Resources object here is null in the AppWidget case. Similarly, if I get a resource at runtime using the Resources object obtained from context.getResources() in the AppWidget, it returns the wrong resource based on screen density. For instance, I have a 60x60px drawable for mdpi, and an 80x80 drawable for hdpi. If I get this Drawable object using context.getResources().getDrawable(...), it returns the 60x60 version. Is there any way to correctly deal with resources at runtime from the context of an AppWidget? Thanks!

  • Problem with MessageContract, Generic return types and clientside naming

    - by Soeteman
    I'm building a web service which uses MessageContracts, because I want to add custom fields to my SOAP header. In a previous topic, I learned that a composite response has to be wrapped. For this purpose, I devised a generic ResponseWrapper class. [MessageContract(WrapperNamespace = "http://mynamespace.com", WrapperName="WrapperOf{0}")] public class ResponseWrapper<T> { [MessageBodyMember(Namespace = "http://mynamespace.com")] public T Response { get; set; } } I made a ServiceResult base class, defined as follows: [MessageContract(WrapperNamespace = "http://mynamespace.com")] public class ServiceResult { [MessageBodyMember] public bool Status { get; set; } [MessageBodyMember] public string Message { get; set; } [MessageBodyMember] public string Description { get; set; } } To be able to include the request context in the response, I use a derived class of ServiceResult, which uses generics: [MessageContract(WrapperNamespace = "http://mynamespace.com", WrapperName = "ServiceResultOf{0}")] public class ServiceResult<TRequest> : ServiceResult { [MessageBodyMember] public TRequest Request { get; set; } } This is used in the following way [OperationContract()] ResponseWrapper<ServiceResult<HCCertificateRequest>> OrderHealthCertificate(RequestContext<HCCertificateRequest> context); I expected my client code to be generated as ServiceResultOfHCCertificateRequest OrderHealthCertificate(RequestContextOfHCCertificateRequest context); Instead, I get the following: ServiceResultOfHCCertificateRequestzSOTD_SSj OrderHealthCertificate(CompType1 c1, CompType2 c2, HCCertificateRequest context); CompType1 and CompType2 are properties of the RequestContext class. The problem is that a hash is added to the end of ServiceResultOfHCCertificateRequestzSOTD_SSj. How do I need define my generic return types in order for the client type to be generated as expected (without the hash)?

  • Is there any way to access files in your source tree in Android?

    - by Chris Thompson
    Hi all, This is a bit unorthodox but I'm trying to figure out if there's a way to access files stored in the src tree of my applications apk in Android. I'm trying to use i-Jetty (Jetty implementation for Android) and rather than use it as a separate application and manually download my war file, I'd rather just bake i-jetty in. However, in order to use (easily) standard html/jsp I need to be able to give it a document root, preferably within my application's apk file. I know Android specifically works to prevent you from accessing (freely) the stuff on the actual system so this may not be possible, but I'm thinking it might be possible to access something within the apk. One option to work around this would be to have all of the files stored in the res directory and then copy them to the sdcard on startup but this wouldn't allow me to automatically remove the files on uninstall. To give you an idea of what I've tried, currently, the html files are stored in org.webtext.android Context rootContext = new Context(server_, "/", Context.SESSIONS); rootContext.setResourceBase("org/webtext/webapp"); Returns a 404 error. final URL url = this.getClassLoader().getResource("org/webtext/webapp"); Context html = new WebAppContext(url.toExternalForm(), "/"); Blows up with a NullPointerException because no URL is returned from the getResource call. Any thoughts would be greatly appreciated! Thanks, Chris

  • What is the best way to update an unattached entity on Entity Framework?

    - by Carlos Loth
    Hi, In my project I have some data classes to retrieve data from the database using the Entity Framework. We called these classes *EntityName*Manager. All of them have a method to retrieve entities from database and they behave most like this: static public EntityA SelectByName(String name) { using (var context = new ApplicationContext()) { var query = from a in context.EntityASet where a.Name == name select a; try { var entityA = query.First(); context.Detach(entityA); return entityA; } catch (InvalidOperationException ex) { throw new DataLayerException( String.Format("The entityA whose name is '{0}' was not found.", name), ex); } } } You can see that I detach the entity before return it to the method caller. So, my question is "what is the best way to create an update method on my *EntityA*Manager class?" I'd like to pass the modified entity as a parameter of the method. But I haven't figured out a way of doing it without going to the database and reload the entity and update its values inside a new context. Any ideas? Thanks in advance, Carlos Loth.

  • Android Custom Adapter with Bar Progress

    - by xger86x
    Hi, i have a custom adapter for an arraylist. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <ProgressBar android:id="@+id/downloadprogress" style="?android:attr/progressBarStyleHorizontal" android:layout_width="200dip" android:layout_height="wrap_content" android:max="100" android:progress="50" android:secondaryProgress="75" /> <TextView android:id="@+id/tripsname" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout> but when i try to access to the progress bar in the adapter private class MyAdapter extends ArrayAdapter<Trip> { int resource; public MyAdapter(Context context, int resource, ArrayList<Trip> items) { super(context, resource,items); this.resource=resource; } @Override public View getView(int position, View convertView, ViewGroup parent) { LinearLayout tripListItemView; final Trip t = getItem(position); String name = t.getName(); boolean offline = t.isOffline() ; if(convertView==null) { tripListItemView = new LinearLayout(getContext()); String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi; vi = (LayoutInflater)getContext().getSystemService(inflater); vi.inflate(resource, tripListItemView, true); } else { tripListItemView = (LinearLayout) convertView; } setProgressBarVisibility(true); View v = findViewById(R.id.downloadprogress); ProgressBar progressHorizontal = (ProgressBar) findViewById(R.id.downloadprogress); it always return null, like it doesn't find the progress bar. However, the progress bar is shown in the list, but i need to access to it inside the adapter. Anybody knows the solution? Thanks
