  • Template can not be resolved to a type

    - by chaoticca
    I have this code in an android project, which I am working on, where SomeService refers to SomeService.template. Intent intent = new Intent(getApplicationContext(), SomeService.class); bindService(intent, conn, 0); when I run my code, however, I become this error: "SomeService can not be resolved to a type. - Java Problem" This code was not written by me. I need it for farther use, but I can not even test, if it does, what it's supposed to be doing. Where should I look for an error?

  • Why System.String's beahaves like a value type?

    - by Sorush Rabiee
    I want to write a 'Date' class that behaves like a Value Type. for example, Instead of writing a Clone method for setting properties safely, make the Date class to pass by value: public Date Birthday { get { return this.birthday; } set { this.birthday = value.Clone(); } //I want to write this.birthday = value; //without changing external value when this.Birthday changes } I know this is possible because System.String is a class and behaves like a value. for example: String s1 = "Hello"; String s2 = "Hi"; s1 = s2; s2="Hello"; Console.WriteLine(s1); //Prints 'Hi' First I thought writers of this class override '=' operator, but now I know that the '=' operator can not be overridden. so how they write String class?

  • Redis suggesstion for selecting data type

    - by PHP Connect
    We have questions based where in home page we were showing 2 list Questions by date modified Question have bigger views and ans count. And in this both listing if question have same views or ans count then sorting is based on date. Previously i am directly quiring to MySQL database and fetching the values so it's easy. But each page request hitting to MySQL it's bit expensive then start doing caching. I started using Redis. Following is the cases when i use redis cache Issues is On second listing i have to display questions by votes and not answered combine. How can i stored this type of data in redis to load faster with sorting based by 2 conditions votes with time and ans count with time?

  • MVCContrib ActionFilter PassParametersDuringRedirect still passes reference type in querystring

    - by redsquare
    I am attempting to use the PRG pattern in an asp.net mvc 2 rc application. I found that the MVCContrib project has a custom action filter that will auto persist the parameters in TempData In an action I have the following return this.RedirectToAction(c => c.Requested(accountAnalysis)); however this is adding a querystring param to the request e.g http://mysite.com/account/add?model=MyProject.Models.AccountAnalysisViewModel Can anyone explain how I can use the PassParametersDuringRedirect filter attribute from MVCContrib to not pass the ViewModel type in the querystring. I see a patch was issued to fix this however in the latest MvcContrib that supports MVC 2 RC it is commented out as follows public static RedirectToRouteResult RedirectToAction<T>(this Controller controller, Expression<Action<T>> action) where T : Controller { /*var body = action.Body as MethodCallExpression; AddParameterValuesFromExpressionToTempData(controller, body); var routeValues = Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(action); RemoveReferenceTypesFromRouteValues(routeValues); return new RedirectToRouteResult(routeValues);*/ return new RedirectToRouteResult<T>(action); } Any help much appreciated. Thanks

    I am trying to export pdf file using aspx and c#. I got the following error. Cannot implicitly convert type 'System.Collections.Generic.List'' to 'iTextSharp.text.Element' I have the following code using iTextSharp.text; using iTextSharp.text.pdf; using iTextSharp.text.html.simpleparser; StringBuilder strB = new StringBuilder(); document.Open(); if (text.Length.Equals(0))//export the text { GridView1.DataBind(); using (StringWriter sWriter = new StringWriter(strB)) { using (HtmlTextWriter htWriter = new HtmlTextWriter(sWriter)) { GridView1.RenderControl(htWriter); } } } else //export the grid { strB.Append(text); } using (TextReader sReader = new StringReader(strB.ToString())) { StyleSheet styles = new StyleSheet(); List<Element> list = new List<Element>(); list = HTMLWorker.ParseToList(sReader, styles); foreach (IElement elm in list) { document.Add(elm); } } I got the error in this line: list = HTMLWorker.ParseToList(sReader, styles); It's the first time that I am trying to export pdf files.

  • "Parameter type conflict" when calling Java Stored Procedure within another Java Stored Procedure

    - by GuiPereira
    Here's the problem (sorry for the bad english): i'm working with JDeveloper and Oracle10g, and i have a Java Stored Procedure that is calling another JSP like the code: int sd = 0; try { CallableStatement clstAddRel = conn.prepareCall(" {call FC_RJS_INCLUIR_RELACAO_PRODCAT(?,?)} "); clstAddRel.registerOutParameter(1, Types.INTEGER); clstAddRel.setString(1, Integer.toString(id_produto_interno)); clstAddRel.setString(2, ac[i].toString()); clstAddRel.execute(); sd = clstAddRel.getInt(1); } catch(SQLException e) { String sqlTeste3 = "insert into ateste values (SQ_ATESTE.nextval, ?)"; PreparedStatement pstTeste3 = conn.prepareStatement(sqlTeste3); pstTeste3.setString(1,"erro: "+e.getMessage()+ ac[i]); pstTeste3.execute(); pstTeste3.close(); } I'm recording the error in a table called ATESTE because this JavaSP is a procedure and not a function, I've to manipulate DML inside. So, the error message I'm getting is: 'parameter type conflict'... the function "FC_RJS_INCLUIR_RELACAO_PRODCAT" it's a Java Stored Procedure too, it's already exported to Oracle, and returns an int variable, and i have to read this to decide which webservice i will call from this JavaSP. I have already tried the OracleTyep.NUMBER in the registerOutParameter. Anyone knows what i'm doing wrong?

  • VB .NET DirectCast and Type Reflection

    - by msarchet
    The application that I am working on has a generic Parent Form called RSChild, that is used to perform some operations depending on whether or not the control that is contained within it is in a MdiTabManager or inside of its own modal form. Then the actual User Controls contained within Inherit from a Interface Called ObjectEdit (Objects that we allow to be edited). At a point in my code I am doing this. Public Function doesTabExist(ByVal id As Integer, ByVal recordType As Enums.eRecordType) As Boolean Dim alikePages As Object = (From tabs In DirectCast(Control.FromHandle(MainForm.SharedHandle), MainForm).XtraTabbedMdiManager1.Pages Where DirectCast(tabs.MdiChild, RSChild).RSObject.RecordType = recordType Select tabs) For Each page As DevExpress.XtraTabbedMdi.XtraMdiTabPage In alikePages Select Case recordType Case Enums.eRecordType.Doctor If id = DirectCast(castTabPageToRSChild(page).RSObject, UI.Doctor).ID Then pageToActive(page) Return True End If 'rest of the cases so the case block is repeated 10 times' End Function And my castTabPageToRSChild(page) is a lambda function as Such Dim castTabPageToRSChild As Func(Of DevExpress.XtraTabbedMdi.XtraMdiTabPage, RSChild) = Function(page) DirectCast(page.MdiChild, RSChild) So my Question is, I have about 10 case statements, all because I can't seem to find a way to use reflection to get the underlying Type of the RSObject Object. So I have the whole If block repeated over and over. I tried doing castTabPageToRSChild(page)RSObject.GetType and using that in the DirectCast and I also tried creating another object that was separate from that and doing the same thing. My code works as intended I'm just trying to see if there is a manner in which I didn't have a lot of replicated code. My vision would be to do something like For Each page As XtraMdiTabPage In alikePages If id = DirectCast(castTabPageToRSchild(page).RSObject, TypeOfThatObject).Id Then Return True Next However I have a feeling this is not possible due to the behavior of DirectCast.

  • Could not load type from assembly error

    - by George Mauer
    I have written the following simple test in trying to learn Castle Windsor's Fluent Interface: using NUnit.Framework; using Castle.Windsor; using System.Collections; using Castle.MicroKernel.Registration; namespace WindsorSample { public class MyComponent : IMyComponent { public MyComponent(int start_at) { this.Value = start_at; } public int Value { get; private set; } } public interface IMyComponent { int Value { get; } } [TestFixture] public class ConcreteImplFixture { [Test] public void ResolvingConcreteImplShouldInitialiseValue() { IWindsorContainer container = new WindsorContainer(); container.Register(Component.For<IMyComponent>().ImplementedBy<MyComponent>().Parameters(Parameter.ForKey("start_at").Eq("1"))); IMyComponent resolvedComp = container.Resolve<IMyComponent>(); Assert.AreEqual(resolvedComp.Value, 1); } } } When I execute the test through TestDriven.NET I get the following error: System.TypeLoadException : Could not load type 'Castle.MicroKernel.Registration.IRegistration' from assembly 'Castle.MicroKernel, Version=1.0.3.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc'. at WindsorSample.ConcreteImplFixture.ResolvingConcreteImplShouldInitialiseValue() When I execute the test through the NUnit GUI I get: WindsorSample.ConcreteImplFixture.ResolvingConcreteImplShouldInitialiseValue: System.IO.FileNotFoundException : Could not load file or assembly 'Castle.Windsor, Version=1.0.3.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc' or one of its dependencies. The system cannot find the file specified. If I open the Assembly that I am referencing in Reflector I can see its information is: Castle.MicroKernel, Version=1.0.3.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc and that it definitely contains Castle.MicroKernel.Registration.IRegistration What could be going on? I should mention that the binaries are taken from the latest build of Castle though I have never worked with nant so I didn't bother re-compiling from source and just took the files in the bin directory. I should also point out that my project compiles with no problem.

  • " not all code paths return a value" when return enum type

    - by netmajor
    I have enum list and method and i get error: " not all code paths return a value" Some idea whats wrong in my method ? I am sure I always return STANY type :/ Thanks for help :) private enum STANY { PATROL, CHAT, EAT, SEARCH, DIE }; private STANY giveState(int id, List<Ludek> gracze, List<int> plansza) { // Sprawdz czy gracz stoi na polu z jedzeniem i nie ma 2000 jednostek jedzenia bool onTheFood = false; onTheFood = CzyPoleZjedzeniem(id, gracze, plansza, onTheFood); if (onTheFood && (gracze[id].IloscJedzenia < startFood / 2)) return STANY.EAT; // Sprawdz czy gracz nie stoi na polu z innym graczem bool allKnowledge = true; allKnowledge = CzyPoleZInnymGraczem(id, gracze, allKnowledge); if (!allKnowledge) return STANY.CHAT; // Jesli ma ponad i rowna ilosc jedzenia patroluj if (gracze[id].IloscJedzenia >= startFood / 2) return STANY.PATROL; // Jesli ma mniej niz polowe jedzenia szukaj jedzenia if (gracze[id].IloscJedzenia > 0 && gracze[id].IloscJedzenia < startFood / 2) return STANY.SEARCH; // Jesli nie ma jedzenia umieraj if (gracze[id].IloscJedzenia <= 0) return STANY.DIE; }

  • input type file alternative and file upload best practice

    - by Ioxp
    Background: I am working on a file upload page that will extend an existing web portal. This page will allow for an end user to upload files from there local computer to our network (the files will not be stored on the web server, rather a remote workstation). The end user will have the ability to view the data that they have submitted by hyper-linking the files that have been uploaded on this page. Question 1: Is there an ASP.net alternative to the <input type="file" runat="server" /> HTML tag? The reason for asking is i would rather use an image button and display the file as an asp label on the portal to keep with a consistent style. Question 2: So i understand that giving the end user the ability to upload files to the server and then turn around to show them the data that they posted poses a security threat. So far i am using the id.PostedFile.ContentType and the file extension to reject the data if its not an accepted format (i.e. "text/plain", "application/pdf", "application/vnd.ms-excel", or "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"). Also the location where the files are uploaded to has a sufficient amount of virus and malware protection and this is not a concern. What, from the C# point of view, additional steps should i take to ensure that the end user cant take advantage and compromise the system in regards to allowing them to upload files?

  • LINQ-to-SQL: Could not find key member 'x' of key 'x' on type 'y'

    - by Austin Hyde
    I am trying to connect my application to a SQLite database with LINQ-to-SQL, and so far everything has worked fine. The only hitch was that the SQLite provider I am using does not support code generation (unless I was doing something wrong), so I manually coded the 4 tables in the DB. The solution builds properly, but will not run, giving me the error message Could not find key member 'ItemType_Id' of key 'ItemType_Id' on type 'Item'. The key may be wrong or the field or property on 'Item' has changed names. I have checked and double checked spellings and field names on the database and in the attribute mappings, but could not find any problems. The SQL for the table looks like this: CREATE TABLE [Items] ( [Id] integer PRIMARY KEY AUTOINCREMENT NOT NULL, [Name] text NOT NULL, [ItemType_Id] integer NOT NULL ); And my mapping code: [Table(Name="Items")] class Item { // [snip] [Column(Name = "Id", IsPrimaryKey=true, IsDbGenerated=true)] public int Id { get; set; } // [snip] [Column(Name="ItemType_Id")] public int ItemTypeId { get; set; } [Association(Storage = "_itemType", ThisKey = "ItemType_Id")] public ItemType ItemType { get { return _itemType.Entity; } set { _itemType.Entity = value; } } private EntityRef<ItemType> _itemType; // [snip] } This is really my first excursion into LINQ-to-SQL, and am learning as I go, but I cannot seem to get past this seeming simple problem. Why cannot LINQ see my association?

  • The Date type and the Android database

    - by cdonner
    I understand that SQLite stores dates as long integers. When I read rows into a cursor using the standard method (i.e. using the query() method that reads data into a cursor), the result is a date string that includes the time. If I want a different format, I have to parse the string back into a date - possible, but a bit backwards. By using a ViewBinder (as suggested in this question), I can pretty much do anything I want, but the date is already a string at the time the method executes. The accepted answer to the above question also suggests that storing dates as longs would help avoid this problem. I don't want to do that, just in case I want to interpret my data with something else than this application. Maybe I want to expose it via a provider. Is there a way to handle this in the database adapter instead, i.e. controlling the date format that the cursor contains, so that I don't have to change the schema, and don't have to parse the default output back into a Date type?

  • UITouch Event Propagation To Background UIViews

    - by drewww
    I'm having troubles getting any UIView that's not the foreground UIView to receive UITouch events. I'm building an all-Core Graphics-app, so I'm not using any built in UIViews or IB or anything - everything is programmatically constructed and drawn into. Here's my view hierarchy: Root View Type A Container Type A View Type A View Type A View Type B Container Type B View Type B View Type B View The containers are just vanilla UIView objects that I create programmatically and add instances of Type A and B to when they're created. I did this originally to make hitTesting easier—Type A objects can be drag-and-dropped onto Type B objects. Type A objects receive touch events fine, but Type B objects (which are contained by Type B Container which is behind Type A Container) don't receive touch events. Both containers occupy the entire screen; they're basically just convenience containers. If I pull Type B Container to the front (eg [self.view bringSubviewToFront:Type B Container]) it receives events properly, but then the Type A Container doesn't get events. How do I propagate events from the view that's on top? Both views occupy the entire screen, so it makes sense that the top-most view is catching the events, but how should I get it to pass those events on to Type B Container? I could inject some code in the container that passes the touch events back to the main ViewController which can pass them on to Type B Container but that feels really messy to me. Is there a nicer way to not have the Type A Container stop propagation? What's the best practice here?

  • Request for the permission of type 'System.Web.AspNetHostingPermission' failed when compiling web si

    - by ahsteele
    I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it I get the following compiler error: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines, I would change the machine's .NET Security Configuration trust level to full for the local intranet (fix outlined here). I believe this configuration utility relied upon the mscorcfg.msc which from some cursory research appears to be apart of the .NET 2.0 SDK. I have tried to follow the instructions from this Microsoft Support article running the command below to no avail.

  • MATLAB Builder NE (.NET Assembly) Data type question

    - by Brett
    Hi coders, I am using MATLAB Builder NE (MATLAB's integrated .NET assmebly builder), but I am having an issue with data types. I have compiled a small, very simple, function in matlab and build it for .NET. I am able to call the namespace and even the function just fine. However, my function returns a value, and MATLAB defaults to returning it as an "object[]" data type. However, I know that the value is an integer, but I can't figure out how to cast it. My MATLAB function looks like this: function addValue = Myfunction(value1, value2) addValue=value1+value2; end Pretty simple right? And then in .NET I can call it as: xClass.addValue (1, 3, 4); where xClass is the name of the MATLAB built class but when I try: int x = xClass.addValue (1, 3, 4); C# errors out. Typical .NET casting (int) doesn't work. The compiler states it cannot convert object[] to int. Does anyone have experience with the .NET builder in MATLAB that can help me with this? It is really throwing me for a loop. I have scanned through most of the MATLAB BUILDER doc (484 pages!) with zero help. Thank you, Brett

  • XML to Type - Quick way?

    - by MRFerocius
    Team; How are you doing? Im breaking my head trying to do this that seems simple but I can't figure it out... Suppose I have this XML as a string: <calles> <calle> <nombre>CALLAO AV.</nombre> <altura>1500</altura> <longitud>-58.3918617027</longitud> <latitud>-34.5916734896</latitud> <barrio>Recoleta</barrio> </calle> </calles> And and have this Type I created to map that XML: public class Ubicacion { public string Latitud { get; set; } public string Longitud { get; set; } public string Nombre { get; set; } public string Altura { get; set; } public string Barrio { get; set; } public Ubicacion() { } } I need to take that XML file and create an object with those values... Does somebody know a quick way to do it? with C#? I have been trying this but is not working at all... XElement dir = XElement.Parse(text); Ubicacion informacion = from d in dir.Elements("calle"). select new Ubicacion { Longitud = d.Element("longitud").Value, Latitud = d.Element("latitud").Value, Altura = d.Element("altura").Value, Nombre = d.Element("nombre").Value, Barrio = d.Element("barrio").Value, }; return informacion.Cast<Ubicacion>(); } Any ideas?

  • Double type returns -1.#IND/NaN error when calculating pi iteratively

    - by Draak
    I am working through a problem for my MCTS certification. The program has to calculate pi until the user presses a key, at which point the thread is aborted, the result returned to the main thread and printed in the console. Simple enough, right? This exercise is really meant to be about threading, but I'm running into another problem. The procedure that calculates pi returns -1.#IND. I've read some of the material on the web about this error, but I'm still not sure how to fix it. When I change double to Decimal type, I unsurprisingly get Overflow Exception very quickly. So, the question is how do I store the numbers correctly? Do I have to create a class to somehow store parts of the number when it gets too big to be contained in a Decimal? Class PiCalculator Dim a As Double = 1 Dim b As Double = 1 / Math.Sqrt(2) Dim t As Double = 1 / 4 Dim p As Double = 1 Dim pi As Double Dim callback As DelegateResult Sub New(ByVal _callback As DelegateResult) callback = _callback End Sub Sub Calculate() Try Do While True Dim a1 = (a + b) / 2 Dim b1 = Math.Sqrt(a * b) Dim t1 = t - p * (a - a1) ^ 2 Dim p1 = 2 * p a = a1 b = b1 t = t1 p = p1 pi = ((a + b) ^ 2) / (4 * t) Loop Catch ex As ThreadAbortException Finally callback(pi) End Try End Sub End Class

  • Correctly assigning value to a Core Data attribute with an integer data-type

    - by Gordon Fontenot
    I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --Edit 1-- Ok, so I can get rid of the warning by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber? --Edit 2-- Ok, so I'm realizing that there is some fundamental idea that I don't understand. I now understand that the 60 million + number can be cast back to the correct 0-5 number by using integerValue. So, it seems my question is how can I save an integer between 0-5 to the attribute if the NSNumber that is returned is over 60 million? Do I need to be using a different data type?

I write this function to get root of tree to be used in sameTree() function, to help comparison of "this" with given tree. Perhaps this is a OOP design issue... How should I restructure the above code that I do not get this warning and what is the concept I am missing here?

  • The ViewData item that has the key 'MY KEY' is of type 'System.String' but must be of type 'IEnumerable<SelectListItem>'.

    - by JBibbs
    I am trying to populate a dropdown list from a database mapped with Linq 2 SQL, using ASP.NET MVC 2, and keep getting this error. I am so confused because I am declaring a variable with the type IEnumerable<SelectListItem> on the second line, but the error makes me think this is not the case. I feel like this should be very simple, but I am struggling. Any help is appreciated. Here are the interesting bits of my controller: public ActionResult Create() { var db = new DB(); IEnumerable<SelectListItem> basetypes = db.Basetypes.Select(b => new SelectListItem { Value = b.basetype, Text = b.basetype }); ViewData["basetype"] = basetypes; return View(); } And here are the interesting bits of my view: <div class="editor-label"> <%: Html.LabelFor(model => model.basetype) %> </div> <div class="editor-field"> <%: Html.DropDownList("basetype") %> <%: Html.ValidationMessageFor(model => model.basetype) %> </div> Here is the Post action when submitting the Form // POST: /Meals/Create [HttpPost] public ActionResult Create(Meal meal) { if (ModelState.IsValid) { try { // TODO: Add insert logic here var db = new DB(); db.Meals.InsertOnSubmit(meal); db.SubmitChanges(); return RedirectToAction("Index"); } catch { return View(meal); } } else { return View(meal); } } Thanks.
