  • android app working on simulator but not on phone

    - by raqz
    i have this app that i developed and it works great on the simulator with no errors what so ever. but the moment i try to run the same on the phone for testing, the app crashes stating filenotfoundexception. it says the file /res/drawable/divider_horizontal.9.png is missing. but actually speaking, i have never referenced that file through my code. i believe its a system/os file that is unavailable. i have a custom list view, i guess its the divider there... could somebody please suggest what is wrong here. i believe this is a similar issue discussed here..but i am unable to make any sense out of it http://code.google.com/p/transdroid/issues/detail?id=14 the listview.xml layout file <?xml version="1.0" encoding="utf-8"?> <LinearLayout

  • Entity Framework 4 relationship management in POCO Templates - More lazy than FixupCollection?

    - by Joe Wood
    I've been taking a look at EF4 POCO templates in beta 2. The FixupCollection looks fine for maintaining the model correctness after updating the relationship collection property (i.e. product.Orders it would set the order.Product reference ). But what about support for handling the scenario when some of those Order objects are removed from the context? The use-case of maintaining cascading deletes in the in-memory model. The old Typed DataSet model used to do this by performing the query through the container to derive the relationship results. Like the DataSet, this would require a reference to the ObjectContext inside the entity class so that it could query the top-level Order collection. Better support for Separation of Concerns in the ObjectContext would be required. It looks like EF is not suited to this use-case that DataSets did out of the box.... am I right?

  • SubmitChanges doesn't save but removes inserts from change set, no errors

    - by winston schröder
    Hi Everybody, I have a deeper question regarding debug functionality of Linq to Sql SubmitChanges() Function. I want to save a record in a table of a locally cached db (localdbcache: server SqlExpress 2008 client SqlCE). Before calling SubmitChanges I can find the new item via DataContext.GetChangeSet(). After calling Submit Changes, the items to insert have been removed from the ChangeSet. (That's what this function is supposed to do.) There are no Changes Conflicts and no error in the db's log output. No Exception at all. The table's Count stays at the same value. if ((e.Parameter == null) || (!e.Parameter.GetType().Equals(typeof(LibDB.Client.Vehicles)))) return; LibDB.Client.Vehicles tmp = e.Parameter as LibDB.Client.Vehicles; try { ChangeSet cs = this._dc.GetChangeSet(); if ((tmp == null) || (this._dc == null)) return; if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 0) this._dc.Vehicles.InsertOnSubmit(tmp); else if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 1) this._dc.Vehicles.Attach(tmp, true); else return; using (TransactionScope ts = new TransactionScope()) { try { this._dc.SubmitChanges(); //this._dc.Refresh(RefreshMode.OverwriteCurrentValues, this._dc.Vehicles); } catch (Exception ex) { Console.WriteLine(ex.Message); } } if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 1) MessageBox.Show("Vehicle not saved."); this.vehSelector.ResetLayout(); } I would appreciate any help since I'm loosing hope to find any error, Thanks in Advance Winston

  • Invalid UTF-8 for Postgres, Perl thinks they're ok

    - by gorilla
    I'm running perl 5.10.0 and Postgres 8.4.3, and strings into a database, which is behind a DBIx::Class. These strings should be in UTF-8, and therefore my database is running in UTF-8. Unfortunatly some of these strings are bad, containing malformed UTF-8, so when I run it I'm getting an exception DBI Exception: DBD::Pg::st execute failed: ERROR: invalid byte sequence for encoding "UTF8": 0xb5 I thought that I could simply ignore the invalid ones, and worry about the malformed UTF-8 later, so using this code, it should flag & ignore the bad titles. if(not utf8::valid($title)){ $title="Invalid UTF-8"; } $data->title($title); $data->update(); However perl seems to think that the strings are valid, but it still throws the exceptions. How can I get perl to detect the bad UTF-8?

  • Access violation after GetInterface/QueryInterface in Delphi

    - by W55tKQbuRu28Q4xv
    Hi everyone! First, I'm very new in Delphi and COM, but I should build COM application in Delphi. I read a lot of articles and notes on the internets, but COM and COM in Delphi are still not clear to me. My sources - http://www.everfall.com/paste/id.php?wisdn8hyhzkt (about 80 lines). I try to make a COM Interface and Impl class - it works if I call an interface method from Delphi (I create an impl object via TestClient.Create), but if I try to create an object from outer world (from Java, via com4j) my application crashed with following exception: Project Kernel.exe raised exception class $C0000005 with message 'access violation at 0x00000002: read of address 0x00000002'. If I set a breakpoint in QueryInterface - it breaks, but when I come out from function - all crashes. What I'm doing wrong? What I still missing? What I can/should read about COM (in Delphi) to avoid dumb questions like this?

  • AutoMapper and SecurityException in IIS

    - by Felipe
    Hi everybody... I'm developing a asp.net mvc application with nhibernate and I would not like to expose my objects mappings with NHibernate, so I created DTO for each entity and I'm trying to convert my Domain objects to DTO and send it to View. So I have in my sollution: ClassLibrary with my Domain (for NHibernate) and DTO objetcs Class library to make a SessionFactory adn Factories in my Project Asp.Net MVC 2 Application So, I download AutoMapper to transform Domain objects in DTO and add a the code to do this in Application_Start of global.asax. When I run in VisualStudio (by pressing F5) it works fine and my dtos are into the view, So when I publish this in IIS, I get a security exception =( in first line of conversion: Mapper.CreateMap(); <--- this line throw exception Mapper.CreateMap(); System.Security.SecurityException: Failed request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. What can I do to resolve this to work in IIS ? When I will publish it on web server, the error will get too :( Thanks Cheers

  • Scope of Connection Object for a Website using Connection Pooling (Local or Instance)

    - by Danny
    For a web application with connection polling enabled, is it better to work with a locally scoped connection object or instance scoped connection object. I know there is probably not a big performance improvement between the two (because of the pooling) but would you say that one follows a better pattern than the other. Thanks ;) public class MyServlet extends HttpServlet { DataSource ds; public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } void SomeWork(String sql) { Connection conn = null; try { conn = ds.getConnection(); // execute some sql ..... } finally { if(conn != null) { conn.close(); // return to pool } } } } Or public class MyServlet extends HttpServlet { DataSource ds; Connection conn;* public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { try { conn = ds.getConnection(); SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } finally { if(conn != null) { conn.close(); // return to pool } } } void SomeWork(String sql) { // execute some sql ..... } }

  • Very simple Error handling with NServiceBus

    - by andy
    hey guys, here's a simple scenario NServiceBus Client/Server setup. The "Message" is a custom Class I wrote. The Client sends a request message. The Server receives the message, and the server does this: Bus.Reply(new UserDataResponseMessage { ID = Guid.NewGuid(), Response = users }); Then nothing. The Client never receives a response. Exception: By trawling through the log4net NServiceBus logs I find an exception, and it turns out that my customs class "users" is not marked as Serializable. Ok, how does one got about "throwing" or "handling" that kind of error? NServiceBus seems to promote the idea of not handling errors, but in this scenario its obvious to see some kind of "throw" would have saved a lot of time. How do I handle such exceptions, where do they occur, where do they go?

  • (1 2 3 . #<void>)- heapsort

    - by superguay
    Hello everybody: I tried to implement a "pairing heap" with all the regular operations (merge, delete-min etc.), then I've been requested to write a function that would sort a list using my newly constructed heap implementation. Unfortunately it seems that someting goes wrong... Here's the relevant code: (define (heap-merge h1 h2) (cond ((heap-empty? h1) h2) ((heap-empty? h2) h1) (else (let ((min1 (heap-get-min h1)) (min2 (heap-get-min h2))) (if ((heap-get-less h1) min1 min2) (make-pairing-heap (heap-get-less h1) min1 (cons h2 (heap-get-subheaps h1))) (make-pairing-heap (heap-get-less h1) min2 (cons h1 (heap-get-subheaps h2)))))))) (define (heap-insert element h) (heap-merge (make-pairing-heap (heap-get-less h) element '()) h)) (define (heap-delete-min h) (define (merge-in-pairs less? subheaps) (cond ((null? subheaps) (make-heap less?)) ((null? (cdr subheaps)) (car subheaps)) (else (heap-merge (heap-merge (car subheaps) (cadr subheaps)) (merge-in-pairs less? (cddr subheaps)))))) (if (heap-empty? h) (error "expected pairing-heap for first argument, got an empty heap ") (merge-in-pairs (heap-get-less h) (heap-get-subheaps h)))) (define (heapsort l less?) (let aux ((h (accumulate heap-insert (make-heap less?) l))) (if (not (heap-empty? h)) (cons (heap-get-min h) (aux (heap-delete-min h)))))) And these are some selectors that may help you to understand the code: (define (make-pairing-heap less? min subheaps) (cons less? (cons min subheaps))) (define (make-heap less?) (cons less? '())) (define (heap-get-less h) (car h)) (define (heap-empty? h) (if (null? (cdr h)) #t #f)) Now lets get to the problem: When i run 'heapsort' it returns the sorted list with "void", as you can see: (heapsort (list 1 2 3) <) (1 2 3 . #)..HOW CAN I FIX IT? Regards, Superguay

  • libcurl .NET does not want to work on Win64

    - by Dmitry
    I wrote multi-threaded FTP uploader on C#.NET using libcurl.NET. Everything works fine on my machine, but when I give application (exe + libcurl.dll + 2 libcurl C# binding DLLs) to my friend who is running Win64, application crashes. After adding exception catcher to whole Main() function, I was able to get readable error message: "An attempt was made to load a program with an incorrect format (Exception from HRESULT = 0x8007000b)" After googling for a while, I found an advice to enable unmanaged code in my project settings. I've recompiled my application and LibCurlNet.dll with this flag set but it did not help. What can cause such problem?

  • System.IO.IOException: file used by another process

    - by Srodriguez
    Dear all, I've been working in this small piece of code that seems trivial but still i cannot really see where is the problem. My functions does a pretty simple thing. Opens a file, copy its contents, replace a string inside and copy it back to the original file (a simple search and replace inside a text file then). I didn't really know how to do that as I'm adding lines to the original file, so i just create a copy of the file, (file.temp) copy also a backup (file.temp) then delete the original file(file) and copy the file.temp to file. I get an exception while doing the delete of the file. Here is the sample code: private static bool modifyFile(FileInfo file, string extractedMethod, string modifiedMethod) { Boolean result = false; FileStream fs = new FileStream(file.FullName + ".tmp", FileMode.Create, FileAccess.Write); StreamWriter sw = new StreamWriter(fs); StreamReader streamreader = file.OpenText(); String originalPath = file.FullName; string input = streamreader.ReadToEnd(); Console.WriteLine("input : {0}", input); String tempString = input.Replace(extractedMethod, modifiedMethod); Console.WriteLine("replaced String {0}", tempString); try { sw.Write(tempString); sw.Flush(); sw.Close(); sw.Dispose(); fs.Close(); fs.Dispose(); streamreader.Close(); streamreader.Dispose(); File.Copy(originalPath, originalPath + ".old", true); FileInfo newFile = new FileInfo(originalPath + ".tmp"); File.Delete(originalPath); File.Copy(fs., originalPath, true); result = true; } catch (Exception ex) { Console.WriteLine(ex); } return result; }` And the related exception System.IO.IOException: The process cannot access the file 'E:\mypath\myFile.cs' because it is being used by another process. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.Delete(String path) at callingMethod.modifyFile(FileInfo file, String extractedMethod, String modifiedMethod) Normally these errors come from unclosed file streams, but I've taken care of that. I guess I've forgotten an important step but cannot figure out where. Thank you very much for your help,

  • .NET: IOException for permissions when creating new file?

    - by Rosarch
    I am trying to create a new file and write XML to it: FileStream output = File.Create(Path.Combine(PATH_TO_DATA_DIR, fileName)); The argument evaluates to: C:\path\to\Data\test.xml The exception is: The process cannot access the file 'C:\path\to\Data\test.xml' because it is being used by another process. What am I doing wrong here? UPDATE: This code throws the same exception: StreamWriter writer = new StreamWriter(Path.Combine(PATH_TO_DATA_DIR, fileName)); UPDATE 2: The file I am trying to create does not exist in the file system. So how can be it in use?

  • Dependency Property on ValueConverter

    I'm trying to initialize a converter in the Resources section of my UserControl with a reference to one of the objects in my control.

  • onload Event in embedded SVG not calling function in attached script. Scope Issue?

    - by Nick
    Hi So I've got an XHTML page with a script - not inline > <script type="text/javascript" > src="../global/js/scripts.js"></script> and an embedded (I tried embed and object, same behavior) SVG document with a onload="CheckIfLoaded(evt)" attribute. The problem is firefox doesn't call the CheckIfLoaded() function in scripts.js. Firebug gives me "CheckIfLoaded() is not defined" with no reference to any line numbers. I can't find any information regarding the scope of javascript functions with respect to embedded content. Curiously, it works fine in IE. I could of course add a reference to the script into the SVG file as well but I believe that will result in the client downloading the scripts file twice and in addition I have 1000+ svg files and I'd really rather not add one line to all of them, although I suppose I could write a batch file or whatever if I have to. Any one know more about this? Thanks, Nick

  • AsyncTask, RejectedExecutionException and Task Limit

    - by Samuh
    I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. I get RejectedExecution exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty catch(RejectedException e){} block?) I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3). [EDIT: Added SDK and API level info]

  • How bad is code using std::basic_string<t> as a contiguous buffer?

    - by BillyONeal
    I know technically the std::basic_string template is not required to have contiguous memory. However, I'm curious how many implementations exist for modern compilers that actually take advantage of this freedom. For example, if one wants code like the following it seems silly to allocate a vector just to turn around instantly and return it as a string: DWORD valueLength = 0; DWORD type; LONG errorCheck = RegQueryValueExW( hWin32, value.c_str(), NULL, &type, NULL, &valueLength); if (errorCheck != ERROR_SUCCESS) WindowsApiException::Throw(errorCheck); else if (valueLength == 0) return std::wstring(); std::wstring buffer; do { buffer.resize(valueLength/sizeof(wchar_t)); errorCheck = RegQueryValueExW( hWin32, value.c_str(), NULL, &type, &buffer[0], &valueLength); } while (errorCheck == ERROR_MORE_DATA); if (errorCheck != ERROR_SUCCESS) WindowsApiException::Throw(errorCheck); return buffer; I know code like this might slightly reduce portability because it implies that std::wstring is contiguous -- but I'm wondering just how unportable that makes this code. Put another way, how may compilers actually take advantage of the freedom having noncontiguous memory allows? Oh: And of course given what the code's doing this only matters for Windows compilers.

  • Silverlight ViewBase in separate assembly - possible?

    - by Mark
    I have all my views in a project inheriting from a ViewBase class that inherits from UserControl. In my XAML I reference it thus: <f:ViewBase x:Class="Forte.UI.Modules.Configure.Views.AddNewEmployeeView" xmlns:f="clr-namespace:Forte.UI.Modules.Configure.Views" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" It works fine. Now I have moved the ViewBase to another project (so I can refernce it from multiple projects) so I reference it like: <f:ViewBase x:Class="Forte.UI.Modules.Configure.Views.AddNewEmployeeView" xmlns:f="clr-namespace:Forte.UI.Modules.Common.Views;assembly=Forte.UI.Modules.Common" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" This works fine when I run from the IDE but when I run the same sln from MSBuild it gives a warning: "H:\dev\ExternalCopy\Code\UI\Modules\Configure\Forte.UI.Modules.Configure.csproj" (default target) (10:12) - (ValidateXaml target) - H:\dev\ExternalCopy\Code\UI\Modules\Configure\Views\AddNewEmployee\AddNewEmployeeView.xaml(1,2,1,2): warning : The tag 'ViewBase' does not exist in XML namespace 'clr-namespace:Forte.UI.Modules.Common.Views;assembly=Forte.UI.Modules.Common'.

  • Pixel shader wierd compilation error

    - by ytrewq
    hi, I'm experiencing with shaders a bit and I keep getting this weird compilation error that's driving me crazy! the following pixel shader code snippet: DirectionVector = normalize(f3LightPosition[i] - PixelPos); LightVec = PixelNormal - DirectionVector; // Get the light strenght factor LightStrFactor = float(abs((LightVec.x + LightVec.y + LightVec.z) / 3.0f)); // TEST!!! LightStrFactor = 1.0f; // Add this light to the total light on this pixel LightVal += f4Light[i] * LightStrFactor; works perfectly, but as soon as i remove the "LightStrFactor = 1.0f;" line, i.e. letting 'LightStrFactor ' value be the result of the calculation above, it fails to compile the shader. LightStrFactor is a float LightVal & f4Light[i] are float4 All the rest are float3. my question is, besides why it doesn't compile, is how come DX compiler cares about the value of a float? even if my values are incorrect, shouldn't it be run-time? the shader compilation code is this: /* Compile the bitch */ if (FAILED(D3DXCompileShaderFromFile(fileName, NULL, NULL, "PS_MAIN", "ps_2_0", 0, &this->m_pCode, NULL, &this->m_constantTable))) GraphicException("Failed to compile pixel shader!"); // <-- gets here :( if (FAILED(g_D3dDevice->CreatePixelShader( (DWORD*)this->m_pCode->GetBufferPointer(), &this->m_hPixelShader ))) GraphicException("Failed to create pixel shader!"); this->m_fLoaded = true; any help is appreciated thanks!!! :]

  • Index was outside the bounds of the array. IndexOutOfRangeException in LINQ to SQL

    - by gtas
    Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

  • Could not load file or assembly log4net or one of its dependencies

    - by Elie
    I've been asked to take a look at an error in an ASP/C# application with its Paypal integration. The error, shown in full, is: Could not load file or assembly 'log4net, Version=1.2.0.30714, Culture=neutral, PublicKeyToken=b32731d11ce58905' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) From what I understand, this means that the actual file located (that is, log4net.dll in my bin directory) does not match the version expected based on some assembly configuration. The problem I'm having is that I cannot locate where this file is being referenced. I have access to all the files in the web root directory of the site, and cannot locate any config files that reference this DLL. Where else might I need to look to determine what's causing the mis-match? As a note, I've made sure that the version of the DLL in the bin directory is up to date, but this does not seem to have resolved anything.
