• Handling async ASMX web service exceptions

  - by Andy

  Hi, I've developed silverlight client with makes async web services calls to a asmx web service. The problem is, I want to handle exceptions, so far as to be able to tell in the client application whether there was an exception in the webservice (and therefore will be logged local to the webservice) or whether there was a communication problem (i.e. the endpoint for the webservice was wrong). In testing both types of exceptions in my project I get the same generic exception: System.ServiceModel.CommunicationException: The remote server returned an error: NotFound. This exception is amazingly useless when an exception occured in the webservice as it clearly has been found. Is the presence of this generic error to do with security (not being allowed to see true errors)? It can't be the fact that I don't have debug strings as I'm running on a dev PC. Either way, my question is, what's the best way to handle async errors in a commercial silverlight application? Any links or ideas are most welcome! :) Thanks a lot! Andy.

• "Microsoft.ACE.OLEDB.12.0 provider is not registered" [RESOLVED]

  - by Azim

  I have a Visual Studio 2008 solution with two projects (a Word-Template project and a VB.Net console application for testing). Both projects reference a database project which opens a connection to an MS-Access 2007 database file and have references to System.Data.OleDb. In the database project I have a function which retrieves a data table as follows private class AdminDatabase ' stores the connection string which is set in the New() method dim strAdminConnection as string public sub New() ... adminName = dlgopen.FileName conAdminDB = New OleDbConnection conAdminDB.ConnectionString = "Data Source='" + adminName + "';" + _ "Provider=Microsoft.ACE.OLEDB.12.0" ' store the connection string in strAdminConnection strAdminConnection = conAdminDB.ConnectionString.ToString() My.Settings.SetUserOverride("AdminConnectionString", strAdminConnection) ... End Sub ' retrieves data from the database Public Function getDataTable(ByVal sqlStatement As String) As DataTable Dim ds As New DataSet Dim dt As New DataTable Dim da As New OleDbDataAdapter Dim localCon As New OleDbConnection localCon.ConnectionString = strAdminConnection Using localCon Dim command As OleDbCommand = localCon.CreateCommand() command.CommandText = sqlStatement localCon.Open() da.SelectCommand = command da.Fill(dt) getDataTable = dt End Using End Function End Class When I call this function from my Word 2007 Template project everything works fine; no errors. But when I run it from the console application it throws the following exception ex = {"The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine."} Both projects have the same reference and the console application did work when I first wrote it (a while ago) but now it has stopped work. I must be missing something but I don't know what. Any ideas?

• How to make Delphi Prism indexed properties visible to C# when properties are not default

  - by Arcturus

  I have several Delphi Prism classes with indexed properties that I use a lot on my C# web applications (we are migrating a big Delphi Win32 system to ASP.Net). My problem is that it seems that C# can't see the indexed properties if they aren't the default properties of their classes. Maybe I'm doing something wrong, but I'm completely lost. I know that this question looks a lot like a bug report, but I need to know if someone else knows how to solve this before I report a bug. If I have a class like this: TMyClass = public class private ... method get_IndexedBool(index: Integer): boolean; method set_IndexedBool(index: Integer; value: boolean); public property IndexedBool[index: Integer]: boolean read get_IndexedBool write set_IndexedBool; default; // make IndexedBool the default property end; I can use this class in C# like this: var myObj = new TMyClass(); myObj[0] = true; However, if TMyClass is defined like this: TMyClass = public class private ... method get_IndexedBool(index: Integer): boolean; method set_IndexedBool(index: Integer; value: boolean); public property IndexedBool[index: Integer]: boolean read get_IndexedBool write set_IndexedBool; // IndexedBool is not the default property anymore end; Then the IndexedBool property becomes invisible in C#. The only way I can use it is doing this: var myObj = new TMyClass(); myObj.set_IndexedBool(0, true); I don't know if I'm missing something, but I can't see the IndexedBool property if I remove the default in the property declaration. Besides that, I'm pretty sure that it is wrong to have direct access to a private method of a class instance. Any ideas?

• ASP.Net FormsAuthentication Redirect Loses the cookie between Redirect and Application_AuthenticateR

  - by Joel Etherton

  I have a FormsAuthentication cookie that is persistent and works independently in a development, test, and production environment. I have a user that can authenticate, the user object is created, the authentication cookie is added to the response: 'Custom object to grab the TLD from the url authCookie.Domain = myTicketModule.GetTopLevelDomain(Request.ServerVariables("HTTP_HOST")) FormsAuthentication.SetAuthCookie(authTicket.Name, False) Response.SetCookie(authCookie) The user gets processed a little bit to check for a first time login, security questions, etc, and is then redirected with the following tidbit: Session.Add("ForceRedirect", "/FirstTimeLogin.aspx") Response.Redirect("~/FirstTimeLogin.aspx", True) With a debug break, I can verify that the cookie collection holds both a cookie not related to authentication that I set for a different purpose and the formsauthentication cookie. Then the next step in the process occurs at the ApplicationAuthenticateRequest in the global.asax: Sub Application_AuthenticateRequest(ByVal sender As Object, ByVal e As EventArgs) Dim formsCookieName As String = myConfigurationManager.AppSettings("FormsCookieName") Dim authCookie As HttpCookie = Request.Cookies(formsCookieName) At this point, for this ONE user authCookie is nothing. I have 15,000 other users who are not impacted in this manner. However, for one user the cookie just vanishes without a trace. I've seen this before with w3wp.exe exceptions, state server exceptions and other IIS process related exceptions, but I'm getting no exceptions in the event log. w3wp.exe is not crashing, the state server has some timeouts but they appear unrelated (as verified by timestamps) and it only happens to this one user on this one domain (this code is used across 2 different TLDs with approximately 10 other subdomains). One avenue I'm investigating is that the cookie might just be too large. I would think that there would be a check for the size of the cookie going into the response, and I wouldn't think it would impact it this way. Any ideas why the request might dumping the cookie? NOTE: The secondary cookie I mentioned that I set also gets dumped (and it's very tiny). EDIT-NOTE: The session token is NOT lost when this happens. However, since the authentication cookie is lost, it is ignored and replaced on a subsequent login.

• Common Table Expressions slow when using a table variable

  - by Phil Haselden

  I have been experimenting with the following (simplified) CTE. When using a table variable () the query runs for minutes before I cancel it. Any of the other commented out methods return in less than a second. If I replace the whole WHERE clause with an INNER JOIN it is fast as well. Any ideas why using a table variable would run so slowly? FWIW: The database contains 2.5 million records and the inner query returns 2 records. CREATE TABLE #rootTempTable (RootID int PRIMARY KEY) INSERT INTO #rootTempTable VALUES (1360); DECLARE @rootTableVar TABLE (RootID int PRIMARY KEY); INSERT INTO @rootTableVar VALUES (1360); WITH My_CTE AS ( SELECT ROW_NUMBER() OVER(ORDER BY d.DocumentID) rownum, d.DocumentID, d.Title FROM [Document] d WHERE d.LocationID IN ( SELECT LocationID FROM Location JOIN @rootTableVar rtv ON Location.RootID = rtv.RootID -- VERY SLOW! --JOIN #rootTempTable tt ON Location.RootID = tt.RootID -- Fast --JOIN (SELECT 1360 as RootID) AS rt ON Location.RootID = rt.RootID -- Fast --WHERE RootID = 1360 -- Fast ) ) SELECT * FROM My_CTE WHERE (rownum > 0) AND (rownum <= 100) ORDER BY rownum

• JQuery tools.scrollable conflict with navbar Ajax in CakePHP

  - by user269098

  In our views/layout/default.ctp file we have an element that's used to implement a cascading combo select box which uses JQuery ajax to update the fields. This selector is part of our navbar and is loaded on every page of the site. The default.ctp has these includes in the : <?php echo $html->charset(); ?> <title><?php echo $title_for_layout; //if(Configure::read('debug')) //echo "cake: " . Configure::version(); ?></title> <?php echo $html->css('style'); echo $javascript->link('jquery', true); echo $javascript->link('jquery.form', true); echo $javascript->link('jquery.url', true); echo $javascript->link('navbar', true); echo $html->script('tools.expose-1.0.3.js', array('inline' => false)); //echo $scripts_for_layout; ?> On the views/cars/index.ctp page we have: echo $javascript->link('tools.tabs-1.0.1', true); echo $javascript->link('tools.overlay-1.0.4', true); echo $javascript->link('jquery.form', true); echo $javascript->link('tools.scrollable-1.0.5', true); The issue is that on every other page the navbar combo box selector works. However, on the cars/index.ctp it doesn't work. It only works when we comment out the 'tools.scrollable' include. Any ideas why there is this conflict? We have been stuck on this problem for months...

• WPF RelativeSource FindAncestor doesn't work outside of the Control.Resources context?

  - by sker

  I have this VisualBrush resource I took from some site and I apply it with triggers to a TextBox. <VisualBrush x:Key="HelpBrush" TileMode="None" Opacity="0.4" Stretch="None" AlignmentX="Left"> <VisualBrush.Visual> <TextBlock FontStyle="Italic" Text="{Binding Path=Tag, RelativeSource={RelativeSource AncestorType={x:Type Control}, AncestorLevel=1}}"/> </VisualBrush.Visual> </VisualBrush> <Style x:Key="DefaultText" TargetType="TextBox"> <Style.Triggers> <Trigger Property="Text" Value="{x:Null}"> <Setter Property="Background" Value="{StaticResource HelpBrush}"/> </Trigger> <Trigger Property="Text" Value=""> <Setter Property="Background" Value="{StaticResource HelpBrush}"/> </Trigger> </Style.Triggers> </Style> If I place both the VisualBrush and the Style inside the TextBox.Resources tag in XAML, it works fine. But if I take it out and place it in the Window.Resources or a merged dictionary, it stops working. The problem is the Binding, it doesn't find the ancestor TextBox for some reason. I already tried removing AncestorLevel and using AncestorType={x:Type TextBox} - it doesn't work. Any ideas?

• Why does Adding Core Animation slow down drawing of my NSTableView?

  - by Will Goring

  I have a simple App that displays a list of items using NSTableView. There are usually about 15-25 items in the list, and the table has 10 columns, all but one of which are text (the other's an icon.) There are simple data transformers on a couple of the columns. So nothing taxing; you'd expect it to run just fine. And as it stands, it is; the app is responsive and everything draws pretty much instantly. Scrolling, changing column sizes, resizing the window; whatever you do the redraws keep up with the mouse-pointer. Tonight, I thought I'd try adding a little visual flair to the app with Core Animation (which I've never used before,) but I've found that if anything above the NSTableView in the hierarchy is set 'Wants Core Animation Layer,' then the NSTableView redraws go to hell. Scrolling is usually fine, but resizing columns or the window causes it to pick up an effect like texture tearing, where some of the rows have the new size, and some have the old one, and everything flickers horribly. It looks terrible. Basically it looks like what you'd expect if rendering the individual rows or columns was taking a long time. I've put it through Shark and, sure enough, it looks like it's spending most of its time drawing the text in the cells; what I don't understand is why that should take longer when there's a Core Animation layer involved than when there isn't - and quite noticeably longer at that. Has anyone got any ideas? Is there any Core Animation initialisation or config I've missed or something (I've literally just ticked the "Wants Core Animation Layer" box in IB)? Cheers, Will

• crystal reports : cannot determine the queries necessary to get data for this report

  - by phill

  I've recently come across the following error in one of my crystal reports following an accounting system update. Group #1: ? - A : This group section cannot be printed because its condition field is nonexistent or invalid. Format the section to choose another condition field. I've verified every database field being used to ensure it still exists for consistency and checked the formulas for that section. No dice. So to hopefully fix the problem, i remove the section using the Section expert. I run the same database checks. It then complains with the same error for Group #5. So i remove that as well. now I have a new and unusual error when i attempt to run 'Show Query'. the error is: "Cannot determine the queries necessary to get data for this report" I have tried to logon/logoff the database and verify database. No complaints until i try to run, show query. When I attempt to run the report, it also throws the same error. any ideas? Am I approaching this incorrectly? this is done in crystal reports 10. note: this report is run with the sql sa user to eliminate any permission issues.

• Authenticating Windows 7 against MIT Kerberos 5

  - by tommed

  Hi There, I've been wracking my brains trying to get Windows 7 authenticating against a MIT Kerberos 5 Realm (which is running on an Arch Linux server). I've done the following on the server (aka dc1): Installed and configured a NTP time server Installed and configured DHCP and DNS (setup for the domain tnet.loc) Installed Kerberos from source Setup the database Configured the keytab Setup the ACL file with: *@TNET.LOC * Added a policy for my user and my machine: addpol users addpol admin addpol hosts ank -policy users [email protected] ank -policy admin tom/[email protected] ank -policy hosts host/wdesk3.tnet.loc -pw MYPASSWORDHERE I then did the following to the windows 7 client (aka wdesk3): Made sure the ip address was supplied by my DHCP server and dc1.tnet.loc pings ok Set the internet time server to my linux server (aka dc1.tnet.loc) Used ksetup to configure the realm: ksetup /SetRealm TNET.LOC ksetup /AddKdc dc1.tnet.loc ksetip /SetComputerPassword MYPASSWORDHERE ksetip /MapUser * * After some googl-ing I found that DES encryption was disabled by Windows 7 by default and I turned the policy on to support DES encryption over Kerberos Then I rebooted the windows client However after doing all that I still cannot login from my Windows client. :( Looking at the logs on the server; the request looks fine and everything works great, I think the issue is that the response from the KDC is not recognized by the Windows Client and a generic login error appears: "Login Failure: User name or password is invalid". The log file for the server looks like this (I tail'ed this so I know it's happening when the Windows machine attempts the login): If I supply an invalid realm in the login window I get a completely different error message, so I don't think it's a connection problem from the client to the server? But I can't find any error logs on the Windows machine? (anyone know where these are?) If I try: runas /netonly /user:[email protected] cmd.exe everything works (although I don't get anything appear in the server logs, so I'm wondering if it's not touching the server for this??), but if I run: runas /user:[email protected] cmd.exe I get the same authentication error. Any Kerberos Gurus out there who can give me some ideas as to what to try next? pretty please?

• Context migration in CUDA.NET

  - by Vyacheslav

  I'm currently using CUDA.NET library by GASS. I need to initialize cuda arrays (actually cublas vectors, but it doesn't matters) in one CPU thread and use them in other CPU thread. But CUDA context which holding all initialized arrays and loaded functions, can be attached to only one CPU thread. There is mechanism called context migration API to detach context from one thread and attach it to another. But i don't how to properly use it in CUDA.NET. I tried something like this: class Program { private static float[] vector1, vector2; private static CUDA cuda; private static CUBLAS cublas; private static CUdeviceptr ptr; static void Main(string[] args) { cuda = new CUDA(false); cublas = new CUBLAS(cuda); cuda.Init(); cuda.CreateContext(0); AllocateVectors(); cuda.DetachContext(); CUcontext context = cuda.PopCurrentContext(); GetVectorFromDeviceAsync(context); } private static void AllocateVectors() { vector1 = new float[]{1f, 2f, 3f, 4f, 5f}; ptr = cublas.Allocate(vector1.Length, sizeof (float)); cublas.SetVector(vector1, ptr); vector2 = new float[5]; } private static void GetVectorFromDevice(object objContext) { CUcontext localContext = (CUcontext) objContext; cuda.PushCurrentContext(localContext); cuda.AttachContext(localContext); //change vector somehow vector1[0] = -1; //copy changed vector to device cublas.SetVector(vector1, ptr); cublas.GetVector(ptr, vector2); CUDADriver.cuCtxPopCurrent(ref localContext); } private static void GetVectorFromDeviceAsync(CUcontext cUcontext) { Thread thread = new Thread(GetVectorFromDevice); thread.IsBackground = false; thread.Start(cUcontext); } } But execution fails on attempt to copy changed vector to device because context is not attached? Any ideas how i can get it work?

• VS2010 RC: Add new domain service class wizard entities list is empty

  - by Matthew

  Greetings! I am going through Brad Abrams' SL4 + RIA Services series. Right now I am here: http://blogs.msdn.com/brada/archive/2010/03/15/silverlight-4-ria-services-ready-for-business-exposing-data-from-entity-framework.aspx. When I get to the "add domain service" step and the wizard asks you what entities you want to expose, the list is empty. The dropdown that let's me choose my Entity data context is there and the "DishViewEntities" is selected but it is not showing the "Restaurant" and "Plate" entities in the list below like it does in the picture. I found this thread here: http://forums.silverlight.net/forums/t/168724.aspx. The poster has the same problem as me. I have restarted VS, rebooted, regenerated the EDMX, tried creating it in different folders. Still the list is empty. When it is empty, it will not allow me to select individual entities or generate the class. Any ideas from the community? Thanks!

• Complex SQL Query similar to a z order problem

  - by AaronLS

  I have a complex SQL problem in MS SQL Server, and in drawing on a piece of paper I realized that I could think of it as a single bar filled with rectangles, each rectangle having segments with different Z orders. In reality it has nothing to do with z order or graphics at all, but more to do with some complex business rules that would be difficult to explain. Howoever, if anyone has ideas on how to solve the below that will give me my solution. I have the following data: ObjectID, PercentOfBar, ZOrder (where smaller is closer) A, 100, 6 B, 50, 5 B, 50, 4 C, 30, 3 C, 70, 6 The result of my query that I want is this, in any order: PercentOfBar, ZOrder 50, 5 20, 4 30, 3 Think of it like this, if I drew rectangle A, it would fill 100% of the bar and have a z order of 6. 66666666666 AAAAAAAAAAA If I then layed out rectangle B, consisting of two segments, both segments would cover up rectangle A resulting in the following rendering: 4444455555 BBBBBBBBBB As a rule of thumb, for a given rectangle, it's segments should be layed out such that the highest z order is to the right of the lower Z orders. Finally rectangle C would cover up only portions of Rectangle B with it's 30% segment that is z order 3, which would be on the left. You can hopefully see how the is represented in the output dataset I listed above: 3334455555 CCCBBBBBBB Now to make things more complicated I actually have a 4th column such that this grouping occurs for each key: Input: SomeKey, ObjectID, PercentOfBar, ZOrder (where smaller is closer) X, A, 100, 6 X, B, 50, 5 X, B, 50, 4 X, C, 30, 3 X, C, 70, 6 Y, A, 100, 6 Z, B, 50, 2 Z, B, 50, 6 Z, C, 100, 5 Output: SomeKey, PercentOfBar, ZOrder X, 50, 5 X, 20, 4 X, 30, 3 Y, 100, 6 Z, 50, 2 Z, 50, 5 Notice in the output, the PercentOfBar for each SomeKey would add up to 100%. This is one I know I'm going to be thinking about when I go to bed tonight. Just to be explicit and have a question: What would be a query that would produce the results described above?

• OCR with Neural network: data extraction

  - by Sebastian Hoitz

  I'm using the AForge library framework and its neural network. At the moment when I train my network I create lots of images (one image per letter per font) at a big size (30 pt), cut out the actual letter, scale this down to a smaller size (10x10 px) and then save it to my harddisk. I can then go and read all those images, creating my double[] arrays with data. At the moment I do this on a pixel basis. So once I have successfully trained my network I test the network and let it run on a sample image with the alphabet at different sizes (uppercase and lowercase). But the result is not really promising. I trained the network so that RunEpoch had an error of about 1.5 (so almost no error), but there are still some letters left that do not get identified correctly in my test image. Now my question is: Is this caused because I have a faulty learning method (pixelbased vs. the suggested use of receptors in this article: http://www.codeproject.com/KB/cs/neural_network_ocr.aspx - are there other methods I can use to extract the data for the network?) or can this happen because my segmentation-algorithm to extract the letters from the image to look at is bad? Does anyone have ideas on how to improve it?

• Does Django cache url regex patterns somehow?

  - by Emre Sevinç

  I'm a Django newbie who needs help: Even though I change some urls in my urls.py I keep on getting the same error message from Django. Here is the relevant line from my settings.py: ROOT_URLCONF = 'mydjango.urls' Here is my urls.py: from django.conf.urls.defaults import * # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', # Example: # (r'^mydjango/', include('mydjango.foo.urls')), # Uncomment the admin/doc line below and add 'django.contrib.admindocs' # to INSTALLED_APPS to enable admin documentation: #(r'^admin/doc/', include(django.contrib.admindocs.urls)), # (r'^polls/', include('mydjango.polls.urls')), (r'^$', 'mydjango.polls.views.homepage'), (r'^polls/$', 'mydjango.polls.views.index'), (r'^polls/(?P<poll_id>\d+)/$', 'mydjango.polls.views.detail'), (r'^polls/(?P<poll_id>\d+)/results/$', 'mydjango.polls.views.results'), (r'^polls/(?P<poll_id>\d+)/vote/$', 'mydjango.polls.views.vote'), (r'^polls/randomTest1/', 'mydjango.polls.views.randomTest1'), (r'^admin/', include(admin.site.urls)), ) So I expect that whenever I visit http://mydjango.yafz.org/polls/randomTest1/ the mydjango.polls.views.randomTest1 function should run because in my polls/views.py I have the relevant function: def randomTest1(request): # mainText = request.POST['mainText'] return HttpResponse("Default random test") However I keep on getting the following error message: Page not found (404) Request Method: GET Request URL: http://mydjango.yafz.org/polls/randomTest1 Using the URLconf defined in mydjango.urls, Django tried these URL patterns, in this order: 1. ^$ 2. ^polls/$ 3. ^polls/(?P<poll_id>\d+)/$ 4. ^polls/(?P<poll_id>\d+)/results/$ 5. ^polls/(?P<poll_id>\d+)/vote/$ 6. ^admin/ 7. ^polls/randomTest/$ The current URL, polls/randomTest1, didn't match any of these. I'm surprised because again and again I check urls.py and there is no ^polls/randomTest/$ in it, but there is ^polls/randomTest1/' It seems like Django is somehow storing the previous contents of urls.py and I just don't know how to make my latest changes effective. Any ideas? Why do I keep on seeing some old version of regexes when I try to load that page even though I changed my urls.py?

• ASP.net MVC HttpException strange file not found

  - by Paddy

  I'm running asp.net MVC site on IIS6 - I've edited my routing to look like the following: routes.MapRoute( "Default", "{controller}.aspx/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); routes.MapRoute( "Root", "", new { controller = "Home", action = "Index", id = "" } ); So all my urls now contain .aspx (as per one of the solutions from Phil Haack). Now, I catch all unhandled exceptions using Elmah, and for almost every page request, I get the following error caught by Elmah, that I never see on the front end (everything works perfectly): System.Web.HttpException: The file '/VirtualDirectoryName/Home.aspx' does not exist.

Any ideas? Edited with answer: I think the answer for this can be found in this question: http://stackoverflow.com/questions/34194/asp-net-mvc-on-iis6

• Nokogiri pull parser (Nokogiri::XML::Reader) issue with self closing tag

  - by Vlad Zloteanu

  I have a huge XML(400MB) containing products. Using a DOM parser is therefore excluded, so i tried to parse and process it using a pull parser. Below is a snippet from the each_product(&block) method where i iterate over the product list. Basically, using a stack, i transform each <product> ... </product> node into a hash and process it. while (reader.read) case reader.node_type #start element when Nokogiri::XML::Node::ELEMENT_NODE elem_name = reader.name.to_s stack.push([elem_name, {}]) #text element when Nokogiri::XML::Node::TEXT_NODE, Nokogiri::XML::Node::CDATA_SECTION_NODE stack.last[1] = reader.value #end element when Nokogiri::XML::Node::ELEMENT_DECL return if stack.empty? elem = stack.pop parent = stack.last if parent.nil? yield(elem[1]) elem = nil next end key = elem[0] parent_childs = parent[1] # ... parent_childs[key] = elem[1] end The issue is on self-closing tags (EG <country/>), as i can not make the difference between a 'normal' and a 'self-closing' tag. They both are of type Nokogiri::XML::Node::ELEMENT_NODE and i am not able to find any other discriminator in the documentation. Any ideas on how to solve this issue?

• iPhone SDK linking errors with static library

  - by Nico

  Hello all! I've built my own static library with components to be reused in my project, and recently had the need to update a bunch of classes. Specifically, some methods' signatures were changed due to the fact that some classes changed names. What happens now is that the library compiles fine on its own, but, when added to an app project, the project fails to link: Ld build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales normal armv6 cd /Users/nameghino/src/Sucursales setenv IPHONEOS_DEPLOYMENT_TARGET 3.1 setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk -L/Users/nameghino/src/Sucursales/build/Debug-iphoneos -L/Users/nameghino/src/Sucursales/../../Library/MyLibraries/MSSharedLibrary-1.0.0 -F/Users/nameghino/src/Sucursales/build/Debug-iphoneos -filelist /Users/nameghino/src/Sucursales/build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales.LinkFileList -dead_strip -lxml2 -ObjC -all_load -miphoneos-version-min=3.1 -framework Foundation -framework UIKit -framework CoreGraphics -lsqlite3.0 -framework CoreLocation -framework MapKit -lxml2 /Users/nameghino/src/MSSharedComponents/Frameworks/MSSharedLibrary/build/Debug-iphoneos/libMSSharedLibrary.a -o /Users/nameghino/src/Sucursales/build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales Undefined symbols: "_OBJC_CLASS_$_DataCatalogService_GetSingleRow", referenced from: objc-class-ref-to-DataCatalogService_GetSingleRow in libMSSharedLibrary.a(MSDataCatalogSpecification.o) **"_OBJC_CLASS_$_DataCatalogService_ArrayOfString", referenced from: objc-class-ref-to-DataCatalogService_ArrayOfString in libMSSharedLibrary.a(MSDataCatalogSpecification.o) "_OBJC_CLASS_$_DataCatalogService_GetSingleRowResponse", referenced from: objc-class-ref-to-DataCatalogService_GetSingleRowResponse in libMSSharedLibrary.a(MSSingleRowResultsParser.o) "_OBJC_CLASS_$_DataCatalogService_GetMultiRowResponse", referenced from: objc-class-ref-to-DataCatalogService_GetMultiRowResponse in libMSSharedLibrary.a(MSMultiRowResultsParser.o) "_OBJC_CLASS_$_DataCatalogService_GetMultiRow", referenced from: objc-class-ref-to-DataCatalogService_GetMultiRow in libMSSharedLibrary.a(MSDataCatalogSpecification.o) "_OBJC_CLASS_$_DataCatalogService_HelloWorldResponse", referenced from: objc-class-ref-to-DataCatalogService_HelloWorldResponse in libMSSharedLibrary.a(DataCatalogService.o) ld: symbol(s) not found collect2: ld returned 1 exit status** The curious thing is that after a lot of project cleanups (both in the app and the lib projects), I still get the same issue.

• iPod/iPhone OpenGL ES UIView flashes when updating

  - by Dave Viner

  I have a simple iPhone application which uses OpenGL ES (v1) to draw a line based on the touches of the user. In the XCode Simulator, the code works perfectly. However, when I install the app onto an iPod or iPhone, the OpenGL ES view "flashes" when drawing the line. If I disable the line drawing, the flash disappears. By "flash", I mean that the background image (which is an OpenGL texture) disappears momentarily, and then reappears. It appears as if the entire scene is completely erased and redrawn. The code which handles the line drawing is the following: renderLineFromPoint:(CGPoint)start toPoint:(CGPoint)end { static GLfloat* vertexBuffer = NULL; static NSUInteger vertexMax = 64; NSUInteger vertexCount = 0, count, i; //Allocate vertex array buffer if(vertexBuffer == NULL) vertexBuffer = malloc(vertexMax * 2 * sizeof(GLfloat)); //Add points to the buffer so there are drawing points every X pixels count = MAX(ceilf(sqrtf((end.x - start.x) * (end.x - start.x) + (end.y - start.y) * (end.y - start.y)) / kBrushPixelStep), 1); for(i = 0; i < count; ++i) { if(vertexCount == vertexMax) { vertexMax = 2 * vertexMax; vertexBuffer = realloc(vertexBuffer, vertexMax * 2 * sizeof(GLfloat)); } vertexBuffer[2 * vertexCount + 0] = start.x + (end.x - start.x) * ((GLfloat)i / (GLfloat)count); vertexBuffer[2 * vertexCount + 1] = start.y + (end.y - start.y) * ((GLfloat)i / (GLfloat)count); vertexCount += 1; } //Render the vertex array glVertexPointer(2, GL_FLOAT, 0, vertexBuffer); glDrawArrays(GL_POINTS, 0, vertexCount); //Display the buffer [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } (This function is based on the function of the same name from the GLPaint sample application.) For the life of me, I can not figure out why this causes the screen to flash. The line is drawn properly (both in the Simulator and in the iPod). But, the flash makes it unusable. Anyone have ideas on how to prevent the "flash"?

• asp.net mvc, IIS 6 vs IIS7.5, and integrated windows authentication causing javascript errors?

  - by chris

  This is a very strange one. I have an asp.net MVC 1 app. Under IIS6, with no anon access - only integrated windows auth - every thing works fine. I have the following on most of my Foo pages: <% using (Html.BeginForm()) { %> Show All: <%= Html.CheckBox("showAll", new { onClick = "$(this).parent('form:first').submit();" })%> <% } %> Clicking on the checkbox causes a post, the page is reloaded, everything is good. When I look at the access logs, that's what I see, with one oddity - the js library is requested during the page first request, but not for any subsequent page requests. Log looks like: GET / 401 GET / 200 GET /Content/Site.css 304 GET /Scripts/jquery-1.3.2.min.js 401 GET /Scripts/jquery-ui-1.7.2.custom.min.js 401 GET /Scripts/jquery.tablesorter.min.js 401 GET /Scripts/jquery-1.3.2.min.js 304 GET /Scripts/jquery-ui-1.7.2.custom.min.js 304 GET /Scripts/jquery.tablesorter.min.js 304 GET /Content/Images/logo.jpg 401 GET /Content/Images/logo.jpg 304 GET /Foo 401 GET /Foo 200 POST /Foo/Delete 302 GET /Foo/List 200 POST /Foo/List 200 This corresponds to home page, click on "Foo", delete a record, click a checkbox (which causes the 2nd POST). Under IIS7.5, it sometimes fails - the click on the check box doesn't cause a postback, but there are no obvious reasons why. I've noticed under IIS7.5 that every single page request re-issues the requests for the js libraries - the first one a 401, followed by either a 200 (OK) or 304 (not modified), as opposed to the above log extract where that only happened during the 1st request. Is there any way to eliminate the 401 requests? Could a timing issue have something to do with the click being ignored? Would increasing the number of concurrent connections help? Any other ideas? I'm at a bit of a loss to explain this.

• Entity Framework 4.0 Databinding with sorting not working

  - by Mike Gates

  I want to do something that I thought would be very simple. I want to bind a generated Entity Framework EntityCollection to a WPF DataGrid. I also want this grid to be sortable. I have tried all kinds of things to make this happen, including using a CollectionViewSource. However, nothing seems to work. Using a normal CollectionViewSource around the EntityCollection gives me: 'System.Windows.Data.BindingListCollectionView' view does not support sorting. Ok...strange. I would have thought this would work. Next on the CollectionViewSource, I try setting: CollectionViewType="ListCollectionView" Great, sorting now works. But wait, I can't add or remove entities using the grid now, presumably because ListCollectionView doesn't support this with an entity framework context. So, I guess I need to capture events coming out of the datagrid in order to add or remove entities manually from my context. Now I can't find an event to capture to detect an add...! Why is this so hard? This should be the standard "demo" case that Microsoft should have designed around. Any ideas?
