• Using ReportViewer 9 control in VS 2010

  - by Fermin

  Hi, I am writing an ASP.NET app that uses a SQL Server 2005 with SSRS setup. I want to use the ReportViewer control but I get an error when using ReportViewer 10 because it needs SSRS 2008. How can I use ReportViewer 9 within my application. I've added a reference to the Microsoft.ReportViewer.WebForms.dll version 9 and removed the reference to version 10. My markup is as follows: <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %> <!-- standard markup --> <rsweb:ReportViewer ID="ReportViewer1" runat="server"></rsweb:ReportViewer> but when I try to run this I get the following error: CS0433: The type 'Microsoft.Reporting.WebForms.ReportViewer' exists in both 'c:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\10.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.WebForms.dll' and 'c:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\9.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.WebForms.dll' What have I missed!? Update: When trying to use the ReportViewer 10 I get the following error: "Remote report processing requires Microsoft SQL Server 2008 Reporting Services or later."

• Problem displaying custom error page in ASP.NET MVC 2

  - by robert_d

  This is customErrors section from my web.config file <customErrors mode="On"> <error statusCode="500" redirect="HTTP500.aspx" /> </customErrors> HTTP500.aspx is the same as standard /Views/Shared/Error.aspx page. When I get HTTP 500 error I see this page: Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed. Details: To enable the details of this specific error message to be viewable on the local server machine, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. But when I change the above customErrors section like this: <customErrors mode="On"> <error statusCode="500" redirect="HTTP500.htm" /> </customErrors> then HTTP500.htm page is displayed when HTTP 500 error occurs. Why HTTP500.aspx page isn't displayed?

• WCF service dataContractSerializer maxItemsInObjectGraph in web.config

  - by Dave

  I am having issues specifying the dataContractSerializer maxItemsInObjectGraph in host's web.config. <behaviors> <serviceBehaviors> <behavior name="beSetting"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> <dataContractSerializer maxItemsInObjectGraph="2147483646"/> </behavior> </serviceBehaviors> </behaviors> <services> <service name="MyNamespace.MyService" behaviorConfiguration="beSetting" > <endpoint address="http://localhost/myservice/" binding="webHttpBinding" bindingConfiguration="webHttpBinding1" contract="MyNamespace.IMyService" bindingNamespace="MyNamespace"> </endpoint> </service> </services> The above has no effect on my data pull. The server times out because of the large volume of data. I can however specify the max limit in code and that works [ServiceBehavior(MaxItemsInObjectGraph=2147483646, IncludeExceptionDetailInFaults = true)] public abstract class MyService : MyService { blah... } Does anyone know why I can't make this work through a web.config setting? I would like to keep in the web.config so it is easier for future updates.

• ASP.NET MVC tries to load older version of Owin assembly

  - by d_mcg

  As a bit of context, I'm developing an ASP.NET MVC 5 application that uses OAuth-based authentication via Microsoft's OWIN implementation, for Facebook and Google only at this stage. Currently (as of v3.0.0, git-commit 4932c2f), the FacebookAuthenticationOptions and GoogleOAuth2AuthenticationOptions don't provide any property to force Facebook nor Google respectively to reauthenticate users (via appending the appropriate query string parameters) when signing in. Initially, I set out to override the following classes: FacebookAuthenticationOptions GoogleOAuth2AuthenticationOptions FacebookAuthenticationHandler (specifically AuthenticateCoreAsync()) GoogleOAuth2AuthenticationHandler (specifically AuthenticateCoreAsync()) yet discovered that the ~AuthenticationHandler classes are marked as internal. So I pulled a copy of the source for the Katana project (http://katanaproject.codeplex.com/) and modified the source accordingly. After compiling, I found that there are several dependencies that needed updating in order to use these updated assemblies (Microsoft.Owin.Security.Facebook and Microsoft.Owin.Security.Google) in the MVC project: Microsoft.Owin Microsoft.Owin.Security Microsoft.Owin.Security.Cookies Microsoft.Owin.Security.OAuth Microsoft.Owin.Host.SystemWeb This was done by replacing the existing project references to the 3.0.0 versions and updating those in web.config. Good news: the project compiles successfully. In debugging, I received an exception on startup: An exception of type 'System.IO.FileLoadException' occurred in [MVC web assembly].dll but was not handled in user code Additional information: Could not load file or assembly 'Microsoft.Owin.Security, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) The underlying exception indicated that Microsoft.AspNet.Identity.Owin was trying to load v2.1.0 of Microsoft.Owin.Security when calling app.UseExternalSignInCookie() from Startup.ConfigureAuth(IAppBuilder app) in Startup.Auth.cs. Unfortunately that assembly (and its other dependency, Microsoft.AspNet.Identity.Owin) aren't part of the Project Katana solution, and I can't find any accessible repository for these assemblies online. Are the Microsoft.AspNet.Identity assemblies open source, like the Katana project? Is there a way to fool those assemblies to use the referenced v3.0.0 assemblies instead of v2.1.0? The /bin folder contains the 3.0.0 versions of the Owin assemblies. I've upgraded the NuGet packages for Microsoft.AspNet.Identity.Owin, and this is still an issue. Any ideas on how to resolve this issue?

• c# WinForms ReportViewer Performance issue using RefreshReport() and ServerReport.SetParameters()

  - by mdk

  Hi All, Currently I am writing a c# client application that uses the WinForms ReportViewer Control to display reports from a remote server. I am having performance troubles with the ReportViewer Control, to be specific with the 2 methods reportViewer.ServerReport.SetParameters() and reportViewer.RefreshReport() – they both take a really long time to complete and not just on the very first call, but on each subsequent call as well. SetParameters() takes 20 to 40 seconds (they vary greatly in time, some execute event okay fast) and RefreshReport() is a bit faster but still takes ages. I don’t think the server is the culprit, as the same report viewed using the browser renders pretty fast, about a second tops. The report in question doesn't matter as well. When I break into the process and take a look at the call stack, I see a call to Socket.DoConnect. So I thought that’s a good reason to start using fiddler and I installed it, disabled caching and fired up the app again to see which call takes that long to connect, but the performance issue was gone. By using a proxy I am having the same performance as the webbrowser. FYI: I am using NTLM authentication in the following way: reportViewer.ServerReport.ReportServerCredentials.NetworkCredentials = new NetworkCredentials() { Username = ... } I don’t have a strong webbackground, so I guess my question is: What should this tell me / What should I be looking into? (Btw: Adding fiddler to my installation package is not the solution I am looking for :)) I am grateful for any pointers. Take care, -Martin

• C#, Powershell - Microsoft.Exchange.Management.PowerShell.Admin

  - by Svein Erik

  I'm having troubles using the Microsoft.Exchange.Management.PowerShell.Admin on a server. The server is not the one running Exchange 2007, it's a remote server (in the same zone). I can't figure out how to add the Snapin for Powershell - Microsoft.Exchange.Management.PowerShell.Admin. Is it possible to just get the dll file from the Exchange 2007 server, and copy it to the server where my code is running? Can someone please explain what I need to do to get my code running? The exception that i'm getting now is: "No Windows PowerShell Snap-ins are available for version 1". This is the code that generates the error: public void CreateMailBox(User user) { //Create a runspace for your cmdlets to run and include the Exchange Management SnapIn... RunspaceConfiguration runspaceConf = RunspaceConfiguration.Create(); PSSnapInException PSException = null; PSSnapInInfo info = runspaceConf.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out PSException); Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConf); runspace.Open(); Pipeline pipeline = runspace.CreatePipeline(); Command command = new Command("New-Mailbox"); command.Parameters.Add("Name", user.UserName); .... The error is coming on the line with PSSnapInfo info = runspaceConf..... I'm using .NET 3.5

• ASP.NET websites under IIS 7.5 (Windows 7) running extremely slow

  - by emzero

  I've just installed Windows 7 x64 Ultimate on my desktop PC. I installed IIS, Visual Studio 2008, registered ASP.NET, etc. I have this ASP.NET 3.5 website I'm working on running EXTREMELY slow on this new IIS. On STA and PROD servers (Windows 2003 Server) and on my old XP/IIS 5.1 everything runs smoothly. A page which usually takes 1-2 seconds to load is taking 8 seconds!!! I saw this post on IIS forum. It says something about Vista/7 not pooling connections (just to let you know, the website is running locally but it's connecting to a SQL Server 2005 hosted on a remote server). It seems that it takes a while to "start loading" the page... I mean, I click refresh and it stays for several seconds "Waiting for localhost"... Then when it gets response it loads the whole page normally... I don't have a clue how to force Win7/IIS7.5 to pool database connections. EDIT: I've created a new empty ASP.NET web application to see if the problems happens too. The answer is no, it responds fast as it should with an empty default page. Maybe is something related to the DB connection. I will do a further test. It should be a way to fix it... EDIT 2: Debugging the app I noticed that the delay occurs AFTER the execution of .NET code (Page_Load, etc)... so the delay seems to be somewhere when IIS serves the page to the browser.

• WCF tcp.net client/server connection failing "Stream Security is required"

  - by Tom W.

  I am trying to test a simple WCF tcp.net client/server app. The WCF service is being hosted on Windows 7 IIS. I have enabled TCP.net in IIS. I granted liberal security privileges to service app by configuring an app pool with admin rights and set the IIS service application to run in the context. I enabled tracing on the service app to troubleshoot. Whenever I run a simple method call against the service from the WCF client app, I get the following exception: "Stream Security is required at http://www.w3.org/2005/08/addressing/anonymous, but no security context was negotiated. This is likely caused by the remote endpoint missing a StreamSecurityBindingElement from its binding." Here is my client configuration: <bindings> <netTcpBinding> <binding name="InsecureTcp"> <security mode="None" /> </binding> </netTcpBinding> </bindings> Here is my service configuration: <bindings> <netTcpBinding> <binding name="InsecureTcp" > <security mode="None" /> </binding> </netTcpBinding> </bindings> <services> <service name="OrderService" behaviorConfiguration="debugServiceBehavior"> <endpoint address="" binding="netTcpBinding" bindingConfiguration="InsecureTcp" contract="ProtoBufWcfService.IOrder" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="debugServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors>

• Maven error: Unable to get resource / Server redirected too many times

  - by tewe

  Our proxy went down and I tried to update dependencies with maven while it was off. Since then I can't download anything with maven. I get this error for everything. I tried -U option, deleting my local repository and tried different maven version (2.0.9, 2.2.1) but it doesn't work. Any idea how to solve this?

• Select videos using UIImagePickerController in 2G/3G

  - by Raj

  Hi, I am facing a problem where-in I cannot select videos from the photo album in iPhone 2G/3G device. The default photos application does show videos and is capable of playing them, which in turn means that UIImagePickerController should clearly be capable of showing videos in photo album and selecting them. I have coded this to determine whether the device is capable of snapping a photo, recording video, selecting photos and selecting videos: // Check if camera and video recording are available: [self setCameraAvailable:NO]; [self setVideoRecordingAvailable:NO]; [self setPhotoSelectionAvailable:NO]; [self setVideoSelectionAvailable:NO]; // For live mode: NSArray *availableTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera]; NSLog(@"Available types for source as camera = %@", availableTypes); if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { if ([availableTypes containsObject:(NSString*)kUTTypeMovie]) [self setVideoRecordingAvailable:YES]; if ([availableTypes containsObject:(NSString*)kUTTypeImage]) [self setCameraAvailable:YES]; } // For photo library mode: availableTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; NSLog(@"Available types for source as photo library = %@", availableTypes); if ([availableTypes containsObject:(NSString*)kUTTypeImage]) [self setPhotoSelectionAvailable:YES]; if ([availableTypes containsObject:(NSString*)kUTTypeMovie]) [self setVideoSelectionAvailable:YES]; The resulting logs for 3G device is as follows: 2010-05-03 19:09:09.623 xyz [348:207] Available types for source as camera = ( "public.image" ) 2010-05-03 19:09:09.643 xyz [348:207] Available types for source as photo library = ( "public.image" ) As the logs state, for photo library the string equivalent of kUTTypeMovie is not available and hence the UIImagePickerController does not show up (or rather throws exception if we set the source types array which includes kUTTypeMovie) the movie files in photo library. I havent tested for 3GS, but I am sure that this problem does not exist in it with reference to other threads. I have built the app for both 3.0 (base SDK) and 3.1 but with the same results. This issue is already discussed in the thread: http://www.iphonedevsdk.com/forum/iphone-sdk-development/36197-uiimagepickercontroller-does-not-show-movies-albums.html But it does not seem to host a solution. Any solutions to this problem? Thanks and Regards, Raj Pawan

• EXT-js PropertyGrid best practices to achieve an update ?

  - by Tom

  Hello, I am using EXT-js for a project, usually everything is pretty straight forward with EXT-js, but with the propertyGrid, I am not sure. I'd like some advice about this piece of code. First the store to populate the property grid, on the load event: var configStore = new Ext.data.JsonStore({ // store config autoLoad:true, url: url.remote, baseParams : {xaction : 'read'}, storeId: 'configStore', // reader config idProperty: 'id_config', root: 'config', totalProperty: 'totalcount', fields: [{ name: 'id_config' }, { name: 'email_admin' } , { name: 'default_from_addr' } , { name: 'default_from_name' } , { name: 'default_smtp' } ],listeners: { load: { fn: function(store, records, options){ // get the property grid component var propGrid = Ext.getCmp('propGrid'); // make sure the property grid exists if (propGrid) { // populate the property grid with store data propGrid.setSource(store.getAt(0).data); } } } } }); here is the propertyGrid: var propsGrid = new Ext.grid.PropertyGrid({ renderTo: 'prop-grid', id: 'propGrid', width: 462, autoHeight: true, propertyNames: { tested: 'QA', borderWidth: 'Border Width' }, viewConfig : { forceFit: true, scrollOffset: 2 // the grid will never have scrollbars } }); So far so good, but with the next button, I'll trigger an old school update, and my question : Is that the proper way to update this component ? Or is it better to user an editor ? or something else... for regular grid I use the store methods to do the update, delete,etc... The examples are really scarce on this one! Even in books about ext-js! new Ext.Button({ renderTo: 'button-container', text: 'Update', handler: function(){ var grid = Ext.getCmp("propGrid"); var source = grid.getSource(); var jsonDataStr = null; jsonDataStr = Ext.encode(source); var requestCg = { url : url.update, method : 'post', params : { config : jsonDataStr , xaction : 'update' }, timeout : 120000, callback : function(options, success, response) { alert(success + "\t" + response); } }; Ext.Ajax.request(requestCg); } }); and thanks for reading.

• Adding array of images to Firebase using AngularFire

  - by user2833143

  I'm trying to allow users to upload images and then store the images, base64 encoded, in firebase. I'm trying to make my firebase structured as follows: |--Feed |----Feed Item |------username |------epic |---------name,etc. |------images |---------image1, image 2, etc. However, I can't get the remote data in firebase to mirror the local data in the client. When I print the array of images to the console in the client, it shows that the uploaded images have been added to the array of images...but these images never make it to firebase. I've tried doing this multiple ways to no avail. I tried using implicit syncing, explicit syncing, and a mixture of both. I can;t for the life of me figure out why this isn;t working and I'm getting pretty frustrated. Here's my code: $scope.complete = function(epicName){ for (var i = 0; i < $scope.activeEpics.length; i++){ if($scope.activeEpics[i].id === epicName){ var epicToAdd = $scope.activeEpics[i]; } } var epicToAddToFeed = {epic: epicToAdd, username: $scope.currUser.username, userImage: $scope.currUser.image, props:0, images:['empty']}; //connect to feed data var feedUrl = "https://epicly.firebaseio.com/feed"; $scope.feed = angularFireCollection(new Firebase(feedUrl)); //add epic var added = $scope.feed.add(epicToAddToFeed).name(); //connect to added epic in firebase var addedUrl = "https://epicly.firebaseio.com/feed/" + added; var addedRef = new Firebase(addedUrl); angularFire(addedRef, $scope, 'added').then(function(){ // for each image uploaded, add image to the added epic's array of images for (var i = 0, f; f = $scope.files[i]; i++) { var reader = new FileReader(); reader.onload = (function(theFile) { return function(e) { var filePayload = e.target.result; $scope.added.images.push(filePayload); }; })(f); reader.readAsDataURL(f); } }); } EDIT: Figured it out, had to connect to "https://epicly.firebaseio.com/feed/" + added + "/images"

• System.Net.WebClient doesn't work with Windows Authentication

  I am trying to use System.Net.WebClient in a WinForms application to upload a file to an IIS6 server which has Windows Authentication as it only 'Authentication' method. WebClient myWebClient = new WebClient(); myWebClient.Credentials = new System.Net.NetworkCredential(@"boxname\peter", "mypassword"); byte[] responseArray = myWebClient.UploadFile("http://localhost/upload.aspx", fileName); I get a 'The remote server returned an error: (401) Unauthorized', actually it is a 401.2 Both client and IIS are on the same Windows Server 2003 Dev machine. When I try to open the page in Firefox and enter the same correct credentials as in the code, the page comes up. However when using IE8, I get the same 401.2 error. Tried Chrome and Opera and they both work. I have 'Enable Integrated Windows Authentication' enabled in the IE Internet options. The Security Event Log has a Failure Audit: Logon Failure: Reason: An error occurred during logon User Name: peter Domain: boxname Logon Type: 3 Logon Process: ÈùÄ Authentication Package: NTLM Workstation Name: boxname Status code: 0xC000006D Substatus code: 0x0 Caller User Name: - Caller Domain: - Caller Logon ID: - Caller Process ID: - Transited Services: - Source Network Address: 127.0.0.1 Source Port: 1476 I used Process Monitor and Fiddler to investigate but to no avail. Why would this work for 3rd party browsers but not with IE or System.Net.WebClient?

• Running PowerShell from MSdeploy runcommand does not exit

  - by Peter Moberg

  Im am trying to get MSDeploy to execute a PowerShell script on a remote server. This is how i execute MSDeploy: msdeploy \ -verb:sync \ -source:runCommand='C:\temp\HelloWorld.bat', \ waitInterval=15000,waitAttempts=1 \ -dest:auto,computername=$WebDeployService$Credentials -verbose HelloWorld.bat contains: echo "Hello world!" powershell.exe C:\temp\WebDeploy\Package\HelloWorld.ps1 echo "Done" The HelloWorld.ps1 only contains: Write-Host "Hello world from PowerShell!" However, it seems like PowerShell never terminates. This is the output from running the msdeploy: Verbose: Performing synchronization pass #1. Verbose: Source runCommand (C:\temp\HelloWorld.bat) does not match destination (C:\temp\HelloWorld.bat) differing in attributes (isSource['True','False']). Update pending. Info: Updating runCommand (C:\temp\HelloWorld.bat). Info: Info: C:\temp>echo "Hello world!" "Hello world!" C:\temp\WebDeploy>powershell.exe C:\temp\HelloWorld.ps1 Info: Hello world from Powershell!

Error: The process 'C:\Windows\system32\cmd.exe' (command line '/c "C:\Users\peter\AppData\Local\Temp\gaskgh55.b2q.bat"' ) was terminated because it exceeded the wait time. Error count: 1. Anyone knows a solution?

• getting a job in game industry as a developer, just knowing a game engine

  - by numerical25

  I recently enrolled at a community college for game developement. But I am skeptical about the circulum. I have no experience in the gaming industry so I wouldnt be able to tell rather its a good investment or not. So I am asking you. I dont want to get too much into detail of all the classes I am taking so I will try to be brief. By the time I graduate, I should have a understanding of how a game engine works. I will be working with the unreal engine to develop a Multiplayer game from scratch. So in the process of my final project, I will learn how to work within the unreal engine, Learn python and learn how to use it's API to connect to a remote server and build game mechanics. Overall I will also recieve a associates degree in game development. I learn c++ but not c. The director said he was trying to implement c in the program as well. What I notice is I will not learn how to build a 3d game engine from scratch. They do not teach any AI. I will not learn how to work with the graphics card using a graphic's api such as DirectX or OpenGL. I know building a game engine from scratch is a little complex, but at the same time the track is requireing me to take some advances math courses such a calculus and geotomtry 1 and 2. I also got to take a physic class. I just think thats a little much for just learning how to use the unreal engine but not actually build one or try to learn the anatomy of a game engine. Is this good enough to possibly land my a job in the insdustry. If I left anything out or was not detail, please feel free to ask more questions. Thanks Guys!!

• Silverlight WCF serialization [DataContract(IsReference=true)] problem

  - by Ciaran

  Hi, I'm have a Silverlight 3 UI that access WCF services which in turn access respositories that use NHibernate. To overcome some NHibernate lazy loading issues with WCF I'm using my own DataContract surrogate as described here: http://timvasil.com/blog14/post/2008/02/WCF-serialization-with-NHibernate.aspx. In here I'm setting preserveObjectReferences = true My model contains cycles (i.e. Customer with Collection). When I retrieve an object from my service it works fine, however when I try and send that same object back to the wcf service I get the error: System.ServiceModel.CommunicationException was unhandled by user code Message=There was an error while trying to serialize parameter http://tempuri.org/:searchCriteria. The InnerException message was 'Object graph ...' contains cycles and cannot be serialized if references are not tracked. Consider using the DataContractAttribute with the IsReference property set to true.' So cyclical references are now a problem in Silverlight, so I try change my DataContract to be [DataContract(IsReference=true)] but now when I try to retrieve an object from my service I get the following exception: System.ServiceModel.CommunicationException was unhandled by user code Message=The remote server returned an error: NotFound. It shouldn't be this hard to do something so trivial...

• Instructions on using TortoiseGit to interact with an SVN repository?

  - by markerikson

  I've been using TortoiseSVN on Windows for years with local filesystem repositories for my own projects. I'm planning to start collaborating with a friend on one of the projects, and will be shifting the repository to my own website. I've read a lot of "git beats SVN!" posts over the last couple years, and figured I ought to at least see what the fuss was about. Some research turned up the "git svn" command, and that TortoiseGit claims to have some level of git-svn support. I like the idea of keeping the SVN repository, and doing some local commits or branches with git before committing them to the repository. The "shelve" command also sounds useful. Unfortunately, while there's a number of CLI git-svn tutorials, there's nothing for TortoiseGit (which admittedly seems to be still in early development). As a result, I'm having problems trying to figure out what workflow I need to get these pieces to cooperate. I have an SVN repository in D:\Projects\repositories\MyProject. I created D:\Projects\temp\gittest, and tried to do a TortoiseGit "Git Clone" of the repository. From there, I've had issues trying to indicate the location of the trunk/branches/tags folders (which are just the standard layout in my repository). I was only able to get useful results when I left those unchecked. When I did seem to get the git repository started correctly, I was able to make some changes and do a couple git commits, but then had problems doing an SVN DCommit. So, I'm hoping someone out there can provide a reasonably detailed set of instructions on how to correctly use TortoiseGit with an existing SVN repository (with the repository on either the local filesystem or on a remote server). No "don't use SVN!" responses, please - I'm interested in learning how to get these two pieces to work together. If you feel TortoiseGit's SVN support isn't mature enough to make this work, that would also be useful information. Thanks!

• Spring security custom ldap authentication provider

  - by wuntee

  I currently have my ldap authentication context set up like this: <ldap-server url="ldap://host/dn" manager-dn="cn=someuser" manager-password="somepass" /> <authentication-manager> <ldap-authentication-provider user-search-filter="(samaccountname={0})"/> </authentication-manager> Now, I need to be able to set up a custom authorities mapper (it uses a different ldap server) - so I am assuming I need to set up my ldap-server similar to (http://static.springsource.org/spring-security/site/docs/2.0.x/reference/ldap.html): <bean id="ldapAuthProvider" class="org.springframework.security.providers.ldap.LdapAuthenticationProvider"> <constructor-arg> <bean class="org.springframework.security.providers.ldap.authenticator.BindAuthenticator"> <constructor-arg ref="contextSource"/> <property name="userDnPatterns"> <list><value>uid={0},ou=people</value></list> </property> </bean> </constructor-arg> <constructor-arg> <bean class="org.springframework.security.ldap.populator.DefaultLdapAuthoritiesPopulator"> <constructor-arg ref="contextSource"/> <constructor-arg value="ou=groups"/> <property name="groupRoleAttribute" value="ou"/> </bean> </constructor-arg> </bean> But, how do I reference that 'ldapAuthProvider' to the ldap-server in the security context? I am also using spring-security 3, so '' does not exist...

• Silverlight WCF netTcpBinding problem

  - by JontyMC

  Trying to call a WCF with a netTcpBinding via Silverlight, I am getting the error: "TCP error code 10013: An attempt was made to access a socket in a way forbidden by its access permissions.. This could be due to attempting to access a service in a cross-domain way while the service is not configured for cross-domain access. You may need to contact the owner of the service to expose a sockets cross-domain policy over HTTP and host the service in the allowed sockets port range 4502-4534." My WCF service is hosted in IIS7, bound to: http://localhost.myserivce.com on port 80 and net.tcp on port 4502 I can see http://localhost.myserivce.com/myservice.svc if I browse to it (my hosts file is pointing this domain to localhost). I can also see http://localhost.myserivce.com/clientaccesspolicy.xml: <?xml version="1.0" encoding="utf-8"?> <access-policy> <cross-domain-access> <policy> <allow-from http-request-headers="*"> <domain uri="*" /> </allow-from> <grant-to> <socket-resource port="4502-4534" protocol="tcp" /> </grant-to> </policy> </cross-domain-access> </access-policy> What am I doing wrong?

• Sending email through proxy using gmail smtp

  - by baron

  Hello everyone, Trying to send some email in my C# app. I am behind a proxy - which is no doubt why the code isn't working. This is what I have so far: App.Config: <system.net> <defaultProxy enabled="false"> <proxy proxyaddress="xxx.xxx.xxx.xxx"/> </defaultProxy> <mailSettings> <smtp deliveryMethod="Network"> <network host="smtp.gmail.com" port="587"/> </smtp> </mailSettings> </system.net> Code: var username = "..."; var password = "..."; var fromEmail = "..."; var toEmail = "..."; var body = "Test email body"; var subject = "Test Subject Email"; var client = new SmtpClient("smtp.gmail.com", 587) { Credentials = new NetworkCredential(username, password), EnableSsl = true }; try { client.Send(fromEmail, toEmail, subject, body); } catch (Exception e) { MessageBox.Show(e.Message); } Everytime I get System.Net.WebException: The remote name could not be resolved: 'smtp.gmail.com' Where/how do I start to debug?
