  • How to capture live camera frames in RGB with DirectShow

    - by Jonny Boy
    I'm implementing live video capture through DirectShow for live processing and display. (Augmented Reality app). I can access the pixels easily enough, but it seems I can't get the SampleGrabber to provide RGB data. The device (an iSight -- running VC++ Express in VMWare) only reports MEDIASUBTYPE_YUY2. After extensive Googling, I still can't figure out whether DirectShow is supposed to provide built-in color space conversion for this sort of thing. Some sites report that there is no YUV<-RGB conversion built in, others report that you just have to call SetMediaType on your ISampleGrabber with an RGB subtype. Any advice is greatly appreciated, I'm going nuts on this one. Code provided below. Please note that The code works, except that it doesn't provide RGB data I'm aware that I can implement my own conversion filter, but this is not feasible because I'd have to anticipate every possible device format, and this is a relatively small project // Playback IGraphBuilder *pGraphBuilder = NULL;

  • System.Runtime.InteropServices.COMException (0x80070008): Not enough storage is available to process

    - by Darryl Braaten
    I am trying to diagnose this exception. "System.Runtime.InteropServices.COMException (0x80070008): Not enough storage is available to process this command. (Exception from HRESULT: 0x80070008) at System.Runtime.Remoting.RemotingServices.AllocateUninitializedObject(RuntimeType objectType) at System.Runtime.Remoting.RemotingServices.AllocateUninitializedObject(Type objectType) at System.Runtime.Remoting.Activation.ActivationServices.CreateInstance(Type serverType) at System.Runtime.Remoting.Activation.ActivationServices.IsCurrentContextOK(Type serverType, Object[] props, Boolean bNewObj) at Oracle.DataAccess.Client.CThreadPool..ctor() at Oracle.DataAccess.Client.OracleCommand.set_CommandTimeout(Int32 value) ... It does not look like any of the normal types of "storage" have hit any limits. The application is using about 400MB of memory, 70 threads, 2000 handles and the hard drive has many GB free. The machine is running Windows 2003 Enterprise server with 16GB of RAM so memory shouldn't be an issue. The application is running as a windows service so there are no GDI objects being used. Running out of GDI handles is a common cause of this exception. Database connections, commands & readers are all all wrapped with using blocks so they should be getting cleaned up correctly.

  • 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?

  • solution for RPC_E_ATTEMPTED_MULTITHREAD error caused by SPRequestContext caching SPSites?

    - by kerray
    Hi, I'm developing a solution for SharePoint 2007, and I'm using SPSecurity.RunWithElevatedPrivileges a lot, passing in UserToken of the SystemAccount. After reading http://hristopavlov.wordpress.com/2009/01/19/understanding-sharepoint-sprequest/ I finally began to understand why I get these System.Runtime.InteropServices.COMException (0x80010102): Attempted to make calls on more than one thread in single threaded mode. (Exception from HRESULT: 0x80010102 (RPC_E_ATTEMPTED_MULTITHREAD)) errors, but there seems to be no solution - "known issue in the product" The article is more then a year old. I wasn't able to find anything more recent and helpful, but I was hoping maybe someone else has? My code goes like this SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite elevatedSite = new SPSite(web.Site.ID, web.Site.SystemAccount.UserToken)) { using (SPWeb elevatedWeb = elevatedSite.OpenWeb(web.ID)) { // some operations on lists and items obtained through elevatedWeb } } } The errors come up wherever such an elevated code is used, and more often when there are more users who use these functionalities, so I guess perhaps the elevated SPSite is getting cached and reused. Is there any way to solve this? If my understanding is correct, how to make Sharepoint forget about the cached SPSites, and use a fresh one instead? Thanks

  • Unable to regress web application from AJAX Control Toolkit 3.0 back to 1.0

    - by David Neale
    I was recently asked to stop using the Ajax Control Toolkit 3.0 in my application and need to go back to 1.0. Luckily I only have one calendar control which I don't believe will be affected by this. I have removed the reference to the 3.0 .dll and added a reference to the 1.0 .dll. These are the assemblies in web.config: <assemblies> <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/> <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/> <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/> <add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/> <add assembly="System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/></assemblies> and this also also there: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/> <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/> <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/> </dependentAssembly> </assemblyBinding> </runtime> I get a compile error of: Could not load file or assembly 'AjaxControlToolkit, Version=3.0.30930.28736, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies.

  • Installing into the GAC with WiX 3.0

    - by Jeff Yates
    I have a DLL that I would like to install into the Global Assembly Cache so that it can be referenced from multiple locations. I have a File declaration with the Assembly attribute set to ".net" but when the installation tries to install the DLL into the GAC, I get the following error (I have tided it up a bit to make it more readable): MSI (s) (58:38) [19:14:31:031]: Product: MyProductName 1.01 -- Error 1935. An error occurred during the installation of assembly  'Compass,   version="1.0.0.0",   culture="neutral",   publicKeyToken="392B26B760D48103",   processorArchitecture="MSIL"'. Please refer to Help and Support for more information. HRESULT: 0x80131043. assembly interface:       IAssemblyCacheItem, function:             Commit, component: {53AEE63B-F356-4D4F-8D61-EB0640A6E160} I have hunted around to find out what this means and the error relates to FUSION_E_UNEXPECTED_MODULE_FOUND. This link also includes this information: /// When installing multi-file assemblies into the GAC, the hash of each module is /// checked against the hash of that file stored in the manifest. If the /// hash of one of the files in the multi-file assembly does not match what is recorded /// in the manifest, FUSION_E_UNEXPECTED_MODULE_FOUND will be returned. /// The name of the error, and the text description of it, are somewhat confusing. /// The reason this error code is described this way is that the internally, /// Fusion/CLR implements installation of assemblies in the GAC, by installing /// multiple "streams" that are individually committed. /// Each stream has its hash computed, and all the hashes found /// are compared against the hashes in the manifest, at the end of the installation. /// Hence, a file hash mismatch appears as if an "unexpected" module was found. Unfortunately, this doesn't make much sense to me and I don't see how it relates to my assembly, which isn't fancy or complex from my perspective (it's just a regular .NET 3.5 class library and the current installation test is occurring on my development machine, which is a valid target environment for my project - 32-bit Windows XP SP3). Can anyone shed some light on why I might be getting this error and how I might hope to fix it?

  • Why doesn't TransactionScope work with Entity Framework?

    - by NotDan
    See the code below. If I initialize more than one entity context, then I get the following exception on the 2nd set of code only. If I comment out the second set it works. {"The underlying provider failed on Open."} Inner: {"Communication with the underlying transaction manager has failed."} Inner: {"Error HRESULT E_FAIL has been returned from a call to a COM component."} Note that this is a sample app and I know it doesn't make sense to create 2 contexts in a row. However, the production code does have reason to create multiple contexts in the same TransactionScope, and this cannot be changed. Edit Here is a previous question of me trying to set up MS-DTC. It seems to be enabled on both the server and the client. I'm not sure if it is set up correctly. Also note that one of the reasons I am trying to do this, is that existing code within the TransactionScope uses ADO.NET and Linq 2 Sql... I would like those to use the same transaction also. (That probably sounds crazy, but I need to make it work if possible). http://stackoverflow.com/questions/794364/how-do-i-use-transactionscope-in-c Solution Windows Firewall was blocking the connections to MS-DTC. using(TransactionScope ts = new System.Transactions.TransactionScope()) { using (DatabaseEntityModel o = new DatabaseEntityModel()) { var v = (from s in o.Advertiser select s).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> By commenting out this section, it works using (DatabaseEntityModel o = new DatabaseEntityModel()) { //Exception on this next line var v = (from s1 in o.Advertiser select s1).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> ts.Complete(); }

  • Windows 7 - Enable Network DTC Access

    - by Russ Clark
    I have a Visual Studio 2010 Windows Forms application in which I start a transaction using the TransactionScope class. I then Receive a message from a Sql Server Broker Services message queue, which works fine. I next try to call a stored procedure from the same database with a call to my data access layer which is a Visual Studio dataset (xsd file). When I make this second call to the database I get the following error message: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B). I've seen several posts on the web that talk about Enabling DTC access through dcomcnfg.exe, and allowing DTC to communicate through Windows Firewall. I've done those things, and am still having this problem. I know our remote database server is setup to Enable DTC access, because we are using similar transactions in other projects built with Visual Studio 2008 on Windows XP and Vista. I think there is something specific about Windows 7 and Visual Studio 2010 causing this problem, but haven't been able to find out what it is. Can anyone help with this problem?

  • Calling Matlab's MLApp.MLAppClass.FEval from F#

    - by Matthew
    Matlab provides a COM interface that supports remote execution of arbitrary functions (and code snippets). In particular, it has an Feval method that calls a given Matlab function. The third parameter to this method, pvarArgOut, has COM type VARIANT*, and appears in the Visual Studio F# editor as an argument of type: pvarArgOut: byref<obj> The following code calls interp1, which in Matlab returns a matrix (i.e. 2D double array) result, as is normal for most Matlab functions. let matlab = new MLApp.MLAppClass() let vector_to_array2d (v : vector) = Array2D.init v.Length 1 (fun i j -> v.[i]) let interp1 (xs : vector) (ys : vector) (xi : vector) = let yi : obj = new obj() matlab.Feval("interp1", 1, ref yi, vector_to_array2d xs, vector_to_array2d ys, vector_to_array2d xi) yi :?> float[,] This code compiles fine, but when calling interp1, I get a COM exception: A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll Additional information: Invalid callee.

  • Problem hosting WebBrowser control in an ATL app.

    - by Andrew Bucknell
    I have a legacy atl app that hosts a webbrowser control in an ATL window. I create an instance of the client to host the browser using the following sequence CComPtr<IOleObject> spOleObject; HRESULT hr = CoCreateInstance(CLSID_WebBrowser, NULL, CLSCTX_INPROC, ID_IOleObject,(void**)&spOleObject); spOleObject->SetClientSite(this); GetClientRect(&rcClient); hr = spOleObject->DoVerb(OLEIVERB_INPLACEACTIVATE, &msg, this, 0, m_hWnd, &rcClient); hr = AtlAdvise(m_spWebBrowser, GetUnknown(), DIID_DWebBrowserEvents2, &m_dwCookie); CComVariant navvar(navurl); m_spWebBrowser->Navigate2(&navvar, NULL, NULL, NULL, NULL); This sequence works fine to create the initial browse window. The call to navigate2 works and if I look at the window via spy++ I have Shell Embedding - Shell DocObject View - Internet Explorer_Server. When a popup occurs (detected through NewWindow3) I launch a new window and execute the same code sequence for the new window. In the popup window the navigate2 doesnt work, and when I look at this new window in spy++ I just have Shell Embedding. I get the same problem even if I instantiate the popup window on startup, so its not related to NewWindow3 at all - it seems the second instance of the web control isnt instantiating even though all the calls return S_OK. This sequence worked fine under IE7 but now I am using IE8 and the popup window isnt working. There is clearly something I am missing but I cant guess what it may be. Any suggestions would be incredibly helpful.

    I have the following code in an Nunit test ... string url = ""; url = @"http://localhost/ClientPortalDev/Account/LogOn"; ieStaticInstanceHelper = new IEStaticInstanceHelper(); ieStaticInstanceHelper.IE = new IE(url); ieStaticInstanceHelper.IE.TextField(Find.ById("UserName")).TypeText("abc"); ieStaticInstanceHelper.IE.TextField(Find.ById("Password")).TypeText("defg"); ieStaticInstanceHelper.IE.Button(Find.ById("submit")).Click(); ieStaticInstanceHelper.IE.Close(); On right-clicking the project in Dev10 and choosing [Test With][NUnit 2.5], this test code runs with no problems ( Iahve TestDriven installed ...) When opening the NUnit from C:\Program Files (x86)\NUnit 2.5.5\bin\net-2.0\nunit.exe" and then opening my test dll, the following text is reported in NUnit Errors and failures ... Elf.Uat.ClientPortalLoginFeature.LoginAsWellKnownUserShouldSucceed: System.Runtime.InteropServices.COMException : Error HRESULT E_FAIL has been returned from a call to a COM component. As an Aside ... Right-Clicking the source cs file in Dev10 and choosing Run Test, ... works as well. The above test is actually part of TechTalk.SpecFlow 1.3 step, I have NUnit 2.5.5.10112, installed, I have Watin 20.20 installed, I have ... & in my NUnit.exe.config and I have the following App.config for my test dll...

  • System.IO.FileLoadException

    - by Raj G
    Hi All, I have got this error when using Enterprise Library 3.1 May 2007 version. We are developing a product and have a common lib directory beneath the Subversion Trunk directory <\Trunk\Lib\ into which we put all the third party DLLs. Inside this we have Microsoft\EnterpriseLibrary\v3.1 in which we have copied all the dlls from \Program Files\Microsoft Enterprise Library May2007\bin. Everything was working properly until one of the developers installed the source code on this machine. There were some dlls copied at the end of the source code installation and once that was done, he is not able to run the project anymore. He always gets this error 'Microsoft.Practices.EnterpriseLibrary.Data, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)' What is the problem here? I thought that when the source code was installed it was just supposed to build everything and copy in the bin directory within the source code parent directory. Also we have copied the Dlls from Microsoft Enterprise Library May 2007\bin directory into our product development directory and references into our project with a copylocal flag set to true. Can anyone help me out here RK

  • Error editing a blob field in ArcGIS Engine

    - by Victor Grigoriu
    I have a GIS layer backed by a MSSQL db. The features on the layer have, say, one field of type esriFieldTypeString and one of type esriFieldTypeBlob. I can edit the string field just fine, but, when I try to edit a blob, StopEditOperation() throws a very generic exception (message: "Error HRESULT E_FAIL has been returned from a call to a COM component.", error code: -2147467259). I couldn't find anything related in the server log. Does anyone have any idea what's going on? IServerContext serverContext = GetServerContext(agsConn, serviceName); ILayer layer = GetILayer(layerName, serverContext); IWorkspace workspace = GetIWorkspace(layer); var feature = GetIFeature(objectId, workspace, layer); var workspaceEdit = (IWorkspaceEdit)workspace; workspaceEdit.StartEditing(false); workspaceEdit.StartEditOperation(); var index = feature.Fields.FindField(featureDetailName); IField field = feature.Fields.get_Field(index); byte[] byteArray = {1, 2, 3}; MemoryBlobStream blob = new MemoryBlobStream(); ((IMemoryBlobStreamVariant)blob).ImportFromVariant(byteArray); if (field.CheckValue(blob)) { feature.set_Value(index, blob); } feature.Store(); workspaceEdit.StopEditOperation(); workspaceEdit.StopEditing(true); serverContext.RemoveAll(); serverContext.ReleaseContext();

  • When programatically creating a new IIS web site, how can I add it to an existing application pool?

    - by Ian Robinson
    I have successfully automated the process of creating a new IIS website, however the code I've written doesn't care about application pools, it just gets added to DefaultAppPool. However I'd like to add this newly created site to an existing application pool. Here is the code I'm using to create the new website. var w3Svc = new DirectoryEntry(string.Format("IIS://{0}/w3svc", webserver)); var newsite = new object[] { serverComment, new object[] { serverBindings }, homeDirectory }; var websiteId = w3Svc.Invoke("CreateNewSite", newsite); site.Invoke("Start", null); site.CommitChanges(); <update Although this is not directly related to the question, here are some sample values being used above. This might help someone understand exactly what the code above is doing more easily. webServer: "localhost" serverComment: "testing.dev" serverBindings: ":80:testing.dev" homeDirectory: "c:\inetpub\wwwroot\testing\" </update If I know the name of the application pool that I'd like this web site to be in, how can I find it and add this site to it? <update 2 I've added the following based on Mark's answer below. var appPool = new DirectoryEntry(string.Format("IIS://{0}/w3svc/AppPools/{1}", webServer, appPoolName)); site.Properties["AppPoolId"].Value = appPool; I seem to have moved passed the "RPC" error message I was initially receiving. Now this is the error message I'm receiving: Error: System.Runtime.InteropServices.COMException (0x8000500C): Exception from HRESULT: 0x8000500C at System.DirectoryServices.Interop.UnsafeNativeMethods.IAds.PutEx(Int32 lnControlCode, String bstrName, Object vProp) at System.DirectoryServices.PropertyValueCollection.set_Value(Object value) at ProvisionIISWebsite.Query.CreateWebsite(String webServer, String serverComment, String serverBindings, String homeDirectory, String appPoolName) in C:\Users\irobinson\My Projects\ProvisionIISWebsite\Query.cs:line 104 at ProvisionIISWebsite.Query.Handle_GetData(EngineBase& caller, Boolean isSubQuery, String query, String filterField, String filterText, Debugger& debugWriter, Boolean isRendered, Int32 timeout, String customConnection) in C:\Users\irobinson\My Projects\ProvisionIISWebsite\Query.cs:line 36 </update 2

  • Excel Plug-In Assembly Loading Problem (Access Denied)

    - by PlagueEditor
    I am developing an Excel 2003 add-in using Visual Studio 2008. My add-in loads fine; however, it loads plug-ins from other C# DLL's. I would like this to be done dynamically at run time so referencing them during development is something I would rather not do. Anyways, anytime I try to load a DLL from the Excel add-in at start up, it throws a security exception. This particular example is HTML Agility Pack. It's not a plug-in but a plug-in's dependency. But nonetheless it won't even load: {System.IO.FileLoadException: Could not load file or assembly 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418) File name: 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' ---> System.Security.Policy.PolicyException: Execution permission cannot be acquired. at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Boolean checkExecutionPermission) at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Int32& securitySpecialFlags, Boolean checkExecutionPermission) at System.Reflection.Assembly.nLoadFile(String path, Evidence evidence) at System.Reflection.Assembly.LoadFile(String path) at Cjack.Druid.SourcePluginManager.LoadPlugin(String filePath) in C:\Documents and Settings\Annie Tormey\My Documents\Visual Studio 2008\Projects\DruidAddin2003\Druid\SourcePluginManager.cs:line 26 } This is extremely frustrating because it runs perfectly fine for Office 2010 and as a standalone application. Thank-you to anyone who can give me an answer as to why this is happening or a solution to fix it. Thank-you for your time.

  • Two different assembly versions "The located assembly's manifest definition does not match the assem

    - by snicker
    I have a project that I am working on that requires the use of the Mysql Connector for NHibernate, (Mysql.Data.dll). I also want to reference another project (Migrator.NET) in the same project. The problem is even though Migrator.NET is built with the reference to MySql.Data with specific version = false, it still tries to reference the older version of MySql.Data that the library was built with instead of just using the version that is there.. and I get the exception listed in the title: ---- System.IO.FileLoadException : Could not load file or assembly 'MySql.Data, Version=1.0.10.1, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) The version I am referencing in the main assembly is 6.1.3.0. How do I get the two assemblies to cooperate? Edit: For those of you specifying Assembly Binding Redirection, I have set this up: <?xml version="1.0" encoding="utf-8" ?> <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral"/> <bindingRedirect oldVersion="0.0.0.0-6.1.3.0" newVersion="6.1.3.0"/> </dependentAssembly> </assemblyBinding> </runtime> </configuration> I am referencing this the main assembly in another project and still getting the same errors. If my main assembly is copied local to be used in the other assembly, will it use the settings in app.config or does this information have to be included with every application or assembly that references my main assembly?

  • Cast exception when trying to create new Task Schedueler task.

    - by seaneshbaugh
    I'm attempting to create a new task in the Windows Task Scheduler in C#. What I've got so far is pretty much a copy and paste of http://bartdesmet.net/blogs/bart/archive/2008/02/23/calling-the-task-scheduler-in-windows-vista-and-windows-server-2008-from-managed-code.aspx Everything compiles just fine but come run time I get the following exception: Unable to cast COM object of type 'System.__ComObject' to interface type 'TaskScheduler.ITimeTrigger'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B45747E0-EBA7-4276-9F29-85C5BB300006}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Here's all the code so you can see what I'm doing here without following the above link. TaskSchedulerClass Scheduler = new TaskSchedulerClass(); Scheduler.Connect(null, null, null, null); ITaskDefinition Task = Scheduler.NewTask(0); Task.RegistrationInfo.Author = "Test Task"; Task.RegistrationInfo.Description = "Just testing this out."; ITimeTrigger Trigger = (ITimeTrigger)Task.Triggers.Create(_TASK_TRIGGER_TYPE2.TASK_TRIGGER_DAILY); Trigger.Id = "TestTrigger"; Trigger.StartBoundary = "2010-05-12T06:15:00"; IShowMessageAction Action = (IShowMessageAction)Task.Actions.Create(_TASK_ACTION_TYPE.TASK_ACTION_SHOW_MESSAGE); Action.Id = "TestAction"; Action.Title = "Test Task"; Action.MessageBody = "This is a test."; ITaskFolder Root = Scheduler.GetFolder("\\"); IRegisteredTask RegisteredTask = Root.RegisterTaskDefinition("Background Backup", Task, (int)_TASK_CREATION.TASK_CREATE_OR_UPDATE, null, null, _TASK_LOGON_TYPE.TASK_LOGON_INTERACTIVE_TOKEN, ""); The line that is throwing the exception is this one ITimeTrigger Trigger = (ITimeTrigger)Task.Triggers.Create(_TASK_TRIGGER_TYPE2.TASK_TRIGGER_DAILY); The exception message kinda makes sense to me, but I'm afraid I don't know enough about COM to really know where to begin with this. Also, I should add that I'm using VS 2010 and I had to set the project to either be for x86 or x64 CPU's instead of the usual "Any CPU" because it kept giving me a BadImageFormatException. I doubt that's related to my current problem, but just in case I thought I might as well mention it.

  • How can I test blades in MVC Turbine with Rhino Mocks?

    - by Brandon Linton
    I'm trying to set up blade unit tests in an MVC Turbine-derived site. The problem is that I can't seem to mock the IServiceLocator interface without hitting the following exception: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) at System.Reflection.Emit.TypeBuilder._TermCreateClass(Int32 handle, Module module) at System.Reflection.Emit.TypeBuilder.CreateTypeNoLock() at System.Reflection.Emit.TypeBuilder.CreateType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.InterfaceProxyWithTargetGenerator.GenerateCode(Type proxyTargetType, Type[] interfaces, ProxyGenerationOptions options) at Castle.DynamicProxy.DefaultProxyBuilder.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options, IInterceptor[] interceptors) at Rhino.Mocks.MockRepository.MockInterface(CreateMockState mockStateFactory, Type type, Type[] extras) at Rhino.Mocks.MockRepository.CreateMockObject(Type type, CreateMockState factory, Type[] extras, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.Stub(Type type, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.<>c__DisplayClass1`1.<GenerateStub>b__0(MockRepository repo) at Rhino.Mocks.MockRepository.CreateMockInReplay<T>(Func`2 createMock) at Rhino.Mocks.MockRepository.GenerateStub<T>(Object[] argumentsForConstructor) at XXX.BladeTest.SetUp() Everything I search for regarding this error leads me to 32-bit vs. 64-bit DLL compilation issues, but MVC Turbine uses the service locator facade everywhere and we haven't had any other issues, just with using Rhino Mocks to attempt mocking it. It blows up on the second line of this NUnit set up method: IRotorContext _context; IServiceLocator _locator; [SetUp] public void SetUp() { _context = MockRepository.GenerateStub<IRotorContext>(); _locator = MockRepository.GenerateStub<IServiceLocator>(); _context.Expect(x => x.ServiceLocator).Return(_locator); } Just a quick aside; I've tried implementing a fake implementing IServiceLocator, thinking that I could just keep track of calls to the type registration methods. This won't work in our setup, because we extend the service locator's interface in such a way that if the type isn't Unity-based, the registration logic is not invoked.

  • Do you have ideas for a workaround for this Known bug in Visual Studio 2010's addIn model ?

    - by Jesper
    When developing AddIns for Visual Studio 2010 the following line fails: CommandBarEvents handler = (EnvDTE.CommandBarEvents)m_VSStudio.DTE.Events.get_CommandBarEvents(popup); Update: Forgot to tell that m_VSStudio is of the type DTE2 Where popup is of the type CommandBarPopup (for the type CommandBarControl it works though) The line fails with this Exception: System.Runtime.InteropServices.COMException (0x80020003): Member not found. (Exception from HRESULT: 0x80020003 (DISP_E_MEMBERNOTFOUND)) The exact same line worked in Visual Studio 2008. The purpose of the line is to get a handler which handles clickevents, when one clicks the Popup. After som searching I found this link: http://connect.microsoft.com/VisualStudio/feedback/details/524335/events-get-commandbarevents-exception-on-submenus-reproducible-bug-addin Which basicly states that it is a known bug, which will not be fixed, because there is a workaround. But unfortunately it does not state the workaround :( I would be extremely pleased if anybody has a great idea for a workaround ? The reason why I want to listen to the click events is because I want to show or hide the submenuitems (CommandBarControl) given some condition, when one clicks a menu (CommandBarPopup). So a workaround that uses something else than the click event would also be appreciated.
