 - unrecognized attribute xmlns I get this error accessing a 2.0 site on a web server previously running .net v1.1. I've installed v2.0. I've run aspnet_regiis -i. I've changed the ASP.NET version on the ASP.NET tab in IIS. But it still uses the v1.1 framework. Any suggestions? Tag: 'System.InvalidOperationException' Tag: 120793

 - Diagnosing System.IO.IOException I have an application that generates and moves 1000s of small text files. Every so often for some unknow reason I start to get the following 2 exceptions: System.IO.IOException: Not enough quota is available to process this command. at System.IO.Directory.GetFiles(String path, String searchPattern) and (if the first exception does not happen we get a bit further and try to move the files we found) System.IO.IOException: Insufficient system resources exist to complete the requested service. at System.IO.File.Move(String sourceFileName, String destFileName) I can see no problems with available memory, the app does not use huge chunks of resources as far as I can tell from taskman and process explorer, restarting the application clears the problem. Load on the app does not seem to cause it as I can hit it VERY hard and it does not fail.. this leads me to think it is down to another application or the OS. Has anyone else seen this or got any good ideas on how to track the cause? Tag: 'System.InvalidOperationException' Tag: 120789

 - system.badimageformatexception returned from custom installer I have a web project that I have converted from VS 2003 to VS 2005. The installer is configured to use detect a newer version and if found to uninstall the old version before installing the new version. The installer in the new version VS 2005 contains custom actions that are compiled with VS 2005. For launch conditions, I have configured the .NET Framework to be at 2.0.50727 and Allow Later Version si set to True. When I run the installer I receive the system.badimageformatexception which references the dll that contains the custom installer code. If I uninstall the 2003 version of the software and then do an install of the 2005 version everything works fine. But if I have the 2003 version installed and then run the installer for the 2005 version I receive the error about the bad image. Is this a bug? Am I doing something wrong? Are there workarounds? Will my customers have to uninstall the old version manually before installing the new version? Thanks, Leslie Tag: 'System.InvalidOperationException' Tag: 120777

 - saving common settings/data without administrative privileges I am trying to find a way to save common data in my program that will not change from different users. I tried both HKEY_LOCAL_MACHINE and writting to an ini file and storing it in my Program directory. However, in order for this to work, all the users need administrative privileges. Is there a proper way to store common data that I am not aware of? For example, I have a test number that I need to increment. And this test number must not change when the user changes.

 - Windows Service project and how to debug Hi, I created a Windows Service project, the installers and the setup project for the service. Now I have the service installed but once I start it up, it's taking 100% CPU and not doing anything. I tried attaching the visual studio debugger to the win service process but it's not stopping at any breakpoints. Does anyone have any idea about why it's taking the 100% CPU. And how can I debug and see what's going on? Thanks very much in advance!! Agnes Tag: 'System.InvalidOperationException' Tag: 120759

 - HttpCFG DS Mapping not working I'm trying to configure DS Mapping with httpcfg. I have a test application using HttpListener which is listening on port 8001 ssl. To configure the ssl certificates I used httpcfg. This is my command: httpcfg set ssl -i 0.0.0.0:8001 -f 3 -c "MY" -h <Certificatehash> -f 3 : Should take care of mutual authentication and with DS Mapping. But it is not working. I know for sure the certificates are fine, and my AD mapping is ok, because if I test with IIS, it works perfect, and authenticates the client with the Windows user. But as soon as I move to my application and httpcfg, it validates the certificates, but it does not authenticate the client with a windows user. I'm using Thread.CurrentPrincipal.Identity.IsAuthenticated to see if it is working. http query ssl shows this: ------------------------------------------------------------------------ IP : 0.0.0.0:8001 Hash : 669b8ab4172fd790d8d5c9aca643f8fbd7 332b1 Guid : {00000000-0000-0000-0000-000000000000} CertStoreName : MY CertCheckMode : 0 RevocationFreshnessTime : 0 UrlRetrievalTimeout : 0 SslCtlIdentifier : (null) SslCtlStoreName : (null) Flags : 3 Can anyone help me??

 - XmlSerializer usage 1) I have an XSD that defines a document structure 2) I have a business object whose internal state can be represented by an XML document that is conformant to the XSD specification Many times, the first thought a lot of folks have is, "Silly, just run your XSD through xsd.exe and you can get a dataset or a class model!" That's not going to work for me, though. My business object contains a good bit of logic and the lightweight zero-method classes that are generated by xsd.exe are not appropriate for what I'm doing. So, I decided to take the approach of implementing the IXmlSerializable interface instead. Life is good. I'm curious, though, how folks insulate their business object from changes in the schema? This object's state is being persisted as an XML string. There will come a time when I have to change the XSD to encance the feature set. So, my class will have to be able to Deserialize its state from either of 2 (or more) different XSD Schemas because there may be older persisted versions (and yes, I want to validate the XML). How do people generally handle this scenario? (no...just not validating the XML is not an option) Here's my approach: If the Class is called Person, then The Class Person Implements the IXmlSerializable interface The Person class has a number of private nested classes (so they have access to the Person class's state fields). These are called DeSerializationFactory Version1Deserializer Version2Deserializer Version3Deserializer ... VersionNDeserializer Serializer When ReadXml is called on the Person Class, the NamespaceURI property is checked. Based on the value of that property a Version[1 2 or 3]Deserializer is created via the DeSerializationFactory. The resultant serializer deserializes the state and then life is good. When WriteXml is called, the default Serializer instance is created and the state is written as XML (always the latest version). This seems to be working for me, but I was curious how other folks mitigate this. Tag: 'System.InvalidOperationException' Tag: 120742

 - How To: Setup project Custom dialog boxes Hi In my setup project I need a custom dialog box containing a drop down list box. Since this is not avaialble from standard user interface dialog boxes that visual studio supplies, I am using Installer class. This installer class inturn displays the custom dialog box i need. but the problem is this custom dialog box is displayed as a popup window during installation. But I want this custom dialog box to be shown as one of the wizard pages during installation. Has any one done this before? I know some few setup programs that do this. However I am not sure that they used visual studio setup and deployment project to create their setup programs. Thanks Gancy Tag: 'System.InvalidOperationException' Tag: 120721

 - Drawstring inserts spurious linebreak after character #132 I am using DotNet v1.1.4322. This issue can be replicated with various text fonts - but is easiest to see using WingDings. 1) Create a string which includes character #132 2) Draw it to a Graphics object with DrawString S := #130+#131+#132+#133+#134+#135+#136+#137+#138+#139; F := System.Drawing.Font.Create('WingDings', 16); G.DrawString(S, F, Brushes.Black, 0, 0); The output always wraps immediately after character #132, regardless of font size, StringFormat settings, etc. Is this a bug in DrawString, or is it due to some other setting of which I am not aware? Does it happen in DotNet v2? Tag: 'System.InvalidOperationException' Tag: 120720

 - .Net x64 / x32 incompatibility "is ambiguous in the namespace" I ma trying to compile my XP x32 build after reboot into XPx64 as native x64 application. In VS2005 I changed my VB.net configuration to x64 and changed the reference path to point to c:\windows\microsoft.net\framework64 (before it was without the 64). Most things fell into place after these changes, but several classes are no longer available in the interllisense completion list and they are listed as errors as well. Even simple things such as Debug.Assert() are no longer available. Sample error: 'Debug' is ambiguous in the namespace 'System.Dosagnostics'. Do those classses really not exist as 64 bit version? What is the best way to resolve this? Thanks, Ingmar Tag: 'System.InvalidOperationException' Tag: 120710

 - Seemingly simple regex question I'm using the following regex expression where "searchword" is a string: string regrexstr = @"( |^)\b" + searchword + @"+( |\b)" My goal is to use this string to ultimately replace all occurances of searchword as long as: a) it has a preceeding space or it's the beginning of a line AND b) it is suffixed with a space or a newline character The problem right now is that using the above string and calling Regex.Replace also replaces the leading/trailing spaces. I want the spaces to count during the match, but be ignored during the replace. Is that easily do-able? I'm probably going about this the wrong way. In short, I want to do a word replacement throughout a large file. TIA! -sb Tag: 'System.InvalidOperationException' Tag: 120706

 - Wanted: .NET Infrastructure book Hi folks, I work in IT, but on the infrastructure/engineering side. At work I'm now being asked to design infrastructure solutions to support new .NET applications. Typically, this infrastructure must be highly available and support things like load balancing etc.... the only problem is I don't have a thorough understanding of how to accomplish this. Is the infrastructure tiered? How does the presentation layer talk to the middleware? These are the types of questions I have. I want to get a grounding how infrastructure wraps around the .NET framework and how enterprise solutions are designed.

 - PublicKey of System.Xml assembly I need to make some classes in my assembly internal. I am using XMLSerializer to serialize the objects of my classes. XMLSerializer cannot access my internal classes. So I am thinking that adding System.Xml as a friend would make my internal classes visible to XMLSerializer. Adding System.Xml as a friend requires public key of the System.Xml assembly specified. I can get the PublicKeyToken, but not the public key. I tried following code also but no luck, it just returns 16 bytes (0000000040000000). Assembly assembly = Assembly.GetAssembly( typeof(System.Xml.Serialization.XmlSerializer)); byte[] pubkey = assembly.GetName().GetPublicKey(); Any ideas to get the public key of System.Xml assembly, it doesn't have to be programatically.

 - WSS document event handler that will use System.web.mail sendmail I am not using vs studio 2.0 I have 1.1 I have a WSS document event handler that works on a document insert, I want to use system.web.mail to get to sendmail and put out an email. Document event handlers are written with C# class library which does not allow me to reference system.web.mail. I use use the interface with a web control and reference the web control from within the document event class but when I compile I get c:\Documents and Settings\cmello\My Documents\Visual Studio Projects\SISWorkflow\bin\Debug\SendMailCtrl.dll Referenced class 'SendMailCtrl.DocLibSendMail' has base class or interface 'System.Web.UI.WebControls.WebControl' defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web'. I am thinking that is because in the SendMailCtrl dll there is a method that uses SendMail and the reference to System.web.mail inside the web control project is the reason that I cannot create a new instance of the web control object in my C# document event library and call the method to send mail.

 - StatusStrip layout Greetings, We are using StatusStrip to present various status messages, progress bars, and so forth, throughout the user experience. We are finding, however, that the layout leaves something to be desired, or we do not have a good understanding of how layout is managed. In particular, how does one designate specified regions for one text or another or a progress bar? For example, without things hiding and moving around? Is there a way to do this, something like what taskbar does for us, or what one might find in Microsoft Word or Excel? Thanks in advance.

 - Setting StringBuilder.Length not behaving per documentation Perhaps this has been discussed elsewhere - if so, I couldn't find it. The StringBuilder.Length property is explicitly documented as padding the length with spaces if .Length is set to a value greater than the current length. I'm hoping to get this behavior. However, when I set .Length to something greater than the current length, the padding is done with null characters ('\0'), not spaces. Is this the actual intended behavior (and the docs are wrong) or a bug (and the docs are right)? Any help in this would be appreciated.

 - Serialization Files Compatibility I pciked up a project and am encountering several deficiencies on the architecture. My current concerns are the persisted data files that are written and read through dynamic reflection and Serialization/De-Serialization. The application has been going on for a while and is using .Net Framework 1.1. They intend to switch to .Net Framework 2.0. If data files are saved through an application saved on .Net 1.1 and later attempted to read through an application running on the .Net 2.0 Framework, will it work? Also, this is a number crunching application. There will be versions running on 32-bit machines and 64-bit machines. Can Serialized data files be shared between versions of the application running on the 2 platforms? -- Ed Reyes Tag: 'System.InvalidOperationException' Tag: 120685

In that assembly, I also have a Settings class that's XmlSerializable. <xmlSerializerSection type="MyApp.MyAppSettings, MyApp"> <MyAppSettings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">  </MyAppSettings > </xmlSerializerSection> Using June 2005 Enterprise Library's ConfigurationManager.WriteConfiguration, I save user changes to the settings. However, it serializes the settings with the fullname of the type: <xmlSerializerSection type="MyApp.MyAppSettings, MyApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1234567890ABCDEF"> <MyAppSettings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">  </MyAppSettings > </xmlSerializerSection> This is problematic when I roll out updates to the application. When I roll out version 1.0.1.0 of the application, ConfigurationManager.GetConfiguration() fails because the user's xml settings refer back to 1.0.0.0. If the xmlSerializerSection's type contains only the type name and assembly, everything works great (i.e., it loads the type from 1.0.1.0). Binding redirect from 1.0.0.0 to 1.0.1.0 doesn't seem to work. I have the following options: 1. Don't make the application strongnamed. 2. Keeps the settings class in a seperate assembly. I'm not crazy about either options. When serializing xml, is it possible not to save the type's fullname? thanks in advance. JT Tag: 'System.InvalidOperationException' Tag: 120653

 - .Net Equivalent to a VBS Script? Is there a way to build a .net file in C# which will JIT compile and execute when double-clicked (a la the old .vbs scripting approach)? This would just be a nice, convenient way for me to do some scripting where I don't want to have to build a whole project and application. Alex Tag: 'System.InvalidOperationException' Tag: 120647

 - Bogus "Cannot find the assembly" exception I have a very strange error; an ASP page invokes a method through .NET remoting which returns an exception as an output parameter. Unfortunately, no matter what exception the method returns, it appears as a different one ("Cannot find the assembly") to the ASP page. To clarify, I have an interface class called called IGetBoardInfo, which provides the interface for one method. I have a Windows service that exposes (through remoting) a class called GetBoardInfo, which implements the interface. It uses a class library called SubComponent, which can throw custom exceptions. Finally, an ASP webpage instantiates the GetBoardInfo class and calls its method. When it does, the GetBoardInfo class calls SubComponent, which throws a SubComponentException, which is returned via output parameter back to the ASP page. The problem is, which the ASP page tries to display the exception's message, this is the exception that appears: "Cannot find the assembly 'SubComponent', Version=1.0.1.2, Culture=neutral, PublicKeyToken=null." This is not the exception that was actually thrown. How is the real exception getting obscured, and this other exception being shown instead? Here is some much-simplified code that illustrates what I'm talking about: The interface class is specified like this: namespace TE.Service.IGetBoardInfo { [Serializable()] public struct BoardInfo { public long m_ID; public long m_siteNumber; } public interface IBoardInfo { BoardInfo[] GetBoardInfo(out Exception o_exception); } } The service itself is called GetBoardInfoSvc, and uses a C# class library called SubComponent. public class BoardInfoRpcServer : MarshalByRefObject, IBoardInfo { public BoardInfo[] GetBoardInfo(out Exception o_exception) { o_exception = null; BoardInfo[] info = null; try { // this line throws a SubComponentException info = SubComponentNamespace.SubComponent.GetBoards(); } catch(Exception e) { o_exception = e; info = null; } return info; } } The webpage has code that looks like this: Private Sub Page_Load(ByVal sender As System.Object, ByVal e As ystem.EventArgs) Handles MyBase.Load Dim url as String = "tcp://myComputerName:555/GetBoardInfo.rpc" Dim obj As IBoardInfo = Activator.GetObject(GetType(IBoardInfo), url) Dim exBoardInfo As Exception Dim strBoards() As BoardInfo = obj.GetBoardInfo(exBoardInfo) ' At this point, exBoardInfo is "Cannot find the assembly 'SubComponent'", ' which is not the exception that was originally thrown.

But I cannot figure = out what is the mistake.... Any help is really appreciated.
