    - serializing IMethodCallMessage with SoapFormatter returns method not supported exception Hello: I am trying to soap-serialize an IMethodCallMessage intercepted with a custom proxy to a request stream of a HttpWebRequest.

    - Application Control for the #1: i had used System.Management object to list out the local installed application (i tried locally first) at Uninstall registry. for the #2: I searched that i can use Process.Start(application path); But the problem is that i do not know of the application path. I tried Windows' Run program. It can run a program just by entering the application name *.exe. If that is how i should run it, how can i relate the application name with the list of installed application No offence but Im reluctant to use fully wmi for remote connection, cause it needs admin authentication. And it is really not user friendly to ask user to enter authentication for each execution of program remotely. Or even put is at a admin setting. We would like to put minimum input for user as user might not really IT savvy. thanks in advance Tag: .NET Framework Networking and Communication what is networking in .NET .NET Development

    - FAXCOMEXLib API and Faxing PDFs with Reader 8.0 Installed Adobe seems to have changed their command line interface between Reader 7.0 and 8.0. Faxing a PDF via the MS Fax API works correctly with Reader 6 or 7 installed. However, after installing Reader 8, the PDF is sent to the user's default printer, regardless of the fax device you try to point to. I have manually tested the command line interface with Reader 7 and Reader 8 to confirm that the same call that works with 7 does not work with 8. I don't know who should be addressing this problem, Microsoft or Adobe. Any thoughts Tag: .NET Framework Networking and Communication what is networking in .NET .NET Development

    - How to set a Property ReadOnly dynamically based on another property value. Hi, I am sorry if I am not able to explain my requirement in the Subject. What I want is, I have a class with two Properties like HasSubMenu, and SubMenu Collection, object of this class is bound to property grid. The class i sgiven below. Code Snippet class Menu { private bool m_HasSubMenu; private List<Menu> m_SubMenu; [Browsable(true)] public bool HasSubMenu { get { return m_HasSubMenu; } set { m_HasSubMenu = value; } } [Browsable(true)] [ReadOnly(true)] public List<Menu> SubMenu { get { return m_SubMenu; } set { m_SubMenu = value; } } } This object of this class (initially with HasSubMenu false and an empty SubMenu Collection) is bound to a property grid. Now that I have a ReadOnlyAttribute set for SubMenu property this collection is read only and user can't edit in the property grid. But what I want is if the user changes the HasSubMenu property to true I want this collection to be editable (I mean somehow I want to make this ReadOnly attribute of SubMenu property false.) I am not able to figure out how should I do this.

    - Why ReaderWriterLock not release writer lock if inclusive read lock inside writer Lock was Hi Roman Uvarov, I wrote the program just like you have described, but I didn't encounter the problem as yours. And I don't understand why you call the LockReader() in LockWriter(). You have apply a writer lock on the object, why did you continue applying reader lock on it in the same thread And ReaderWriterLock class that encapsulates these rules: When one thread is writing to the data, no other thread can write to the data. When one thread is writing to the data, no other thread can read from the data. When one thread is reading from the data, no other thread can write to the data. When one thread is reading from the data, other threads can also read from the data. Hope this can help you. Thanks!

The application was working just fine, until the administrator uninstalled IIS, then we started experiencing the timeout exception. On my development machine XP Pro, I shutdown the SMTP service, and it does still work as you described. So I need to figure out what else could be causing the issue. Any ideas would be helpful.

    - Avoid serializing base class members As an alternative to the XmlSerialzier you can use the DataContractSerializer in .NET 3.0. The DataContractSerializer uses an explicit programming model, where you specfiy using the DataContractMemberAttribute which properties you want to serialize. All other properties are ignored. http://msdn2.microsoft.com/en-us/library/ms731072.aspx This serializer is used with the Windows Communication Foundation, which is the future platform for creating distributed systems and web services using .NET. http://msdn2.microsoft.com/en-us/library/ms735119.aspx Daniel Roth Daniel Roth Tag: .NET Framework Networking and Communication what is networking in .NET .NET Development

    - XmlSerialization attributes: difference between [XmlElement(...)] and [XmlElementAttribute(...)] While familiarizing myself with XML Serialization and controlling serialization using attributes, I've become confused whether there is a different between the use of "XmlElement" or "XmlElementAttribute" in actually writing the attribute in a class declaration, and in general for any serialization attribute. For example, consider the following class: public class Test { public: // public, parameterless constructor req'd for serialization Test(void) {} public: [XmlElement("Member1")] int m_Member1; [XmlElementAttribute("Member2")] int m_Member2; } Even MSDN doesn't seem quite clear on which to use. From the code I've seen, it sounds like XmlElementAttribute is the object in the .NET framework that handles this, but I am to use "XmlElement" while actualing writing the attribute. In contrast, I have seen other code that appends the "Attribute" part of the object name. What is the difference, and which is correct Anjo Tag: .NET Framework Networking and Communication what is networking in .NET .NET Development

    - define a new querydef in an access db using asp.net My scenario is this: I have inherited a large access database, critical to a website. I need to do some work on the site which requires that I modify a number of tables and create a few ne querydef so support the work. The obvious soluition is to ftp the db locally, modify the file and upload it. But If possible I do not want to do this. I don't want to lose data and I don't want to take the db offline. So what I would like to do is create an aspx page which I can use to do operations like creae new querydefs. How can I connect to an access db to do these kind of operations As far as I can tell, the regular OleDbConn does not allow me to do these operations - rather I need to use the access object model. I suspect there must be some utility out there on the internet to do this kind of thing (a bit like phpmyadmin).

    - The located assembly's manifest definition does not match the assembly reference. Oh yuck, the forms are in the same app. The CLR won't let you load two different versions of an assembly. The only possible approach is isolating the forms in their own assembly and load them into a separate AppDomain. I'm not sure if that is actually possible with the Form type. Perhaps if they run on their own thread. That's truly ugly too. Tag: .NET Framework Networking and Communication what is networking in .NET .NET Development

    - "Deserializing" XmlNode.OuterXml to object, then back to XmlNode questions Ah, I'm extremely sorry, I forgot to mention that if I do strip off the xmlns attribute as you describe above, the element is indeed imported into the original document, but it loses its namespace and cannot be found in the default namespace upon further search using xpath/SelectSingleNode(). If I run XmlDocument.Validate(), I get a schema exception saying that the element wasn't expected in the default namespace. This appears to me to be some lame problem with the XmlNode in memory, because if I close and reopen the application (or load a new XmlDocument with old one's xml string contents), the imported element works perfectly. In summary, I did not intend to mean only to imply that I *can't* remove the explicit namespace declaration (that is done quite easily), but that when I do, the importeded XmlNode behaves very badly in the original XmlDocument.

    - ILMerge: Problem with references Hi, I'm trying to use ILMerge to create components for the Umbraco web framework. I thought it would be nice is I only had to distribute one dll with my component. The setup I'm using is ( a bit simplified): MyComponent.csproj (Visual Studio web project) .... --References ----umbraco.dll (local reference, Copy Local == false) ----SomeComponent.dll (local reference, Copy Local == true) ----System.Web (GAC reference) .... The reason that I have Copy Local == false on the umbraco.dll is that this dll is part of the solution that my component must be deployed to. The SomeComponent.dll is a component used by my UserControls in my project and this is the dll I would like to merge with MyComponent.dll However if I execute: "ilmerge.exe /out:MyComponent.dll SomeComponent.dll" i get an error message saying: "Unresolved assembly reference not allowed: umbraco" I can however not just include the umbraco.dll since this would result in the classes within the umbraco.dll being defined twice when I deploy the MyComponent.dll in the umbraco web application. So my question is there anyway to avoid this error message or is ILMerge an all or nothing solution Regards, Rasmus Oudal Edberg Tag: .NET Framework Networking and Communication what is networking in .NET .NET Development

    - Strange: calling EndInvoke from an AsyncCallback - why UnhandledException The problem you encounter here is that the CLR will rethrow the exception inside the callback when you call EndInvoke. But it does only check if you do call EndInvoke on the same thread the callback executes. Since you call EndInvoke ulitmately from an arbitrary thread the CLR thinks your callback did not handle the exception and wil rethrow the exception when your callback is left.

    - C# - MSMQ - HTTP Issues I know this is not really a 100% C# question, however I'm trying to utilize MSMQ via C# over HTTP... I'm finding that I cannot create or check for the existance of Queues utilizing the HTTP channel whether they are private or public. Example code: string url = "FormatName IRECT=HTTP://myserver/ MSMQ/myqueue"; MessageQueue.Exists(url); MessageQueue.Create(url); Note: the annoying emoticon above shows up because its really a : D w/ no space For both of those methods I get errors eluding to - cannot create / check existance with that path syntax. I've also seen this example - changing the : to an = after FormatName, that seems worse off though just plain saying its an invalid syntax altogether. string url = "FormatName=DIRECT=HTTP://myserver/ MSMQ/myqueue"; As far as I've read, you can create / check the existance of Queues via HTTP, however I cannot get any example to work... all of the documentation I've seen only uses the OS direct path to do so.... Anyone have any ideas I can however retreive messages from the Qeueue via HTTP w/ that url syntax, but... w/ the architecture I'm working on I'd like to check for its existance first from the client. At this point I'm considering doing so with a webservice call prior to connecting to the Queue.
