    - Retrieving data from a Windows Service Hi, I have a collection that resides in a windows service and I want to know is remoting the best way to access this data? The collection will change on an ongoing basis, but whenever I make a request to the windows service I want to be able to get back the latest elements in the collection. Should I use remoting an expose my object as a Singleton? Is there a better way to do this? Thank you. Greg Tag: Service running Infinitely Tag: 129395

    - deadlock on a single Select not in a transaction Hi, We have a web application developped in asp.net (I think it's not relevant, but well, it's so you know)... Yesterday, we received the following message "Transaction (Process ID 69) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. " The thing is, the query was a simple select with inner joins between 3 tables (like select fields from table1 inner join table2... inner join table3....). This command is not in a transaction, so the deadlock seems impossible. And moreover, the deadlock occurs on the DataReader.Read() not on the Command.ExecuteReader(...). Can someone explain why the deadlock can have occured and what could be the cause and solution to it? Can it be a bug in SQL Server or in the .net framework (I really doubt about it)? thanks ThunderMusic Tag: Service running Infinitely Tag: 129387

    - EventTraceLogListener and error? I started with the logging application block in the April 2007 Enterprise Library. Looking through the source it looks like when it comes to the event log they just inherit the EventTraceLogListener class. It seems to work. I look via the EventViewer and can see messages that are place there via my app. Is there a way to specify that the entry is an error? warning? Something other than "Information"? Thank you.

    - Subclassing question. Hello, I followed the MS instructions to subclass Windows using C#.net (http://support.microsoft.com/kb/815775) as the follows. I then opened several Excel files, and selected anyone of them as foreground window. I was expecting to see windows message, saying WM_ACTIVATE, or something like that, however, to my surprise, I saw NO windows message when I randomly selected those Excel windows, (although I could see other window messages, e.g., WM_GETTEXT). What was wrong here? I need to be able to tell which Excel window is the active one programmatically. Was this a right approach for this purpose? Any papers? Thanks a lot. -------------------- Add a new Class module that is named SubclassHWND.cs to the Visual C# .NET or Visual C# 2005 application. To do this, click Add Class on the Project menu. 2. In the Name text box, type SubclassHWND.cs, and then click Open. 3. Replace the SubclassHWND class code with the following code:public class SubclassHWND : NativeWindow { protected override void WndProc(ref Message m) { // Perform whatever custom processing you must have for this message System.Diagnostics.Debug.WriteLine(m.ToString()); // forward message to base WndProc base.WndProc(ref m); } } 4. To demonstrate its use, add the following code to the Load event of Form1:SubclassHWND s = new SubclassHWND(); s.AssignHandle(this.Handle); //Now s should be listening to the messages of the form.

    - On Adobe's Flash & Flex in ASP.NET I have been asked to create some simple animation using Adobe Flash player in ASP.NET(C#) web application. While I am fairly well versed with ASP.NET C#, I absolutely have NO IDEA about how to say "Hello World" in a Flash enabled web page rendered via ASP.NET. Can any one let me get started? --- By the way, there is a NEWS today about Adobe Flex 2, which I can not comprehend. There are getting started articles for PHP developers on Adobe's website but nothing for ASP.NET developers. http://news.com.com/Adobe+to+open-source+Flash+tool+Flex/2100-7344_3-6179305.html It will be nice to hear something from experienced people.

However, when i publish the application again after making some changes, i expect that the newer version should run when i click on the shortcut, which does not happen in my case. Can some one tell me if i am doing anything wrong. (On the publish page "Application should Check for updates" is ON).

    - Workflow - CallExternalMethod -Correlation value is already intial Repeating calls to a CallExternalMethodActivity in a while loop - InvalidOperationException - Correlation value is already initialized I have a workflow that needs to call out to an external event until the event responds with a result of true. Unfortunately, the second time I call the external event, I get the error that the Correlation value is already initialized. I've implemented this with a while loop that has the condition that the result is true or an elapsed time of one hour has occured. The first activity in the loop is to call the external activity. The second is to delay for five minutes. Pretty simple. I've included the full error message the XOML and the code behind below. Has anyone run into this situation? Is there a way around it?

    - why use .net? Hi there, We need to retrospectively justify our choice in using .NET framework for developing our site. Our techie isnt here so we cant run it past him. Can some kind, helpful person run their eye over it and tell me if I'm tellling porkies, or if there is anything I should add? Why should people choose .net (I think ours is 1.1) Thanks Gay ****************** We recognised that in order to meet our aims of producing a high quality and consistent website, we had to ensure that our system was fast, robust and able to deal with a high number of users. We chose .NET framework so that we could meet these needs now, but also so that we could best account for any future developments in a cost effective manner. This has proved the case, in that with our Stage 2 developments we will be implementing a forum system. Using .NET has meant that we can integrate new modules with ease. With .NET's cross-platform interconnectivity, we feel that we have chosen the best approach for future-proofing. Tag: Service running Infinitely Tag: 129346

    - Piped input contains Unicode preamble I'm an old dog and I like old tricks, so I write a lot of utilities that accept piped input. e.g. TYPE mydata.txt | MyApp or MyApp < mydata.txt or App1 | App2 Then read the input with System.Console.In What I found though is that if the input file contains a Unicode preamble (i.e. EF BB BF for UTF-8) the preamble appears in the data, which is inconvenient. I'm not real interested in _why_ this is the case, but I wonder what others do to resolve this. So far, because I'm only concerned with "ASCII" text, I simply ignore all characters above 7F, but I'd like a more elegant solution. One other thing I tried was rather than use System.Console.In I tried new System.IO.StreamReader ( System.Console.OpenStandardInput , true ) which worked some times, but other times was missing the beginning of the data (which I assume is due to buffering).

    - Custom app and Korean I have an application written in .NET, running under Windows XP SP2 and Windows Server 2003 with SQL Server 2000 as the backend. This app basically indexes documents to allow keyword searching. We now need to load and index Korean language documents, but I have absolutely no idea what would be necessary to accomplish this. First off, we do use a third party product to perform the indexing, and I know that it supports Unicode. Any pointers and assistance would be appreciated.

    - managed API equivilent to WNetAddConnection Hi, I'm wondering if there is a managed class/method that is equivilent to the WNetAddConnection API. I am writing an app that is required to connect to various network resources without knowing whether those resources are connected before hand. I also need the functionality of being able to provide profile/password information when attempting to access the network resources. So far I haven't found anything that will work, but if anyone knows a way, I would appreciate hearing about it. Thanks. Kristofor Tag: Service running Infinitely Tag: 129336

    - Network communication with Windows Services Hello, I am designing an system where Windows services (clients) are distributed across a company LAN. The clients are written in Win32 since not all network machines may not have .NET Framework installed. The clients connect to a central SQL database to report relavent status information from the network machines. There is a WinForms application that monitors and provides results of the distributes clients to an operator. The application also allows the operator to deploy the clients to the remote machines via Windows Networking APIs, or externally using Active Directory and a supplied Windows Installer Package that installs the Windows Service client out to the network. The target network(s) are Windows based using Active Directory. The client machines are Windows 98 and above....however, we may limit the requirements to only support Windows 2000 and above if necessary. I was hoping some of you can provide your opinions on the following questions: 1) Given the above design/architecture, do you think there are other or better methods for implementing the system? ie, any other technologies that would better suite the situation other than each client directly connecting to SQL Server... 2) Please comment on the idea of using a web service (installed on the database server) for clients to connect to provide status information? 3) Are there other or better technologies for distributing the Windows Service clients outside of the ones mentioned above? Note, this system will be used on a broad range of networks that may not have specific technologies in production. Thanks in advance for your input. Its always good to get other opinions.

But my problem is it starts utilizing 98 to 100% of the CPU. I needed to know is there any way where in i can control the amount of CPU utilization for my application and restrict it to use say some 60 -70% of the CPU. Actually when it starts utilizing 98 to 100% of the CPU, i get a feel that my system is hung-up, so i wanted to avoid this. Is there any other solution to this problem.

How does the database server "know" that there is a transaction scope in place? Finally in the example I notice that the Prepare is not called untill the scope ends. (scope.Complete()).

    - OrderedDictionary index order The OrderedDictionary method documentation says that the Add(key, value) method stores the entry into the OrderedDictionary collection with the lowest available index. This ensures that the oldest entry is at index 0. The Remarks section of the OrderedDictionary.Add Method says you can also use the System.Collections.Specialized.OrderedDictionary.Item(System.Object) property to add new elements by setting the value of a key that does not exist in the OrderedDictionary collection. The Remarks section of the OrderedDictionary.Item Property(Object) says that the 'myCollection["myNonexistentKey"] = myValue' syntax can also be used to add an entry. Is it safe to assume that the entry at index 0 is the oldest entry when entries were added using the indexer syntax? This is the behavior I observed experimentally. Wouldn't it be nice if a class's indexer functionality was documented in a consistent place? Thanks Mike Tag: Service running Infinitely Tag: 129305

    - ConfigurationManager <-> ConfigurationSettings Hi, at the moment I am about to move a WinForm application from .NET 1.x to .NET 2.0. The application is deployed using no-touch-deployment. The customer wants to keep this behaviour and so I cannot change it to click-once-deployment *sigh* However, the application requires full rights on the machine it is running on. The developer which started the project in .NET 1.x therefore implemented a little launcher application which raised a new AppDomain grating full rights. The launcher application is signed to get this working. The WinForm application now gets executed in this new AppDomain. This all worked fine in .NET 1.x when ConfigurationSettings.AppSettings have been used to gather information about the WebService location. Now I changed reading of configuration values to ConfigurationManager.AppSettings and implemented my own ConfigurationSection derived class (MyConfigSection) for reading the configuration values. Everything worked fine when running the application locally. But when I tried to run the application via NTD the WinForm application got loaded twice from the server. The first time when executing it in the new AppDomain (let's call it MyClient.exe). The second time when accessing configuration using ConfigurationManager (let's call it MyClient.EXE - notice the different writings of "exe") . This resulted in a InvalidCastException although the types seemed to be identical in name and version. But after some digging I saw that the configuration values are read via assembly MyForm.EXE and a cast is tried to the type in assembly MyForm.exe which of course cannot be done. When I don't use my configuration section and only use ConfigurationManager.AppSettings again everythings works as expected. Does somebody have any idea how to solve this?

    - Exception handling bug?: Control.Invoke() Hello all, I'm currently working on exception handling for a multithreaded component. It looks like I've ran into a framework bug when inner exceptions is concerned. The code: internal delegate void TcpipMethod(TcpipSocket socket); private TcpipMethod _internalReceive; private void CallbackReceive(IAsyncResult result) { TcpipCloseMode closeMode = TcpipCloseMode.None; TcpipSocket socket = result.AsyncState as TcpipSocket; try { .. .. if (_syncControl != null) _syncControl.Invoke(_internalReceive, new object[] { socket }); else InternalReceive(socket); } catch (ObjectDisposedException) { } catch (Exception exception) { if (!(exception is SocketException && ((SocketException)exception).ErrorCode == 10054)) { if (_syncControl != null) _syncControl.Invoke(_internalError, new object[] { socket, exception }); else InternalError(socket, exception); } } } private void InternalReceive(TcpipSocket socket) { try { DoReceive(new TcpipEventArgs<T>(socket)); } catch (Exception e) { throw new TcpipException("Exception in receive event.", e); } } The CallbackReceive method runs on its own asynchronous thread. The property _syncControl is filled with UI control. This would allow me to synchronize the read event (DoReceive) to the application main thread. This event is called through the method InternalReceive which is the actual method being synchronized. The event caller (DoReceive) is placed in a try..catch block to capture any exceptions that occur inside the user event. The reason for this approach is to make sure user exceptions do not break the component. ObjectDisposedException is one that could potentially break the component, as it is generated by the user, and not in response to attempting to use a closed socket inside the component. The try block then raises a new exception (TcpipException) which takes the caught exception as the inner exception parameter. One would expect this raised exception be propagated back to the callback method as the documentation for Control.Invoke() explains. However, in the catch block inside the callback method, the exception is NOT the newly raised exception TcpipException, but it is the inner exception itself! If inside the user event an ObjectDisposed exception would have been thrown, this would be the type of the caught exception in the callback try..catch block. When I re-raise the exception without specifying the inner exception, it works fine and the callback method will catch the re-raised exception. But as soon as an inner exception is specified, the re-raised exception gets ignored somehow where the inner exception takes its place? I am not sure if this intended behaviour, but to me this sure doesn't seem to be the intended way. I've searched for any information on this subject, but I haven't found any exceptional situations to this. Effectively, it appears I can not 'remap' exceptions thrown in Control.Invoke'd methods while this (in my eyes) expected behaviour is critical for the component to operate...

Is there any way? or should I go for a normal other than service?
Any recommendations are appreciated.
thanks

AFAIK, the only way to do what you want would be to use Windows Embedded
(XP) an build a system image that does not include the Control Panel and
other access to the Administrator Tools -- I suspect that there is no
practical way to do it otherwise.

I think there must be a way by which you can override your StopService
function(I don't know the signature of the function but I am talking about a
function which is called whenever somebody stops the service!!) and just
ignore the stop command.
