    - serialization bug Hi, Could someone please confirm the following? I think I have found a subtle .NET serialization bug. It occurs when object has a list of items containing another object of the same type and both objects have a non-static member reference to some other static object. In this case, I get an InvalidArgument exception when I try to access the non-static member of the child class. I've included a code sample to clarify. This "bug" is causing a major problem for me. So, if anyone could confirm it or let me know if I'm doing something wrong, I would be very appreciative. Thanks, Aaron Here is the sample [Serializable] public class A { private ArrayList children; private static Pen DPEN = Pens.Black; private Pen pen = DPEN; public A() { children = new ArrayList(); children.Add(new D()); } public void AddChild(A a) { children.Add(a); } public A Child { get { return (A)children[0]; } } public Pen Pen { get { return pen; } } } public class PenSurrogate : ISerializationSurrogate { public void GetObjectData(Object obj, SerializationInfo info, StreamingContext context) { Pen pen = (Pen)obj; info.AddValue("pencolor", pen.PenType == PenType.SolidColor ? pen.Color : Color.Empty); } public Object SetObjectData(Object obj, SerializationInfo info, StreamingContext context, ISurrogateSelector selector) { return (Pen)info.GetValue("pencolor", typeof(Pen)); } } public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); A a = new A(); A an = new A(); a.AddChild(an); BinaryFormatter bFormatter = new BinaryFormatter(); SurrogateSelector s = new SurrogateSelector(); s.AddSurrogate(typeof(Pen), new StreamingContext(StreamingContextStates.All), new PenSurrogate()); bFormatter.SurrogateSelector = s; MemoryStream stream = new MemoryStream(); bFormatter.Serialize(stream, a); stream.Seek(0, SeekOrigin.Begin); A copy = (A)bFormatter.Deserialize(stream); System.Console.WriteLine(copy.Pen.Color.ToString()); System.Console.WriteLine(copy.Child.Pen.Color.ToString()); //Causes an InvalidArgument Exception } Tag: Debug options Tag: 76697

    - Problems with Compiling COM - newbie HI, I am having problems trying to compile a vb class, the code is below. For some reason it doesn't recognise the namespaces, Data, or Data.SqlClient. In Visual Studio I have created a reference to System.Data, and appears under references, but I can't seem to create one for System.Data.SqlClient as it doesn't appear in the selection. Another thing I should mention is that I am copying the vb class file from our dev server onto my own machine and compiling it on my machine using the VS.net compiler. I intend to copy and paste the dll into bin on the dev server after. What am I doing wrong?????? Thanks Angela -------------CODE----------------------- Imports System Imports System.Data Imports System.Data.SqlClient Public Class SQLTest Public Shared Sub DeleteService(ByVal name As String, ByVal strConnection As String) Dim conPortal As New SqlConnection(strConnection) Dim cmd As New SqlCommand("AdminDeleteService", conPortal) cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add("@communityID", strConnection) cmd.Parameters.Add("@name", name) conPortal.Open() cmd.ExecuteNonQuery() conPortal.Close() End Sub 'DeleteService End Class Tag: Debug options Tag: 76695

    - Best way to sent byte[] parameter to unmanaged code? Using C#, I want to send a byte array to an unmanaged function with the minimum amount of copies. The array is input only and won't be modified (its copied on the unmanaged side). I'm currently using fixed byte *. My question is: Should I be using In byte[] parameter instead? Ref parameter? fixed( byte *b = byte_array ) { MyUnmangedFunc2( b, byte_array.Length ); } [DllImport("foo.dll")] private static extern unsafe void MyUnmanagedFunc2( byte *val, int count ); --OR-- MyUnmanagedFunc2( byte_array, byte_array.Length ); [DllImport("foo.dll")] private static extern unsafe void MyUnmanagedFunc2( In byte[] val, int count ); I need a solution for both the compact framework and desktop framework.

    - Refection/Serialization Problems Hi, I'm trying to build a gerenic routine which deals with versioning problems between serailized objects. All my objects are Serialized into a SQL server DB, but I need to make changes to the object tree and also make future changes easier. I'm using custom serialization and reflection and I think I'm getting there, but I have a wierd problem. I've extracted all the properties from the object in question and passed the info to the following VB routine. It's working fine until it encounters an invalid member in the serializationinfo (which is expected - it's a newly added property in my object), but after that it never recovers - from that point on I'm getting a serializationexeption (member <name> not found) for each subsequent property even when the member definitely exists in the serializationinfo. This only happens AFTER the expected error, until then it's fine. Any clues? Thanks, Russ Private Shared Function CopyObject(ByVal Info As SerializationInfo, ByVal PI() As PropertyInfo, ByRef O As Object) Dim P As PropertyInfo For Each P In PI Try P.SetValue(O, Info.GetValue(P.Name, P.PropertyType), Nothing) Catch ex As Exception End Try Next Return O End Function Tag: Debug options Tag: 76673

    - service timer event WaitHandleWaitOne Hi there all, hope someone recognises this. Problem summary: I have a problem using a timer object within my service class. Whilst the timer triggers happily with delay of 30000 ms for some hours, it eventually comes to a point where no further work is done. Background: I have a service that (when started) I wish to check for work to do every 30 seconds. Therefore I have created a service class with a timer (system.Timers.Timer) and also an object of my service worker class. In the OnStart method I create a new instance of my worker class and load it's configuration. I set the timer interval (held as part of worker's config) and set the timer delay. On each timeout of the timer the timer_elapsed method runs. This stops the timer, does the work using the worker class, starts the timer and then sleeps again. Repeat. The service always appears to be running (in service manager shows as Started) and in task manager the exe process itself is running, but no CPU. If I connect via Visual Studio to the process I cannot get it to hit a breakpoint anywhere. But if I "cheat" and connect to a second service (i.e. another custom process and stop the code in breakpoint relating to that service) then I can see that Visual Studio debugger believes that four threads are running that relate to my app: 1) At the final } statement of my service class.Main method and 2) In System.Threading.WaitHandle.WaitOne 3) & 4) have "no code associated" This second thread leads me 'only' to some disassembly. But no further. Deadlock? As hinted at above: 3 further services run on the same machine and these share a similar format (triggered at time interval) and some code libraries between them. Could anyone point me towards a possible solution or, perhaps more likely, a way to identify further actions towards a solution. Many thanks Matt serviceworker = new CServiceWorker(intLogLevel); System.Timers.Timer sleepTimer = new static void Main() { System.ServiceProcess.ServiceBase[] ServicesToRun; ServicesToRun = new System.ServiceProcess.ServiceBase[] { new ServiceClassName() }; System.ServiceProcess.ServiceBase.Run(ServicesToRun); } private void InitializeComponent() { this.sleepTimer = new System.Timers.Timer(); ((System.ComponentModel.ISupportInitialize)(this.sleepTimer)).BeginInit(); this.sleepTimer.Elapsed +=new System.Timers.ElapsedEventHandler(sleepTimer_Elapsed); this.ServiceName = "ServiceClassName"; ((System.ComponentModel.ISupportInitialize)(this.sleepTimer)).EndInit(); } protected override void OnStart(string[] args) { // do some reading of args and load configuration // create new instance of worker class serviceworker = new CServiceWorker(intLogLevel); long lngTimerIntervalSecs = serviceworker.getTimerIntervalSecs(); setTimerInterval(lngTimerIntervalSecs); } private void setTimerInterval(long lngTimerIntervalSecs) { long lngTimerSleepPeriodMilliSecs = 1000 * lngTimerIntervalSecs; this.sleepTimer.Interval = lngTimerSleepPeriodMilliSecs; // trigger first instance of timer this.sleepTimer.Enabled = true; sleepTimer.Start(); } private void sleepTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { sleepTimer.Stop(); sleepTimer.Enabled = false; // do all the stuff each time timer trigger if(serviceworker.executeMainActivity()) { // execute ok - try again in 30 seconds sleepTimer.Start(); sleepTimer.Enabled = true; } else { // handling removed, but ... // doesn't matter if execute failed - try again in 30 seconds sleepTimer.Start(); sleepTimer.Enabled = true; } } --- Posted using Wimdows.net NntpNews Component - Post Made from http://www.DotNetJunkies.com/newsgroups Our newsgroup engine supports Post Alerts, Ratings, and Searching.

    - ANN: RemObjects Internet Pack for .NET public beta Hello everyone, RemObjects Software is pleased to announce that the public beta of the Internet Pack for .NET is now available for download. Internet Pack for .Net (IP) is the new lightweight and flexible network development framework developed 100% using native C# code. IP supports the Microsoft .NET Frameworks 1.1 and 2.0 (May Preview), the Compact Framework, and Mono (Beta 2). Supported development IDEs include Visual Studio 2003, 2005 (May Preview), and Borland Delphi 8. Internet Pack for .NET is free and includes full source code. STATUS IP is currently in "stable beta" status. This means that we consider the current build to be stable enough to be used in production projects and day-to-day development, but we're planning to incorporate more features and possible fixes in the near future before releasing the "final" version. FEATURES IP is a work in progress, and our goal for version 1.0 was to provide a high-quality framework rather than a large amount of different protocol implementations. Some of the features available in the first release of IP include: - Lightweight and comfortable to use base framework - Flexible and highly scalable architecture - Extendable Connection class allows you to easily integrate custom encryption or compression solutions - Extendable HTTP Client and Server framework - build HTTP applications with just a few lines of code, or easily expand the components to provide complex custom solutions - Extendable FTP Server framework and VirtualFTP sample implementation - CommandBasedServer and Client based components allow you to easily implement your own command based protocols (such as SMTP, FTP Command Connection, etc.) - SimpleHttpServer component provides an easy to implement file-based HTTP Server - SMPT and POP3 Client implementation, Mail Message encapsulation classes - Integration with upcoming DebugServer 3 for easy debugging and tracing DEVELOPMENT COMMUNITY Over time, Internet Pack will become a community project, and we hope that many of its users will contribute with their own extensions and components to the project. Check the urls and newsgroup listed below for more information. ADDITIONAL INFORMATION & DOWNLOAD Download your copy of Internet Pack now, or find more information about the library at http://www.remobjects.com?ip. Our news server is open for discussions about IP (both for users and co-developers) at news://news.remobjects.com/remobjects.public.internetpack.net. Also check out the RemObjects Blogs at http://research.remobjects.com/blogs for regular news and thoughts on the development and progress of IP. We hope that you will enjoy using Internet Pack as much as we have enjoyed creating it, and we look forward to your feedback and comments.

    - How to identify an error? Hi, I want my application do different actions depending on the exception it gets. For exemple: I have an SQL-table with a unique index. In case I try to Insert a record that's alreaddy in it I get this exception: "Cannot insert duplicate key row in object 'tblTelephones' with unique index 'UniqueValues'." What I'm looking for is a way to identify the exception: in case I get this exception I want to do this, in case of another I want to do that. The most simple solution to me seems this: Catch ex As Exception If Left(ex.Message, 41) <> "Cannot insert duplicate key row in object" Then 'do this action End If QAlthough, I'm not convinced this is the best way. Is there a way to identify the exception with a unique number? Or I've seen once something like a name for an error. Can anybody help me with this?

    - Multithreading and DataSet, DataTable, DataRow Hello, if you have defined a DataSet in the HttpApplicationState which is shared by all current users ... what I have to do, to make the Dataset, DataTables and DataRows thread-safe? Following my assumptions: 1) If I change a Row: lock (datarow) { datarow["xy"] = value; } 2) If I add Rows lock (datatable) { datatable.Rows.Add(..) } 3) If I use the Fill method lock (datatable) { adpt.Fill(datatable); // what happens with changed or currently locked datarows? // e.g: process 1 locks row X of datatable A thread 2 wants to lock datatable A, is process 2 waiting for process 1 to unlock row A } 4) If I make AcceptChanges to DataTable or DataRow lock (datatable) { datatable.AcceptChanges(); } 5) For datatable.Remove (lock datatable) 6) For datarow.Delete() (lock datarow) 7) For dataset.Tables.Add() (lock dataset) 8) If I do a datatable.select(...) what a have to do to make it thread-safe? Is this correct or completly wrong? in your applicatoin writes on rows can only be done by one user at the same time, reading should be possible for all users "at the same time".

    - determining files to include in assemblies Hello: I am involved in the development of a NET application and was hoping for some insight into the following question: Outside of deployment considerations, what criteria should be used to determine which classes to include in a given .NET project? For example, if three class definitions, such as Customer, CustomerAccount, and CustomerHistory are in the same namespace, are there any drawbacks to associating each object with a separate project? Would it be preferable to include these three definitions in the same project if they will be deployed to the same machine? Thanks, Chris Tag: Debug options Tag: 76610

    - Remoting and client connections I am attempting to figure out a mechanism whereby I can have multiple clients attached to the same server component, and have all clients made aware of the changes made to a specific data object by one client. There are several layers involved here, and I cannot figure out all of the pieces that I need or how to implement then in C#/.Net. The following is the process as I see it: * I shall define an interface for a 'factory' that permits basic generic operations to be remoted, and acts as a mechanism for requesting conceptual data classes to be created. There shall be a server-side and a client-side class defined for each conceptual data object (customers, orders, etc.) that are supported by the application environment. The heart of each of these classes shall be a DataSet that contains the DataTable and one DataRow that contains the database record for that data object. It shall also be possible to pass a list of data records, or even a set of related records using the same DataSet approach. * The client determines that it wants a reference to a conceptual data object, say a customer, that is identified by a unique identifier, say a CustomerId; the client code invokes the factory object to request that a client side customer class instance be created. * The factory body is remoted and implemented in the server component. The factory holds a 'moniker dictionary' that holds references to all server-side data objects that have been instantiated. a) a search is made in the dictionary for a CustomerObject that has the specified CustomerId b) if found, then a reference to this object is used c) if not found, then a check is made to determine whether the specified customer exists in the database; if it does then a new CustomerServerObject class instance is initialized with the database record, the instance is added to the dictionary and a reference to this object is used d) if a CustomerServerObject was found, then the associated DataSet shall be returned to the client-side wrapper for the remoted interface, which shall instantiate a CustomerClientObject using the same DataSet. e) if no matching data object is found, then some form of MyCustomNoSuchDataObject exception shall be raised and remoted back to the client. #### How do I define the CustomerClientObject class such that it contains a remoted reference to the CustomerServerObject directly? I suspect that a base class common to all such objects would simplify this, but I am not certain how to establish this completely. * Several other clients issues the same request to the factory for the same customer record; all receive a unique CustomerClientObject, but all of them are associated with the same CustomerServerObject. #### How do I define the CustomerServerObject class such that it is aware of all of the clients that have established a connection to that class? * The client shall use methods in the CustomerClientObject class instance to manipulate the contents of the class. Eventually the user shall elect to save the changes or invoke a business action, and this request shall be passed to the server. The request may include the DataSet that contains the single record for this data object or not, depending on the business action requested. * The CustomerServerObject instance for this specific customer performs the requested action, and any changes to the data for this object are automatically saved to the database. For every client other than the requestor, I would like to ensure that the associated CustomerClientObject instance in that client is informed that a change was made (this request does not have to send the change, just the fact that a change occurred, and each client can elect to ask for the changed data or not; alternatively, the change information could include the data itself); it may even be reasonable for the requesting client to receive the changed data in a similar manner. The remoted request then returns its result to the client. * As each client releases its CustomerClientObject instance, the connection with the CustomerServerObject is also released. * When no more CustomerClientObject instances for that specific cusotmer remain, the CustomerServerObject shall be removed from the dictonary and released. I just cannot get my head around the specific techniques required to define the factory and base data object classes to permit this type of connectivity. I had though of using a single remoted class, the factory, as a wrapper (or base class) and have everything go through it, but that makes remoted business rules very complex to maintain and execute. Can anyone aid me in this thinking or point me to specific references that explain how to achieve this in C#/.Net? I am specifically interested in understanding how much of this is built-in to the .Net architecture, as opposed to requiring me to develop all of this capacbility myself on top of the basic remoting facilities. -ken Tag: Debug options Tag: 76605

I have used Windows Update to downlaod and install 1.1, where I notice there is a wizard that allows you to add programs. I don't understand .NETFramework.

    - What account to use with Visual Studio 2003? I just moved from a Windows 2000 /VS 2002 development environment to XP / VS 2003. First I found that in the new environment you must be a member of the Administrators group if the worker process (aspnet_wp.exe) runs under an account other than your own, and by default the worker process runs under the "ASPNET" account, which is specified as "Machine" in the machine.config file. So I made myself part of the administrators group, but found that I could now over-write read-only files, such as files under source control. That seemed like a bad idea, so I took myself out of the administrators group and modified machine.config so the process would run under my own account. Now I find that my account lacks permissions to run aspnet_wp.exe. At least I think that is the problem, even though I gave my account "full control" over that file. All this effort seems absurd. All I want to do is edit projects in Visual Studio 2003. Isn't there a simple way to set up the accounts? Much obliged. Geoff. Tag: Debug options Tag: 76584

    - Losing data sent through network socket I have a server and client that I've written in .NET using the System.Net.Sockets objects, and I am having a bit of a problem. First let me describe what the programs do. The server takes an arbitrary message, encrypts it using a CryptoStream into a MemoryStream, gets an array of bytes from the MemoryStream, and then transmits then length of the encrypted data, followed by the encrypted data down the socket. The client does the exact opposite, reading a 4-byte integer to get the length of the encrypted data, then reading that much data off the socket On the server, the messages that are being pumped out are put on a queue so that the code using the server will not block while waiting for the message to be sent. So I try filling up the queue with a few hundred messages, and the server starts firing them off as fast as it can. The client keeps up with this for a short duration but inevitably crashes at some point because of an IOException or serialization error. The only way I have been able to keep a lid on things so far is to have the server wait for the client to send an acknowledgement byte back to the server once it has successfully read the message from the socket. If I do this I get every message flawlessly, but it seems like there is a better way to handle this, I just have not been able to find it Any help would be GREATLY appreciated Tag: Debug options Tag: 76581

    - MSDE and information_schema.schemata Is it possible that "information_schema.schemata" does not allways work correctly in MSDE Sql-Server. I have built an Explorer that will find the Servers (MSDE and SQL-Server 2000) and then should list the Databases found. For the SQL-Server the results are always correct but not for MSDE. Mostly Databases are missing allthough the results are often diffrent. Selden are all of them there, mostly my two Database are effected in some ways. Different results when called without any changes on the server. Sometimes even one of the four basic Databases is missing. Timeout cannot be the problem since the missing databases are different. They all show up on Enterprise Manager and MSDE Manager. On SQL Query Analyzer however I get the same wrong results. Databases are missing in the TreeView and in the results of "information_schema.schemata" when run. Due to the fact that it also happens in QA I am wondering if the is a general problem that I need not bother me if it is known.
