    - Register insertion of USB drives in .NET 1.1 Hi there, I'm trying to write something in VB.NET that registers the insertion of a USB device (specifically a USB flash drive) and acts upon the event. I've done some reading up and it seems that using ManagementEventWatchers is the way to go, yet using the code below in a test project, I find that inserting a USB drive triggers up to about 5 events instead of just the 1 I'm expecting. If anyone could point out the error of my ways that'd be great. Cheers Paul Taylor Imports System.management Public Class Form1 Inherits System.Windows.Forms.Form .. Dim query As WqlEventQuery Dim WithEvents watch As ManagementEventWatcher Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load query = New WqlEventQuery("Select * from Win32_DeviceChangeEvent") watch = New ManagementEventWatcher(query) watch.Start() End Sub Private Sub w_EventArrived(ByVal sender As Object, ByVal e As System.Management.EventArrivedEventArgs) Handles watch.EventArrived MsgBox("Event!")

    - Stop 0x000000E0 param: 0x00000001, 0x80000003, 0x00008080, 0x80e92000 Hello. Ok. I have the job of fixing an ibm thinkpad 600e model 5A0 and have a weird problem. I was running xp quite successfully albeit slowly without any issues until I turned it on and now I am getting a stop error. Stop: 0x000000E0 param: 0x00000001, 0x80000003, 0x00008080, 0x80e92000 I am a bit techy and have the job of fixing it :( I know that the stop error error 0x000000E0 refers to the ACPI bios. However it works in safe mode and other os and indeed xp until recently. The bios version is : INET24WW, 05/24/1999 I know this could be updated but I hate the idea of updating the bios (in case it goes wrong) and it worked before. However, When running a test on the system board using the bios it reports an error: DEV 001 ERR 91 FRU 3610 I am not too sure what these errors refer too but believe it's something to do with the battery. Besides, if there was an hardware error inside the bios wouldn't it also fail in safemode? Another sceptical moment! Of course, I have tried running msconfig and disabling all startup items and have disabled all options in win.ini, boot.ini etc. I have managed to do this from safe mode. I cant run sfc /scannow cos its in safemode or system restore as it generates an error, indeed getting into the event logs results in an error so I have the stop errors to work from. The people who owned this machine also has a lot of documentation on here. There is no built in nic card and I cant install anything else until I sort out the other stuff. The only real option I could do is use a ubuntu live cd and hope I can mount it and copy stuff over!!!!!! So, if anyone can provide a solution that does not require reinstalling, it would be greatly appreciated. Cheers John -- www.integrated-dev-sol.co.uk Remove 123 from email address to reply.

    - Making a Winforms app behave like a Console app I am attempting to add a "console mode" to my Winforms app. My intention is that when I start the app with a special switch (for example "myapp.exe /batch") to does not launch a graphical UI but instead just displays console messages. My first guess was to simply change the Main method of the startup class to do something like this... if (batchMode) { Console.WriteLine("Now in batch mode"); ... } else { MainForm.Run(); // Launch graphical user interface } Unfortunately, it looks like my app does not behave like a real console mode app in either case. When I execute the app from the command line, the app returns immediately and text output by Console.Write() does not appear anywhere. Setting the app as a Console mode application does not give me what I want either. With this mode, a big black console output box appears even when in "GUI mode". Is there a way to build one executable that supports both modes and dynamically switches at runtime? Tag: SetOwner The security identifier is not allowed to be the owner of this object Tag: 110881

    - Assembly Security Is it possible to create an assembly (Namespace A) and set it so only certain assembly can load it and invoke methods on it. For example, only Namespace B and Namespace C would be able to invoke Namespace A because of this security setting. Is this possible? if yes I would really appreciate it you could let me know if possible or not and how? Many thanks!

    - Event name from EventHandler or Delegate? I have an application in which I need to fire an event from some class other than the one that has defined the event. I am trying to do this by finding the delegate associated with the event in question, and then by calling GetInvocationList() and invoking each EventHandler in turn. And although I've found some nice links to back-door techniques on how to retrieve a delegate for a given event, those techniques don't seem to work for me. I've figured out an alternative method, but it's not quite working the way I want it to...yet. Alex Feinman (http://www.opennetcf.org/PermaLink.aspx?guid=4cf118ee-5668-452e-af2c-f3a0c6d43a7f) and others have suggested a technique where you cycle through the private fields of a type looking for one that has the same name as the event of interest. For example, to find the delegate for the Click event for button1, and then emulate the button-click event on that button: Type t = typeof(Control); FieldInfo fi = t.GetField("Click", BindingFlags.NonPublic | BindingFlags.Instance); Delegate handler = fi.GetValue(button1) as Delegate; foreach (Delegate d in handler.GetInvocationList()) { d.Invoke(button1, new EventArgs()); } Only trouble is, this doesn't work for me. I can't find this private field. What "almost" works instead is something like the following, but it returns *all* delegates, and by, extension, all event handlers, for the associated control, not just the ones associated with the Click event or some other event of interest. So my question is, given an instance of an EventHandler or Delegate, is it possible to determine which Event that EventHandler or Delegate is associated with? // button1 is defined as a Button, and it has added an EventHandler // to the chain of handlers that handle the Click event. It has also // defined some handlers to handle other events and has added those // handlers to the chain of handlers associated with those other // events. Every non-null delegate for the control is returned by // findDelegates(), not just the Button.Click event delegate. ArrayList allDelegates = findDelegates(button1); // The following will cycle through ALL delegates. not just the ones // associated with the Click event. This is not good.... foreach (Delegate del in allDelegates) { Delegate[] theseDelegates = del.GetInvocationList(); foreach (EventHandler thisHandler in theseDelegates) { thisHandler.Invoke(buttonDemo, new EventArgs()); } } // What I would like to do: // Delegate buttonClickDelegate = findDelegateFor(button1, "Click"); // and then invoke this delegate's handlers as above. ... protected ArrayList findDelegates(object o) { ArrayList rc = new ArrayList(); // Event-handler information for a given instance // of an object should be accessible through a private field // of type EventHandlerList. And this field probably won't // be defined for the current class type of object o. // The field will probably be defined as part of a base // class that is buried several classes deep in the // inheritance chain. // findFieldType will recurse through the type tree for // the caller-specified object until it finds a field of type // EventHandlerList FieldInfo f = findFieldType(o.GetType(), typeof(EventHandlerList)); if (null == f) { return rc; } EventHandlerList ehl = (EventHandlerList)f.GetValue(o); if (null == ehl) { return rc; } // The EventHandlerList class doesn't expose what we need. // We need to get to the private fields...to the contents of the // linked list that is contained within the class. Each entry in // the linked list is of type ListEntry (a private nested class // apparently defined within EventHandlerList) and represents // one delegate. The event handlers for that delegate can then // be accessed using the publicly visible GetInvocationList() // method. FieldInfo headFieldInfo = ehl.GetType().GetField("head", BindingFlags.NonPublic | BindingFlags.Instance); if (null == headFieldInfo) { return rc; } object headField = headFieldInfo.GetValue(ehl); // findDelegate will populate the caller-supplied ArrayList with // all delegates in the linked listed headed by headField. // What we really need is a way to get only those delegates // associated with a specific event. findOneDelegate(headField, ref rc); return rc; } /// <summary> /// Walk through the linked list represented by the caller-supplied /// ListEntry object and extract delegates from that list. /// Each event exposed by a given control is represented by one linked /// list entry. There may be multiple delegates to handle the event, /// but those delegates are retrieved using the GetInvocationList() /// method and not by using this back-door stuff. /// </summary> /// <param name="o">A linked-list entry of type ListEntry</param> /// <param name="delegateList">A reference to a delegate list ArrayList /// that is recursively populated</param> protected void findOneDelegate(object o, ref ArrayList delegateList) { if (null == o) { return; } object next = null; foreach (FieldInfo fx in o.GetType().GetFields( BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)) { object thisObj = fx.GetValue(o); // thisObj is of type ListEntry. It has 3 fields: // next -- the next ListEntry in the linked list, // key -- an object. Obviously this identifies the event, but how?? // delegate -- a delegate if (fx.Name.ToLower() == "next") { next = thisObj; } if (fx.Name.ToLower() == "key") { Trace.WriteLine("Key type: " + thisObj.GetType().Name + "; hashcode: " + thisObj.GetHashCode().ToString()); } if (fx.FieldType.Name.ToLower() == "delegate") { delegateList.Add((Delegate)thisObj); } } if (next != null) { findOneDelegate(next, ref delegateList); } } Tag: SetOwner The security identifier is not allowed to be the owner of this object Tag: 110869

    - Changing selected index of dropdown is not reflected when posted back? Hi all, Using .Net Framework 1.1 (with latest patch), I have a page with your typical DropDownList control. There is logic that causes the selected value (or selected index) of the drop down to be reset or changed via javascript. This happens great on the page, but when the I try to access the DDL.SelectedValue on the server, the value is always the option that was initally set. Even if I manually select an item prior to the javascript "re-selecting", the selected value is the initial value. Any ideas?

Is there a way to design this so that the main base, skeleton of the program is seperate from the customization and the different customizations can be loaded like a snap on module?

    - do I need the .NET framework? Many pardons if this is the wrong group to ask this question. After replacing a failed hard disk, I installed XP home and all critical updates including SP 2. When I try to install Office 2000 premium, it can't find several DLL files and eventually fails to install. When I run windows update, it shows .NET 1.1 and 2 in the available updates. Does this mean that I do not have .NET of any version installed and if so could this keep office 2000 premium from installing? Office 2000 premium was working well before the disk failure. I don't know why I can't install it now.

    - Problems authenticating server for SSLStream negotiation This is absolutely driving me nuts. Any hints would be GREATLY appreciated. I am trying to negotiate a clear channel socket to SSL. Thing is it works great on two development computers, but falls flat on its face when I go to deploy to a server. I have written both CLIENT and SERVER for FTP. When the client issues the appropriate command I call the SSLStream.AuthenticateAsClient, while at the same time the server is calling SSLStream.AuthenticateAsServer. I have played with using a number of different host names on the client side, to no avail. On the server side I reconstitute the server certificate from the registry, where I have it stored as a binary block of data. A utility loads the PFX file, which includes the private key, then stores that in the registry. Later, when the FTP server starts I load the binary data, and use it to construct the Certificate, which is eventually used to negotiate SSL. The PFX was built at the server by importing our certificate, and then exporting to PFX, supplying the password, choosing to include the private key, and to NOT delete the key after export. On the two development computers that I went through all of these steps on (using the PFX generated at the production server), it all works wonderfully. When I do the same at two different servers, the negotiation fails. SChannel errors are logged in the system event log. Event ID 36870, "A fatal error occurred when attempting to access the SSL server credential private key. The error code returned from the cryptographic module is 0x80090016." When the FTP service starts I pull the certificate from the registry as described above, and verify the chain. All 3 elements on the chain are valid. The server call to AuthenticateAsServer crashes as such: 09:16:44.97 NegotiateSSLServer unable to authenticate. 09:16:44.99 - System.ComponentModel.Win32Exception: The credentials supplied to the package were not recognized 09:16:44.99 at System.Net.SSPIWrapper.AcquireCredentialsHandle(SSPIInterface SecModule, String package, CredentialUse intent, SecureCredential scc) 09:16:44.99 at System.Net.Security.SecureChannel.AcquireCredentialsHandle(CredentialUse credUsage, SecureCredential& secureCredential) 09:16:44.99 at System.Net.Security.SecureChannel.AcquireServerCredentials(Byte[]& thumbPrint) 09:16:44.99 at System.Net.Security.SecureChannel.GenerateToken(Byte[] input, Int32 offset, Int32 count, Byte[]& output) 09:16:44.99 at System.Net.Security.SecureChannel.NextMessage(Byte[] incoming, Int32 offset, Int32 count) 09:16:44.99 at System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest) 09:16:44.99 at System.Net.Security.SslState.ProcessReceivedBlob(Byte[] buffer, Int32 count, AsyncProtocolRequest asyncRequest) 09:16:44.99 at System.Net.Security.SslState.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest) 09:16:44.99 at System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest) 09:16:44.99 at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) 09:16:44.99 at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult) 09:16:44.99 at System.Net.Security.SslStream.AuthenticateAsServer(X509Certificate serverCertificate, Boolean clientCertificateRequired, SslProtocols enabledSslProtocols, Boolean checkCertificateRevocation) 09:16:44.99 at ODP.NMServe.TCPClientSSL.NegotiateSSLServer(X509Certificate2 Certificate, Boolean ClearReceiveBuffer) Tag: SetOwner The security identifier is not allowed to be the owner of this object Tag: 110799

    - deploying wrapped dlls Hello The application I'm building an installer for uses dlls which were developed originally in C. Since the application itself is developed in C#, these dlls were wrapped using SWIG. Initially, the machine environment variables were set to enable code development; however, I am facing problem deploying the application. To work with these wrapped libraries, the application seems to access a specific dll, for instance, let's say the C assembly name is A.dll, it seems to be making attempts at invoking its wrapped version, Awrapped.dll. In the case of my application though, this invocation is producing a DLLNotFound exception. If the installer sets the environment variables, then the application is able to pick up the wrapped dlls. If, however, the path to these wrapped dlls is specified in the application configuration file as <probing privatePath = "..." />, the dlls are not found. I don't have the source code for these dlls. Initially, I had thought that if somehow I could get access to the source code, I would be able to strongly name the dlls and then wrap them. Perhaps that would have allowed me to use assembly binding policies to find the specific dlls. But now I think even that would not have helped. Is there a special method for deploying wrapped dlls? Could someone tell me if this problem is being cause because of the dlls being wrapped? Thanks Tag: SetOwner The security identifier is not allowed to be the owner of this object Tag: 110790

    - Finding and Creating Assemblies?!? fuslogvw I am trying to track down an annoying and deep-seated bug in a custom designer for a custom component. In the course of trying to figure out why certain errors are occuring I ran fuslogvw to see exactly what assemblies are being loaded when my application loads into VS2003. I was astonished to see that an assembly I no longer use/reference in the project gets loaded. I was even more astonished to see that the framework went back and re-created the directory structure of the project which used to create the "old" assembly, and plopped a copy of the old assembly into it. Why is this happening? How do I stop it? What do I do in the future to keep stale/old assemblies from being re-introduced to my projects? - Mark Tag: SetOwner The security identifier is not allowed to be the owner of this object Tag: 110789

    - AppDomain and PrivateBinPath Hi together, I have got a question according to AppDomains and their PrivateBinPath property. I am doing the following: ------> SNIP AppDomainSetup actSetup = new AppDomainSetup(); actSetup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; actSetup.PrivateBinPath = @"Lib2;Lib1"; AppDomain firstLibDomain = AppDomain.CreateDomain(Guid.NewGuid().ToString(), null, actSetup); IClassLibrary actLib = firstLibDomain.CreateInstanceAndUnwrap("MyLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=397a36feab9afc6a", "ClassLibrary.Test") as IClassLibrary; --------< SNAP So everthing is fine. As you can see there are two subdirectories: Lib2 and Lib1 in the private bin path. Now when I have an assembly with the fully qualified name like: "MyLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=63f75bd8dc418e77", "ClassLibrary.Test" (the only difference is the public key token) in the Lib2 subdirectory and "MyLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=397a36feab9afc6a", "ClassLibrary.Test" in the Lib1 subdirectory. I get the following error in the fusion log. WRN: Comparing the assembly name resulted in the mismatch: PUBLIC KEY TOKEN ERR: Failed to complete setup of assembly (hr = 0x80131040). Probing terminated. Which means that he finds the assembly name, but the public key token doesn't match. So the loading mechnism stops here instead of looking in the other subfolder Lib2 where the matching assembly would be. If I put both assemblies in the GAC I didn't have any problems. So I am wondering, I thought that I could get this running with AppDomain too? Any ideas what's wrong here????

    - How do C# delegates in .NET work under the hood? C# Delegates And Events in Depth After a couple of years of programming in .NET I finally took time to investigate in detail how exactly C# delegates and events work under the hood. Topics covered in this article include: Class Delegate. Class MulticastDelegate. Field-like events. Event accessors. Virtual events. Delegate Class Every delegate object in your code is implicitly derived from class Delegate. This class is special in a sense that only system and compilers and create types derived from it. C# and VB.NET programmers cannot derive explicitly from Delegate. I am not sure whether this limitation holds for programs written directly in IL (will verify it some day). Delegate class has two main properties - Target and Method.Target references an object instance, and Method describes a method implemented by that instance. To invoke a delegate means to take Target object and call its method described in Method. For example: delegate void MyDelegate(); class MyClass { public void SomeMethod() {...} } ... MyClass myClass = new MyClass(); MyDelegate d = new MyDelegate( myClass.SomeMethod ); // now d.Target is myClass, and d.Method describes MyClass.SomeMethod Note that Delegate represents a unicast delegate, which referes to a single method. Delegates and Static Methods What is the Target of a delegate which points to a static method? For the outside world, Target property of such a delegate returns null. But this is not the whole story. Internally delegate stores its target in a private field named _target. Normally, public property Target just returns a value of _target. Not so for static delegates. For static delegates, _target contains a reference to the delegate itself. "Get" accessor of Target makes a quick check, and if _target references a delegate, returns null. I am not sure what are the reasons for this balancing act. Equality of Delegates Non-static delegates are equal if their targets are the same (i.e. are ReferebceEqual()), and their Methods point to the same method (i.e. are Equal()). This means that delegates can be considered equal even if they belong to different delegate types. For instance, example below prints "Delegate equality: delegates are equal". public class DelegateEquality { delegate void DelegateTypeA(); delegate void DelegateTypeB(); private void TestMethod() {} public void DoTest() { DelegateTypeA a = new DelegateTypeA(this.TestMethod); DelegateTypeB b = new DelegateTypeB(this.TestMethod); bool areEqual = Object.Equals(a,b); if (areEqual) { Console.WriteLine("Delegate equality: delegates are equal"); } else { Console.WriteLine("Delegate equality: delegates are not equal"); } } } Static delegates are equal if their Methods point to the same method. MulticastDelegate Class Class MulticastDelegate derives from Delegate and represents a delegate that can invoke more than one method at once. All delegates that you create in C# are multicast delegates. Internally, MulticastDelegate is implemented as a linked list of delegates. Delegates are stored in the list in the reversed order of execution. I.e. if we execute the following code: Class1 object1 = new Class1(); Class2 object2 = new Class2(); MyDelegate d = new MyDelegate(object1.Method1); d += new MyDelegate(object2.Method2); delegate d is represented in memory as follows: This representation is convenient, because additions and removals are usually done in the end of the list. Invoking the delegate is implemented via recursion: invokaction code first invokes Previous delegate (which recursively invokes the whone chain), and that calls Target.Method. Note that due to this representation Target and Method properties of a multicast delegate always return Target and Method of the delegate most recently added to the list. Adding and Removing Delegates All delegate types declared in C# have implicit operators += and -=. Adding a delegate to a multicast is straightforward: a+=b appends b to the invocation list of a. Removing delegates is based on equality. a-=b removes last occurence (in execution order) of a delegate equal to b from the invocation list of a. If invocation list of a becomes empty, a becomes null. Removal by equality allows us to get away with code like this: MyDelegate a = null; a += new MyDelegate(object1.Method1); a -= new MyDelegate(object1.Method1); Delegates passed to += and -= are not the same, but they are equal. Since removal is based on logical equality, and not reference equality, it works fine in this case and a becomes null as we expect it to. Null Delegates There is no such thing as delegate without an invocation list. Whenever invocation list becomes empty, delegate becomes null. Calling null delegate is a run-time error. Therefore, whenever someone calls a delegate, he/she must check it for null, or else. MyDelegate a; ... if (a != null) { a( parameters ); } I am not sure why Microsoft decided not to make this check automatic. After all, calling a delegate without the check rarely makes sense. A situation when we can absolutely guarantee that the delegate is not null, and when we do really worry about extra couple of cycles spent on the check, seems to occur pretty rarely. If really necessary, for the situation like this a special way to do "nocheck" calls could be provided, but checked call should be the default. Unfortunately, it isn't. Events When I started programming in C#, it took me certain effort to understand the difference between events and delegates in .NET. C# syntax makes them to look deceptively similar: MyDelegate a; // delegate event MyDelegate b; // event Don't let the syntax fool you. Conceptually, event is a pair of methods: add accessor and remove accessor. Each method takes a single parameter of specific delegate type. Add accessor is invoked via "e+=d" expression, remove accessor is invoked via "e-=d" expression. Event accessors can be explicitly declared as follows: class MyClass { public event MyDelegate GoodNews { add { // add accessor code here } remove { // remove accessor code here } } } After seeing full event declaration syntax, it becomes clear that events are more similar to properties than to delegates. Unlike property, event cannot have just one accessor - it must always have both. Note that event does not provide a "call" or "raise" accessor. This is because entities outside declaring class are not supposed to raise the event. In other words, raising is not part of event's public interface - it is an implementation detail. Using Events Users of event register their delegates using operator += and remove them using operator -=. This is all they can do with the event. Class that implements the event is supposed to invoke registered delegates at specified moments, e.g. when mouse button is down, or when socket data arrives, etc. However, what and when to invoke is entirely up to the author of the class. In particular, there is no guarantee that the class will invoke all the delegates that have been registered. Theoretically, the class can ignore every other delegate, or call only delegates whose target is derived from MarshalByRefObject. Of course, although theoretically possible, in reality such picky classes either don't exist, or are a negligible minority. Implementing Events Most typical implementation of an event would be as follows: class MyClass { public event MyDelegate GoodNews { add { lock(this) { _goodNews += value; } } remove { lock(this) { _goodNews -= value; } } } private void OnGoodNews() { if (_goodNews != null) { _goodNews(); } } private MyDelegate _goodNews; } Figure 1 Here we use private delegate _goodNews to store invocation list for the event. This is not the only possible implementation, however. Let's consider a situation when our class defines lots of events, and typically only a couple of events is actually hooked up for a particular instance of the class. In this case, storing lots of private delegates would be a great waste of space. Each instance of the class would carry all the delegates, and only a few of them would be actually used. The solution is to hold in each instance a container that stores only actually used delegates. This is exactly how event-rich UI classes like Control handle their events. Field-Like Events Implementation of an event outlined in Figure 1 is by far more common than any other. In fact, it is so common that authors of C# language added a special syntactic shortcut for it. If a class declares a non-abstract event without add and remove accessors, compiler automatically generates default accessors similar to those in Figure 1, and adds an anonymous private delegate field that stores invocation list for the event. Such "default" events are called "field-like events". See section 10.7.1 of C# Language Specification. In addition, when name of field-like event is used inside the class it refers not to the event itself, but to the anonymous private delegate created by compiler. class MyClass { public event MyDelegate GoodNews; private void OnGoodNews() { if (GoodNews != null) { GoodNews(); } } } Figure 2 Code in Figure 2 is functionally equivalent to code in Figure 1 . Note, that anonymous delegate is private, and therefore not accessible anywhere, but in the class that declares the event. In particular, the following code does not compile, because derived class does not have access to the anonymous delegate: class MyClass { public event MyDelegate GoodNews; } class Derived : MyClass { private void OnGoodNews() { if (GoodNews != null) // bad! { GoodNews(); // bad! } } } Also, if event is not field like, there is no anonymous delegate that backs it up, and the only things anybody (declaring class included) can do with it are += and -=. For instance, the follownig will not compile: class MyClass { public event MyDelegate GoodNews { add { ... } remove { ... } } private void OnGoodNews() { if (GoodNews != null) // bad! { GoodNews(); // bad! } } } Virtual Events If event is declared with the keyword virtual it makes its acessors virtual. Field-like events can also be virtual. Derived classes can override accessor methods with their own implementation. E.g. class MyClass { public virtual event MyDelegate GoodNews; // field-like private void OnGoodNews() { if (GoodNews != null) { GoodNews(); } } } class Derived : MyClass { public override event MyDelegate GoodNews { add { Console.WriteLine("Adding delegate to GoodNews event"); base.GoodNews += value; } remove { Console.WriteLine("Removing delegate from GoodNews event"); base.GoodNews -= value; } } } Event can also be abstract. It means that add and remove accessors are abstract and derived classes must provide their own implementation. Virtual Events Gotchas If derived class provides its own implementation of add and remove accessors, which puts event invocation list in its own storage, base class has no knowledge of how to invoke the event. Consider the following code: class MyClass { public virtual event MyDelegate GoodNews; // field-like private void OnGoodNews() { if (GoodNews != null) { GoodNews(); } } } class Derived : MyClass { public override event MyDelegate GoodNews { add { lock(this) { _goodNews += value; } } remove { lock(this) { _goodNews -= value; } } } private delegate MyDelegate _goodNews; } Whenever base class invokes the event, it will call only delegates stored in Base.GoodNews. However, GoodNews+=d and GoodNews-=d will oeprate on Derived._goodNews, of which base class has no knowledge. This is resolved by making function OnGoodNews protected and virtual. If derived class overrides event accessors, it must also override the function that invokes the event. Summary All C# delegates implicitly derive from class MulticastDelegate, which is a linked list of target/method pairs. Delegates are compared by logical equality, not by reference equality. Event is nothing more than a pair of methods. As such, it can be made part of an interface, virtual, abstract, et cetera. "Raise" operation is not part of event behavior. Field-like event is a syntactic shortcut that implements event based on a private anonymous delegate. Delegates and events are important mechanisms of C# language.

    - ISO8601 DateTime format Hi, "2006-01-27T07:42:11.3014976-08:00" is an example how a DateTime gets serialized from a ASP.NET web service. This represents the ISO8601 format. For some reason when I read such a value from a MySQL database, initialize a DateTime object which gets returned by a web service it ends up coming back as "2006-01-27T07:42:11". This only happens when using .NET framework 2.0. In the framework 1.1 it always serialized the full DateTime including the timezone offset as shown on top. Does anybody know how to make sure it always serializes it to "2006-01-27T07:42:11.3014976-08:00"? Thanks.

I understand that the ASP.Net version is the version of ASP.Net that the current site is running under and it can be retreived with System.Environment.Version.ToString. What exactly is the Microsoft .NET Framework Version that is displayed? It is NOT the highest version of the framework installed, because I have 2.x and just got the following at the bottom of a 1.x error page: Microsoft .NET Framework Version:1.1.4322.2048; ASP.NET Version:1.1.4322.2032. Note that the version numbers are just slightly different (while my 2.x pages return the same 2.x version numbers.) How can this number (whatever it refers to) be programmatically retreived? I've been searching newsgroups and MSDN for quite a while and no one seems to know the answer (the code above is often incorrectly referred to as being the way to get it, but it only returns the running ASP.NET version.) Since it and the ASP.Net version can differ on the same page, this MUST be come from a different version number than System.Environment.Version.
