    - Problem with loosely coupled events I've been fighting with loosely coupled events for the last couple of days, and currently have the following scenario: Interface namespace MyAssembly { public interface IMySink { void OnSyncEvent(); } [EventClass] public class MyEventClass : ServicedComponent,IMySink { public void OnSyncEvent () { throw(new NotImplementedException(exception)); } const string exception = @"You should not call an event class directly. Register this assembly using RegSvcs /reconfig"; } } Message Class public class MyMessage { public string Forename; public string Surname; } Publisher IMySink sink = new MyEventClass(); MyMessage myMessageObj = new MyMessage(); myMessageObj.Forename = "John"; myMessageObj.Surname = "Smith"; // Code for SerializeThis not included string myMessageStr = SerializeThis(myMessageObj); sink.OnSyncEvent(myMessageStr); Subscriber class SynchronisationSubscriberClass :ServicedComponent, IMySink { private MyWindowsFormClass formWindow; public MyWindowsFormClass FormWindow { set {formWindow = value;} } public void OnSyncEvent (string message) { MyMessage myMessageObj = DeserializeThis(message); formWindow.DoSomethingWithMessage(myMessageObj); } } Problem When the OnSyncEvent method is called in the subscriber the instance of formWindow is null. I presume this is because the code is running in a COM+' s memory space and not the memory space that the rest of the application which instantiated the subscriber is running. If this is the case how do I hook back into my main application? Hopefully somebody out there can help me as Microsoft's help in this area is next to non-existent.

    - Permissions for dotnet framework CONFIG directory Hi, I'm running .net on a server under a domain user account (ie. the domain user is specified in the processModel section of machine.config). Please can someone tell me what permissions the domain user account needs on the c:\winnt\microsoft.net\framework\v1.1.4322\config directory. I'm guessing that it's Read and Execute, but I could be wrong. Thanks, Rich Tag: Error while installing library Tag: 84911

    - Problem in deriving class from XmlNode Hi All, I want to make a custom class in c#, which extends System.Xml.XmlNode class of BCL. Now in custom class, I have implement abstract methods of XmlNode class also. Now when I am trying to run the class it gives an error that "System.Xml.XmlNode.XmlNode() is inaccessible due to its protection level". This error comes because XmlNode has not any public constructor. I found XmlNode has two constructor but both are private or friend (i dont know exactly). I also found one MSDN article where it says that "Never derive any class directly from XmlNode" but its just recommendation. (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/ht ml/cpconextendingdom.asp) Though, Microsoft has derived some of BCL classes from base XmlNode, so why we can not derive? System.Object System.Xml.XmlNode System.Xml.XmlAttribute System.Xml.XmlDocument System.Xml.XmlDocumentFragment System.Xml.XmlEntity System.Xml.XmlLinkedNode System.Xml.XmlNotation So i think there must be some way out of this.... So what to do to create a derived class from XmlNode? I heard that many experts are giving their service in news groups. So please help me out of this. I have already derived few of my classes from XmlDocument, XmlElement, XmlAttribute etc. So i dont want to derive from them but i want to derive the class from XmlNode it self. Please help me to get the answer... Thanks in Advance. Thanking you, Mahesh Devjibhai Dhola "Empower yourself...." Tag: Error while installing library Tag: 84907

    - Can I append to an encrypted text file? I need to encrypt messages printed to an application event log. I've copied the approach described in MS "307010 - How To Encrypt and Decrypt a File by Using Visual C# .NET", but I want to append. This MS example (and all other examples I've found) assumes one will read an entire plain text file, encrypt it, then write the entire file to disk. I only want to append individual lines of encrypted text to an encrypted file, then read the thing. Below is a complete console app that shows the code I am using. It "works" if I only write one line to the file and then decrypt, but subsequent lines get mangled. I'd appreciate any advice. using System; using System.IO; using System.Security; using System.Security.Cryptography; using System.Text; namespace CryptoSample { public class CryptoSample3 { private const string Key = "1234abcd"; private const string LogFilePath="C:\\Log.log"; static void LogIt(string Msg) { //append encrypted string to the log using(FileStream LogFile = new FileStream(LogFilePath,FileMode.Append,FileAccess.Write)) { DESCryptoServiceProvider DES = new DESCryptoServiceProvider(); DES.Key = ASCIIEncoding.ASCII.GetBytes(Key); DES.IV = ASCIIEncoding.ASCII.GetBytes(Key); ICryptoTransform desencrypt = DES.CreateEncryptor(); CryptoStream cryptostream = new CryptoStream(LogFile,desencrypt,CryptoStreamMode.Write); byte[] bytearrayinput = new byte[Msg.Length]; bytearrayinput=ASCIIEncoding.ASCII.GetBytes(Msg); cryptostream.Write(bytearrayinput, 0, bytearrayinput.Length); cryptostream.Close(); LogFile.Close(); } } static string ViewLog(string DecryptKey) { DESCryptoServiceProvider DES = new DESCryptoServiceProvider(); DES.Key = ASCIIEncoding.ASCII.GetBytes(DecryptKey); DES.IV = ASCIIEncoding.ASCII.GetBytes(DecryptKey); //read the encrypted file back. using(FileStream LogFile = new FileStream(LogFilePath,FileMode.Open,FileAccess.Read)) { ICryptoTransform desdecrypt = DES.CreateDecryptor(); CryptoStream cryptostreamDecr = new CryptoStream(LogFile,desdecrypt,CryptoStreamMode.Read); return(new StreamReader(cryptostreamDecr).ReadToEnd()); } } static void Main() { LogIt("This is the Message "); LogIt(" This is Message Two "); LogIt(" This is Message Three "); string s = ViewLog(Key); Console.Write(s); Console.WriteLine ("Press Enter to continue..."); Console.ReadLine(); } } } Tag: Error while installing library Tag: 84873

    - converting double to string I have some values in type of double such 0.00009 , 0.0000007, when I want to show them in a text box and convert them to string they are changed to scientific notation while I want to show them as they are. I tried to use tostring("f") but it needs to have a precision number after *f* which will cause always have fix number of characters (for example if use f10 then 0.09 is converted to 0.09000000 while I need to show it as 0.09). do you any suggestion of how I can convert such a numbers to string and show them as they are not as scientific notation?

    - System.OutOfMemory exception: error creating window handle Hi, Software: .NET 1.1 (both non-SP and SP1) Visual Studio .NET 2003 MS SQL Server 2000 SP3 Windows XP SP 2 Hardware: Intel Celeron 1700, Pentium 4 2.4GHz, AMD Athlon 1100 RAM 256-512 DDR I've run into a strange problem. There is an application which allows to: 1) connect to a certain device using a modem 2) manage different aspects (mostly, working with MS SQL Server) Serial communication is done on a separate thread, one per each connection. The maximum number of simultaneous connections is 20. Note: what is written below applies only when running the application not under the debugger. The app starts and works correctly: accepts incoming calls, performs different scenarios, dials out when necessary. When the comms thread needs to modify the UI, it is correctly done using Control.BeginInvoke. However, sometimes (on different computers) the following exception is thrown: System.OutOfMemory exception: error creating window handle ---> System.NullReferenceException: Object reference not set to an instance of object. at System.Windows.Forms.ThreadContext.OnThreadException at System.Windows.Forms.Control.WndProcException at System.Windows.Forms.ControlNativeWindow.OnThreadException at System.Windows.Forms.NativeWindow.Callback(IntPtr, Int32, IntPtr, IntPtr) at System.Windows.Forms.UnsafeNativeMethods.IntCreateWindowEx(int32, string, string, int32, int32, int32, int32, int32, HandleRef, HandleRef, HandleRef, object) at System.Windows.Forms.UnsafeNativeMethods.CreateWindowEx(int32, string, string, int32, int32, int32, int32, int32, HandleRef, HandleRef, HandleRef, object) at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams) -- End of inner exception stack trace -- at System.Windows.Forms.ThreadContext.OnThreadException at System.Windows.Forms.Control.WndProcException at System.Windows.Forms.ControlNativeWindow.OnThreadException at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef, int32) at System.Windows.Forms.Control.SetVisibleCore at System.Windows.Forms.Form.SetVisibleCore at System.Windows.Forms.Control.set_Visible at System.Windows.Forms.Form.ShowDialog(IWin32Window owner) at System.Windows.Forms.Form.ShowDialog at <my form-my code to ShowDialog> What could be the problem?

    - Passing parameters to a thread Hi, I'm running into a thread problem. The context is a distributed application constituted of a controller and several satellites performing a given job. In the controller application, I have to send command requests over the network to a list of satellites. In order to parallelize request sending, I'd like to have each request (one per satellite) sent by a single Thread. The problem is how would a given thread know which satellite he should be taking care of since it seems like I can't pass parameters to a thread. My threads can have access to the list (a Hashtable actually) of satellites, but how would a given thread know exactly which one it should be taking care of ? I would need, at least, to pass an index to each thread... Any idea or comment is welcome. Thanks in advance. Arno Tag: Error while installing library Tag: 84816

    - Compatibility Issues with .NET Framework Hello: My Problem is simple. I develop vb.net applications using VisualStudio 2003, and now there's a strange problem. I wrote a backup application for a friend of mine, using SharpZipLib to create ZIP-Files. Now I installed the latest dot-Net Framework on his Win2K machine, and I got the following error Message: "C:\WinNT\Microsoft.NET\v1.1.4332\mscorwks.dll could not be loaded". I figured out that I always need to install the exact .NET Framework-Version number on the computer the application should be running on, as I used to develop Software, and now I'm afraid to install the latest .NET Service Pack, since I suppose all software that is beeing re-built afterwards won't run on the target computer unless the user also installs the latest service pack. Why is this so, and how can I fix this ? If I create an Installer-application using the Installer-Wizzard in Visual Studio it won't even start, complaining that not the right version of the .NET Framework is installed, and I can only find my exact version of the framework on the Visual Studio DVD nowhere else ! Thanks a lot for your efforts ! Tag: Error while installing library Tag: 84806

If I changed it to friend iParentID0 as integer Of course I could. However I'd like to expose this integer to only certain other classes - in this case forms. Is there any easy way of doing this?

    - Difference between System eventlog and those created by EventLog c Hi, My application write custom event log (i.e. NOT to the standard "system", "application" or "Security" ones) using the EventLog class in .NET. The code is essentially the same as those included in the MSDN library document for EventLog. using System; using System.Diagnostics; using System.Threading; class MySample{ public static void Main(){ // Create the source, if it does not already exist. if(!EventLog.SourceExists("MySource")){ EventLog.CreateEventSource("MySource", "MyNewLog"); Console.WriteLine("CreatingEventSource"); } // Create an EventLog instance and assign its source. EventLog myLog = new EventLog(); myLog.Source = "MySource"; // Write an informational entry to the event log. myLog.WriteEntry("Writing to event log."); } } I found that these event logs I created using EventLog are ***different*** from those default event logs come with XP (again, those "System", "Application" etc.) For one, althogh I can see the event in EventViewer without problem, but when I right click on my event log (for example, "MyNewLog", which is created using the above sample), the properties for it is different from those for the default system event log. The log name field is greyed out (empty) and the Size, Created, Modified, and Accessed values are all empty (shown as "Not avaiable". The problem is that I tried to access my custom event log using the WMI. With script such as this one: Select * from Win32_NTEventlogFile It only returns 3 objects, namely the default system event log ("system", "application", and "security"). My custom event log file is NOT returned. The static EventLog.GetEventLog (in .net) does returns me the correct collections of event log files. But my application requires me to access those files through WMI. I am stuck at here. I have spend quit sometime trying to find out why. Any help will be appreciated. Thanks.

    - Avoiding security issue with URL? I use one page as a template and include a header, footer, and allow the main content area to change, based on a varible I supply via the URL. The variable holds a reference to another page and pulls it into the main page. Going from the main page to pageB will look like: index.asp?p=page Sometimes I append other URL parameters. These may be values, such as a user ID, that goes into the database to set conditions on a stored procedure. This is a security risk. Some one could manipulate this value and access another user's information. What are some examples of good security for this situation? Thanks, Brett Tag: Error while installing library Tag: 84773

    - Parsing of App.config varies by machine I've run into a strage and frustrating problem. I've written some configuration classes that implement IConfigurationSectionHandler to read custom sections in my App.config file. On my primary development machine they work great. This morning I started debugging the application on a different machine and I'm getting ConfigurationExceptions in my classes. The problem seems to be that the App.config is being read differently; it tries to parse whitespace that it didn't on the first machine. Here is my Create() method: public object Create ( object parent, object configContext, System.Xml.XmlNode section) { Hashtable servers = new Hashtable(); foreach (XmlNode srvNode in section.ChildNodes) { NameValueSectionHandler h = new NameValueSectionHandler(); NameValueCollection nvc; nvc = (NameValueCollection) h.Create(parent, configContext, srvNode); // this is where exceptions are being thrown int id = Convert.ToInt32(nvc["ID"]); servers.Add(id, new Server( nvc["Node"], nvc["User"], nvc["Password"], id)); } return servers; } Here is the relevant section of App.config: <Servers> <srv1> <add key="ID" value="1" /> <add key="Node" value="node1" /> <add key="User" value="XXXXXX" /> <add key="Password" value="XXXXXX" /> </srv1> <srv2> <add key="ID" value="2" /> <add key="Node" value="node2" /> <add key="User" value="XXXXXX" /> <add key="Password" value="XXXXXX" /> </srv2> </Servers> I've done some experimenting and found that on the second machine (where the code is failng) the foreach loop is executed five times. On iterations 1, 3 and 5, srvNode contains just whitespace (InnerXml == "" and InnerText consists of \r\n's and \t's) and on iterations 2 and 4 srvNode contains the proper child nodes (<srv1> and <srv2>, respectively) as expected. On the machine I originally wrote the code on, the loop is executed only twice, once for each child node of <Servers>. Does anyone have an explanation for this? I haven't changed any machine-level configurations that I'm aware of. Thanks. Tag: Error while installing library Tag: 84744

    - Regex Woes I'm attempting to check a string and see if it has any other characters besides numeric. Using the following pattern "[^0-9]*", I figured it would find a successfull non-numeric character if it was matched against a string and it does just fine. My question/problem is that when I match the pattern against a string simply like "3", even though there aren't any non-numeric characters present, it still reports success. I wrote this pattern using Expresso (http://www.ultrapico.com) and when using Expresso, the pattern behaves as expected (reports success when non-numeric char's are presents and doesn't report success when only numeric char's are present). However when using the following snippet: Regex ex = new Regex(@"\D*"); // or @"[^0-9]*" if (ex.Match("3").Success) Console.WriteLine("I'm busted"); It seems to find a match even though I'm explicitly telling it to match non-numeric characters. Any ideas? Thanks! - James http://www.dotnetwookie.com/blog/hamaze/ Tag: Error while installing library Tag: 84739

    - Object deserialization issue I have a class marked as [Serializable]. This class contains private members that I don't need to serialize, as such I've tagged their declaration as [NonSerialized]. Most of these members are initialized in the constructor of my class. The serialization and deserialization works fine BUT, when deserializing (hence re-creating objects graph) I'm loosing these non-serialized members initialization. I thought that the object constructor would be executed anyhow, which doesn't seem to be the case. Here is my code snippet: [Serializable] public class Satellite { private String ip; // This member will be serialized private int port; // This member will be serialized [NonSerialized] private String _status; // Volatile info, no need to be serialized [NonSerialized] private int _statusCode; // Volatile info, no need to be serialized public void Satellite() { this._status = "Unknown"; this._statusCode = 0; } } Any idea, comment or documentation pointer is welcomed. Thanks in advance. Arno Tag: Error while installing library Tag: 84738

    - Class Library Reference --> Javadoc Style I am coming from the Java World, and I was wondering if anyone knew of a tool, or XSL document, that would convert the normal Tree based Class Library docs to have the same format as Javadoc does? For example, it would have 3 Frames: Top Right Col: Namesapces Bottom Right Col: Class in Namespaces Left Col: Methods/Properties, etc of the Class selected in the bottom Right Col.

    - *URGENT Comparing objects stored in hashtable/collection Hi! I need to compare objects that I store in HashTable by using Add method and passing object as first param, and a unique key string as second. Later on I iterate through this collection and need to compare the object stored in the HashTable to another object that's obtained as one of the params in a call to an event. Example code (i'm skipping most declarations to avoid long post): Private Shared Sub OnChanged(ByVal source As Object, ByVal e As FileSystemEventArgs) Dim fsw as FileSystemWatcher fsw = source myEnumerator = hshtable.GetEnumerator() While myEnumerator.MoveNext if myEnumerator.Value Is fsw then 'do something if the object is the same end if End While I also tried using myEnumerator.Current when performing comparison, as well as trying to cast the .Value and .Current to the same type of object that I compare it to (FileSystemWatcher). I'm open to any suggestions. The basic goal of what I'm doing is to store a reference to an object and an associated string somewhere so that I can later when the event of FileSystemObject fires identify that object and associated string to perform some relevant action. I have a pretty short Deadline on this so any help would be appreciated! Thanks! Tag: Error while installing library Tag: 84722

I'm receiving an error message when trying to reference my dll I've just
built and installed on my development workstation. Where can I find the
proper procedures for developing and then conducting a user test of
installation of the dll on the same machine?
Do I have to unregister the com library first and then install or does the
setup installer take care of that for me?

What error are you getting?
Are you trying to use the component from VB/Excel/script? You don't need to register .NET assemblies to be able to use them normally

I was getting an error Object null reference even though I had a reference
to my dll. When I used '<Assembly: PrimaryInteropAssembly(1, 0)>' in my
assembly info file my problem went away.
