    - Framework 1.1. Service Pack1 - Windows 2003 Hi, We're using Windows 2003 server with .NET framework 1.1. Recently installed Service Pack 1. After that our ASP.NET pages don't post back when required field validators have been used. We tried copying old WebUIValidation.js. We tried aspnet_regiis -c and iisreset. Nothing seems to solve the problem. We could not uninstall the Service pack 1 also as some other dependencies are there. Can anyone help?

    - DataSets Is there a way to use SQL like terminology but instead of accessing a database use DataSets? I ask because in the current project I am doing there is need to create tables dynamically as results of queries. These tables are then used proceed to the next step. In a server environement I can see where if several people were doing the same task and creating the same table there would be conflicts. So I thought, what if I could generate DataSets and then manipulate them in memory without creating temporary tables in the database to do the work. However, outside of setting up simple parent-child relationships(joins) for DataSets I don't see many options in manipulating relations between datasets. For instance, I would need to create joins between DataSet and tables in a database. I also need to create Cross Joins between datasets. Thank you in advance, Eric Tag: creating a hierarchical dataprovider Tag: 84976

    - MenuItem popup event Hey, I have a context menu which is being built dynamically. The menu has regular items and group items which contain sub menu items. I didn't want to create the menu all at once, so I decided I will create the sub menus on the popup event of the parent menu item. The trouble is that the event handler that I registered on popup is never called (I did add a dummy menu item, so the popup SHOULD fire). I tried registering the select event and that 1 works. Any1 has a clue?! MenuItem GroupMenuItem = new MenuItem(FolderName); //create group menu for folder GroupMenuItem.MenuItems.Add(""); //add dummy menu item so it will display as a group and raise the Popup event GroupMenuItem.Popup += new EventHandler(GroupMenuItem_Popup); //assign popup event handler DynamicMenu.MenuItems.Add(GroupMenuItem); //add new group menu when i select the groupmenuitem, the function GroupMenuItem_Popup is never called, altough i checked in debug and onPopup has this function...

If I move the currency manager in code, the grid's selected row does not follow. However, if I fill and bind the grid after load, then moving the currency manager works correctly. The application is loading from a url and is running with only internet permissions. If the application is running in the intranet zone everything works correctly.

    - dotnet framework 2.0 If I download the 2005 beta express versions and install them, will the .NET framework 2.0 (beta) replace the existing 1.1 (non-beta) that's on my machine? What I mean is will I have two versions side by side - i.e. is the beta marked as 'this version is not allowed to replace an existing one' but a non-beta isn't marked with that, is what I'm trying to get at. And if 1.1 is installed over the top of 1.0, then does it replace it, and if so, does an application developed with 1.0 still run against 1.1? When 2.0 (non-beta) is out, will it then replace 1.1 and will 1.1 applications still run against it? Thanks Tag: creating a hierarchical dataprovider Tag: 84949

    - 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.

    - 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: creating a hierarchical dataprovider 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: creating a hierarchical dataprovider 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?

    - 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: creating a hierarchical dataprovider 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 !

I created a simple Windows Application with 1 button that executes the code below. It is trying to load a very simple assembly 'ClassLibrary1' that is located in the GAC. The call to CreateInstanceAndUnwrap is unable to locate the assembly. I have no clue as to why the application domain can't load a shared assembly, any help is welcome. // Prepare Setup AppDomainSetup appDomainSetup = new AppDomainSetup(); appDomainSetup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; appDomainSetup.ApplicationName = "MyAppDomainName"; // Create Application domain AppDomain myAppDomain = AppDomain.CreateDomain("MyAppDomainName", null, appDomainSetup); try { // Load shared assembly myAppDomain.CreateInstanceAndUnwrap("ClassLibrary1", "ClassLibrary1.Class1"); } catch(Exception ex) { // Crashes with message "File or assembly name ClassLibrary1, or one of it's dependencices was not found." MessageBox.Show(ex.Message); } Tag: creating a hierarchical dataprovider Tag: 84777

    - 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?

    - How to submit bug report? How does one go about submitting a bug report to Microsoft for a defect in the .NET framework v1.1.4322? I was able to find a site for reporting bugs in the upcoming VisualStudio 2005 but nowhere could I find a way to submit bug reports for any other product. Is there a way to submit a bug report for v1.1 of the .NET framework or are any idiosyncrasies to be treated as features ;) Thanks Tag: creating a hierarchical dataprovider Tag: 84770

    - ngen.exe Where is kept native code at use of the utility ngen.exe? P.S. Sorry of my english Tag: creating a hierarchical dataprovider Tag: 84762

I have an existing object which can't be changed (generated from a
webservice)
I'd like to create a descendant class that would implement the necessary
interfaces to make it usable as a hierarchical data provider
the classes look smtn like:

class TMessage
{
public string MsgID;
public string InReplyTo;
public string Subject;
public TMessage[] Replies;
}

the relation is based on MsgID-InReplyTo

tnx
