Does anyone know how to create the parameter description that appears below the parameter autocomplete popup when a method in the helper class is being used in Visual Studio? Is there a meta tag for this? At the moment the parameter list appears the yellow popup window but no parameter description is displayed below. Any tips greatly apprecated.

    - Dynamic menus - Collapsing and Expanding Hello All, I need to create a menu list on a page that will expand when clicked and stay expanded until clicked again. Actually, I want it to look just like the menus on the Microsoft Newsgroup homepage - with a plus sign to expand and a minus sign to collapse the menu. Also, I want to be able to add new sub-menu items in a single place (some kind of admin interface) and have them instantly be available when the parent menu is expanded. Does anyone have any ideas on how to make this a reality? Help greatly appreciated. Thank you, Benno Tag: DTD to xml Tag: 69560

    - Passing parameters to new AppDomain Hello, Is there a way to pass some data to domain created by AppDomain.CreateDomain so they will be available for custom configuration section handlers? As I can understand the custom handlers are invoked on first access to configuration section (i.e. not inside CreateDomain) so I can call newDomain.SetData() to pass parameters and then creates objects. Can I rely on such behavior of handlers in nearest future version of .NET framework? -- Best regards, Vladimir Tag: DTD to xml Tag: 69555

    - IPAddress.Address is negative Hello, I perform a ping using the IcmpSendEcho Function from iphlpapi: <DllImport("iphlpapi")> _ Private Shared Function IcmpSendEcho(ByVal IcmpHandle As IntPtr, ByVal DestinationAddress As System.UInt32, ByVal RequestData() As Byte, ByVal RequestSize As Integer, ByVal RequestOptions As IntPtr, ByVal ReplyBuffer() As Byte, ByVal ReplySize As Int32, ByVal Timeout As Int32) As System.UInt32 This Function requires a Destination Adress as an unsigned Int32. I get it from the IPAddress.Address Object. Public Structure PingOptions Dim IPAdress As IPAddress Dim TimeOUT As Integer End Structure dim opt as PingOptions opt.IPAdress = IPAddress.Parse("192.168.1.128") ' Adresses bigger then A.B.C.127, have a negative adress value !!! ipaddr = System.UInt32.Parse(opt.IPAdress.Address) ' and couse exception here Dim ret As System.UInt32 'but i need an unsigned int here in the second parameter ret = IcmpSendEcho(h, opt.ipaddr, RequestData, CInt(RequestData.Length), IntPtr.Zero, reply._Data, reply._Data.Length, opt.TimeOUT) The Problem is that for IPAdresses, where the last Byte is bigger then 127. the generated Long Value for Adress is negative and the Parse Method to the uint32 couses an exception. Or should i declare the DestinationAdress as Long in the IcmpSendEcho and put in IPAdress.Address value directly. My assumption is that the Address value is created in the correct bitformat but becouse the CF is declaring it as a long it is interpreted negative. Or how else to get the correct Long Value from IPAdress.Address ?

    - Activating an instance of a class in a referenced assembly I'm trying to use Type.GetType() so I can create an instance of a class I have defined in a different, yet referenced, assembly but it doesn't seem to be able to find the type. How can I get a type object of a class in another assembly? For example, if you reference the System.Xml namespace, try this Type importType = Type.GetType("System.Xml.XmlException", true); It will throw an exception. I see that there is also the GetTypeFromProgID() and GetTypeFromCLSID() methods in the Type class but these seem to only apply to registered COM objects. Tag: DTD to xml Tag: 69548

    - HKEY_LOCAL_MACHINE - Setting Read Only Permissions I have a .NET winforms application that requires read access to a custom key stored in HLM. Installation of application will create a key in HLM programmatically. This is no problem since only admins will be performing install. However, the application will be run by non-admins. The key created will require read only access for these non-admin users. Is there a way to programmatically set permissions to the key? I'd like to prevent having to go into regedt32 to set the permissions for every desktop running the application. I've tried several of the coding examples in the RegistryPermissions class with no luck. I'm certain it is because I am not correctly using the class or I am using the incorrect class. Any tips would be greatly appreciated. Tag: DTD to xml Tag: 69538

    - COM Class Vs. Sn.exe, Gacutil.exe and Regasm.exe There seems to be two ways of creating a COM in .NET 1) Select the COM Class template 2) Create a class and then use Sn.exe, Gacutil.exe, and Regasm.exe to assign the assembly to GAC and COM to registry I know that COM Class option is a lot easier to use. However, is there any drawbacks from using this instead of option two? Is it suggested that you rather use option 2) even it's a lot more tedious Thanks for info. Tag: DTD to xml Tag: 69532

    - Should I drop Library activated Serviced Component from COM+ when the interface changes? I would like to understand better what happens when a public interface of a serviced component changes Suppose that I have a library activated serviced component. Suppose that I lock its version number ([assembly: AssemblyVersion("1.0.0")]) and installed the component into COM+ catalog (via regsvcs or just by running a client that uses it) Now, suppose that I change the existing method or add a new method in the component It appears that everything continues to run fine afer the change I am not sure, though, if this is the way to do it. I always drop the component from COM+ catalog when the interface changes Question is, do I need to?

    - "Assert failed" under Windows 98 Hi, I've developped a Window Form application with .NET that runs perfectly well under Windows 2000, XP and 2003. However, when i run it under Windows 98SE, i get the following error *after* the application has been closed (MyApp is the name of my executable): "Assert failed - copied to MyApp.err" File Refcount.cpp, line 652 Build: v7.10 (07/08/02 11:27:29) Expression: ! (i == idata->tdmap.end()) The strange thing is that it doesn't happens when my code is executing but sometime after the execution is finished, probably somewhere in the framework itself when it's cleaning up after a program has been closed. If somebody has a clue of what's happening here, please help! i have no idea where to look as the error comes from outside my code:-( And this just prevents me from distributing my application to Windows 98 users which was one of my targeted platform.

The same classes in the 1.0 framework could be viewed just fine using the Quick Watch or Immediate window.

    - CCW overheads To whom it may concern: We are in the process of deciding on a technology to go with - .NET or VB6. The project entails interfacing with Classic COM objects written in C++ on another system. I've suggested that we write our custom code using the .NET framework and expose it to the classic COM objects using COM Callable Wrapper. Others suggest that we should go with VB6 (Classic COM to COM communications)so as to circumvent any form of overhead that could be incurred during the CCWs "wrapping" process. Any form of feedback is much appreciated. Best, Jack Sparrow Tag: DTD to xml Tag: 69508

    - XmlSerializer / Temp directory / System shutdown My application has a settings class that is serialized to save and deserialized to load. I'm having a problem where i catch the WM_QUERYENDSESSION event via WinProc to save my application's settings when a user logs out, reboots or shuts down the system. The behavior of XmlSerializer is that it creates temporary dll's to do the (de)serialization in the system's temp directory. The behavior of windows on a system shutdown is to purge these temporary files from the system's temp directory. The problem i'm having is that i am unable to serialize my settings class when the system is shutting down, because windows is purging these temporary files. Is there a way to control the directory where the XmlSerializer creates the temporary files (other than changing the TEMP environmental variable, which isn't an option for me), or is there another means of serialization i can use which bypasses the temporary file creation step? My settings class has hundreds (potentially thousands) of things getting saved to a file. Manually serializing/deserializing would be a real pain that i am hoping i can avoid. This seems to be a big flaw in the .net xmlserialization implementation. :( Tag: DTD to xml Tag: 69507

    - AssemblyVersion - what if I want to enter DLL Hell? The title is a joke, clearly I don't want DLL Hell. However, I am curious if there is a way to follow the shared DLL model of the past using the GAC. Specificially - I have ten seperate console applications, lets call them 'ConsoleApp1.exe' through 'ConsoleApp10.exe' which each depend on a single class library named 'Utility.dll' which is strongly named and installed in the GAC, v1.0.0.1 I regularly develop performance improvments to 'Utility.dll' which I want all the console apps to benefit from. Over time, i develop v1.0.0.2 , v1.0.0.3 all the way to v1.0.0.9 - each time I wish to deploy the updated library and have all of the console apps use it. Is there any way for me to install the new class library in the GAC and have it used by all console apps WITHOUT using a Publisher Policy File (i.e., is there any way to mark the new library as "compatible" and therefor the console apps will use the newer version).

To the design surface of MyComponent I've dragged an SqlConnection object, an SqlCommand object, and an SqlDataAdapter object and linked these items together appropriately. My question is this: Why are these Sql components not added to the list of components contained by MyComponent? (These objects are not added to the private "components" member of MyComponent.) Is there a technical reason for this or is it just a bug in the designer? Is there any way I can get the Designer to add these items to the collection automatically, without having to hand-code it myself? Thanks, -Dave Tag: DTD to xml Tag: 69503

    - Accessing the Download Cache I have an application that uses Assembly.LoadFrom to successfully instantiate a dynamic assembly that lives on a web server. For architectural reasons I would rather not create a reference to the external assembly. The assembly, and all other assemblies that it is dependent upon, is placed into the local download class when the application is started for the first time, and the computer has an empty download cache. This is verified by running: > gacutil -ldl Microsoft (R) .NET Global Assembly Cache Utility. Version 1.0.3705.0 Copyright (C) Microsoft Corporation 1998-2001. All rights reserved. The cache of downloaded files contains the following entries: common, Version=1.0.0.35263, Culture=neutral, PublicKeyToken=6a8177ec3babee2f, Custom=null etc. The URL that the assemblies came from is: http://localhost:8082/client/client.dll Now, I unplug my laptop from the network, and I still expect the application to run, using the latest assembly. I have tried every combination of: Assembly.Load, Assembly.LoadFrom, Assembly.LoadWithPartialName with and without using Evidence. I cannot load the assembly that is sitting in the download cache. So, here are my questions: 1. Is it possible to pragmatically access the download cache? How? 2. Can you pragmatically add an assembly to the GAC? 3. Is there a better way to do this?

    - NullReferenceException Message Feature Request I'm guessing that NullReferenceExceptions are by far the most common exceptions thrown in .net. Why not add the type of the reference to the message? Have it say something like: Object reference of type 'string' not set to an instance of an object. This would really help when trying to figure out where the null reference is happening. I've just spent the last two days finding a null reference that happens very intermittently. Having the type would have saved me many hours. In addition to just the type, you might be able to use reflection to give a property name or variable name.

    - PerformanceCounterCategory woes Hello all, This is a long post but I'd better provide all the details from the outset to prevent cluttering the NGs with clarifications. I also apologize for cross-posting, I am just not sure what area the root of the problem belongs to. So, I am currently trying to resolve a very puzzling problem with the PerformanceCounterCategory class. Suppose we have the following code snippet: <codeSnippet> bool ok = true; if (!PerformanceCounterCategory.Exists("My category")) { ok = false; } if (ok && !PerformanceCounterCategory.CounterExists( "Counter Name 1", "My category")) { ok = false; } if (ok && !PerformanceCounterCategory.CounterExists( "Counter Name 2", "My category")) { ok = false; } </codeSnippet> Most of the time, the code above works OK. Sometimes, however, it chokes on the CounterExists method call - an InvalidOperationException is thrown with Message saying "Category does not exist". The stack trace points to a PerformanceCounterLib class which seems to be not documented. It's strange, isn't it - the Exists method has just reported the category *does* exist. Well, now the symptoms: a) It is an ASP .NET application b) The ASPNET user has been granted permissions to the appropriate registry keys (WindowsNT\PerfLib and CurrentControlSet\Services), but still remains in the group it has been added to by the installer. c) If the machine is restarted (sometimes it is enough to restart IIS), the problem usually goes away. d) It is very hard to reproduce the problem. We have observed it for several months, but still haven't figured out the pattern. I have searched Google newsgroup archive, KB, MVP-level KB, the Web - but to no avail. The only post I found on the Russian GotDotNet forum suggested to swap the order of some lines in code, but this is hardly a reliable solution. Any help would be greatly appreciated. -- Dmitriy Lapshin [C# / .NET MVP] X-Unity Test Studio http://www.x-unity.net/teststudio.aspx Bring the power of unit testing to VS .NET IDE -- Dmitriy Lapshin [C# / .NET MVP] X-Unity Test Studio http://www.x-unity.net/teststudio.aspx Bring the power of unit testing to VS .NET IDE Tag: DTD to xml Tag: 69443

    - Application termination in debugger Hi, I've a component which seems not to terminate correctly. In VS.NET I start a new instance to debug the component within a simple winform application. The program is up and running. If I hit the "Stop Debugger" icon in vs.net the process terminates as expected. If I close the application using "Application.Exit()" the window disappears but the process will still be active in task manager and the debugger doesn't stop. I found that the dispose methods are called and the end of the main method is reached as expected, no exception was thrown. The component used COM/Interop and P/Invoke, but I have had no problems using this so far. Has anybody any idea how to proceed from here or even how to debug into the problem. What exactly happens (or should happen) on Application.Exit()? If I run the applicatin outside of VS.NET, e.g. simply double click the exe file, it starts and terminates as expected (it disappears immediately from task manager). Is this a VS.NET known bug? Thanks for your attention, Joerg Tag: DTD to xml Tag: 69438

I'd like to use 'xsd.exe' to generate a set of classes so that I can serialize XML for a
given DTD

However, I don't believe 'xsd.exe' reads DTD's. So is there an easy way to conver
a DTD to an XML schema, or go directly from a DTD to a .NET code base that ca
be serialized

Thanks

XMLSPY can do this, but it's not free.
