    - calling java from DOTNET 2? how stable painfull? hi.. i have a java application server whish uses RMI as a delivery transport for it's apis (it's gets the command in XML but the underlying protocol needs to be RMI).. so i need to write an RMI CLIENT to this thing, and expose it microsoft land. at first we thought to have it exposed as web service and consume this service via dotnet dll. the dll would be given to desktop application developers which canno parse XML. then i was told i could expose it as JNI and have the dll access it directly. then the dll in dot net 2.0 would either be given to desktop developers or exposed as a web service in biztalk if web services are needed. btw can i do all of this with express edition versions?

    - .Net 2.0 Migration Strategy I work for a large organisation where we use .Net 1.1 as our sole development language. We have many frameworks and applications and web sites that are developed in .Net 1.1 These developments are by no means trivial, they are the result of an IT department of over 300 people and 2 years of development It is my responsibility to develop a strategy to move to .Net 2.0, this includes the existing applications, new developments, integration, QA, live and development environments Does any one have any experience in this (preferably at this scale) and can any one recommend any reading material that would help.

    - .NET 2.0 Polymorphic Configuration properties? Given: class AnimalElement : ConfigurationElement class Dog: AnimalElement { ... } class Cat: AnimalElement {...} class MyElement : ConfigurationElement { private const string animalProperty = "animal"; [ConfigurationProperty(animalProperty, IsRequired=true)] public AnimalElement Animal { get { return (AnimalElement)base[animalProperty]; } set { base[animalProperty] = value; } } } If Cat and Dog deinfe additional configuration properties, when I deserialize the config element, I'll get a ConfigurationErrorsException : "Unrecognized attribute..." for those additional attributes. I thouhgt I could put an attribute on my Animal property the same way XmlInclude used to work in .NET 1.1 but can`t find something similar. Is there a way to have polymorphic Configuration elements?

    - problems by consuming a web service via https Hi Together, Within my web service proxy programmed in .Net 2003/C++, I want to consume a service via https. The server certificate is a self built one. I thought it?s enough to install the certificate on my client computer, so that the certificate is available in the common key store. The access fails with an exception telling me, that the server can?t be trusted. The stack: at System.Net.HttpWebRequest.CheckFinalStatus() at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult) at System.Net.HttpWebRequest.GetRequestStream() at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at cg021179.ReiKoUploadWSService.isAlive() in c:\vc-projekte\testappupload\testreiko\cg021179.h:line 63 at main() in c:\vc-projekte\testappupload\testreiko\testreiko.cpp:line 25 Press any key to continue OK, then I must inform the SSL connection explicitly about the certificate by storing there an own built keystore, which contains the server certificate. So far so good. In java you have a tool building a keystore and you have the javax.net.ssl package for storing the keystore. That works! But what is the equivalent in .Net and C++? Or must be the solution in C++/.Net a quite different one? Thanks in advance for help.

    - Problem: Serializing with <NonSerialized> Does this attribute really work? I'm trying to "deep" serialize one of my objects which has a member variable pointing to a Form object. I don't want to serialize this form (and I know that I can't do this anyway because the Form class is not marked as Serializable). I try marking this member variable with the <NonSerialized> attribute, but the BinaryFormatter seems to be ignoring this attribute; It throws an exeption "Class frmReport {some info about the class here} can not be serialized, because it is not marked as Serializable" Is there any other way to prevent the serialization of a member variable that I don't know?

I want to run my ClickOne applications with command line arguments.I published my application by visual studio.net 2005,and my application url is http://localhost/myapplication/myapplication.application?myname=sunny. I have read the article about no-touch deployment applications : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnforms/html/winforms05152003.asp and followed his steps.My code is below: AppDomain domain = AppDomain.CurrentDomain; object obj = domain.GetData("APP_LAUNCH_URL"); string appLaunchUrl = (obj != null ? obj.ToString() : ""); But I can never get the value of appLaunchUrl.The method domain.GetData("APP_LAUNCH_URL") always returns null.I could not find any description about APP_LAUNCH_URL data variable in MSDN. When I copied myapplication.exe to IIS directory and run the application from the url of http://localhost/myapplication/myapplication.exe?myname=sunny , I could get the value as the article said. So why? And how can I get the value if I use the publish function of visual studio.net 2005 and run the application from the url: http://localhost/myapplication/myapplication.application?myname=sunny Thanks!

    - GetAssemblies SerializationException Hi, I am attempting to write a plugin framework, this in itself is not too difficult. What I would like to achieve is a plugin framework where the plugins can be updated on the fly. The problem that this presents is once the plugin files are loaded into an application domain the plugin files on the disk stay locked until that application domain is unloaded, even if no instances of the plugins are running. So to get around this the plugins must *only* be ever loaded into an application domain that can be unloaded. This is where it gets complicated. Normally I obtain a reference to an assembly using system.reflection.assembly.loadfrom and pass the filename as a parameter, however this loads it into the current application domain. After many frustrating days, trying to load an assembly into a specific app domain (ie not the current app domain), I have simplified my code right down to the following: Two subs from the class that manages the plugins, one lists the assemblies in an app domain, the other tries to load an assembly into an app domain. Public Overridable Sub ListAssembliesInDomain(ByVal Domain As System.AppDomain) Dim ContainedAssembly As System.Reflection.Assembly Dim Assemblies() As System.Reflection.Assembly Try Debug.WriteLine(vbCrLf & "Assemblies in Domain " & Domain.SetupInformation.ApplicationName) Assemblies = Domain.GetAssemblies() For Each ContainedAssembly In Assemblies Debug.WriteLine(ContainedAssembly.ToString & " " & ContainedAssembly.CodeBase) Next Debug.WriteLine("") Catch ex As Exception Debug.WriteLine(ex.ToString) End Try End Sub ' ListAssembliesInDomain Public Overridable Sub CheckForNewPlugins() Dim strAllFolders() As String Dim strPluginFolder As String Dim strAllFiles() As String Dim strPluginFile As String Try ' See if we need to initialize the plugin folders If strFolderPluginsNew = "" Or strFolderPluginsStore = "" Or strFolderPluginsRunning = "" Then ' Read the folder paths from the app.config file strFolderPluginsNew = System.Configuration.ConfigurationSettings.AppSettings(keyPluginsNew) strFolderPluginsStore = System.Configuration.ConfigurationSettings.AppSettings(keyPluginsStore) strFolderPluginsRunning = System.Configuration.ConfigurationSettings.AppSettings(keyPluginsRunning) ' Ensure that the paths exist and have a trailing \ Vigilant.Common.InitializeFolder(strFolderPluginsNew) Vigilant.Common.InitializeFolder(strFolderPluginsStore) Vigilant.Common.InitializeFolder(strFolderPluginsRunning) End If ' Get the sub folders of the new plugin folder strAllFolders = System.IO.Directory.GetDirectories(strFolderPluginsNew) ' Check that we have some sub folders of the new plugin folder If Not strAllFolders Is Nothing Then ' Loop through each sub folder For Each strPluginFolder In strAllFolders ' Create an application domain that we can load any plugins ' found in this folder into, once we are finished we can ' unload the application domain and the plugin files will ' no longer be locked. Once they are unlocked we can ' move them to the appropriate location. objPluginDomainTemp = System.AppDomain.CreateDomain("Temp Plugin Domain", AppDomain.CurrentDomain.Evidence, AppDomain.CurrentDomain.SetupInformation) objPluginDomainTemp.AppendPrivatePath(strPluginFolder) ' Get a list of all the exe's in this plugin folder strAllFiles = System.IO.Directory.GetFiles(strPluginFolder, "*.exe") ' Check that we found some exe's in this plugin folder If Not strAllFiles Is Nothing Then ' Loop through the list of exe's in the plugin folder For Each strPluginFile In strAllFiles ' For debugging purposes list the assemblies that are ' currently loaded in the temporary plugin app domain ListAssembliesInDomain(objPluginDomainTemp) Try ' Attempt to execute the assembly within the temp plugin app domain ' ' NB: The aim of this is just to load the assembly into the temp plugin app domain ' other ways have been tried, but are less straight forwards, so during the ' process of trying to track this bug down, I reached the conclusion that ' the most straight forwards way to load the assembly into a different app domain ' was by causing it to be executed. objPluginDomainTemp.ExecuteAssembly(strPluginFile, objPluginDomainTemp.Evidence) Catch ex As Exception Debug.WriteLine(ex.ToString) End Try ' For debugging purposes, we want to now see if the assembly ' we executed is now listed in the temp plugin app domain ' ' It's within this call that an exception is thrown ListAssembliesInDomain(objPluginDomainTemp) Next End If If Not objPluginDomainTemp Is Nothing Then AppDomain.Unload(objPluginDomainTemp) End If Next End If Catch ex As Exception Debug.WriteLine(ex.ToString) End Try End Sub ' CheckForNewPlugins The Plugin File is just a console app with the following code Module Module1 Sub Main() Debug.WriteLine("Plugin Executed") End Sub End Module I've got dbmon running and get the following debug output: 3600: Assemblies in Domain aab4bae7 3600: mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 file:///c:/windows/microsoft.net/framework/v1.1.4322/mscorlib.dll 3600: 3600: Plugin Executed 3600: Assemblies in Domain aab4bae7 3600: System.Runtime.Serialization.SerializationException: Insufficient state to deserialize the object.

    - Copy constructor? Hi, I have created a class adding some Functionality to a generic class and derived it from that: class MyTypedClass : MyGenericClass {} Within a class library project, all functions work with the generic version, but in my Web Application project I'm dealing with the derived version (basically adding type to the generic version). But the following doesn't seem to be possible: MyTypedClass mtc = (MyTypedClass)(new MyGenericClass()); Is it possible to create kind of a copy constructor in C#, like class MyTypedClass : MyGenericClass { public MyTypedClass(MyGenericClass mgc) : base(mgc) {} } TIA, Axel Dahmen Tag: Plugin framework sample with AppDomain shadowcopy functionality Tag: 112213

    - deploying security policy in AD (caspol?) I got an .NET app, got it signed with a strong name, and now would like to give this app (better, every app signed with this strong name) full rights in my entire network. So I am looking for a way to set once, on my windows server 2003, full rights for all apps signed with this special strong name. Well, there is an 'enterprise' setting on caspol, but I can't get this setting propagated on the AD network. I thought this should be a common problem, but I can't find no solution other then making a batch and starting it on every comp more or less by hand (since only admins can set machine or enterprise rights logon scripts could only be used for user rights). Any ideas? Sam Tag: Plugin framework sample with AppDomain shadowcopy functionality Tag: 112202

    - DPAPI via impersonation I'm trying to use DPAPI via impersonation. (.Net 2.0) * DPAPI works fine * impersonation works fine (via PInvoke) However, when I try to use DPAPI after impersonation, it fails. The failure appears to be that the profile is not loaded. I get: System.Security.Cryptography.CryptographicException : The system cannot find the file specified. So. I use PInvoke to load the users profile. That fails with an access violation. So. Again using PInvoke, I add SE_BACK_PRIVILEGE and SE_RESTORE_PRIVILEGE t the process token, before impersonation. Still an access violation on the profile load. If I attempt to add the token privileges after impersonation, the attempt fails with an access violation. Does anybody know the secret sauce to using DPAPI under impersonation? This is not for ASP.Net and this part of the app could run with admin privileges if needed. Thanks! Tag: Plugin framework sample with AppDomain shadowcopy functionality Tag: 112201

    - Get Assembly of Calling Thread or Object? Does anyone know how to get the assembly associated with a particular thread? I'm creating a generic Factory class to create types based on config file parameters. I would like to use the calling object's assembly if it isn't specified in the config value. I know how to get the current executing assembly, but I don't know how to find the assembly associated with the calling thread, which will always be a seperate assembly. Or, if using the thread is the wrong approach, is there a better/different way to identify the assembly of the object that called my Factory.CreateObject method? Thanks in advance.

    - Strong name validation failed after calling a .Net Exe from ASP Hi! I have a severe problem with my ASP web application. The ASP Site is built to run a .Net application (on command line mode) synchronously. I've tried to run the .Net exe on the server for many times, and it always returned without an error and worked correctly. Within the ASP page, I call the .Net application by the WScript.Shell object, in synchronous mode. Unfortunately the shell call returns with an error, the eventlog entry shows a "Strong name validation failed" error for the .Net application (which runs without problems, if started local). The server is a Windows 2000 server with IIS 5.0. This whole workflow already works with an XP server!! And now I should try making it run on the 2000 platform. btw> I checked all known to me security options. The IUSR even has administrator rights...

    - Good Cheap Installation Software?? Hi, Was wondering anybody could help? I'm looking an application to help deploy my Windows Form application. I've been using the built in installer in VS.NET 2005, but I want to package all the files up into one exe (this includes the prerequisites!). So that my users only have to download one exe and not have to worry about downloading a zip and then unzipping it.. Any ideas?

    - .NET based services not starting reliably: ServiceController.Start() method We're using the ServiceController class provided by the .NET Framework, programming in C#. We are using the Start() method to start a service from another service. This works fine most of the time, but occasionally after a system startup (where the service doing the starting of the other is automatically started by Windows XP) the ServiceController's Start() method fails to start the other service. It is probably throwing an InvalidOperationException in these cases (we know it is in some cases). Is there any way to tell why Windows cannot start the service, and are there known problems with the reliability of the Start() method? It works most of the time, but occasionally after unsealing the XP OS, or after a restart, this fails. We're trying retries of calls to the Start() method, but after 3 retries it still fails inexplicably. We need to find out if: 1.. this is a known problem 2.. how long does it wait, and is this wait time adequate? 3.. can this happen if one of the services upon which the service being started depends takes too long to start? We are quite sure the actual service being started takes almost no time to execute its two lines that consist of starting a worker thread in its OnStart() method. 4.. is there some reason this would only occur after an unseal or system restart (that's the only time we see it)? 5.. there are any known fixes or workarounds to this problem Tag: Plugin framework sample with AppDomain shadowcopy functionality Tag: 112149

    - Thread Detach Notification Hi, Is there a way in managed .NET to get a notification as to when a thread exits normally? In the unmanaged world, you could handle the DLL_THREAD_DETACH in DllMain( ), but I couldn't find anything in .NET that gives you this notification. I could iterate through the list of available threads in the process to find if a particular thread Id is still alive, but that would not work for my implemenation. Thanks.

The problem is that my main application runs few DLLs some need to run on framework 1.1 and some on 2.0 - so I cant specify on the exe.config to run on 1.1 (<supportedRuntime>) - b.c then other dlls wont run well.

    - AppDomain Shadow copy and plugin framework models PLEASE HELP! =0 Ok, I've been quite successful on my own building a plugin framework that appears to be working quite well. I can manually unload/reload etc, however, the original app domain is retaining a lock on the shadowcopied assembly. I've done a fair ammount of research before resorting to this. My model is like the following. ------------- -------------- --------------- PluginLoader RemoteLoader MyPlugin:IPlugin ------------- -------------- --------------- plugincollection LoadPlugins LoadPlugins Basically, I instantiate a plugin loader which creates a new appdomain with setup info for shadow copying etc. It instantiates remoteloader with a plugin path. LoadPlugins on PluginLoader calls LoadPlugins which returns a IPluginCollection which is a collection of instantiated types etc. I beleive my problem is that because I set a local var in my app to return value from pluginLoader.LoadPlugins that its hanging on to the original files. How could I remedy this situation? I'd like to be able to delete/overwrite dlls on the fly. How do you guys do it?

    - Need to install 1.1, already have 2.0 I have a dll that a co-worker wrote which needs .NET 1.1 to work. The server I am installing it on already has 2.0, probably installed when I put SQL Server 2005 there. I cannot make this dll work on any machine that has .NET 2.0 on it. However, if I go into IIS and tell my default web site (which uses this dll) to point to .NET 1.1, it works. I don't have the time right now to look into why it works in 1.1 and not 2.0. What I'd like to do is have 1.1 on this server. However, for some reason, 1.1 doesn't show up in the IIS dropdown; only 2.0 does. When I try to install 1.1 from an exe I downloaded some time ago. It won't let me install 1.1. Is there any way around this? Tag: Plugin framework sample with AppDomain shadowcopy functionality Tag: 112130

    - FTPWebRequest Fails on Some FTP Sites I posted this problem a week ago, and received no response, so here it is again... While using FTPWebRequest, I have found at least one FTP site where this function fails. The URI I am using is ftp://nssdca.gsfc.nasa.gov/md_doc/app_a.doc This NASA ftp site is available through anonymous log in, and other FTP clients, including Internet Explorer using FTP protocols, download the file just fine. As the capture below shows, when FTPWebRequest sends PWD, it receives ANON_DIR:[000000] from the ftp site. Then when FTPWebRequest sends CWD ANON_DIR:[000000]/md_doc/ it receives an error of 550, then it gives up and closes the connection. Any advice on this would be helpful.

    - Can one EXE double as Windows Forms app and as Windows Service? I have a Windows service application with a public class that inherits from System.ServiceProcess.ServiceBase Is it possible to modify this application so that it still is a Windows service but on the other hand can be started just as if it were a standard Windows Forms application (e.g. by double clicking the .exe file)? Background: I would like to deliver a .exe file to the user who then double clicks it. The application then offers a UI with options to install itself as service. For diagnostic purposes it also would be nice to tell the user "Shut down that service and then double click the .exe" to get an application with UI.

say that I'm quite baffled. I would REALLY like to be able to implement
a shadow copy routine so I can load my plugins into an appdomain, and
delete/add/overwrite etc...

I just need a small sample, I've got everything working, except that
even though I've stuck everything in new appdomain etc, with
shadowcopyfiles = "true", it more or less ignores that.

THe grapher example does exactly what I want, but its way more complex
than it needs to be (I just want the basics, hello world in a text
editor type simple)

Does ANYONE have any recommended reading material?
