    - Third time to ask this question,can anybody help me? 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!

    - EventType clr20r3 system.io.filenotfoundexception I start getting this exception when I moved my windows service to a Windows 2003 (32 bit running on AMD Opteron processors) server with .NET framework 2.0 . The EventLog says Event Type: Error Event Source: .NET Runtime 2.0 Error Reporting Event Category: None Event ID: 5000 Date: 2/22/2006 Time: 5:23:58 PM User: N/A Computer: UATDATASVCS01 Description: EventType clr20r3, P1 bo_winservicehost.exe, P2 1.0.0.0, P3 43fcd0f2, P4 mscorlib, P5 2.0.0.0, P6 4333ab80, P7 122f, P8 14, P9 system.io.filenotfoundexception, P10 NIL.

    - 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: ASP.NET 2.0 Remote Debugging 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: ASP.NET 2.0 Remote Debugging 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: ASP.NET 2.0 Remote Debugging 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.

    - How to install office version 11 in GAC A new PC with XP PRO and Office 2003 preloaded along with Framework 1.1.

    - Adding items to a ComboBox Currently, I'm doing this: Private Sub Populate() cboCategory.Items.Clear() cboSubcategory.Items.Clear() cboFileCategory.Items.Clear() cboSubcategory.Items.Add("Root") cboFileCategory.Items.Add("Root") For Each cCat In Categories cboCategory.Items.Add(cCat.Name) cboSubcategory.Items.Add(cCat.Name) cboFileCategory.Items.Add(cCat.Name) Next End Sub Now it seems like it would be more efficient to add the items to cboCategory, then use something like the AddRange method like this: Private Sub Populate() cboCategory.Items.Clear() cboSubcategory.Items.Clear() cboFileCategory.Items.Clear() cboSubcategory.Items.Add("Root") For Each cCat In Categories cboCategory.Items.Add(cCat.Name) Next cboSubcategory.Items.AddRange(cboCategory.Items) cboFileCategory.Items.AddRange(cboSubcategory.Items) End Sub Now of course, the above doesn't work; but is there a way to accomplish this? -- Alex C.

    - 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...

    - .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: ASP.NET 2.0 Remote Debugging Tag: 112149

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.

    - 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? Thanks in advance Weston Weems Tag: ASP.NET 2.0 Remote Debugging Tag: 112132

    - 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: ASP.NET 2.0 Remote Debugging 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.

    - ManagementOperationObserver and Get( observer ) The following illustrates a problem I have in another program ... however it only occurs on one in 5,000 remote machines. I suspect the cause of the problem lies with the remote machine ... but why doesn't my client time out with an exception ? The Get() method that initialises the asynchronous operation blocks for way too long (I've not seen it give up). Most of the time one will get an error of some sort, RPC not available, Access Denied, COM is stuffed, etc ... but when it hangs it's gone ... and it's repeatable against the machine ... but you have to find the right machine. Needless to say I've got a hugely multithreaded scanner trying to do all this scanning for real ... but when one of the remote machines block this initialisation ... then I'm stuffed. I've unsatisfactorily tried to set up another thread to maintain a timeout and abort the thread if it hangs too long during this method.

    - .NET Framework data provider for firebird Hi all, I installed Visual Studio 2005 standard and when I click on new connection (to connect to a SQL database) I get: "An unexpected error occurred in the .NET Framework data provider for firebird" I tried deinstalling VS2005 completely but still get this message. The firebird data provider is uninstalled long time ago (and I don't need this). How can I fix this? Where do I need to look? -- Thanks in advance, Stijn Verrept.

    - Cannot read in the keys from app.config (.NET 2.0) Hey guys, I'm stumped! :( I've been trying now for the last four days to read in the settings from an app.config file, but i've failed miserably, at what seemed like a simple task. I was trying to find out how the whole System.Configuration namespace is working. So, I made a simple C# windows application: One form, with a single textbox and and a simple "Load" button. this is what's in the Event handler: private void cmdLoad_Click( object sender, EventArgs e ) { // txtSettings is a textbox txtSettings.Text = System.Configuration.ConfigurationManager.AppSettings["MySetting"]; } BUT! when i click on the load button, the textbox does not get assigned any value! i mean, nada, zilttz, String.Empy, "" . I set up a breakpoing on the assignment above and i examined AppSettings[] . Turns out the AllKeys member has 0 (zero) dimensions. I was flabergasted :( Following is my App.settings file. I added this file by right clicking on the solution explorer, on the Project name (not the solution name) and then selecting "add new item -> Application Configuration file. Then, i went into Project Properties, clicked on the "Settings" tab and added three key/value pairs: MySetting, MyOtherSetting and MyOtherSetting. all three are at application level. <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="ConfigurationExample.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </sectionGroup> </configSections> <applicationSettings> <ConfigurationExample.Properties.Settings> <setting name="MySetting" serializeAs="String"> <value>HUHU</value> </setting> <setting name="MyOtherSetting" serializeAs="String"> <value>Tzimako alaka!</value> </setting> <setting name="MyLastSetting" serializeAs="String"> <value>ALL YOUR BASE</value> </setting> </ConfigurationExample.Properties.Settings> </applicationSettings> <startup> <supportedRuntime version="v2.0.50727" /> </startup> </configuration> Here are some questions: i've seen plenty of 1.1 example which ALL use appSettigns instead of applicationSettings. Keep in mind this is a 2.0 application file. And yes, appSettings WORKS GREAT if i add that section in manually. 1) is the <appSettings> section still required by the 2.0 framework in order to read in application settings data? 1.1) if yes, why isn't it explicitely created or why doesn't the preprocessor/compiler throw a warning about it? 1.2) Yes, i could use the <appSettings> section and do my job worderfully and get this over with. But that's not the point: If 2.0 has it's own way of retrieving application settings data, i should be able to use *THAT* instead of the depresiated 1.1 way, shouldn't I? Where am I fucking up? 2) requirePermission="false" <-- what does this setting do? 2.1) why does VS2k5 bitch about it not being declared? 2.2) do I need to declare it? 2.2.1) if yes, where and how? thanks guys, looking forward to your answers.

    - regexp - need help Hi, I want to parse string like "<number><trailing-char><title>" where <number> is a string containing digits and dots, <trailing-char> a whitespace or a semicolon and <title> any chars. I use a regexp (framework 1.1) to parse the strings. Here is the code: static Regex reNumSepTitle = new Regex(@"^(?<number>[\d-\.]+)([:\s])+(?<title>.*)$"); public static string ExtractTitle(string str) { string title = str.Trim(); m = reNumSepTitle.Match(title); if ( m.Success ) { return m.Result("${title}"); } return title; } When I call the method with "1.1:\tHeading", it returns "Heading". With "1.1.1.1:\tHeading", I get "\tHeading" (and the number part is '1.'). What's wrong ? Thanks. Tag: ASP.NET 2.0 Remote Debugging Tag: 112102

    - Socket works fine first time, fails second time Hello all I'm using a bit of very simple code to query a game server using a UDP packet. It works the fine time I run it but then when I run it again straight away it fails with.. "A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself" I reckon it's because the socket is not closing properly so is dtill open when I run it a second time. I assume this is down to lingeroption but I can't seem to set this to false as the syntax on msdn doesn't seem to work. Could someeone give me a hand with this please? My code is below...

    - Sending multicast messages from specific IP address Hi guys! I have several IP addresses defined on my PC (all bound to the same interface), and i need to send multicast messages from a specific address. Here's my code: void SendMsg( string localAddr, int localPort, string destAddr, int destPort, byte[] body ) { Socket sock = new Socket( AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp ); sock.Bind( new IPEndPoint( IPAddress.Parse( localAddr ), localPort ) ); sock.SendTo( body, new IPEndPoint( IPAddress.Parse( destAddr ), destPort ) ); sock.Close(); } The problem is - if "destAddr" contains a multicast address, than no matter what address i pass as "localAddr" parameters, the messages are always sent from the same address, randomly chosen from among the addresses defined on my PC. How can i bind my outgoing multicast messages to a particular address? Thanks! p.s.: i've seen suggestions to use "MulticastInterface" socket option in order to solve this problem. However, this only affects the interface, via which the messages are sent, but not the address (as i said, i have several addresses defined over one interface).

In Visual Studio 2003 this was'nt a problem.
I need to use the port number.

Does anybody have an idea to resolve this problem?
