    - Memory I have a C# .NET Console application which, in spite of garbage collection and the fact that I'm pretty sure I have no lingering references, slowly takes more and more memory as it runs (as shown in the task manager) until it slows to a crawl. Can anyone suggest a good profiler that I might use to discover what this memory's being allocated to? b.t.w. the app uses a database, does other filesystem operations, and may call into a c++ library occasionally (the HTML Tidy libaray, for those of you familiar with it... actually NTidy, the .NET wrapper.) Thanks, Andrew Tag: IE Hosting problem Tag: 88529

    - Diagnostics.Process doesn't return argument info I'm trying to use Diagnostics.Process to get info about currently running processes. If I start Notepad with a parameter like: Notepad x1.txt, I then get the currently running processes, and the Notepad process doesn't have any arguments listed in the StartInfo object. Does anyone how to get this info? Thanks, Steve Tag: IE Hosting problem Tag: 88528

    - Using Trace class Hi all, I have a .NET object exposed to a COM (VB6) application. When the application calls the .NET methods, I'd like to use Trace.WriteLineIf() to log trace info into an event log. Usually with ASP.NET application, one can control the TraceLevel of a TraceSwitch in web.config, and for WindowsForms or console applications, in App.config file. However, in this case I only have a shared library (assembly). How would I control the trace level in this scenario? Also I'm thinking of using Trace.WriteLineIf(mySwithch.TraceError, "error: ....") instead of calling EventLog.WriteEntry(...., EventLogEntryType.Error). The problem is that all events are logged as type "Information". Is there a way to tell Trace class to log an event as type "Error"? Thanks, -Oleg. Tag: IE Hosting problem Tag: 88526

    - error while hosting asp.net in managed c++ dll. I have a pluggable asp.net hosting provider which uses a cassini-based http listener if the platform is win2k or xp (non sp2), and uses a HTTPAPI (http.sys) based listener in a managed c++ dll if the platform in win2k3 or XPsp2. The solution works perfectly when the HttpWorkerRequest is implemented in a c# dll. When it is implemented in the managed c++ dll, I always get the following error: The application's configuration files must contain 'trust' section. Stepping through the code, I can see that asp.net receives my HttpWorkerRequest and properly maps the directory to where I have my web.config. Adding a trust section doesn't help for any values in it. It's not a permissions problem because I've not only given the file full control for Everyone, but when debugging I can see that the process is in fact running as an administrator. Could anyone help? -EP Tag: IE Hosting problem Tag: 88518

    - Unable to Impersonate user exception Hi, I would like to know the possible causes for the security exception " Unable to impersonate user" I have .netframework 1.1 on my machine. The scenario is as follows I have multiple worker threads running and which are impersonating. These threads are not spawned from an impersonated thread. through some of the postings I got to know that the possible cause can be 1. A main thread and a worker thread impersonating at the same time.- this is not happenig in my case 2. If the token used for impersonation is not a primary token.- I am using a duplicate Token to using DuplicateToken. Are there any other reasons that cause this problem. Thanks, Praisy.

    - Unexpected interaction of ValueType, Reflection and ref parameter I posted a question yesterday under the Subject "How can I copy a value type dynamically without knowing the type". Unfortunately, I did not tie the problem down to a real code example. After further investigation, though, I have managed to create a real example of the problem. My original question was how to create a copy of a Value Type dynamically so that it does a copy-by-value rather than copying a reference to the same boxed object. The answer given was simply to use the code shown below as 'CopyValueType', which worked in all of the simple examples shown. This confused me for a while until I discovered that the code which was subsequently manipulating the variable was using reflection to call a method and passing this variable as a ref parameter. This combination shows the problem, as demonstrated in the code below. static void Main() { int i = 0; Process(i); } private static ValueType CopyValueType(ValueType i) { return i; } private static void Process(ValueType i) { ValueType j = CopyValueType(i); Console.WriteLine("Original i = " + i.ToString()); Console.WriteLine("Original j = " + j.ToString()); OtherCode(j); Console.WriteLine("i is now = " + i.ToString()); Console.WriteLine("j is now = " + j.ToString()); Console.Read(); } private static void OtherCode(ValueType x) { MethodInfo method = typeof(Class1).GetMethod("Update", BindingFlags.Static | BindingFlags.NonPublic); method.Invoke(null, new object[] { x }); } private static void Update(ref int v) { v = 1; } If you execute this, you get: Original i = 0 Original j = 0 i is now = 1 j is now = 1 As you can see, both i and j have been modified by the call to Update via reflection - so the return value from 'CopyValueType' is clearly not a completely separate copy from the input parameter, but must still be a reference to the same original variable. My requirement is to be able to implement the 'Process' method above without having control of the input parameter (except that it is a ValueType) and without knowing what code is in the 'OtherCode' method. The requirement is simply to make a copy of the input variable and pass it on in such a way that the subsequent code cannot modify the original variable. So I think I'm back to my original need for an implementation of 'CopyValueType' that creates a copy of the input parameter rather than a reference to it. Any help would be greatly appreciated.

    - Threads, lock, many readers, one exclusive writer Hi, I am so far familiar with the C# lock keyword, which I understand prevents any other thread from entering the portion of code which is locked, assuming you are locking the same object instance. I have a cache of data which initially I locked when I write to it, and I locked the same object for any reading. But this will soon become a performance issue, as many threads need to read it concurrently. What is the optimal approach? thanks! Tim Tag: IE Hosting problem Tag: 88498

    - Netscape browser caching problem I wrote a Web Application that works the way it should on IE but has a little bit of problems on Netscape Navigator. When using IE, clicking the back button will cause the browser to redisplay the current page not allowing my database to get corrupted by doing the following. Response.Cache.SetCacheability(HttpCacheability.NoCache); Always Response.Redirect(myself) on any event. In Page_Load() check it the current is the PostBack page and if not, Response.Redirect(current page). By doing the above, IE works perfectly and backups never occur. However, it appears that Netscape Navigator does not purge the browsers cache so I don't get a PostBack to the page that I backed up to allow me to redirect it back to the current page. This doesn't cause any database corruption problems because as soon as someone enters data in the backed up page and issue a post, the backup page will receive the post and realize that someone is operating on the wrong page and will redirect back to the current page restoring the application to the correct state. However it's messy if someone uses the back button when using Netscape Navigator. I've tried every possible fix that I could find on the Internet including Meta tags and javascript but Netscape Navigator will not issue me a postback when the back button is clicked. Firefox also does the same thing. Anyone know how to disable cache in the Netscape Navigator? Tag: IE Hosting problem Tag: 88493

And I ran into this problem today: When calling one of the sqlite3 functions, the following exception occurs originating from mscorlib.dll: "Resource lookup failed - infinite recursion detected. Resource name: Arg_NullReferenceException" The wierd part is, this function that triggers the exception is called hundreds of times before and works with no problems. And about half the time, the problem won't occur at all, the other half, the above exception will occur( if in debug mode), or if in release mode, the application will simply hang. Any suggestions?

The scenario is as follows: The class MANCombobBox inherits from ComboBox and implements the interface IReportDataSource. This works: Control c = new MANComboBox(); //MANComboBox inherits from ComboBox and implements the interface IReportDataSource MessageBox.Show( (c is IReportDataSource).ToString() ); //This returns/displays true Here we have the problem: Assembly asm = Assembly.LoadFile("LookupControls.dll"); //loads the dll which contains the MANComboBox control Control control = (Control) asm.CreateInstance(fullControlName); //Pointing with the mouse onto control, the IDE tells me, that control contains something of type MANComboBox MessageBox.Show( (control is MAN.Framework.Win.MANReportLookupControls.MANComboBox).ToString() ); //returns false Intellisense even shows me the methods of the implemented interface IReportDataSource but during runtime an invalid cast exception is thrown.

    - Fully trust digitally signed assemblies Hello all, Im posting this question to this forum as well hoping to find an answer. I had previously posted to the .net security forum but have not gotten a response yet. Here is the problem. I have an isolated network where I am not connected to the web. I'm using some digitally signed assemblies in my .net application and am running the application from my local drive. Im signed in as admin to the machine. With Windows 2k, sp4 and .net 1.1. I notice unusually long loading times when using the digitally signed assemblies (10+ seconds) and I can see that whenever I launch the app, some network activity is generated. There are some queries to crl.thawte.com made and the form loads up. Normal loading time is supposed to be about 1 second. I have tried using the .net config tool to give full trust to the publisher, the assembly and so on. But it seems like the .net framework always like to walk the certificate chain everytime and in doing so needs to be connected to the net. Otherwise, the timeouts just end up delaying the loading of the assembly. If I am running the app from a fully trusted location, why would the framework need to keep validating the certificate and look up the crl? I though this would only happen if I'm downloading the app from a url link or running it from a network. How do I fully trust a publisher so that I do not get these delays? Can I somehow force the framework to reduce its timeouts? Or to not check for crl's online? Can I install something locally on the system so that it does not require network access to load the speedy fashion? Is network access a prerequisite to using digitally signed assemblies ? Has anyone else run into these problems before? Thanks Tag: IE Hosting problem Tag: 88472

    - http header Proxy-Connection not set to Keep-Alive by setting HttpWebRequest.KeepAlive to true Hi All, I'm trying to track down why my application built on HttpWebRequest and HttpWebResponse fails to successfully log onto and access some web resourses, while IE does so without problem. The sequence of requests and responses culminates in a page for IE but in an exception for my application of type 'System.Net.WebException': The remote server returned an error: (504) Gateway Timeout. Using an http sniffer (Ethereal) I can see that IE is setting the http request header "Proxy-Connection" to "Keep-Alive" while my application does not send that header. Yet for each new request I make I include the line of code: request.KeepAlive = true; Any pointers as to why setting my HttpWebRequest's KeepAlive property to true is not resulting in the "Proxy-Connection" header being set to "Keep-Alive"?

    - How can I copy a value type dynamically without knowing the type. I need to be able to dynamically create a new copy of a value type without knowing the type at compile time. i.e. I need to be able to write a method such as: ValueType MyMethod(ValueType data) { return copy-of-data; } which returns a new ValueType that is a copy of the 'data' parameter. Returning the 'data' parameter itself is no good as it returns the boxed value which is passed into the method, and therefore references the original variable. I would have thought that there would be a simple way to do this, but I can't think of it. Can anyone give me an idea how to do this? Robert. Tag: IE Hosting problem Tag: 88462

    - Single instance application using remoting errors Hi, I am experiencing an issue with remoting trying to implement a single instance app behaviour required for our application. I am using the MS best practice recommended solution of using Remoting and Mutexes to provide this behaviour. In simple terms this is the process: 1. The application's Main() method creates an instance of a SingleInstanceHandeler class (code attached). 2. The Main() method then calls the Run method on this class. 3. The Run method creates a unique key for this application (user and workstation specific also) and attempts to lock a Mutex for this key. If it succeeds this is the first instance. If it fails it is not the first instance. 4. If this is the first instance a remotable version of the SingleInstanceHandeler is registered and a channel created to listen for requests. The OnStartup event is then fired, passing the command line arguments, which is handled by the class in which the application's Main method is contained. 5. If this is a second instance, a connection to the remoted version of SingleInstanceHandeler is created and the OnStartUp event fired on the "remote" object passing the command line arguments. The second instance then exits. Now this works great for a short period of time. However, after some time (maybe 5 minutes) the remoting channel stops "listening" (my best guess as to the problem). This means that any second instance fails to create a connection to it and throws an exception. I have also tried using the MS implementation of this logic as available in this (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwinforms/html/reaworapps1.asp) MS sample. But it appears to suffer from a different issue throwing an exception from within mscore.dll which implies a framework bug. Here is the code used for the Main() method: [STAThread] static void Main(string[] args) { SingleInstanceHandler InstanceHandler = new SingleInstanceHandler(); InstanceHandler.StartUp +=new StartUpEventHandler(InstanceHandler_StartUp); if(InstanceHandler.Run(args)) { // Intialise the tool bar form but never show the form. // The task bar icon will show however. frm_Common_TaskbarIcon frm = new frm_Common_TaskbarIcon(); Application.Run(); } } The code for the SingleInstanceHandler class is attached. I would be grateful for any help anyone can provide on this. I am sure I am just missing something obvious with regard to the life span of the remotable object. But can't seem to see what. Thank you in advance for your help. Regards, Anne. anne.catterick @ no-spam.legendware.co.uk Tag: IE Hosting problem Tag: 88460

    - simple intercommunication (application intercommunication) Hi, I'm after a simple way of sending a message to a previous instance of my small helper application that processes some command line instructions. The app can be configured to remain open (for debugging purposes) & this is where my problem arises. I can find the other (running) instance & close the new instance easily, however, the command line instructions need to be sent to the 1st instance application. I would be most grateful is someone could prove a simple method (even if it means populating a textbox & triggering a buttons 'click' event (on the 1st instance)). Basically, then new app sends a string (the command line) to the existing app (1st running copy) then closes. The running app handles the new command line instructions. Regards - Steve.

    - Localization of Exception messages I have an hard time figuring out how to deal with localization and Exception messages. I have some options: 1) Standardize on english. 2) Pass an "Error Number" to my exceptions, which would ultimately translate to something localized if the app ever wants to display it (by calling the Message property). 3) Use the System.Resources namespace classes each time I throw an exception to make sure the right message is passed to the exception at creation. If I want to localize the throwing of an ArgumentException exception, for example, then only the first method (obviously) and the third method would localize the error message. With the other method, I would have to subclass ArgumentException to my own LocalizedArgumentException that takes an error number (which map to a localized error message) in argument. Anyway, I'm really stuck here, conceptually speaking. I don't know what are the best practices regarding that matter. Etienne Fortin Of the three methods, only the third one, which I don't like (efficiency reason), allows localization of standard .NET Framwork exceptions throwing. Tag: IE Hosting problem Tag: 88441

    - HttpWebRequest not sending cookies Hi All, I'm having problems with HttpWebRequest, HttpWebResponse, and cookies. I copy over the cookies from the server's HTTP response using the following code: if (response.Cookies.Count > 0) { request.CookieContainer.Add(response.Cookies); } And I can see that the cookies are correctly copied since the cookie count on the request now equals the cookie count on the last response.

    - Using dynamic ports (port 0) in TcpListener; how to configure port ranges? Hi. I've created a .net service to transfer files from and to a server from a client. When a file is transferred, the server opens a dynamic port by suppling port 0 to the TcpListener it's created and then communicates this port to the client so that the client knows how to connect (much like passive ftp transfers). Now when a sysadmin uses this service, is there any way he can control which port ranges the .net framework or the underlying service provider (and which provider is that?) uses? Or is there a better way to get a dynamic port number using the .net framework? Tag: IE Hosting problem Tag: 88437

    - IPC between application and windows service Hi! I would like to know what the 'official' method of communication between a windows service (*not* a web service) and an application is. To be more specific: I am writing a windows service with .NET that is used for backuping purposes. The user should for example be able to start a backup manually, that is to send a message to the service to start with the backup now. The service shall not have a GUI, but the application has. Now how to I tell the service to do something from the application? I was able to write a windows service and I am also able to create a windows forms application. My first idea was to use .NET Remoting. But Remoting always uses TCP/IP, right? So that would mean that my application might run into firewall problems, doesn't it?

I have xml that should look like this: <source><g>varname</g> some text <g>varname</g> <g>varname></source> This is a simplified version, but the point is that all spaces in the <source> element are significant. My problem is two-fold. First, the writer is determined to format this like so: <source> <g>varname</g> some text <g>varname</g> <g>varname></source> If I use the xml:space="preserve" attribute, I get the linebreak and indentation spaces. If I don't, I lose the space between </g> and <g>. The problem comes in when there might actually be significant spaces before the first <g> element. Distinguishing between significant spaces and the indentation spaces can't seem to be done. So the solution is probably to have the writer not put the <g> elements on a seperate line. But I can't figure out how to do this. Or maybe there's another way? This is killing me. Please help. Tag: IE Hosting problem Tag: 88410

    - Calling a service from a windows client Hi I'll try and keep this short! When calling a web service async. I can use the Beginxxx method on the generated proxy. But if me 'service' was not a web service but something else, is it better to create a new Thread for the call or use the threadpool; baring in mind that the service call could take a little while (between 1 and 10 seconds, depends on the amount of data returned!) Thanks for your help. Tag: IE Hosting problem Tag: 88409

    - Avoiding deadlock caused by Invoke I?ll try to explain my situation as clearly as possible? J I have a UI form that fires a worker thread. The worker thread regularly updates the UI via an Invoke (naturally). So far so good. The UI form also has a button that can abort the thread. What I?m trying to achieve is for the UI to say that the thread has been aborted once it has indeed been aborted. Here?s my problem: The user hits the Abort button which does an Abort() on the thread (after interrupting a waitsleepjoin) and, as per the MSDN documentation then does a join() to wait for the worker thread to finish (the documentation says that I *must* join). The worker thread captures the abort signal and attempts to update the UI via an Invoke. Of course, the main UI thread is now already joined to the worker thread, so the invoked method called by the worker thread sits in the UI thread queue and is unable to proceed because the UI is waiting for the worker thread to abort. Result à deadlock. I?m sure that there?s a ?standard? way to resolve this presumably common scenario, but I just can?t seem to track it down. Any ideas? TIA Mark Tag: IE Hosting problem Tag: 88392

    - Slow AD query Hi there, I'm creating a little application that between other things will get the logged user information and will do a AD query to get his distinguishedName attribute but that query is taking too long (about 8 seconds). The code for the C# method is as follow: string[] propToLoad = new string[] { "distinguishedName" }; string filter = "(&(objectCategory=user)(sAMAccountName=" + accountName + "))"; DirectorySearcher searcher = new DirectorySearcher( filter, propToLoad ); SearchResult sr = searcher.FindOne(); if ( sr != null ) { return sr.GetDirectoryEntry().Properties[ "distinguishedName" ].Value.ToString(); } return null; where accountName is the logged user account name. Any idea why that's happening? Am I missing some initialization? Thanks in advanced Mr. Fornaris Tag: IE Hosting problem Tag: 88389

Hi

I've created simple windows form application with two windows forms.
On each form IE WebControl is embeded.

I'am loading into IE control page with .Net applet with TextBox and
CheckBox (IE is hosting .Net UserControl)

When the application starts I'm loading Form1. All is working fine. I
can set focus to TextEdit and change state of CheckBox.
When I'm pressing a button on that form, Form2 loads.
When I'm trying to set focus to EditBox I have SecurityException.

When I click continue (not terminate), then select other window (Form2
must lost focus), then set focus to Form2, all works great, no security
warning.

I'm working with default permission sets in .Net.

Why this is working in that way ?

Here is the sample application: http://www.abc.com.pl/download/test_ie.zip

I'm using: WinXP SP2, .Net 1.1 Sp1

Thx 4 Hlp
