    - mscorlib.dll problem? We are using sqlite3 for local data storage for our applications. 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?

    - Dynamically loading controls -> loosing type Hi NG We want to load controls dynamically and create them on a WinForm. Doing so, we seem to loose type information. 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. Any hints? Thanks for all the help we get Cheers Peter Tag: Stepping through application while debugging is incredibly slow Tag: 88482

    - 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: Stepping through application while debugging is incredibly slow 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.

    - 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: Stepping through application while debugging is incredibly slow Tag: 88460

    - run windows forms from localIntranet_zone Hello! I have a windows forms application developed in VS.NET 2003 (C#) that I want to install on the intranet. I've created a strong_name.snk file, compiled it with the app, installed it on the server and on the client machine, I added the child code group under LocalIntranet_Zone, for that assembly, with full trust. I did it on two separate intranet systems and it worked in one place but not the other. I've created a simple test-application (also with strong name) and just copied the file to the network share but it gave me a warning that the application was running in a partailly trusted context. Is it some security settings in Windows causing this error? Where should I look? Thanks! /Miro Tag: Stepping through application while debugging is incredibly slow Tag: 88458

    - 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. (PS, if this is the wrong NG, let me which one is the right NG & I'll repost there!) Tag: Stepping through application while debugging is incredibly slow Tag: 88455

    - 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.

    - 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. But, when I come to enumerate the headers of the request, the cookies are not listed, nor do they show-up in the HTTP headers gleaned using a packet sniffer (Ethereal). Can anyone suggest factors I should be exploring, I've been going round and round this problem for days :-( Thanks, Tim.

    - 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: Stepping through application while debugging is incredibly slow Tag: 88437

    - Installing a windows service 'manually' Hi! I created a windows service and was able to install and deinstall it with the 'installutil.exe' utility. Is there any possibility to install it directly from my application? The documentation only says that it *should* not be done but neither why it shouldn't be done nor how it is possible. I created a setup application to install it and that works. But I would like to spare my users to either run another setup or work with the installutil-program. Two buttons 'install service' and 'uninstall service' would be much better. Please tell me how to do that or why I shouldn't do so.

    - 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?

    - System.Xml - Controlling linebreak/indentation on child/inline ele I'm going insane fighting against the xml reader/writer. 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: Stepping through application while debugging is incredibly slow Tag: 88410

    - 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?

Now on a hunch we RE-compiled the VFP message.dll using VFP 7.0 and re-added it to the Dotnet solution, after recompiling as outlined in the steps 1 and 2; and Viola there was no problem and all worked fine What is this weird behaviour about, please enlighten us !!!!

    - Visual Studio Functionality We're having a bit of a quandary at my office and this seems to be the perfect place to get the answer and perhaps some clarification. Currently, the "official" architecture for my organization is J2EE. It is my understanding that the .NET framework serves essentially the same purpose and that it exists as part of the operating system in Windows. In the past there have been a number of applications developed in either MS Access or Visual Basic. Many of these may never be converted to Java and it certainly won't happen anytime soon. As a result, some people are asking for newer versions of Visual Basic (i.e. .NET) in order to maintain and improve these existing applications. Is it possible to use Visual Studio and only develop "straight" VB code that does not use the framework (this has been specifically prohibited by upper management)? Do all versions of Visual Studio give you access to the framework or only the enterprise versions? If all versions give you access is it possible to determine if/when you are using the framework? I would really appreciate some guidance from those of you who are very familiar with this product. Thanks in advance. Tag: Stepping through application while debugging is incredibly slow Tag: 88354

    - System.Web.Mail Transport Error This question falls into the category..."nothin a reboot won't fix"... The exception I receive is as follows: "The message could not be sent to the SMTP server. The transport error code was 0x800ccc14. The server response was not available." If I want the exception to stop occurring (for a while), I just reboot the machine that the app and SMTP Service is running on. Note that SMTP Service start and stop does not help. Please note that I never know how long the app will run until the error occurs sometimes 1 hour, sometimes 8 hours. The transport error code was 0x800ccc14 is a winsock error, "SOCKET_INIT_ERROR Unable to initialize Winsock". Any ideas? Thanks!

    - Code generation for array of components Hello all, I am trying to create a custom component which contains an array of another custom component. A property is added to wrap the array - this allows .NET's built-in property editor to provide a comfortable means to populate and edit the array. The problem I have run into is that after all this is done, the array itself is never generated into code and all the created objects simply spill onto the form as well - which can be a problem because of the size of the array I would like to create. I would prefer not writing a custom editor and code generator because I think .NET should have all I need, I just need to figure out how to control it. Hopefully this example might clarify what I am trying to do. Assume I create a new component, and add the following code to it: ************************** private System.Timers.Timer[] tarray=null; public System.Timers.Timer[] TArray { get { return tarray; } set { tarray=value; } } *********************** Now, after I compile the class and add it to the toolbar and drop an instance of the component onto my main form, it has a TArray property. I can click on this property's ellipsis button ("...") and populate this property with timer objects. As I do this, 2 problems occur: 1 - when I'm done and click OK, the array is never created in code - it remains null regardless of any editing that occurs - so the next time I edit my object's TArray it is empty again 2 - the timer objects are created, but apart from the array and they appear separately in the form editor In this example, I would still like to be able to create timer objects outside the TArray property and have them appear on the form - only timer objects which are created inside the array should not appear separately. Any tips on how to generate the desired behavior (array's code generation and only the container object in form editor) are greatly appreciated! Thank you, Markus Tag: Stepping through application while debugging is incredibly slow Tag: 88346

    - problem moving console appliation to send email to server I created a console application using .net to email information out on a monthly basis. My problem is this. It works from my pc and anyone else with the visual studio .net, but not from the web server. Was i supposed to do anything else other than build my solution and copy my exe to that server. When they double click on the exe they get the following error message. What else should be down there other than the framework.

    - ASP.NET 2.0 View State Error/Problems - HELP!

    - Monitor class not working as specified Hi! I have trouble with the Monitor class. I did some troubleshooting and finally figured out the problem. The thing is, the Monitor class simple does not work as specified. Better said, if used by the framework through lock( obj ) statements it works fine, however if used through Monitor.Enter( obj ) and Monitor.Exit( obj), deadlocks can occur. Here is a simple example that shows this behavior. If the example is run as specified everything is fine. If the lock statements are commented, and Enter & Exit statements uncommented deadlock occurs. Why this happens? .NET framework help specifies that this should be the same. I found in the help, that Monitor maintains Waiting and Ready queues of threads for each object, but I haven't found the clear explanation of the meanings of this queues. Any sugestions? using System; using System.Threading; namespace ConsoleApplication4 { /// <summary> /// Summary description for Class1. /// </summary> class Class1 { string s; /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main(string[] args) { Class1 c1 = new Class1(); Thread t1 = new Thread( new ThreadStart( c1.f1 )); Thread t2 = new Thread( new ThreadStart( c1.f2 )); t1.Start(); t2.Start(); t1.Join(); t2.Join(); Console.ReadLine(); } public Class1() { s = "0"; } void f1() { lock( s ) { //Monitor.Enter( s ); broj = (Convert.ToInt32( s ) + 1).ToString(); Console.WriteLine( s ); //Monitor.Exit( s ); } } void f2() { lock( s ) { //Monitor.Enter( s ); broj = (Convert.ToInt32( s ) + 1).ToString(); Console.WriteLine( s ); //Monitor.Exit( s ); } } } } Tag: Stepping through application while debugging is incredibly slow Tag: 88338

I have a ASP.NET application that I'm trying to step through. Each line
of code takes about 3 seconds to execute as I step over it while
debugging. It doesn't matter if it's a method call or a simple variable
declaration, it's incredibly slow.

My watch window is empty.
The variables in my locals window are all collapsed.

This problem just started. There were no major changes to the
application when this occurred.

Any ideas?

Thanks,

alex

I created a blank solution and added the web app to it and the debugger
is back to normal speed. Guess something got corrupted in the solution
file?
