    - Using a Broadcast message on an intranet Hi: I need a way to make sure that only one instance of a program is running on a particular intranet. I thought that some kind of Broadcast message might do the trick, or maybe a UDP query. I'm using a WinForms application on .NET 2.0 Can anyone help me with this? TIA, Martin.

    - Updates to .NET Framework 3.0 Hi I have installed the 3.0 version on all clients in the network managed by WSUS. On just one client the - KB932394 - KB932471 patches just don't install. They are offered over and over again and always quit installing with error. I have tried to reinstall NET Framework 3.0 but it did not help. Someone an idea?

    - ReplacerStream Hi, I need to use a stream that I can configur to replace some input string with another. It is probably not very difficult to do but I can't imagine that this has not been written dozens of times before. However I can't find something like it on the internet. Does anyone know of such an example or has code? Or should I be creating an impelementation of TextWriter/Reader in stead of of Stream?

    - XAML, dynamically created RadioButton, and WordWrap? I have an app that presents a variable number of radio buttons (with variable text) that are created dynamically on a HeaderedItemsControl. As far as I can tell, the RadioButton doesn't supports (word or otherwise) wrapping, but will present multiple lines of text, so I could implement word wrapping by inserting NewLine(s) if I could just determine how wide my text is... It is occasionally too wide for a single line, and could theoretically be several lines. I would *really* like to do this when I create the controls and assign the texts and handlers (this is after the window has been shown), but while I can get the initial DesiredSize AND the first iteration after that, it seems I can't get there from here: It won't tell me the size until the layout is final - but the layout won't be final until I know the size of my display text. What can I do (.Net 2.0 w/FW 3.0, VB preferred, but except for some differences in threading and delegates, I can deal with C#)?

    - Accessing UNC file share with credentials? From a .NET 1.1 app: need to access a file share on a remote server by its UNC path, i.e., \\server\folder\subfolder\, using specific username and password. The problem is that the credentials are local to the remote server. Therefore, impersonating that user when accessing the share is not possible. One solution is to map a network drive using the credentials, but it seems kind of ugly and old school. Is there any other way? Thanks!

    - SMTP Email Not Working from Application_Error handler in ASP.NET 2 I have an ASP.NET 2.0 Web Application. I am trying to send an email to myself from Global.asax in the Application_Error event handler. I have been able to successfully send emails from the rest of the application using the exact same logic. For some reason, it does not work in global.asax. I get a "Failure Sending Mail" error message with a more detailed explanation of "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.". This is in a hosted environment, and it IS working for other pages in the app (making me think I need to do something different in the Application_Error function). I get this problem any time an error is thrown within the application and the Application_Error event handler is called. I have a site in production, and to test the error handling in production, I have created a button with an event handler that when clicked will throw an exception. I have tested it by adding "throw new ApplicationException("This is a test exception being thrown...");" and by throwing a named exception "throw new DivideByZeroException();". It seems as if in the Application_Error function the network connection is in an unstable condition. I am using the System.Net.Mail class. Below is my code and the detailed error (notice I have some general information stored in web.config which is pasted below as well): GLOBAL.ASAX -------------------------------------------------------- void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs Exception ex = Server.GetLastError(); string strEmailAddressTo = "myemail@test.com"; string strEmailAddressFrom = "myemail@test.com"; string ErrorMessage = ex.Message + "\nSOURCE: " + ex.Source + "\nFORM: " + Request.Form.ToString() + "\nQUERYSTRING: " + Request.QueryString.ToString() + "\nTARGETSITE: " + ex.TargetSite + "\nSTACKTRACE: " + ex.StackTrace; //1) Create the mail message instance MailMessage mm = new MailMessage(strEmailAddressFrom, strEmailAddressTo); //2) Assign the Mail Message's Properties // Subject mm.Subject = "ERROR OCCURRED"; //3) Body mm.Body = ErrorMessage.ToString(); mm.IsBodyHtml = false; //4) Create the SMTP Client Object SmtpClient smtp = new SmtpClient(); //5) Send the mail message (will use the web.config settings) smtp.Send(mm); } web.config ------------------------------------------------------------ <system.net> <mailSettings> <smtp> <network host="[mynetworkHost]" port="25" /> </smtp> </mailSettings> </system.net> DETAILED ERROR MESSAGE: ------------------------------------------------------------- <ExceptionInformation><AdditionalInformationProperty ExceptionManager.MachineName="XXXXX" ExceptionManager.TimeStamp="10/2/2007 1:32:25 AM" ExceptionManager.FullName="Microsoft.ApplicationBlocks.ExceptionManagement, Version=1.0.2830.35366, Culture=neutral, PublicKeyToken=null" ExceptionManager.AppDomainName="/LM/w3svc/814863/root-11-128357766911129800" ExceptionManager.ThreadIdentity="" ExceptionManager.WindowsIdentity="NT AUTHORITY\NETWORK SERVICE" /><Exception ExceptionType="System.Net.Mail.SmtpException" StatusCode="GeneralFailure" Message="Failure sending mail."

    - Registering a COM Dll with an MSI I'm creating an installer for a project that I've created. My project is a Managed C++ 2005 project, and it compiles out to a COM Dll. I need to register this COM Dll in order for the final product to function properly. Initially I tried registering the Project Output, but I understand that there are issues with doing that, so I have excluded the Primary Output for my project, and I have added the dll from my Release folder directly. In the properties for my Dll I have set the Register property to vsdraCOMReleativePath, but I have also tried vsdraCOM, in both cases the dll does not register on the target machine. If I run regsvr32 on the target machine my dll will register and the application will work. Does anyone have any suggestions on how to get this work correctly. I appreciate any help. I should also probably point out that I did not remove the Primary Output, because I like how the MSI project will automatically determine the dependencies if the Primary Output is with the MSI. I only excluded the Primary Output. Tag: If you want do delete your site from our spam bases - Tag: 134101

    - Differing XML Schemas? If I use the Dataset.WriteXml for my datasets from a windows application running under the framework v1.1 the schema written to the text files sometimes differs from that of the same dataset written from a WebService. Both projects use the same library to generate the dataset and write it to file. When the windows application writes the file it contains msdata:locale=enGB but this tags is missing when the file is generated by the WebService. Also this behaviour only happens at some sites where our software is installed. My development PC doesn't experience this problem. Any ideas?

    - Collections od KEYS only : BOOLEAN VS OBJECT, False Vs Null/Nothing In a previous question I asked if there were collections similar to SortedList or Dictionary which would hold KEYS only, No values. It seems that the framework does not have such "reduced" collections, but one can use the standard one, adding as value a Null/Nothing value or a boolean (of creating a collection by inheritance). I am wondering what is most advisable to use as type for the values: Boolean or Object ? For instance: C# SortedList<MyKey, bool> MyListB = new SortedList<MyKey, bool>(); MyListB.add(new MyKey(), false); or SortedList<MyKey, object> MyListO = new SortedList<MyKey, object>(); MyListO.add(new MyKey(), null); VB dim MyListB as new SortedList(of MyKey, Boolean) MyListB.add(New MyKey, false) or dim MyListO as new SortedList(of MyKey, Object) MyListO.add(New MyKey, Nothing) I am wondering if using a value type (boolean) instead of a reference type would be more inefficient ? Your opinion ? -P Tag: If you want do delete your site from our spam bases - Tag: 134048

I'm going to start a new project from scratch in 2.0, however, so am looking forward to that. I'd like to know how hard would it be to built the solution locally using the built-in SQL Express, and then migrated that to the product server? Is it a rather simply process? Complex? Any specific guides/tutorials on how to do it? Ideally I'd be going to from Express to MS SQL, but what if I went to MySQL? Still viable?

    - Global CBT Hooking Hello, I'm developing an application which relies heavily on global hooks and apparently C# does not support this type of hooking. What I have in mind is to make a dll (in Delphi) that handle all the hooking and call a user defined c# function for further handling, is this possible, could I link the dll function with the C# function without any complication? I considered moving the whole project to Delphi, the Visual Sudio IDE was the only thing keeping me from doing so. Should I use C# for this type of project or should I consider other alternatives, as hooking in Delphi is straightforward.

    - HELP - Why are Worker thread's child thread's entering WaitSleepJoin? Plus Context Deadlock.... Using VS2005, VB.NET, I have a worker thread (started by main UI thread) that in turn spawns and monitors child threads to execute several long running process. The problem is that the worker thread's children are entering WaitSleepJoin and thus my worker thread just hangs doing nothing and just loops. My question is why are my child thread's entering waitsleepjoin state? There is no sleep or spinwait being called in the child's thred process. Also, I am getting the dreaded content deadlock and con't figure out why: The CLR has been unable to transition from COM context 0x1d1ba0 to COM context 0x1d1e80 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations. The deadlock even happens if the code in StartUpload (worker thread's process - see full lisiting below) executes to the end (which I thought would cause the worked thread to Stop). How can I determine where the deadlock is? BTW, I've tried diabling MDA's LoadLock exception and adding a ...mda.config file to no avail (I don't think that VS is starting the debugger starting the MDA erronously). Beow are some code excerpts that show (1) the start of the worker thread; (2) code in the work thread's proc that spawns and monitors child threads and (3) the child thread proc. Let me know if you see any problems. One thing I'm not sure about - that's is the number of event's that I am raising. These events are handled in my main UI thread so the user can get status updates. The event handlers are invoking delegate functions (so they run on the main UI thread) using BeginInvoke in attempts to avoid blocking on the RaiseEvent calls in the worker thread. Selected code excerpts follow: ---------------------------------------------------------------------------= =AD------------------------------- Private Sub btnUpload_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpload.Click Try Dim xRoot As XmlElement =3D xDataDocument.DocumentElement 'xDataDocument is an XML having info about audio files...

    - Asynchronous calls to a web service - 100,000 a minute Hi, I've got a requirement to poll a web service for data but it needs to be done very frequently. The web service call is straight forward, it just returns a simple table of data with no more than 50 rows. It's a third party web service so i have no control over it. The problem is each call is on a per user basis and the client said if its succesful it there could be 100,000 users. The frequency of each call could be once a minute so that could be 100,000 calls a minute. I'm designing the client app to make the requests and i'm thinking each request should be asynchronous but i'm not sure this is enough. I've got no experience of multi-threaded development so i'm not sure if this would help (making the requests over many threads). Also I'm concerned about bottlenecks. If the app I built was capable of making 100000 requests a minute (possibly at the same time if its multi-threaded) then would the network handle this load and also could the web service handle this many requests at once (i know the W3C recommends only 2 client connections at once so that could be an issue). Anyway, any help or thoughts would be much apprecieated. Thanks, Alex Tag: If you want do delete your site from our spam bases - Tag: 134010

    - VC++ deprecated function warnings I'm consuming a third party library that allows me to intregate our system into theirs. They wrote their library in Visual Studio .NET, and they make liberal use of unsafe C functions. I'm consuming their library in Visual Studio 2005, and as a result I keep getting 'xxxx' was declaed deprecated warnings, where xxx is the name of the function. I know there is a way to turn this off but I haven't been able to get it to work. I tried adding _CRT_SECURE_NO_DEPRECATE to my Preprocessor Definitions, but the warnings keep coming up. This makes it impossible for me to detect the usefull warnings, and I'm not feeling up to re-writing their library. Any help would be appreciated.

    - Best way to design multithreading application Ok, I appreciate any help you can give me. I am somewhat new to threading, only understanding it conceptually, and I use the Threading namespace for the sleep() command. So, any suggestions with code would also be beneficial. Basically, I need help designing how my threads should interact. Currently, the application acquires a bit of data, processes it, writes it to a file, sounds alarms if necessary, adds it to the UI (charts and tables), and then loops to acquire more. This results in data acquisition times of several seconds, and we need it under a second. The data acquisition is more important than UI updates, but not at the expense of UI updates never taking place. Based on the information I know, here is what I would do (but don't know how): Thread A, which is high priority, sits there and acquires data over and over, adding it to a Queue 1 as it acquires more. Thread B, which is medium-to-high priority, loops over and over, and when it sees data in Queue 1, it writes it to a file and sets any alarm states. It then puts the data in Queue 2. Thread C, which is lower priority, loops over and over, and uses any data in Queue 2 to update the UI. Is that the correct way to design a good solution for this? If so, I am worried about a few things: 1) If data collection is high priority, and the other threads cannot get enough CPU time, will either Queue fill up too quickly, effectively stalling the application (i.e. how would I "slow down" the acquisition thread if I notice the queues filling up)? 2) Because of these extra queues filling up, am I actually taking more time to process each acquisition given the memory needs of such a system (i.e. should I keep it a single-threaded model)? 3) Is there even a way to prioritize threads in such a way that Thread A is always exactly (or rather, close to) 1 second per acquisition run, and then Threads B and C use up the extra time, with B being most important? 4) What happens when Thread A enqueues a new chunk of data at the same time Thread B is dequeuing one? Same for B and C. Is this where the "lock" keyword comes into play? Thanks in advance, and I hope someone here can shed some light on how to accomplish this...

    - Find Name of Function How can I find the name of the current function being executed. For example, lets say I have the following function void Blah(int? y){ int z; try { z = y; } catch(Exception ex){ throw ex } } Which will throw an exception if y is null(Nullable). I am writing a class to log any exceptions to a SQL database, a column indicating the name of the current function where the exception was generated would be very handy. So instead of throwing the exception, I would log it, and handle the exception gracefully. Not to sure if this can be done, on binaries not compiled without debugging symbols.

    - Backwards compatibility of System.Configuration.Configuration? Hi... I've got an old app config that I'm trying to work with using the new 2.0 config framework, e.g. <configuration> <configSections> <section name="Test" type="System.Configuration.NameValueFileSectionHandler"/> </configSections> <Test> <add key="test" value="this"/> </Test> </configuration> If I parse this config with ConfigurationManager.OpenMappedExeConfiguration() or OpenExeConfiguration() and then execute config.GetSection("Test"); I get back a System.Configuration.DefaultSection. My problem is that I can't seem to do much with that. SectionInformation.Type = "System.Configuration.NameValueSectionHandler", but SectionInformation.ConfigSource = "" and ElementInformation.IsCollection = false ElementInformation.Source = null I found some articles/examples of how to code new section handlers to the ConfigurationSection/ConfigurationElement model, but is there any way to get backwards compatibility to old handlers?

    - System unauthorizedaccess twice a day! Hi, I have made some software in C# that communicates with a virtual COM port (USB->RS232 converter) and the parallel port using the inpout32.dll (http://logix4u.net/Legacy_Ports/Parallel_Port/ Inpout32.dll_for_Windows_98/2000/NT/XP.html). Furthermore it writes information to files on the hard drive once in a while (log file and an id that is saved to a file about every 5 seconds. When I tested it I did not find any problems but now when it is used in a production environment they get an unauthorizedAccessException about twice a day: http://www.therkelsen.info/temp/error.jpg As I understand the error it has either something to do with accessing a file, the virtual COM port or the parallel port. My best guess is that the USB->RS232 converter is a little unstable. What are your experiences with this type of error? I will provide more details when I know more but for now I don't have access to the PC in the production environment and am not able to make the same setup at home.

    - WCF Solution Problem: An External resource which I have no control over delivers data via TCP/IP. In addition, there are files delivered to specific folder locations on the network. There is a very poorly written system ("server") that uses Sockets to intercept the data that comes in via TCP/IP and I/O to pick up the files that are delivered. The system that delivers the data via TCP/IP knows what IP address and port to connect to in order to push the data down to the existing "server" that is running. This "server" must be replaced by a more stable and better system. Ultimately what must happen is the data must be intercepted and delivered to other processes (whatever processes that wish to subscribe to receiving the data). How could this be accomplished using WCF? To intercept the TCP/IP stream as well as the physical files and publish them to subscribing processes? -- -Demetri Tag: If you want do delete your site from our spam bases - Tag: 133947

    - SmtpClient.send error I have a web page that sends emails to a mailing list of 700+ recipients. It ran to about 435 and quit, and was unable to make a connection to send again. I do not yet have verification that the 400+ emails actually arrived. I *think* but do not know for sure that my smtp server is exchange. It is hosted with an isp (webhost4life). 1) It was recently posted that smtpclient caches the connection. Not sure if this is related. Thoughts? 2) Could I be overflowing the server in some way? Any ideas on how to avoid this, even at a conceptual level for another approach to sending? 3) If I dispose of and re-create the message object, could that possibly help? 4) If I put in some form of delay to not blast the emails in to the server so fast, could this help me get more messages through? Kinda hard to test this and test the theories when I need to send 400+ emails for each test before the error strikes!

First, I'm wondering if I'm just missing something here (is the msdn page wrong)? Second, I'm wondering why System.Configuration.Configuration.AppSettings was implemented differently than System.Configuration.ConfigurationManager.AppSettings (which is a NameValueCollection)?
