    - About drawing something on a Control. i have added a Panel with size = (100, 100). Then i would like to draw a Line on that Panel. So i write: I write some codes on the OnPaint event of the Panel: private void panel_Paint(...) { Graphics g = e.Graphics; g.DrawLine(new Pen(Colors.Red, 6), new Point(0, 0), new Point(100, 100)); } Then it can draw a line on the Panel, but when part of the Panel is covered by other windows, the hope Panel will call OnPaint, and the whole line will be redraw, is there any way to prevent it??Thanks Tag: Can Windows services be extended using .NET add-in model (System.AddIn)?

    - Strange .NET Runtime 2.0 error thrown in a WPF application Has anyone seen a similar exception? This is a WPF application installed via ClickOnce and we have one user who gets it consistently on startup. We've also seen it occasionally while the applicaiton is running. We've instrumented the application with exception handling in most methods we have control over, but due to the nature of a WPF application startup wiring (or our lack of knowledge), we haven't been able to implement a 'catch all' handler, so we have no idea where this is coming from.

    - FYI: .NET Source Code to Become Available Hello, for your information in case you didn't yet notice the news: Microsoft has announced plans to give developers the ability to view .NET class library source code. This is announced here: http://weblogs.asp.net/scottgu/archive/2007/10/03/releasing-the-source-code-for-the-net-framework-libraries.aspx Says the blog: ---------------- "...the ability for .NET developers to download and browse the source code of the .NET Framework libraries, and to easily enable debugging support in them. [...] We'll begin by offering the source code (with source file comments included) for the .NET Base Class Libraries (System, System.IO, System.Collections, System.Configuration, System.Threading, System.Net, System.Security, System.Runtime, System.Text, etc), ASP.NET (System.Web), Windows Forms (System.Windows.Forms), ADO.NET (System.Data), XML (System.Xml), and WPF (System.Windows). [...] The source code will be released under the Microsoft Reference License (MS-RL). You'll be able to download the .NET Framework source libraries via a standalone install (allowing you to use any text editor to browse it locally). We will also provide integrated debugging support of it within VS 2008." ---------------- Sounds great to me!

    - Toolstrip and MDI application I am trying to get write an MDI application running using the ToolStrip control(s). I have the application running with types of two form. Each form represents a type of document. Each has its own custom menus and toolbars. The MDI application runs up and I create new documents of each type. When a form is activated, dot net merges the menus and the app I merge in the toolbars using RevertMerge and Merge. One of my forms has about 6 toolbars, the other has 2. When I switch between the two document type, the toolbars change position; I activate form1, move the toolbars using the mouse, activate form2, then switch back to form1- the toolbars have moved. I am also having problems saving and restoring the positions of the toolbars using ToolStripManager.LoadSettings and ToolStripManager.SaveSettings. This showing the same behaviour (although it may be caused simply by switching between the windows). Has anyone successfully implemented an MDI app using these controls? I have a test app if anyone would like to see it - where the best place to post it? Paul Wardle Tag: Can Windows services be extended using .NET add-in model (System.AddIn)? Tag: 134152

    - How to call C# callbacks from C++/CLI? Hi, Tried searching Google on this topic but not many came up. Basically I have a C# GUI client that wants to receive 'notifications' from a worker DLL (which is implemented in C++/CLI). So far, from C# I am able to call any method directly in C++/CLI DLL. But I would like to have the C++/CLI invoke some callback methods from within C# (some event notifications so that the GUI updates its UI). In the old days using C/C++, I could do this easily by passing a class object ptr to the DLL and have it invoke callback methods declared in that class. Can I do the same thing in .NET? Since there is no header file, I don't know how to 'tell' the C++/CLI component which C# callback methods to use. Thanks. Tag: Can Windows services be extended using .NET add-in model (System.AddIn)?

    - 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: Can Windows services be extended using .NET add-in model (System.AddIn)? 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?

On an x64 box I need to force this to run in x86 mode under WOW64 *without* recompiling the application . (i.e. as if the code had been compiled targeting x86.) Is this possible - if so, how?

    - 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: Can Windows services be extended using .NET add-in model (System.AddIn)? Tag: 134048

    - problem with System.OutOfMemoryException In my code I am manipulating/creating/destroying in memory representation of big XML file (as in a few MB of CDATA in them (embeded bitmaps)). At some stage (and I am in no way under any memory stress as my application is using only about 500MB of memory and I have 1GB free, without counting the virtual memory) I have this out of memory exception happening, in code snippet looking like that: ===== public static void WriteXml(System.Xml.XmlWriter writer, IEnumerable<string> resources, IResourceProvider provider) { writer.WriteStartElement("Resources"); writer.WriteElementString("ResourceProvider", provider.ID.ToString()); List<string> resourcesWritten = new List<string>(); foreach (string resource in resources) { if (resourcesWritten.Contains(resource)) continue; writer.WriteStartElement("Resource"); byte[] data = provider.LoadData(resource); writer.WriteElementString("ResourceName", resource); string b64Data = Convert.ToBase64String(data); // ========== OutOfMemoryException below writer.WriteElementString("base64Data", b64Data); writer.WriteEndElement(); resourcesWritten.Add(resource); } writer.WriteEndElement(); } ===== the error stack is: ==== System.Xml.dll!System.Xml.XmlWellFormedWriter.WriteString(string text) + 0x55 bytes System.Xml.dll!System.Xml.XmlWriter.WriteElementString(string localName, string ns, string value) + 0x29 bytes System.Xml.dll!System.Xml.XmlWriter.WriteElementString(string localName, string value) + 0xb bytes > NovaMind.Data3.dll!NovaMind.Data.ResourcesHelper.WriteXml(System.Xml.XmlWriter > writer = {System.Xml.XmlWellFormedWriter}, > System.Collections.Generic.IEnumerable<string> resources = > {NovaMind.Data.NMMapBranch.get_ResourcesInUse}, > NovaMind.Data.IResourceProvider provider = > {NovaMind.Data.NMDocumentPackage}) Line 27 + 0x13 bytes C# ==== When I look at the internal of the various object involved with the debugger I could see that: data.Length ~= 7 Mb (~ 7 e+6) and "Writer" is wrapper around a StringBuilder which MaxCapacity is around 2 GB (2e+9) and which current Length is "only" about 25 Mb (25e+6).

    - Migrated SQL Express to a viable DB. Easy? Hard? I haven't been able to play in ASP.net 2.0 as much as I'd have liked to this past year. 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? Of coruse, if I was using MySQL, I suppose I could just install that locally. -Darrel Tag: Can Windows services be extended using .NET add-in model (System.AddIn)? Tag: 134034

    - 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.

    - 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: Can Windows services be extended using .NET add-in model (System.AddIn)? Tag: 134010

    - 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...
