    - WorkflowCompiler Error I am using the WorkflowCompiler to compile xoml workflows at runtime into DLL files. This has been working great, but lately after upgrading to .NET 3.5 (it seems - possibly this is unrelated) sporradically I get the following error: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Workflow.ComponentModel.Compiler.WorkflowCompilerInternal.Compile(WorkflowCompilerParameters parameters, String[] allFiles) at System.Workflow.ComponentModel.Compiler.WorkflowCompiler.Compile(WorkflowCompilerParameters parameters, String[] files) at MaryKay.CRM.BusinessLayer.WorkflowUtil.CompileWorkflowXoml(String xoml) in C:\Projects\FrontOffice\SAM-CRM\Current\Service Interface\MaryKay.CRM.Services\WorkflowUtil.cs:line 127 This is inconsistent and nearly impossible to debug (since it appears to happen inside the .NET Framework). We've rebooted the server, done other things and nothing seems to consistently resolve the issue - it just comes and goes. If I don't hear back from anyone on the newsgroups, I'll open an incident with Microsoft. Thanks in advance for your help. Tag: View options Tag: 138097

    - multithreading with WPF I'm trying to understand how to speed up the ui. I have been experimenting with background processing, but am not getting results that I think I should. To experiment, I've created a window that contains a bunch of randomly sized and placed circles. My goal is to be able to resize the window without it hanging or being sluggish. To reduce the processing in the main thread, I've created a BackgroundWorker thread to handle as much processing as I can. Given the design, I believe that the windows sizing shouldn't be affected by the value of numberOfPoints. I expect the update to be delayed, but the resizing to be independent; however, that is not what I am getting. Does anyone have any suggestions? Also, I found that I was not able to freeze a VisualBrush after setting the visual. Any suggestions on that? Here's my sample code: using System; using System.ComponentModel; using System.Windows; using System.Windows.Controls; using System.Windows.Media; using System.Windows.Shapes; namespace FreezeTesting { class FreezeTesting { } class DrawingPanel : Canvas { class WorkData { public Size Size { get; private set; } public WorkData(Size s) { Size = s; } } static Random r = new Random(); const int numberOfPoints = 1000; bool vis = false; BackgroundWorker bgworker = new BackgroundWorker(); public DrawingPanel() { Background = Brushes.White; bgworker.WorkerSupportsCancellation = true; bgworker.WorkerReportsProgress = true; bgworker.DoWork += new DoWorkEventHandler(bgworker_DoWork); bgworker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bgworker_RunWorkerCompleted); } void bgworker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Cancelled == false) { VisualBrush vb = e.Result as VisualBrush; if (vb != null) { Background = vb; } DrawingBrush db = e.Result as DrawingBrush; if (db != null) { Background = db; } } } void bgworker_DoWork(object sender, DoWorkEventArgs e) { e.Result = null; WorkData wd = e.Argument as WorkData; if (wd != null) { if (vis) { DrawingVisual dv = new DrawingVisual(); using (DrawingContext dc = dv.RenderOpen()) { for (int i = 0; i < numberOfPoints; i++) { int rad = r.Next(10) + 10; dc.DrawEllipse(Brushes.Black, null, new Point(r.NextDouble() * wd.Size.Width, r.NextDouble() * wd.Size.Height), rad, rad); if (e.Cancel == true) return; } } VisualBrush vb = new VisualBrush(dv); vb.Freeze(); // throws an error... don't understand why e.Result = vb; } else { GeometryGroup gg = new GeometryGroup(); for (int i = 0; i < numberOfPoints; i++) { int rad = r.Next(10) + 10; gg.Children.Add(new EllipseGeometry(new Point(r.NextDouble() * wd.Size.Width, r.NextDouble() * wd.Size.Height), rad, rad)); if (e.Cancel == true) return; } GeometryDrawing gd = new GeometryDrawing(null, new Pen(Brushes.Black, 1), gg); DrawingBrush db = new DrawingBrush(); db.Drawing = gd; db.Freeze(); e.Result = db; } } } protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo) { base.OnRenderSizeChanged(sizeInfo); if (bgworker.IsBusy) bgworker.CancelAsync(); bgworker.RunWorkerAsync(new WorkData(sizeInfo.NewSize)); } } class Win : Window { public Win() { Content = new DrawingPanel(); } } class App : Application { [STAThread()] static void Main() { new App(); } App() { Run(new Win()); } } } Tag: View options Tag: 138089

    - Problem with SHA256Managed when running multi-threaded Hi, I am experiencing problems with the SHA256Managed class when multiple threads are simultaneously using it. I have reduced the problem to a small piece of code (see below). This creates two threads, each of which repeatedly attempts to hash a string and compare the result to a previous attempt. After a number of tries, the result coming back is different. Running a single thread or locking the hashAlgo object stops the problem. However, this shouldn't be necessary as the documentation states that this class is thread safe when using a static instance. --- Code example: using System; using System.Security.Cryptography; using System.Text; namespace HashTester { class Program { static void Main(string[] args) { for (int i = 0; i < 2; i++) { System.Threading.Thread ff = new System.Threading.Thread(new System.Threading.ParameterizedThreadStart(HashTestFn)); ff.Start("pa$$word"); } } private static void HashTestFn(object o) { HashTest test = new HashTest(o.ToString()); for (int i = 0; i < 10000; i++) { test.Test(); } } } class HashTest { private static HashAlgorithm hashAlgo = new System.Security.Cryptography.SHA256Managed(); private string input; private string output; public HashTest(string toHash) { input = toHash; byte[] hashBytes; hashBytes = hashAlgo.ComputeHash(Encoding.ASCII.GetBytes(input)); output = Convert.ToBase64String(hashBytes).ToUpper(); } public void Test() { byte[] hashBytes = hashAlgo.ComputeHash(Encoding.ASCII.GetBytes(input)); string newOut = Convert.ToBase64String(hashBytes).ToUpper(); if (newOut != output) { throw new Exception("Bad Hash!!!!"); } } } } Tag: View options Tag: 138080

    - How server app can publish multiple Interface as Remoting on separate How Marshal the each Interface on two separate tcp ports channel? this is very often request, we have application that run as service. and we need to control it from within the office on separate port than client connect to get service (for add security). for example: ============ I have server (run as windows services) app that have two kind of service: interface1: for outside users on 50032 port interface1: second on 50033 port only for internal use (for Control Mng on this service) the two Interface (interface1 & interface2) share same Class instance. So I register two channel of tcp (the second one: props("name") = "tcp2" to avoid error: "already exists"), But how I can Attach each Marshal to each Port? some one wrote that need make it on two DomainApp, but how do that with one Class instance?

    - lambda question Hi, I have a question related to lambda expresions and how to prevent exceptions in a FindAll(). The following code create a list of objects and search for an item the "old" way and the "new" way: Create the list. List<object> list2 = new List<object>() { 1, 2, null, 6 }; Search for item "6" the old way. List<object> temp4 = list2.FindAll(delegate(object obj) { if (null != obj) { return object.Equals(obj.ToString(), "6"); } else { return false; } }); Search for item "6" the new way. List<object> temp3 = list2.FindAll(obj => object.Equals(obj.ToString(), "6")); The first method goes just fine because i'm able to check for null items. The second method fails because of the null item. How do i check for null items in the second method ?? Thank you in advance. BR Peter Tag: View options Tag: 138073

    - Read() on ResponseStream of a HttpWebRequest always returns zero Hi, I have to check if a url like http://my_server/abc.aspx?id=123 sends a valid file. The server always returns OK as status code, but sends emtpy files, if the id is not correct. It's not possible for me to change the server side. Content-Lenght is always zero, because files are in a streaming format (I think). I tried to read the first 10 bytes of the file to check if it contains some valid data, but Read(...) returns zero bytes even for the valid ids. If I try the same url in IE, I'm able to download the file. Any hint what I might be doing wrong? Or another way to check the files? regards, Achim Tag: View options Tag: 138063

    - LINQ question This is a multi-part message in MIME format. ------=_NextPart_000_00EE_01C884E8.00DD6E90 Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Content-Transfer-Encoding: 7bit I have a desktop aplication which use an embeded database engine (embeded in the application that is) to store its data. And I used LINQ 2 SQL as an ORMapper to synchronize the database with my object representation in memory. What I want to do is load most object at the start, do in memory work, and occasionaly load additional big data or save the changes. I have a problem with the DataContext.GetTable<T>() mehod. It seems everytime I do a foreach on its retur it will query the database, is that true? So in my particular case I'm better off working with an List<T> which I will initialize from the GetTable<T> result? Just in case I wrote such a list (Code attached) and I wonder if I did it the proper way, if anyone can take a look? Also I have a table like that Data -------- ID int summary nvarchar(256) content image which I loaded in [Table("Data")] class Data { [Column(...)] public int ID {get; set; } [Column(...)] public sring Sumary { get; set; } [Column(...)] public byte[] Content { get; set; } } Now Content is potentially big and I want to use lazy loading, i.e. I DON'T want to load the 'byte[] Content' with the rest of the data (I guess it's easy, just remove the ColumnAttribute), but I DO want to save the Content, if it's not null (i.e. if it has been explicitely loaded/set/modified) when SubmitChanges() is called on the Context. Any tip on how to do that? Moreover, if I only change the content (which will have no ColumnAttribute) how do I mark my entity as dirty in the context?

    - How to capture "printfs" from unmanaged C++ I posted this to the interop group. I'm reposting to troll for a few more ideas. In my managed C# app we capture trace statements and direct them to a log file using trace listeners. Part of the app uses unmanaged C++ dlls, and unfortunately, the C++ printfs don't get picked up and are simply printed to the console window. Is there any way I can capture the output of the printfs and then redirect them to the same file that the trace listener is writing to? I do have access to the unmanaged C++ code if the solution involves not using printfs. The important thing is that the C++ printfs and the C# trace messages end up in the same file. One solution from the interop group was to compile the C++ with /clr and then replace the printfs with Trace.WriteLine(). Any less invasive techniques. Maybe somehow redirecting the printfs to someplace that can be picked up by .Net. Thanks Mitch Tag: View options Tag: 138023

    - System.Timers.Timer and Close/Dispose The short form of this post is as follows. For an instance of System.Timers.Timer, after setting Enabled to False, is there a foolproof way to tell if an Elapsed event will or will not fire? The long form follows. I have a class, MyClass, that declares Private WithEvents MyTimer As System.Timers.Timer Sub New for MyClass initializes MyTimer to fire Elapsed events every second. I have an Elapsed event handler and some public methods. With SyncLock, I've made MyClass instances thread safe. Everything works fine. System.Timers.Timer has Close and Dispose methods, so I when I want to destroy an instance of MyClass, I should Close or Dispose MyTimer. I've coded MyClass.Close to look like this: MyTimer.Enabled = False ' some cleanup I need to do Sleep(100) ' let fire an enroute MyTimer.Elapsed MyTimer.Dispose() ' per IDisposable ' some more cleanup I need to do The reason for the Sleep is because of how Windows/.NET executes MyTimer.Elapsed events. The Timer.Stop documentation says: "The Elapsed event is raised on a ThreadPool thread, so the event-handling method might run on one thread at the same time that a call to the Stop method runs on another thread. This might result in the Elapsed event being raised after the Stop method is called." Stop and Enabled=False do the same thing. The Timer.Stop documentation goes on to give a somewhat elaborate mechanism to overcome contention and race conditions that might arise. My solution is Sleep(100). I don't like my use of Sleep. I don't like the elaborate mechanism in the documentation because it looks like it could fail if someone is messing with thread priorities (note that the mechanism uses Sleep(0)). So, the question is: For an instance of System.Timers.Timer, after setting Enabled to False, is there a foolproof way to tell if an Elapsed event will or will not fire? Tag: View options Tag: 138004

I can do that all fine, however what I'm struggling with is trimming the whitespace from the resultant image. What im doing is creating a blank canvas image (of arbitrarily large size) and doing a translate transform to the centre, then applying a rotate transform, then writing my text. What i want to do is trim all the whitespace from around the edges. Is there some way i can determine the width and height of the text ive written to the image (after the transform) ?

I have both Visual Studio 2005 Pro & Microsoft Office 2007 Pro installed. I'm trying to create my first Office project, but I don't see 'Office' as an available Project Type. I'm following the directions shown here: http://msdn2.microsoft.com/en-us/library/0es5szt7(VS.80).aspx Has anyone seen this before? Any ideas why 'Office' isn't an available project type. Thanks.

    - Metafile & Graphics I have a Metafile and a Graphics attached to it and I do several drawings on the Metafile through the Graphics. After the drawings I need to print the metafile. If I try to print the Metafile right away, nothing shows on the page, now, If I do a Graphics.Dispose() and then print the Metafile, it works without any problem. My problem is that after printing the Metafile I still need to work on it through the Graphics, but if I try to reinitializate the Graphics object with a call of Graphics.FromImage(metafile), I get a "out of memory" error. Is there a different way to create a Graphics from a Metafile ? Is it possible to have access to a Metafile which is attached to a Graphics, without having to dispose the Graphics ? Thanks for any help. ______ Marco Tag: View options Tag: 137973

    - Compiling WF assemblies with /platform:x64 Hello, I have a service application that uses Windows Workflow Foundation as part of its processes. One of the class libraries in this application is a collection of custom WF activities that I have written to represent the bits of business process. The solution compiles fine when compiling with the /platform:anycpu flag and all is good, but when I try to compile the same solution with the /platform:x64 the class library with the WF activities fail with a "error 348: Compilation failed." It goes on to say "Unable to load one or more of the requested types." but that's all the help I get. I'm trying to build the application in a 32 bits machine running Windows XP SP2, but I will run it in a Windows Server 2003 64 bits. On the destination machine I have installed the 64 bit version of the Framework 3.5 and when looking in "C:\WINDOWS\Microsoft.NET\Framework64\v3.0" I can see only two sub-folders: "Windows Communication Foundation" and "WPF", whereas in the 32 bit version of the Framework 3.0 I can see a third folder called "Windows Workflow Foundation". Does it have any relevance? Any help is appreciated. Tag: View options Tag: 137972

    - The installer was interrupted before [AppName] could be installed. I have created a simple Web Application that just contains default.aspx and a web.config. I have added a Web Setup project to this solution, it Built Fine in VS2008. The installer works fine on windows Vista x64, but fails on the Virtual Machines of XP and 2003 R2. The installer reads "The installer was interrupted before [Setup name] could be installed. You need to restart the installer to try again." Both of the installer logs contain this: MSI (c) (AC:48) ... Note: 1: 2262 2: Error 3: -2147287038 DEBUG: Error 2769: Custom Action WEBCA_EvaluateURLsNoFail did not close 2 MSIHANDLEs. The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2769. The arguments are: WEBCA_EvaluateURLsNoFail, 2, Action ended 18:24:08: WEBCA_EvaluateURLsNoFail. Return value 1. I have looked this up and the only offered solution is to run it as administrator. I have tried running it under an Account in Administrators and as the local Administrator and still got the same message. Does anyone know what is going on here? Even if I create a sample project within one of these VM, it still gives me the same error.

    - Need help diagnosing WCF timeout exception Hello, I have a Windows Service-hosted WCF service that occasionally throws an timeout exception, or something that looks like one. The call chain looks like this: Client->WCF Service->COM Server->COM App The exception seems to appear as the call to the service is completing. Interestingly, these exceptions do not seem to affect the tasks the service is performing at the time of the error. If the errors are ignored all subsequent dependent actions are successful. The exception message is: The maximum retry count has been exceeded with no response from the remote endpoint. The reliable session was faulted. This is often an indication that the remote endpoint is no longer available. The inner exception says: The HTTP request to 'http://xpsp2client:8000/CubularityServies/CuIWfcService' has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout. I also occasionally see an exception claiming that I've exceeded the inactivityTimeout of 00:10:00. OK. When I started seeing these I set all the timeout values I could find to 00:20:00 and the behavior was not affected. I'm setting the following timeouts in the .config file: For <binding> : receiveTimeout sendTimeout openTimeout closeTimeout For <reliableSession> : inactivityTimeout For <host> : openTimeout closeTimeout I'm wondering if there are timeout settings that I'm missing. I don't have any values less than 20min yet I get errors telling me I've exceeded timeouts of 1 and 10 minutes. I've used Intellisense to poke around and try to find properties that aren't obvious in the WCF Config Editor, but haven't turned up anything. Any suggestions? Keith P.S. I've turned on verbose logging for the service and am trying to understand them. Some exceptions are shown in the logs but not enough detail is given to pinpoint the source of these faliure.

    - CAS, WPF & plugin question In my application I am able to load plugins, i.e. use reflection look in an assembly for classes implementing a given interface and instantiate them. I would like these plugins to run with restricted right. Like they are not able to access the file system, etc.... How could I do that? Also, from some prelimiary reading it seems I will have to run thess plugin in different AppDomain, but these plugin need to create some WPF.Controls I'm adding to my main form's visual tree hierachy. Is it possible to do that? I mean add in the UITree a WPF.Control which is from a different AppDomain? (I foresee a dispatcher problem) Any tip? (or maybe I don't need to run my plugin in a different AppDomain after all?) Tag: View options Tag: 137956

    - Typed datasets and table table adapters components not showing in Typed datasets and table table adapters components not showing in Toolbox Hi, I have a solution with several projects. One project contains datasets with table adapters. When I opened a usercontrol in design mode, it used to have all datasets and tableadapters in toolbox, under a tab name with the name of the datasets project However, I had to upgrate to a new hdd, and did a clean Windows install, with VS2005, etc Now, when I open te solution and open a usercontrol in designer, I see only the other user controls, but no datasets or table adapters as I used to have before. Sometimes I see a tab with the name of the datasets project, but on it there is a text telling "There are no usable controls in this group" What happend? I mention, on old HDD I had instaled VS2003 and VS2005, on new one I have only VS2005 and installed VS2008 express, but then I removed it (as I thought maybe it caused the issue). I even uninstalled and reinstalled VS 2005, with no luck. Can anyone help me with this? Thank you Tag: View options Tag: 137949

    - Tab and Ctrl+I in a richtextbox Hello, I program a user control which display a RichTextBox and a format ToolStrip. I want to process some shortcut keys. The RichTextBox accepts tab. Ctrl + I is supposed to format the selection in italic. But Ctrl+I is also de code for Tab. So when I press Ctrl+I, a tab is inserted (replacing the current selection) AND the new selection is formatted in italic. How can I do this ? Do I have to inherit first the standard RichTextBox and override the OnKeyDown method ? -- Fred foleide@free.fr Tag: View options Tag: 137942

    - Syntax Difference C#/VB.NET when calling a Method Hi. I'm a VB.NET developer learning C#, and I have a simple syntax question. In C# whenever you invoke a method you need to include the parentheses () after the method name even if there are no parameters. In VB.NET you don't have to do this. For example - IDataReader oReader; while (oReader.Read) //This will throw an exception while (oReader.Read()) //This is the correct way. I'm just curious why C# requires this but VB.NET does not.

I would appreciate some help. In a certain forlder I have, Windows XP keeps

or preference to set. Windows XP help was no help. Thanks
