    - Multiple versions of framework at the same time What happens if I write a .net program using the framework 3.5 and I use a 2.0 dll? Are both frameworks (3.5 and 2.0) loaded at the same time "eating" more memory, or does the 2.0 dll uses the 3.5 framework? --- thanks Tag: what's the difference between WebService & WCF Service?

    - 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: what's the difference between WebService & WCF Service?

    - 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: what's the difference between WebService & WCF Service?

    - 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: what's the difference between WebService & WCF Service? 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? (i.e. I would need an 'UpdateOnSubmit()' method in the table, but it doesn't exists..) ------=_NextPart_000_00EE_01C884E8.00DD6E90 Content-Type: text/plain; format=flowed; name="LinqList.cs"; reply-type=original Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="LinqList.cs" =EF=BB=BFusing System; using System.Collections.Generic; using System.Data.Linq; using System.Linq; using System.Linq.Expressions; using System.Text; namespace Galador.Utils.SQL { /// <summary> /// This will hol an in memory representation of some LINQ data. /// All data will be loaded at creation time and furter work would /// be done in memory. /// </summary> /// <typeparam name=3D"T"></typeparam> public class LinqList<T> : IList<T> where T : class { List<T> data; public LinqList(DataContext ctxt) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>()); } public LinqList(DataContext ctxt, Expression<Func<T, bool>> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Expression<Func<T, int, bool>> = predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Func<T, bool> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Func<T, int, bool> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public DataContext Context { get; private set; } #region IList<T> Members public int IndexOf(T item) { return data.IndexOf(item); } public void Insert(int index, T item) { if (item !=3D null) Context.GetTable<T>().InsertOnSubmit(item); data.Insert(index, item); } public void RemoveAt(int index) { T item =3D data[index]; if (item !=3D null) Context.GetTable<T>().DeleteOnSubmit(item); data.RemoveAt(index); ; } public T this[int index] { get { return data[index]; } set { RemoveAt(index); Insert(index, value); } } #endregion #region ICollection<T> Members public void Add(T item) { Insert(Count, item); } public void Clear() { Context.GetTable<T>().DeleteAllOnSubmit<T>(data); data.Clear(); } public bool Contains(T item) { return data.Contains(item); } public void CopyTo(T[] array, int arrayIndex) { data.CopyTo(array, arrayIndex); } public int Count { get { return data.Count; } } public bool IsReadOnly { get { return false; } } public bool Remove(T item) { int index =3D IndexOf(item); if (index < 0) return false; RemoveAt(index); return true; } #endregion #region IEnumerable<T> Members public IEnumerator<T> GetEnumerator() { return data.GetEnumerator(); } #endregion #region IEnumerable Members System.Collections.IEnumerator = System.Collections.IEnumerable.GetEnumerator() { return GetEnumerator(); = } #endregion } } ------=_NextPart_000_00EE_01C884E8.00DD6E90-- Tag: what's the difference between WebService & WCF Service?

    - 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: what's the difference between WebService & WCF Service? 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?

    - EnterpriseLibrary.Logging Hi all, I have installed EnterpriseLibrary v3.1 (latest version) on my pc. When I create the app.config file using the "EnterpriseLibrary Configuration" utility, I get an error saying it can't detect the EL.Logging.dll file. I fixed the problem by setting the PublicKeyToken= "null" instead of its default PublicKeyToken="b03f5f7f11d50a3a". eg. configSections> <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" /> <section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" /> </configSections> The thing is that I can't understnad why this error is occuring in the first place. This pc is newly set-up and it has never had any prior versions of EL installed on it. The "EnterpriseLibrary Configuration" utility comes with this v3.1 setup.

    - GDI and Rotating Text Hi, I want to use GDI to rotate some text at an angle and output the resultant image to the asp.net response stream. 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 know i can manually get the text dimensions before the rotate, then use some trig to work out how high and wide it would be after rotating it but thats a bit of a pain if theres some function that will do it for me Thanks for any advice Andrew Tag: what's the difference between WebService & WCF Service?

I have now put a try/catch around the file copy and come up with _COMPlusExceptionCode -532459699 At the moment, it only seems to crash with .bat files.

    - 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: what's the difference between WebService & WCF Service? Tag: 137972

    - 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: what's the difference between WebService & WCF Service? 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: what's the difference between WebService & WCF Service? 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: what's the difference between WebService & WCF Service? 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.

    - Updating a collection using a lambda Hi - I have a situation where I'd like to use a lambda, but I'm not sure how.

Right now, I have this: IEnumerable<VariableCode> codes = variable.VariableCodeList.Where(c => c.Type == "MyCondition"); foreach (VariableCode code in codes) { code.IsShown = true; }//foreach I'm thinking that I can replace the foreach bit with a single lambda expression.

    - web deployed assembly I have a windows forms assembly that needs to be deployed via a webpage. This bit of code must provide a fully automated printing solution; in that it must accept a parameter containing a graphic image to print, and print it without any interaction. The issue I'm having is that it throws a security exception [Request for permission of type: System.drawing.printing.printingpermission ... failed]. This bit of code seems to work just fine if I use the print dialogbox and select the appropriate printer, and of course fails if I don't use the dialogbox. This seems to be a security issue, but I'm not sure where to look, or how to fix it. And, so as to head off a couple of other issues; I need to pass a parameter to it from the HTML page, and it has to be served by Linux. Thanks.

    - AccessViolationException with AutoCompleteStringCollection Update Hi, i have form with a text box that uses a AutoCompleteStringCollection for auto completion. Now if a new value (one not yet contained in the collection) is entered, the new value should be added to the collection.
