    - How to install ASPNET 1.1 in Windows XP IIS Hi all... i have installed ASP NET 1.1 framework in my Windows XP PC that has IIS installed. when I try to create an application using Visual Studio 2003, it says that ASP NET 1.1 is not installed. How can I do it in order to enable ASP NET 1.1 in my PC? When I go to application configuration of IIS, it doesn't list ASPX extension Thanks Jaime Tag: Speedlimit with .NET sockets Tag: 103730

    - EventLogPermissionAttribute PermissionAccess property setting acce The PermissionaAccess property is set using the EventLogPermissionAccess enumeration value Audit, Browse, Instrument, and None. The problem I have is the controlling powers want to only allow write access. The have a problem with users having read access to the application's log. I kmow this is silly, is there away to only have write access? -- Jim Tag: Speedlimit with .NET sockets Tag: 103726

    - HowTo have list of keys for RegistryPermissionAttribute I am trying to define permission attributes for several keys in the Registry at the assembly level. The documentation for the Read, Write, and Create properties states that these property values are "A list of Keys and Values with paths for [read | write | create] access". The only syntax that builds is [assembly:RegistryPermissionAttribute(SecurityAction.RequestMinimum, Read="HKEY_LOCAL_MACHINE\\System\\CurrentControllerSet\\Services\\EventLog, HKEY_LOCAL_MACHINE\\System\\CurrentControllerSet\\Services\\EventLog\\MyLog")] Is this the correct method for lists of paths? The web service is terminating with "Server was unable to process request. --> Request failed." Now I believe the Windows Server 2003 registry setting are such that I don't have permissions for reading these keys, so is the Attribute correctly working or is the list bad. -- Thanks, Jim Tag: Speedlimit with .NET sockets Tag: 103724

    - Can you please explain File Time Stamps to me? The code statements below are from the .NET framework using C#. However the question I'm asking is not specific to this environment. I'm asking for help in understanding file timestamps which are characteristic of the underlying filesystem. I'm getting all confused with the various types of filetimes; local and UTC if I understand that much correctly. FileInfo FI = new FileInfo(FileSpec); According to my understanding, I would expect FI.LastWriteTime.ToFileTimeUtc(); to be equal to FI.LastWriteTimeUtc.ToFileTime(); According to my (mistaken) understanding, the first gets the local LastWrite time and then converts it to a UTC FileTime. The second one gets the Last write time in UTC and then simply converts it to a FileTime. So why do these come out different? These two I understand: FI.LastWriteTime FI.LastWriteTimeUtc But these four, which use various combinations of local & UTC conversion are a mystery to me. Since LastWriteTime can be retrieved as either LastWriteTimeor UtcLastWriteTimeUtc Why do we need a ToFileTimeUtc at all? FI.LastWriteTime.ToFileTime FI.LastWriteTime.ToFileTimeUtc FI.LastWriteTimeUtc.ToFileTime FI.LastWriteTimeUtc.ToFileTimeUtc Are therse two simply invalid? FI.LastWriteTime.ToFileTimeUtc FI.LastWriteTimeUtc.ToFileTime Does it mean anything to pair local and Utc methods together in this manner, or is this simply illogical? Specifically, I need to compare the times for two files on separate servers. I'm pulling my information via Web Services and the two servers may be in different time zones. How can I get the last write timestamp from both files in a unified format so that I can see which file was written to more recently?

    - caching in WinForm and ASP.NET I need to adding caching capability to our application and we "get" data from our business layer code ; so initially I wanted to use something in .Net framework that provided caching and found that the "caching" mechanism was implemented in System.Web ; initially I didn't want to add System.Web reference to our business object because it was used from our web applications as well as WinForm, console applications ; so I thought I would handle the "checking" to see if the business object was running in the HttpContext and then use System.Web.HttpRunTime.Cache (if in ASP.NET) or EntLib Caching (other) ; I wanted to test something, so I created a console application and a classlibrary ; in the classlibrary, I referenced system.web and added the following shared method: Public Shared Function GetData() As String Dim strCachedInfo As String = CType(System.Web.HttpRuntime.Cache("CACHEDINFO"), String) If strCachedInfo Is Nothing Then strCachedInfo = "Hello world..." System.Web.HttpRuntime.Cache.Insert("CACHEDINFO", strCachedInfo, Nothing, DateTime.Now.AddSeconds(15), TimeSpan.Zero) End If Return (strCachedInfo) End Function and in the console application, i referenced the classlibrary and called the GetData method... Console.WriteLine(ClassLibrary1.Class1.GetData()) to my confusion, it worked?? ; I don't understand why if the classlibrary was running in the "context" of the console process did i not get an exception when calling System.Web.HttpRuntime.Cache? I read that http context was implemented using System.Runtime.Remoting.Messaging.CallContext...does this have something with why this worked? am I not understanding the caching mechanism correctly? thanks for light you can shed on this!!

    - client-side maximum string length enforcement When I was working with ASP/ADO, I would get the maximum string length by querying the system tables inside the mssql database. It wasn't the wisest thing to do, but it did let me determine the max string length for each of my textboxes, which kept me from writing updates that couldn't be successfully submitted because of strings that are too long. Now I have an ASP.NET client talking to a Web Service which gets it's data out of a MS SQL Server database. I don't really have the luxury of having the client ask the database how long it's strings are. So what's the proper way to get the string maximum length from the DB out to the client?

    - Executing 2 Threads Hello Everyone, Iâ??m having a bit of difficulty with a threading scenario. Basically Iâ??m creating 2 threads and trying to execute them one after the other. The problem is that the second thread never fires. My environment is a bit complex, and Iâ??m wondering of thatâ??s what is working against me. At the top level I have s series of windows services running which all operate independent of each other. Each of these services operates on a timer and with each tick event will try to create an instance of a new â??Engineâ?? class. The â??Engineâ?? classes that are being created further instantiate â??Helperâ?? classes. Each â??Helperâ?? supports a â??Start_Moduleâ?? method which takes no parameters. When the â??Start_Moduleâ?? method is called the â??Helperâ?? class will perform various tasks such as updating records in SQL Server and or formatting data. Each of my â??Engineâ?? classes also support a method called â??Start_Engineâ?? which is responsible for instantiating my â??Helperâ?? classes. To further complicate things, each â??Engineâ?? class also supports â??Can_Stopâ?? Boolean method which will look at of each of itâ??s child threads to see if the Engine can be unloaded from memory by the controlling Windows service. So my main problem is that once I create and start the â??Engineâ?? class it will successfully create the 1st thread, but never get around to starting the 2nd thread. I appreciate any help or advice that you can give me on this matter. Thanks, Johnathan Rossitter Here is an example of the code Iâ??m trying to make work: using System; using System.Threading; namespace Utility { public class Engine1: Engine { Thread[] MyThreads = new Thread[2]; private Helper1 H1; private Helper2 H2 public Engine1() { } private void Checker() { H1 = new H1(); H1.Start_Helper(); } private void Cleaner() { H2 = new H2(); H2.Start_Helper(); } public override bool Start_Engine() { MyThreads[0] = new Thread(new ThreadStart(Checker)); MyThreads[1] = new Thread(new ThreadStart(Cleaner)); MyThreads[0].Start(); MyThreads[1].Start(); return true; } public override bool Can_Stop() { bool RetVal = true; for(int i = 0; i < MyThreads.Length; i++) { if(MyThreads[i].IsAlive == true) { RetVal = false; } } return RetVal; } } public class Helper1:Helper { public override bool Start_Module() { //Do SQL Stuff //Do Formatting Stuff return false; } public Helper1() { } } public class Helper2:Helper { public override bool Start_Module() { //Do SQL Stuff //Do Formatting Stuff return false; } public Helper2() { } } } Tag: Speedlimit with .NET sockets Tag: 103707

    - When to use P/Invoke vs. Interop Hi, I was trying to learn more about when to use P/Invoke vs. Interop. The book I am reading says use P/Invoke when I am calling unmanaged Windows API function. Is P/Invoke only used with unmanaged API functions, or could I use Interop instead? To my understanding I could use Interop all the time but the advantage of P/Invoke is for performance reasons since it does not do type checks, etc. Am I correct?

    - Writing an Internet Explorer plugin (similar to the Google toolbar) Hi, does anyone know very roughly how to write a plugin for Internet Explorer like the Google toolbar plugin? I would like to know what programs I need to write the plugin (Visual Studio .NET???) and also if there are any decent books out there on this subject. I have trawled the web trying to find information on writing IE plugins but I can't find anything particularly useful, not even on MSDN! I've also trawled Amazon for books on this, but most seem to be not very good or just out of date. Is COM or DOM something to do with all this? Thanks, Amy.

I have a plugin system in which plugins implement interfaces stored in strongly named assembly in the GAC. The plugins, which are dynamically loaded by the host, could potentially reference any version of that assembly. Do I need to manually search through the Assembly.GetReferencedAssemblies and compare based on Name+PublicKey? And once I confirm that it implements the interface, can I only use reflection to call its members? Nathan Tag: Speedlimit with .NET sockets Tag: 103662

    - InstallUtil.exe doesn't seem to honor <probing privatepath> settin I'm using Framework 1.1 and I'm having the following problem when trying to install a service. I have my auxilary assemblies in lower directory called Shared. I have specified the following in the app.config file: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="Shared" /> </assemblyBinding> </runtime> This works at runtime but for some reason if I attempt to register the assembly as a service I get the following error: The inner exception System.Reflection.ReflectionTypeLoadException was thrown with the following error message: One or more of the types in the assembly unable to load.. It is as if the assembly's dependencies aren't being probed correctly when using installutil.exe. This doesn't seem to make sense to me since I thought the probing was done in the CLR itself.

    - threading synchronization problem I have this kind of construct: Somewhere in thread 1 ------------------------------------------------- SyncLock _objTxRxSync 'code to set some values in _objTxRxSync object If _objSignal.WaitOne(1000, True) Then 'do stuff when other thread signals Else 'do stuff when timeout End If End SyncLock Somewhere in thread 2 ------------------------------------------------- SyncLock _objTxRxSync 'code to set some values in _objTxRxSync object _objSignal.Set() End SyncLock -------------------------------------------------------------------------- The problem is that thread 1 never gives up the lock on _objTxRxSync during the 1000ms wait for thread 2 to access. The documentation states that if the second parameter for the WaitOne method is set to True, the waiting threat should give up the lock of the sync context and reaquire it when signaled.

    - System.OutOfMemoryException in EnterpriseServices We are experiencing an System.OutOfMemoryException in our application (see exception message below). We have a physical 3-tier environment. Server is Windows 2003 Server, client is Windows 2003 on Citrix, but problem also occcurs on Windows 2000 running both client and server process on teh same computer. Both configurations have sufficent free memory. The error is raised in the .NET Enterprise Services code, and is trapped in the client. The call sequence is as follows: 1-Client.DoSearch() 2-. 3-. 4-Try 5-DatasetObject = Server.Search() 6-Catch 7-ex message 8-Server.Search() 9-. 10-. 11-return DataSetObject Line 5 executes, server routine at line 8 ok, runs until line 11. Line 11 returns, and then client jumps to line 7 with OutOfMemory exception. It fails (mostly) consistently on a dataset object that is approximately 60mb, however I can make it also fail by constantly calling the Server.Search routine with smalling Datasets (i.e. 5mB) until it fails. It seems to me there is a problem in the memory management in the Enterprise Services code. I get the feeling that it is working with an upper limit of allocated memory, that is somewhat less than the memory available on the server. And maybe this has been fragmented. Any help much appreciated.

    - Why garbage collector? This might sound stupid, but I really need to know why we need another language with garbage collector? With C++ destructor, everything get destroyed without to worry about them. And because memory is not the only system resources, the concept of destructor fits well into object oriented programming practise. For instance, if Java with reference counting and without GC exists: // With destructor and reference counting try { Statement stmt = conn.createStatement(); ResultSet rs = stmt.query("SELECT * FROM table"); // Do something } catch (Exception e) { // handle exception // rs and stmt went out of scope and destroyed } // With garbage collector Statement stmt = null; ResultSet rs = null; try { Statement stmt = conn.createStatement(); ResultSet rs = stmt.query("SELECT * FROM table"); // Do something } catch (Exception e) { // handle exception } finally { rs.close(); // What if createStatement() throws an exception and rs is null??? stmt.close(); // Can you be sure that stmt is not null??? } As you can see, GC only free programmers from handling memory but force programmers to worry about other resources like file, database connection, socket connection, etc. Why don't they implement a reference counting language instead? We don't need another language like Java. Tag: Speedlimit with .NET sockets Tag: 103606

    - [Thread-Safety] Lock Object I have an application log file class which is used throughout the app, potentially by multiple threads. It's a singleton. Here're the relevant parts: sealed class LogFile { #region Singleton functionality public static readonly LogFile Instance = new LogFile(); static LogFile() { } #endregion StreamWriter streamWriter; readonly object streamWriterLock; LogFile() { #if TRACE streamWriterLock = new Object(); FileStream fileStream = File.Open(...); lock (streamWriterLock) { // lock for write memory barrier // (not sure whether this is needed) streamWriter = new StreamWriter(fileStream, Encoding.ASCII); } #endif } public void AddEntry(string text) { #if TRACE lock (streamWriterLock) { streamWriter.WriteLine(text); streamWriter.Flush(); } #endif } } Now, obviously I lock in AddEntry for atomic writing to the file. But my question is: should /streamWriterLock/ be volatile? There could be a situation where, for example, thread A and thread B are both running, and thread A accesses Instance thus creating the instance. Then thread B accesses it. Would thread B definitely see the right value for /streamWriterLock/ in this case? Tag: Speedlimit with .NET sockets Tag: 103599

    - Build Problems Hello, I have 4 aspx pages in a solution, 2 of which rely on a particular version of a third party assembly. i.e. they need to utilise properties which are in one assembly version, but not another. I was wondering if I could use a compiler directive around the setting of those properties, so the solution can build irregardless of which assemblies are present, and the system run the version of the aspx based on configuration settings derived elsewhere at run time. My compiler currently returns this error when the incorrect version of the assemblies are used: error BC30456: 'XYZ' is not a member of 'blah.blah.blah'. Anyone have any great ideas for getting this working? Any help would be appreciated Roger Tag: Speedlimit with .NET sockets Tag: 103587

    - Full .NET Framework 1.1 Service Pack 1 Installation The only way I was able to install the .Net service pack 1 was by first installing the regular .Net 1.1 framework (24 megs) and then on top of that install the service pack (10 megs)! Is there a link where I can download the full .Net 1.1 framework that includes the service pack 1 as part of the installation (one single istall)? Thanks Tag: Speedlimit with .NET sockets Tag: 103581

    - .NET 2.0 Configuration and arbitrary config files. Greetings, I have a requirement in an ASP.NET application to load configuration information from an arbitrary location outside of the web root. Specifically, the customer wants to create multiple virtual directories that all point to the same physical directory containting the ASP.NET application files. Each virtual-directory-instance should load its configuration information from a location outside of the web root, based on the name of the virtual directory it is running from. That way, they can have multiple instances of the application connecting to different databases, without duplicating all of the program files. My question is, in .NET 2.0 does the System.Configuration namespace provide a way to accomplish this? Can I just pass it the path to the config file I want it to load? Perhaps with a custom WebConfigurationFileMap or something? I looked at OpenExeConfiguration, which seems to be the only overload of anything related that accepts a path parameter, but it doesn't work. It returns a default Configuration object instead of one representing the config path I passed in. From what I can tell in the documentation, this method is expecting the path to an EXE, not the path to a config file. Or am I going to be forced to write my own configuration system because System.Configuration lacks this flexibiliity? Thanks, Joel Tag: Speedlimit with .NET sockets Tag: 103577

    - how to execute a dos command through C# ASP.net without using Proc I want to execute a .exe file through my ASP.Net C# .Net framework 1.1 application with user "X" credential. i used impersonationContext ( see notes at http://support.microsoft.com/?id=306158#4) to accomblish this. I pretty sure that this concept of imperonation works. Since Process.Start always uses the security context of the parent ASP.NET process(which is domainName\ASPNET), my impersonation is no use with Process.

    - C# Multi-Threading Lock Issue I have a server application. This application has two pieces of shared data. They are both hashtables. The untroubling hashtable holds the clients data. The hashtable that is giving me grief represents a list of all of the clients connected to the server. Periodically I go through the client list (a.k.a, the irritating hashtable) using an enumeration to make sure they are still active. The code looks like this: IDictionaryEnumerator i = ClientList.GetEnumerator(); while (i.MoveNext()) { ClientKeepAliveHandler handler = null; try { handler = (ClientKeepAliveHandler)((object[])i.Value)[1]; IAsyncResult ar = handler.BeginInvoke(new AsyncCallback(this._asyncCallBack), i.Entry); } catch (System.Exception ex) { _writeError((int)i.Key,ref ex,MethodBase.GetCurrentMethod().Name); } } Now, this iteration continues happliy along and as the asynchronous call comes back the _asyncCallBack function gets called that looks like this: DictionaryEntry clientData = (DictionaryEntry)ar.AsyncState; ClientKeepAliveHandler del = null; try { del = (ClientKeepAliveHandler)((object[])clientData.Value)[1]; del.EndInvoke(ar); } catch (Exception ex) { ClientKeepAlive -= del; Exception e = new Exception("Client to be disconnected (most likely due to inaccessibility).", ex); _writeError((int)clientData.Key, ref e, MethodBase.GetCurrentMethod().Name, "SessionId: " + clientData.Key.ToString() + ", Inner Message: " + e.InnerException.Message); CloseSession((int)(clientData.Key)); } Now, if a client cannot be reached (as in un graceful shutdown) the EndInvoke method raises an exception of "The remote machine doesn't like you" or something like that. If that happens the code jumps to the error handler, removes the delegate from the invokation list of the classes KeepAlive event and sends an email to the developers who may have random bugs in there code. Then the last line of the error handler closes the session and removes the clients data. Keep in mind while this code is executing the original code that started this may still be looping through the hashtable sending off asynchrounous calls (and is whenever I experience the problem I'm about to describe). That being said, when the CloseSession function removes an item from the Hashtable the enumeration bombs with a "oh no the hashtable has changed" error, as it should. Now that I have explained all that the question: How should I implement locking? The behavior I want is the _asyncCallBack functions should all wait until I finish looping before even being able to call EndInvoke. So I tried implementing this in many ways. lock(ClientList), lock(ClientList.SyncRoot), Hashtable SyncedHash = Hashtable.Synchronized(ClientList) with a lock(SyncedHash), Monitor.Enter/Exit, lock(SomeRandomObjectForLocking) all seem to not work. To be clear, I placed the lock statements right before ClientKeepAlive -= del in the _asyncCallBack function and right before IDictionaryEnumerator i = ClientList.GetEnumerator() in the original snipped...help?

Does anyone knows if and how it is possible to limit the speed of a
connection to some kBytes / s?

Basically network traffic limiting is made in the LSP ( Layered Socket
Provider ). More advanced programs use device drivers for that...

So no .NET here.

AFAIK you can develop an LSP or device driver endpoint ( unmanaged ) and
control endpoint ( managed ).

If you will consider device driver solution - there are already sample
drivers that can nearly satisfy your needs...

Thanks! I hoped it would be a much easier task to do. I don't know anything
about a Layerd Socket Provider but I guess I'll find out.
