    - Hashtable thread safety? It doesn't seem completely clear to me which operations I can perform while continuing to be thread-safe on a Hashtable. Consider this scenario: Hashtable 'table' contains the following: table[1] = 1 table[2] = 2 table[...] = ... table[Int32.MaxValue] = Int32.MaxValue The following threads are now running against that same table Thread 1: for( int i = -1; i > Int32.MinValue; i-- ) { table.Add( i, i ); } Thread 2: for( int i = 1; i < Int32.MaxValue; i++ ) { table.Remove( i ); } Thread 3: while( true ) { IList list = new ArrayList( table.Keys ); foreach( int number in list ) { Console.WriteLine( number ); } } Obviously this is unusual, but it's something like what I actually have, and I want to know whether or not this is thread-safe or if I need to provide some synchronization.

    - Posting values between pages That ASP.NET pages post to themselves, how do pages share information amoung themselves? As in, if my index.aspx has to post data to nextpage.aspx, how does it happen? Is it left to the developer to persist relevant control values in a state dictionary such as Session and read them back in the target/destination page nextpage.aspx?

    - SocketException ??? Hi. I have some quite unusual situation at which SocketException is thown while connecting a socket. Generally the aim of application is processes data and send results to a specified IPEndPoint. Since theres small amount of time for processing and sending large amount of data it is logical to split whole process in to few threads. One thread processes data and other sends it. The problem occures when user sets too little time for doing that. At first the thread works fine for about a minute or two, results are being received on another machine event when the speed of whole process is considered to be critical. And then just like that, exception SocketException is thrown while connecting to an IpEndPoint with message that might be translated as "It is usually allowed a single use of socket address". As seen below socket is being shutdown and closed in the end. And it seems like theres absolutely no reason for that exception to catch. Any propositions? Thank you. Error code of exception is 10048 private void Operate() { while (/*There is data to send*/) { Socket socket = null; try { socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); socket.Connect(ipEndPoint); <--------------------------------------------------------------------------Exception: SocketException thrown here !!!!!!!!!!!!! NetworkStream stream = new NetworkStream(socket); BinaryWriter writer = new BinaryWriter(stream); Scan[] scans = null; lock (queue) { scans = queue.Dequeue() as Scan[]; } for (int i = 0; i < scans.Length; i++) { writer.Write(scans[i].Azimuth); socket.Send(scans[i].Data); } if (socket.Connected) { socket.Shutdown(SocketShutdown.Both); } } catch (SocketException e) { msp.Engine.Paused = true; if (MessageBox.Show(msp.Window,"Error occured:\n" + e.ToString() + "\n\nStop process?","Warning",MessageBoxButtons.YesNo) == DialogResult.Yes) { msp.Engine.Launched = false; } else { msp.Engine.Paused = false; } } finally { if (socket != null) { socket.Close(); } } } Tag: System.Net.HttpWebRequest - help Tag: 102345

    - SqlException: Unknown Error I have some code doing a very simple select "select bonusid from game where gameid=@gameid" that works about 98% of the time, but somewhere around two percent of the time it throws an exception. If I go through the sqlerror's in the exception all it has is the following: Index #0 Message: Unknown error. LineNumber: 0 Source: .Net SqlClient Data Provider Procedure: Not very interesting is it. I've checked that the input is valid and I have no problems running the same query manually. I also have yet to find a consistent way to recreate this error but my clients are having no problems doing it fairly frequently with no rhyme or reason that I can tell. Although there are many clients simultaneously using the server they share one database connection but I am very careful to only use the connection through a wrapper class that Lock()'s the database connection. I'm really lost on this one, has anyone else seen this? I could find next to nothing on google/google groups. Lloyd Christopher SLOW30 Tag: System.Net.HttpWebRequest - help Tag: 102325

I had runned without results the installutil for each assembly, I had compiled in command line the source code of these blocks in the server and i dont had results, i had do everything possible (but not install the Visual Studio 2003), and i dont have positive results. Hey Microsoft guys, what is the problem with yours??, Keep it simple, why the DAAB had worked so good, so easy, and with that enterprise library everithing had changed, and you had send us a stupid problem.

    - server side http for a non-web server I'm evaluating using http to carry data between a client and a non-web (C#) server application. This sounds great as the browser already has an http implementation and http is an open protocol. I was expecting to find a server piece that implemented the server side without requiring a full web server. I've looked around and found http.sys which sounded ideal but which doesn't seem have a C# API until Framework 2.0. Is anyone aware of either some kind of a C++ wrapper for http.sys or an alternate http implementation? If not, I can fairly readily build a wrapper on top of existing TCP functionality but I believe in reusing software when possible. I could also introduce IIS and create an ASP.NET "proxy" that could take http POSTS and relay them in the existing TCP format. Thanks Mike Tag: System.Net.HttpWebRequest - help Tag: 102317

    - asynchronous logging with enterprise library logging application block. I am trying to use asynchronous logging using MSMQ and I have configured the properties as defined in the help (see below) I don't understand where the property 'MsmqPath' is in the app.config for MSMQDistrbutor.exe is it meant to be an aplication settings or an enterprise library setting in the app.config? I have tried creating an application setting value for it but it still fails to write to the logging destination? Also is this meant to be registered as a service? To choose asynchronous logging. 1.. In the Enterprise Library Configuration Console, expand Client Settings, right-click Distribution Strategies, point to New and then click MSMQ. 2.. Select the strategy and then specify the QueuePath for the strategy. 3.. Select Client Settings, and then modify the DistributionStrategy property to select the MSMQ distribution strategy you created. 4.. Open the MSMQDistributor.exe.config file with the Configuration Console, located in the directory containing the file MSMQDistributor.exe. Modify the MsmqPath property of the MSMQ Distributor Service to match the QueuePath property of the MSMQ distribution strategy you selected in step 2. This distribution strategy will be used for all messages that are not filtered out. Note Do not use the In Process distributor strategy and the MSMQ distributor strategy to log to the same flat file sink. Using both the In Process and MSMQ distributor strategies with the same flat file sink may result in simultaneous attempts to write to the same file. This will result in failure due to the file resource being in use by another process. Has anyone got any ideas? I followed the instructions below to allow for an MSMQ not registered with AD. http://mvwood.com/blogs/blog/archive/2005/03/04/321.aspx Cheers Ollie Riches Tag: System.Net.HttpWebRequest - help Tag: 102316

    - Monitoring the existence of multiple files What's the best way to monitor an arbitrary set of files? In a program like a CD burning app, you've got a an explorer-like file system listview that you pick your files from and a listview for the CD compilation. If you populate the CD listview with 100 different files from 100 different folders, is there a good way to monitor any changes to the files in that listview (deletions, renames, moves, etc.)? This is mostly a GUI thing. I can easily check the existence of the files just prior to performing any operations on them, but I'd like to provide realtime feedback to the user so that they know when one of the files they've chosen is unavailable. I know there's the FileSystemWatcher class, but I suspect it's unwise to create 100 FSWs, each monitoring one file per directory. Tag: System.Net.HttpWebRequest - help Tag: 102314

According to him, the reflection APIs leave the impression that the latter takes place, whereas the SOS documentation suggests the former. To clarify, I'm referring to fields of types that are not usually reference types (structs) as opposed to arrays and strings that are of course always stored by reference.

    - Bulk Import - Thread was being Abort I am facing a unique problem where i am reading an XMl stream(8000 records) using open XML into SQL server > The problem is that whenever i execute the stored procedure it starts inserting data but suddenly stops at about 1 min 45-50 secs time. The import stops and the error is "Thread was being aborted". The whole stuff works fine when i connect to the database server from local machine. The database server is located at a remore place and the live application resides in the same place as of the database server. I get this problem when i try doing import logging in to the live server. i dont get this problem when i try doing this locally to the remote database server Settings : IIS6.0 and ASP.NET, SQL Server please suggest if there are any web server based settings which are forcing the import to time out.

    - Cannot receive data across socket connection by .NET app I have a .NET app that connects to a third-party server on a socket and sends data. This works with a test server on the local network, but does not work across the frame connection to the third-party server. They see a connection, but never see any data coming across. This works with Win32 app using winsock. However, if I use [DllImport] and call a Win32 dll that uses Winsock from my .NET app, it does not work.

    - strong name using al.exe and csc.exe I'm very much a beginner with C# and the .NET Framework environment, and am writing and building C# programs using the command line CSC.EXE compiler. What I'm trying to do now is try out some of the evidence options and the security policy settings. Code Signing and using this via certificates and Publish evidence is working fine, but I'm a bit stumped by strong naming at the moment. I've created a key pair using sn.exe, and read that I sign with this to an assembly before it's built (so not to a completed .exe). This seems to be the way to go from what I've read: AL.EXE /out:testapp.exe testapp.netmodule /keyfile:keypair.snk So far I've been using /target:winexe in CSC.EXE, so don't have the module files AL.EXE wants. I tried changing the CSC.EXE command line to: CSC.EXE /target.module /reference:... testapp.cs This allowed AL.EXE to complete without error messages, but the resulting .EXE says it's not a valid Win32 executable. Can anyone point me in the right direction to getting a valid Win32 executable that is strong named, using only the command line tools of the SDK? Danny.

    - Otpimization of vb.net application using NTD Hi All, We had developed a .Net application which has the following environment Uses the No touch deployment concept Uses framework 1.1 on client and server machine, Visual studio 2003, Sql server 2000, Deployed on a windows 2003 box. Reporting is done using Crystal reports 10 A third party component grid from DevExpress has been used on all the forms in the application. And the No touch deployment exe uses webservice hosted on the web server which call the .net dlls for communicating with the database which is hosted on its own machine. We use SOAP for validation. All of my tables have indexes on them. Application uses customized SOAP headers to communicate with the webservice. The application is deployed over the internet in CT and the client is using it in Houston over the internet using a T1 connection. Most of the times it is ok, but at time the performance of the application, which depends a lot on the speed of the internet connection is very slow. Very soon we are going international on this application which mean that there would be clients in Europe, Asia who would be using our application hosted in CT. My question is considering this environment the application is developed and deployed in, can any one suggest ways of optimizing this .net application, either database wise or .net optimization or configuration. I know there is already a latest framework out there, 2.0(if I am no wrong), can any one give me reviews on it and also tell me if in any way it optimize the application to run any faster.

    - System.Treading.Timer stops firing events Hi everybody. Recently I ran into situation with System.Threading.Timer in my ASP.NET application. I reinstalled Windows on one of my servers and got timers stop firing events after while, they just stop functioning one-by-one. Here is detailed explanation. I run application on 2 dedicated Win 2003 servers. Server A serves about 1000 active simultaneous users (150-200 aspx page requests per second), Sever B serves about 400 users (80-100 aspx requests per sec). Application is the same. Machine.config is identical. maxWorkerThreads and maxIOThreads bumped to 40. minFreeThreads = 8. There are about 25 static timers throuout the application and there are some dynamicly created timers. Recently I realized that hosting company did not install SP1 for some reason, but applied critical hotfixes. I asked to reinstall OS on the servers, so far they did it on server B. Now, after installing Win 2003 on server B, with SP1 and all recent updates, and installing my application there, I'm getting my timers stop working. Possible exceptions in timer events are silenced. Logging shows that timers work normally for a few minutes and then next event just never happens. If I force timer by calling it's Change method, it works for a few minutes and then dies again. Below is simplyfied code sample and a result log. Again, it works fine on Win 2003 without servicepack, and does not on Win 2003 SP1. The timers are not accessed from any other place, they are being created on app init and then managed in Change method in timed event (see code). Eventlog does not show any threads being terminated. Also, I noticed that even though .Net version is the same on servers A and B (1.1.4322.573), the behavior is a bit different. In particular, on server A bad viewstate causes exception with message "The viewstate is invalid for this page and might be corrupted." while on server B exception message includes as well client IP, requested URL, and viewstate. Does anybody have any idea what all this about? Any hint? For now I had to shut down server B and let server A handle all the work. I've had similar problem with System.Timers.Timer before. Since I switched to System.Threading.Timer, it was gone. And now... ups... Code sample. Global.asax.cs namespace VR { public class Global : System.Web.HttpApplication { private Common.AppTimers appTimers; protected void Application_Start(Object sender, EventArgs e) { appTimers = new Common.AppTimers(); } } } vrTimers.cs using System; using System.Threading; namespace VR.Common { public class AppTimers { private Timer tmTimedWork; static private AppTimers appTimers; public AppTimers() { try { VR.Logger.Log(VR.enumLogs.Logic, "Init timers"); tmTimedWork = new Timer(new TimerCallback(OnTimedWork), null, 7000, 10000); appTimers = this; } catch(Exception ee) { VR.Logger.Log(VR.enumLogs.Logic, "AppTimers(): " + ee.Message); throw; } } public void OnTimedWork(object source) { VR.Logger.Log(VR.enumLogs.Trace, "OnTimedWork begin"); try { tmTimedWork.Change(120000, 600000); lock(tmTimedWork) { long period = SomeClass.SomeStatic() * 1000; tmTimedWork.Change(period, period); VR.Logger.Log(VR.enumLogs.Trace, "OnTimedWork end "+period.ToString()); } } catch (Exception ee) { tmTimedWork.Change(5000, 5000); VR.Logger.Log(VR.enumLogs.Logic, "OnTimedWork: "+ee.Message); } } } } The log looks like this: 8/31/2005 4:37:46 AM: OnTimedWork begin 8/31/2005 4:37:46 AM: OnTimedWork end 1000 8/31/2005 4:37:47 AM: OnTimedWork begin 8/31/2005 4:37:47 AM: OnTimedWork end 1000 8/31/2005 4:37:48 AM: OnTimedWork begin 8/31/2005 4:37:48 AM: OnTimedWork end 1000 8/31/2005 4:37:49 AM: OnTimedWork begin 8/31/2005 4:37:49 AM: OnTimedWork end 1000 8/31/2005 4:37:50 AM: OnTimedWork begin 8/31/2005 4:37:50 AM: OnTimedWork end 1000 8/31/2005 4:37:51 AM: OnTimedWork begin 8/31/2005 4:37:51 AM: OnTimedWork end 1000 8/31/2005 4:37:52 AM: OnTimedWork begin 8/31/2005 4:37:52 AM: OnTimedWork end 1000 8/31/2005 4:37:53 AM: OnTimedWork begin 8/31/2005 4:37:53 AM: OnTimedWork end 1000 8/31/2005 4:37:54 AM: OnTimedWork begin 8/31/2005 4:37:54 AM: OnTimedWork end 1000 Dmitry.

Now I am trying to complete and submit a form using HttpWebRequest
I have the form name,action,method etc
I also know how to use the Method property and GetRequestStream
of HttpWebRequest.
What I dont know is how to construct the script correctly.
When/if I figure out the script do I just use .write on the request stream?
Can you help on the scipt etc
Hope so

Thanks much
