 - processModel/memoryLimit Windows Service Can anyone tell me does the memoryLimit attribute in the machine.config also affect Windows Services. I know this does apply to ASP.NET applications, but I am unsure for Windows Services. Thank you Tag: Networking program to send multiple files for multiple clients Tag: 102278

 - Store date permanently Hi, I'm writing an activation system for a software, which allows a 15 days grace period. Now the question is... how can I store the date? It has to be kept even if the software is reinstalled, and it must not be too easy to find/delete. I could write a hidden file somewhere in the system or hide it in the registry, but if it is a limited XP account, I'm quite limited. Any genious idea!? I tried Isolated Storage, but just moving the assembly files creates a new Isolated Storage, so it's of no use. Thanks! Etienne Getting a beta version out soon...

 - .NET versions forward compatibility I posted this originally in microsoft.public.dotnet.framework.windowsforms -- but this is probably a better place... I am developing with VS 2003 -- .NET framework 1.1 I want my app to also run on .NET framework 1.0, so I define a .config file with the following: <configuration> <startup> <supportedRuntime version="v1.1.4322" /> <supportedRuntime version="v1.0.3705" /> </startup> </configuration> As a test, I am doing this on a plain-vanilla Windows app -- with a single form and a single textbox. But it does not work, on a .NET framework 1.0. Is there a way to debug a config file? Where should I look to make progress?

 - Web Service Always returns 404 Hi, I'm using VS2005 beta 2 to make an asp.net web service. When I try to run any webservice (even a helloworld example) I get a 404 error: Server Error in '/QNSEmulator' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /QNSEmulator/Service.asmx Version Information: Microsoft .NET Framework Version:2.0.50215.44; ASP.NET Version:2.0.50215.44 It started happening when i was trying to publish the website somewhere else on my local machine using the Build>>Publish ... thing. Does anyone know how i can fix this? Will uninstalling and reinstalling VS do anything? Tag: Networking program to send multiple files for multiple clients Tag: 102264

 - Creating the Double2 type Hi, I have some problems with the default rounding method of C# check an earlier post of my : http://groups.google.be/group/microsoft.public.dotnet.framework/browse_frm/thread/12ed0c44b2ffbddf/a410c5e788c35f06?l=nl#a410c5e788c35f06 To create a workaround for this problem, I wan't to create my own double type ! the 'Double2' would act like a standard double but when assinging a value to it, it will always my own rounding method to round the value to 2 decimals. Double2 d = 1.235; d -> 1.23; How can I create my own type like this ? Kind regards Frank Vandelinden Tag: Networking program to send multiple files for multiple clients Tag: 102260

 - Banker's Rounding by default, a big mistake !! Check the following example: it's a simple presentation of a ticket. double[] lines = new double[5]; //Set some VAT's lines[0] = 1.245; lines[1] = 1.246; lines[2] = 1.241; lines[3] = 1.275; lines[4] = 1.255; //Print and calc total double tot = 0; foreach (double val in lines) { tot += val; Console.WriteLine(" {0:0.00}", val); } Console.WriteLine("-----"); Console.WriteLine(" {0:0.00}", tot); Console.ReadLine(); This is the result : 1,25 1,25 1,24 1,28 1,26 -------- 6,26 Now take our your calculator (or excell if you like) an add the 5 lines manualy ! Your result wil be 6.28. -> 0.02 difference !!!!!!!!! If I give this ticket to a client he demands to now where the 0.02 euro has gone to. I know this has to do with the way C# round's its doubles (it is using the Banker's Rounding method) What i don't understand is why it's the default. To put it simple : How do I explain to someone (that is not a computer wiz), that 1 + 1 = 1.1 ????

 - Q re class layout with embedded structs A friend and fellow programmer asked, and I didn't know the answer: When a CLR class contains fields of non-scalar types (structs, say), are these structs then laid out in memory immediately within the class instance image, or are they converted implicitly into reference types and only references to instances of these stored in the class instance? 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. Is there some setting in .NET framework security or my code that I am missing? Any ideas? Thanks Tag: Networking program to send multiple files for multiple clients Tag: 102241

 - AppDomain unloading problem Hi, I have a main assembly (assy1). That assembly creates a type in another assembly (assy2). That type creates an AppDomain, load it's parent assembly (assy2) into it and creates a type in the AppDomain. Problem: when I call AppDomain.Unload(_myAppDomain), the application just crash. No exception, no message box. Nothing. Just a plain old "native days" type of crash... I really have difficulties understanding what is happening. What I'm doing is the simplest of all the AppDomain usage scenario, and yet it crash my application... Any idea? Tag: Networking program to send multiple files for multiple clients Tag: 102236

 - ReaderWriterLock acquire timeout values ??? According to the documentation for the Acquire methods on the ReaderWriterLock class: -1 Infinite. 0 No time-out. > 0 The number of milliseconds to wait. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemthreadingreaderwriterlockclasstopic.asp Does someone want to explain to me the difference between -1 (infinite) and 0 (no time-out)??? I've been using 0, but occasionally get a time-expired exception that traces back to an attempted acquire ??? I thought 0 was /not/ supposed to time out. I've switched to Timeout.Infinite (-1) to see if that fixes the problem. Regardless, I'd like to know the difference(s) between the two values.

 - custom logging sink for logging application block I have written a custom logging sink for the enterprise library logging application block (June 2005). I have been able to configure it as expected from the UI config tool (EntLibConfig.exe). I have built a console application to test it with and I am getting the following error message write to the default trace log when I attempt to use my custom logging sink. 'An error occurred while the Distributor was processing the message. Please check your configuration files for errors or typos. Verify that your sinks are reachable (queues exist, permissions are set, database exists, etc...)' This might be security related can anyone give me the answer on how to fix this? I can see from VS that the module for my custom logging sink is loaded at runtime but I am unable to break into the assembly which indicates to me that any of the 'LogSink' overridden methods are not being called.

 - 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.

 - WSE TIME synchronisation between server and client machines Hi friends, I am stuck with a problem. I have a ASP.NET(C#) based web service program which acts as the server program and a client program, both the programs residing at different locations. I am passing parameters using WSE methods, from client program to server program and viceversa. Say for ex, the server program has the system time of 10:00 AM and the client program has the system time of -5 hours to the server program. now, when i want to login to my client program, i have to pass on my username and password to the server program. In doing so, since there is a time difference of -5 hours, and i get back an error saying "Creation time can not be in the future". I put up the following code at the server program to resolve this issue..but it is giving syntax errors. <configuration> <microsoft.web.services2> <security> <defaultTtlInSeconds>86400</defaultTtlInSeconds> <timeToleranceInSeconds>86400</timeToleranceInSeconds> </security> </microsoft.web.services2> </configuration> Please let me know if there are any other methods to resolve this problem or any other configuration settings to be done!

 - code generation tool My company is thinking of using a code generation tool to generate DAL classes, Typed DataSet, Entity Objects, as well as basic WebService to access the DAL classes. As we do not have much experience about these kind of tool here, I would like to ask someone if they know any professional and reliable tool for that. I have heard of CodeSmith but I don't know if there are any other better / more complete tool. The cost is not an issue. The real issue is to find out one of the best tool on the market as once we would start to use it we would stick to it for the all enterprise application.

 - Connection as a static class Is it alright if I took a static class that wrapped around a SQLConnection object on a web application? Or should I make it an instance class? If I have a static class, would there be just one code instance of the class in the server process/app domain for all the clients/browsers? So, if a page on a particular request/context does a MyConnectionClass.Close() in its Unload event handler for the Page, would this close the connection for all clients if it were implemented as a static class?

 - 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.

 - Logging & Instrumentation App Block & ASP I'm using the June release of the logging & instrumentation block. I have two categories set up, each logs to a different sink (one goes to the application log, the other to a text file.) When I run my test code as a regular windows app, everything works fine. When it runs from within a web service, I only see the message to the event log - the text file never gets created. I don't see any errors, and the second message does not show up in the application log as it would if there were an error. What am I missing here?

 - Executing Assemblies on Shared Paths Hi, We are a software development team for a retail company, all of the programs we develop are for use internally on our network. Recently, we have moved towards thin-client technology with everyone running remote desktops using Citrix. This proves to be troublesome when deploying - only domain administrators can actually install anything onto the Citrix Server itself. Since we have a farm of about 30 servers, we have to schedule in a deployment date & ensure the Citrix team carry out the install correctly and replicate it across all servers! We've got around this in the past by deploying onto a network share that has user specific data in. Eg; \\SharePath\data\UserName\Program Files\MyExecutable.exe This ensures we are in control of our programs, we have an auto-update program that rolls out any fixes or amendments we have made to programs - there is no major delay in rolling out a new version. In the .Net framework, there are security issues when running from a shared network drive. What is the best approach to allow us to continue to run an executable from a share path, using resources located locally on the Citrix Server? We have a Strong Name key file for our department that we sign all of our programs with. If the Citrix team amend the security configuration for the .Net framework on each of the servers, can we trust all assemblies signed with our Strong Name Key so that they can run from network shares (as in .7 of .NET Framework Enterprise Security Policy Administration and Deployment FAQ?) Is this the best approach to allow us to continue share deployment? Thanks Tag: Networking program to send multiple files for multiple clients Tag: 102130

 - Running Two Visual Studios at the same time, Dll's are being locked I am having a problem when running two Visual Studios at the same time. I know it is not a good idea to run Two Visual Studios at the same time but in this case I have to (Unless you have another way of debugging a webservice and a Client at the same time) I am trying to debug a Webservice in the one Visual Studio and in the other Visual studio I am debugging the client application. This all works fine for a while until one or more of the dll's that the WebService references gets locked. This dll is also referenced from one or more of the projects on the client app. Both of the Visual Studio program's compile there solutions just fine. Its when I try to run the webservice that I get a configuration errror and it tells me that access is denied to one of the dll's. This is not always the same dll as it randomly locks these files.. The only way I can recover from one of the dll's being locked is to restart my computer. This is slowing dev time down. I am looking for a way to unlock these dll files so that I dont have to restart my computer to get past this.

 - Clone without copying event handlers I am cloning an object using MemberwiseClone plus some code of my own to perform a deep copy. This is fine except MemberwiseClone copies event handlers which I don't want. How can I remove all event handlers from an object? This needs to be done from within the object itself. RemoveHandler is not an option as I have no knowledge of what handlers have been installed. I have seen posts sugesting something like: [Delegate].RemoveAll(ChildAddedEvent, ChildAddedEvent) where my event is called 'ChildAdded' This seems on the right lines and although it compiles, it does not have the required effect. Ideally I would like to remove all event handlers attached to the object without having to name them individually. Tag: Networking program to send multiple files for multiple clients Tag: 102116

 - What's .NET best IPC solution? Hi all, I have a couple of existing components that need to communicate with each other, one is a server that is always on. The other is a COM plus component that is called every other time that send a message to the other application (using a custom made messaging system). At this time each call takes 100 ms, so, If I make 10 calls I loose a full second (this is bad for our architecture). So, to make the communication between the components faster I'm thinking in some kind of IPC communication between the COM plus component and the server. They're both made in .NET. So, I'm asking you, what's the best IPC solution in .NET?

 - Problem resolving assemblies Hello, I am facing an issue I cannot easily solve. I am writing a non-managed C++ application that I want to be extensible using plugins. The goal is to let people write plugins in any language they want including C# (but also C++, Delphi or whatever...). The way I am doing things right now is to write a managed C++ wrapper that implements the callbacks required by the application to be recognized as a plugin and uses code written in C# and provided as a DLL. I therefore have two DLL's for one plugin: the C++ wrapper and the C# real stuff. This works fine except for one issue: it would be nice to place in a "plugins" directory next to the application binary. Ideally I should therefore have the following layout (final version also has each plugin in its own subfolder of the plugins directory but let's keep it simple for the moment): -- app.exe (unmanaged C++) -- plugins ----- wrapper.dll (managed C++) ----- plugin.dll (C#) The problem is that wrapper.dll does not resolve the plugin.dll assembly unless I put it next to app.exe which is not very nice. I tried to solve the issue by using AppDomain::CurrentDomain->AppendPrivatePath("plugins"); in wrapper.dll but this does not work neither. Please note that my AppDomain's BaseDirectory is the folder of app.exe and not the plugins folder so it seems like I get the AppDomain of the application and not the one of the DLL although app.exe is not managed... I tried a lot of things but cannot reach anything working. Again, there is no problem mixing all these languages (C# code wrapped by managed C++ code for a unmanaged C++ application) as if I put plugin.dll besides app.exe everything works fine.

 - Timers and Services Hello, I've written a windows service and so far what it does is browse to a shared directory on an extranet. Check to see if any files exist in this folder, if any do, the service downloads, processes and then uploads a response file back up to a different shared folder. My Question: I would like to be able to start this service at 4am every day(I know the download files won't be there until then)...then I want the service to check for the files every say 20 mins until say 6am and then stop chcking for the files until 4am the next day.

 - Printer Spool crashes approx. once a day We have a Win 2003 Server with shared printers installed on it. Approx. once a day the spool service crashed without any reason. In the event-log we get a message, that the spool has crashed. Due to the properties of the printer spool the service is started again. But then it crashes several times, until we delete all SHD- and SPL-Files in the spool directory. After that the spool service runs for approx 24 hours. The print-jobs, which creates the SPL- and SHD-files are pure ASCII-textfiles, which are sent from Client-PCs to the shared printer on the server. Has anyone an idea, why the print spool crashes?

hi

I'm writing a small windows service for sending multiple files for multiple
clients when the request is got from the client . i need suggestion to
implement this concept

would you prefer multiple ports to be used to send the files at a time to
the requested clients using multithreading?
