    - How to display server information in a .NET application Hi, I have a requirement to display the the following information using a .ASPX webpage, basically as a test method that server is .NET ready. I am not able to find the proper controls to obtain this information in VB.NET. Any help will undoubtedly be appreciated. --> Operating System information like type, version etc., of the host Server, that's running the IIS and this webpage. --> Server protocol --> Server HTTP Port (confirming it as 80) --> .NET version --> Server path, meaning the physical directory name in full, where this .ASPX page is on the Server. Thanks in advance, Bhaskar Tag: Error sending mail Tag: 105138

    - Process.StandardOutput buffer issue Hi, I run a DOS command using a Process object. The command outputs a new line of text to STDOUT every now and then as an indication of progress. I'd like to capture that output and present it in a log window as soon as it's written. Problem: Reading from Process.StandardOutput seems to be limited to when the internal StandardOutput buffer is full. The docs state "If the size of the internal buffer was unspecified when the stream was constructed, its default size is 4 kilobytes (4096 bytes).", but I'm not really in control of creating that stream - it's done by the Process object. Is there any way I can lower this internal buffer value? Or maybe there is a better way of solving the problem? Thanks, Christopher Code snippet: Dim sOut = StreamReader Dim ps = New Process Dim s As String ps.StartInfo.FileName = "cmd.exe" ps.StartInfo.RedirectStandardOutput = True ps.StartInfo.UseShellExecute = False ps.StartInfo.Arguments = "/C " & MyDosCommand ps.Start() sOut = ps.StandardOutput s = sOut.ReadLine Do Until s Is Nothing 'This does not happen until 4K (or the entire buffer) has been read Debug.WriteLine(s) s = sOut.ReadLine Loop If Not ps.HasExited Then ps.Kill() (Btw, I've also tried to use Process.Read rather than ReadLine to specify the length of the char array I'd like to get returned, but that doesn't help as Read does not seem to read anything either until the buffer has filled up.)

    - Error 1053 - When Writing EventLog Hi I have a problem that I'm trying to track down third day or so. I have a .Net Windows Service here that used to run on the server. I have updated it a bit and now I cant find a way to make it write EventLogs on the server (it works perfectly fine on my machine and another server I was testing). It gives me error 1053 whenever the service tries to write an entry (EventLog.WriteEntry("sth", "sth"). This is my conclusion after isolating every other parts of the code. So if I have EventLog.WriteEntry("sth", "sth") in the OnStart method then it won't let me start the service. And if I have EventLog.WriteEntry("sth", "sth") in the OnStop method - it doesn't let me stop it for 5 minutes or so. I know that it might be related to the privilages, but I'm sure that this writing event was working before Any Ideas?? Thanks Tag: Error sending mail Tag: 105133

    - add icon to resource and use different sizes Hi, In my VB.NET 2005 application I want to reuse several icons in different sizes. My icons contains images of 16x16, 24x24, 32x32 and 48x48. The problem is: I doesn't always use the right size: sometimes it resizes the 48x48 image to 16x16 instead of taking the 16x16 image. Is there a way to specify which image of the icon has to be used?

    - Binary I/O and structures I have a simple structure that should be 12 bytes long (3 integers). When I use fileput(1,astructure), I discover that 24 bytes have been written. If you look at the structure in debug you see that it has a system.value object. It looks like the fileput is writing this info (which I'm guessing is 12bytes long) as well as the data. Is there some way to stop this behaviour and make it only write the data? Tag: Error sending mail Tag: 105128

    - Calculating download speed from HTTP Stream Hi All, In my app I am using the following code to read from the response stream of a web page. .. do { bytesRead = receiveStream.Read(byteArray, 0, 256); receiveLocal.Write(byteArray, 0, bytesRead); } (while bytesRead > 0) .. where receiveStream is the Response Stream from the HttpWebRequest and receiveLocal is a memory stream. Now I'm just wondering - what is the best way to work out the download speed per second. Thanks in advance... Ann Tag: Error sending mail Tag: 105121

    - Design Question. C/S Threads & AppDomains Hi all, I am developing a client/server application which has to potentially handle a very large number of concurrent users. Each connection is associated with a session object much like ASP.NET. My first wish is to be able to process the sessions in parallel. Obviously I can run each session in a separate thread however I gather that once there is a large number of users the number of threads will be too much of a drain on system resources. So I am thinking I should use a thread pool with a set number of threads and then each thread would be assigned multiple sessions. Is this the correct way of thinking? My second wish is to be able to to somehow secure each session within its own execution boundary. Basically so that if something causes a session to crash it does not take all the other sessions down with it. Is the solution to this to run each session in its own application domain? If so how would this combine with the thread approach? If say I had 50,000 users connected to a server that would potentially be a hell of a lot of threads + application domains which I assume isn't the right way to go about it. Any ideas on this would be greatly appreciated. Kind Regards, Mark Tag: Error sending mail Tag: 105120

    - Graphics Tool Hi, I really don't know the right place to ask this question... I am looking for a .NET component that will allow users to be able to edit graphics. The control would be something like paint.exe, except that the palette bar would allow me to add custom bitmaps that the user could then drag over to a base image, thereby editing it. Does anyone know if such a component is commercially available, and, if so, who offers it? Thanks. -- John Tag: Error sending mail Tag: 105109

    - copy a project with Configured assemblies Hi, We have a web application that references several strong named assemblies. This application is in a web server that had to replace. We copied the web application to another web server and registered the latest version of all the strong named assemblies. When we tried to enter in the application a binding error was thrown telling us that the assembly with name xx or one of his dependencies was not found. But the assembly was installed in the GAC and added as configured assembly with a binding policy. What seems to be happening is that .NET is searching the version of the assembly that is was originally compiled with. So if our application was compiled with version 1.0.0.0 and later it was updated to 1.0.0.1 it will search for 1.0.0.0 when searching for dependencies even when you add a binding policy to the GAC. In the new web server these old version where not installed so an error was thrown. We ended up installing all of our versions of the strong named assemblies on the new web server. My question is if this is the right way of handling this. Wouldnâ??t be better that when searching for the dependencies it would look for the latest version configured in the GAC, so that when you copy to a new web server you do not have to install al the old versions that are not used. Is this a bug? Thanx, Richard. Tag: Error sending mail Tag: 105102

    - System.Web.Mail - Bad Bug Hello, I can't see another appropriate group to post this in. system.web.mail has a bad bug in it where it is not conforming to RCF822. The old pre-dotnet CDONTS obects did not have this behaviour. The problem is that system.web.mail sends messages with naked line feeds in them rather than escaping them to be a cr and an lf. An lf on a line by itself is invalid in an SMTP message. Repro code is attached below. This message will never be able to be delivered to a qmail server (of which there are many). The code is: using System; using System.Text; using System.Web; using System.Web.Mail; namespace theEmailTest { /// <summary> /// Summary description for Class1. /// </summary> class Class1 { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main(string[] args) { MailMessage mm = new MailMessage(); mm.BodyEncoding = Encoding.UTF8; mm.To = "someone@example.microsoft.com"; mm.From = "someone@example.microsoft.com"; mm.Subject = "Test Subject"; mm.BodyFormat = MailFormat.Html; mm.Body = "Test Body\n\nEnd"; SmtpMail.Send(mm); } } } The following VBS code does cause the LF characters to be correctly escaped to a CR + LF pair prior to submitting the message to the local mail queue for delivery. Option Explicit Dim objCDONTS Set objCDONTS = CreateObject("CDONTS.NewMail") objCDONTS.To = "someone@example.microsoft.com" objCDONTS.From = "someone@example.microsoft.com" objCDONTS.Subject = "Test Subject" objCDONTS.Body = "Test Body" & chr(10) & chr(10) & "End3" objCDONTS.Send Set objCDONTS = Nothing MsgBox "Done." Any pointers on getting this fixed? David. Tag: Error sending mail Tag: 105100

    - Failures with dynamic in-memory assembly generation Hi! I'm trying to create in-memory assemblies from source using C# 2.0 from Visual Studio 2005 Beta 2. The generated assembly should have the same name as an assembly that may already exist on disk in the same directory the assembly-generating executable is running from. The code I'm using is as follows: string Code = "public class PolicyAccess "; Code += "{ "; Code += "public void GetPolicy (out string preferredConnectionType) "; [...snip...] CompilerParameters Parameters = new CompilerParameters (); Parameters.GenerateExecutable = false; Parameters.GenerateInMemory = true; Parameters.OutputAssembly = "Dummy.dll"; CodeDomProvider Compiler = CodeDomProvider.CreateProvider ("csharp"); CompilerResults CompResult = Compiler.CompileAssemblyFromSource (Parameters, new string[] { Code }); Assembly TheAssembly = CompResult.CompiledAssembly; When I execute this and want to access the CompResult, I either get a FileNotFoundException in case there is no DLL with the Parameters.OutputAssembly name in the directory. Or I get a BadImageFormatException if I just put some other file (image, text, etc.) with the required name in the directory. Or, if some other assembly with the OutputAssembly name is in the directory, this assembly gets loaded, with the types contained in it but not with the types in the Code string! In any case I never get to see the type "PolicyAccess" with the method "GetPolicy". What is going wrong here??? I was assuming that if one creates an assembly with "GenerateInMemory = true" then there would not be any files involved at all. Is there some "force assembly generation to file" option or something like that? Thanks, Andreas Tag: Error sending mail Tag: 105062

The first .NET Framework Redistributable (from now on I'll refer to as .NET) 1.0 was released several years ago, then .NET 1.1 then now we are one step away from .NET 2.0. I've found some programs (say, Microsoft Student 2006) insisted that .NET 1.1 should be installed though I have installed .NET 2.0 beta 2. When .NET 2.0 is released, would this problem disappear? Will every .NET application run happlily on machines that only have .NET 2.0 installed? I tried to run a .NET 2.0 applicatoin on .NET 1.1 and got a message box said something like "This applicatoin require version 2.0xxxx....". Now I'm just wondering what if Microsoft add an auto update feature to .NET. Instead of the previous simple error message, how about showing this kind of message? "This program requires .NET 2.0, and your .NET version is 1.1. Would you like to upgrade .NET now? Internet connection is required." [Yes] [No] Perhaps this will make the process of developers to make sure users are using up-to-date version of .NET easy.

    - Console exception after calling PerformanceCounterCategory methods I am attempting to create a custom performance counter category for use by an application I am developing. I have found, however, that after calling any of several of the static PerformanceCounterCategory methods, the next attempt to write to the Console fails with a System.IO.IOException (_message = "the handle is invalid", _COMPlusExceptionCode = -532459699, _HResult = -2147024890). I am developing using Visual Studio 2003 v 7.1.3088 and .NET Framework v 1.1.4322 SP1. The following code reliably reproduces the problem on my system: try { Console.WriteLine("Beginning Performance Counter Installation Test"); if (PerformanceCounterCategory.Exists("testcategory")) { PerformanceCounterCategory.Delete("testcategory"); Console.WriteLine("Called Delete for existing performance category"); if (PerformanceCounterCategory.Exists("testcategory")) Console.WriteLine("Performance category still exists!"); else Console.WriteLine("Performance Category successfully deleted."); } else Console.WriteLine("Category does not yet exist."); CounterCreationData ccd = new CounterCreationData("testcounter", "Test counter", PerformanceCounterType.NumberOfItems32); CounterCreationDataCollection ccdc = new CounterCreationDataCollection(); ccdc.Add(ccd); Console.WriteLine("Initialized counter creation data collection."); PerformanceCounterCategory.Create("testcategory", "Test category", ccdc); Console.WriteLine("Created category and counters"); PerformanceCounterCategory[] allCategories = PerformanceCounterCategory.GetCategories(); Console.WriteLine("Retrieved all performance counter categories"); } catch(Exception e) { int i = 1; } By commenting out various parts of the above code, I have established that this problem occurs: * In the PerformanceCounterCategory.Exists call, but only if the return value was false (if the category _does_ exist, it's fine. * In the PerformanceCounterCategory.Create call * In the PerformanceCounterCategory.GetCategories call. In all these cases, the PerformanceCounterCategory functions do actually execute successfully - the correct value is returned, category is created and categories are listed. It's only the next attempt to write to the standard output that goes splat. It looks a lot like something is closing the standard output stream... I have tried redirecting the standard output to something other than the console buffer, and got the same result. A serious side-effect of the problem is that if you attempt to use InstallUtil to run a PerformanceCounterInstaller, the IOException as InstallUtil attempts to write to the console after actually performing the installation causes the installation to be rolled back (even though the counters _were_ actually successfully installed). As an even better side effect: while using InstallUtil to run an installer that included a ServiceInstaller, ServiceProcessInstaller and PerformanceCounterInstaller, this exception tripped the debugger, then somehow deleted half the CurrentControlSet entries in the registry (everything before my custom performance category in the alphabet) during the rollback. This quite effectively rendered my development machine so much junk (vmware is your friend...). So, does anyone have any insight to offer on this issue? I really don't want to have to choose between my performance counters and my console output, much less between the performance counters and the installation! I have looked at the description for the KB830297 fix, but am uncertain as to its applicability, since we have no J# code at all. Please help! Tag: Error sending mail Tag: 105009

    - Cleaning up Isolated Storage for a specific assembly Maybe I am missing something here but there seems to be a little shortcoming of using isolated storage for storing user preferences. I realize there is a utility called 'storeadm' which I can use to remove the isolated storage for the current user (for all assemblies). What I am wanting to do (and I would expect this to be a common scenario), is that when my application uninstalls it would remove all isolated storage for my assembly only. My first guess would be to provide a command line option to my application which would remove the isolated storage data for my assembly by using a call to IsolatedStorageFile.Remove(). In an ideal world, I would go further and would like to be able to cleanup my isolated storage files for my assembly and all users. However I guess permissions play a role in this and may require relying upon an administrator to perform the uninstall. Does anyone know if this is possible? Is the IsolatedStorageFile.Remove() option the correct way to do this? Maybe someone knows a better way to deal with this problem? Thanks, Dave Tag: Error sending mail Tag: 105005

    - Seeking architectural advice Hello, I've run across an application design problem I was hoping someone may have some thoughts on. I have some .NET code (C#) that uses a third party API (using COM Interop) to convert email messages. The application has to convert potentially thousands of messages. Under some circumstances, the API freezes on a (presumably) dud email message and never returns. I don't get any notifications of the freeze. I can't have this happen in a production environment, so was trying to come up with a design to simply log these events and move on. Initially I was going to run the API conversion in a new thread, and Join() the thread with a timeout value. This appeared to be simple enough. However, the API preclude the use of free-threading - I can't pass the RCW object from the thread it was created on the to the new joined thread. I considered creating a new AppDomain to run the conversion in, and Unload the AppDomain after a reasonable amount of time. However, I'm not sure how to design this so I can create an AppDomain in the primary thread, then monitor it for some pre-determined period of time, finally Unloading it if the API (instantiated in the AppDomain) doesn't return. I would really appreciate any thoughts anyone may have. Regards, Grant Tag: Error sending mail Tag: 105004

    - LayoutKind.Explicit breaks service install I have a structure declared as: [StructLayout(LayoutKind.Explicit, Size=6)] private struct StandardFrame { [FieldOffset(0)] public byte [] frame; [FieldOffset(0)] public UInt32 integrityCheck; [FieldOffset(2)] public UInt32 sequenceNo; [FieldOffset(4)] public UInt32 dataLength; } This is part of a Windows Service C# app. I've added an installer and setup project but the install fails with "Unable to get installer types in the <name of executable> --> one or more of the types in the assembly unable to load." I've narrowed the problem down to this struct. If I make the struct LayoutKind.Sequential and remove the FieldOffset values the service installs no problem. Obviously this is not what I want, the struct is to be used as a union. This has really got me stumped, I can work around it but I would prefer to use this approach. Any clues gratefully accepted.

    - garbage collection Hello, I have a c# application that creates a timer to fire every minute using multithreading. On every minute it calls a Ping class that I made using sockets. It creates a new ping class then sets it to null when itâ??s done. I noticed every time this class gets created I see the memory keeps getting larger. I think I should add Idisposable to my ping class and dispose of the memory after the class is set to null. Can someone give me their thoughts on this and maybe an example on how to use the Idisposable class? Thanks Tag: Error sending mail Tag: 104993

    - Bypass username/password dialog when accessing remote network I am writing some code to access share folder on a remote network. DirectoryInfo dicInfo = new DirectoryInfo("remoteNetwork\shareFolder"); if (dicInfo.Exists) { //application code followed } The problem is when I ran this code, it always give me dicInfo.Exists = false even though the directory did exists. If I go to Start\Run\ and type in \\remoteNetWork\shareFolder, a dialog will pop up ask me for username/password. After that if I run the code again and dicInfo.Exists = true, which means the username/password has been cached somewhere. I also try to use WebRequest class but with no success: System.Net.NetworkCredential myCredentials = new System.Net.NetworkCredential("","",""); myCredentials.Domain = ""; myCredentials.UserName = "username"; myCredentials.Password = "password"; Uri myUrl=new Uri("file://remoteNetwork/shareFolder/New Text Document.txt"); WebRequest myWebRequest = WebRequest.Create(myUrl); Console.WriteLine("\n\nRequest to Url is sent.Waiting for response...Please wait ..."); CredentialCache wrCache = new CredentialCache(); wrCache.Add(myUrl,"NTLM", myCredentials); myWebRequest.Credentials = wrCache; myWebRequest.PreAuthenticate = true; wp.Credentials = wrCache; WebResponse myWebResponse = myWebRequest.GetResponse(); The exception is thrown at the last line. It is either access is denied or bad username or password. I also try to change "NTLM" to "Basic" with no success. If I provide username, password in a dialog as the above case, the code then work just fine. It means that the NetworkCredential doesn't even need to do its work. It is essential for my application to provide username/password behind the scene because user is not always there to provide it. Any help/ guidance is appreciated. Tag: Error sending mail Tag: 104976

    - Regular Expression Help Hi, I'm a complete newbie when using regular expressions, so forgive me if my delimma sounds stupid. I have an ASP.NET app that utilizes url rewriting. It's a simple bookstore that allows users to view books by author. The author's name is just a url encoded link tag. In my observation, author names can be quite tricky. Therefore I've written a regular expression for each possible format the author names could be in. Below is an example of author names with the regular expression included: J.K. Rowling -- (\w\.\w\.\+\w+) Dr. Martin Luther King Jr. -- (\w{2}\.\+\w+\+\w+\+\w+\+\w{2}) Nora Roberts -- (\w+\+\w+) Thomas L. Friedman -- (\w+\+\w\.\+\w+) Mark Victor Hansen -- (\w+\+\w+\+\w+) T. Harv Eker -- (\w\.\+\w+\+\w+) George R. R. Martin -- (\w+\+\w\.\+\w\.\+\w+) Nigel Da Costa Lewis -- (\w+\+\w+\+\w+\+\w+) Amiira Ruotola-Behrendt -- (\w+\+\w+-\w+) Kristie J. Nelson-Neuhaus -- (\w+\+\w\.\+\w+-\w+) I'm aware that some of them work as I've tested them, but others (the latter four) are difficult. For instance, George R. R. Martin could be written without a space between the two initials. And having dashes (-) in the names present a challenge as well. Without desiring to write each regular expression as a separate expression, I put them together using OR logic using the pipe symbol (|). So the entire thing would be like this: (\w\.\w\.\+\w+|\w{2}\.\+\w+\+\w+\+\w+\+\w{2}|\w+\+\w+|\w+\+\w\.\+\w+) and so forth. Since I'm a newbie, I'm bound to be doing something in an inefficient manner. Can the regular expressions I've shown be improved. I'd like to know how.

    - Ports required for WMI Hi, We are using an application (the application uses WMI componenets) to change the IIS metabase of Server A from Server B. There is a firewall between Server A and Server B. Couple of weeks back we tested the application and it worked fine with ports 135 and 1331 open. Now its not working any more and we are seeing that it is not working because ports 137 and 4332 are closed. (Please note that it did not require ports 137 and 4332 before). When we opened port 137, it started throwing error for ports 2255. I will greatly appreciate if anyone can comments on the followings: 1. What are the ports required for WMI connection? 2. Is there any way to specify the port numbers? Thanks Tag: Error sending mail Tag: 104969

I can't say I know this error, but can you possibly show a little more code,
helping us to reproduce the error? In addition, do you get the same error no
matter what you send? Can you send using a different SMTP server on your
network?

Hi Pablo,

the exception says that the object i already disposed.
Looks like that something goes wrong with the internal
stream to the SMTP Server. You should install a tracing
tool (e.g. YATT) and capture the stream on port 25. So will
find out where error occurs.

Cheers
Lars Behrmann
