    - .NET Runtime Optimization Service causing Web Service to stop responding?? I'm hoping somebody out there can help me. I have developed a web service in C#.Net 2.0 and have it running on a Windows 2003 Server (Standard Edition). The .NET Runtime Optimization Service is running on the server every 5 minutes and then every morning the Web Service becomes unresponsive. I'm not really sure where to even begin to try to fix this issue. Thanks in advance for any help / leads you can give. Tag: Group Policy Tag: 121999

    - Active Directory and DirectorySearcher Filter I am using DirectoryServices to get all groups and all users from active directory. Now I want to use the filter to limit the groups and users. I would like to remove the builtin groups. I use the code below but the built in groups are still there. The main question is how do I construct the filter strings. The code gives me the properties and their values. Do I use these properties and values in the filter or is there other information I am missing. Code: Dim strDomPath As String = "LDAP://cd2k3domtest/DC=CDTESTDOM,DC=adwaresystems,DC=com" Dim dirEnt As New DirectoryEntry(strDomPath) Dim dsgroups As New DirectorySearcher(dirEnt) dsgroups.SearchScope = SearchScope.Subtree dsgroups.Filter = "(&(objectCategory=group)(!distinguishedname=Builtin))" Dim srGroupsCol As SearchResultCollection Try srGroupsCol = dsGroups.FindAll() Catch domE As Exception Dim str As String str = domE.Message End Try Dim objarray() As String ReDim objarray(35) Dim arrGroup As New ArrayList Dim srGroups As SearchResult For Each srGroups In srGroupsCol 'will get all property names that are available srGroups.Properties.PropertyNames.CopyTo(objarray, 0) Dim i As Integer For i = 0 To objarray.Length - 1 Try Dim strPro As String = CType(objarray(i).ToString, String) Response.Write(strPro & "  " & srGroups.Properties(strPro).Item(0).ToString & "<br />") Catch End Try Next Response.Write("*************************************************************<br />") Next -- Jerry Tag: Group Policy Tag: 121997

    - Question abt Password Expiry Hi I have to implement password expiry in my application, in the same way as Windows does it. If a user's password at Active Directory is expired or reset, a window is displayed that allows him to change his password. The problem is that if password has expired, then DirectoryEntry.Invoke("ChangePassword", new object[]{old, new}) throws an exception with the message "Logon Failure: Incorrect user id or password." Another complication is that I cannot pass the passwords in cleartext. Do let me know what can be done about this. This is urgent Thanks and regards Vikas Manghani Tag: Group Policy Tag: 121991

    - Error decoding ISO character 147 Hi I have a byte-array, in which one of the bytes has the value 149 (hex95) which represents a dot ( ? ). The same character has the unicode value of 8226 (hex 2022) But when I try to decode the byte-array into a string, that character is not converted into the correct value. If I use the following code: byte[] b = new byte[] { 147 }; char[] c = System.Text.Encoding.GetEncoding("ISO-8859-1").GetChars(b); c now contains the character value 147 - which is an illegal unicode value. What am I doing wrong (actually asp.net is doing it wrong as well, because if I enter that character in a text-field, then the wrong value is stored in the database. So the character is not properly decoded when the form is posted to the server) Regards, Pete Tag: Group Policy Tag: 121989

    - Interesting problem with SmtpClient in background thread I'm experimenting with the SmtpClient class in c# and I have run into a knotty problem. I'm using the ThreadPool.QueueUserWorkItem to queue a delegate which creates an SmtpClient and attempts to send an email. Basically, If I try and create a new SmtpClient object in a thead managed by the threadpool the application exits without an exception being thrown/caught. However, if I create an SmtpClient in the main program the pooled thread can create the SmtpClient but it then blows up trying to send an email.... Anyone got any ideas..... I'm using the following code public class MailServer { public void QueueMail( string from, string to, string subject, string body ) { MailMessage m = new MailMessage( from, to, subject, body ); ThreadPool.QueueUserWorkItem( new WaitCallback( MailProc ), m ); } static void MailProc( object state ) { SmtpClient clt = null; try { clt = new SmtpClient( "InternalMailServer" ); // <<---- The application blows up here without being caught !! } catch ( Exception e ) { Console.WriteLine( e.Message ); } try { clt.Send( (MailMessage)state ); } catch ( Exception e ) { Console.WriteLine( e.Message ); } } } class Program { static void Main( string[] args ) { // SmtpClient clt = new SmtpClient( "InternalMailServer" ); // <<--- Is I uncomment this line it blows up at the Send() above....

    - Problems when writing a SMTP client and talk with the hotmail Hi, First, I am not trying to talk to hotmail through the SMTP straightly. I am trying to write some codes to send emails through a SMTP server. I wrote a C++ version using pure socket programming and SMTP protocol, a VB version using CDO and a C# version using System.Net.Mail. Now all of them works great with any email account but hotmail. So here is the C# code: MailAddress from = new MailAddress("Z...@CCC.com", "XXX"); MailAddress to = new MailAddress("S...@hotmail.com", "YYY"); MailMessage mail = new MailMessage(from, to); mail.Subject = "Test only, please don't block me"; mail.Body = "Test only, please don't block me"; SmtpClient client = new SmtpClient("xxx.xxx.xxx.xxx"); client.Send(mail); here is the VB Code: Set objMessage = CreateObject("CDO.Message") objMessage.Subject = "Test only, please don't block me" objMessage.Configuration.Fields.Item _ ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "xxx.xxx.xxx.xxx" objMessage.From = "Z...@CCC.com" objMessage.To = "S...@hotmail.com" objMessage.TextBody = "Test only, please don't block me" objMessage.Send I wouldn't put C++ code here because it's too long. 1. I can use Outlook to send out email (on the same machine where my code runs) and hotmail will receive it with no problem. So I know my SMTP server was not blocked by Hotmail. 2. My SMTP server doesn't require authentication, I know it's bad. But I can't change that. 3. Somebody told me that I would need some strange header to make the hotmail like my email. Therefore I set up a sniffer and get all headers which are used by Outlook. I used all of them in my C++ code but it still doesn't work. Now this hotmail problem drives me crazy and I have wasted 4 hours on it with no clue. Can anybody help me out of here? Thanks Ou P.S It's a little bit ironic to see that MS' product doesn't work well on its own product. Tag: Group Policy Tag: 121968

    - searching byte arrays and RTFreaders Hi Does anyone know of a .net technique that can quickly find a particular byte value within a byte array and return its position, much as instr does for strings in VB.NET? I'm writing my own custom RTFreader by having my class inherit the .NET System.IO.BinaryReader. My goal is to have a stream reader available in .NET that returns the text portion of an RTF file stream - less any formatting. Being a binary reader, my custom reader loads n-bytes into a byte array. It then loops through this array and only returns qualifying bytes to the calling routine. Some RTF files contain embedded graphics and objects, and these can be made up of hundreds of kilobytes of data. When my custom reader encounters one of these blocks, it spends alot of time looping through the object's bytes just to bypass them. This can cause a significant delay for my reader to return from a call. To speed things up, I thought I could calculate the offset to the end of a block. Each object and graphic in an RTF file is described by a \pict or \object group. These also have tags that describe the object's dimensions. I thought I could take the dimensions, multiply them together and divide that by 255 (because the object data is byte-64 encoded) and multiply by two (because each encoded byte is represented by two hex digits - A5, EF, FF etc) to give me the length of the RTF file's encoded block. This would have worked, except that the width and height dimensions in the RTF file are in twips and not pixels. So, I'm back to looping through the byte array to find the delimiter that marks the end of a block. Is there a facility in .NET that can perform this search at machine language speed and return the location of the found byte? I heard that .NET's regex class might be able to do this, but doesn't that also only work with strings? Andy Tag: Group Policy Tag: 121952

    - Is there a way we can send a feature request for Visual Studio? Hi, Is there a way we can send a feature request for Visual Studio? When using 'Refactor-->Encapsulate Field', I'd like to have an option for the references not to be updated anywhere in the project. It would be very useful for me (and probably others too) because I use this feature to generate my properties from my member variables. So I type all my member variables and then take them one by one and encapsulate them... When the project is small it's quick and efficient, but when the project becomes bigger it can take many seconds and sometimes minutes because it searches in all the assemblies of the solution to update the reference to a private variable that is not used anywhere because I just created it. Moreover, it would be nice to take a block of member variables and tell Visual studio to encapsulate them all. It would save a lot of time (and money too). So to reiterate my question : Is there a way (or place) we can send a feature request for Visual Studio? thanks ThunderMusic Tag: Group Policy Tag: 121941

    - Problem with timeout in TransactionScope Hello, I'm porting my application from ServicedComponents to TransactionScope objects. One of the most fun features of new tech is that it allows transaction timeouts more then 10 minutes. My application has many layers and using SqlTransactions is not convinient. As I undestand if TransactionScope is created with TimeSpan.Zero timeout then transaction manager doesn't control transaction time. But actually the transaction is aborted after 10 minutes timeout set in Machine.config. It is true for both SQL 2000 & SQL 2005. If transactions were created explicitly via CommitableTransaction class, this limitation didin't appear ( but only for SQL 2005, SQL 2000 transaction still were aborted ). After explanation of System.Transaction code via Reflector utility I found that TransactionScope always checks timeout via TransactionManager.ValidateTimeout method while CommittableTransaction doesn't. I guess the the problem can be resolved by changing maximalTimeout in machine.config but it is not applicable in the concrete case. I'm wondering is such behavior of TransactionScope designed? Can I rely that CommittableTransaction preserves this behaviour in the next versions or .NET? Thank you for your attention. Vladimir. Tag: Group Policy Tag: 121937

    - GC problem with large object - .net 1.1 Hello, I have an applications witch works with bitmaps. Such bitmaps are in windows (forms) sizeable. Each time it is neccary to allocate new bitmap with any size-step, because the bitmap is generated. So there is the following situation under .net 1.1 If the window (bitmap) is sized for exampel 10 bitmaps are generated and disposed in 2 seconds. Because the GC does not make garbage collection directly, this costs 10 MB ram instead of 1. If it is exreme, an application which needs realy 10 MB - you see in the taskmanager 50 MB. But this is the first layer of the problem. Now some time later, maybe the GC makes a garbace collection. Now GC-Memory has 10 MB used and 40 MB free. BUT the GC does not give the memory back to the system. (sometimes GC gives a little back to the system, but not all). Means: for a long time you see 50 MB RAM resources used in the tasks manger, what is not the reality, it's only 10 MB. This problem is very hard, because customers see this in the task manager und do not buy the product. So question: Is there any way under dot net 1.1 (.net net 2.0 is absolute impossible in the moment because of many reasons), to reduce the shown used Memory, which is wrong in the taskmanager for this app. Means is it possible to solve the problem when the bitmap is sized that memory is not accumulated, because with each new bitmap the old is disposed. I think there will be no solution under .Net / C#, but would be fine. But also a solution using C++ / unmanged code would be nice. (for the allocation of memory of the bitmaps only).

If you check the SelectedIndices property of your list view within the SelectedIndexChanged event, and the user Shift-Selects a range of items in the listView, the number of selected indices is always zero. The returned list of selected indices is correct if the user uses the ctrl-select, or just simple selects from the list. This happens when the view property is set to "Details".

    - Are named pipes quicker than just reading and writing to files? Hi all, I've been looking into doing some interprocess communication and have been reading about named pipes. Everyone seems to indicate that if the processes are either on your local PC or at least on your local LAN AND your messages are reasonably small (under a kilobyte) - then named pipes are the right solution. But all of the implementations I've seen seem to just be writing and reading to a file. Is named pipes just a marketing term for regular old file I/O. Here are the two implementations I've looked at: http://www.codeproject.com/csharp/DotNetNamedPipesPart1.asp http://i-d-e-a-s.blogspot.com/ I think the second URL provides a more concise implementation so that I can more easily use the code myself in my own project. As opposed to the first one - which while well architected in design all comes with lots of classes, interfaces and even a prebuilt dll to which you don't have the source. Am I gaining anything by using the implementation in the second URL over just using a regular write and read to and from a file? If not, is there some inter-process code that is relatively concise that would be superior to just reading and writing to a file? Thanks, Novice Tag: Group Policy Tag: 121874

    - Async UI Calls Block on Dual-Core CPU, work fine on Single Core. Why? I am using the code from this MSDN article http://msdn2.microsoft.com/en-us/library/bz33kx67.aspx Everything worked great on my single core CPU laptop. I then tried to run the .exe on my Dual core Pentium-D at work. The UI becomes unresponsive while the background thread is running. When I go into task manager and change the CPU affinity from 0,1 to just 0, the UI becomes responsive again. Please keep in mind that made the loop longer so that I have time to observe the blocking. Anyone have any ideas? Thanks CZ Tag: Group Policy Tag: 121867

    - Async activities from class not derived from Control I want to create a utility class which is defined as follows: public Class MyDataReadingClass { ... } In that class I want to encapsulate all the logic for performing certain SQL Server queries and have the result set accessible from my parent, which will always be a System.Windows.Form object. My problem is that since my class is not derived from Control, I do not have access to Invoke() in my async callback handler, where I would normally pass my SqlDataReader via Invoke to a safe place from which its contents can be accessed without synchroniziation issues. It seems silly to be deriving my utility class from Control when it is not really a control, but I want to be able to create instances of my data reading utility class in different places in my applications. Can someone please help? Thanks in advance. Valerie Hough Tag: Group Policy Tag: 121861

    - System.ComponentModel.BackgroundWorker runs DoWork handler twice Hi, Using Visual c# 2005 express, I have a Form which utilises a button click to start a BackgroundWorker thread. The thread calls a Soap proxy class, derived by web reference, to consume a web service on a server. Each time it runs, it runs the DoWork event handler code twice! I've tried adding a second event handler in to the DoWork event. That one only ran once whilst the Soap service consumer one still ran twice. The code snippet below is the actual code for the button click, and event handler codes, with the following notes: - all the methods below are part of the Form class - SoapClass represents the web reference derived class. - the actual winform is a simple form with a username text field, password text field and connect button. it's very simple so I thought it a waste of space to post all the form supporting code. Any clues as to why this would happen? Cheers Ian <code> private void InitializeBackgoundWorker() { this.backgroundTask.DoWork += new DoWorkEventHandler(backgroundTask_DoWork); this.backgroundTask.RunWorkerCompleted += new RunWorkerCompletedEventHandler( this.backgroundTask_RunWorkerCompleted); } private void backgroundTask_DoWork(object sender, DoWorkEventArgs e) { SoapClass.apiResponse objFinalResponse ; SoapClass.clientAuth objClientAuth = new SoapClass.clientAuth(); SoapClass.apiAuth objApiAuth = e.Argument as SoapClass.apiAuth; SoapClass.apiService objApiService = new SoapClass.apiService(); objFinalResponse = objApiService.Authenticate(objClientAuth, objApiAuth); e.Result = objFinalResponse; } private void backgroundTask_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Error != null) { MessageBox.Show("Failed!"); } else if (e.Cancelled) { MessageBox.Show("Cancelled!"); } else { SoapClass.apiResponse objFinalResponse = e.Result as SoapClass.apiResponse; MessageBox.Show(objFinalResponse.code); } } private void connectButton_Click(object sender, EventArgs e) { SoapClass.apiAuth objApiAuth = new SoapClass.apiAuth(); objApiAuth.username = this.username.Text; objApiAuth.password = this.password.Text; this.backgroundTask.RunWorkerAsync(objApiAuth); } </code> Tag: Group Policy Tag: 121858

    - Hang when new DirectoryEntry declared I am using the System.DirectoryServices namespace in .net 2003. I have noticed some very strange behaviour related to the DirectoryEntry class. If I debug the following code with a break point on the Console.WriteLine line then there is a lengthy pause before the breakpoint is hit. If I remove the DirectoryEntry line then the breakpoint is hit immediately. static void Main(string[] args) { Console.WriteLine("Test"); DirectoryEntry dirEntry = new DirectoryEntry(); } Also this only happens when I am debugging in Visual Studio. If I run the console app on its own there is no pause. The only thing I could come up with initially was that maybe there was a static constructor that was firing, but this didn't really seem to make sense and looking at the source for the DirectoryEntry class I can't see anything that would account for this pause. Any ideas would be appreciated. Regards Ian Tag: Group Policy Tag: 121857

    - Dowload File Hi, I have problem with downloading a file using WebRequest and HttpWebResponse. Inorder to download this file i need to call to url that tells to prepare the file for download, and then i call to another url that downloads the file. I have a problem with that because: 1. i do not know when the server finished the preparetion. 2.i checked the HttpStatusCode but he doen't changes (myresponse.StatusCode). the problem causes the application to download only a part of the file and that because the server hasn't prepared the file yet. if i give him Thread.Sleep(100000) i do get the full file, but the file can be 100Mb and 10sec won't help. the code is: //Preparing the file todownload... //--------------------------------------------------------------------------------------------------------- HttpWebRequest webRequest3 = WebRequest.Create(d1) as HttpWebRequest; webRequest3.KeepAlive = true; webRequest3.Headers.Add("Keep-Alive", "300"); webRequest3.Headers.Add("Accept","text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"); webRequest3.Headers.Add("Accept-Language", "en-us,en;q=0.5"); webRequest3.Headers.Add("Accept-Encoding", "gzip,deflate"); webRequest3.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7"); webRequest3.CookieContainer = cookies; HttpWebResponse myResponse3 = (HttpWebResponse)webRequest3.GetResponse(); Thread.Sleep(10000); Stream ReceiveStream3 = myResponse3.GetResponseStream(); //----------------------------------------------------------------------------------- //Downloading .... //-------------------------------------------------------------------------------------- Console.WriteLine("Connecting to download link..."); HttpWebRequest webRequest2 = WebRequest.Create(re) as HttpWebRequest; webRequest2.ContentType = "application/x-www-form-urlencoded"; webRequest2.KeepAlive = true; webRequest2.CookieContainer = cookies; HttpWebResponse myResponse2 = (HttpWebResponse)webRequest2.GetResponse(); Stream ReceiveStream2 = myResponse2.GetResponseStream(); Console.WriteLine("Downloading..."); Common.SaveStreamToFile(@"C:\scrapingtest\file.csv", ReceiveStream2); Console.WriteLine("Done Downloading"); Thanks, Rony Tag: Group Policy Tag: 121851

    - MSBuild and VSTS 2005 Forgive me if this is the inappropriate forum to post this, but I found MSBuild.exe in the framework directory so it seems right to me:-) Also forgive me if this duplicates an existing post. I posted this issue the other day, and it seems to have disappeared. (I have way too many posts not be there when I look for them!!!) Finally forgive me that this posting is not as complete as the original. I've made progress so I've had to leave out the error numbers that were part of the original. Now on to the issue: The MSBuild documentation implies that all you have to do is point it at the proj files maintained by the IDE and it will run. It appears to be even nicer than that. Start MSBuild in a folder with a single sln file and it will find and use it. Impressive! HOWEVER, it may or may not run without modification to the projects. I've had to do both of the following: 1) Add references to a library that was lower in the inheritance stack than those needed by the IDE. The projects being compiled didn't refer to this library, but forms were derived from forms that did refer to the library. (I've lost track of how many layers deep the inheritance of the main program window is from Windows.forms.form. It's a bunch.) 2) I had blanks in the names of icons included in the resources and they had to be removed. This has been documented by others elsewhere. I finally came to a show stopper. I'm getting C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets(2071,9): error MSB3188: Assembly BLAHBLAHBLAH must be strong signed in order to be marked as a prerequisite. No place have i marked BLAHBLAHBLAH as a prerequite. I'm not using strong signing precisely because "the directions" which i've actually read of a change discourage it for my target environment. I get this error occasionally in the IDE with various of the libraries in the project being the culprit. To solve the problem there, i just zap all the bin and obj folders and rebuild. (I zapp directories so frequently I wrote a program to do it. It's usually because forms get errors when I attempt to display them.) Zapping directories immediately before calling MSBuild makes no difference. SUGGESTIONS please.

    - Announcement: NLog 1.0 has been released NLog 1.0 has been released.! After 2 years of work, we're proud to announce the availability of NLog 1.0. NLog is a FREE logging library for .NET designed with simplicity and flexibility in mind. See http://www.nlog-project.org for more information about NLog. Source, binary packages and installer packages are available for download from: http://www.nlog-project.org/download.html Tutorial and reference documentation are available at: http://www.nlog-project.org/documentation.html The following people have contributed to NLog by submitting code or bug reports: * Jaroslaw Kowalski <jaak at jkowalski dot net> * Marcin Krupinski <yoszek at gmail dot com> * Inez Korczynski <korczynski at gmail dot com> * Rafal Gwizdala <gwrafal at poczta dot onet dot pl> * Yuri Mamrukov <yvm at att dot net> * Maciej Figatowski <mfigatow at sav dot net> * Perry Rapp <lifelines_3_0_18 at hotmail dot com> * Maarten Claes <m.claes at farcourier dot com> The focus of this relase is future compatibility. Code has been added to ensure that the development of NLog will progress without breaking existing code. The following paragraphs describe changes that made after 1.0 RC1 release. Breaking API changes: * Added NLog.ILayout which Layout implements to allow other layout types (such as CSV-escaped, HTML-colored, XML-escaped, ANSI-colored) to be implemented. * NLog.Layout became sealed. * FileTarget.KeepFileOpen is back to the default of false. we now have <default-target-parameters /> so this default can be easily overriden. * Added NLog.TargetWithLayout, removed Layout and CompiledLayout from NLog.Target * Removed CSVFile target, converted examples to File + CsvLayout * Removed LogEventInfo.Empty and replaced with LogEventInfo.CreateNullEvent() * Changed the default value of FileTarget.OpenFileCacheTimeout to -1 Packaging changes: * Added publisher policy generation and established NLog versioning policy. See http://blog.jkowalski.net/?p=55 for more information about NLog versioning policy. * Build number is synchronized with SVN number. * Added VJSharp and Web item templates. Updated the installer to support VWD Express 2005. * Synchronized Visual Studio solutions to source code directories. Now part of the build process. * New NLog.Benchmark that uses code generation and compilation to create more "clean" environment. Changes to the logging infrastructure: * Added <targets><default-target-parametes /></targets> that specifies default values for all targets in the section * Added Initialize() and Close() to the LayoutRender class * Added optimized CurrentTimeGetter which is way faster than DateTime.Now * Fixed LayoutRenderer.ApplyPadding() null handling * Added infrastructure to create your own logger types inheriting from Logger: LogManager.GetLogger(string name, Type type) LogManager.GetCurrentClassLogger(Type type) LogFactory.GetLogger(string name, Type type) LogFactory.GetCurrentClassLogger(Type type) * Added PopulateLayouts() method to ILayout * Added ${event-context} layout renderer that extracts information from LogEventInfo.Context * Added LogManager<LoggerType> that manages logger instances of LoggerType where LoggerType : Logger * Added support for nested layout renderers. Used in ${file-contents}: ${file-contents:fileName=${basedir}/aaa.txt} * Added support for DEFAULT nested layout parameters. You can now write: ${file-contents:${basedir}/file.txt} ${rot13:URYYB} * Added pluggable layouts (CSV, Log4JXml), LayoutFactory and LayoutAttribute. The syntax is: <target xsi:type="File"> <layout xsi:type="CSVLayout"> <column name="message" layout="${message}"/> <column name="level" layout="${level}"/> </layout> </target> Of course the old syntax is still supported for simple layouts: <target xsi:type="File" layout="${message}"/> * Added ILayoutWithHeaderAndFooter for layouts that support header/footer (such as CSV Layout, more to come) * Enhanced XSD Schema generation by properly generating abstract and layout properties. * Added FilterResult.IgnoreFinal and FilterResult.LogFinala which suppress processing of further rules if the filter matches. * Added NLogConfigurationException which is thrown instead of CLR exceptions when the configuration fails * Simplified XmlLoggingConfiguration by splitting large methods and moving common functionality to PropertyHelper * Added [DefaultParameter] attribute which allows for nameless parameters to layout renderers: ${aspnet-application} ${aspnet-request} ${aspnet-session} ${date} ${environment} ${file-contents} ${gdc} ${mdc} ${process-info} ${special-folder} ${asp-application} ${asp-request} ${asp-session} * Moved the implementation of LogManager to a reusable LogFactory while maintaining its public interface. You can noweasily have a private LogManager for an assembly. New additions: * Added MaxMessageSize (default: 65000) and OnOverflow (default:Split) to the Network target * Implemented headers and footers for the File target. CAUTION NLog automatically writes footers for files that have not been written for 2 days (48 hours). This is done do conserve memory for long-running processes that create lots of log files. * Enabled DatabaseTarget.ConnectionString to include layouts. * Added eventID and categoryID parameters to EventLog targets. * Added ${file-contents} layout renderer which inserts file contents. * Added MailTarget.AddNewLines to insert new lines between header/lines/footer * Added FormControl target that logs to Text property of any Windows.Forms.Control * Added RichTextBox target with row- and word coloring that logs to RichTextBox * Added ${tempdir} and ${specialfolder} * Added ${gc} which can be used to get the GC statistics (very limited) * Added ${processinfo} which can be used to extract the performance information about the current process (possibly others in the future as well) * Added ImpersonatingWrapper which temporarily changes the credentials for the duration of the write. * Added NLog_Init() and NLog_InitLocal() APIs to NLogC Bug fixes: * Fixed File target for Windows 98 * Fixed Network target to work properly with IPV6 * Changed RichTextBox Target to be thread safe. Uses delegate to log to RichTextBox Documentation updates: * Added examples of inheriting from Logger class and wrapping it * Added missing code documentation * Added example ${rot13} layout renderer - that demonstrates how wrapper layout renderers can be written. * Added proper camelCasing to the web build process * Fix for multiple email addresses being passed in To,CC and BCC fields under .NET 2.0 (reported by Pawel Parzychowski) Tag: Group Policy Tag: 121840

Hi Jens
Thanks for the links.
However I was unable to find how to retrieve the
group policy for the OU.
I need the values for the maxPwdAge and lockoutDuration attributes
that I have set for my OU.
I am able to retrieve the values that are set for the domain as a whole,
But not what I have set for my OU and which override the remaining
domain policies.
