    - Gracefully fail to start a service If my service fails to start, I'd like to notify the user and either display an error or direct them to check the event log to see more info. With Win32, you could return a non-0 number to the SCM during startup and a dialog would be displayed (by the SCM) showing the error number and directing the user to check the error log for further information. Is there similar functionality in .NET? I've tried throwing exceptions and calling Environment.Exit([some number]) in OnStart(), but both cause the SCM to display some useless dialog. How are you guys handling this? -Joel Tag: Cdo not working after security updates in windows 2K and XP Tag: 75613

    - newline characters stripped from HTTPWebResponse Hi, I am downloading a .csv file and saving it locally. I am using HTTPWebRequest, getting the Response stream, and copying the stream to a file. It always works fine in the debugger, but most of the time the release version is stripping out many of the carriage returns/line feeds. My code: request = WebRequest.Create(myURL) response = request.GetResponse() Dim responseStream As Stream = response.GetResponseStream() Dim fileStream As New FileStream("myfile.csv", FileMode.Create) Dim r As New BinaryReader(responseStream) Dim w As New BinaryWriter(fileStream) Try Dim b(4095) As Byte Dim iBytesRead As Integer Dim iBytesTotal As Integer iBytesRead = r.Read(b, 0, b.Length) While iBytesRead iBytesTotal += iBytesRead w.Write(b, 0, iBytesRead) iBytesRead = r.Read(b, 0, b.Length) End While Finally w.Flush() fileStream.Close responseStream.Close End Try Any ideas why this might be happening? By the way, I am currently using WebClient.FileDownload, and it works fine, but I would still like to understand what I am doing wrong.

    - Scrollbar Event Hi, I have a windows application that's using the Datagrid to display records. The datasource has the potential of being very large, so I'm only retrieving a certain number of records at a time into a dataset. So, as I scroll down to the bottom of my datagrid, the next page of, say 100 records is appended to the dataset and so on. The code I'm using in the Scroll event is displayed below. For Each c As Control In DataGrid1.Controls If c.GetType Is GetType(VScrollBar) Then Dim scr As VScrollBar = CType(c, VScrollBar) If scr.Maximum < scr.Value + 13 Then mnPage += 1 MapClientsToList() 'Populates the dataset with another page of records. End If End If Next The Problem I'm having is that when I scroll to the bottom, the event is fired, the dataset is populated as desired. However, the event is called again and again in a kind of loop until there is no more data. The scrollbar is apparently being positioned to the bottom every time the data is retrieved, calling my procedure each time. Does anyone have any thoughts on this? Thankyou, Jeff Tag: Cdo not working after security updates in windows 2K and XP Tag: 75607

    - How to load XML string into DataGrid and associate a element attribute to a column? Hi, I have a query return in a XML string. My XML result looks like: <activities> <activity> <subject>Win the Nobel</subject> <scheduledstart date="01/01/2005" time="00:00">2005-01-01T00:00:00-3:00</scheduledstart> </activity> </activities> If a dont have the scheduledstart element, the loading of result into a DataSet works fine, but when I try put the element and associate it with a column I get a error (something like "field scheduledstart not found"). See my code: NameTable nt = new NameTable(); XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt); XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None); XmlTextReader tr = new XmlTextReader(strResultsXml, XmlNodeType.Document, context); DataSet ds = new DataSet(); ds.ReadXml(tr); BoundColumn colAssunto = new BoundColumn(); colAssunto.HeaderText = "Assunto"; colAssunto.DataField = "subject"; BoundColumn colInicio = new BoundColumn(); colInicio.HeaderText = "Inicio"; colInicio.DataField = "scheduledstart"; dgResultado.AutoGenerateColumns = false; dgResultado.Columns.Add(colAssunto); dgResultado.Columns.Add(colInicio); dgResultado.DataSource = ds; if (ds.HasChanges()) dgResultado.DataBind(); How I associate the scheduledstart date and time attributes to two columns or the content of the element to one column?

    - GetValue and ISerialization, object not constructed?? I've got this strange problem in a class that uses ISerializable to serialize a NameValueCollection During deserialization, in the object constructor, after using GetValue to get the NameValueCollection from SerializationInfo, the NameValueCollection is not usable. It throws a NullReferenceException from pretty much any property/method. It is usable after the object is deserialized, but not in the constructor. I've narrowed down the code to a small sample. Can an object not be used during the deserialization constructor? I haven't found any docs that say this shouldn't be allowed Code sample ================Snip============== using System using System.Collections.Specialized using System.IO using System.Runtime.Serialization using System.Runtime.Serialization.Formatters.Binary using System.Runtime.Serialization.Formatters.Soap namespace SerializationTes [Serializable public class SerializeMe : ISerializabl private NameValueCollection values public SerializeMe() values = new NameValueCollection() values.Add("string1", "hi") values.Add("string2", "there") protected SerializeMe(SerializationInfo info, StreamingContext context) values = (NameValueCollection) info.GetValue("values", typeof(NameValueCollection)) PrintMe(); // <-- why can this not access values?? // throws null reference exception inside values.get_Count( static void Main(string[] args // create one, print i SerializeMe serializeme = new SerializeMe() serializeme.PrintMe() // serialize it to fil FileStream file = new FileStream("c:\\test.txt", FileMode.Create) SoapFormatter formatter = new SoapFormatter() formatter.Serialize(file, serializeme) file.Close() serializeme = null // read it back and try to prin file = new FileStream("c:\\test.txt", FileMode.Open) try serializeme = (SerializeMe) formatter.Deserialize(file) serializeme.PrintMe(); // <-- this works, what is different here than print in constructor } catch(Exception e) Console.WriteLine("Failed: " + e) file.Close() public void PrintMe() Console.WriteLine("Items: " + values.Count) foreach(string sKey in values.Keys) Console.WriteLine("Key: " + sKey + ": " + values[sKey]) public void GetObjectData(SerializationInfo info, StreamingContext context) info.AddValue("values", values) Tag: Cdo not working after security updates in windows 2K and XP Tag: 75594

    - The Register directive for the referenced assembly Hello everybody! I am authoring my custom webcontrol and faced a very difficult problem. I have two assemblies: the first one contains some base classes and the second one contains a class which 1) Inherits a class from the first assembly 2) Contains references to the first assembly's class instances. When I drop the control from the second assembly onto a form, it adds references for both assemblies to the project, but it creates only one Register directive (which defines the TagPrefix) in the aspx code. At design time the control is displayed fine, but at run-time it throws an exception. To solve the problem one should manually add the Register directive for the base assembly. Does anybody know what should I do to that the Register directives for both assemblies were created automatically when one drops the control onto a form? Any help is appreciated Thank you in advance!

    - General access denied error adding user to group when impersonating Hi, I'm successfully impersonating an administrative user (using KB306158). I know it is successful because after the impersonation, the WindowsIdentity.GetCurrent().Name returns the admin credentials (before the impersonation it returns the logged-in user's credentials). I'm also testing the user's role (using IsInRole()) and receive True for Administrator. However, when attempting to add a user to the group, I receive a 'UnauthorizedAccessException: General access denied error'. Assuming that I copy-pasted the code from KB306158, so that I have the impersonateValidUser() function: this.Response.Write("<BR>before: " + WindowsIdentity.GetCurrent().Name); // returns the current non-priviliged user if( impersonateValidUser(admin, domain, password) ) { this.Response.Write("<BR>after: " + WindowsIdentity.GetCurrent().Name); // returns the actual admin account WindowsPrincipal principal = new WindowsPrincipal( WindowsIdentity.GetCurrent() ); this.Response.Write("<BR>in role: " + Convert.ToString( principal.IsInRole( WindowsBuiltInRole.Administrator ) ) ); // returns True // ... (code which retrieves existing group and existing user ldap path) // fails 'UnauthorizedAccessException: General access denied error' grp.Properties["member"].Add(userPath); grp.CommitChanges(); } Thanks in advance, Elad.

    - Architecture: Scalability VS Performance This is a design / inheritance qus. I have class Task. This is a base class for some specific tasks Say WorkOrderTask : Task TimeSheetTask : Task Now Task has a function GetDetails() which gets all info about task. This makes a database call. I override this in the derived class. For implementing this in derived class i see following 2 approaches. Approach 1. WorkOrderTask .GetDetails() { Calls base.GetDetails(); to get base details, populates in the object Gets details specific to WorkOrderTask, populates in the object returns; } Approach 2. WorkOrderTask .GetDetails() { Get details specific to WorkOrderTask as well as the base class details, populates in the object returns; } The problem with Approach 1 I have to make 2 database calls. Approach 2 If theres some change in base class I need to take care of these in all the derived classes as well. Whereas, Approach 1 is advantageous here as by modifying only the Task.GetDetails funciton ( this is the base class ) function i have all the values and i do not need to touch the derived classes. Was thinking this might be a very common problem, so perhaps many of might be able to guide me on the approach i must take here. Perhaps anything other then the two i have talked about.

    - Visual Studio 2003 compatibility with original Visual Studio .Net My old laptop has the original version of Visual Studio .Net running on Windows 2000. My new laptop has Visual Studio .Net 2003 running on Windows XP. I imported an existing Web project to the new laptop, made some modifications, rebuilt the project, and pushed the changes, including the DLL and PDB files, to our "test and QA" server. The application blew up on the first screen; the error was something like "unable to find the query string collection object". I copied the changed .aspx and .aspx.vb files back to the old laptop, rebuilt the project, and again pushed all changes, including the DLL and PDB files, to the "test and QA" server. This time, no problem. What do I have to do so that our servers, including our client's production servers, can run applications developed with VS .Net 2003? Much obliged.

We use the following code to do this if (PerformanceCounterCategory.Exists(categoryName) PerformanceCounterCategory.Delete(categoryName) CounterCreationData ccd = new CounterCreationData(counterName, counterHelp, PerformanceCounterType.RateOfCountsPerSecond32) CounterCreationDataCollection ccdc = new CounterCreationDataCollection() ccdc.Add(ccd) PerformanceCounterCategory perfCategory = PerformanceCounterCategory.Create(categoryName, categoryHelp, ccdc) OurLibrary.Error.AssertThrow(perfCategory.CounterExists(counterName), String.Format("Expected \"{0}\" counter to exist.", counterName)) PerformanceCounter counter = new PerformanceCounter(categoryName, counterName, false) We get a "Category does not exist" InvalidOperationException when we assert that the counter exists. perfCategory != null at this time. The PerformanceCounterCategory.Create does NOT throw. We have tried many permutations of calls to try to get this to work, but it always throws. The odd thing is that the category and counter are actually created in the perfmon utility. We can see them from .net too, but not in the process that created them. We have tried this same code on Windows 2000 boxes and it works correctly. What is the problem with the Windows 2003 and XP operating systems that cause this to fail? We have searched the newsgroups and have not seen any explanations and very few instances of this problem. Are we the only ones using the .net performance counters Thanks Frank Tag: Cdo not working after security updates in windows 2K and XP Tag: 75487

    - Good sockets tutorial needed Can anyone give me some links to tutorials on using sockets with .NET? Here's my scenario: I'm writing a service in .NET. I want to be able to create clients which can talk to the service to both get status information from it and also make configuration changes. I figure a simple TCP connection would be the easiest way to facilitate communication. I'm no sockets guru in the first place or I'd try to muddle through it on my own (which of course I may have to). Any pointers would be appreciated, and any suggestions on a better way to set up program-program communication across different machines would be welcomed.

    - HOWTO: Add help file to .Net IDE Gentlemen I've developed a library that a good number of programmers are using. I've also now created a Help file that explains this library Where could I find a white paper or article which would explain HOWTO add a third-party help such as mine so that it appears as a "Filtered by:" category within .Net Index, so that my programmers can reference this help right within .Net?

    - Runs Slow The First Time I have an application that uses data access that runs slow the first time. My first page reads data from an ODBC source and the second page hits a MSDE database. After each page opens the first time, they run just fine. What should I do? I have all my code in ASPX pages right now, but I would like to break it up in some code behind. Also, is this the advantage in pre-compiling data access classes (like in a dll or is there an easier way)? Help appreciated. Thanks.

    - passing values between web forms usign session variables any comments on this? I always use session variables to pass values among web forms. That is if I get a username, password in a Login form, then I pass these to the subsequent Search form as session variables. The search form needs to know who login to display the appropriate data.........is this the most efficient way of doing this?

    - Mutex Differences VB.NET & C# Hi, I've got the following C# code that works perfectly to prevent a 2nd instance of my C# app: bool bAppNotRunning = false; Mutex MutApp = new Mutex(true, "MyC#AppMutex", out bAppNotRunning) if(bAppNotRunning == true) { Run the app and do work... MutApp.ReleaseMutex(); } I did the same thing in another app that's in VB. NET to prevent a 2nd instace of it: Dim bAppNotRunning As Boolean bAppNotRunning = False MutApp = New Mutex(True, "MyVBAppMutex", bAppNotRunning) If(bApNotRunning = True) Then Run the app and do work... MutApp.ReleaseMutex() End If Why doesn't the VB version work? bAppNotRunning comes back True from the Mutex constructor even when another instance of the app is already running?! What gives? Any ideas would be appreciated. TIA, -- John C.

    - RSACryptoServiceProvider constructor very slow under Win XP I have a .NET app that uses the RSACryptoServiceProvider class to perform a key exchange with a server. During testing we've found that on some Windows XP machines, the call to the constructor for this class can take 15 or more seconds! On our Win 2K and Win 98 test machines it always takes less than 3 seconds. The problem's very easy to reproduce -- just create a console app with one line of code in it: RSACryptoServiceProvider p = new RSACryptoServiceProvider(); One most machines, this should run fairly quickly. On the afflicted machined, it's very slow. I know that the key generation goes on during the constructor, but 15 seconds...?!?! Also, as I said, this only affects SOME XP machines -- we have others that work just as the Win 2K boxes. To compare the XP machines that work fine to those that don't, we compared the advapi32.dll versions/dates, but they were identical. Has anyone else seen this issue or have any idea why XP would be so slow in generating running this constructor?

    - Class Modifiers via Reflection Is there a way to determine the access modifiers of a class type in an assembly via reflection? I see that I can determine if the class is public or non-public, but I would like to be able to further sub-divide the non-public modifiers (assembly, family, familyAndAssembly, familyOrAssembly, private). Is this possible with the .NET 1.1 Reflection API? And just to clarify, I see I can get this info for nested classes, but I would like it for non-nested classes too. Thanks for any suggestions or pointers on this. Kevin Tag: Cdo not working after security updates in windows 2K and XP Tag: 75464
