    - XmlSerialization attributes: difference between [XmlElement(...)] and [XmlElementAttribute(...)] While familiarizing myself with XML Serialization and controlling serialization using attributes, I've become confused whether there is a different between the use of "XmlElement" or "XmlElementAttribute" in actually writing the attribute in a class declaration, and in general for any serialization attribute. For example, consider the following class: public class Test { public: // public, parameterless constructor req'd for serialization Test(void) {} public: [XmlElement("Member1")] int m_Member1; [XmlElementAttribute("Member2")] int m_Member2; } Even MSDN doesn't seem quite clear on which to use. From the code I've seen, it sounds like XmlElementAttribute is the object in the .NET framework that handles this, but I am to use "XmlElement" while actualing writing the attribute. In contrast, I have seen other code that appends the "Attribute" part of the object name. What is the difference, and which is correct Anjo Tag: .NET Base Class Library NTAccount.Translate for '<Domain>\Administrators' group account fails .NET Development

    - SqlDependency timeout problem I'm on XP, SqlSever 2005, .NETfx 3. I'm using SqlDependency to get notifications of changes to my data store. My intent is that when I set up a SqlDependency object, that it will be in effect "forever". However, I find that after 2 minutes or so, changes will not trigger notifications anymore. I initialize the dependency once per app domain thusly: SqlDependency .Start(_connectionString); this ._dependencyConnection = new SqlConnection (_connectionString + "Connection Timeout=" + Int32 .MaxValue.ToString()); _dependencyConnection.Open(); I set up a new notification (once at startup, and after each notification) like this: SqlCommand command = new SqlCommand ( "SELECT Revision FROM dbo.ConfigData where [Key] = '" + _ourKey + "'" , _dependencyConnection); SqlDependency dependency = new SqlDependency (command, null , Int32 .MaxValue); dependency.OnChange += new OnChangeEventHandler ( this .OnChange); SqlDataReader reader = command.ExecuteReader(); reader.Close(); This will fire notifcation for a change that happens within 2 minutes or so. After that, nothing. What am I missing here Thanks Riley Tag: .NET Base Class Library NTAccount.Translate for '<Domain>\Administrators' group account fails .NET Development

    - define a new querydef in an access db using asp.net My scenario is this: I have inherited a large access database, critical to a website. I need to do some work on the site which requires that I modify a number of tables and create a few ne querydef so support the work. The obvious soluition is to ftp the db locally, modify the file and upload it. But If possible I do not want to do this. I don't want to lose data and I don't want to take the db offline. So what I would like to do is create an aspx page which I can use to do operations like creae new querydefs. How can I connect to an access db to do these kind of operations As far as I can tell, the regular OleDbConn does not allow me to do these operations - rather I need to use the access object model. I suspect there must be some utility out there on the internet to do this kind of thing (a bit like phpmyadmin).

    - "Deserializing" XmlNode.OuterXml to object, then back to XmlNode questions I am not able to reproduce the problem, both XPath and schema validation work normally for me, even when the xmlns attribute has been removed. The namespace of an element node in the DOM model is determined by its namespaceURI property and not by any namespace declaration attributes. Here is my sample code: Code Block XmlDocument doc1 = new XmlDocument (); doc1.LoadXml( "<root xmlns=\"http://example.com/ns1\"><bar/></root>" ); XmlDocument doc2 = new XmlDocument (); doc2.LoadXml( "<foo xmlns=\"http://example.com/ns1\"></foo>" ); doc2.DocumentElement.RemoveAttribute( "xmlns" , "http://www.w3.org/2000/xmlns/" ); doc1.DocumentElement.ReplaceChild(doc1.ImportNode(doc2.DocumentElement, true ), doc1.DocumentElement.FirstChild); doc1.Save( Console .Out); Console .WriteLine(); XmlNamespaceManager mgr = new XmlNamespaceManager (doc1.NameTable); mgr.AddNamespace( "pf" , "http://example.com/ns1" ); Console .WriteLine( "Number of nodes: {0}." , doc1.SelectNodes( "//pf:foo" , mgr).Count); XmlSchemaSet schemaSet = new XmlSchemaSet (); schemaSet.Add( null , @"..\..\XMLSchema1.xsd" ); doc1.Schemas = schemaSet; doc1.Validate( delegate ( object sender, ValidationEventArgs vargs) { Console .WriteLine( "{0}: {1}" , vargs.Severity, vargs.Message); }); SelectNodes finds one node and schema validation outputs a validation error. I will post the schema sample in a follow up post as the forum software otherwise makes a mess of posted code samples.

    - ILMerge: Problem with references Hi, I'm trying to use ILMerge to create components for the Umbraco web framework. I thought it would be nice is I only had to distribute one dll with my component. The setup I'm using is ( a bit simplified): MyComponent.csproj (Visual Studio web project) .... --References ----umbraco.dll (local reference, Copy Local == false) ----SomeComponent.dll (local reference, Copy Local == true) ----System.Web (GAC reference) .... The reason that I have Copy Local == false on the umbraco.dll is that this dll is part of the solution that my component must be deployed to. The SomeComponent.dll is a component used by my UserControls in my project and this is the dll I would like to merge with MyComponent.dll However if I execute: "ilmerge.exe /out:MyComponent.dll SomeComponent.dll" i get an error message saying: "Unresolved assembly reference not allowed: umbraco" I can however not just include the umbraco.dll since this would result in the classes within the umbraco.dll being defined twice when I deploy the MyComponent.dll in the umbraco web application. So my question is there anyway to avoid this error message or is ILMerge an all or nothing solution Regards, Rasmus Oudal Edberg Tag: .NET Base Class Library NTAccount.Translate for '<Domain>\Administrators' group account fails .NET Development

    - Strange: calling EndInvoke from an AsyncCallback - why UnhandledException I'm sorry, I've reread this several times and I don't fully understand what you're trying to say. Alois wrote: The problem you encounter here is that the CLR will rethrow the exception inside the callback when you call EndInvoke. Yes, I'm aware of that. I expect EndInvoke to throw to signal the fact that the asynchronous method threw, but I expect it to throw Application.ThreadException, not AppDomain.UnhandledException, since it's running on the UI thread. Alois wrote: But it does only check if you do call EndInvoke on the same thread the callback executes. I'm not sure what check you're referring to. Alois wrote: Since you call EndInvoke ulitmately from an arbitrary thread... Not from an arbirary thread, from the thread that controls the form's underlying window handle, which is the UI thread, same as in cases 1-3. Alois wrote: ...the CLR thinks your callback did not handle the exception... Well, it deliberately did not handle the exception because I want it to throw ThreadException. I'm not sure what the point you're making here is. Even if I handle the exception in the callback and rethrow it, or throw a completely new exception, it still results in an UnhandledException. Alois wrote: ...and wil rethrow the exception when your callback is left. But the callback never completes -- it's the actual EndInvoke that terminates the app. Have I misunderstood what you were trying to say It's not that an exception is ultimately being thrown by EndInvoke and caught by the global handlers that bothers me -- I'm expecting that. What I don't understand is why the exception is an UnhandledException (that kills the app) and not just a ThreadException (that does not). The original exception was not a fatal error, yet it's impossible to prevent the app from dying without handling the exception inside the asynchronous callback. If you have hundreds of asynchronous callbacks in your application, you'd have to replicate your application_ThreadException code in every one of those. I can certainly do that, but I'd like to understand why I need to first. It makes a mockery of a global exception handler, and in my case could provide other problems, since my async methods are scattered across a dozen or so UI components.

    - C# - MSMQ - HTTP Issues I know this is not really a 100% C# question, however I'm trying to utilize MSMQ via C# over HTTP... I'm finding that I cannot create or check for the existance of Queues utilizing the HTTP channel whether they are private or public. Example code: string url = "FormatName IRECT=HTTP://myserver/ MSMQ/myqueue"; MessageQueue.Exists(url); MessageQueue.Create(url); Note: the annoying emoticon above shows up because its really a : D w/ no space For both of those methods I get errors eluding to - cannot create / check existance with that path syntax. I've also seen this example - changing the : to an = after FormatName, that seems worse off though just plain saying its an invalid syntax altogether. string url = "FormatName=DIRECT=HTTP://myserver/ MSMQ/myqueue"; As far as I've read, you can create / check the existance of Queues via HTTP, however I cannot get any example to work... all of the documentation I've seen only uses the OS direct path to do so.... Anyone have any ideas I can however retreive messages from the Qeueue via HTTP w/ that url syntax, but... w/ the architecture I'm working on I'd like to check for its existance first from the client. At this point I'm considering doing so with a webservice call prior to connecting to the Queue.

    - .NET QueryBuilder and IN(Transact-SQL) function I wrote my first post on a hurry. You can do that using command parameters but you must do it on the right way: private void button1_Click( object sender, System. EventArgs e) { SqlConnection conn = new SqlConnection ( "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True" ); SqlCommand cmd = new SqlCommand ( "SELECT * From Person.Contact WHERE ContactID IN (@FirstID, @SecondID)" , conn); cmd.Parameters.Add( "@FirstID" , SqlDbType .Int, 4).Value = 1; cmd.Parameters.Add( "@SecondID" , SqlDbType .Int, 4).Value = 2; DataTable dt = new DataTable ( "Contacts" ); SqlDataAdapter da = new SqlDataAdapter (cmd); da.Fill(dt); //this is valid and you will have two rows in the table } private void button2_Click( object sender, System. EventArgs e) { SqlConnection conn = new SqlConnection ( "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True" ); SqlCommand cmd = new SqlCommand ( "SELECT * From Person.Contact WHERE ContactID IN (@IDs)" , conn); cmd.Parameters.Add( "@IDs" , SqlDbType .VarChar, 20).Value = "1, 2" ; //this is invalid because you will get "IN ('1, 2')" instead of "IN (1, 2)" DataTable dt = new DataTable ( "Contacts" ); SqlDataAdapter da = new SqlDataAdapter (cmd); da.Fill(dt); //this fails here with conversion error } So if you need to create dinamic query where you don't know the namber of id's in IN clause then you will have a List<int> as previous post described and you will dinamically create the command text on IN clause part and you will again with generic procedure add all params. It will be something like this: private void button 3 _Click( object sender, System. EventArgs e) { List < int > ids = new List < int >(); ids.Add(1); ids.Add(2); ids.Add(5); SqlConnection conn = new SqlConnection ( "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True" ); SqlCommand cmd = new SqlCommand ( "" , conn); string commandText = "SELECT * From Person.Contact" ; if (ids.Count != 0) { commandText += " WHERE ContactID IN (" ; foreach ( int id in ids) { commandText += "@ID" + id + ", " ; } commandText = commandText.Substring(0, commandText.Length - 2) + ")" ; foreach ( int id in ids) { cmd.Parameters.Add( "@ID" + id, SqlDbType .Int, 4).Value = id; } } cmd.CommandText = commandText; DataTable dt = new DataTable ( "Contacts" ); SqlDataAdapter da = new SqlDataAdapter (cmd); da.Fill(dt); } You can change the source to use StringBuilder for creating the commandText and also 'for' loop will be better if you want to handle the last ',' comma better.

    - Talking between two applications Hi. I am developing a client-server home automation application on which the RS232 serial port must be opened in order for a client application (such as a timer, lighting control, etc.) to talk to a Home Automation host application. It goes like this: RS232 (port) <-{> PowerLine Modem Communication (internal class) <-> Host (form application; internal class) <-> Insteon (public class) <}-> Client Applications The "{}" represents an entire assembly that is executable (calls out the Host form). The "s" in "Client Applications" can be visualized as multiple blocks connected to a single, big block; thus, if you visualize it in a diagram, you'll know what I mean, as multiple clients that talk (interface) with a central host (server) application. I can do that through .net Sockets (TCP/IP), but I have a class that use enums. Plus, the client and server applications will all be in one machine. With my explainations out of the way, plus I've coded everything like for setting up an RS232 communication for PowerLine Modem communication through Insteon network (refer to the link about Insteon), I have a couple of questions: How do I make my client application (timer/evenr or lighting control, for example) talk to the server application for gathering variables set by the server application How do I gather a state of a running application (example: if a client application requires a server application to run) For question 1, what I mean is if a server application's isConnected boolean variable is set to true (like when a server application instantiated a new PLM class, tells the PLM class to open the port, etc.) or not, whether an application received an acknologement from an Insteon PowerLine Modem (isPowerLineModemAvailable), etc. This is something that client applications must be able to communicate with the shared, single running instance of a server application.

    - Issue with SqlCommand and Parameters.Add You need to declare your sql statement before the loop and also add the parameters before the loop. In the loop you will just set the value for every parameter: SqlCommand cmd = new SqlCommand("UPDATE myTableName SET FirstName = @FirstName, SecondName = @SecondName WHERE ID = @ID", connection); cmd.Parameters.Add("@FirstName", SqlDbType.VarChar, 20); cmd.Parameters.Add("@SecondName", SqlDbType.VarChar, 30); cmd.Parameters.Add("@ID", SqlDbType.Int, 4); //first and only FOR loop, don't need two loops for (int i = 0; i < dTable.Rows.Count; i++) { ....... cmd.Parameters["@FirstName"].Value = dTable.Rows[ i]["FirstName"]; cmd.Parameters["@SecondName"].Value = dTable.Rows[ i]["SecondName"]; cmd.Parameters["@ID"].Value = dTable.Rows[ i]["ID"]; cmd.ExecuteNonQuery(); ..... } cmd.Dispose(); connection.Close(); If you want to read column names dinamically and their size then you can do that out of the loop, why inside the loop. In the loop all that you do is read values, update parameters values and execute command. Disposing and closing connection should be done outside of the loop.

Try somthing like pr.InsertPayee( Convert .ToInt32(txtPRNum.Text), Convert .ToString(drpStaffID.SelectedIndex), txtDate.Text, txtWpm.Text, drpPurchaseAuth.SelectedValue.ToString(), txtAmount.Text, txtDescription.Text, drpTaxable.SelectedValue.ToString(), drpOMWBE.SelectedValue.ToString(), txtAttn.Text, txtPurpose.Text, chkActual.Checked, chkEstimate.Checked, drpPayee.SelectedValue.ToString() ); Thats probably not exactly right but it should point you in the right direction.

Hi!
Can anyone please explain me why following code gives an SecurityException "System.Security.SecurityException: The name provided is not a properly formed account name."

-- code start --

System.Security.Principal.NTAccount ntAccount = new System.Security.Principal.NTAccount(@"<domain>\Administrators");
System.Security.Principal.SecurityIdentifier sid = (System.Security.Principal.SecurityIdentifier)ntAccount.Translate(typeof(System.Security.Principal.SecurityIdentifier));

-- code end --

where "<domain>" in "<domain>\Administrators" is your Active Directory Domain.

Note:
<domain>\Administrators is a built-In group. It is visible trough 'Find' dialog in Active Directory Users and Computers Snap-In.
