    - XmlSerialization attributes: difference between [XmlElement(...)] and [XmlElementAttribute(...)] Hi mate, This is nothing to worry about. Attributes in .NET all follow a naming convention where attribute classes are appended with the word Attribute. So the actual name of the class is XmlElementAttribute, also the SerializableAttribute class, and so on. Basically all attribute class names end in Attribute and it's so common that .NET provides you with a shortcut that allows you to leave off the Attribute when you use it. So XmlElement and XmlElementAttribute are exactly the same class. Your best using the shortcut (without Attribute) when you use the attribute but if you create your own custom attribute then name it with the Attribute suffix i.e. MyCustomFeatureAttribute. Its also a bit confusing because XML uses the term attribute so you end up with an XmlAttributeAttribute class. Thats why it's best to use the shortcut.

    - Error generating classes using XSD.exe Hi, The schema must be digitally signed. The errors that are being reported are to do with XML digital signatures (DSIG) elements. You wouldn't want to create code for these. Maybe if you use the /element switch of the XSD to pick out different elements of the schema. Rather than generate the classes from the schema in one large hit, pull out elements and build your classes one by one. Tag: .NET Base Class Library unbuffered stream? .NET Development

    - SqlDependency timeout problem http://msdn2.microsoft.com/en-us/library/ms379594(VS.80).aspx On the return, you can check to see if it’s a timeout on the notification. static void MyOnChanged(object caller, SqlNotificationEventArgs e) { Console.WriteLine("result has changed"); Console.WriteLine("Source " + e.Source); Console.WriteLine("Type " + e.Type); Console.WriteLine("Info " + e.Info); } If the source = "timeout" you know it's a timeout and delegate out another dependency statement.

    - define a new querydef in an access db using asp.net Not sure if it will work for you, but you could use ALTER TABLE... and CREATE TABLE ... DDL statements to modify columns and tables in Access database, and you could execute those statements just as any regular SQL statements using OleDbCommand class (using ExecuteNonQuery method). If database located remotely, then you would need to create Web service that will execute your DDL statements and call Web service from some sort of client application Tag: .NET Base Class Library unbuffered stream? .NET Development

    - "Deserializing" XmlNode.OuterXml to object, then back to XmlNode questions I am not sure I understand what the problem is. If you have a namespace declaration attribute on an element node then you can remove that, that might fix the problem with duplicated namespace declarations once you insert that element elsewhere. Here is a C# example: 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); Result is http://example.com/ns1 "> <foo /> </root> Tag: .NET Base Class Library unbuffered stream? .NET Development

    - ILMerge: Problem with references Hi Rasmus, ILMerge needs to know where all of the referenced assemblies are located (just like the compiler). It looks by default in the directory containing the input directories and the GAC. If you would like to specify other directories, then use the /lib option to ILMerge to specify those locations. So in your example, you could use “/lib:\dddd\” where “dddd” is the path to the directory in which umbraco.dll is located. Please get in touch with the author of ILMerge directly if you need further help. (“mbarnett symbol_that_is_an_a_surrounded_by_a_circle microsoft dot com”) Hope this helps! Thanks!

    - How to execute an ASP.net web service over SSL for consuming in a windows client application? As for as security is concerned, just be sure to realize that SSL only secures the transport of information between the client and webservice. That being said, encrypting the traffic over SSL is a Good Idea. There are a couple ways to accomplish this. From the perspective of a developer, you can get the SSL certificate installed in IIS and change the Urls of the clients to point to the new secure url ( https://olduser/service.asmx ). Be aware that if the domain name of the certificate does not match the url the client uses to connect (or if you let the certificate expire), the clients will start throwing exceptions. This makes it advisable to avoid using an IP address as the endpoint for your SSL webservices. In some environments, that might not be possible, another alternative which I have used in the past, is to have the Network Department to purchase SSL appliances. If your webservice consumers are grouped in the same physical location (such as a warehouse), you can install an appliance on each end of the WAN link. This gets you the same thing as above, but you dont have to make development changes, and the cpu overhead of processing SSL is offloaded to the appliance. Pushing webservice traffic over SSL is really a "first step" to security. Tag: .NET Base Class Library unbuffered stream? .NET Development

    - COM interoperability- SAFEARRAY usage You are treating AddressList as though it is a array of structures. It isn't, it's an array of IAddress pointers. You'll have to call the property getter of the IAddress interface pointer to obtain the value of the PinCode property. Technically, you should call QueryInterface to obtain the IAddress interface pointer. Tag: .NET Base Class Library unbuffered stream? .NET Development

    - Strange: calling EndInvoke from an AsyncCallback - why UnhandledException As far as I know the callback is executed in the thread pool thread that the invoked function was executed. This is not the UI thread where you receive the callback. The other examples 1,2 execute synchronously on the same thread. 3 will delay the exception throwing and "marhsal" the exception to the EndInvoke call into your thread. 4 will definitely be executed from another thread for performance reasons since the call is asynchronous there is no reason to execute the callback (again) in another thread. The CLR simply reuses the thread for the callback where you get the exception then. I think 5 should also terminate your application but have not tried it yet. Perhaps you have to wait a little until the thread starts running. ... Yours, Alois Kraus Tag: .NET Base Class Library unbuffered stream? .NET Development

    - 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. Any help is much appreciated. - Sean Tag: .NET Base Class Library unbuffered stream? .NET Development

    - Enterprise Library for .NET Framework 3.0 Hi Mike, Enterprise Library 3.0 has released the third CTP in february 2007. The final release is not available yet (it should be by the end of march/april... you read more about it in the tom hollander's blog ). The Core of Entlib V3 (App Blocks + config tool + VS Integration) runs over fx 2.0. You need to targte the fx 3.0 if you want to use the new Application Block Software Factory which is a Guidance Package to build your own blocks.

    - C#: characters found after end of sql statement As far as I know this works only with System.Data.SqlClient.SqlCommand objects. You could change the statement to something like SELECT Table1.*, Table2.* FROM Table1, Table2 but you end up with a cross join - which means that Fill would create only one table in the dataset. With the SqlClient provider the code might look like this: Visual Basic Dim connectionString As String = "Data Source=.\SQLEXPRESS; Integrated Security=SSPI; Initial Catalog=NorthwindCS;" Dim ds As New DataSet( "Northwind" ) Using adapter As New SqlDataAdapter( "SELECT * FROM Products; SELECT * FROM Categories" , connectionString) adapter.TableMappings.Add( "Table" , "Products" ) adapter.TableMappings.Add( "Table1" , "Categories" ) adapter.Fill(ds) End Using Notice the use of TableMappings . Without adding them the Dataset would contain two tables with names like Table and Table1. Tag: .NET Base Class Library unbuffered stream? .NET Development

    - Add XmlAttribute to simple type property? The only way to do that is to declare the ANumber property as object, and to avoid the breaking changes you can do the following: You define two different properties exposing the same member (aNumber) one for used by XmlSerializer, typed as "object" to enable the xsi:type=".." attribute generation, and other typed as int for usability, marked with [XmlIgnore] to avoid the duplicate data in output. public class Test { private int aNumber = 10; [XmlIgnore] public int ANumber { get { return aNumber; } set { aNumber = value ; } } [XmlElement( "ANumber" )] public object XmlANumber { get { return aNumber; } set { aNumber = ( int ) value ; } } } Thanks, elena Tag: .NET Base Class Library unbuffered stream? .NET Development

Is there a StreamReader-like class that will let me read lines of text from a file without buffering I ask because I need to be know the position in the file of the line being read, and since StreamReader buffers data, reading the BaseStream.Position property doesn't report the right offset into the file.

I know I could derive my own class and get it all to work, but if there's something that already exists, I'd rather use that than write and debug my own. If there isn't, then is there some reason for it's exclusion

Re: .NET Base Class Library unbuffered stream?

nobugz

Nope. StreamReader needs a buffer to be able to supply up to 4 bytes of a UTF8 character to the decoder. The buffer position, bytePos, is a private member. You'll need to read the file with FileStream, find the line endings and convert the bytes in between yourself. I assume you've already got something like that.

Re: .NET Base Class Library unbuffered stream?

The Microsoft.Visual.Basic.FileIO FileSystem class would probably do what you want, but it is recommended that it not be used.
