    - SqlTransaction and SqlConnection state after worker thread aborted You are right the problem is actually related to the duration of the transaction and the try/catch block Microsoft says long operation use stored procedures and users says a Using statement will help with the rollback instead of the try/catch. Read the user comments and use the link there are more comments. http://msdn2.microsoft.com/en-us/library/2k2hy99x(VS.80).aspx Tag: .NET Framework Data Access and Storage Problem connecting to sql server express edition .NET Development

    - RSA : Encrypt with private key and decrypt with public key The RSA has the particularity to be "reversable" : you can encrypt with public and decrypt with private, or encrypt with private and decrypt with public. I want to distribute datas that people can only decrypt, as a licence file for example. I create and encrypt a licence with my private key. I distribute the encrypted licence and the public key, so people can read the licence, but noone can generate a licence, except me. Actually, this works really fine with OpenSSL. Now, i want to do the same under .NET. Using the signature is not a way, because i can just verify datas, not decrypt them.

    - Culture and DatePattern Hi, I need to format a string using the month and year codes. But is has to be culture aware. Unfortunately the default YearMonthPattern of DateTimeFormatInfo doesn't do the trick because it displays the months in full text. So I tried to provide a custom pattern, but then it isn't culture aware anymore. Dim d As New Globalization.DateTimeFormatInfo d.DateSeparator = "/" d.YearMonthPattern = "MM/yy" Console.WriteLine(dDate.ToString(d.YearMonthPattern, New Globalization.CultureInfo("en-US"))) Console.WriteLine(dDate.ToString(d.YearMonthPattern, New Globalization.CultureInfo("fr-BE"))) Does anybody have an idea how to solve this Thanks, Jan Tag: .NET Framework Data Access and Storage Problem connecting to sql server express edition .NET Development

    - How to Add/Insert Nodes in XML? Use an XPath expression alike DocumentElement/MyValues[Occupation = 'Doctor'] e.g. with C# you can delete as follows: Code Snippet XmlDocument xmlDocument = new XmlDocument (); xmlDocument.Load( @"file.xml" ); XmlNodeList valuesToRemove = xmlDocument.SelectNodes( @"DocumentElement/MyValues[Occupation = 'Doctor']" ); for ( int i = valuesToRemove.Count - 1; i >= 0; i--) { valuesToRemove[i].ParentNode.RemoveChild(valuesToRemove[i]); } xmlDocument.Save( "file.xml" ); Tag: .NET Framework Data Access and Storage Problem connecting to sql server express edition .NET Development

    - TypeDescriptor.GetProperties () : Interface Issue Of course the metadata knows about interface inheritance. For example, run the following code: Code Snippet bool doesInherit = typeof (IFoo).IsAssignableFrom(typeof (IBar)); doesInherit is true. (And btw, your IsSubclassOf test is backwards. You are testing if IFoo is a subclass of IBar, but you want to test the other way around. It still comes out false though, because IsSubclassOf only deals with classes. IsAssignableFrom also deals with interfaces.) However, I did find an explanation for the behavior of GetProperties. From the ECMA CLI specification : 8.10 Member inheritance Only object types can inherit implementations, hence only object types can inherit members (see § 8.9.8 ). While interface types can be derived from other interface types, they only “inherit” the requirement to implement method contracts, never fields or method implementations . So IBar inherits the requirement to implement the Foo property, but not the Foo property itself. Still seems a bit shady to me, but its all there in black and white.

    - System.Runtime.Remoting.RemotingException: Cannot load type ... Hi I am trying to call a Window Service written in 1.1, through 2.0 code, using remoting, and serviceController class. But i am getting the error, Error System.Runtime.Remoting.RemotingException: Cannot load type BServiceReporter... Source "mscorlib" when I try to call the method GetBWorkerStatusList . oReporter = ( BServiceReporter ) Activator .GetObject( typeof ( BServiceReporter ), sTcpAddr); m_xBatchWorkersStatusList = oReporter.GetBWorkerStatusList(); The lines work, if the ServiceController class uses, WindowService, written in framework 2.0 (But we have to use older windows service; business requirements) I also looked at the following article, which i suspected, and installed the patch, but i think the problem is different http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=300062&SiteID=1 Any help in this, will be highly appreciated thanks in advance Jan Tag: .NET Framework Data Access and Storage Problem connecting to sql server express edition .NET Development

    - Eventid missing in Framework 2.0 I don't quite know how to explain the disparent values. One thing I will point out though is that you'll ultimately be getting back an int so you should truncate the InstanceID (which is a long) to an int before doing the binary operation. Maybe this will resolve your issue. Michael Taylor - 2/17/07 http://p3net.mvps.org Tag: .NET Framework Data Access and Storage Problem connecting to sql server express edition .NET Development

Why don't you pare it down, removing controls one after another, until you've found the minimum app that you think that leaks, then post again.

    - thread.abort causes "error 2" Hi, I have a application that ataches to an Excel file (using jet 4) and fills a dataset in a background thread. This background thread uses calls a specific dll to handle the connection to the Excel file. If the user clicks 'Cancel' from the main form then the main thread calls thread.abort followed by thread.join. However, just after thread.abort is called a messagebox pops up saying "Error 2" - no other text or title is displayed in the messagebox. I have no idea what is causing this error - i have tried catching the threadabortexception but the messagebox pops up before this exception is caught. I am really stumped by this...any help would be really appreciated. Tag: .NET Framework Data Access and Storage Problem connecting to sql server express edition .NET Development

    - Access memory error after unmanaged interop in Vista. In this case, since unmanaged function GetStringFromUnmanaged is returning a pointer to a block of memory, the piece of memory by convention is now owned by the CLR. After CLR makes a copy of that memory, it decides that it no longer needs the memory any more (since it already has a copy) and frees it by CoTaskMemoryFree (or SysFreeString in the case of BSTR. SysFreeString basically does the same thing as CoTaskMemoryFree, except that it needs to do some pointer adjustment for the BSTR pointer). -- Yi Zhang, Microsoft This posting is provided "AS IS" with no warranties, and confers no rights.

    - Web Service noob needs some help Ok, let's go step by step. The problem you're facing here is that you've not installed ASP.NET, that's why you get this error and that's why you don't see the templates in Visual Studio. I'd suggest you to re-run the Visual Studio installation so you can add features and then look for the ASP.NET item (or something with Web related - I don't really remember how it is shown in the installation). Then, you have to go through Programs -> Visual Studio 2005 -> Visual Studio Tools -> Visual Studio 2005 Command Prompt. This will open a cmd, there you'll register ASP.NET in IIS running this command: > aspnet_regiis -i Then, try to open the ASMX again in IE, and try to see whether in VS you have the templates to create web sites. Please try this, and then we can continue with the remaing issues. Regards, Rodrigo Tag: .NET Framework Data Access and Storage Problem connecting to sql server express edition .NET Development

    - How do I serialize a Bitmap class? Thanks, Mr. Indian Ocean. I understand that the Bitmap.Save can help to serialize the image data to a byte stream. However, I would like to stick with a Bitmap object, i.e. the serialized xml should reside in <Bitmap> element and with corresponding Bitmap properties element under it. I did tried to create my own serializer inherited from XmlSerializer, however, the overrided Serialize method does not get called anyway. When I look at it in Reflector, I found out that the Serialize method first call the abstrac API, CreateWriter, of the XmlSerializer base class. This API suppose to return a XmlSerializationWriter object which is documented as .Net Framework internal class and not to be used by us. I have no ideas on how to implement a XmlSerializer subclass at the moment.

    - .NET service does not stop normally during shutdown Okay, if you're pretty sure that OnStop() normally works well, it must have something to do with the shutdown. Perhaps your service critically depends on other services that have already stopped by the time your OnStop() starts running. Thus gumming up your StopService() method. You'd normally manage that with service dependencies. Wild guess by the way, I'd recommend you add tracing so you really know what is going on.

When I call this method on a file of this size I get the WebException with the message of: "The remote server returned an error: 213 1722_" Well, as you can see the 213 File Status response is fine except that the last '7' in the size is now a '_' .....

I have difficulties connecting to my SQL Server Express edition.

The Server and its SQL Browser are both running and named pipes are enabled,

even if I am not sure why it would return such an error since I only try to connect to my localhost.

My connection string is currently:

Data Source=localhost\SQLEXPRESS;Integrated Security=True;Pooling=False

the initial catalog is not yet set, because I try to use the connection (System.Data.SqlClient.SQLConnection) to create a new database by ddl.

The resulting error is:

provider: Named Pipes-Provider, error: 40

Connection to SQL-Server could not be established

Any suggestion greatly appreciated.
