  Hi All, I'm migrating a perfectly working app from .Net 1.1 to .Net 2.0 b2 and I'm having very hard time to understand why I'm getting the following exception: "An error occurred creating the configuration section handler for ColumnMappings: Could not load type 'SingleTagSectionHandler' from assembly 'System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

• Tommy_ivi Implementing Optimistic Concurrency Control using Datasets

  I have designed a data access layer in which all the updates happen using the data adapter.update(dataset) method. The problem I'm facing is that by default the 'Last In Wins' concurrency is being done. I mean the last update is potentially overwriting all the other updates done. The requirement is to implement an optimistic concurrency approach meaning that if two users A and B have datasets of table X and if User A updates the table X ...Show All

• Gidon J Forcibly unload an interop assembly w/ blocked unmanaged thread?

  I have the situation where I think my 3rd-party unmanaged COM object, which has opened a critical system resource, is blocked on a thread or something. In C#, .NET 2.0, I call FinalReleaseComObject() on my object, which returns 0, and then set the varible to null. I tried forcing a garbage collection and it didn't work (I know, it's bad, but I'm trying everything). Watching it run via depends.exe, I see all my other 3rd-party COM DLLs unload ...Show All

• Bob Walter Timer - in W98 fails, in WinXP OK

  I think, that I found another bug in .NET Framework 1.1. My programs works very well under Windows XP, but under W98 (tested on many computers) fails. After weeks of research I realized that one problems is in the System::Timers::Timer class. I use timer like this: System::Timers::Timer* timer = new System::Timers::Timer(1000); timer->Elapsed += new System::Timers::ElapsedEventHandler( this , CasVyprsel); timer->AutoReset = tr ...Show All

• JimReid MissingSchemaAction.AddWithKey

  This would seem to act differently in VS2005 DataAdapter than it did in VS2003. In 2003 constraints would only be added if all primary keys were in the select statement that included joins. i.e. Select * From table1 inner join table2 on table1.id = table2.id would generate a constraint, however the next statement would not generate any constraint i.e. Select table1.* From table1 inner join table2 on table1.id = table2.id both id c ...Show All

• CBDenver Deserializing off a network stream blocks indefinately even when data present

  I seem to have kind of a strange problem here. I'm implementing an RTI where we use xml messages to pass back and forth between the RTI and the Federates. I'm using something similar to the following code: C# Code: XmlSerializer serializer = new XmlSerializer( typeof (RtiMsg), RtiMsg.RtiTypes); RtiMsg msg = new RtiMsg(); msg = (RtiMsg)serializer.Deserialize(netstream); When it gets to the Deserialize(stream), it just blocks forev ...Show All

• L1Alpha01 Why are mapped (network) drives unidentifiable in Windows Service applications?

  It is noticed that mapped drives (Network drives) can not be identified in Windows Service applications, but are identifiable in common Windows applications.

• srowan SqlHelper Obsolete?

  Hi I'm a newbie here so sorry if I've posted to the wrong group, I'm also a newbie to Application Blocks and have just downloaded them (at least the Enterprise Libraru June2005 which is supposed to contain all the MAB's). Anyhow, it appears that SqlHelper is not in the Enterprise Library. There is something called SqlCommandWrapper which appears to do the same thing plus much more. So, my question is : Is SqlHelper obsolete or is it a j ...Show All
