  When will a new MSF (MS Solution Framework) be released detailing the SDLC using workflows can we see some examples / doco of WF leveraging LINQ I've read somewhere that Don Box says that "objects are done". how does WF change OOD How does WF slot into the Software Factories concept Will the final release of WF be extensible in the sense that it is able to utilize the Rete MS Business Rules Engine or some kind of backward-chaining inference engine These are interesting questions.  I would be interested in seeing someone demonstrate a WF application that used LINQ and how these two technologies wo ...Show All

• Windows Forms Custom displaymember and valuemember in a bound Combobox?

  I have created a form with a combobox that is bound to the database table field "State". The State field use numeric values 0,1,2,3,4 according to the state. The problem is that i don't want to show the exact same values it retrieves from DB, i rather want to display a list of possible "States", with custom text corresponding to the value. Example: The value 0 actually means "Stopped". So i want it to add the option "Stopped" (displaymember) in the list, with value 0. Whenever i select "Stopped" in the list and save the form, i want the value "0" to be saved in the database. How do i do this I k ...Show All

  just a question.... my web project is using SQL Express2005 and ASP.NET and C#. my web hosting company only have MSsql2000. would there be any conflict with regards to my database im sorry if i sound dumb. im a newbie to this. thanks a lot! There will not be a conflict but you may have to make code changes, there are a fair number of features in SQL Express that will not work with SQL 2000. I suggest downloading a copy of MSDE for yourself(which is free) so you can test before going live with the hoster. ...Show All

• .NET Development Convert Untyped Dataset to Typed Dataset

  I am using the Enterprise Library which returns untyped dataset. I have a typed dataset that was generated from the same stored procedure that the enterprise library calls. I need to convert the untyped dataset that I am getting into a typed dataset that will be utilized by the presentation layer. I tried using DataSet.Merge but it just adds the untyped table into the typed dataset as a second table. How can I make this work Thanks, Steve Hi! You need to cast it to the typed dataset like as follow: TypedDataSet myTypedDataSet = (TypedDataSet)GetUntypedDataSet(); Where myTypedDataSet is variable of TypedDataSet and GetUntype ...Show All

• Visual Studio 2008 (Pre-release) Lambdas in Custom Attributes

  I want to pursue the concept of embedding lamdbas in custom attributes. It is not supported today to my knowledge but I believe could be very valuable for DLINQ and more.  public class Customer {   [Association((c, o) => c.CustomerID == o.CustomerID && o.Status == OrderStatus.Incomplete)]   public Order[] IncompleteOrders; } I believe that a syntax such as this would generalize the join conditions that are supported by AssociationAttribute and allow for additional conditions. In that way, queries need not repeat those conditions.  Note that regardless of whether DLINQ adopts this, there is a deeper is ...Show All
