• Visual Studio 2008 (Pre-release) DLINQ Nice to have: Returning a unique record

  While reading the DLinq Technical Overview document and playing around with Linq I noticed the First method on a Table<T> object, but no 'Unique' method. While the 'First' method returns the first object from your query, I'd like DLinq to have a 'Unique' method that also returns a single object, but also gives a compile time error if the given conditions do not specify an unique record. This way the compiler checks the correctness of the c ...Show All

• Visual Studio Team System comparing old and new values in __success macro

  Hi there, How do I express the condition that a parameter passed by reference remains unchanged after the function returns something like this __success(__oldvalue(parameter) == __newvalue(parameter)) But I do not want to make the parameter a constant reference because I want to change it when the function fails.  And I want to express the property that the function suceeds if the parameter remains unchanged. ...Show All

• SQL Server Fuzzy Lookup problems.

  Fuzzy lookup seems to be causing some problems to me. It seems to work at times and doesn't at other times.

Now I'm currently getting the following error: [Fuzzy Lookup [248]] Error: An OLE DB error has occurred. Error code: 0x80004005 ...Show All

• Software Development for Windows Vista How does it compare to the ISV's like K2 & Captaris Teamplate??

  This weekend I'm planning to take a dive into WWF, very excited about the potential of this new platform. One of the first things I want to find out is how WWF compares to other workflow solutions. I've worked with both K2.net and Captaris Teamplate, from which I definitely prefer the first one. Of course the integration in MS products will be far better, but how does it perform, how do the BAM tools compare, does it bring easier user managemen ...Show All
