  Hello, I'm making some changes to an old application - I can run the app no problem on one machine, but on the one I'd really like to use I receive the following error: run-time Error -2147467259(80004005) Invalid Authorization Specification.

What happens if a object is too big, and is inside 2 or more octree leafs Should the object be divided in 2 If not wouldn't the object be drawn twice Or this should never happen If the object will get divided the recursive function should exit and stop dividing Thank you Depends on what algorithm you are using and what you want to do with it.

• .NET Development Visual Studio .NET project templates for creating Windows Communication Foundation (Indigo) applications

  I am getting started with using WFC services and wanted to know what project template I should use   Are there any project templates available   Thanks Ralaph Ralph, we have a few templates available for WCF projects in our add-on pack for Visual Studio. You can download the version that goes along with the Janurary WinFX CTP here [1]. You don't actually need a WCF-specific template to get started, however. If I'm writing a web-hosted service, I usually start with a library project, and just add a .svc file to the solution. If I'm writing a self-hosted service, I'll start with a console p ...Show All

• SQL Server ODBC & Multi-threading

  I'm working on a C# (2005) app that requires shooting a large number of queries via Odbc, wait until the last one is done and then compute an overall result. Since the queries are not interdependent, I would like to get them to run concurrently on multiple threads. I did manage to get several queries run on different threads but the response time for the same query varies dramatically when another query is running concurently (even on a different ODBC connection). All is as if something was queing those queries regardless of the threads and/or the connection objects being used. Basically when I run a very simple query q1 (thread 1 c ...Show All
