• Game Technologies: DirectX, XNA, XACT, etc. How does Vector3.Transform work?

  I have the following matrix 1 0 0 0 0 -1 0 0 0 0 -1 0 0 1 0 1 and transform a zero vector by that. There is a transformation in the matrix, but I can't figure out how the math is done. Shouldn't this just be a 4x4 matrix multiplied by a 4x1 matrix For the fourth component of the vector, I tried just using 1. But when I multiplied them together by hand, I get a 0 vector. What am I missing Thanks. -Nick So turns out if I change it to public void SetGlobalMatrix(Matrix parent) { Matrix quat = Matrix.CreateFromQuaternion(m_orientation); m_globalTransformation = m_translation * parent; Matrix temp = quat * m_globalTransformation; foreach (Bone bone in m_children) { bone.SetGlobalMatrix(temp); ...Show All

• Visual C# Settings file -v- app.config ?

  This might be a dumb question, but what is the difference between a Settings.settings file and app.config When should I use one over the other The help file tells me how to use each one, but doesn't seem to explain why to use each one in preference to the other. It seems daft to me to store config data in two separate files - more hassles at install time updating multiple files rather than just one. Basically, App.config is an “older” mechanism to define and read simple key/value combinations. MySettings is a newer version of this mechanism which allows you to do the same, but also allows the developer to define and update objects and their properties. Also using a nifty interface, during designtim ...Show All

When DB Pro is released, will it support the Standard Edition as well Thanks - Amos. Yesterday I was at a MS Event and seen this product.  I had my credit card ready and willing to buy it right then and there.  But with it only supporting Ent and Dev version now I am not so sure.     I have 40 production sql servers in house and only a few are Enterprise, rest are all standard.  I would like to suggest that you strongly consider supporting the standard edition of SQl 2005.  IF you cant I think you get ready to explain why, ...Show All
