• Visual C# Analog Clock algorithm?

  Hello, I have a lot of source code for how to create an anlog clock but i cant understand the algorithm, esp use of 'sin' and 'cos', so please any one can help me with a tutorial for the understanding of the algorithm, Thanks and regards I'll take this chanllenge... All these kind of algorithms draw lines from a point (center of your clock) with different length/width/color (hour arm, minute arm, second arm), towards different angle (different time). Assume your clock center is at (x,y), the length of the arm is r, and the angle is a, then you need to calculate a second point (x1, y1) so you can draw a line between (x,y) and (x1, y1) to paint a clock arm. If you have difficulties with 'sin' and 'cos', you can just use ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Heightmap Terrain Component

  I thought the whole component concept was pretty cool. So I threw together a quick heightmap terrain component. http://i9.photobucket.com/albums/a59/craigory666/heightMapTerrain.jpg http://i9.photobucket.com/albums/a59/craigory666/heightMapTerrain2.jpg http://i9.photobucket.com/albums/a59/craigory666/heightmapprop.jpg It should work with square .raw files, and for the effectPath I'm just using the default texture shader found in the help file. The view and projection matrices of the terrain are exposed, so you should be able to hook up whatever camera you have going and just update the terrains view, and projection matrices during your games update. using System; using System.Collections.Generic; using System.IO; using Microsoft.Xna.Fr ...Show All

• SQL Server I made a mistake about service name and the transmission queue got filled of them

  I want to use SSB as a mean to thread multiple SP invocation of the same procedure. When I launched the initator processes it created in the transmission queue error messages saying for each of them that it is an invalid target service name. The view (sys.transmission_queue) records them in this way in the status column: "The target service name could not be found. Ensure that the service name is specified correctly and/or the routing information has been supplied." Services and queues and activation procedure are all defined into the same database. I drop services and queues, and i tried to create a service with the initial wrong name. Nothing happened. Thanks vour your help Thanks, I tried to ...Show All

• Visual C++ How to develop a wizard with Visual C++ 2005 ?

  Hi, where can I find a tutorial on how to write a wizard I have browsed the web and newsgroups for more than a day, and I can't find a simple howto. I am quite new to MFC and Win32 APIs. I believe than a wizard is a property sheet with property pages, and the PSH_WIZARD97 flag. I have found the CPropertySheet class, which define the AddPage method to add property pages (through the CPropertyPage class). I have written a CMyPropertySheet class inheriting from CPropertySheet, and calling AddPage on CPropertyPage instance that I have to define. I saw a code somewhere for implementing CPropertySheet by doing something like this : class CMyPropertySheet : public CPropertySheet { DECLARE_DYNAMIC(CMyPropertySheet ) public: CMyPropertySheet (UI ...Show All

• SQL Server Create a calculated member on one measure.

  I have a Version dimension which is used to break out the Net measure by 'Actual' or 'Budget'. Net is the only measure I'm using. By not using the Version dimsion. The net is incorrectly totaled by both values. Both are not used together. 'Actual' and 'Budget' are the only two members of the Version dimension. I want to add a third member which subtracts 'Budget' Net measure from the 'Actual' Net measure and call it variance. A caculated measure isn't working for me because obviously subtracting Actual - Budget doesn't work so well. Can anyone help me with that You add this statement to the MDX Script of the cube.
