• Game Technologies: DirectX, XNA, XACT, etc. C++ or C# ??

  I've been programming professionally for 8 years - all web and business programming in ASP, ASP.NET, and Java. I have a very solid knowledge of OO application development but I'm simply not challenged. The apps are all the same - build database, put front end on database to present data, allow data to be edited/updated, allow data to be deleted. Wash-rinse-repeat. I've been a gamer since I was 8 and I still play games like mad (own a PSP, DS, Xbox, and XBox360). It seems to be the only thing that has really stuck with me (I know, pathetic for a 36 year old! ) and I feel like I need to modify my skillset and break into game programming. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Terrain Rendering

  I have a quick question... What are some of the best/simplest ways to render large terrains for games such as a MMO or a FPS like Far Cry I have skimmed over some LOD stuff using quadtrees and this seems to be ok but I was thinking of using an LOD technique that changes with distance from camera. I am not sure what this is called. But i was wondering if this would be a good way to go about it. Thanks in advance. Sorry to hijack a bit here. But I have heard abou streadmin/paging before, but it is hard to find any info on it. Info like, how big should the terrain parts be, and how do you load the other terrain In an other thread with low ...Show All

• Smart Device Development Visual Studio 2005-Connecting Windows CE.NET Device

  Hi Guys I am trying to install a Visual Basic 2005 application on a windows CE.NET device. I cannot see a CE.NET device in the list so I tried selecting Windows CE 5.0. It gave me a message cannot create a file as the file name already exists. Is there any option to connect to a Windows CE.NET device Any inputs will be highly appreciated. CE 4.x (AKA CE.Net) is not supported by VS 2005. NETCF V2 SP1 currently in beta would add CE 4.2 runtime support.

• .NET Development .NET Framework 2.0 dependencies

  When I install .NET Framework 2.0 on Win2000 SP1 machine, a popup dialog appears saying that it require MS Installer 3.0.  When I install MS Installer 3.0 on that machine, it then require Win2000 SP3 which is big group of components. I am surprised when I try to deploy my .NET 2.0 application to customer's Win2000 or lower computer, there are big group of prerequisites needed.  Honestly, I am not dare to do Win2000 SP3 upgrade to customers' computers. Any suggestion I don't think we can draw any conclusions about what the shipping Framework 2.0's final requirements will be.  It is possible that the curren ...Show All

• .NET Development Is this a bug in IPAddress?

  I have recently run across something that appears to be a bug in the IPAddress class.  I am including a source example below.  In short, the IPAddress class will return a byte array using the GetAddressBytes() method, however, that byte array can not be used in the constructor of another IPAddress object.  It looks like IPAddress requires the byte array used in a constructor to be 16 bytes, but the one returned by the GetAddressBytes() method is only 4 bytes. In addition, another minor bug is that when the class throws an ArgumentException, the Message property is set to the parameter name, and the Parameter property is s ...Show All

  I created a Package in the Import\Export Wizard, requested it be Saved on the server, and ran the package. But I can’t find any trace of the Package under SQL Server Management Studio. Where has it gone TIA, Barkingdog P.S. I remember the “old” days of sql 2000 where packages were proudly displayed, prominently, under the ”Data Transformation Services” option folder.
