• Game Technologies: DirectX, XNA, XACT, etc. Checking for capabilities

  I have a simply game where I'm drawing a flat terrain made up of tiles, each tile being made up of two triangles, and I'm using index + vertex buffers. On my computer (Geforce 6600GT, AMD Barthon 2600+) everything works fine. On my laptop (Centrino 1.7, Intel on-board graphics) nothing shows, so I guess the vertices aren't being drawn. I'm assuming this is because the on-board card does not support some feature that the 6600GT supports. I checked the GraphicDevice.SoftwareVertexProcessing property, and on my computer it is false, while on the laptop it is true, so I'm assuming that's set right, since most on-board cards don't support much hardware stuff. I'm also using a BasicEffect so that might be it.. I guess I have to check some ...Show All

• SQL Server OLE DB Source to Flat File Destintation using Fixed Width Columns - determining source column width

  Hi, I am trying to create a program that transfers tables to flat files. At this point in time, I have suceeded in created one that creates delimited files. However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically. Is there a way to programatically determine the width of a column from the source table I can not seem to find any kind of function or member that stores this information or allows me to retrieve it. I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one. I've continued my research in trying to figure out a way, but I can't seem to find anythin ...Show All

• Visual Studio 2008 (Pre-release) HOW TO get list of ClientChannel(s) when InstanceContextMode = Single

  I have a service that is a multi-threaded singleton: [ ServiceBehavior (ConcurrencyMode = ConcurrencyMode .Multiple, InstanceContextMode = InstanceContextMode .Single)] I also want to implement a duplex contract on this service so that the service can notify any clients of service-specific state changes. How do I [from within the service instance logic] dynamically get the currently connected client channels' callback interfaces - so that I can run down through them calling the state-changed handler operation Or, is there an event that I can hook into in my service that would notify me when a client connects/disconnects This would allow me to maintain the collection of callback interfaces - if the core WCF implementation does ...Show All

• .NET Development Webservice consumes all the available bandwidth.

                   We are on the test phase of a windows-webservice-Oracle application.Clients would connect the webservice through VPN or VSAT. VPN users would directly connect with the webserver,where VSAT user will connect with the VSAT server which will be routed to the webserver. Now the VPN users have an average bandwidth of 512 kbps and VSAT users have an average of bandwidth 360 kbps.There would be an average of 30 users at a time whom would connect either through VSAT or VPN. Now,if we connect through VSAT environment it runs out of bandwidth.The transacted data may reach upto 1 MB for each user. The web server memory is 2GB.We haven't implemented cl ...Show All

• .NET Development How come Console.WriteLine() does not work any more

  Hi all, I have a C# winform application. If users run it from the command lines and pass a /Help or / to it, it does not invoke the winform, but instead uses the Console.WriteLine to display the help and then exit. I know for sure this works before, at least prior to my upgrading the VS2005 with SP1. Now suddenly, the WriteLine() does not work any more. If I enter /Help or / , the WriteLine() basically executed but does not write any thing on the console. And then the program exits ...peacefully. Note that I debug the code and indeed the WriteLine()s are executed. Within the VS IDE, it does write the messages to the output panel. But from the DOS command, nothing is displayed. Here is the code: static int Main( string ...Show All

• SQL Server Suggestions for SQL 2005 Setup

  OK we currently have a single SQL 2000 Server for our DW with a DR SQL 2000 Server. We are wanting to create a setup where we have a Failover Cluster of SQL 2005 here at the main office with a DR SQL 2005 system at our DR site. My question is... How would you all do the failover and stuff How many servers would I need and what would be the job/role for each server. Some things to take note we are implimenting a SAN in our network and we are also implimenting a Virtual Server system on our network. To my understanding you do not really wish to run SQL Servers on a Virtual machine if possible. So I am already planning on making the SQL Servers Physical systems. We are also planning on putting the DB's on the SAN and have the SAN replicate a ...Show All

• Visual Studio Express Editions How to use sendinput()?

  I have been looking into simulating mouse movements and clicks for a while and sendinput seems to be the best choice. I can't find any examples of it working and I'm not experienced enough to work it out without any help so I was wondering if you guys could give me a hand. Could you just give me an example of a program moving and clicking the mouse Also, would this work outside the application Thanks in advance Matt. well im no good at this either but it seems to me as though using ur code, the mouse could keep moving "a" and the speed; change the sleep number. ...Show All

• Internet Explorer Development Still no solution?

  Having an intermittent problem printing To: From: CC: Subject: Attachments: headers on emails. Usually happens with larger emails or emails with large attachments or emails that have been replied to or forwarded from other people. Have installed Generic/text printer and sent the email to this printer but sometimes the headers are still missing even printing this way. I have if I open the offending email and highlight just one or two words in the text of the email eg Dear John and then print the email using my HP printer (not as text on Generic printer) - the headers then print and so does the selected words. Don't suggest using Outlook as often we only print the first page of emails as we already have the rest of the email on file especial ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Ray intersection with an octtree scene manager?

  I'm developing an Octtree Scene Manager for XNA Game Studio Express, which is almost ready to release once I have a codeplex project for it. I have a question for the people on this forum about a feature. Should I add Ray or LineSegment intersection testing (which I think would be must faster than some other methods) or should that be left to some other collision testing components An octree (in this case a "loose" octree) is very fast at finding ray intersections with areas (cube), but I'm trying to decide if it is the responsiblity of an octree to do this or should it just worry about display issues. What do you think For a spatial subdivision structure to be useful, then the users of that structure need t ...Show All

• SQL Server Diagram to Image

• Community Chat Creating A new OS

  Hello, I just wanted to make a question What knowledge would it take to make A operating system if you could tell me Cause I am starting to get into building program it may take A long time but dont worry one day your data will be safer then ever I am hoping to do a couple of things in here against bug/virus Encryption and hard ways to get past stuff... If someone would be willing to help me out... Danka sir! I don't think I'm oversimplifying the problem any when I say that you'll need to know just about everything. I'd suggest you start by reading as much as you can on topics like x86 assembly language and PC architecture. Keep in mind that any resources you find specifically related to designing/writing operating systems ...Show All
