• Game Technologies: DirectX, XNA, XACT, etc. Quadtree project

  I have started a Quadtree project. It can be downloaded at http://www.codeplex.com/quadtreeload I would be interested in comments on the direction I am taking on the Quadtree DrawableGameComponent. I have included a test program called JoshGameXNA. But, open the QuadtreeComponentLib solution and just set JoshGameXNA project as the startup project. Excuse my C#, but I'm new to it. Any construction comments are welcome. It's seems you may have to click on "more releases" to get to the "Special Build 0.1.1" project. Not sure why..... I have now added the ability to put static objects into the quadtree.  The test program adds 1,000 rocks into the quadtree and it renders it all really fast. One issue I need to work ...Show All

• Software Development for Windows Vista Standard User Analyzer causes COM and ActiveX to fail

  We have a legacy application programmed in C++ and MFC that runs on Windows 2000 and XP but has problems with COM and ActiveX when run on VISTA. This app is built with Visual Studio 2003. I remotely debugged this app running on Vista from my development machine and found that the COM and ActiveX problems is the app trying to instantiate the COM components but they return E_ACCESSDENIED. I have checked the following: 1. The COM components on both my development machine (XP) and the test machine (VISTA) have the same ACL’s. 2. The access denied problem occurs if I am logged into the test machine (VISTA) as a local user or an administrator (Admin Approval Mode). 3. I added: HRESULT hr ...Show All

• Software Development for Windows Vista Multiple NTVDM.exe

  I work for a corporation(TimeManagement Corporation) that uses a 16 bit application that runs in the virtual dos machine. Two years ago Microsoft released a security patch(MS04-012) that caused each new 16-bit file to open in it's own ntvdm thus not allowing our 16-bit application to communicate with other files that it calls. We contacted Microsoft about this but it was not taken care of until we posted on a forum. They then released a hotfix(KB841559) to fix this issue. We are now having the same problem with MS Windows Vista and would like to know if we can get a fix for this issue to allow our program to be compatable again.

• Game Technologies: DirectX, XNA, XACT, etc. 3d games 101

  Ok, once one has mastered the art of 2d games, what are the best tutorials out there to jump into the 3d world As said it is probably, or most likely, definately the best to wait for the content pipeline to be fixed. If you cannot wait though you can have a look in example at Kukyona's work, which has created a basic 3D terrain engine. No fancy stuff going on, but it does show what you can do with XNA already. To see his work in action: http://kukyona.blogspot.com/ Another sample is the free floating camera control which can be found on the following site: http://crenna.spaces.live.com/blog/cns!1DB5AC7D2F969F08!182.entry There are more out there, in example see the xbox360homebrew.com tutorials li ...Show All

• Visual Studio Express Editions Starter Kit Amazon-enabled Movie Collection

  I have installed this kit and when I use the search feature to find a movie and try to add it to my collection more often than not I get the message " "There was a problem adding this DVD to the collection. " I can't figure out why it sometimes allows the movie to be added and sometimes not. Any ideas would be appreciated. OK, Figured it out. For anyone else who is having a similar problem, the Actor field is also too small and should be changed to (max) per Lisa's procedure. I figured this out by commenting out the Catch exception and replacing it with Finally which then allowed the program to hang up when it tried to post the Actor value from Amazon to the actor field. thanks again ...Show All

• Visual C# changing label from program.cs

  ok well i have a listener thread in program.cs that listens for messages from my NetworkStream and then needs to acces a label on my Form1 ive tried Client. Form1 test = new Client. Form1 (); test.label1.Text = data; Client being my application name lable1 is probably a label in Form1 class and it cannot be access here because it has by default private modifier. The best way to do it to create a property in Form1 Class like this: public string SetLabelText { get { return this.label1.Text; } set { this.label1.Text = value; } } Put the above code in Form1 class And access it from other class like this: Client. Form1 test = new Client. Form1 (); test. SetLa ...Show All

• SQL Server Restting value in id column

  hi guys i was wondering if anyone could help me, i have a table with a field called id that did have numbers 1,2,3,4,5,6,7,8 and so on! but after some tinkering i have removed a few value and added more so i now have 1, 4,8,19,20 and so on! i was wondering if i can run a query to update those values and return them to 1,2,3,4,5,6,7,8 and so on i know i shouldnt of been messing! but how on earth do you learn without mistakes!!! Cheers Tupps Is this id column an identity If so, you can't really get back the missed values easily. Check out identity_insert in BOL for a way to fill gaps, but generally you should not use identities values if you care about the values. It is just a method to get a unique value, not a sequential ...Show All

• Visual C# Run application from WindowsService

  I have a windows service that needs to start a windows application at a certain time, but when it runs the application, I can't see it, but I can see it in the taskmanager. Any ideas why could be because its running under your account but in a seperate session. You could see what happens if you try to tell it to interact with the desktop (again from the same place you changed the user account to use) however I would advise against this as its bad practice. you should instead create a winform app that sits in the background which does this instead :-) ...Show All

• Visual Studio 2008 (Pre-release) Virtualizing

  I'd like to use the VirtualizedStackPanel to display almost 3000 rows of data. Please see code below. My hope was that since the only controls created were the first few rows that show on the screen the virtualizing panel would return quickly after the 3000 rows were bound to it. In the code below, it does not seem to matter if I set my ListView's VirtualizingStackPanel.IsVirtualizing to True or False, it still takes about 15 seconds to bind the data. This is actually blazing fast compared to WinForms which could never even do this, but I wonder if vitualizing is really working, because it does not seem to be affecting the time it takes to display the control after binding the data. Are my assumptions about the effects of virtualizing i ...Show All

• Visual Studio 2008 (Pre-release) netTcpBinding wsHttpBinding which is better for a LAN environment?.

  Hello, I was programming a WCF service only for clients running inside a LAN, i tried out both the netTcpBinding and wsHttpBinding endpoints. I would like to get experts opinion on which one is better for my case. My clients are standalone applications(windows desktop clients) running in a Windows 2003 LAN environment. Also incase in the future some webclients client wants to talk to our service, can a netTcpBinding expose the wsdl interfaces . I tried the following and got some errors. net.tcp://localhost:8000/Myservice/service1 wsdl. is this possible or,  wsdl can be exposed only for http based bindings .   Thanks,         Hi, ...Show All
