Game Technologies: DirectX, XNA, XACT, etc. DirectX8 and Vista Compatibility
(split from http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1221168 to make a new question) It is interesting that you say that because I am testing a VB6 app that was working fine on XP and below but now fails on Vista when it tries to create a DirectX8 object, specifically Set oDX = new DirectX8 throws Error 429, ActiveX failed to create component. Running in XP SP2 compatibility mode does not work either. I would be really grateful if anyone has any ideas on this. I also tried running the latest DX9 redistributable because I heard that was providing backward compatibility, but to no avail. Thanks. I am awaiting a reply from the DirectX team - their response time ...Show All

Software Development for Windows Vista Live UDF
Hello There, What is Live UDF Does the optical platform support third party UDF implementations How do we ensure compatibility of Live UDF with OSTA standard Rgds, Ok, let me try to address some of your questions. How do I format as a application Call the command prompt format command. How do I open and close the door Use the IOCTL_STORAGE_EJECT_MEDIA and IOCTL_STORAGE_LOAD_MEDIA. How do I detect media type My answer may not be the best, but I suggest using scsi pass through IOCTL to issue a Get Configuration command to the drive and deduce the current media type from the current profile.

Visual Basic Execute Code on Application Exit
I need to find out how to add a confirmation dialog box if the application is going to exit, ie i call application.exit() or the last form is being closed. I need my app to confirm the exit with the user and also perform some maintenance type tasks before it exists as well. is that all i only have to put that in all 50 forms, well thats a whole lot easier than finding out what line or few lines of code it will take to abort the shutdown in the code i already have. Not too mention your method is too redundant, which beyond making the application larger makes it harder to update the shutdown process for future versions. ...Show All
Game Technologies: DirectX, XNA, XACT, etc. XInput or DirectInput?
I need to interface a Playstation 2 controller through USB adapter with my application. A group of us are recreating Guitar Hero (kinda) as our final project in our Software Engineering course. I would just use the 360 Version of the guitar but it's not yet released. I was wondering whether I should use XInput or DirectInput. I've read that XInput is best for the 360 Controller, but what about a joystick through USB Hmm, I never thought about that. Although that is true, Managed DirectX has been let go though, so I don't know if the current version of the Managed DirectInput reference is going to still work in later versions of .NET. I assume it will, but there's no telling kinda like DirectDraw. Mic ...Show All
Visual Studio Team System Data Generation Plan unable to delete tables with foreign keys
Hi there. I am using the CTP4 of VS for DB professionals and it is awesome.! One question I have is this. I have a database with some 80+ tables. I am only interested in 2 tables. I created a datageneration plan to populate these 2 tables. The IDE picks up all of the correct foreign relationship/constrains and populate the join tables as well. This works great. However, when I run this data generation a second time, I get errors all over. It complaints that it can't delete rows on tables with foreign keys. It seems that it forgets the join relationships that it just populate... I have pull the schema from a production db and created a brand new one on my test server. So initially there is no data on the tables. Is there an option that I ...Show All
