• Game Technologies: DirectX, XNA, XACT, etc. Shooting

  What code could u use for something to shoot. would this event work: if(GamePad.GetState(PlayerIndex.one).Buttons.A == ButtonState.pressed) shoot = true; if(Shoot = True) { bullet.X = Player.X; bullet.Y = Player.Y; buller.Y += bulletSpeed; shoot = false; } An easier way, that would be much more scalable is to possibly use a list of bullets, that contain bullets that have been fire. Check the input of the player, if the button to shoot is pressed, create a new bullet, and add it to the list of bullets. And every frame, you update all the bullets. struct myBullet { int x, y; int speed; int damage; } List<myBullet> _Bullets; public void CreateBullet() { myBullet bull = new myBullet ...Show All

• SQL Server Address field problem.

  I have a number of text boxes (one on top of the other) to display the addresses in my report. I have Address_name, Address1, Address2, Address_city, Address_State, Address_PostalCode - Each with its own text box except for the city, state, and postal code for which I just combined the fields. However, I have many who do not have any data for Address2 and don't want an empty line in the address. Is there an expression I can use to display the next line or move/shift up the remaining parts of the address Would the iif and isnothing expressions be helpful, and if so, how do I write it correctly I see, thanks for the info. I will try this in about an hour or so, I'll post back and give you an update. Than ...Show All

• Visual C# Help refactoring a method

  I want to get rid of repetative code in the attached method I created (like in my If statements as you can obviously see, most is repeated but just for different product types) but not sure the best way to restrucure it: http: / / www. webfound. net/ forum_ posts/ repetative. txt Hi, I would use the Simple factory design pattern to create instance of Product. And then I will create an interface named IProductLoader (for example). I will create another abstract class named BaseProductLoader that implements IProductLoader and give basic implementation to the Load operation. Then I will add 3 classes that inherit the BaseProductLoader: SampleProductLoader, TrackProductLoader and AlbumProductLoader. I hope this helps ...Show All

• SQL Server SQL Server 2005 Business Intelligence Development Studio Not installed with Reporting Services

  I have SQL 2005 reporting services installed and running, however I do not have the BI dev studio installed and cannot figure out how to get it installed. The report server is operating correctly since I have developed reports on another pc using VS 2005 and uploaded them to the server.
